Grazing can have positive or negative effects on rangeland health, depending on management quality, [128] and grazing can have different effects on different soils [129] and different plant communities. [130] Grazing can sometimes reduce, and other times increase, biodiversity of grassland ecosystems.
Earth offers enough room to plant an additional 0.9 billion ha of tree canopy cover. [4] Planting and protecting them would sequester 205 billion tons of carbon [4] which is about 20 years of current global carbon emissions. [5] This level of sequestration would represent about 25% of the atmosphere's current carbon pool. [4]
Different Asian Countries have various effects from climate change. China , for example, benefits from a 1.5 °C (2.7 °F) temperature increase scenario accompanying with carbon fertilization and leading to a 3% gain of US$18 billion per year; however, India will face two thirds of the continent's aggregate losses on agriculture because its ...
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]
Assisted migration is the act of moving plants or animals to a different habitat. The destination habitat may or may not have once previously held the species. The only requirement is the destination habitat must provide the bioclimatic requirements to support the species. Assisted migration aims to remove the species from a threatening ...
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.
Both agricultural plants and animals depend on pollination for reproduction. Vegetables and fruits are an important diet for human beings and depend on pollination. Whenever there is habitat destruction, pollination is reduced and crop yield as well. Many plants also rely on animals and most especially those that eat fruit for seed dispersal.
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [83] It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.
