A review of gender equality and social inclusion issues in Zambia’s agribusiness ecosystem
(International Institute of Tropical Agriculture, 2024-08) -
Performance of IITA developed cassava postharvest technologies
(1991)The paper describes the package of postharvest equipment for processing Cassava into various forms of food products. Field performance features are presented in terms of effect on system efficiency and some measurable socio-economic impact. Technology development strategies derived from the fie ld testing are discussed. -
A survey of aflatoxin and aflasafe awareness and management among Nigerian poultry producers and feed millers
(Purdue University, 2017-06)Aflatoxin is a potent mycotoxin that can cause cancer, stunted growth, and (in extreme instances) rapid death. Aflatoxin can contaminate many staple crops, including maize and groundnuts. As many as 4.5 billion people in the developing world may be chronically exposed. Scientists at the United States Department of Agriculture – Agricultural Resource Service, International Institute of Tropical Agriculture (IITA), and African Agricultural Technology Foundation have developed a biological control ... -
“We’re in this together”: Changing intra-household decision making for more cooperative smallholder farming
(2016-01-29)Conceptualising smallholder farming households as collective action institutions, that make interrelated decisions about investment, resource use and allocation in a common household farm, may contribute to understanding widely observed uncooperative outcomes, such as yield gaps, gender gaps in productivity, suboptimal or Pareto inefficient sustainable intensification and climate change adaptation. We examine the relation between participatory intra-household decision making – as a set of ‘rules ... -
Climate change adaptation in agriculture: Ex ante analysis of promising and alternative crop technologies using DSSAT and IMPACT
(2015)Achieving and maintaining global food security is challenged by changes in population, income, and climate, among other drivers. Assessing these challenges and possible solutions over the coming decades requires a rigorous multidisciplinary approach. To answer this challenge, the International Food Policy Research Institute (IFPRI) has developed a system of linked simulation models of global agriculture to do long-run scenario analysis of the effects of climate change and various adaptation ... -
Collaborative Study of Cassava in Africa (COSCA); site selection procedure: COSCA working paper, No. 2
(1989)This paper describes the methods of site selection used for a village-level survey which comprised the first phase of the Collaborative Study of Cassava in Africa (COSCA). Potential survey regions are defined using spatial data which describe ecological conditions, human population densities, accessibility, and the distribution of cassava production. Sixteen different types of regions are identified. Methods are described for selecting random samples of grid cells in each survey region, and for ... -
Collaborative Study of Cassava in Africa (COSCA); project description: COSCA working paper, No. 1
(1988)COSCA was initiated through the realization that the potentials of cassava depends on availability of more detailed and reliable information on the cassava crop. The general objective of COSCA is therefore to improve the relevance and impact of agricultural research on cassava by International Agricultural Research Centres and National Agricultural Research Systems in Africa in order to take full advantage of. the potentials of cassava in increasing food production and incomes of poor people. COSCA ... -
COSCA project description: COSCA working paper, No. 1
(1988)The general objective of the Collaborative Study of Cassava in Africa (COSCA) is, to improve the relevance and impact of agricultural research on cassava by international agricultural research centres (!ARC) and national agricultural research systems (NARS) in Africa in order to take full advantage of the potential of cassava in increasing food production and incomes in Africa. The countries participating are Cote d'lvoire, Ghana, Nigeria, Zaire, Uganda and Tanzania. The major consideration in the ... -
Systems analysis in AIS: potentials and pitfalls
(Royal Tropical Institute, 2017)Agricultural innovation systems are complex, multi-layered, and can be difficult to define and analyse. In this paper, we provide examples of ‘systems analysis’: describing the context, what was done, and how the outcomes informed broader research and development activities. The five cases describe analyses of: i) agricultural systems in North-West Vietnam; ii) household food security in Central Vietnam; iii) agricultural innovation systems in Central Africa; iv) wheat commodity systems in Sub-Saharan ... -
The importance of banana (Musa sp) for food and nutrition security

Stimulating agricultural technology adoption lessons from fertilizer use among Ugandan potato farmers
(International Food Policy Research Institute, 2017-02)In the context of a growing population in an already densely populated area, agricultural yields will need to increase without putting additional stress on the environment. The adoption of modern inputs by smallholders is an important ingredient of agricultural transformation. In this study we explore plot-level, household-level, and institutional-level characteristics associated with agricultural technology adoption behavior among smallholder farmers. The aim is to uncover correlations that can ... -
Economy-wide impacts of promising maize and wheat technologies on food security and welfare in Kenya
(2016-06)A recursive dynamic economy-wide model incorporating productivity changes due to the introduction of promising maize and wheat varieties evaluates foresights for future food security, well-being and economic performance in Kenya. Adoption of promising new maize and wheat varieties not only increases overall economic growth and food availability, it also reduces import dependency and increases the welfare of vulnerable populations, especially rural households in lowland regions. Although maize-producing ... -
A CGE analysis of the implications of technological change in Indian agriculture
(Partnership for Economic Policy (PEP), 2016-06)A recursive dynamic computable general equilibrium (CGE) model is used to conduct an exante analysis of the economy-wide impacts of new agricultural technologies in India. Differential impacts of changes in productivity of new promising cultivars for irrigated and rainfed maize and wheat are incorporated in the model. Technological change in these crops results in higher future economic growth as well as food security, both in food consumption and availability. While there is considerable scope ...
