Impacts of co-management on fish biodiversity and livelihoods of fishers of Baikka beel, Moulvibazar, Bangladesh

Co-management plays a significant role in fisheries and natural resources management. In the case of fisheries, it has most often been taken to mean a sharing of responsibility for sustainable resource management between government and fishing communities. Baikka Beel, situated in Moulvibazar, Bangladesh has been identified and established as a wetland sanctuary by local community members in conjunction with the Management of Aquatic Ecosystem through Community Husbandry (MACH) project. In this study, the role of co-management institutions, including federations of resource user groups (FRUGs) and resource management organizations (RMOs) were investigated on sustainable wetland resource management and fish production and biodiversity in Baikka Beel. Study results shown that the knowledge and attitudes of MACH fishers towards sustainable resource management were positive and optimistic than non-MACH fishers; MACH fishers were involved with AIGAs. The results from independent samples t-test showed that the income of MACH group from fishing was significantly lower than the income of non-MACH group while income from AIGAs of MACH group was significantly higher than the income of non-MACH group. Fishing rights of both MACH and non-MACH fishers are not well established due to current leasing system. Both production and biodiversity of fish has been improved due to community-based sustainable management of Baikka Beel

New vegetation type map of India prepared using satellite remote sensing: Comparison with global vegetation maps and utilities

International audienceA seamless vegetation type map of India (scale 1: 50,000) prepared using medium-resolution IRS LISS-III images is presented. The map was created using an on-screen visual interpretation technique and has an accuracy of 90%, as assessed using 15,565 ground control points. India has hitherto been using potential vegetation/forest type map prepared by Champion and Seth in 1968. We characterized and mapped further the vegetation type distribution in the country in terms of occurrence and distribution, area occupancy, percentage of protected area (PA) covered by each vegetation type, range of elevation, mean annual temperature and precipitation over the past 100 years. A remote sensing-amenable hierarchical classification scheme that accommodates natural and semi-natural systems was conceptualized, and the natural vegetation was classified into forests, scrub/shrub lands and grasslands on the basis of extent of vegetation cover. We discuss the distribution and potential utility of the vegetation type map in a broad range of ecological, climatic and conservation applications from global, national and local perspectives. We used 15,565 ground control points to assess the accuracy of products available globally (i.e., GlobCover, Holdridge’s life zone map and potential natural vegetation (PNV) maps). Hence we recommend that the map prepared herein be used widely. This vegetation type map is the most comprehensive one developed for India so far. It was prepared using 23.5 m seasonal satellite remote sensing data, field samples and information relating to the biogeography, climate and soil. The digital map is now available through a web portal (http://bis.iirs.gov.in)
