climate threats on agriculture

1. T HREATS TO AGRICULTURE REHAN ASGHAR 22011514-114

2. Impacts on Crops Higher CO 2  levels can affect crop yields . Some laboratory experiments suggest that elevated CO 2  levels can increase plant growth.  However, other factors, such as changing temperatures, ozone, and water and nutrient constraints, may counteract these potential increases in yield Air pollution may also damage crops, plants, and forests .   For example, when plants absorb large amounts of ground-level ozone, they experience reduced photosynthesis, slower growth, and higher sensitivity to diseases

3. Impacts to Soil and Water Resources Climate change is expected to increase the frequency of   heavy precipitation  in the United States, which can harm crops by eroding soil and depleting soil nutrients Heavy rains can also increase agricultural  runoff into oceans, lakes, and streams.   This runoff can harm water quality .  When coupled with warming water temperatures brought on by climate change, runoff can lead to depleted oxygen levels in water bodies. This is known as  hypoxia

4. Agriculture and the Economy Pakistan has a mixed economy with agriculture, industry, and services sectors contributing to the GDP Agriculture : Contributes around 19-20% to the GDP and employs a large portion of the workforce. Cattle, corn, dairy products, and soybeans are the top income-producing commodities if we spend much on agriculture its produce more jobs on food security jobs and farms jobs

5. What We Can Do Incorporate climate-smart farming methods. Farmers can use climate forecasting tools, plant cover crops, and take other steps to help manage climate-related production threats.  Boost crop resistance. Adopt research-proven ways to reduce the impacts of climate change on crops and livestock such as reducing pesticide use and improving pollination . Join AGSTAR . Livestock producers can get help in recovering methane, a potent greenhouse gas, from biogas created when manure decomposes .
