Abstract/ Executive Summary:

Climate change the recent most menace issues especially for the low lying deltaic country like Bangladesh and have a variety of precarious effect on the livelihood pattern of the selected community. The study shows that due to the consequence of climatic disruption the people in the selected region have faced external cost in economic consideration which affects their income level per year. People’s perception on climate change vulnerabilities for the study area revealed that cyclone and tidal surges are causing most of their external cost. In case of cyclone about 95% of the community people are in food shortage, about 83% are homeless and about 82% of respondent facing the problem of property loss. On the other about 97% of respondent have the vulnerability in their land productivity and facing drinking water crisis from the effect of salinity problem. Most remarkable changes of occupational level in the selected community are in fisheries production and agricultural activities. This significant change is occurred due to the rapid expansion of gher farming in this area and causing behind it for increasing rate of salinity intrusion in their agricultural land and decreasing the production rate. Business sector and livestock’s production is another victim of external cost induced vulnerability from the impact of climate change. Due to the effect of externality the income level of the selected people has been decrease per year. On the based of occupational pattern income level of all sectoral people has been decreasing up to a significant level from their total on year basis.

Keywords: Climate Change, Perception, External cost, Income level, Salinity intrusion and vulnerability

Location: Chila union, Mongla upazila, Bagerhat district

Start Date: 00-00-2011

End Date: 00-12-2011

Program Area: Risk Management in Agriculture

Non-commodity: Adoption and mitigation technology

Objectives:

1. To study the consequence of climatic disruption the people in the selected region have faced external cost in economic consideration which affects their income level per year.

Methodology:

The study area is located at the south west part of Bangladesh and it has been selected on the basis of the criteria as such climate induced natural disasters. In order to select the sampling site, a reconnaissance survey has been conducted in the study area. Selection of the Study Area and Sampling villages: Chila Union of Mongla Upazila consist 14 Village. Among these villages, 4 villages were selected randomly for data collection which representing 25% of the study area. As the population of the study area is uniform, thus 25% population can represent the total population in the study area. Sample Size Determination: The size of the sample was determined using standar equation. Data Collection Procedure: Both primary and secondary data has been collected for the study. The primary data is collected through personal interview by using simple random sampling method. The overall household survey has been completed into four intervals. The secondary data is collected from various government and non-government organization and from the Internet then efforts have been made to process the data. Before represent the data in a systematic way some feedbacks have been gathered from the experienced person and finally the study report is prepared.

Achievement/Findings:

The study findings proved that the community is disaster prone and is affected almost every year by natural hazards of some kind like salinity intrusion, floods, torrential rains, erosion, and cyclones. But the extent of environmental risk for the selected community is not fully determined, and the benefits of corrective initiatives from the Govt., NGOs and CBOs are not clearly distinguished. Until more is known about their climatic risks, and hence the opportunity costs of major initiatives simply cannot be justified on economic grounds. Despite the inherent difficulties, there has to progress in recognizing the relevant issues of direct and indirect problems relating to the impact of climate change, acknowledging the unknowns and investigating alternative solutions. Now it has been established that if climate change strategies are to be strengthening and implementing into the identified grounds in a right way then it’s obvious to reduce the external cost facing by the society. Thus, the policy or strategy of climate change needs more prominence consideration to the policy makers for strengthening the existing ones and updating timely with changing dimension of cause and effect.
