  2. Desert ecology - Wikipedia

    en.wikipedia.org/wiki/Desert_ecology

    The harsh climate of most desert regions is a major obstacle in conducting research into these ecosystems. In the environments requiring special adaptations to survive, it is often difficult or even impossible for researchers to spend extended periods of time investigating the ecology of such regions.

    The Nama Karoo of Namibia has the world's richest desert fauna. [8] The Chihuahuan desert and Central Mexican matorral are the richest deserts in the Neotropics. [9] The Carnarvon xeric shrublands of Australia are a regional center for endemism. [1] The Sonoran and Baja deserts of Mexico are unusual desert communities dominated by giant ...

  4. Drylands - Wikipedia

    en.wikipedia.org/wiki/Drylands

    The livelihoods of millions of people in developing countries depend highly on dryland biodiversity to ensure their food security and their well-being. Drylands, unlike more humid biomes, rely mostly on above ground water runoff for redistribution of water, and almost all their water redistribution occurs on the surface. [4]

    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.

    Traditional desert farming systems have long been established in North Africa, irrigation being the key to success in an area where water stress is a limiting factor to growth. Techniques that can be used include drip irrigation , the use of organic residues or animal manures as fertilisers and other traditional agricultural management practices.

    The Sahara Desert is the world's largest hot, non-polar desert and is located in North Africa. It extends from the Atlantic Ocean in the west to the Red Sea in the east, and from the Mediterranean Sea in the north to the Sahel savanna in the south. [2] The vast desert encompasses several ecologically distinct regions.

  9. Ecosystem diversity - Wikipedia

    According to a study, there are over 50 plants that are dependent on bee pollination, many of these being key staples to feeding the world. [12] Another study conducted states that a lack of plant diversity will lead to a decline in the bee population fitness, and a low bee colony fitness has impacts on the fitness of plant ecosystem diversity ...
