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]
The US National Research Council assessed the literature on the effects of climate change on crop yields in 2011, [28] and provided central estimates for key crops. [ 28 ] : 160 A meta-analysis in 2014 revealed consensus that yield is expected to decrease in the second half of the century, and with greater effect in tropical than temperate regions.
The idea of soil loss tolerance was initially devised by the SCS (known presently as the NRCS). It was based on the minimum soil loss rate required to reduce organic content and harm crop productivity. In its early stages of development, soil loss tolerance rates were inconsistent because they were obtained based on rough estimates.
The concept of combination phenomics comes from the idea that two or more plant stresses have common physiological effects or common traits - which are an indicator of overall plant health. [ 12 ] [ 13 ] [ 14 ] As both biotic and abiotic stresses can result in similar physiological consequence, drought resistant plants can be separated from ...
The effects stem from the altered hydrological conditions caused by the installation and operation of the irrigation scheme. Amongst some of these problems is the depletion of underground aquifers through overdrafting. Soil can be over-irrigated due to poor distribution uniformity or management wastes water, chemicals, and may lead to water ...
Nitrogen deposition from air pollutants and increased mineralization from higher temperatures can increase plant productivity, but increases are often among a discount in biodiversity as faster-growing plants outcompete others. A study of a California grassland found that global change may speed reductions in diversity and forb species are most ...
Tolerance is the ability of plants to mitigate the negative fitness effects caused by herbivory. It is one of the general plant defense strategies against herbivores , the other being resistance , which is the ability of plants to prevent damage (Strauss and Agrawal 1999).
Soil regeneration is the reformation of degraded soil through biological, chemical, and or physical processes. [ 2 ] When productivity declined in the low-clay soils of northern Thailand, farmers initially responded by adding organic matter from termite mounds , but this was unsustainable in the long-term.
