Two critical factors that explain low crop productivity in the Sahelian agro-ecozone are inadequate
moisture and poor soils, particularly phosphorus (P) deficiency. The purpose of this long-term study
was to explore the use of both local phosphate rock (PR) and inorganic P on yields and risk of...

Use of rainfall indices to analyze the effects of phosphate rocks on millet in the Sahel
Most climate change scenarios predict a significant increase in the frequency of high intensity rainfall events especially in the dry areas, which will increase runoff and soil erosion. Understanding the factors that control soil erosion is crucial to recommending appropriate measures to protect ...

Storing excess rainwater underground can become key in mitigating the frequency and magnitude of flood events. In this context, assessment of depleted groundwater storage that can be refilled in water surplus periods is imperative. The study uses Gravity Recovery and Climate Experiment (GRACE) da...

This paper evaluates 30-year (2013–2042) projections of the selected climatic parameters in cotton/wheat agro-climatic zone of Pakistan. A statistical bias correction procedure was adopted to eliminate the systematic errors in output of three selected general circulationmodels (GCM) under A2 emis...

Agriculture is a major occupation for people who inhabit the state of West Bengal in India. In order to boost irrigation, 570 tube wells per year were installed during 2002-2008, and 12,000 wells per year were installed during 2009-2013, contributing to higher groundwater (GW) withdrawal. However...

Background: Farmers apply several and often different farmer-specific strategies to cope with and adapt to the perceived trend of declining rainfall and crop productivity. A better understanding of the factors affecting farmers’ coping and adaptation strategies to counteract both trends is crucia...

Groundwater is an important resource for multiple uses in South Africa. Hence, setting limits to its sustainable abstraction while assuring basic human needs is required. Due to prevalent data scarcity related to groundwater replenishment, which is the traditional basis for estimating groundwater...

This paper ilustrates the principle determining cropping systems for Vertisols by reviewing work in the highlands of Ethiopia. The types of cropping systems that can be applicable in the different Vertisol environments are briefly described. These cropping systems include single cropping; multipl...
