Background: In Addis Ababa, where irrigation water for vegetable production is commonly derived from the highly polluted Akaki river, information on microbial contamination of water and irrigated vegetable is scanty. An assessment was done to determine the microbiological quality of irrigation wa...

Reflecting on the food-energy nexus, my first thought went to the Haber–Bosch process. Perhaps no other human invention has had a more dramatic impact on our wellbeing and mother Earth than the Haber-Bosch chemistry. As the reader might know, and I am citing here largely from Wikipedia, the Haber...

The supply response of the smallholder soybean growers was investigation using a sample of 307 farmers randomly-selected from Jive villages in Kaduna and Kano States of Nigeria. Different multivariate functional forms were experimented but the power Junction was chosen because of its obvious uniq...

Land provides a host of ecosystem services, of which the provisioning services are often considered paramount. As the demand for agricultural products multiplies, other ecosystem services are being degraded or lost entirely. Finding a sustainable trade-off between food production and one or more ...

Water storage is crucial for water security (WS) in countries with monsoon-driven climates. Tanks significantly contribute to WS by augmenting water supply to agricultural production in parts of south and Southeast Asia. The present paper assesses the potential locations of small tanks for rehabi...

Reduced river runoff and expected upstream infrastructural developments are both potential threats to irrigation water availability for the downstream countries in Central Asia. Although it has been recurrently mentioned that a reduction in water supply will hamper irrigation in the downstream co...

Soil moisture is a highly suitable indicator for assessing agricultural drought, as plants start to wilt when there is not sufficient soil water to meet evapotranspiration demand. In this study, we provide insights on information obtained from satellite surface soil moisture observations (as comp...

The attainment of food and water security rank high on the agendas of governments in the Middle East and North Africa (MENA) region and sub-Saharan Africa (SSA). Although the objectives are similar, the underlying drivers, resource endowments and opportunities for achieving them are different. Di...

Large-scale agricultural land investments in Africa are often considered solely from the land perspective. Yet land, water and other natural resources are closely interlinked in agricultural production and in sustaining rural livelihoods. Such investments involving irrigation will potentially hav...
