Climate Change&Its Implications For Small Farmers
In the earth’s history, climate change is a natural, slow moving phenomenon. But its unpredictability and the rapidity with which it is happening now have made it a problem. Today, the threat of climate change is becoming a major problem to the lives in the earth. The threat of climate change on global survival systems has emerged as a critical, urgent issue. The earth’s average temperature has increased, some weather phenomena have become more frequent and intense (for example, heat waves and heavy downpours of rains), while others have become less frequent and intense (for example, extreme cold events). A warmer earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife and humans. An ecosystem consists of the biological community that occurs in some locale and the physical and chemical factors that make up its non-living (abiotic) environment. Rain forests and tundra, coral reefs and ponds, grasslands and deserts are examples of ecosystems. Climate differences from place to place largely determine the types of these ecosystems. Broad climate stability is critical to existing ecosystems adapted to a particular climate. A colder climate may wipe out species in a particular ecosystem adapted to a hot climate and vice versa. All of this is going to have its most adverse effect on the vulnerable sections of society in developing countries, like small food producers who primarily depend on farming and fishing (and gathering) for their livelihood and survival. In fact, the impact of climate change on the human production systems is already evident and ominous - with increasing unpredictability of local weather conditions upsetting agricultural production patterns. Warmer weather or climate advances sowing and harvesting periods, affects yields, reduces water availability, increases incidences of pest attacks and exacerbates drought.
