Cereal production around the world is critical to the food supply for the human population. Crop productivity is primarily determined by a combination of temperature and precipitation because temperatures have to be in the range for plant growth and precipitation has to supply crop water requirements for a given environment. The question is often asked about the changes in productivity and what...

Agricultural drought is the leading cause for crop failure throughout the world. In the USA, significant impacts of recent droughts on agricultural production indicate the continuing vulnerability of the country to drought. This paper presents a methodology for spatial representation of the agroclimatic component of agricultural drought vulnerability. This methodology was developed as a part of...

Livestock farming is a livelihood activity and critically important for the food nutritional security of majority population in West African countries, including Senegal. Nevertheless, livestock operates far below optimum production potential, mainly due to demographical, biophysical, economic, environmental, sociopolitical challenges. To address these issues, we conducted this review with an o...

Droughts can cause devastating impacts on water and land resources therefore monitoring these events forms an integral part of planning. The most common approach for detecting drought assessing their intensity is use the Standardized Precipitation Index (SPI), which requires abundant precipitation records at good spatial distribution. This may restrict SPI usage in many regions around world, pa...
