Land and Water are the two major constraints in development of agriculture. Therefore it is mandatory to conserve them through all available technologies .

Land:

Even though soil is one of the most important resources there is not actually that much available for making food, fiber, and shelter. Earth has 58 million square miles of land surface, out of which only there are 0.2 hectares of land per person (0.5 acres). As the population of the world grow rapidly more pressure is put onto the same areas of land to create more food. When the natural ecosystems such as wetlands, forests, woodlands, grasslands, steppes, savannas etc., are opened to farming, the soil organic matter content reduces by 40 per cent converting to carbon dioxide, methane, nitrous oxide, hydrochloroflurocarbons in the lower atmosphere. They are collectively called as greenhouses gases responsible for heating of the surface of the planet. This loss of carbon from the soil can be counteracted by carbon input. These strategies put into practice constitutes “Carbon Farming”.

Carbon Credits are certificates that represents quantity of greenhouse gases that have been kept out of air or removed from it. One carbon credit certifies that one metric ton of carbon di oxide has been removed from the atmosphere. It is estimated market prices of credits could rise significantly.
