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 effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7] Therefore, the native vegetation may become more vulnerable to damage. [8]
Tree-planting campaigns are criticised for sometimes targeting areas where forests would not naturally occur, such as grassland and savanna biomes. [ 7 ] [ 64 ] [ 65 ] Carbon sequestration forecasts of afforestation programmes often insufficiently consider possible carbon reductions in soils as well as slowing tree growth over time.
A paloverde tree acting as a nurse plant to a saguaro in the Sonoran Desert not far from the Superstition mountains. A nurse plant is one that serves the ecological role of helping seedlings establish themselves, and of protecting young plants from harsh conditions. This effect is particularly well studied among plant communities in xeric ...
Predicated changes for Earth's biomes under two different climate change scenarios for 2081–2100. Top row is low emissions scenario, bottom row is high emissions scenario. Biomes are classified with Holdridge life zones system. A shift of 1 or 100% (darker colours) indicates that the region has fully moved into a completely different biome ...
Xeric shrublands can experience woody plant encroachment, which is the thickening of bushes and shrubs at the expense of grasses. [5] This process is often caused by unsustainable land management practices, such as overgrazing and fire suppression, but can also be a consequence of climate change.
NEOM green Hydrogen plant is based in Oxagon a city in NEOM, Saudi Arabia that was created as a port city but is entirely floating, on the coast of the Red Sea and runs entirely on clean energy . The NEOM Green Hydrogen plant was launched in 2021 and aims for net zero emissions by 2060. [22] The First Saudi Environment Week
The predicted outcome of global warming in this subtropical region, is the reduction of plant/animal productivity and growth. Another effect would be that the increase of climate warming would also lead to tree mortality affecting not only the pine trees located in the Sierra Madre Occidental but also other pine trees in the surrounding areas.
