Regular monitoring of wetlands is an essential element of management for 'wise use'. Indeed, the Ramsar convention requires routine monitoring in order to detect changes in the ecological character at listed sites. However, there are few examples of monitoring of tropical wetlands on a sustained basis in the world. In the present study, we quantified land use/land cover changes in the lone Ramsar site, the Kolleru Wildlife Sanctuary of Andhra Pradesh, India between 1977 and 2007 using remote sensing and GIS techniques. It was found that there was a significant increase in aquaculture farming (158.5 sq km) from 1977 to 2000, which put the habitat of flora and fauna in adverse conditions. The natural function of lake was being restored after the demolition of fishponds ordered by the Honorable Supreme Court of India it 2006. This study highlights the firsthand information to the user community after demolition, and offers suggestions for the future conservation of the lake. We suggest that remote sensing and GIS tools have a significant role in meeting the reported requirements for the CBD 2010 target.

This paper highlights the dynamics between land use changes in the Kolleru Ramsar wetland and local livelihood systems and explains these through the lense of national policy responses and international (Ramsar) obligations. A multi-disciplinary approach was adopted by integrating geospatial tools and techniques with policy and livelihoods analysis. The findings show a temporal transfer of policy motives underpinning key land use changes, from agriculture supporting local livelihoods (up to the late 1970's) to maximizing economic values of land through commercial aquaculture (1980's-1999), and finally to ecological restoration and protection (1999 onwards). Each land use change brought new challenges at the local scale. Socio-economic assessments revealed that the demolition of aquaculture ponds (2006) prompted changes in livelihood strategies. Some households diversified their livelihoods (e.g. fishing)), while compensation packages helped this diversification in some instances. From the policy perspective, this case study illustrates the predominance of in-country/local lobbies over international obligations, in decision making for balancing ecosystem conservation with development.

Ecosystem based approach (EBA) for resource management is a concerted, environmentally tuned and an integrated framework that holistically addresses the ecological character of the natural resource, its societal benefit spectrum and its environmental functions. In this paper, the EBA concept is closely linked with the emerging concept of multiple use systems (MUS) while taking account of environmental, economic, and social factors that govern the ecosystems services and benefits. We elucidate a multi-scalar approach and multiple case studies to understand EBA particularly in context of a wetlandscape. At the global scale, Ramsar sites of international importance are geospatially analyzed with reference to their agro-ecology and biodiversity. At regional scale, the agrarian use of inland wetlands in India was re-evaluated taking account of database from a recent inland wetland inventory. At the local scale, drawing on the landscape characterization and the ecological economics for fresh water Lake Kolleru in India and the Muthurajawela Marsh-Negombo Lagoon coastal marsh in Sri Lanka, we illustrate some of the practical challenges in balancing wetland conservation, development needs and the overall well-being of local people. We also discuss how variability in the scale, geophysical characteristics of the site and the data availability confines the ability to simplify a single complete approach to address issues in complex ecosystem such as wetlands. All levels of the study are supported by a variety of earth observation data and the geographical information system (GIS) tools. The site level analysis also draws on socio-economic assessment tools.

The Muthurajawela-Negombo wetland system in Sri Lanka provides critical ecosystem services for local people. The wetland has, however, undergone considerable ecological change over the past few decades. A multi-scale, inter-disciplinary approach that combined geospatial analyses with livelihoods analyses was used to assess environmental change in the wetland and the impact of this change on local livelihoods. While a geospatial model was used to determine broad changes in land use patterns in the wetland, an in-depth case study covering one village was conducted, using local perceptions to explore the inter-linkages between environmental change and livelihood systems at the household level. The findings of this study suggest that there have been significant changes in the wetland cover/use patterns during the period under investigation and that these changes have been observed and experienced by local communities. There are differences in local perceptions on whether these changes are for the better or worse. This may be linked to whether the land cover types are directly accessed and used in the household livelihood system, and to the geographic location of the land cover types in relation to the village. The findings indicate the usefulness of adopting this type of approach where both conservation and development needs are considered to address environmental concerns and related livelihood issues in wetlands.

Effective implementation of participatory environmental governance faces a number of challenges, including the need for appropriate mechanisms and incentive systems that can operate across multiple-use landscapes. This study demonstrated scenarios for such governance from three agro-ecological zones in different geographical, biophysical and socio-cultural settings: (i) Kedarnath Wildlife Sanctuary in the temperate forests of the Central Himalayas, (ii) Kolleru Lake, a freshwater lake in the Krishna Basin and (iii) the downstream Ganges seasonal floodplains in Bangladesh. The cross-disciplinary set of approaches in these examples involves the use of spatial tools and socioeconomic surveys to build a scenario-based framework with cross-scaling prospects. The comparative analysis between these sites is significant in the context of providing guidance for trans-boundary environmental governance and the underlying challenges that occur in politically complex and common property resource institutional arrangements. Meeting these challenges will assist in the efforts, locally and nationally, to make wise use of all wetlands, as required under the Ramsar Convention on Wetlands. Kedarnath Wildlife Sanctuary symbolizes a case of increasing anthropogenic pressure, limited livelihood options and with gaps in the governance structure. Kolleru Lake represents a case of inadequate understanding of the ecological dimensions of livelihood interventions and the consequential community conflict. The case of floodplains in Bangladesh illustrates the potential of collective action, supported by appropriate institutional arrangements, for improving rice-fish productivity. The case studies support the argument that monitoring and assessment of the resource structure and its dynamics, with the application of geospatial tools, adds value when shaping a framework for policy debate and for ensuring the wise use of wetlands.

The two components of the study reflect assessment and change analysis of a tropical wetland in Sri Lanka. The first section explains spatial classification using pixel level-disaggregated image analysis and refined aggregated image analysis and comparison of information extracted by all methods to analyse a better classifier. The second section illustrates change analysis calibrating the land change modeller (LCM) [IDRISI-Andes]. Key observations: a) visual interpretation provides comprehensive blueprint of the wetlandscape compared to supervised and unsupervised classifiers b) change in landscape pattern reflect substantial transition in wetland use. Validation using field coordinates and socioeconomic data showed kappa value (%) of 87.

A 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. Weused 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 23.5m 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).
