“…On the basis of the research by Costanza et al, the Chinese scholar, Xie Gaodi [11] conducted a questionnaire survey in 2002 among 200 professionals with ecological backgrounds, modified the coefficient according to the actual situation of China, and obtained the land ecosystem service value with China as the scale. This method has the advantages of simple use, less data demand, high comparability of results and comprehensive evaluation, and thus it is used in the study of regional ecosystem service value evaluation in China [12,13,14,15,16]. However, this method provides the unit price of the average ecosystem service value in China, and the ecological service value of the ecosystem is closely related to the region’s natural environment and social and economic conditions.…”

Land use change has an impact on the ecosystem service value because it changes the structure and function of ecosystems. This paper analyzed the changes in land use during the period from 2000 to 2015 in Shangzhou district, and used the equivalent value of ecological services per unit area of land ecosystem combining the natural and economic conditions of Shangzhou district. Based on this method, the ecological service value of Shangzhou district was estimated, and the impact of land use change on the ecological service value was analyzed. The results showed that: (1) the main types of land use in Shangzhou district were grassland, woodland and farmland, among which the contribution rate of woodland to the value of local ecosystem services was the highest; (2) the overall trend in the ecosystem service value in Shangzhou district increased between 2000 and 2015, from 10.74 × 108 yuan in 2000 to 20.32 × 108 yuan in 2015, which is the result of the combined effects of regional economic development and changes in the natural environment and land use patterns; and (3) the main reason for the value increase of ecosystem services in Shangzhou district between 2000 and 2015 was that the grain-for-green policy transformed a considerable amount of farmland into woodland, while the main reasons for a decline in value was the expansion of built-up land that occupied other types of land.

“…Benefit transfer carries forward measurement errors inherent in any primary study on which it relies, and should not replace methodical and meticulous on-the-ground study. We note, however, that more robust studies often still rely on estimates, approximations, models, simplifications or secondary valuations [68,79]. Meanwhile, local detailed studies in at least some …”

“…Baseline data and mapping has improved some in recent years with particular emphasis on government remote sensing applications [63], yet these activities have been contested by civil society actors on the grounds that they contain politically motivated flaws [64]. Although not a commonplace method, ES study and valuation has been conducted in a variety of Indian cases e.g., [65][66][67][68]; indeed, some Indian data has contributed to the global ES value database produced by the TEEB project [69] used in this paper. Meanwhile, conservation scientists have argued for a long list of overlooked or understudied aspects of marine and coastal ecology and biology in India [70].…”

Abstract:The paradigm of ecosystem services (ES) and the methods of monetary valuation have become boundary objects, spanning disciplines and earning particular purchase in policy circles. However, the notion of ES and ES valuation have also been subjected to multiple critiques, ranging from their varying precision to the potential for neoliberalization of nature. This paper does not attempt to refute such critiques but rather revisits the potentials of the ES paradigm and the specific method of benefit transfer valuation for their utility as a form of environmental politics and sustainability practice. We find they have particular relevance in contexts where "data" are not readily available or are not legible to policy makers as well as where the imperative of "development" remains ideological. We argue for ES assessment and, specifically, rapid ES valuation as a first-pass tactic to inform evaluation of potentially environmentally degrading projects or environmental management. We demonstrate this using a simple benefit transfer analysis to offer an initial evaluation of (wet) landscape ES in a lightly touched estuary in Karnataka, India, where a state-backed proposal to develop an industrial shipping port is gathering steam. While we recognize and do not categorically reject critiques of the ES paradigm, we nonetheless argue for valuation as a starting point for politics that highlight and make visible ES benefits and users implicated by "development" and other kinds of environmental change.

“…Moreover, in the Akkulam-Veli lake, a large amount of city's municipal wastewater enters the wetland untreated through a system of drains due to deficiencies in the sewage collection system (Ghermandi et al, 2016). Leading to high sedimentation rate, which reduce the contact time between organic matter and dissolved oxygen in the water column, and therefore, can contribute to higher concentration of carbon and nutrients in sediment.…”

Aim: To investigate the influence of environmental variables on the abundance and activity of methanogenic archaea (MA) in Akkulam-Veli and Vellayani Lake sediments. Methodology: Sediment and overlying water samples (n=5 each) were collected from Veli and Vellayani lakes of Thiruvananthapuram, Kerala. Samples were analysed for environmental variables using standard protocols. Multivariate analysis was done to study the influence of environmental variables on abundance and activity of MA. Results: Environmental variables of overlying water and sediment showed significant variation between the two lakes. Salinity and sulphate were more in Akkulam-Veli than Vellayani, as Akkulam-Veli is a brackish lake and temporarily connected with Arabian Sea. Highly reduced sediments of Akkulam-Veli favoured more population of methylotrophic and acetoclastic MA than Vellayani. A distributional difference of MA with depth was observed in both lakes, which is attributed to availability of more labile organic matter. The methylotrophic MA activity was not significantly different between the two lakes; however, their abundance was significantly different. Nevertheless, methane production was higher in Vellayani than in Akkulam-Veli Lake. PCA revealed that Corg and labile organic matter (LOM) were the important environmental variables influencing methane production potential. Interpretation: Anthropogenic activities like sewage and waste disposal results in increased input of organic matter in lake sediments. The labile organic matter fraction in the sediments favours methanogenic activity thereby resulting in methane production and release from the lakes. Key words: Labile organic matter, Methanogenic archaea, Methane production, Sulphate reduction, Tropical lakes
