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]
A drought is a period of drier-than-normal conditions. [1]: 1157 A drought can last for days, months or years. Drought often has large impacts on the ecosystems and agriculture of affected regions, and causes harm to the local economy. [2][3] Annual dry seasons in the tropics significantly increase the chances of a drought developing, with ...
Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
Even though a drought is caused by a period of low rainfall, the nature, timing and effects on people, the environment, agriculture or businesses will vary. (PA Graphics)
The IPCC defines climate change adaptation in this way: "In human systems, as the process of adjustment to actual or expected climate and its effects in order to moderate harm or take advantage of beneficial opportunities." [9]: 5. "In natural systems, adaptation is the process of adjustment to actual climate and its effects; human intervention ...
Effects of climate change could have different impacts on groundwater storage: The expected more intense (but fewer) major rainfall events could lead to increased groundwater recharge in many environments. [64]: 104 But more intense drought periods could result in soil drying-out and compaction which would reduce infiltration to groundwater. [67]
A farm that can "produce perpetually", yet has negative effects on environmental quality elsewhere is not sustainable agriculture. An example of a case in which a global view may be warranted is the application of fertilizer or manure, which can improve the productivity of a farm but can pollute nearby rivers and coastal waters (eutrophication ...
The World Day to Combat Desertification and Drought is a United Nations observance celebrated each year on 17 June. [1] Its purpose is to raise awareness of the presence of desertification and drought, highlighting methods of preventing desertification and recovering from drought. Each year's global celebration has a unique, novel emphasis that ...
