The water problem on Dry Zone Sri lanka.
The water problem on Dry Zone Sri lanka. The drier regions have water shortages. Due to the spatially and seasonally unequal distribution of water in Sri Lanka. June, July and August, when rainfall is low. The evaporation is high, are the most troubled months in the Dry Zone. The occurring climate change has resulted in distorted weather patterns. The arrival 37 of estimated rainfall has not come when expected. Being a developing country, Sri Lanka has difficulties managing the agriculture as it is. The management of these aspects will therefore most likely have significant impact on the future.
The Sri Lankan Government is aware of this problem. It has formulated policies on how to manage the water situation in the future. The policies emphasize on the value of using the water efficiently. The task might, however, not be very easy to implement. For example, although a lot of money has been invested in the restoration of the irrigation schemes, it does not prevent people from taking water without permission, a problem that the interviewed farmers in Sooriyawewa were concerned about. However, Mahinda Rajapaksa who has been the president of Sri Lanka since 2005 was born in Hambantota and grew up in a family that cultivated paddy. It is widely recognized that the president has an interest in developing the area and the farmers put their hopes on that the region will experience more attention and development.
Weather patterns and climate change
it was not until the last extension project commenced in Uda Walawe Irrigation. Resettlement Project that the conservation of the ecosystem has considered. An exception in the rainfall trend has in Walawe basin where a small positive change of precipitation has been observed . Used models to project how the climate will change in the future. Walawe basin and what effect it will have on the food production. Results projected that the climate change in this region will increase the average food production. Due to the substantial carbon dioxide rise combined with the small precipitation and temperature increase. A weakness in the model is that the impact of the pathogens in the future was not accounted for.
The general climate trend in South Asia, including Sri Lanka, is an “increase in the occurrence of extreme weather. Events including heat wave and intense precipitation events”. IPCC further projects that the pathogen growth rate will increase as a consequence of the increase in temperature. Hence, the crops will become more vulnerable and the food production has affected. In the end this will, in particular, affect the poor people that rely on agriculture.
