Climate change is in the forecast however, detailed predictions about how crop production will be affected are less clear. Higher levels of CO2 may affect the growth rate and yield of crops, whereas higher temperatures or lack of precipitation may influence growing season length, crop type, or pests found in fields.

The U.S. Environmental Protection Agency is expected to publish crop modeling studies conducted in 18 countries. These studies, which Rosenzweig et al. (1993) list in Appendix 2 of Climate Change and World Food Supply, simulate the effects of climate change on crop yields, food production, and trade.

Crop impacts. On this page, we deal with these impacts of climate change on crop production: 1  Growing season. 2  Crop yield. 3  Water resources. 4  Insects, disease, weeds. 5  Soil quality.

In Climate Change and World Agriculture, Parry (1990) sketches a broad picture of the effects of climate change in the chapter Effects on Plants, Soil, Pests and Diseases..

• This involves: changes in land allocation and farming systems, breeding of crop varieties, new land management techniques, etc. This involves changes of land use that result from the farmer's response to the differential response of crops to climate change.

Climate Change Effects on Plant Growth and Yield Crop suitability and crop production : • Increases in crop yields are only expected in Northern Europe, while the largest reductions are expected around the Mediterranean and in the Southwest Balkans and in the South of European Russia.

Agriculture and climate change are inextricably linked—crop yield, biodiversity, and water use, as well as soil health are directly affected by a changing climate. Climate change, which is largely a result of burning fossil fuels, is already affecting the Earth’s temperature, precipitation, and hydrological cycles. Continued changes in the frequency and intensity of precipitation, heat waves, and other extreme events are likely, all which will impact agricultural production. Furthermore, compounded climate factors can decrease plant productivity, resulting in price increases for many important agricultural crops.

Facing with Unprecedented Conditions • Climate Change are recognized as a serious environmental issues. The build up of greenhouse gases in the atmosphere means that we can expect significant changes in the next few decades and probably for the whole 21th century. A decade ago, researchers asked the „what if” question.

UNFCC: Climate has been in a constant state of change throughout the earth’s 4.5 billion-year history, but most of these changes occur on astronomical or geological time scales, and are too slow to be observed on a human scale.

Climate scenarios have the ability to inform our choices about the likely impacts of temperature, precipitation, and seasonality on food production. They also allow us to guide agricultural sectors on the best methods to adapt to various climate consequences by evaluating impacts and identifying tradeoffs.
