Abstract/ Executive Summary:

Pangasius catfish, Pangasianodoan hypophthalmus farming has been evolved to a shape of commercial enterprise over the last two decades in north-central part of Bangladesh, particularly in Mymensingh area but there is a lack of quantitative and qualitative data on the impacts of it on land use pattern. This study was conducted using multiple methodological tools including participatory rural appraisal (PRA) tools and mainly questionnaire based farm survey to assess the impacts of Pangasius farming on land use from February to September, 2009. The mean farm size (ha), water area (ha) and dyke area (ha) was 1.36±1.25, 1.06±1.31 and 0.30±0.27, respectively. The Pangasius productivity was significantly and positively correlated with water area and dyke area. Around 10.1% area of the study area was converted to Pangasius farm which was previously used as rice-field. Farmers expanded their farm area by taking leased lands which contributed to 56.47% of total farm area and the lease value of Pangasius pond was doubled compared to agriculture land. Around 48% area of dyke were used to produce agriculture crops and the production was 71.01% lower but profit margin was 76.58% higher than normal land. The discharging wastewater of Pangasius pond also increased rice productivity in adjacent agriculture farm by 10% and additionally reduced fertilizer and irrigation cost by 30% and 40%, respectively.

Keywords: Pangasius aquaculture, Impact on land use pattern, Bangladesh

Location: Dhanikhola, Trishal upazila, Mymensingh.

Start Date: 00-02-2009

End Date: 00-09-2009

Program Area: Animal Health and Management

Commodity: Land development productivity

Objectives:

1. To assess the impacts of Pangasius aquaculture on land use patterns in selected areas in Bangladesh.

Methodology:

This study was conducted in Dhanikhola of Trishal upazila under Mymensingh district from February to September, 2009. Pangasius farming first started by private enterprise in Trishal which was very close of the study village. The authors also reported that the number of Pangasius farms higher in Dhanikhola compared to other areas of Trishal upazila. This village was a typical Pangasius producing area in terms of early development, having large number of farms, higher production level and better access to the markets. There were 135 farms in the study area and out of which, 60 farms were randomly sampled for this study. The information of this study was collected based on questionnaire interview and in addition, key informant interview and focus group discussion. Draft questionnaire were tested with few farmers before preparing final questionnaire. During the testing period, attention was given to include any new information and based on the feedback the final questionnaire was prepared. The collected information were entered into the data-base software MS-Excel and analyzed by SPSS (version 11.5). The findings were presented in textual, tabular and graphical forms to explicit impacts of Pangasius aquaculture on land use pattern.

Achievement/Findings:

Mainly middle aged and educated people were involved in Pangasius aquaculture, predicting further entrepreneurial growth of Pangasius farming in Mymensingh region of Bangladesh. Pangasius farming added lease value to upland rice fields as well as increased rice productivity of the surrounding upland rice-field. The dyke of Pangasius farm was not efficiently used which predicts that there is a potential of integrated aquaculture farming in aquaculture dominating area. Thus, on-farm action research and development initiatives could be taken in this regard through the collaborative efforts of government and non-government organizations.
