The loss of peri-urban wetlands is a major side effect of urbanization in India in recent days. Timely and proper assessment of wetland area change is essential for the conservation of wetlands. This study follows the integrated way of the peri-urban wetland degradation assessment in the case of medium and small-size urban agglomerations with a special focus on Chatra Wetland. Analysis of land-use and land cover (LULC) maps of the past 28 years shows a decrease of 60% area of the wetland including marshy land. This has reduced the ecosystem services value by about 71.90% over the period 1991–2018. From this end, The Land Change Modeler of IDRISI TerrSet using the combination of MLPNN and Markov Chain has been used to predict the LULC map of this region. The scenario-based modeling following the LULC conversion and nine explanatory variables suggests the complete loss of this wetland by 2045. However, the authors have also tried to present a future LULC pattern of this region based on an environmental perspective. This proposed map suggests possible areas for built-up expansion on the western side of the city without significantly affecting the environment.

“…The estimated value of this study stood at INR 1200. Meng & Dong (2019) also used Market value approach (MV) to value fishing in Nansi lake, China and the result unravelled that in the local market, the average price of fish was $1.745 × 103/t. The average unit area yield were 31.5 t/sq.…”

Valuing Fishing Activity of the Deepor Beel

The Deepor Beel is one of the large and important riverine wetlands in the Brahmaputra valley of Assam, India. The only Ramsar site of Assam, the Beel is one of the richest biodiversity grounds in the wetland eco-system of the state. The Deepor Beel is the hub of a wide range of organisms. It provides various goods and services directly or indirectly to the villages near to the beel for their livelihood. Despite its contribution to society and ecology as a whole, these goods and services of the Beel are undervalued in the policy provisions. The prime reason for this undervaluation is that most of the goods and services of the Beel are non-marketable and those goods which have direct use-values are never valued in an economic term. To fill the gap partially, this study tries to estimate the direct use values of the Deepor Beel. Among the goods the Deepor Beel provides, fishing can be considered one of the economically significant goods. Fishing provides livelihood directly to 825 households living near the Beel. Therefore, this research tries to estimate the direct use value of fishing in the Deepor Beel. A market price approach is applied to estimate the value of this wetland resource. Net Present Value (NPV) of fishing is also estimated. The total estimated value of fishing is INR 11,64,69,375 per annum. The estimated value of fishing per hectare is INR 29,015.78 per annum. The estimated Net Present Value (NPV) of fishing is INR 97,05,78,125. This valuation is important to draw the attention of the policymakers for resource investment in conserving the Beel for continued benefits.

“…This topic has been ignored in previous studies. Therefore, when objectively measuring the total ESV, it is necessary to consider not only the calculation of ESV for different land types [33,34] but also the reverse impact of urbanization on ESV [35].…”

Study of the spatial connection between urbanization and the ecosystem—A case study of Central Yunnan (China)

et al. 2020

This study provides new perspectives on urban development and conservation by exploring the spatial interaction between ecosystem services and urbanization. Limited studies have discussed the interaction between ecosystem services and urbanization; therefore, in this research, the spatial relationship between ecosystem services and urbanization is explored by taking the urban agglomeration in Central Yunnan as an example, and land-use data and economic and social data from 2009 and 2018 are used to determine the interactive impact of urbanization on the urban ecosystem. It is shown that (1) the spatial distribution of the urbanization level of the urban agglomeration in Central Yunnan has significant regional differences, showing a decreasing trend from the urbanized area to the surrounding areas. (2) Another factor with obvious regional differences is the spatial distribution of ecosystem services, which is similar to urbanization in spatial distribution. This difference is mainly caused by the impact of the urbanization level and the change in land use. (3) The spatial distribution and local agglomeration of urbanization and the ecosystem service value of urban agglomeration in Central Yunnan are very similar, and there is a significant negative correlation between the urbanization level and ecosystem service value. The research results have guiding significance for future urban and ecological development in Central Yunnan city.
