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.
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.
The Sahara Desert features a hot desert climate (Köppen climate classification BWh).The Sahara Desert is one of the driest and hottest regions of the world, with a mean temperature sometimes over 30 °C (86 °F) and the average high temperatures in summer are over 40 °C (104 °F) for months at a time, and can even soar to 47 °C (117 °F).
The Mojave Desert Land Trust is working to scout, catalogue, collect and preserve millions of seeds from 250 species and counting in a race to save an ecosystem.
The heat stress and die-offs observed in recent years is enough to make horticulturalists like Schilling reconsider what they thought they knew about desert ecosystems.
The World Wide Fund for Nature highlights a number of desert ecoregions that have a high degree of biodiversity and endemism: [1] 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 monument — with Sáttítla referring to the volcanic ecosystem and obsidian flows found in the area — will protect a region that McDaniels calls “a natural buffer to climate change ...
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] Today, the Imperial Valley in southern California, Australia, Saudi Arabia, and Israel are examples of modern desert agriculture. Water efficiency has been important to the growth of ...
