This paper presents an approach for assessing the effectiveness of projects aimed at creating incentives for smallholder farmers to continue maintaining crop diversity under evolution on their farms in relevant centers of genetic diversity—a process known as on-farm conservation. It is applied to...

The association between serum antibody titres to Theileria parva in calves and potential explanatory factors were examined in a longitudinal observational study that was conducted in 5 cohorts of female calves with a total of 225 calves on 188 smallholder dairy farms. The farms were distributed i...

Globally, 38% of the land area is agricultural land, of which 45% are located on drylands, mainly in Africa and Asia, constituting the basis for about 60% of the world’s food production. Of all farms worldwide, 83% are smallholder farm systems, whose livelihoods depend on effective land managemen...

A serious game to uncover dynamics in farm land allocation at household level in northern Ghana

Agricultural intensification involving greater crop-livestock interactions and integration is emerging as the most promising strategy for improving agricultural production and productivity in much of sub-Saharan Africa. In West Africa, where this process is at various stages of evolution, 559 far...

Reports the productivity levels achieved by grade Boran cattle maintained by chemoprophylaxis at Mkwaja ranch (Tanzania) from 1973 to 1982. Analyses the effects of year and season of calving on birth, cow age, calf sex and area & location of herd on performance of the environmental influences. Ev...

Genetic erosion of domestic animal diversity has placed 30% of the world's breeds at risk of extinction, often as a result of government policy/programmes. Conservation and sustainable development of animal genetic resources (AnGR) require a broad focus that includes the many 'adaptive' breeds th...
