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.

Sustainable agricultural practices enable more efficient use of natural resources, mitigate the impact of agriculture on the environment, and strengthen capacity for adaptation to climate change and climate variability. Because these practices usually require substantial effort or resource allocation from farmers, incentives are necessary to support farmer adoption. Despite growing interest, there has been little systematic evaluation of the incentives–adoption–outcome chain—that is, which incentives best promote adoption and which lead to desired sustainability outcomes. This brief presents the results of a literature review that examined (1) uptake agricultural practices under three kinds of incentives, market and nonmarket, regulations, and cross-compliance, and (2) the impact on productivity, profitability, and environmental sustainability. Based on this review, it offers a set of seven tested principles to follow in designing and implementing incentives for sustainable agriculture.

The primary goal of the study is to investigate the potential to expand oilseeds, specifically soybeans,as an alternative commercialcrop to tobacco among Malawian farmers. A principal motivation for undertaking the study at the microeconomic level is to determine, in a theoretically consistent fashion, the type of policy and economic environment under which farmers begin to shift more of their scarce resources to oilseed production.The study aims to provide recommendations to a growing demand among policy makers and development partners for a greater diversification of exports and crop production systems of the majority smallholder farmers in Malawi. Using representative farm models, the study examinesthe potential for expanding production of soybeans among typical smallholder farming systems in Malawi. The results will help guide future policies and investments targeted at promoting greater crop diversification and incomes, in order to reduce poverty and malnutrition in Malawi. Given the amount of labor and land resources allocated to maize production for food security purposes, we also consider the policy challenges that emerge for crop diversification as a result

Ghana’s Fertilizer Subsidy Programme (GFSP) was initiated in 2008 in response to the global food and fuel price crisis. Although initially intended to be a temporary measure that became increasingly expensive as Ghana’s macroeconomy deteriorated, farmers, civil society organizations, and politicians began to expect the subsidy on an annual basis. This paper applies the kaleidoscope model for agricultur and food security policy change to the case of GFSP. In doing so, it uses a variety of analytical tools to highlight how many of the weak outcomes of GFSP can be attributed to the nature of the broader policy process that has surrounded GFSP as well as the underlying political and institutional context in which policy making occurs in Ghana. Based on semi-structured interviews conducted with knowledgeable stakeholders spanning the government, donor, civil society, and research communities, the paper identifies the bottlenecks that need to be addressed if the program is to be more effective in the future.
