Global warming affects agriculture in a number of ways, including through changes in average temperatures, rainfall, and climate extremes (e.g., heat waves); changes in pests and diseases; changes in atmospheric carbon dioxide and ground-level ozone concentrations; changes in the nutritional quality of some foods; and ...

Global warming could lead to an increase in pest insect populations, harming yields of staple crops like wheat, soybeans, and corn. While warmer temperatures create longer growing seasons, and faster growth rates for plants, it also increases the metabolic rate and number of breeding cycles of insect populations.

Climate change could affect our society through impacts on a number of different social, cultural, and natural resources. For example, climate change could affect human health, infrastructure, and transportation systems, as well as energy, food, and water supplies.

Nutrition-health: Increased water scarcity due to climate change reduces the capacity to produce food and its quality, which has serious implications for food security, nutrition and health. In Ethiopia alone 9.7 million people are currently in need of emergency food aid.

Climate change and poverty. Climate change and poverty are interrelated events. While global warming affects the natural environment, especially agriculture, it also affects humans. Climate change globally increases cycles of poverty, particularly in low-income communities.

New research shows that increases in rainfall and extreme weather because of climate change will increase the amount of nitrogen polluting rivers and other waterways. The findings underscore the urgency of reforming agriculture to dramatically reduce the use of nitrogen fertilizers.

Climate change affects the social and environmental determinants of health – clean air, safe drinking water, sufficient food and secure shelter. Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress.

Climate change will also have many non-thermal impacts on fish populations. For example, changes in the strength, direction and location of ocean currents can affect the probability that fish eggs and larvae survive and grow. Moreover, as temperatures rise, the ability of the ocean to retain oxygen will decrease.

Agriculture contributes to climate change At every stage, food provisioning releases greenhouse gases into the atmosphere. Farming in particular releases significant amounts of methane and nitrous oxide, two powerful greenhouse gases.

Climate change could threaten these resources, as well as the goods and services they produce and the jobs and livelihoods of those who depend upon them. For example, climate change will likely affect farming communities, tourism and recreation, and the insurance industry.

Warmer temperatures, sea level rise and extreme weather will damage property and critical infrastructure, impact human health and productivity, and negatively affect sectors such as agriculture, forestry, fisheries and tourism.

Climate change could alter ocean food chains, leading to far fewer fish in the sea. Climate change is rapidly warming the Earth and altering ecosystems on land and at sea that produce our food. ... But as this happens, it will change ocean circulation patterns and make ocean food chains less productive.

Key points in this POSTnote include: Climate change drives changes in marine ecosystems that affect fisheries' productivity and food security. ... These changes are altering the distribution, abundance and health of commercial fish species, and the marine ecosystems on which they depend.

Global warming affects evapotranspiration—the movement of water into the atmosphere from land and water surfaces and plants due to evaporation and transpiration— which is expected to lead to: Increased drought in dry areas.

A warmer climate will have a major impact on the Arctic and result in major changes for plant and animal species. Melting permafrost will cause large quantities of methane and carbon dioxide to be released, boosting global temperatures already on the rise.

Climate change is affecting agricultural production in the Northeast. Heavy precipitation events can damage crops and wetter springs may delay planting, resulting in later harvest and reduced yields. Longer, drier summers may reduce water availability and increase plant heat stress, also reducing yields.

Climate change has both direct and indirect effects on agricultural productivity including changing rainfall patterns, drought, flooding, and the geographical redistribution of pests and diseases. Conflict can arise when natural resources are not equitably managed.
