Agriculture is a major contributor to greenhouse gas (GHG) emissions through crop cultivation, livestock, and land use change. These sources altogether account for about one-third of total anthropogenic GHG emissions, and four-fifths of them are located in developing countries [1, 2].Various mitigation strategies exist at different costs , but would require either change in consumption.

Incoming solar energy is called solar radiation Solar radiation warms the earth. Grain maize yield in the main arable areas of the European Community (E.C.) was calculated with a simulation model, WOFOST, using historical weather data and average soil characteristics.
The sensitivity of the model to individual weather variables was determined. Subsequent analyses were made using climate change scenarios with and without the direct effects of increased atmospheric CO2. The deleterious effect of the chemical fertilizers will itself start from the manufacturing of these chemicals, whose products and byproducts are some toxic chemicals or gases like NH4, CO2.
This natural control, known as the greenhouse effect, and its feedback on the climate has been explored by many theoretical and model studies suggesting that increased concentrations of greenhouse gases result in increased radiative forcing and hence increasing temperatures at the surface [Callendar, ; Houghton et al., ].
Ecology: Principles and Applications is a comprehensive textbook for A-level students and first-year undergraduates taking courses in biology, geography and Earth sciences, who require an introduction to ecology. Studies of human ecology are integrated into the text, and the links to related disciplines are emphasised.
The text begins with the ecology of individual organisms and moves on 4/5(5). The experience of greenhouse production, which emerged in northern Europe, stimulated development in other areas, including the Mediterranean, North America, Oceania, Asia and Africa, with various rates and degrees of success.
It has been shown that a mere transposition of north European solutions to other parts of the world is not a valid process. The greenhouse effect is a natural process that warms the Earth’s surface.
When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs). Human expansion throughout the world caused that agriculture is a dominant form of land management globally.
Human influence on the land is accelerating because of rapid population growth and increasing food requirements.

To stress the interactions between society and the environment, the driving forces (D), pressures (P), states (S), impacts (I), and response (R) (DPSIR) framework.
Greenhouse gases let the sun’s light shine onto the Earth’s surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse.
The greenhouse effect keeps Earth’s climate comfortable. Without it, surface temperatures would be cooler by about 33 degrees Celsius. A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.
These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. Greenhouse effect, a warming of Earth’s surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapor, carbon dioxide, methane, and certain other gases in the air.
Of those gases, known as greenhouse gases, water vapor has the largest effect. World Health Organization Regional Ofﬁce for Europe, European Centre for Environment and Health, Rome, Italy human-enhanced greenhouse effect CONTENTS v.

Crop and livestock production is projected to decrease and may even have to be abandoned in parts of Europe’s southern and Mediterranean regions due to the increased negative impacts of climate change, according to a European Environment Agency (EEA) report published today.
The study says that adapting to climate change must be made a top priority for the European Union’s. Since each greenhouse gas (GHG) has its own radiative capacity, all three gasses (CO 2, CH 4 and N 2 O) must be accounted for by calculating the net global warming potential (GWP) in a crop production system.
To compare the impact of GHG fluxes from the rice growing and the fallow season on the annual gas fluxes, and their contribution to the. The main greenhouse gases that occur in nature are carbon dioxide, methane, and nitrous oxide. Without the greenhouse effect, the planet would be too cold to support life.
Over time, the amount of greenhouse gases trapped in Earth's atmosphere has increased significantly, causing worldwide temperatures to rise. Electricity Sector Emissions. Total Emissions in = 6, Million Metric Tons of CO 2 tages may not add up to % due to independent rounding.
* Land Use, Land-Use Change, and Forestry in the United States is a net sink and offsets approximately 12 percent of these greenhouse gas emissions, this emissions offset is not included in total above.
Collectively, all of these gases lead to what is called the enlarged greenhouse effect because all of them absorb infrared radiation (Houghton et al., ). It is estimated that about 50% of CO 2 emitted to the atmosphere remains in it and the other 50% is taken up by the ocean and terrestrial ecosystems.
A greenhouse can, in fact, become a mini-ecosystem if the adept gardener can manage the interaction between abiotic factors (such as wind, snow, oxygen, carbon dioxide) and the biological community.
Hence, in agro-ecosystems the remaining soil fauna, microorganisms, and any surviving weeds provide the only species diversity. For example in the U.K a wheat crop will only support the insects or animals (i.e.
field mouse) that feed on wheat, and any species that can then feed on these primary consumers. Climate change - Climate change - Greenhouse gases: Greenhouse gases are gas molecules that have the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the phenomenon known as the greenhouse effect.
Carbon dioxide, methane, and water vapour are the most important greenhouse gases, and they.Greenhouse gases. Life on Earth depends on the presence of greenhouse gases in the atmosphere to insulate our planet’s surface against the chill of space; without them the Earth’s average climate would be about 33 °C cooler.
The atmosphere is largely transparent to the. It is very old wisdom that climate dictates farm management strategies.
In recent years, however, we are increasingly confronted with claims that agriculture, livestock husbandry, and even food consumption habits are forcing the climate to change. We subjected this worrisome concern expressed by public institutions, the media, policy makers, and even scientists to a rigorous review, cross.
