Impact of Global Warming on Bangladesh Agriculture and Role of Agricultural Engineers

Murshed Alam
Associate Professor
Department of Farm Power & Machinery, Bangladesh Agricultural University, Mymensingh- 2202, Bangladesh.

Abstract/ Executive Summary:

Global is warming due to damping of green house gases (GHG) in the atmosphere. This is changing climate around the world. In Bangladesh, the average annual increase of temperature would be 1.6°C and 3.2°C by 2030 and 2075 respectively. The precipitation would be increased in the monsoon and it would be decreased in winter. The evaporation would be 6% higher in 2075 compare to that in 1990. The sea level would be rise 0.7 m by 2075. As a result, such as agricultural sectors of Bangladesh would be affected. The role of agricultural engineers was discussed to face the problem of global warming in Bangladesh.

Program Area: Risk Management in Agriculture

Non-commodity: Emission and measurement of green-house gas

Objectives:

To discuss the impact of global warming on Bangladesh agriculture sectors and role of agricultural engineers to face the problem of global warming.

Methodology:

The impact of global warming on Bangladesh was assessed on the basis of changes in temperature, evaporation, precipitation, sea level rises in Bangladesh. The affect of climate changes on present elevation, inundation land type and cultivated crops of Bangladesh were appraised. The information were collected from different sources such as BBS, BNL and personal contact. The quantitative analysis of the impact of global warming in Bangladesh was not possible due to lack of proper data but qualitative assessments were done.

Achievement/Findings:

The government of Bangladesh, specially, should take immediate action to increase the forest area and motivate to people to grow more trees in the country. Since, a mature tree can reduce surrounding temperature by discharging moisture and it can reduce air velocity of strong wind. Beside this, the government must complete the proposed embankment project along the major rivers. It is hope that Bangladesh has plan to completed works of all embankments along the major rivers by 2075. She is working to built the Ganges Bramaputra barrage which would supply normal water to the southwest region of the country for reducing salinity. The government has also taken several programs to grow more trees in the country. All of these would help to mitigate the problem causes by global warming in Bangladesh.
