Assessment of mangrove management alternatives in village-fringe forests of Indian Sunderbans: resilient initiatives or short-term nature exploitations?

Abstract

The village-fringe mangroves throughout the Indian Sunderbans have become ecologically fragile due to decades of unsustainable utilization practices and changes in hydro-geomorphic conditions. These mangroves are generally managed by the state-run Forest Department, community institutions and non-governmental organizations either separately or in collaboration. This paper attempts to assess the forest health of three such mangrove sites managed by these different institutions using quantitative vegetation surveys. Transformations of land use and land cover patterns of these sites from 2003 to 2013 have also been analyzed by geospatial techniques. Moreover, a qualitative estimation of the products and services provided by these mangroves was performed through participatory appraisals among the local forest dependents to comprehend the level of economic sustenance achieved. Results indicate that the overall performance of the site managed by a non-governmental organization in collaboration with local forest dependents was better than the other two sites managed by Forest Department and joint state-community institution respectively. Proper recognition of the causes of forest degradation and subsequent creation of zonal plantations with respect to species associations and utilization patterns were identified as the prime determinants of comparative success of the former site. Restructuring of community institutions by strengthening participation of actual forest dependents in decision making was suggested to be beneficial for mangrove restoration of sites performing poorly. In general, adaptation of collaborative approaches towards addressing the issues of tenure rights, legitimate sharing of mangrove produces and services, conflict resolutions among and within these institutions were found to be imperative for resilient management of these mangroves.
