Climate Change Impacts and Adaptation for Coastal Areas Issues and Options

摘要

Agriculture - which feeds the entire human population - is under great threat due to climate change. The climatic changes are resulting in erratic weather patterns and the impacts are already being manifested in many parts of the world, particularly in tropical regions. Of late many agricultural systems are nearing crisis point. More and more chemical fertilizers are now needed to produce per kg of food grain. Since the last few decades the average surface temperatures of the earth have risen appreciably. Water is becoming scarce in many regions. These phenomena have serious implications on bio-diversity as well as economics and livelihood patterns of the people. This is particularly true in developing countries where a large portion of their population depends directly on agriculture for their livelihoods and their economies are closely linked to agriculture.
