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]
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.
Holdridge life zone classification scheme. Although conceived as three-dimensional by its originator, it is usually shown as a two-dimensional array of hexagons in a triangular frame. Map of the world using hexagons of the same area, with landmasses and oceans categorized as different Lifezones, also arranged hexagonally
A shift of 1 or 100% (darker colours) indicates that the region has fully moved into a completely different biome zone type. [1] Climate change is already now altering biomes, adversely affecting terrestrial and marine ecosystems. [2] [3] Climate change represents long-term changes in temperature and average weather patterns.
A 2021 report from the Intergovernmental Panel on Climate Change found that the rise in greenhouse gases has led to more severe extreme weather. Now, Joyner is among several advocates hoping to ...
Drylands are zones where precipitation is balanced by evaporation from surfaces and by transpiration by plants (evapotranspiration). [1] The United Nations Environment Program defines drylands as tropical and temperate areas with an aridity index of less than 0.65. [2] One can classify drylands into four sub-types: Dry sub-humid lands; Semi ...
In a world where the climate is increasingly hot and volatile, farmers are having trouble keeping their crops cool. A startup founded in the desert of Saudi Arabia thinks it might have a solution.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
