Are Kenyan farmers under-utilizing fertilizer? Implications for input intensification strategies and research

It is widely perceived that African farmers are under-utilizing inorganic fertilizer. However, very little long-term evidence from farmers’ fields, accounting for variations in agro-ecological conditions, has been assembled to back this claim or determine the conditions under which it is true. Using five waves of nationwide household survey data from Kenya covering 13 years, we estimate the relative and absolute profitability of nitrogen application rates on maize fields and compare these profitability conditions to observed nitrogen use patterns over time. In general, we find that farmers are consistently and steadily increasing towards risk-adjusted economically optimal rates of fertilizer application over time and that, in the most agriculturally productive areas, farmers’ application rates on maize sometimes exceed rates that maximize profitability. Fertilizer use rates may nevertheless be profitably raised in these areas, but doing so will require the adoption of complementary inputs and management practices that raise maize response rates to fertilizer application. This motivates a more holistic approach to input intensification strategies in the region.     

Supermarket contracts and smallholder farmers: Implications for income and multidimensional poverty

Food systems in developing countries are changing rapidly with a growing role of modern supermarkets. Supermarkets influence supply chains and the way agricultural products are sourced from farmers. Especially for the procurement of fresh fruits and vegetables, supermarkets often contract farmers directly to ensure consistent and high-quality supply. One important question, which is addressed here, is whether smallholder farmers benefit from supermarket contracts. Previous studies address this question, but mostly focus on income effects without exploring implications for other dimensions of household welfare, such as nutrition, health, or housing conditions. Moreover, most existing studies rely on cross-section data. We add to the literature by analyzing effects of supermarket contracts on income and multidimensional poverty using three rounds of panel data collected from smallholder vegetable farmers in Kenya and econometric models with household fixed effects. On average, supermarket contracts increase household income by over 40%. We also find significant reductions in income poverty and multidimensional poverty. Quantile regressions show that farmers in all income groups benefit, but richer households benefit more than poorer ones in absolute terms. However, supermarket contracts cause the strongest reductions in multidimensional deprivations among the poorest households.     

Productive efficiency of specialty and conventional coffee farmers in Costa Rica: Accounting for technological heterogeneity and self-selection

A steep decline in coffee prices at the producer level led to considerable pressure for farmers in Costa Rica and producer countries all over the world. One possible reaction was moving to specialty markets, where price pressure was perceived to be lower. We use original survey data from 2002/2003 and 2003/2004 to analyze the factors influencing participation in specialty markets and to estimate separate production functions for specialty and conventional coffee farmers allowing for farm-specific inefficiencies. Applying a sample selection framework, we find significant selection bias in the sub-sample of specialty farmers and evidence for the overestimation of efficiency, if this bias is not adequately controlled for. Among the most important factors that influence farm-specific efficiency levels in the two sub-samples are the availability of additional income activities, experience in coffee cultivation, and membership in cooperatives. Based on the results, we derive policy recommendations to improve farmers’ production performance and ability to cope with the effects of the coffee crisis. These policy measures include the provision of extension services with respect to farm management skills, the creation of income opportunities in rural areas, and the support of farmer-owned cooperatives.     

More theory,in theory

An important aspect of the milk and dairy industry in the European Community is the reaction of milk producers to milk prices. In theory farmers behave like the economic man of basic economic textbooks. In practice, farmers behave quite differently, ie they increase their production when prices fall. For policy makers in the field of dairy products it is essential to know the reaction of the farming industry. Surprisingly this information is not available in the EEC; there are various opinions and estimates but they are heavily disputed. However, we now have the results of a study which can settle the dispute.¹ It is interesting to see the results and to notice that there really is a fundamental problem involved, ie how to discriminate between economic models.     

Understanding farmers’ valuation of agricultural insurance: Evidence from Vietnam

Agricultural index insurance offers smallholder farmers the potential to manage pervasive weather and environmental risks, and smooth income over time. Yet despite the potential benefits, take-up of index insurance has been largely disappointing. We employ a novel approach to investigate the reasons for low demand and we confirm that farmers systematically undervalue agricultural index insurance. We find that access to private transfers acts as a substitute for insurance demand, while membership of a farmer’s union helps explain why farmers value index insurance. Finally, we find that individual riskiness is positively related to willingness to pay for agricultural index insurance and interpret this as further evidence that, within the context of basis risk and lack of trust in insurers, farmers valuation of agricultural index insurance can be better understood through behavioural theories such as ambiguity aversion or prospect theory.     

Knowing is half the battle: Seasonal forecasts,adaptive cropping systems,and the mediating role of private markets in Zambia

This paper examines how smallholders living in regions where a drought is forecasted adapt their farm practices in response to receiving seasonal forecast information. The article draws on a unique longitudinal dataset in Zambia, which collected information from farm households before and after a significant drought caused by the 2015/2016 El-Niño Southern Oscillation. It finds that farmers residing in areas forecasted to be drought-affected and receiving seasonal forecast information are significantly more likely to integrate drought tolerant crops into their cropping systems compared to similar households not receiving this information. Moreover, the probability that a farmer implements these adaptive farm management strategies in response to seasonal forecast information is found to increase substantially as the number of private grain buyers in the farmers’ village increases. This suggests that climate change adaptation and resilience strategies that integrate the generation and dissemination of weather information with agricultural market development can achieve greater impact on farmers’ adaptive responses than approaches that treat these activities in isolation.     

Awareness of ag-gag laws erodes trust in farmers and increases support for animal welfare regulations

Hidden-camera investigations are becoming an increasingly popular means of raising public awareness about farm animal welfare. However, livestock industries claim they are deceptive. One strategy to curtail these investigations has been the introduction of so-called ag-gag legislation, which aims to restrict the flow of information coming out of farm facilities. Psychological research suggests that this approach may be counter-productive as reducing information flow often reduces feelings of trust. We sought to extend these findings by applying them to a real-world, timely example and to determine whether the perceived intention to obstruct access to information erodes feelings of trust. Accordingly, this study tested whether simply being made aware of ag-gag laws might have a negative impact on trust in farmers. Participants (n = 716) were randomly assigned to either receive information about ag-gag laws or to a Control condition. We found that most people were unaware of ag-gag laws and that learning about them lead to a decrease in trust in farmers and an increase in support for animal welfare regulations. Interestingly, we also found evidence that awareness of ag-gag laws negatively impacted perceptions of the current status of farm animal welfare as well as the perception that farmers do a good job of protecting the environment. Through this topical example, this study demonstrates that even the intention to restrict access to information can undermine trust.     

New agricultural technology and smallfarmers in Latin America

Biased income distribution in agriculture as a result of the green revolution towards better agricultural regions and larger farmers has been justified by declining prices for rice and wheat making consumers the main beneficiaries of this new technology. But, there are two arguments for focusing future agricultural technology towards small farmers and poorer resource regions. First, evidence suggests that there is little productivity or nutritional improvement from migration. Second, unless the supply of prime areas can be made more elastic, most of the small farmer food crops, even with new technology, will not be sufficiently profitable to displace the high value activities currently found in these areas in Latin America.     

Exploring double side-selling in cooperatives,case study of four coffee cooperatives in Rwanda

Apart from the difficulty to attract new members, leakage of sales outside the cooperative is a major challenge for the coffee cooperatives in Rwanda. Local (independent) traders still constitute a major market for coffee producers. Yet, cooperatives also accept the produce from non-members and pay them the same price. Our objective in this paper is to analyse the importance of this phenomenon of double side-selling. We collected data from a sample of 170 coffee farmers. We use a probit model to analyse characteristics linked to cooperative membership and to study double side-selling. We describe the trade relationships between farmers and the cooperative on the one hand, and between farmers and traders on the other by the attributes of transaction costs involved in the trade of coffee. Membership characteristics include easy access to labour, land tenure, risk aversion, and mutual trust between farmers and cooperatives’ management. Preference to sell to traders can be explained by the trust farmers seem to have in them after the repeated transactions in credit and basic consumption items and by long-term relationships in the community.     

WTO negotiations on agriculture and the distributional impacts for US rice farm households

The policies of wealthy countries have proven the most difficult to reform in the WTO Doha Round negotiations. Considerable emphasis has been placed on developing country impacts, but a gap in the literature remains on the stakes for rich country farmers despite the large role these countries play in global agricultural protection. The research here considers the particular case of US rice households and their sensitivity to Japanese market access reform. Using an applied general equilibrium model with multiple farm households we highlight the distributional impacts among these producers. We argue that concessions to Japan on market access make domestic reforms in rice a difficult political sale in the US since the wealthiest producers bear the largest losses. Improving our understanding of the distributional impacts and political realities of the richest countries is critical to informing the negotiating process because the gains to the world’s poor can only be realized with creative policy redress in these rich nations.     

Farmers’ preferences for supermarket contracts in Kenya

With the modernization of global agri-food systems, the role of contract farming increases. This also involves smallholder farmers in developing countries. While previous studies have looked at economic impacts of contract schemes on smallholder farmers, little is known about farmers’ preferences for contracting in general, and for specific contract design attributes in particular. Better understanding farmers’ preferences and constraints is important to make smallholder contract schemes more viable and beneficial. This article builds on a choice experiment to analyze farmers’ preferences and preference heterogeneity for contracts in Kenya. In the study region, supermarkets use contracts to source fresh vegetables directly from preferred suppliers. However, farmer dropout rates are high. Mixed logit models are estimated to examine farmers’ attitudes towards critical contract design attributes. Having to deliver their harvest to urban supermarkets is costly; hence farmers require a significant output price premium. Farmers also dislike delayed payments that are commonplace in contract schemes. The most problematic contract attribute is related to unpredictable product rejection rates, substantially adding to farmers’ risk. Designing contracts with lower transaction costs, more transparent quality grading, and fairer risk-sharing arrangements could enhance smallholder participation in supermarket procurement channels.     

Do lower yielding farmers benefit from Bt corn? Evidence from instrumental variable quantile regressions

There have been serious questions about whether lower-yielding farmers in developing countries, who are typically poor smallholders, benefit from genetically-modified crops like Bacillus thuringensis (Bt) corn. This article examines this issue by estimating the heterogeneous impacts of Bt corn adoption at different points of the yield distribution using farm-level survey data from the Philippines. A recently developed estimation technique called instrumental variable quantile regression (IVQR) is used to assess the heterogeneous yield effects of Bt corn adoption and at the same time address potential selection bias that usually plague impact assessment of agricultural technologies. We find that the positive yield impact of Bt corn in the Philippines tend to be more strongly felt by farmers at the lower end of the yield distribution. This result suggests that Bt corn could be a “pro-poor” technology since most of the lower-yielding farmers in the Philippines are poor smallholders with low incomes.

Impact of metal silos on households’ maize storage,storage losses and food security: An application of a propensity score matching

Maize is the most important food staple in Eastern and Southern Africa, with a highly seasonal production but relatively constant consumption over the year. Farmers have to store maize to bridge seasons, for food security and to protect against price fluctuations. However, the traditional storage methods do not protect grain well, resulting in large postharvest losses. Hermetically sealed metal silos kill storage pests by oxygen deprivation without pesticides. Popular in Central America, they are now being promoted in Africa, but their impact here has not yet been studied. This study used propensity score matching to evaluate the impact of metal silos on duration of maize storage, loss abatement, cost of storage, and household food security. Metal silo adopters (N = 116) were matched with non-adopting farmers from a representative sample of 1340 households covering the major maize-growing zones in Kenya. The major effect of the metal silos was an almost complete elimination of losses due to insect pests, saving farmers an average of 150–200 kg of grain, worth KSh9750 (US$130). Metal silo adopters also spent about KSh340 less on storage insecticides. Adopters were able to store their maize for 1.8–2.4 months longer, and to sell their surplus after five months at good prices, instead of having to sell right after the harvest. The period of inadequate food provision among adopters was reduced by more than one month. We conclude that metal silos are effective in reducing grain losses due to maize-storage insects, and that they have a large impact on the welfare and food security of farm households. The initial cost of metal silos is high (KSh20,000/1.8 ton) and therefore policies to increase access to credit, to reduce the cost of sheet metal, and to promote collective action can improve their uptake by smallholder farmers.     

Implications for food production, land use and rural development of the European Union’s Single Farm Payment: Indications from a survey of farmers’ intentions in Germany, Portugal and the UK

The 2003 reform of the European Union’s (EU) Common Agricultural Policy introduced a decoupled income support for farmers called the Single Farm Payment (SFP). Concerns were raised about possible future land use and production changes and their impact on rural communities. Here, such concerns are considered against the workings of the SFP in three EU Member States. Various quantitative studies that have determined the likely impact of the SFP within the EU and the study countries are reviewed. We present the results of a farm survey conducted in the study countries in which farmers’ responses to a decoupling scenario similar to the SFP were sought. We found that little short-term change was proposed in the three, rather different, study countries with only 30% of the farmers stating that they would alter their mix of farm activities. Furthermore, less than 30% of all respondents in each country would idle any land under decoupling. Of those who would adopt a new activity, the most popular choices were forestry, woodland and non-food crops.     

Improving the efficiency targeting of Malawi's farm input subsidy programme: Big pain,small gain?

The Farm Input Subsidy Programme (FISP) in Malawi was introduced in the 2005/2006 season against a background of bad weather affecting production and prolonged food shortages. Vouchers are distributed empowering eligible farmers to exchange them for fixed quantities of inputs at subsidized prices. Since its inception, there has been a debate at national level about whether the FISP’s potential has been fully exploited, with policy makers exploring options to improve the programme. Proposals include targeting efficient and productive farmers to maximize returns. In this paper, we evaluate the effectiveness of these proposed changes to the existing FISP design by utilizing two waves of the LSMS-ISA survey merged with climatic data. We estimate how the national demand for agricultural inputs varies according to a variation in the targeting criteria by means of a two-stage demand system. Then, we identify more efficient farmers by means of a stochastic frontier approach. We observe a mismatch between voucher recipients and efficiency, with approximately 60% of vouchers being allocated to the three bottom quintiles of efficiency. This mismatch is observed also at the spatial level with more vouchers going to districts characterized by less efficient production. While concerns on the distributional impacts of the new criteria are discussed together with some suggestions for spatially diversifying the structuring of the policy and incentivizing crop diversification, our results highlight a high substitutability of commercial with subsidized inputs by new eligible farmers. Consequently, simulating the targeting policy variation we obtain an outcome that would lead only to a limited increases in predicted food expenditure ranging from 0.27% to 0.8% and maize production from 0.2% to 1.3. Scope for analysing different adjustments in the functioning of FISP are, thus, proposed to policy makers.     

Can biotechnology reach the poor? The adequacy of information and seed delivery

The paper examines the expectation that biotechnology can provide significant benefits for smallholder farmers. It uses evidence from current seed systems and variety choice in developing countries. In particular, it examines the adequacy of information flow and the performance of seed markets. Many of the biotechnology innovations proposed for use by smallholders feature qualities that may not be immediately obvious to farmers; implications are drawn for the potential demand for these transgenic varieties. The adequacy of seed systems is also examined, including the characteristics of local seed diffusion and the experience of commercial seed enterprises. The paper concludes that investments in public biotechnology must be accompanied by policies that encourage commercial seed system development and that empower farmers to be able to take full advantage of new technology.     

Genes to feed the world: The weakest link?

The new science of genomics has an important contribution to make to the development of agriculture in the ‘Third World’ and thus to improving the livelihoods of many of the poorest people on earth. The persistence of poverty demonstrates, however, that this contribution is not yet being made. We therefore examine the web of connections between the two and enquire whether they could be strengthened in some way, perhaps by the addition of some vital ‘missing link’, so that the contribution from genomics can be maximised. Since the use of molecular markers to help develop improved crop varieties (marker-assisted selection) constitutes one of the main ways in which genomic knowledge could be used to improve rural livelihoods, we review this technology and discuss the ways in which it could contribute to plant breeding. We argue that marker-assisted selection (MAS) is likely to be most effective when it is both (i) linked to the farmers who are expected to cultivate the new crop varieties that will eventually be developed; and (ii) integrated with plant breeding and with a range of complementary disciplines. Such integration necessarily involves the formation of effective trans-disciplinary teams, an undertaking that is often problematic, and so the final part of this article considers the processes that this involves and suggests ways in which they may be managed effectively.     

Targeting agricultural research and extension for food security and poverty alleviation: A case study of fish farming in Central Cameroon

Over 5 years of participatory on-farm research, market access, profitability, farming systems productivity and economic sustainability were compared on 100 small-scale farms in Central Cameroon. Integration technology based on the use of agricultural by-products as fishpond inputs was the driver for intensification. Over all farms, fishpond productivity increased from 498 kg to 1609 kg fish/ha (2145 kg/ha/yr). During the project period, the number of active fish farmers increased from 15 to 192 (including 55 farms which participated only through information exchange). Over all farms, net returns from aquaculture increased by 5 times over pre-project levels. Productivity, intensity and profitability increased more significantly in periurban areas with good market access, compared to rural areas. Among farmers with good market access, average net income from the aquaculture enterprise rose from $118 up to $1485. Research-Extension Team (RET) support cost an average of $61,300 per year. Over 5 years, rural farmers recaptured 23% of the relevant RET investment compared to 442% by periurban farmers. Likewise, increase in production attributable to RET intervention was higher for periurban (253%) compared to rural (11.3%) fish farmers. Within 3 years of the end of extension support, rural farmers had returned to pre-project production levels, whereas periurban farms had better maintained their productivity and profitability. Findings indicate that, in areas with little or no access to markets, the number of fishponds and fish farmers can be increased and yields improved, increasing local food supplies, but sustainability in the absence of extension subsidies is questionable. To achieve either of the two principal goals for the sector, food security and/or poverty alleviation, investments need to be made in improving the availability of quality technical assistance to targeted farmers and finding means of reducing social conflict arising from perceived inequalities in the accrual of the benefits of development.
