Climate Change Affects
Climate change affects agriculture in many ways, both positively and negatively. Some of the effects are:- Changes in agricultural productivity: Climate change can make conditions better or worse for growing crops in different regions. For example, higher temperatures and carbon dioxide levels may increase some crop yields, but also reduce the nutritional quality of major cereals. On the other hand, droughts, floods, heat waves, and pests can damage crops and lower yields¹². - Changes in water availability: Climate change can alter the amount and timing of rainfall, snowmelt, and runoff, which affect the availability and quality of water for irrigation and other agricultural uses. Water scarcity can reduce crop production and increase the risk of conflicts over water resources¹³. - Changes in soil quality: Climate change can affect the physical, chemical, and biological properties of soil, which are essential for plant growth and soil fertility. For example, heavy rainfall can cause soil erosion, which reduces the amount of organic matter and nutrients in the soil. Higher temperatures can also increase soil evaporation and salinization, which affect soil moisture and salinity¹⁴. - Changes in pest and disease pressure: Climate change can alter the distribution and abundance of pests and diseases that affect crops and livestock. For example, warmer temperatures can expand the range and activity of insects, fungi, bacteria, and viruses that can harm plants and animals. Some pests and diseases may also become more resistant to pesticides and drugs due to climate change¹⁵. - Changes in food security and livelihoods: Climate change can affect the availability, accessibility, utilization, and stability of food for millions of people who depend on agriculture for their food and income. Climate change can reduce crop yields, increase food prices, disrupt food supply chains, and increase the risk of hunger and malnutrition. Climate change can also affect the livelihoods of farmers, fishers, herders, and other agricultural workers by reducing their income, assets, and opportunities¹ .
