Despite the fact that food is a big climate problem, very little has been done so far to address it. This year's U.N. climate conference in Dubai will be the first to dedicate a whole day to the ...
The salt level is often taken as the soil salinity or the salinity of the irrigation water. Salt tolerance is of importance in irrigated lands in (semi)arid regions where the soil salinity problem can be extensive as a result of the salinization occurring here. It concerns hundreds of millions of hectares. [2]
International Center for Biosaline Agriculture (ICBA) is an international, not-for-profit applied agricultural research center with a unique focus on marginal environments. [1] It identifies, tests and introduces resource-efficient, climate-smart crops and technologies that are best suited to different regions affected by salinity , water ...
Air pollution caused by agriculture through land use changes and animal agriculture practices have an outsized impact on climate change. Addressing these concerns was a central part of the IPCC Special Report on Climate Change and Land [48] as well as in the 2024 UNEP Actions on Air Quality report. [49]
Climate change will accelerate the prevalence of pests and diseases and increase the occurrence of highly impactful events. [195] The impacts of climate change on agricultural production in Africa will have serious implications for food security and livelihoods. Between 2014 and 2018, Africa had the highest levels of food insecurity in the ...
Abiotic stress mostly affects plants used in agriculture. Some examples of adverse conditions (which may be caused by climate change) are high or low temperatures, drought, salinity, and toxins. [20] Rice (Oryza sativa) is a classic example. Rice is a staple food throughout the world, especially in China and India.
Dryland salinity is a natural process for soil, just like other processes such as wind erosion. Salinity degrades land by an increase in soil salt concentration in the environment, watercourse or soil in unirrigated landscapes, being in excess of normal soil salt concentrations in dryland regions.
Salinity in soil is caused by irrigating with salty water. Water then evaporates from the soil leaving the salt behind. Salt breaks down the soil structure, causing infertility and reduced growth. [citation needed] [14] The ions responsible for salination are: sodium (Na +), potassium (K +), calcium (Ca 2+), magnesium (Mg 2+) and chlorine (Cl −).
