What are some possible effects of global warming on agriculture and forestry?
It is difficult to predict the future, but in 2001 the IPPC issued a Report: Climate Change 2001: Working Group II: Impacts, Adaptation and Vulnerability (See the link below).
Here are some of the suggested impacts on agriculture and forestry:
- Climate change will affect crop yields and irrigation demands.
- Climate change will affect the composition and geographic areas of forests as well as product health and productivity.
- Water Resources will be affected: water supply, quality and competition for water.
- The following quote illustrates how much we rely on our ecosystems for goods and services: "Forests and woodlands provide many goods and services that society values, including food, marketable timber and non-wood products (fuel, fiber, construction material), medicines, biodiversity, regulation of biogeochemical cycles, soil and water conservation (e.g., erosion prevention), carbon reservoirs, recreation, research opportunities, and spiritual and cultural values." The report goes on to say that changes in climate are likely to affect all of these, especially the socio-economic systems.
- Moderately warmer weather and increased CO2 in the atmosphere may help some crop growth (up 30% in the case of rice, soy and wheat), but with increased temperatures the grain yield drops 10% for every 1˚C rise above 26˚C.
- Agricultural areas may suffer erosion from increased wind and water from short term changes in weather.
- The growth of agricultural pests (weeds, insects and pathogens) under climate change is being studied with varying results. For example, higher temperatures increase the severity of rice leaf blast epidemics in cool subtropical zones, but in warm humid subtropics higher temperatures lower the severity of the epidemics.
- Farm animals are affected by warmer temperatures, influencing their performances in growth, milk and wool production, reproduction, health and well-being.
- Increased temperatures may lead to increased demand for water from agriculture and wildlife, including farm livestock. It may also lead to reduced water availability.
- Adaption costs for agriculture, including retraining farmers for new practices, as well as the provision of new irrigation may be considerable.
- The cost of basic food will rise, especially with temperature rises of more than 2.5˚C, as agriculture will not be able to absorb increased costs.
- "Africa is projected to experience marked reductions in yield, decreases in production, and increases in the risk of hunger as a result of climate change."
- Cold winters will no longer kill the eggs of the boreal forest insect pests.
- Studies in Britain suggest that 10% of all Nature reserves could be lost in a few decades.
- The effect of increased concentrations of CO2 on decomposition, plant productivity, and carbon storage could be just as damaging as the effects from climate change.
some possible effects of global warming is sea levels could rise.Also the weather will start to change.
The possible effects from global warming have caused great concern. It is possible that I could be a millionaire one day.
There really aren't any limitations of global warming. Literally anything is possible if something is not done to slow down the effects of global warming.
The disappearance of both global Glaciers and Ice Sheets and the Rapid spread of Deserts.
They want to scare you, global warming is false. do your own research and you will find that this is true. we had the coldest winter in extended memory all across the U.S.
All nations that burn fossil fuel have bad effects on global warming.
effects of gloal warming in India
The effects of the global warming include: The rise of seas, due to the melting of ice, And a rising climate
It means increasing the size of carbon pools and carbon sinks, like tropical forests, so that more carbon can be extracted from the atmosphere. It is part of a mitigation strategy in biological conservation concerned with forestry to tackle global warming and its effects on climate change.
Melting glaciers and land ice raising sea levels and permanently flooding many of the world's great cities as well as destroying vast quantities of coastal land presently used for food crops. Heat waves, wild fires, famines, and storm tides causing havoc, and millions of global warming refugees moving into countries further from the equator desperately seeking food and shelter.
global warming could affect everything
Reduction in secondary pollutants is not a possible consequence of global warming.
Effects: - Global warming - Health effects - Destruction of planktons
Agriculture contributes to global warming by the release of methane from decaying plant materials left in the fields and from the flatulence of the animals raised for meat, leather, wool, etc. On the flip side, agriculture removes CO2 from the air as the plants absorb it and release O2 back to the atmosphere.
Global warming is the recent increase in the temperature of the earth and its atmosphere. The possible effects of this global warming are various kinds of climate change, including more frequent and more severe weather 'events' (storms, floods, droughts, heat waves, etc). Other results include melting of sea ice, ice caps and glaciers, leading to rises in sea levels and alteration to animal habitat that may lead to extinction.
There are many effects. Global warming is a example.
Global warming can be halted by halting the greenhouse gases. These gases are the ones responsible for warming.
The greenhouse effect keeps the earth warm enough for life. It is the enhanced (or accelerated) greenhouse effect which is causing global warming. Global warming is causing climate change which will mean rising temperatures and sea levels, changes in rainfall patterns disrupting agriculture, drought and famines in Africa, and many other serious effects.
Neither is particularly useful.
There are several thesis statements one could make about global warming and its effects in the world. For example: Global warming is resulting in more frequent and more severe weather events.
Everybody is affected by global warming. This phenomenon can the water supply, agriculture, the natural environment, and power and transportation systems.
polar ice caps melting habitats being destroyed as some animals can only survive in certain temperatures drought hope this helps :)
No, the sun is not affected by global warming. Global warming is happening on the earth and its effects are confined to our world
The positive effects are personal properties. The negative effects are pollution and global warming.
Global warming and other devastating effects on the environment
Global warming is heating of earth. It causes ozone depletion.
Global warming is the warming of globe. Ozone layer is the layer of ozone. It is depleting due to former.
species die, beaches get polluted, and it effects global warming.
It is possible, but that is difficult to say, as there is no single consensus on the magnitude of the impact of global warming.
Global warming and climate change.
Ocean Warming is caused by Global Warming. Some effects of Ocean Warming are... Coral reefs dying, that means that a lot of fish are going to die as well Ice melting, I know that is caused by the sun but Ocean warming contributes to it. And when the ice melts, our shoreline will come closer and when that will happen, we have to move more inland and if we do that we will eventually not… Read More
Which region would Global warming likely have the greatest negative effects on the economy of Canada?
For global warming to have the greatest negative effects on the economy of Canada it would have to affect Saskatchewan and Nova Scotia.
Climate change and global warming will have very negative effects on Pakistan. Crops will be damaged by the high temperatures, and potential flooding could occur on the flat lands.
Threats of the temperate grasslands are global warming and the conversion of agriculture.
Yes, they are two atmospheric effects. No, they are not related.
There are a number of ways detergent can be used to cause Global Warming. Detergents can be burned for example.
Livestock agriculture is more vulnerable to disasters now than in past generations because of global warming. Due to global warming, some disasters like floods or famine occur in higher frequency than they used to.
There are various possible consequences of global warming. For example, the ice caps will melt and many parts of the world will be underwater.
Does the US provide protection against adverse consequences for human populations during global warming?
No. As far as we know the US has no plans to protect its population against the effects of global warming. Building sea walls around all its low-lying cities is probably not possible. Perhaps the US is working on serious plans for how to stop global warming, but we've heard little so far.
it effects everywhere
overexploitation of resources and global warming.
The polar areas
The most obvious impact is warming of the troposphere, due to the enhanced greenhouse effect. As a result of this warming, the ocean is less able to take more carbon dioxide. This results in a larger percentage of carbon dioxide remaining in the atmosphere, further enhancing the greenhouse effect.
