This study examines changes in frigate tuna populations in southern Sri Lanka, based on reports from fishers in three age classes. Significantly higher values for best day's catch and largest specimen ever caught were obtained by older fishers than younger ones. Values were also significantly hig...

This article presents findings of the action-research project on the what, why and how of 'multiple-use water services' or MUS, supported by the Challenge Program on Water and Food (active in 30 sites in 8 countries in Latin America, Africa and Asia). The consortium of partners from the domestic ...

The volume of wastewater generated by domestic, industrial and commercial sources has increased with population, urbanization, improved living conditions, and economic development. The productive use of wastewater has also increased, as millions of small-scale farmers in urban and peri-urban area...

Impact studies of catchment management in the developing world rarely include detailed hydrological components. Here, changes in the hydrological response of a 200-ha catchment in north Ethiopia are investigated. The management included various soil and water conservation measures such as the con...

Bean species and genotypes show wide phenotypic variability in relation to aluminium (Al) resistance and progressive soil drying. The objective of this study was to identify and characterize sources of resistance to Al toxicity and progressive soil drying among six genotypes of common bean (Phase...

The leaf-webber Spoladea recurvalis F. is the most devastating pest of amaranths in East Africa. Recent collaborative research in Asia and East Africa revealed one highly resistant amaranth accession (VI036227) to the pest and seven moderately resistant ones (RVI00053, VI033479, VI044437-A, VI047...

Compares the climates and soils and vegetation of the Ethiopian Rift Vallety with those of other areas in Africa, with particular reference to the screening of forage species. Examines the diversity of climates and soil conditions as they constitute constraints to forage or crop production in the...
