Floodplain areas along the Naryn River in Kyrgyzstan : assessment of hydrological and climate changes, and its dynamics

In this paper, to study the floodplains along the Naryn River they have been selected two investigation areas in the distance and nearby of settlements, in case Emgek-Talaa and Ak-Tal villages of Naryn region in Kyrgyzstan. We analyse anthropogenic impacts on these areas and ecosystem services provided by flood-plain forests in a comprehensive way including ecosystem structures. Floodplain areas deliver multi-functional services as forest, pasture land, habitats of plant and animal species, and also as resting place for local people. The methodology contains exploration of the study the landscape changes of the investigation areas by using remote sensing and GIS. The climatic conditions for the investigated area, as well as the magnitude and frequency of annual, monthly and daily water discharge of surface runoff and also groundwater level of the Naryn River were investigated. Increasing temperature and climate variability, flooding and drought, alteration of intensity of precipitation and melting glaciers in high mountain areas affect the physical condition of natural resources. Climate change might cause larger and potentially hazardous summer floods. Due to the highly dynamic flow conditions of the Naryn River, this enhances water erosion especially of the river banks. Conservation and restoration of riparian forests is important for strengthening river banks and preserving biodiversity. We elaborate recommendations for the communities. Reducing negative impacts of climate change and mitigating anthropogenic influences on ecosystems should be a priority task building upon the involvement of stakeholders
