How are deserts affected by climate change?
Climate change is reducing snowpacks and melting glaciers that provide freshwater to desert communities. … This desertification is exacerbated by human exploitation of ecosystems that border deserts, causing land degradation, soil erosion and sterility, and a loss of biodiversity.
What are the effects of drought on agriculture?
The effects of drought on crop production might be annual and perennial crop losses, damage to crop quality, income loss for farmers due to reduced crop yields, reduced productivity of cropland, insect infestation, plant disease, increased irrigation costs, cost of new or supplemental water resource development (wells, …
How does drought affect plants?
Without adequate water, biological processes, such as photosynthesis, are greatly reduced. Reduced photosynthesis means reduced plant growth, including root growth. … Besides the direct effects of drought, a plant under stress becomes more susceptible to insect and disease problems that can attack a weakened plant.
How are droughts affected by climate change?
Warmer temperatures lead to drying
Global warming increases the risk of drought in several ways. … As high air temperatures sap liquid water from soils and plant leaves, transforming it into atmospheric water vapor via a process called transpiration, ground-level drying will increase in some regions.
