“…The high carbon loss per unit crop yield in the tropics results from two factors: the overall highest average carbon loss from conversion and the lowest average crop yields. Tropical peatlands are among the most carbon-rich ecosystems in the world, typically storing more than 1000 t ha −1 (191 Gt, or one-third of all carbon in peatlands globally [27]); preserving those peatlands would prevent a great amount of carbon emissions.…”

Trade-Offs in Multi-Purpose Land Use under Land Degradation

et al. 2017

Land provides a host of ecosystem services, of which the provisioning services are often considered paramount. As the demand for agricultural products multiplies, other ecosystem services are being degraded or lost entirely. Finding a sustainable trade-off between food production and one or more of other ecosystem services, given the variety of stakeholders, is a matter of optimizing land use in a dynamic and complex socio-ecological system. Land degradation reduces our options to meet both food demands and environmental needs. In order to illustrate this trade-off dilemma, four representative services, carbon sinks, water storage, biodiversity, and space for urbanization, are discussed here based on a review of contemporary literature that cuts across the domain of ecosystem services that are provided by land. Agricultural research will have to expand its focus from the field to the landscape level and in the process examine the cost of production that internalizes environmental costs. In some situations, the public cost of agriculture in marginal environments outweighs the private gains, even with the best technologies in place. Land use and city planners will increasingly have to address the cost of occupying productive agricultural land or the conversion of natural habitats. Landscape designs and urban planning should aim for the preservation of agricultural land and the integrated management of land resources by closing water and nutrient cycles, and by restoring biodiversity.

“…Tropical floodplain wetlands provide numerous ecological services through regulation of hydrological cycle, facilitation of groundwater recharge, controlling flood risk by modifying the river discharge, and support diverse livelihood activities (Costanza et al 1997;Tockner and Stanford 2002;Murphy et al 2003;Mitsch and Gosselink 2015). They are also one of the most carbon-rich ecosystems storing~250 Gt of carbon (Neue et al 1997;Bernal and Mitsch 2013;Kolka et al 2016). Particularly, seasonal floodplain wetlands act as a significant carbon sink by sequestering vast amounts of organic carbon in soil and vegetation ranging from 69.2 to 114.3 g C m −2 year −1 , that could help in mitigating the impact of climate change (Walling et al 2006;Cierjacks et al 2010;Sutfin et al 2016;Craft et al 2018).…”

“…The carbon stocking capacity of wetlands is modulated by various environmental factors such as climate, hydrology, soil, vegetation, land conversion, and management practices (Adame et al 2015;Kolka et al 2016;Watkins et al 2017). The effect of these factors may be understood at various spatial, e.g., local, regional, and global, and temporal frames of reference, e.g., ten to hundreds of years (Carnell et al 2018).…”

“…The effect of these factors may be understood at various spatial, e.g., local, regional, and global, and temporal frames of reference, e.g., ten to hundreds of years (Carnell et al 2018). Nevertheless, to design and implement effective management strategies, it is necessary to understand how the proximal abiotic factors influence the pattern and mechanism of carbon stocking in tropical wetlands (Mitra et al 2005;Kolka et al 2016).…”

Variation in species assemblages due to micro-topography and flow regime govern vegetation carbon stock in seasonal floodplain wetlands

2019

Hypothesis: Variation in species assemblages due to micro-topographic features and flow regime determine vegetation carbon stock in floodplain wetlands.Material and method: We tested this hypothesis in Chatla-a tropical floodplain wetland located in northeast India. Five sampling stations characterized by contrasting micro-topographic and flow parameters were selected in the wetland for study. Species composition, assemblage pattern, and vegetation carbon stock were studied in these stations during three flood phases, i.e., early, middle, and late flood phases following standard methods. Univariate and multivariate statistics were used to determine the relationship between the selected environmental parameters, plant species assemblages, and vegetation carbon stock of the wetland.Results: Thirty-one species of herbs and five species of shrubs were recorded from the five stations in Chatla floodplain wetland. Flow regime characterized by water flow velocity and discharge showed substantial variations across the stations. These parameters in turn are related to variations in the micro-topographic characteristics namely depth, width, and cross-sectional area of the stations. Plant species composition and abundance differed significantly with respect to micro-topography and flow regime as revealed by the cluster diagram. The canonical correspondence analysis revealed strong association of plant species assemblages with the micro-topography and flow regime within the wetland. Multiple regression analysis revealed a significant positive relationship of the vegetation carbon stock with the water discharge. Conclusions: Spatial variation in plant species diversity because of micro-topography and flow regime determines the vegetation carbon stock in floodplain wetlands. Modification of these parameters by anthropogenic activities such as mining and quarrying may potentially influence the carbon stocking potential of seasonal floodplain wetlands. Therefore, appropriate measures should be taken to maintain the integrity of the natural topographic features of such wetlands.

“…They occupy about 8% of the world's coast and 25% of the tropical coastline (Selvam et al 2003) accounting for about 0.7% of the world's tropical forest area (Donato et al 2011;Kolka et al 2016). South and Southeast Asia has the most extensive and diverse mangrove systems representing about 41.4% (Singh et al 2012) of the total 15.236 million hectares (Mha) of the global mangrove area (Spalding et al 2010).…”

Monitoring of Eco-Restoration of Mangrove Wetlands through Time Series Satellite Images: A Study on Krishna-Godavari Delta Region, East Coast of India

et al. 2017

Comparative analysis of time series satellite images spread over the past four decades indicated significant changes in the mangrove environment of the Krishna-Godavari twin deltas along the east coast of India. We analyzed Landsat-MSS, TM and ETM images from 1977, 1990, and 2000, respectively, and Indian Remote Sensing Satellite images from 1992, 2001, and 2013, which indicated that the mangrove cover in the region increased from 35,058 ha in 1977 to 39,283 ha by 2013. In spite of loss of mangrove vegetation over 8,036 ha due to coastal erosion, deforestation, decline and aquaculture encroachments, several mangrove-restoration projects taken up during 1991-2008 led to an overall increase in its area. Various mangrove eco-reforestation techniques were adapted in the region.
