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.

The GaMampa wetland, a palustrine wetland, comprises less than 1% of the catchment but is widely believed to make a significant contribution to dry-season river flow in the Mohlapitsi River, a tributary of the Olifants River, in South Africa. The contribution of the GaMampa wetland to dry-season flow in the Mohlapitsi River and the impact of increasing agriculture on its hydrological functioning were investigated. Economic analyses showed that the net financial value of the wetland was US$ 83,263 of which agriculture comprises 38%. Hydrological analyses indicated that the Mohlapitsi River contributes, on average, 16% of the dry-season flow in the Olifants River. However, the wetland contributes, at most, 12% to the increase in dry-season flow observed over the reach of the river in which the wetland is located. The remainder of the increase originates from groundwater flowing through the wetland. Furthermore, despite the conversion of 50% of the wetland to agriculture since 2001, there has been no statistically significant reduction in dry-season flow in the Mohlapitsi River. These results highlight the importance of understanding the nature of the full suite of services being provided by a wetland in order to make informed decisions for appropriate management.

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.

The conversion of wetlands to agriculture through drainage and flooding, and the burning of wetland areas for agriculture have important implications for greenhouse gas (GHG) production and changing carbon stocks. However, the estimation of net GHG changes from mitigation practices in agricultural wetlands is complex compared to dryland crops. Agricultural wetlands have more complicated carbon and nitrogen cycles with both above- and below-ground processes and export of carbon via vertical and horizontal movement of water through the wetland. This letter reviews current research methodologies in estimating greenhouse gas production and provides guidance on the provision of robust estimates of carbon sequestration and greenhouse gas emissions in agricultural wetlands through the use of low cost reliable and sustainable measurement, modelling and remote sensing applications. The guidance is highly applicable to, and aimed at, wetlands such as those in the tropics and sub-tropics, where complex research infrastructure may not exist, or agricultural wetlands located in remote regions, where frequent visits by monitoring scientists prove difficult. In conclusion, the proposed measurement-modelling approach provides guidance on an affordable solution for mitigation and for investigating the consequences of wetland agricultural practice on GHG production, ecological resilience and possible changes to agricultural yields, variety choice and farming practice.

This study presents a new global baseline of mangrove extent for 2010 and has been released as the first output of the Global Mangrove Watch (GMW) initiative. This is the first study to apply a globally consistent and automated method for mapping mangroves, identifying a global extent of 137,600 km 2 . The overall accuracy for mangrove extent was 94.0% with a 99% likelihood that the true value is between 93.6–94.5%, using 53,878 accuracy points across 20 sites distributed globally. Using the geographic regions of the Ramsar Convention on Wetlands, Asia has the highest proportion of mangroves with 38.7% of the global total, while Latin America and the Caribbean have 20.3%, Africa has 20.0%, Oceania has 11.9%, North America has 8.4% and the European Overseas Territories have 0.7%. The methodology developed is primarily based on the classification of ALOS PALSAR and Landsat sensor data, where a habitat mask was first generated, within which the classification of mangrove was undertaken using the Extremely Randomized Trees classifier. This new globally consistent baseline will also form the basis of a mangrove monitoring system using JAXA JERS-1 SAR, ALOS PALSAR and ALOS-2 PALSAR-2 radar data to assess mangrove change from 1996 to the present. However, when using the product, users should note that a minimum mapping unit of 1 ha is recommended and that the error increases in regions of disturbance and where narrow strips or smaller fragmented areas of mangroves are present. Artefacts due to cloud cover and the Landsat-7 SLC-off error are also present in some areas, particularly regions of West Africa due to the lack of Landsat-5 data and persistence cloud cover. In the future, consideration will be given to the production of a new global baseline based on 10 m Sentinel-2 composites.

Irrigated agriculture and inland fisheries both make important contributions to food security, nutrition, livelihoods and wellbeing. Typically, in modern irrigation systems, these components operate independently. Some practices, commonly associated with water use and intensification of crop production can be in direct conflict with and have adverse effects on fisheries. Food security objectives may be compromised if fish are not considered in the design phases of irrigation systems. The 2030 Agenda for Sustainable Development provides a framework that can serve as a backdrop to help integrate both sectors in policy discussions and optimise their contributions to achieving the Sustainable Development Goals (SDGs). Inland fisheries systems do play an important role in supporting many SDG objectives, but these contributions can sometimes be at odds with irrigated agriculture. Using case studies of two globally important river catchments, namely the Lower Mekong and Murray–Darling basins, we highlight the conflicts and opportunities for improved outcomes between irrigated agriculture and inland fisheries. We explore SDG 2 (Zero Hunger) as a path to advance our irrigation systems as a means to benefit both agriculture and inland fisheries, preserving biodiversity and enhancing the economic, environmental and social benefits they both provide to people.

Part 1 of this review synthesizes recent research on status and climate vulnerability of freshwater and saltwater wetlands, and their contribution to addressing climate change (carbon cycle, adaptation, resilience). Peatlands and vegetated coastal wetlands are among the most carbon rich sinks on the planet sequestering approximately as much carbon as do global forest ecosystems. Estimates of the consequences of rising temperature on current wetland carbon storage and future carbon sequestration potential are summarized. We also demonstrate the need to prevent drying of wetlands and thawing of permafrost by disturbances and rising temperatures to protect wetland carbon stores and climate adaptation/resiliency ecosystem services. Preventing further wetland loss is found to be important in limiting future emissions to meet climate goals, but is seldom considered. In Part 2, the paper explores the policy and management realm from international to national, subnational and local levels to identify strategies and policies reflecting an integrated understanding of both wetland and climate change science. Specific recommendations are made to capture synergies between wetlands and carbon cycle management, adaptation and resiliency to further enable researchers, policy makers and practitioners to protect wetland carbon and climate adaptation/resiliency ecosystem services.
