Arid-zone agriculture, or desert agriculture, is the subject of research and development that includes studies of how to increase the agricultural productivity of lands dominated by a lack of fresh water, an abundance of heat and sunlight, and usually one or more of the following: Extreme winter cold, short rainy season, saline soil or water ...
Aridification is the process of a region becoming increasingly arid, or dry.It refers to long term change, [1] rather than seasonal variation. It is often measured as the reduction of average soil moisture content.
Desert farming is the practice of developing agriculture in deserts. As agriculture depends upon irrigation and water supply, farming in arid regions where water is scarce is a challenge. However, desert farming has been practiced by humans for thousands of years. In the Negev, there is evidence to suggest agriculture as far back as 5000 BC. [1]
Agriculture in Arizona is a notable sector in the state's economy, contributing more than $23.3 billion in 2018. Arizona's diverse climate allows it to export all sorts of commodities such as nuts, wheat, cotton, eggs, meat, and dairy to the United States and 70 other countries.
Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
Precision Agriculture: The use of GPS and GIS for meticulous field management, with variable rate technology allowing tailored application of resources, optimizing output while minimizing resources.
Regions with hot semi-arid climates Semi-arid climate in Queensland, Australia. Hot semi-arid climates (type "BSh") tend to be located from the high teens to mid-30s latitudes of the tropics and subtropics, typically in proximity to regions with a tropical savanna climate or a humid subtropical climate. These climates tend to have hot, or ...
where is the mean annual net radiation (also known as the net radiation balance), is the mean annual precipitation, and is the latent heat of vaporization for water. Note that this index is dimensionless and that the variables R {\displaystyle R} , L {\displaystyle L} and P {\displaystyle P} can be expressed in any system of units that is self ...
