“…Owing to these studies involve case-specific criteria and objectives, the results obtained solutions couldn't be adjusted to another cases easily [18]. Malekmohammadi and Rahimi Blouchi [38] considered a process of ecological risk assessment to determine stress factors and responses under ecosystem-based approach. The objective of the study is to provide zoning of wetland ecosystems and a systematic methodology for risk assessment.…”

In recent days, the use of the fuzzy set theory to deal with social complexity has become more attractive as a research area to academics who wish to contribute to sustainable development. The socio-ecological systems are one of the well-known sub-disciplines of social science which is very critical issue to maintain sustainability and this concept basically concerns with the human-environment interactions. These systems involve various stakeholders with different levels of knowledge and experience from diverse social platforms. The basic characteristic of these systems is identified as having high level of uncertainty and incomplete information. The main purpose of this chapter is to demonstrate how to incorporate fuzzy sets theory into social sciences. In this chapter, an illustrative example which consists of a wide variety of social actors is used to evaluate sustainable management options utilizing the extended technique for order preference by similarity to ideal solution (TOPSIS) method for interval valued intuitionistic fuzzy multi-criteria group decision making.

“…"Wetland ecosystems are particularly sensitive to climate change that affects hydrology, biogeochemical processes, plant communities and ecosystem function" [49]. Precipitation and temperature determine the wet or dry local climate, affecting the formation and geographical distribution of runoff [50].…”

Abstract:Land-cover and land-use change (LCLUC) alters landscape patterns and affects regional ecosystems. The objective of this study was to examine LCLUC and landscape patterns in Ebinur Lake Wetland National Nature Reserve (ELWNNR) and Ganjia Lake Haloxylon Forest National Nature Reserve (GLHFNNR), two biodiversity-rich national nature reserves in the Ebinur Lake Watershed (ELW), Xinjiang, China. Landsat satellite images from 1972, 1998, 2007 and 2013 were used to calculate the dynamics of a land-cover and land-use (LCLU) transition matrix and landscape pattern index using ENVI 5.1 and FRAGSTATS 3.3. The results showed drastic land use modifications have occurred in ELWNNR during the past four decades. Between 1972Between and 1998Between , 1998Between and 2007Between , and 2007Between and 2013.50 km 2 (7.93%), 122.70 km 2 (3.87%), and 195.40 km 2 (6.16%) of wetland were turned into salinized land. In GLHFNNR both low and medium density Haloxylon forest area declined while high density Haloxylon forest area increased. This contribution presents a method for characterizing LCLUC using one or more cross-tabulation matrices based on Sankey diagrams, demonstrating the depiction of flows of energy or materials through ecosystem network. The ecological landscape index displayed that a unique landscape patches have shrunk in size, scattered, and fragmented. It becomes a more diverse landscape. Human activities like farming were negatively correlated with the landscape diversity of wetlands. Furthermore, evidence of degraded wetlands caused by air temperature and annual precipitation, was also observed. We conclude that national and regional policies related to agriculture and water use have significantly contributed to the extensive changes; the ELWNNR and GLHFNNR are highly susceptible to LCLUC in the surrounding Ebinur Lake Watershed.

“…MCDM methods incorporate concerns about multiple conflicting, complex factors and sub-factors in management planning processes (Liu, 2007). Malekmohammadi and Blouchi (2014) studied ecological risk assessment applying MCDM and Geographic Information system (GIS) and subsequently developed zoning maps to identify and analyze the risky stress factors. The best method to evaluate problems that involve a number of uncertain factors are Analytical Hierarchy process (AHP) (Saaty, 1980) and Analytical Network process (ANP) (Saaty, 1996).…”
