Priority regions for research on dryland cereals and legumes

Journal Articles & Books
Mai, 2016

Dryland cereals and legumes are important crops in farming systems across the world. Yet they are frequently neglected among the priorities for international agricultural research and development, often due to lack of information on their magnitude and extent. Given what we know about the global distribution of dryland cereals and legumes, what regions should be high priority for research and development to improve livelihoods and food security? This research evaluated the geographic dimensions of these crops and the farming systems where they are found worldwide.

Plant breeding and the nutritive value of crop residues. Proceedings of a workshop

Conference Papers & Reports
Décembre, 1988

Presents papers dealing with the use of crop residues as livestock feed in smallholder crop/livestock farming systems, and the role of plant breeding in maintaining or improving their nutritive value. Discusses factors limiting the nutritive value of crop residues, and the effect of genotype and environment on the nutritive value of crop residues. Outlines perspectives and implications for crop improvement programmes. Includes recommendations.

Potential environmental impacts

Journal Articles & Books
Décembre, 1992

As the problems of impact assessement are rather intractable, a fairly simple dual approach is proposed. First the major components of environmental impact of current agricultural production systems in Africa (i.e. impact of cropping, livestock keeping, fuelwood and timber extraction and burning) are summarised. Second, "danger zones" in which current and future environmental impacts will be most severe and on which ILCA has focused its problem solving-research is identified.

Irrigation scheme performance assessment is vital to evaluate the impacts of irrigation practices, to identify performance gaps and to improve system performances. However, the performance of Jari and Aloma Small Scale Irrigation (SSI) schemes was not assessed since its operation. Therefore, this study was carried out to evaluate the water delivery, on-farm water management and organizational performances of the two SSI schemes.

Overview of G3: Water Governance and Community Based Management

Décembre, 2012

The International Water Management Institute is the lead institute for the Ganges Basin Development Challenge research project titled Water Governance and community-based management in coastal regions of Bangladesh. This study is one out of five research projects in the Ganges basin commissioned and funded by the CGIAR challenge Program on Food and Water inundation, salinity intrusion and severe flooding in the coastal areas is a frequent occurrence in Bangladesh. This leads to loss of life and property as well as severe impacts on livelihoods.
