Enhancing Control of Highly Pathogenic Avian Influenza in Developing Countries through Compensation: Issues and Good Practice

12.12.2006 957 views
Executive Summary

Highly pathogenic avian influenza (HPAI) under current conditions poses a major risk to human and animal health. Efforts to contain the disease are therefore in national and global interest. As the most widely practiced control methods for poultry involve culling birds that are infected or in regions immediately around infected animals, the most common practice to ensure the cooperation of owners of birds is to compensate them for the culling of their animals to achieve this public goal. Early identification of HPAI and the imme­diate culling of diseased or suspected animals are critical elements of reducing the risk of the disease spreading. The international com­munity and national governments have responded to this challenge by establishing funding mechanisms to enable compensation to as­sist in this strategy.

Payment of compensation to farmers whose animals are being culled enhances producer cooperation through better motivation to comply with the disease reporting and culling requirements of dis­ease control packages. It reduces the time lag between an outbreak and containment actions, and hence diminishes the overall cost of control. To the extent that it reduces the virus load, it also reduces the risk of the virus mutating to becoming transmissible from hu­man to human. Enhancing early reporting and complete culling of diseased or suspected birds is thus the first objective of compensa­tion schemes. A second objective can be to reimburse losses of pri­vate citizens who have complied with a disease control process for the public good. This is compatible with the first objective.

While the imperative of disease containment drives compensa­tion schemes, the reality of the severe impact of culling on very poor people cannot be ignored. However, a compensation scheme cannot cover all livelihoods losses caused by livestock disease control and it cannot replace social safety nets. This requires other measures, out­side the scope of this paper.

The report seeks to provide guidelines on good practice for payment of compensation as part of HPAI stamping-out strate­gies. It is meant for national and international managers and proj­ect staff involved in containing HPAI. It responds to a request of the Senior Officials Meeting on Avian and Human Influenza held in Vienna, June 6–7, 2006, and the result of the work of a multidisciplinary team from the World Bank, FAO, and IFPRI. The report is based on review of the well-established literature of compen­sation practices in the developed world, staff interviews, experi­ence, and newly emerging gray literature (project documents, mission reports, and so forth) on compensation in the developing world, and specific field visits to Egypt, Indonesia, and Vietnam.

Preparedness Is Key

An effective and efficient compensation scheme will compensate the appropriate beneficiaries for the ap­propriate losses and at an appropriate level, with only a short interval between culling and payment of the compensation. This will only be possible if a number of elements are already in place before an outbreak. There needs to be appropriate legislation for the control of animal disease in force that spells out clearly the rights and responsibilities of govern­ment, livestock sector and marketing personnel, and farmers in animal disease control. There needs to be widespread awareness of the dangers of the disease and how to mitigate them. Funds have to be readily available and the procedures and sequenc­ing of actions to be followed for compensation need to be agreed in advance. Preparations for the imple­mentation of expedient and transparent payment schemes need to be in place.

Procedures and sequencing of compensation require knowing who to compensate, when, how much, and how, and all the stakeholders have to be aware of and have faith in the system. Widespread knowledge in advance of what the stakes are (in­cluding poultry holdings) and identification of the stakeholders are key elements in improving the gov­ernance of the use of compensation resources, which is especially difficult in emergency situations.

Because preparedness is essential to using cull­ing and compensation effectively and efficiently for disease control, countries need to make a host of arrangements without necessarily having national precedents to guide the way. The present document tries to illustrate key lessons from countries such as Thailand and Vietnam (and others) that have learned by doing and incorporated many of the les­sons in revised strategies. Even with guidelines from elsewhere, national avian influenza committees will still need to negotiate specific arrangements with national stakeholders in a way that fits local condi­tions, and this takes time and effort.

Countries faced with outbreaks before they have their contingency plans in place will need to adopt the most basic measures. Even so, the same issues of who to compensate, when, for what, how, and how much still apply. However, the need to move quick­ly for disease control will force many of the normal oversight tasks to a later date and is likely to make governance issues even more difficult.

Finally, it will be difficult to de-link compensation practices from both changing needs for effective dis­ease control and the issue of equitable production systems change as the disease becomes endemic. This aspect is also introduced briefly in the conclud­ing chapter.

Identification of Beneficiaries

As a general rule, the beneficiaries of compensa­tion are the owners of the animals. Other supply chain participants, such as feed suppliers and mar­ket operators, may also incur losses when livestock production and sales are disrupted by disease, but they have not normally benefited from compensa­tion schemes. The type of production system significantly shapes feasible identification procedures. Large, highly biosecure poultry farms (the so-called sector 1 and 2 under FAO/OIE nomenclature) have generally good inventory records and culling is well controlled. Farmer documents are then a basis for compensation.

Under conditions of contract farming in these systems, ownership of the birds decides the beneficiary. If the contractor is the owner, he/she would be compensated, and takes the responsibility for re­imbursing the integrator. If the integrator owns the bird, he/she will receive the compensation. In a few cases, arrangements have been made to pay the con­tractor for lost income on a wage per day basis, with funds subtracted from the integrator share before payment. The issue of how to incorporate contract growers into compensation process remains a prob­lem that many countries are only now beginning to look into. More attention needs to be addressed to this issue lest it becomes a loophole limiting effec­tive control of the disease.

Identification of the beneficiaries for small en­terprises and back yard systems (the FAO/OIE de­nominated sectors 3 and 4) is more complex, as re­cords are normally not available, and factors such as differential ownership by gender come into play. Sur­veys as part of the preparedness planning (not after the disease emerges), including the identification of ownership patterns, broad awareness of the existence of compensation and payment as an integral part of the stamping-out process, are then key factors to en­sure a broad participation of the sectors 3 and 4.

Type of Losses to Be Compensated

Normally, compensation covers only the so-called direct losses, which include the value of the animals, and sometimes also (in richer countries) the costs re­lated to the disposal of dead animals and cleaning and disinfection. So-called farm-level consequen­tial losses, due to business interruption, movement control, and price effects are not compensated, al­though in many developed countries private insur­ance schemes exist for such losses. Dead animals before culling are often not compensated, however there may be a rationale to do so at least partially where either dead animals have market value (and thus there is the danger they will be sold) or disease control teams cannot respond within 72 hours of dis­ease reporting by the farm in question. In all cases the accurate computation of losses is greatly aided by having adequate farm-level records of poultry holdings, and it will be important to promote such a database prior to disease outbreak. Finally, the lion’s share of actual economic losses to the countries in question may be indirect: lost feed sales, diminished tourism, absenteeism at work, and so forth. These losses are never covered by public compensation schemes. In principle, they could be insurable under private sector contracts outside the livestock sector if risks are well known, but they rarely are.

Setting Compensation Rates

Compensation rates are variously set on the basis of (a) market value; (b) budget availability; and (c) production costs. Setting the cost on the basis of market value, wherever possible, is the preferred policy, as basing the cost on budget availability of­ten leads to underpayment, and hence poor compli­ance with the culling operation, and production cost would favor inefficiencies, and is more complex to establish. Experience that emerges from the review in establishing compensation rates based on market values shows:

•  Compensation rates as a percentage of a refer­ence market price should be set before the dis­ease emerges, as part of an overall preparedness plan, using average pre-outbreak market prices at the farm gate, computed with due regard for seasonality and the transport costs from the local community relative to the reference market. For special category birds (rare breeds, indigenous poultry, fighting cocks, grandparent stock, other bird types), where market prices are not readily available, consultation with the stakeholders is required to set realistic levels.

•  Uniformity of rates across the country and for different classes of birds improves the implemen­tation efficiency of the program, and should be pursued in situations with good control. How­ever, in situations of poor movement control, differentiation by type of bird (layer, broiler) and age/weight of the group might be needed to ft compensation as close as possible with prevailing market prices. An interesting intermediate solu­tion might be to pay not on the basis of numbers but on the basis of the total weight of the flock.

•  Compensation rates should be no less than 50 percent of the reference market value of suspect­ed birds at the farm gate, and no more than 100 percent. The rationale for the preferred range of 75–90 percent of the reference price and multiple considerations for being closer to one or the other limit are discussed in the report. Rates should be considerably lower for diseased birds and even less, but positive, for dead birds, to provide posi­tive incentives for early and complete reporting. Careful attention needs to be paid to bird move­ments during compensation to ensure that an incentive is not being created for the influx of healthy birds to disease zones or diseased birds to disease-free zones.

•  In dealing with small farmers in developing countries, compensation should be paid within 24 hours of culling by cash (or possibly voucher where handling cash presents a security threat and credible local formal financial institutions such as rural post offices are available); any delay is likely to have a significant effect on reporting.

Establishing Awareness

Experience from on-going campaigns highlights the absolute necessity of communication on dis­ease control and compensation, which when done properly may run from 10 percent to 20 percent of the total package cost. The package should contain components of consultation with the beneficiaries, advocacy, and information, using multiple media and channels. The specific messages on compen­sation should explain to affected farmers the need for mandatory culling in cases of suspicion of avi­an influenza as a necessary measure to protect the health of the entire human population. They should contain the principles, procedures and grid of com­pensation levels, precise information on the exact amounts, and payment procedures. Messages and media should be prepared ahead of time with inputs from both technicians and communication special­ists. They should also be consistent over time, since frequent policy and message changes undermine the credibility of the campaign. Private sector opera­tors, such as para-veterinarians, can play a critical role in awareness raising and overall support to the campaign, and their input on retainer fees should be more encouraged than is currently the case.

Payment Systems

To promote early notification of suspected out­breaks, compensation for culled birds must be paid promptly following the birds’ destruction. Critical el­ements from an appropriate payment system follow:

•  Rapid access to adequate funding for immediate deployment as needs arise is essential. Sources typically are government’s own funds from the National Treasury, farmer’s contributions, and those of donor partners. National budgets need contingency funds of at least 3–5 percent of total budget to facilitate a rapid central contribution in the event of an outbreak; alternative contingen­cy planning will be necessary where this is not available.

•  The share of compensation payments in total animal disease control expenditures under out­breaks ranged from 0–45 percent in the cases studied, with a central tendency of about 35 per­cent. Holding large sums as contingency reserves to allow a rapid response engenders a consider­able cost. For compensation planning purposes, the upper range of foreseen culling during a se­vere outbreak should be capped at 10 percent of the national flock. Many outbreaks are controlled with culling of less than 1 percent of the national flock. Once the share of infected and closely asso­ciated birds exceeds 5 percent of the total nation­al flock, vaccination typically starts substituting for culling and compensation. These percent­ages, multiplied by the size of the national flock and again by 75 percent of the average farm-gate poultry price, provides a rough estimate of the range of funds that need to be accessible for compensation payments per se on short notice. Countries that are important poultry exporters and wish to avoid vaccination (such as Thailand under its 2004 outbreak) should plan at the 10 percent (high) limit, countries with little in the way of poultry exports and a large percentage of smallholder poultry producers at 5 percent, and countries with little trade concern, a high degree of biosecurity, and a creditworthy public finance system at 1 percent.

•  The system should be simple enough to be used in difficult field situations and should make use of existing institutions (for example, line minis­tries, veterinary services, financial institutions). It is important to clarify responsibilities in advance, make provincial cross-agency coordination ar­rangements, and establish local contingency funding. If no system is in place when the disease emerges, the focus will need to shift to a greater reliance on ex post independent scrutiny to avoid inordinate delays in paying compensation.

•  Eligibility databases and emergency payment (see above) procedures should be prepared as

part of the emergency part preparedness plans; where lacking, they will both need to be set up when the disease emerges, posing considerable difficulties.

•  The veterinary services (assessing the need and reliability of the culling), the Ministry of Finance (payment), civil authorities (security), and com­munity leadership (transparency) should all be directly involved in the payment process.

•  For sectors 1 and 2, bank transfers are the most adequate instrument; cash payments are the pre­ferred method for those farms of sectors 3 and 4 without banking access. Vouchers are often less credible for immediate motivation of rural house­holds, but may work where they can be integrat­ed with a dense local network of trusted financial institutions, such as rural post offices.

•  To the extent possible, maximum use should be made of local banking entities, producer’s orga­nizations, veterinary services, and nongovern­mental organizations (NGOs). Their fiduciary assessment should be part of the preparedness planning.

The Way Forward

While over time the international public good ar­gument regarding the risk of human-to-human transmission of HPAI might diminish, transmis­sion between animal populations of different countries will continue to be a main reason for in­ternational funding of disease control in develop­ing countries. Moreover, in the likely event of the disease becoming endemic within certain coun­tries, this will have major effect on the poor, and interventions under those conditions therefore deserve international support from an equity per­spective. Stricter disease control requirements will have a major effect on the structure of the industry, with implications still to be clearly identified for the future viability of the sectors 3 and 4. None­theless, compensation is likely to remain neces­sary for many years to come to promote the early eradication of outbreaks and to avoid the spread of transmissible animal diseases.

Under such conditions, compensation will:

•  Become part of modified stamping-out strategies, with probably a lower priority to culling. Clear principles of how stamping-out strategies should evolve, and how compensation fits into such evolving strategies are needed.

•  Have to become more dependent on the coun­tries proven political will to improve the key institutions for animal health, in particular for early alerts and independent disease reporting. The OIE tool for Performance, vision and Strategy (PvS) is a useful instrument to assess govern­ment capabilities. • Be restricted to sectors 3 and 4, and be funded from a mixture of national and international pub­lic funds, the latter in particular for the poorer countries.

• Be funded for the large commercial sectors through private initiatives, probably as a mix between mandatory levies and voluntary insur­ance; in many cases the public sector needs to work with the private sector to find equitable ways to develop these systems.

A sustainable approach to integrated pest management

There is more scrutiny today than ever before regarding conventional herbicides, fungicides and insecticides, and regulations are tightening. “Complete replacement of synthetic chemistries is impractical,” said Nicholas Body, Alltech Crop Science (ACS) European technical manager. “The future of integrated pest management (IPM) programmes will include the best tactics from a variety of approaches, including nutritional and natural technologies, allowing the producers to reduce inputs while maintaining crop quality and improving sustainability measures.“ With today’s global trend among retailers to be very strict on chemical residues, building the best programme, including all type of technologies, is mandatory. “The use of predictive tools, such as disease models, and preventative, such as elicitors of natural defences, allows us to increase the quality of harvest with only a minimal use of conventional pesticides,” said Body. A balanced nutritional programme is a vital component of an effective IPM programme. “An unhealthy plant, from a nutritional standpoint, is not able to defend itself against a potential pathogen attack,” said Body. Healthy plants have a better chance of resisting disease pressures, and bioavailable micronutrients can support plants’ inherent defences. “If you trick a plant into thinking it’s going to be attacked, then the plant can develop its own metabolic pathways to fight the disease,” Body explained. However, plants are not naturally proactive. “They are reactive organisms,” continued Nicolas Body. “Something must trigger a reaction in a plant to be defensive, unlike an immune system that can react on its own. By using biologicals, such as nutritionals and activators, we can elicit a response in the plant.” Efficient crop management is moving towards a more proactive management of inputs. “We’ve been taught to scout fields, find what’s wrong and then fix it,” said Nicolas Body. “We’re moving to a new perspective where we can act on plant and soil health instead of acting on disease.” Better nutrient management, especially nitrogen, is a key component of this movement and is crucial to sustainability. The focus is to reduce the amount of fertiliser applied to fields and hopefully improve the environment by minimising the application of excess nitrogen. Many European farmers are faced with soils that have been depleted after many years in production. These cannot always provide a perfect balance between exported nutrients and the input fertilisation. With a loss in organic matter and beneficial microbes, the soil is also losing its capacity to act as a buffer. Fortunately, conservative and regenerative approaches to soil management are on the rise, and most farmers are implementing these techniques. Body agrees that a total-system approach will serve crop farmers best in the future. “We continue to research how and when to use biologicals — whether it’s natural activators, foliar micronutrients, natural inoculants or biofungicides — with conventional methods in cropping systems to help producers with environmental stewardship,” he explained. “As any market progresses, we see increasing management of smaller and smaller pieces of the total system.” Source - https://www.freshplaza.com

Kenya - Insurtech startup raises $6M Series A to derisk smallholder farmers

Pula, a Kenyan insurtech startup that specialises in digital and agricultural insurance to derisk millions of smallholder farmers across Africa, has closed a Series A investment of $6 million. The round was led by Pan-African early-stage venture capital firm,  TLcom Capital, with participation from nonprofit Women’s World Banking. The raise comes after Pula closed $1 million in seed investment from Rocher Participations with support from Accion Venture Lab, Omidyar Network and several angel investors in 2018. Founded by Rose Goslinga and Thomas Njeru in 2015, Pula delivers agricultural insurance and digital products to help smallholder farmers navigate climate risks, improve their farming practices and bolster their incomes over time. Agriculture insurance has traditionally relied on farm business. In the U.S. or Europe with typically large farms, an average insurance premium is $1,000. But in Africa, where smallholding or small-scale farms are the norms, the number stands at an average of $4. It is particularly telling that the value of agricultural insurance premiums in Africa represents less than 1 percent of the world’s total when the continent has 17 percent of the world’s arable land. This disparity stems from the fact that the traditional method of calculating insurance through farm visits is often unaffordable for these smallholder farmers. Thus, they are often neglected from financial protection against climate risks like flood, drought, pestilence and hail. Pula is solving this problem by using technology and data. Through its Area Yield Index Insurance product, the insurtech startup leverages machine learning, crop cuts experiments and data points relating to weather patterns and farmer losses, to build products that cater to various risks. But getting farmers on board has never been easy, Goslinga told TechCrunch. According to her, Pula has understood not to sell insurance directly to small-scale farmers, because they can suffer from optimism bias. “Some think a climate disaster wouldn’t hit their farms for a particular season; hence, they don’t ask for insurance initially. But if they witness any of these climate risks during the season, they would want to get insurance, which is counterproductive to Pula,” said the founder in a phone call. So the startup instead partners with banks. Banks provide loans to farmers and make it compulsory for them to have insurance. With the loan, banks can pay the insurance on behalf of the farmers at the start of the season. But at the end of the season, the farmer has to repay the loan with interest. “The unit economics doesn’t work for us to work with farmers directly. But with banks, we know they provide loans to farmers with much better margins to pay for insurance. Also, we work together with government subsidy programs since they’re also interested in protecting their farmers.” Through its partnerships with banks, governments and agricultural input companies, Pula is at the center of an ecosystem that provides insurance to smallholder farmers and has amassed 50 insurance partners and six reinsurance partners. Its clientele includes the likes of the World Food Programme and Central Bank of Nigeria as well as the Zambian and Kenyan governments. Social enterprises like One Acre Fund, startups like Apollo Agriculture, and agribusiness giants like Flour Mills and Export Trading Group are also among Pula’s clients. Co-CEOs with agricultural backgrounds When Goslinga met Njeru in 2008, she worked for Syngenta Foundation for Sustainable Agriculture (SFSA). There, she started Kilimo Salama, as a micro-insurance program for more than 200,000 farmers in Kenya and Rwanda. She met Njeru who was the lead actuary at UAP Insurance, a partner to the Kilimo Salama program, at the time. After staying with Syngenta for six years and recognising the need to provide standard insurance products for smallholder farmers, Goslinga left to start Pula with Njeru in 2015. However, it wasn’t until two years later that Njeru joined fulltime as he had a six-year engagement with Deloitte South Africa from 2012 as a consultant actuary. The pair both act as co-CEOs. “When Thomas and I launched Pula in 2015, we had one goal in mind: to build and deliver scalable insurance solutions for Africa’s 700 million smallholder farmers,” Goslinga said. “With our latest funding, now is the time to break into new ground. In our five years since launching, we’ve built strong traction for our products. However, the fact remains that across Africa and other emerging markets, there are still millions of smallholder farmers with risks to their livelihoods that have not been covered.” According to Goslinga, the COVID-19 pandemic helped Pula double its footprint and size as rural farming activities and operations continued despite pandemic-induced lockdowns. Therefore, the new financing will scale up operations in its existing 13 markets across Africa, where it has insured over 4.3 million farmers. They include Senegal, Ghana, Mali, Nigeria, Ethiopia, Madagascar, Tanzania, Kenya, Rwanda, Uganda, Zambia, Malawi and Mozambique. Likewise, the Kenyan startup hopes to propel its expansion for smallholder farmers in Asia and Latin America. Pula is one of the few African startups disrupting the farming industry with technology. Its Series A investment attests that investors’ appetite for agritech startups is still on the rise. A week ago, Aerobotics, a South African startup that uses artificial intelligence to help farmers protect their trees and fruits from risks, raised a Series B round of $17 million. Last month, SunCulture, a Kenyan startup that provides solar power systems, water pumps and irrigation systems for small-scale farmers, raised $14 million. Another startup is Apollo Agriculture which raised $6 million Series A, akin to Pula. Not only did the pair raise the same round, Apollo Agriculture and Pula both deal with providing financial resources to smallholder farmers. But while both companies might look like competitors, even to the admission of Goslinga, she argues that the startups are partners and complement each other. As part of the new fundraise, TLcom’s senior partner Omobola Johnson will join Pula’s board. However, it was her colleague, Maurizio Caio, the firm’s managing partner, who had something to say about the round. “The potential for the insurance market for smallholder farmers in Africa is huge, and under the leadership of Rose and Thomas, Pula has rapidly established a strong presence throughout the continent and has several high-profile clients on their books. We are confident of Pula’s potential for growth in spite of the pandemic and look forward to partnering with them as they execute the next phase of their journey,” he said in a statement. For the lead investor, Pula’s investment marks the culmination of its busiest run of investments having led and co-led rounds in Okra, Shara, Autochek and Ilara Health within the past year. Christina Juhasz, CIO at Women’s World Banking, the other investor in the round, explained that the organisation cut a check for Pula “given the legions of women engaged in small-hold farming and securing the food supply for communities around the globe.” Source - https://techcrunch.com

Africa - Advances in modeling and sensors can help farmers and insurers manage risk

When drought caused devastating crop losses in Malawi in 2015-2016, farmers in the southeastern African nation did not initially fear for the worst: the government had purchased insurance for such a calamity. But millions of farmers remained unpaid for months because the insurer's model failed to detect the extent of the losses, and a subsequent model audit moved slowly. Quicker payments would have greatly reduced the shockwaves that rippled across the landlocked country. While the insurers fixed the issues resulting in that error, the incident remains a cautionary tale about the potential failures of agricultural index insurance, which seeks to help protect the livelihoods of millions of smallholder farmers across the globe. Recent advances in crop modeling and remote sensing—especially in the availability and use of high-resolution imagery from satellites that can pinpoint individual fields—is one tool insurers that can help improve the quality of index insurance for farmers, report a team of economists and earth system scientists this week in Nature Reviews Earth & Environment. "The enthusiasm for agricultural insurance needs to be matched with an equally well-founded concern for making sure that novel insurance products perform and help, not hurt, farmers exposed to severe risk," said Elinor Benami, the lead social scientist of the review. The review was co-led by Benami, an assistant professor in Agricultural and Applied Economics from Virginia Tech, and Zhenong Jin, an assistant professor of Digital Agriculture at the University of Minnesota, and included Aniruddha Ghosh from the Alliance of Bioversity International and CIAT. The authors outline opportunities for enhancing the quality of index insurance programs to increase the value that index insurance programs offer to agricultural households and communities. "Improvements in earth observation are enabling new approaches to assess agricultural losses, such as those resulting from adverse weather," said Zhenong. Index insurance in agriculture triggers payments when certain environmental conditions—seasonal rainfall, for example—stray from thresholds for a typical harvest. Unlike policies that require costly and time-consuming field visits to assess claims, index insurance uses an indicator of losses to cover a group of farmers within a given geographical area. This approach offers the promise of inexpensive, quick coverage to many people who would otherwise be uninsured. Lack of other types of coverage is due, in part, to the cost involved in verifying small claims on the ground. As the Malawi case shows, verification is also an issue for index insurance but its potential for scale, speed, and low cost render it viable for both insurers and desirable for farmers. When well matched to local experiences, index insurance can have meaningful impacts on agricultural livelihoods. One study cited by the authors found that people insured under a Kenyan index insurance program reduced their "painful coping strategies" by 40-80% when compared to uninsured households. In non-technical terms, "painful coping strategies" for smallholder households include skipping meals, removing children from school, and selling off what little productive assets they have. "Shocks that destroy incomes and assets have been shown to have irreversible consequences," said Michael Carter, a co-author of the review and an agricultural economist at the University of California, Davis. "Families never recover from the losses and become trapped in poverty. By restoring assets and income destroyed by shocks, insurance can halt this downward spiral before it starts. This can fundamentally alter the dynamics of poverty." Insurance has been shown to push the poverty needle in the other direction. By protecting assets after bad seasons, insurance payments also build the confidence farmers have to invest in their farms and progress toward better wellbeing, secure in the knowledge they will not need to pursue painful coping if bad times fall. Despite a few decades of experimentation with the idea of index insurance, however, serious quality issues have plagued implementation on the ground and place the otherwise promising concept of index insurance itself at risk. "With the technology of remote sensing changing rapidly, we wrote this review to call attention to the quality problem and to highlight ways to harness those technological advances to solve that problem. Our immodest hope is that this article will make more, high-quality insurance products available to small-scale farmers across the globe," said Carter. Better models, coverage Governments and insurers in sub-Saharan Africa have enrolled millions of farmers in index insurance programs. Programs have met with varying degrees of success and generally focus on livestock, in part because weather-related losses on rangelands are relatively easier to quantify. The authors say enhanced satellite imaging can potentially increase coverage and include more cropland. But improving the effectiveness of insurance is a bigger goal. "We're trying to encourage the insurance community to move towards not just how many people you have enrolled but how many people you protected well when they suffered," said Benami. To that end, the researchers discuss a minimum quality standard in their review, which is akin to a medical doctor's oath to patients: A minimum quality standard is based on the premise of doing no harm to farmers. Poor insurance coverage can make farmers worse off than they otherwise would have been without insurance. "The criteria that insurance regulators have told us that they want is good value for money—meaning that farmers get effective risk reduction and asset protection for the premia that are paid," said Benami. "As we understand it, insurers are looking for ways to reduce cost and encourage uptake while meeting regulatory requirements for their roll-out." To improve the quality, reliability, affordability and accessibility of index insurance, the authors make five concrete recommendations in their study. First, the full potential of higher-resolution spatial data and new data products on environmental conditions should be explored. Many possibilities exist to wring more value from satellite data for index insurance—such as pairing data from multiple sensors and or with crop models—and examining those possibilities is a promising opportunity to improve the match between observation and experience on the ground. Second, several opportunities exist to help improve loss detection. For example, this can be done with better crop modeling and new data products enabled by remote sensing, such as higher resolution soil moisture indicators of 100-meter resolution. Additional data sources such as drones and smartphones can be incorporated. Insurers should focus on metrics of farmer welfare as the key objective in insurance design. Third, better on-the-ground data will help bolster the usefulness and quality of insurance programs. Ground-referenced data is essential to evaluate how well a given index relates to a farmer's reality, and strategically collected data on environmental conditions, crop types, and yields for the areas considered by insurance would help diagnose and improve insurance quality. Fourth, insurance zones can be optimized to better reflect the geographic, microclimatic, and crop-management conditions that influence the productivity of specific landscapes. Within large administrative boundaries, considerable variation can occur due to mountains, rivers and different social customs. Finally, contracts can be designed to accommodate a variety of needs and the inevitability of index failure. Farmers have different needs and a rigid insurance contract window may not always reflect the times of the year a farmer is most concerned about risk as it relates to their production strategies and location. In addition, secondary mechanisms—liked audits—can be put into place to minimize uncompensated losses that can be missed by index errors. In implementing these recommendations, the Alliance's Ani Ghosh notes the importance of interdisciplinary, researcher-practitioner collaborations. For example, "the advances in economic, remote sensing, and crop modeling led by academic institutions complement CGIAR's experience in targeting, prioritizing, and scaling out interventions for smallholder farmers that can maximize the impact of index insurance programs," Ghosh said. "Overall, evaluating and designing programs to successfully manage risk is a problem with both technical and social dimensions," the authors conclude. "Although index insurance instruments will not solve all agricultural risk-related problems, they offer a useful form of protection against severe, community-wide shocks when done well."

Understanding disease-induced microbial shifts may reveal new crop management strategies

While humanity is facing the COVID-19 pandemic, the citrus industry is trying to manage its own devastating disease, Huanglongbing (HLB), also known as citrus greening disease. HLB is the most destructive citrus disease in the world. In the past decade, the disease has annihilated the Florida citrus industry, reducing orange production for juice and other products by 72%. Candidatus Liberibacter asiaticus (CLas) is the microbe associated with the disease. It resides in the phloem of the tree and, like many plant pathogens, is transmitted by insects during feeding events. Disease progression can be slow but catastrophic. Symptoms begin with blotchy leaves, yellow shoots, and stunting, and progress into yield decline, poor quality fruit, and eventually death. Currently, the only thing citrus growers can do to protect their crops from HLB is control the insect vector. Dozens of researchers are trying to find ways to manage the disease, using strategies ranging from pesticides to antibiotics to CLas-sniffing dogs. Understanding the plant microbiome, an exciting new frontier in plant disease management, is another strategy. Dr. Caroline Roper and first author Dr. Nichole Ginnan at the University of California, Riverside led a large research collaboration that sought to explore the microbiome's role in HLB disease progression. Their recent article in Phytobiomes Journal, "Disease-Induced Microbial Shifts in Citrus Indicate Microbiome-Derived Responses to Huanglongbing," moves beyond the single-snapshot view of the microbial landscape typical of microbiome research. Their holistic approach to studying plant-microbe interactions captured several snapshots across three years and three distinct tissue types (roots, stems, and leaves). What is so interesting about this research is the use of amplicon (16S and ITS) sequencing to capture the highly intricate and dynamic role of the microbiome (both bacterial and fungal) as it changes over the course of HLB disease progression. Ginnan et al. surmised that HLB created a diseased-induced shift of the tree's microbiome. Specifically, the researchers showed that as the disease progresses, the microbial diversity increases. They further investigated this trend to find that the increase in diversity was associated with an increase in putative pathogenic (disease-causing) and saprophytic (dead tissue-feeding) microbes. They observed a significant drop in beneficial microbes in the early phases of the disease. Arbuscular mycorrhizal fungi (AMF) were one such beneficial group that the authors highlighted as showing a drastic decline in relative abundance. The depletion of key microbial species during disease might be opening the door for other microbes to invade. Certain resources may become more or less available, allowing different microbes to prosper. Dr. Roper and Dr. Ginnan hypothesize that when HLB begins, this depletion event triggers a surge of beneficial microbes to come to the aid of the citrus tree. They suspect that the microbes are initiating an immune response to protect the host. As the disease proliferates, the citrus tree and its microbiome continue to change. Dr. Ginnan, the lead author on this study, found that there was an enrichment of parasitic and saprophytic microorganisms in severely diseased roots. The enrichment of these microbes may contribute to disease progression and root decline, one side effect of HLB. Survivor trees, or trees that did not progress into severe disease, had a unique microbial profile as well. These trees were enriched with putative symbiotic microbes like Lactobacillussp. and Aureobasidium sp. This discovery led the researchers to identify certain microbes that were associated with slower disease progression. Dr. Ginnan says their "aha" moment during the research was in the data analysis. "Originally we were looking for taxa that increased and decreased in relative abundance as disease rating increased," she said. "Our differential abundance analysis ended up revealing clear enrichment patterns replicated in multiple taxa." This is the moment they began to develop the individual patterns they were seeing into a broader disease model. This research is the foundation for future projects and collaborations that the authors are excited to continue to develop. They are motivated by the potential function of the microbiome to manage crop diseases. In the near future, they hope that these discoveries and an understanding of beneficial microbes can help establish a microbiome-mediated treatment plan to protect crops from diseases like HLB. In addition, the model they've developed can be applied to understanding diseases of other tree crop systems. Source - https://www.eurekalert.org

Canada - Sask. anticipates spending less on business risk programs

The Saskatchewan budget scheduled for March 18 turned out to be a non-event as the Legislature shut down amid COVID-19 concerns. Earlier that day the government announced a spending plan of $14.15 billion, but couldn’t say how much the virus will cost the health system or how much revenue the province could expect to take in. Finance minister Donna Harpauer said the province has access to $1.3 billion in cash if needed. Premier Scott Moe said the government would provide the funding needed to fight the pandemic. Cabinet will require special warrants to get money out of the door. Of the total, the agriculture ministry will see spending drop by $22 million or almost six percent to nearly $369 million. The major decrease comes in business risk management spending, which is always based on federal forecasts. The estimates project $15.8 million less spending for AgriStability and $15.9 million less on crop insurance premiums. Agriculture Minister David Marit said the federal forecasts were done in December. “It is important to note that business risk management spending is government by federal-provincial agreements and the amount that we spend in any one year is impacted by commodity prices and program participation,” he said through an emailed statement. “We recognize that the markets are very volatile and those spending forecasts will be adjusted through the year.” One area that will see some additional spending is irrigation development. Marit said $5 million will be used to conduct additional analysis of the potential, including a study of the Westside Irrigation and Qu’Appelle South Irrigation projects. Part of that work will include land identification and soil suitability assessments. “It is too early to indicate the costs required to build irrigation infrastructure,” he said. Marit added that investment from the federal government and the private sector would be required to develop the infrastructure. Source - https://www.producer.com

Managing frost damage on late-season corn for silage

Late corn plantings and cool autumn temperatures create a recipe for frost damage on corn grown for silage. The extent of the frost damage on the corn depends on the temperature, duration of the temperature, and corn growth stage at the time of the frost. Conditions for a frost Air temperatures below 32°F for four to five hours will result in frost damage to the stalk, leaf, and husk. Air temperatures that drop to 28°F for a few minutes and return to 32°F can result in similar injury. Air temperatures between 32°F and 40°F typically result in less frost damage. Frost at temperatures above 32°F usually occurs under conditions of clear skies, low humidity, and no wind. These conditions are ideal for rapid heat loss from the corn leaves. Under these conditions, temperature of the corn leaves can be less than the air temperature. Thin stands of corn and corn stands at the edges of fields are more likely to receive frost damage at temperatures above 32°F than thicker stands and the centers of fields. The uppermost leaves of the corn plant are most susceptible to frost damage at temperatures between 32°F and 40°F. Growth stage at time of frost Management of corn damaged by frost will depend on the stage of growth at the time of frost. Corn will ensile well at moisture levels less than 70% for upright silos and less than 75% moisture for horizontal silos. Corn harvested at 62% to 68% moisture (late-dent stage) is ideal for ensiling. Frost damage prior to the late-dent stage will result in corn that is too moist for silage harvest. Frost at these higher moistures will reduce yields and may reduce quality. Management of corn damaged by frost will depend on the stage of growth at the time of frost. (Photo: Courtesy of University Kentucky) Corn moisture content can be determined with a microwave or forage moisture tester. A simple field technique for determining corn moisture content is to squeeze a ball of chopped corn forage in your hand for 30 seconds. Release the ball of chopped forage and examine its shape. You can gain a rough estimate of moisture content based on the descriptions in Table 2. If you would prefer to not use the silage chopper to help determine whole plant moisture, then you can use a tobacco or corn knife to chop several corn plants. Be careful to chop up the corn plants into pieces that are similar in size to those cut by the silage chopper. Frost at Milk Stage When a frost occurs on corn at the milk stage, the moisture content of the plant is too high for proper ensiling. The leaves of the plant will dry very quickly, which causes the entire plant to appear to be drying more quickly. However, the entire plant will dry down similarly to corn that was not injured by frost. If the corn at milk stage is ensiled immediately after frost, then nutrients will leach away, the silage will be sour and wet, and livestock consumption will be low. Waiting to harvest frost-damaged corn at the milk stage will improve silage quality but will decrease dry matter yield. Up to 10% dry matter losses will occur the first 10 days after the frost, and up to 20% dry matter will be lost 40 days after the frost. In addition, mold may develop in the ears and cause further yield reductions. Because of these factors, a compromise between dry matter yield and ideal ensiling moisture must be made. In some cases, the corn will need to be harvested when it is too wet for silage. In these situations, chopped grain, hay, or straw can be added to the silage to decrease overall moisture. In general, 30 pounds of dry matter per ton of silage are required to reduce the moisture percentage by one point. For example, if the corn was at 78% moisture and the target moisture was 68%, then 300 pounds of dry matter would be required for each fresh ton of silage. One concern of frost occurring at the milk stage is high nitrate levels. High nitrate levels are toxic to cattle and will occur most frequently when the corn has been under drought stress prior to the frost. Ensiling will reduce nitrate levels 40% to 60%. To reduce the risk of nitrate toxicity, allow the ensiling process to occur for at least 21 days before feeding. See ID-86, Using Drought-Stressed Corn: Harvesting, Storage, Feeding, Pricing, and Marketing, for more information on nitrate levels in corn. Another option for corn with high moisture content is to feed the corn as green-chop. Cattle will consume less green-chop corn than ensiled corn. However, the quality of the frost-damaged, green-chopped corn is better than the quality of the ensiled corn at milk stage. If the corn is to be fed as green-chop, then check the corn for nitrate levels before feeding. A diagnostic test is available for determining nitrate levels, which is usually available through your county Extension office. Frost at Dough Stage If a frost occurs when the corn is at the dough stage, then whole corn is often too wet for silage harvest. Typically, several drying days are necessary before whole corn will be at the proper moisture for silage harvest. The corn should be harvested as soon as it reaches the desired moisture of 70% to 75%. The balance between waiting to harvest corn for silage at the ideal moisture and harvesting to prevent yield loss still must be considered. However, corn damaged by frost during the dough stage will require less time to dry down than corn damaged during the milk stage. If a frost occurs when corn is at the early dent stage, then whole corn may need to dry a couple days before it is ready to harvest. (Photo: Colleen Kottke/Wisconsin State Farmer) Frost at the Dent Stage If a frost occurs when corn is at the early dent stage, then whole corn may need to dry a couple days before it is ready to harvest. If a frost occurs when the corn is at the mid- to latedent stage, whole corn is at or very close to ideal moistures for ensiling. Corn damaged by frost at the mid- to late-dent stage should be harvested for silage immediately because whole plant moisture should be close to ideal for harvest and waiting to harvest could cause yield reductions. Summary Management of frost damage to corn grown for silage depends in part on the stage of growth when the frost occurred. Corn in the milk and dough stages is too wet for chopping and ensiling. The corn plants need to dry down before chopping occurs. Waiting to harvest frost-damaged corn will improve silage quality but will decrease dry matter yield. Producers must balance between expected yield losses and quality gains by waiting to harvest. Source - https://www.wisfarmer.com

New Zealand - Fans get to work as spring frosts threaten precious grapes

Vineyard frost fans have been doing their bit to protect one of Marlborough's biggest money spinners after a few cold starts in October. The fans, which pull warm air down onto the vines, are used when grapes start to bud - as a spring frost can lead to crop loss. Blenheim experienced four frosts in the first week of October, while all of October 2018 had only two frosts. But Marlborough Plant and Food research scientist Rob Agnew suspected frost fans would have been used more out in the Wairau Valley because of its colder climate. Villa Maria viticulturist Stuart Dudley said because Marlborough was a cool climate viticulture region there were definitely areas that were exposed to spring and autumn frosts. "The fans work by effectively bringing down warmer air," Dudley said. "It's called an inversion layer, effectively it's the same principle that is used by helicopters to protect the crops, but wind machines are a lot more reliable. "For us, as viticulturists, the wind machines are great, because if you get a forecast saying it might get to zero [degrees Celsius] and then you would have to toss up whether to spend the money on helicopters or not, whereas if you've got a frost fan the decision is already made, you just have to flick it on." Most were automatic, with a start temperature just above zero, but some grapegrowers had started switching from two-bladed fans to four or five, which were quieter, Dudley said. A Neighbourly poll showed 50 per cent of respondents who lived next to a vineyard were used to the sound. However, 17.3 per cent of respondents said they struggled to sleep at night because of the sound. Hawkesbury resident Nigel Taylor said noise from frost fans was something "you get used to". "You hear the two-bladed ones more than those with four or five," Taylor said. "You can definitely hear them but they don't interrupt us, you learn to live with it. "They're temperature-controlled so you notice when they turn off too, it's not a major disruption." Jenny King said rural residents knew living next to a vineyard could come with some noisy nights. "It's a small price to pay," King said. "It doesn't make for a great mood the next day but it's one of those things." King said she tended to hear the helicopter from the cherry orchards in Springlands more. Marlborough resident Ben Wallace said the fans were "minimally disruptive". "The benefits of frost fans for the local economy far outweigh the noise you have to put up with," he said. Source - https://www.stuff.co.nz

USA - Northern NY apple research tests hail netting as pest management[:ru]US

Real-time, regional, in-orchard research funded by the Northern New York Agricultural Development Program is helping apple growers quickly respond to pests with the latest management practices, the organization said. "Pest management is one of the largest investments fruit growers must make in terms of time, labor, and materials to produce marketable fruit and maintain healthy trees," says Michael Basedow, a tree fruit specialist with the Cornell Cooperative Extension Eastern NY Commercial Horticulture Program, Plattsburgh, N.Y. With a grant from the Northern New York Agricultural Development Program, Basedow provided weekly pest scouting data to help growers quickly respond to orchard pests with appropriate pest management tactics. He also initiated a project to evaluate whether exclusion netting used for protecting apple from hailstorm damage might also protect the fruit from orchard pests. A series of hailstorms in 2017 damaged the regional apple crop. One grower reported more than 60 percent of his acres suffered damage. Basedow says, "Growers selling hail-damaged fruit for juice that would otherwise have sold at retail prices can see as much as a 98 percent decrease in the economic value of their crop." Basedow worked with commercial growers in Clinton and Essex counties who had installed hail netting. Trials in France and Quebec, Canada, had shown success in limiting damage by codling moth and other orchard pests, but the use of drape-style netting had not been well-evaluated under northern NY orchard conditions.

Galimberti, CCE Clinton County, NY "We are constantly looking at ways to increase the use of integrated pest management practices that allow us to produce a commercially viable crop while also making the best use of growers' time, labor, and money. We wanted to see if the hail netting might be an effective practice to add to our apple growers' IPM toolbox," Basedow said. The research provided weekly trap data on four key apple pests in northern NY: codling moth, Oriental fruit moth, obliquebanded leafrooler, and apple maggot. "Results from the trial showed that traps in the trees under the netting caught significantly fewer of the four key pests compared to the unnetted trees, however," Basedow says, "the pest pressure levels in 2018 for three of the four key pests was such that the feasibility of using hail netting for pest exclusion is still uncertain. The netting may help reduce pest numbers enough to reduce the total number of orchard sprays needed for some pests, such as apple maggot, where spray decisions are based on well-established economic thresholds." Basedow adds that the sites with the most effective pest exclusion were those where the hail netting was tightly tied to the lower limbs and trunks of the apple trees. The orchard with the best control applied the netting to trees grown to a tall spindle training system with the netting secured tightly to the trunks. Source - https://www.freshplaza.com
