how are increasing temperatures likely to affect agriculture

The rise in temperature leads to an increase in the amount of water loss through Evaporation and transpiration. Therefore, greater quantities of water are needed for agricultural production, and higher temperatures lead to an increase in fungal and viral diseases and insect infestation.

Answer

How does heat stress affect the agricultural sector?

 · Answer:Climate change can disrupt food availability, reduce access to food, and affect food quality. For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity.

What are the factors that affect agricultural productivity?

 · 15. How are increasing temperatures likely to affect agriculture? A. Cz and C4 plants will be affected differently. B. Less water will be needed to irrigate. C. Insects will be able to thrive farther away from the equator. D. Nitrogen will be more available to plants.

What is the effect of temperature changes on plants?

 · Changes in ozone, greenhouse gases and climate change affect agricultural producers greatly because agriculture and fisheries depend on specific climate conditions. Temperature changes can cause habitat ranges and crop planting dates to shift and droughts and floods due to climate change may hinder farming practices.

Why do farmers change crops?

 · Climate change is affecting crop and livestock yields worldwide, which will lead to changes in food and fiber consumption, prices of agricultural commodities, and farm incomes. The extents of the effects are still unknown. For more information go to: Agriculture and Climate Change and Climate Solutions. Related Articles

How does climate affect food?

Any climate-related disturbance to food distribution and transport, internationally or domestically, may have significant impacts not only on safety and quality but also on food access. For example, the food transportation system in the United States frequently moves large volumes of grain by water. In the case of an extreme weather event affecting a waterway, there are few, if any, alternate pathways for transport. High temperatures and a shortage of rain in the summer of 2012 led to one of the most severe summer droughts the nation has seen and posed serious impacts to the Mississippi River watershed, a major transcontinental shipping route for Midwestern agriculture. This drought resulted in significant food and economic losses due to reductions in barge traffic, the volume of goods carried, and the number of Americans employed by the tugboat industry. The 2012 drought was immediately followed by flooding throughout the Mississippi in the spring of 2013, which also resulted in disruptions of barge traffic and food transport. [3] Transportation changes such as these reduce the ability of farmers to export their grains to international markets, and can affect global food prices.

How does heat affect livestock?

Drought may threaten pasture and feed supplies. Drought reduces the amount of quality forage available to grazing livestock.

How does temperature affect salmon?

Many steps within an aquatic animal’s lifecycle are controlled by temperature and the changing of the seasons. For example, in the Northwest warmer water temperatures may affect the lifecycle of salmon and increase the likelihood of disease. Combined with other climate impacts, these effects are projected to lead to large declines in salmon populations. [1], [11], [12]

What are the potential changes in veterinary practices?

Potential changes in veterinary practices, including an increase in the use of parasiticides and other animal health treatments, are likely to be adopted to maintain livestock health in response to climate-induced changes in pests, parasites, and microbes.

Why is drought a challenge?

Dealing with drought could become a challenge in areas where rising summer temperatures cause soils to become drier. Although increased irrigation might be possible in some places, in other places water supplies may also be reduced, leaving less water available for irrigation when more is needed.

How does drought affect pasture?

[1] More extreme temperature and precipitation can prevent crops from growing. Extreme events, especially floods and droughts, can harm crops and reduce yields.

What are the challenges of droughts?

Changes in the frequency and severity of droughts and floods could pose challenges for farmers and ranchers and threaten food safety. [3] . Meanwhile, warmer water temperatures are likely to cause the habitat ranges of many fish and shellfish species to shift, which could disrupt ecosystems. Overall, climate change could make it more difficult …

How cold does it need to be for trees to grow?

Many tree crops require cold for a certain number of hours below a critical temperature, commonly 45 degrees Fahrenheit, to stimulate the growth of leaves and flowers.

What did Lee emphasize about market conditions?

Lee emphasized that market conditions exert a great deal of influence on the crops growers choose to plant. Growers who consider trends in climate change may choose different cultivars rather than different crops, such as a walnut variety that requires fewer chilling hours.

What crops were grown in Yolo County?

The crops included processing tomatoes, rice, alfalfa, wheat, corn, prunes, grapes, walnuts, almonds, safflower, pasture and other fruit.

Why is it important to increase the growing season length?

An increase in growing season length may sound like a great thing for food production, but as we’ll see, that can make plants more vulnerable to late frosts and can also allow for more generations of pests per growing season, thus increasing pest pressure.

Will the NCCV increase temperatures?

ANSWER: The NCCV shows that temperatures are predicted to increase, including max and min temperatures. Growing seasons will be longer. Increased temperatures could result in heat stress for some crops and increased yields for others.
