Livestock and crop-livestock systems are usually more complex than single cropping systems and are thus more difficult to "improve". The International Livestock Centre for Africa outlines experiences with systems research in projects in Nigeria and in the Ethiopian highlands.

This study examines the socioeconomic features that underpin the expansion of groundwater-dependent irrigation in Northern State, Sudan. Groundwater development in the region serves as an economic lifeline given the poor Nile-based irrigation infrastructure and future changes in Nile hydrology. G...

Irrigated agriculture in Jordan's highlands relies on overexploited groundwater. Drops in water tables and water quality, but also tougher policy measures by the government, threaten the sustainability of this activity which has long thrived on lax law enforcement and cheap desert land. This pape...

In the short term, grazing of a 40-ha fallow in the Sahel, Niger, by sheep and goats reduced the standing herbage mass in the wet season and increased its disappearance during the dry season. The effects of stocking rate (62.5 or 125 k g liveweight/ha) and the proportion of sheep in the mixture (...

Drechsel, PayHanjra, Munir A.[Wastewater for agriculture, forestry and aquaculture - Section iv]Wastewater for agriculture, forestry and aquaculture - Section iv

Increase in salinity levels poses a threat to many hot and arid farming areas in the Middle East and North Africa region. In some cases, farmers install desalination units to produce freshwater to irrigate high-value crops. However, the produced reject brine is an environmental hazard since it is...
