![]() ![]() Agroforestry is a sustainable land-use system and practice where woody perennials(trees,shrubs) are deliberately planted on the same land unit with agricultural crops & or animals either in spatial arrangement or temporal sequence. It combines agriculture (both crops & animal production) with forestry on the same piece of land either simultaneously or sequentially. Agroforestry system consists of bush fallow and shifting cultivation, Taungya, Shade trees, fodder trees, shelter belts and hedge rows and alley cropping. A long term change in the earth's climate or of a region of earth. Global warming leads to climate change .Global warming refers to increase in Earth?s average surface temperature due to rising levels of greenhouse gases (the gases which traps heat ,make up less then 1% atmosphere eg.C02,CH etc). Some gases act like blanket trapping heat ,these gases are called ?greenhouse gases .This effect known as Natural Greenhouse Effect. Human activities increased the emission of greenhouse gases in the Earth surface called ?Enhanced Greenhouse Effect and this is the causing the Earth to heat up,or global warming. These greenhouse gases trap the solar radiation and can cause the Earth average temperature increase. Major greenhouse Gases are Carbon dioxide, Methane, Nitrous oxide, Ozone, etc. Developing countries are most vulnerable to burnt the climate change.the global concentrations are not effective to stop the increasing atmospherics GHG?s and these are the primary drivers of the climate change.The local climate and the terrestrial ecosystem will change,threatening the biotic and human livelihoods. The developing countries are faced with the urgent needs for the development,to improve the food security, reduce the poverty, provide an adequate standard of living for growing population. Agroforestry systems are more important opportunities provides for the creating the synergies between action undertaken for creating the connections action taken for the mitigation and activities undertaken for the adaptation.Climatic variability is well buffered by the agroforestry because of the permanent tree cover and varied ecological niches. Resilience or covering after or disturbance(eg:extreme weather events,or market failure)in well performed by the diversified temporal and spatial management options. |
