Wetlands are amongst the earth’s most productive ecosystem and directly and indirectly support millions of people by providing ecosystem services or benefits, many through maintenance of the hydrological system. Land use changes in developed and developing countries are resulting in gradual elimination of wetlands at global and regional scales. Moreover, anthropogenic pressure to convert wetlands for other land uses is reported to be increasing significantly from developing countries. The Convention on Wetlands is an international initiative that provides a framework for wetland inventory, assessment, monitoring and wise use worldwide. In support of the Convention a multi-scalar wetland inventory was developed by IWMI. At the global level, the distribution of Ramsar sites has been analysed, focusing on the role and impact of agriculture activities. At the regional scale, the role of geospatial data sets has been tested for identifying wetlands in India. In addition a multiple-scale site analysis, using earth observation data and GIS, is underway to detect trends in wetland use for a coastal lagoon-marsh wetland complex in Sri Lanka and for the inland fresh water Lake Kolleru, India. For the regional analysis, two different datasets viz., national wetland inventory data (from SACON-30m) and GIAM (Global Irrigated Area Map-500 m) were used. The preliminary analysis reflects 57 % overlap in wetland area for Gujarat and 10 % for Tamil Nadu. The geospatial change analyses (studied using IDRISI-Andes) in Sri Lanka reflect the loss of deep water lagoon(5%), littoral forest (2 %.) and marsh (1%) due to sedimentation, infilling, vegetation clearance and expansion in built up areas; hence identifying urban development, pollution and the population pressure as the primary ‘indicators of stress’. In Kolleru, the temporal spatial analysis addresses the balance in conservation measures and livelihood dynamics. We intend to integrate the biophysical and socio-economic parameters to explain the role of earth resource satellite data and geospatial tools for sustainable management of wetland systems.

My study aims to investigate the key socio-economic and policy factors influencing the sustainability of natural resource based livelihoods in rural coastal households. While I adopt a sustainable livelihoods approach as an overall conceptual framework, I focus specifically on two aspects of livelihood security - food security and personal wellbeing. I investigate the usefulness of using a combination of food security and personal wellbeing indices that I develop together with other standard qualitative tools, to highlight aspects of livelihoods sustainability that are not covered by conventional poverty approaches. I also apply these approaches to assess first, how certain coastal zone management policy processes such as Special Area Management (SAM) has affected rural coastal livelihoods, and later, to assess the impact of the Asian tsunami on coastal communities and their livelihoods. SAM is a co-management approach applied in specific coastal sites. I collected data from two SAM sites - Rekawa and Kalametiya, on the south coast of Sri Lanka. I collected data from a total of 210 households that covered 6 villages (3 villages in each site). A combination of participatory methods and conventional surveys methods were used. I first examined the major qualitative trends and influences, and thereafter investigated the differences between households within and between villages and between male and female respondents using univariate analyses. Finally, regression analyses were used to relate the food security and personal well-being indices to a number of explanatory variables such as location of village, wealth rank, livelihood activities and SAM participation. My findings suggest that in terms of coastal resource management initiatives, the use of indices and tools such as those developed under this study, could prove to be useful in respect to better targeting the poorer groups among coastal communities. This in turn would contribute towards the overall success and long-term sustainability of coastal zone management initiatives.

The present study highlights the uncertainties that govern wetland management using the Kolleru Wetland case study. The largest fresh water lake and an Ramsar site of international importance it has circled around over past half century from being a fresh water balancing reservoir to agriculture land and shifting as a aquaculture treasure island and lastly ceasing to the aquaculture demolition vis’-a-vis’ restoration conflict in 2007. As nearly all stopovers of this journey was driven by policy shift that demanded economic benefit while surpassing ecological and social community growth. We hereby discuss the event and the analysis of the present state of affairs also spotlighting the major concerns on multiple fronts.

Risk factors in relation to human deaths and other tsunami (2004) impacts in Sri Lanka: the fishers’-eye view. Aquatic Conservation: Marine and Freshwater Ecosystems, 19:57-66. [doi: https://doi.org/10.1002/aqc.996]

This study examines the perceptions of 500 Sri Lankan fishers about influences on the outcome of the 2004 Asian tsunami. It is based upon analysis of questionnaire data on 13 natural environmental and development risk factors, in relation to human deaths and house damage (impact indicators).Mangroves, coral reefs and sand dunes afforded protection against tsunami damage (67–94% of fisher responses), as did housing and roads.Fishers overall believed rivers/estuaries, concave coastlines and hotels exacerbated impacts. However, a significantly greater proportion of fishers living within 100m of the coast reported that rivers/estuaries had a protective role than those living further inland. Rivers seemingly diverted ‘tsunami water’ far inland, where it overflowed and caused damage.Risk and damage are multi-faceted concepts and measurable in different ways. Findings are considered in the light of ecological studies and modelling, with special reference to mangroves, whose alleged protective role has become equivocal during post-tsunami research.Insights of fishers and other communities with intuitive knowledge add a valuable perspective to the understanding of natural disasters and environmental change. This approach is seen as complementary rather than an alternative approach to purely ‘scientific’ research.

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.

This study examines changes in frigate tuna populations in southern Sri Lanka, based on reports from fishers in three age classes. Significantly higher values for best day’s catch and largest specimen ever caught were obtained by older fishers than younger ones. Values were also significantly higher during early years, providing clear evidence of a decrease in the resource over time (1951–2007).Older fishers reported best catches further inshore and in shallower waters which, on becoming depleted, forced younger generations to fish in less exploited areas further offshore. Heavy harvesting is also evident from the significantly greater number of sites reported by older fishers as being depleted, compared with observations of younger fishers.These findings contrast markedly with catch and catch per effort patterns from statistics for frigate tuna and bullet tuna (combined) in southern Sri Lanka (1994–2004). No stock decline is evident, and at least one report in the early 1990s advocated increasing exploitation rates by 40% to maximize yields.Although not a primary research objective, fisher observations on frigate tuna populations were also analysed to help evaluate possible effects of the 2004 tsunami. Most fishers reported post-tsunami decline, but mainly from a larger new generation of fishers, rather than extra boats provided by aid money or (direct or indirect) biophysical impacts from the tsunami.Reliance on fishery statistics, especially for mixed species and over a limited period, can be risky and easily mask true stock status. Evidence of harvesting effects on frigate tuna in southern Sri Lanka is evident using questionnaire data over a longer time scale.This study provides another compelling case of the ‘shifting baseline syndrome’, whereby fishers of different ages have altered perceptions/experiences of their environment. This may be its first reported occurrence in Sri Lanka. Traditional knowledge from this and similar surveys may provide national fishery management with valuable insights and help improve conservation prospects for frigate tuna and other marine resources.

Wetlands are habitats with temporary or permanent accumulation of water. The degradation and loss of wetlands is more rapid than that for other ecosystems, and wetland-dependent biodiversity in many parts of the world is in continuing and accelerating decline. They have been confirmed to deliver a wide range of critical and important services vital for human well-being. Therefore, it is clear that sound wetland management is now expected to not only consider conserving the ecological integrity of the ecosystem but also to pay specific attention to the well-being of local people, thereby contributing to poverty alleviation. Wetlands, both fresh and marine, have a multitude of benefits, in addition to environmental benefits, such as for agriculture, flood control, water purification, fisheries and recreation. For the maintenance and sustainability of wetlands the crucial requirement is water – a resource that has multiple demands and competition. The main competitor for the water resource around the world is agriculture for food production, a basic requirement for human survival. Therefore, in a situation of wetlands versus food production, the balance tips towards food production without considering the adverse consequences to the wetlands or adequately appreciating the benefits from achieving a balance. This is where Integrated Water Resource Management (IWRM) should be adopted to facilitate this process and enable wetland management and agricultural management to fit into the picture along with the other multiple uses of water. Integrated Water Resource Management should be of considerable interest for Sri Lanka, being a country which has agriculture very high on the agenda. The country is also home to a range of wetlands including 103 distinct river basins and 42 lagoons, which support a multitude of functions and services to people. The relationship between agriculture and wetlands in Sri Lanka is complex. The proliferation of village level water storage structures (small tanks) has created an unusually large number of man-made wetland habitats that add significantly to the natural wetlands that are concentrated mainly in the coastal belt. The absence of an integrated approach to water resource development however, continues to erode natural wetland systems. Two major problems, which concern downstream fisheries and livelihoods, are high levels of agricultural pollution, especially through the excessive use of fertilizers, and modifications to the hydrology. The objective of this paper is to review the work of the International Water Management Institute (IWMI) on wetlands and agriculture in Sri Lanka, to look at the competing water demands between water for wetlands and water required for agriculture, keeping in mind the requirements for nature as well as the sustainability of livelihoods. The paper will address some impacts of agriculture on wetlands, the consequences for livelihoods and the benefits of adopting the IWRM approach, building a case on work carried out in the Kirindi Oya and Bundala wetlands.

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.

In many places, growing population, in conjunction with efforts to increase food security, is escalating pressure to expand agriculture within wetlands. The environmental impact of wetland agriculture can have profound social and economic repercussions for people dependent on ecosystem services other than those provided directly by agriculture. If wetlands are not used sustainably, the functions which support agriculture, as well as other food security and ecosystem services, are undermined. This report synthesizes findings from multidisciplinary studies conducted into sustainable wetland agriculture by IWMI and partners in Africa and Asia. It highlights the value of wetland agriculture for poverty reduction as well as the need for more systematic planning that takes into account trade-offs in the multiple services that wetlands provide.
