Abstract/ Executive Summary:

Increasing water demand due to faced over population, overexploitation of natural resources and environmental degradation have notable tainted the world’s freshwater resources. Since the dawn of civilization, the means of water storage are explored and transferred by human to the area those suffer from a paucity of water. The ultimate goal of the agricultural development projects is to ensure a better living for the local people, but climatic issues are generated by this project in practice. The Teesta Barrage Project was also implemented to increase the agricultural production in the vast area of northern Bangladesh suffering from acute shortage of water every year. The aim of this study is to find out the change of climatic parameters due to construction of Teesta Barage Irrigation Project on its catchment area. After all, the project has succeeded in increased production of crops; improved lifestyle of rural people and conservation of community resources. Change in climate is noticed in surrounding project area, has some positive and negative impacts on the ecosystem.

Program Area: Risk Management in Agriculture

Non-commodity: Weather/Climate

Objectives:

To evaluate climatic changes in the catchment of Teesta basin due to construction of TBIP.

Methodology:

This study is based on analyses of secondary data sources. Secondary data have been collected from various agencies as: Bangladesh Water Development Board (BWDB); Teesta Barrage Monitoring Office, Dalia, Lalmonirhat; Water Supply Authority, Bangladesh; Ministry of Agriculture, Bangladesh and Bangladesh Bureau of Statistics (BBS). Global climate change may have serious impacts on water resources and agriculture in future. Variation in agro-climatic parameters during the year has led to the division of the year into crop seasons. Temperature in Bangladesh is suitable for cultivation and growth of crops throughout the year. Moreover, rainfall and flooding are the natural sources of soil moisture; these are supplemented by irrigation. Amount of evaporation, evapo-transpiration, humidity, wind load, wind pressure has a bit effect to crop production. Crop production is governed by moisture supply from rainfall and soil storage. Unreliable rainfall and droughty soils are the limitations to the crop production. The crop damage from drought is many times higher than the damage from flood. In this study, the changes of climatic parameters temperature, rainfall, humidity and evaporation due to construction of TBIP are discussed. The TBIP was constructed and implemented in 1990. There data sets of before and after 1990 are collected and analysed to assess the climatic impacts on the catchment area.

Achievement/Findings:

In recent years, the use of water for agricultural and industrial purposes has increased tremendously. It has recognized that water resources project like Teesta Barrage Project is necessary for the development of a nation. The successful implementation of the Teesta Barrage Irrigation Project was a dream comes true for them. The poverty stricken people could now hope for a better future. Based on the above discussion, the major findings of the study can be summarised as below:
(i) There is no significant change of temperature due to implementation of the project, whereas a significant change in rainfall pattern was observed.
(ii) There is a minor change in humidity but remarkable change is observed in evaporation.
(iii) Proper use of available surface water in Teesta Barrage catchment area is the best option, which would enable the farmers to use cheaper irrigation water that would also be environment-friendly.
