“…Monthly relative humidity ranges from 65–78%, depending on the season and time of the day. For the period from 1995–2009, the minimum and maximum air temperatures in the basin are observed as 19 °C and 34 °C, respectively with a mean annual air temperature of around 27 °C and an average annual evaporation rate of between 1200–1900 mm/year ( Muangthong et al., 2012 ).…”

This paper aims to assess changes in the extreme climate indices of the Lower Songkhram River Basin of Thailand under Representative Concentration Pathways (RCPs) scenarios. A linear scaling method was used to correct climate data bias in three Regional Climate Models (RCMs) under RCP 4.5 and RCP 8.5 scenarios. Thereafter, extreme climate indices related to temperature and rainfall were analysed for the wet and dry seasons in upstream and downstream areas of the basin. A total of 14 climate indices were analysed for three time periods: the 2030s (2020-2044), 2055s (2045-2069), and 2080s (2070-2094) and compared with the baseline climate from 1980-2004. The results show that considerable variability is expected in the extreme climate of the basin in future. The average annual and monthly maximum and minimum temperature is projected to increase, with a lesser increase in the near future and higher in the far future. Heat events (TXx, TXn) are projected to increase while the cold events (TNx, TNn) are projected to decrease in both dry and wet seasons upstream and downstream of the basin. The future average annual rainfall in the basin is projected to decrease under RCP 4.5 and RCP 8.5 scenarios for all three periods. However, the variability in average monthly rainfall is expected to increase in the dry season (Jan-May) and decrease in the wet (Aug-Dec). The most intense rainfall in one day (RX1Day) and five consecutive days (RX5Day) in the wet season is observed to increase in future, with a higher increase in the near future and a lower increase in the far future. The very heavy rainfall days (R20) (the number of days receiving more than 20 mm/day in the basin) are observed to decrease in both wet and dry seasons under RCP 4.5 and RCP 8.5 scenarios in both locations. The results of this study will be helpful for the planning and management of natural resources as well as disaster risk reduction in the Lower Songkhram River Basin.

“…If most wetland ecosystems are not carefully managed, their integrity and the various functions on which humanity depends will be disrupted (Zhou et al 2008; Muangthong et al 2012). Theories and methods of wetland restoration, reconstruction, and evaluation of its effectiveness have been and still are hot topics for wetland environmental research (Stokstad 2005; Li et al 2010).…”

One of the challenges for managers is to ensure the long‐term sustainability of wetlands by protecting their ecological values against natural and human pressures. This study has evaluated the past vulnerability status of Gavkhooni International Wetland, Isfahan, Iran, using a combination of GIS and multicriteria spatial decision support systems (MC‐SDSS) processes, to propose restoration scenarios. Three scenarios were developed from criteria established using field studies and expert opinion: (1) wetland restoration to preserve existing water bodies, (2) determination of susceptible regions as habitat replacement for aquatic communities, and (3) a combination of the two previous scenarios. Finally, a map was developed classifying the regions into five categories by area of priority. The northern regions of the wetland were prioritized based on the results of the first and the second scenarios. The third scenario provided the highest opportunity to obtain an optimistic state, that is, normal conditions, for the wetland marginal regions, especially in the central region (between the east and west). In a pessimistic state and optimistic state of the third scenario, almost all parts of the center to the south of the wetland show the lowest priority restoration scenarios. According to the different scenarios, the central regions of the wetland are less affected by agricultural activities and human settlements. In general, the results show that the Gavkhooni Wetland is unstable based on functional, environmental, social and economic conditions. According to the criteria and the MC‐SDSS model, the government can adopt and implement the necessary policies and programs to improve the condition of the wetland.

“…These data are essential for the success of efforts to determine effective ways to balance the relationship between human activities and preservation of land resources (Sairinen 2004;Hudson et al 2006;Dai et al 2012;de Freitas et al 2013;Gao et al 2013;Lin et al 2013). Wetlands provide essential habitat for wildlife, improve water quality and regulate biogeochemical cycles (Howard-Williams 1985;Gren et al 1994;Woodward & Wui 2001;Brander et al 2006;Mitsch & Gosselink 2007;Muangthong et al 2012;Xie et al 2012;Kaffashi et al 2013;Li et al 2013). Plateau wetlands are of particular importance (Li et al 2013).…”

Land-use/land cover changes and their driving forces around wetlands in Shangri-La County, Yunnan Province, China

The Shangri-La County of the Yunnan Province, SW China, is an economically and ecologically important area. This is especially true for Jiantang that is famous for the Napahai, Bitahai and Shudu Lake wetlands. However, continuing development has threatened the wetland ecosystems and the associated biodiversity in these areas. To better document such changes in land use and their effect on the ecosystem, land use was mapped using a time series of satellite images acquired in 1974, 1993, 2000 and 2012. The results of this survey suggest that forest cover first decreased and then increased. The most obvious changes occurred in cultivated and developed land types, each expanding 1.6× and 17.6×, respectively. Population growth, and previous large-scale deforestation, converting cropland to forest and grassland project, and tourism development were the main socio-economic driving forces. It was also apparent that the rapid development of the tourism industry played a key role in the land-use change, especially after 2000. These data suggest that some regulation to the region's tourism industry and implementation of a sustainable land management policy should be considered to ensure preservation of the Jiantang wetlands.
