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]
Dryland farming caused a large dust storm in parts of Eastern Washington on October 4, 2009. Courtesy: NASA/GSFC, MODIS Rapid Response [1]. Dryland farming has evolved as a set of techniques and management practices to adapt to limited availability of water, as in the Western US and other regions affected by climate change for crops such as tomato and maize.
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
Fukuoka was the author of several books, scientific papers and other publications, and was featured in television documentaries and interviews from the 1970s onwards. [7] His influences went beyond farming to inspire individuals within the natural food and lifestyle movements. He was an outspoken advocate of the value of observing nature's ...
The regolith profiles of badlands in arid climates are likely to resemble one another. In these regions, the upper layer (~1–5 cm or 0.4–2.0 in) is typically composed of silt, shale, and sand (a byproduct of the weathered shale). This layer can form either a compact crust or a looser, more irregular aggregation of "popcorn" fragments.
The most populated coastal regions of Peru are the two parallel mountain ranges and the series of 20 to 30 rivers descending through its coastal desert. In dry periods only the mountains had enough rainfall for agriculture while the desert coast was empty. In wet periods many cultures thrived along the rivers.
Soil-conservation farming involves no-till farming, "green manures" and other soil-enhancing practices which make it hard for the soils to be equalized. Such farming methods attempt to mimic the biology of barren lands. They can revive damaged soil, minimize erosion, encourage plant growth, eliminate the use of nitrogen fertilizer or fungicide ...
Desert landscape in Libya; 90% of the country is desert. Although agriculture is the second-largest sector in the economy, Libya depends on imports in most foods. Climatic conditions and poor soils limit farm output, and domestic food production meets about 25% of demand.
