This book was released on 2016-04-01 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The imbalanced application of chemical fertilizers in India is widely blamed for low yields, poor soil health, pollution of water resources, and large public expenditures on subsidies. To address the issue, the government of India is investing in a large-scale, expensive program of individualizedsoil testing and customized fertilizer recommendations, with the hope that scientific information will lead farmers to optimize the fertilizer mix. We conducted a randomized controlled trial in the Indian state of Bihar in what we believe to be the first evaluation of the effectiveness of the program as currently implemented. We found no evidence of any impact of soil testing and customized fertilizer recommendations on actual fertilizer use or the willingness to pay for lacking nutrients (elicited using aBecker-DeGroot-Marschak mechanism). Several factors could be driving these results, including a lack of understanding, lack of confidence in the information’s reliability, or the costs of the recommended fertilizer mixes.

This book was released on 2019-01-25 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of fertilizers that do not meet the nutrient requirements (i.e. balanced nutrient application) of target crops is a widespread problem in India. Farmers overuse urea (N) and seldom apply secondary nutrients (Sulphur, Calcium, and Magnesium) and micro-nutrients (like Zinc, Iron, Copper, Boron, Molybdenum and Manganese) in their plots. This imbalanced application of nutrients affects both long-term health of the soil as well as farmers’ own net incomes from agriculture. How do we deploy scientific research, business innovations, and public policies and programs to help promote balanced use of fertilizers in Indian agriculture?

Download or read book Understanding compliance in programs promoting conservation agriculture written by Ward, Patrick S. and published by Intl Food Policy Res Inst. This book was released on 2016-05-13 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land degradation and soil erosion have emerged as serious challenges to smallholder farmers throughout southern Africa. To combat these challenges, conservation agriculture (CA) is widely promoted as a sustainable package of agricultural practices. Despite the many potential benefits of CA, however, adoption remains low. Yet relatively little is known about the decision-making process in choosing to adopt CA. This article attempts to fill this important knowledge gap by studying CA adoption in southern Malawi. Unlike what is implicitly assumed when these packages of practices are introduced, farmers view adoption as a series of independent decisions rather than a single decision. Yet the adoption decisions are not wholly independent. We find strong evidence of interrelated decisions, particularly among mulching crop residues and practicing zero tillage, suggesting that mulching residues and intercropping or rotating with legumes introduces a multiplier effect on the adoption of zero tillage.

This book was released on 2021-06-28 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lack of accurate information about soil nutrient requirements coupled with limited access to appropriate fertilizers could lead to mismatch between soil nutrient requirements and fertilizer applications. Such anomalies and mismatches are likely to have important implications for agricultural productivity. In this paper we use experimental (spectral soil analysis) data from Ethiopia to examine farmers’ response to soil nutrient deficiencies and its implications for yield responses. We find that farmers’ response to macronutrient (nitrogen and phosphorus) deficiencies is not always consistent with agronomic recommendations. For instance, we find that farmers in our sample are applying nitrogen fertilizers to soils lacking phosphorus, potentially due to lack of information on soil nutrient deficiencies or lack of access to appropriate fertilizers in rural markets. On the other hand, farmers respond to perceivably poor-quality soils and acidic soils by applying higher amount of nitrogen and phosphorus fertilizers per unit of land. We further show that such mismatches between fertilizer applications and soil macronutrient requirements are potentially yield-reducing. Those farmers matching their soil nutrient requirements and fertilizer application are likely to enjoy additional yield gains and the vice versa. Marginal yield responses associated with nitrogen (phosphorus) application increases with soil nitrogen (phosphorus) deficiency. Similarly, we find that farmers’ response to acidic soils is not yield-enhancing. These findings suggest that such mismatches may explain heterogeneities in marginal returns to chemical fertilizers and the observed low adoption rates of chemical fertilizers in sub-Saharan Africa. As such, these findings have important implications for improving input management practices and fertilizer diffusion strategies.

This book was released on 2016-04-29 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adoption of machinery in agricultural production in Africa south of the Sahara has been far behind the level of mechanization found in Asia and Latin America. However, recent survey data have revealed high levels of machinery use in localized areas of cereal production in northern Ghana. A survey conducted by the International Food Policy Research Institute, in partnership with the Savannah Agriculture Research Institute, found that in some areas more than 80 percent of farmers were using machinery for at least one operation. This paper considers the theoretical drivers of agricultural intensification, as outlined by Boserup, Pingali, and Binswanger, and the extent to which they are able to explain the spatial variation in machinery use found in northern Ghana. Population pressure, market access, and agroecological conditions are considered key drivers that cause farmers to find ways to increase productivity and adopt new technologies. Combining survey data with geospatial datasets, the empirical analysis finds that population growth and travel time to the local urban center explain a significant and large proportion of the variation in machinery use by farmers.

This book was released on 2016-04-20 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an increasing demand to add pulses to the basket of subsidized goods in the Public Distribution System (PDS) of India—the world’s largest food-based social safety-net program. Would subsidizing pulses through PDS lead to a significant increase in its consumption? We study the case of subsidy on pulses in select Indian states and its impact on consumption and ultimately nutrition (in terms of protein intake) by exploiting an exogenous variation in prices to answer this question. Between 2004/2005 and 2009/2010, four Indian states introduced subsidized pulses through the country’s PDS, while other states did not. We exploit exogenous price variations to examine whether the price subsidy on pulses achieves its goal of increasing pulse consumption, and by extension protein intake, among India’s poor. Using several rounds of consumption expenditure survey data and difference-in-difference estimation, we find that the change in consumption of pulses due to the PDS subsidy, though statistically significant, is of a small order, and not large enough to meet the goal of enhancing the nutrition of beneficiaries.

This book was released on 2016-05-03 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: When an outbreak of an infectious disease is suspected, a local health agency may notify a state or federal agency and request additional resources to investigate and, if necessary, contain it. However, due to capacity constraints, state and federal health agencies may not be able to grant all such requests, which may give an incentive to local agencies to request help strategically. We study a model of detection and control of an infectious disease by local health agencies in the presence of imperfect information about the likelihood of an outbreak and limited diagnostic capacity. When diagnostic capacity is rationed based on reports of symptoms, the decision to report symptoms or not creates a trade-off. On the one hand, rigorous testing allows one to make an informed disease control decision. On the other hand, it also increases the probability that the disease will spread from an untested area where fewer precautionary measures are taken. Symptoms are overreported (respectively, reported truthfully, or underreported) when the cost of disease control is sufficiently small (respectively, in some intermediate range, or sufficiently large). If the disease incidence decreases or infectiousness increases, symptoms are reported less frequently. If the precision of private signals increases, the extent of overreporting of symptoms may increase. For different values of the parameters it can be socially optimal to subsidize or tax requests for additional investigations and confirmatory testing.

Download or read book Long term drivers of food and nutrition security written by Laborde Debucquet, David and published by Intl Food Policy Res Inst. This book was released on 2016-05-18 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2015 Global Hunger Index suggests that despite progress in reducing hunger worldwide, hunger levels in 52 of 117 countries in the 2015 Global Hunger Index remain “serious” or “alarming.” Since achieving and maintaining food and nutrition security (FNS) remains a goal for all countries, it is important to understand the individual, national, and global factors that affect FNS. This paper proposes an analytical framework to identify and analyze the respective roles of key long-term drivers of FNS. We start by identifying what the key variables affecting FNS are at the household and country level, and then we continue by defining what the main exogenous or endogenous drivers affecting these variables are. We discuss the key drivers of both aggregated food supply and demand and therefore their impact on prices. Specifically, for aggregated food demand, we discuss demographic factors, income growth, changes in dietary preferences, aggregated domestic distortions, and overall quality of the food system. With respect to the drivers of aggregated food supply, we discuss land available for food products and the drivers behind land availability, the share of waste/losses generated by the food system, and the normalized average yield. We define yield as the amount of nutrients produced by unit of land. It depends both on the physical yield of the crop or the livestock and on the quality of the food produced. It also can be affected by the changes in production patterns linked to the different dietary patterns of the consumers and by climate change. We emphasize the fact that in many cases, key drivers may have ambiguous effects on the FNS situation of different agents. For instance, more liberal trade policies will affect real income, terms of trade, demand and supply, returns of factors, foreign direct investments, and food prices and thus may lead to the improvement of the global-level FNS, that is, the FNS of the majority of the population. At the same time, more liberal trade policies may bring food insecurity to some households. Therefore, careful quantitative assessment is needed for each policy option. Finally, we propose a typology of variables that will help modelers adapt their models to study the different drivers through both direct and indirect effects.

This book was released on 2016-05-27 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rise of mixed methods approaches to development-oriented research has brought new attention to qualitative research methods. This paper describes the use of qualitative approaches to illuminate gender relations in agricultural development research and project implementation. For gender research, qualitative methods can be particularly helpful in illuminating how men and women view their lives. Drawing on literature about social science methods and linking it to recent examples of qualitative methods employed in research and development projects, the paper argues for greater precision in key concepts of gender research, starting with sex and gender. From the many possible qualitative methods used in development work, the paper focuses on several common observational (both direct and participatory) and interview techniques, the latter including key informant and group interviews and focus group discussions. Researchers use various techniques to gather different types of information, for example, mapping techniques to understand men’s and women’s different types of knowledge about their environment and eliciting in-depth information on a single topic with key informants. In a brief discussion of the analysis of qualitative data, the paper notes that informant responses are not “the truth” but need to be assessed against other sources of data. Finally, there is a short discussion of how qualitative data have been used in comparative work. The paper concludes that the results of good qualitative research on gender relations can help identify the locally specific pathways needed to achieve gender-transformative development approaches.

Download or read book Can labor market imperfections explain changes in the inverse farm size productivity relationship written by Deininger, Klaus and published by Intl Food Policy Res Inst. This book was released on 2016-06-24 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand whether and how inverse relationship between farm size and productivity changes when labor market performance improves, we use large national farm panel from India covering a quarter-century (1982, 1999, 2008) to show that the inverserelationship weakened significantly over time, despite an increase in the dispersion of farm sizes. A key reason was the substitution of capital for labor in response to nonagricultural labor demand. In addition, family labor wasmore efficient than hired labor in the 1982–1999 period, but not during the 1999–2008period.In line with labor market imperfections as a key factor, separability of labor supply and demand decisions cannot be rejected in the second period,except in villages with very low nonagricultural labor demand.

This book was released on 2016-04-29 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A renewed focus on agriculture’s potential contribution to economic transformation in Africa has resulted in increased attention paid to agricultural mechanization. African agriculture still relies predominantly on human muscle power despite anecdotal evidence on urbanization and rising rural wages, in contrast to other developing regions that have experienced rapid increases in agricultural mechanization during the past few decades. Past state-led mechanization pushes in Africa often failed due to insufficient understanding of the nature of demand for mechanization technologies among farmers and insufficient knowledge of private-sector functions. This background paper reviews the factors likely to influence farmer demand for mechanization in Africa and details different existing and potential mechanization supply models. Although an empirical analysis of mechanization demand and the effectiveness of supply chains is beyond the scope of this paper, in part due to data limitations, this paper suggests that demand for mechanization may be emerging in some parts of Africa. It also suggests that private-sector-driven supply models are better positioned to meet this demand than direct government involvement and certain types of subsidized programs. The paper then identifies possible areas for government support to complement private-sector leadership in developing mechanization supply chains. Nevertheless, significant further research is required to better understand the changing nature of mechanization demand in Africa and the extent and effectiveness of different supply models in meeting it.

This book was released on 2016-04-20 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explores the evolution of real agricultural wages, machinery use, and the relationship between farm size and productivity in Vietnam during its dramatic structural transformation over the course of the 1990s and 2000s. Using six rounds of nationally representative household survey data, we find strong evidence that the inverse relationship between rice productivity and planting area attenuated significantly over this period and that the attenuation was most pronounced in areas with higher real wages. This pattern is also associated with sharp increases in machinery use, indicating a scale-biased substitution effect between machinery and labor. The results suggest that rural-factor market failures are receding in importance, making land concentration less of a cause of concern for aggregate food production.

Download or read book Risk and sustainable crop intensification written by Van Campenhout, Bjorn and published by Intl Food Policy Res Inst. This book was released on 2016-04-15 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: To feed a growing and increasingly urbanized population, Uganda needs to increase crop production without further exhausting available resources. Therefore, smallholder farmers are encouraged to adopt sustainable crop intensification methods such as inorganic fertilizer or hybrid seeds. However, these farmers perceive these new technologies as risky hence adoption will depend on how well they can manage this additional risk. This paper documents patterns observed in socioeconomic data that suggest risk is an important barrier to sustainable crop intensification practices among Ugandan smallholder rice and potato farmers. In particular, we find that households that engage in risk management strategies, such as investing in risk-reducing technology or engaging in precautionary savings, are more likely to practice intensified cropping. However, our data also show only limited yield risk associated with the use of fertilizers or pesticides, suggesting part of the problem is related to perception. We also discuss the consequences for policy.

This book was released on 2016-04-21 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the decision of a firm that sells an experience good to delegate quality control to an independent monitor. In an infinitely repeated game consumers’ trust provides incentives to (1) acquire information about whether the good is defective and (2) withhold the good from sale if it is defective. If third-party reports are observable to consumers, delegation of monitoring lessens the first and dispenses with the second moral hazard concern but also creates agency costs due to either limited liability or lack of commitment. In equilibrium the firm controls quality without an independent monitor only if trades are sufficiently frequent and consumer information about quality is sufficiently precise. This result holds under different assumptions about feasible contracts, collusion, verifiability of reports, joint inspections, and the number of firms that hire the third-party monitor. If third-party reports are not publicly observed, delegation can be optimal only if two or more firms hire the third-party monitor because then both moral hazard concerns are present under delegation.

Download or read book Can contract farming increase farmers income and enhance adoption of food safety practices written by Kumar, Anjani and published by Intl Food Policy Res Inst. This book was released on 2016-04-20 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing inequality has become an important concern in many countries. One of the ways that inequality is perpetuated is through differential market access across regions. This research deals with one of the primary determinants of regional inequality manifested in terms of market access. Nepal is one country where hierarchical geography leads to regional inequality. Differential market access can cause as well as accentuate inequality among farmers. Coordination arrangements such as contract farming can improve outcomes for the farmers and integrators on the one hand, but on the other hand it can accentuate inequality if only some regions benefit from it. With this background, in this paper we study the case of contract farming for exports with farmers in remote hilly areas of Nepal. The prospect for contract farming in such areas with accessibility issues owing to underdeveloped markets and lack of amenities is ambiguous. On the one hand, contractors in these areas find it difficult to build links, particularly when final consumers have quality and safety requirements. On the other hand, remoteness can make the contracts more sustainable if the agroecology offers product-specific quality advantages and, more important, if there is a lack of side-selling opportunities. At the same time, concerns remain about buyers’ monopsonistic powers when remotely located small farmers do not have outside options. This study hence quantifies the benefits of contract farming on remotely located farmers’ income and compliance with food safety measures. Results show that contract farming is significantly more profitable (offering a 58 percent greater net income) than independent production, the main pathway being higher price realization, along with training on practices and provision of quality seeds.
