Since India gained Independence, the Krishna basin has seen an increasing mobilization of its water resources. Warnings of basin closure (minimal flow to the ocean) emerge during dry periods. Basin water development and local rural dynamics have led to a degradation of downstream ecosystems manifesting itself by salinizing soil and groundwater, increasing pollution, making mangroves disappear, and desiccating wetlands. Reversing this evolution requires the formal recognition of the environment as a water user in its own right and the implementation of an environmental water provision. This provision should be based on a two-tier allocation system with assured discharges in the irrigation canals of the delta and to the ocean. This will lead to further commitment of water resources, but this is needed to reconcile the social, economic, and environmental objectives of sustainable development. Other measures facilitating integrated natural resources management from the local to the basin level are needed too.

Progressive agricultural and water development in the Krishna Basin in South India has led to a rising over commitment of water resources and signs of basin closure are apparent during dry periods. As human consumptive uses are approaching the limits of water availability, this report focuses on the Lower Krishna Basin that bears the brunt of any intervention upstream. Capturing the process of basin closure requires an understanding of the political dimension of access to water and the scope for change. As basin closure intensifies the interconnectedness of ecosystems and water users, adjustments and management decisions result in spatial re-appropriation of water and basin-wide strategies for water management and development that start with the definition and the implementation of water allocation mechanisms are increasingly needed.

This study presents a comprehensive site-scale analysis conducted within the global wetland inventory and mapping (GWIM) project. GWIM was developed and promoted by the International Water Management Institute (IWMI) through global partnerships to investigate wetland analyses at multiple scales. The present study investigates the complexity of an inland freshwater wetland system, presenting a conceptual framework for mapping and monitoring the dynamics of Lake Kolleru (a wetland of international importance, as defined by the Ramsar Convention), utilizing a geospatial platform. Illustrating the pace of land use changes leading to the progressive elimination of the wetland ecosystem of freshwater Lake Kolleru, this study also highlights the impacts of such changes on the socio-economic system. A comprehensive temporal analysis (1977-2007) provided a structural base to schematically analyse the dynamics of biophysical and ecological changes to the wetland by effectively using a spectrum of remote sensing data. The present status and changing trends in ecological dimensions of Lake Kolleru were illustrated, utilizing information from spatial analyses, complimented with socio-economic assessment. Attention is drawn to the potential of utilizing earth resources systems in exploring space-time interactions in freshwater ecosystems heavily modified through aquaculture interventions. Further, the spatial derivatives are meant as reference material for local authorities and decision-makers to rehabilitate the economic livelihood activities to the social community dependent on the lake ecosystem. The disseminated message emphasizes the applicability of geospatial tools to enhance the efficacy of the decision-making process by facilitating regular monitoring of ecosystem dynamics and providing updated information on wetland patterns and uses.

In densely populated coastal wetlands with rich biodiversity, multiple, but generally competing, economic activities are common. This paper adopts a polycentric perspective to the study of wetlands management in India to assess the scope for sustainable and equitable use of these remarkable and threatened ecosystems. The analytical framework proves to be useful and highlights that the intertwined processes of environmental and social changes result from, and shape, governance patterns. The three wetlands studied share commonalities in their trajectories: high population pressure, the enclosure of the commons and subsequent capitalization of resources and social marginalization, conflicting interests and intense local politics, a disconnect between global conservation discourses and local concerns, weak institutional arrangements, and global economic forces. The intense politics of access, control and use of natural resources challenge the implementation of a true polycentric regime in the Indian context due to a tendency to bureaucratization and a lack of participation, and existing limits to democratic citizenship. Creating a democratic space where multiple voices can be considered in the decision-making process remains a challenge. The paper concludes that inclusion of power and politics in the study of governance of natural resources should be of prime concern for researchers and decision makers.

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.

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.
