There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security.Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought, heat waves and flooding. [5]
The global population is still increasing and will eventually stabilize, as some critics doubt that food production, due to lower yields from global warming, can support the global population. Agriculture can have negative effects on biodiversity as well. [5]
The vulnerability of agriculture to climatic change is strongly dependent on the responses taken by humans to moderate the effects of climate change. [ 6 ] Changes in crop and livestock viability are forcing the farmers to find better choices of crops and animals, capable of adaption to temperature changes and water availability.
Similarly, an older study found that if 1.1 °C (2.0 °F) of warming occurs between 2005 and 2045 (rate comparable to hitting 2 °C (3.6 °F) by 2050), then under the current livestock management paradigm, global agricultural costs would increase by 3% (an estimated $145 billion), with the impact concentrated in pure pasturalist systems.
Despite this, all agricultural practices have been found to have a variety of effects on the environment to some extent. Animal agriculture, in particular meat production, can cause pollution, greenhouse gas emissions, biodiversity loss, disease, and significant consumption of land, food, and water.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Human activity since industrialization has led to a huge increase in the production of carbon dioxide, a greenhouse gas that contributes to rising global temperatures. Scientists warn that if carbon dioxide and other greenhouse gas emissions continue to rise at their current rates, Earth’s temperatures could increase dramatically in future ...
With 21% of global methane emissions, cattle are a major driver of global warming. [ 84 ] : 6 When rainforests are cut and the land is converted for grazing, the impact is even higher. In Brazil, producing 1 kg of beef can result in the emission of up to 335 kg CO 2 -eq. [ 85 ] Other livestock, manure management and rice cultivation also emit ...
