The Government of Kenya (GoK) has historically encouraged its farmers to use fertilizer by financing infrastructure and supporting fertilizer markets. From 1974 to 1984, the GoK provided a fertilizer importation monopoly to one firm, the Kenya Farmers Association. However, the GoK saw that this monopoly impeded fertilizer market development by prohibiting competing firms from entering the market and, in the latter half of the 1980s, encouraged other firms to enter the highly regulated fertilizer market. This report examines the state of fertilizer use in Kenya by reviewing and summarizing literature on recent fertilizer price increases, Kenya’s fertilizer usage trends and approaches, market forces, and the impact of government and non-government programs. We find that most studies of Kenya’s fertilizer market find it to be well functioning and generally competitive, and conclude that market reform has stimulated fertilizer use mainly by improving farmers’ access to the input through the expansion of private retail networks. Overall fertilizer consumption in Kenya has increased steadily since 1980, and fertilizer use among smallholders is among the highest in Sub-Saharan Africa. Yet fertilizer consumption is still limited, especially on cereal crops, and in areas where agroecological conditions create greater risks and lower returns to fertilizer use.
Farmers in Sub-Saharan Africa (SSA) use less fertilizer than farmers in any other region in the world. Low fertilizer use is one factor explaining the lag in agricultural productivity growth in Africa. A variety of market interventions to increase fertilizer use have been attempted over the years, with limited success. In the past several decades, Malawi has tried to alter that trend through a variety of innovative programs aimed at achieving national food security through targeted input subsidy programs. The best known of these programs is Malawi’s Starter Pack Programme. The Starter Pack Programme was amended twice into the Targeted Inputs Programme (TIP) and Expanded Targeted Inputs Programme (ETIP), and eventually replaced with the Agricultural Input Subsidy Programme (AISP). The efficiency and equity of the Starter Pack Programme and its successors have been the subject of debate. This report reviews the history, implementation, and perceived effectiveness of the various input subsidy schemes in the context of Malawi’s political economy. We find that AISP is credited with significantly increasing maize yields in Malawi. However, we also find that there are serious challenges facing the most recent input subsidy program, ranging from the rising cost of the subsidy to ongoing implementation struggles related to increased bureaucracy and corruption.
Lack of nitrogen (N) is often cited as the most limiting factor in agriculture. Although N composes nearly 80% of the atmosphere, plants are unable to use this form of the element (N2) because of the strong triple bonds between the two atoms. Nitrogen deficiency is especially problematic in the soils of Sub-Saharan Africa (SSA). Low levels of N and other soil fertility problems have severe poverty, malnutrition and environmental degradation consequences for SSA. The process by which atmospheric N2 is converted into N compounds that can be used by living things is called nitrogen fixation. Biological nitrogen fixation (BNF or biofixation) offers an alternative or additional means to traditional nitrogen fixation to increase plant-available nitrogen. Through a symbiotic relationship, an N-fixing bacterium infects a plant (usually a legume) and forms nodules on the roots of the plant in which N fixation occurs. This literature review examines the expansion and benefits of BNF, the constraints to BNF adoption, BNF regulations, and success stories of developing and distributing BNF technologies worldwide. BNF technology can be an efficient and effective tool for decreasing environmental degradation and increasing soil fertility, yields, income, and food security in SSA, although many constraints to farmer adoption exist.
Presentation slides summarizing agriculture growth and development information sourced from the World Development Report and two academic papers provided by the Bill and Melinda Gates Foundation. Slides convey information in a non-academic format. Slides are organized into: agricultural pro-poor growth, agriculture as an engine for development, who benefits from agriculture, and the effects and policy impacts of the Green Revolution.
