FIELD INVESTIGATIONS AND THE SYSTEM WORK

Brief information about the lake

  On 18 February 1911, a powerful earthquake caused a massive rockslide (approximately 2.0–2.2 km³) from Mount Muzkul, which blocked the course of the Murghab River. This event created the Usoy Dam and Lake Sarez.

Research Objectives at Sarez Lake

  • Monitoring of deformation processes in the lake basin’s earth crust..
  • Study of water filtration processes through the Usoy Dam.
  • Analysis of the lake water balance.
  • Study of the hydrological and hydrochemical characteristics of the lake water.
  • Assessment of the impact of climate change on the lake water level.
  • Forecasting the risk of floods and natural hazards associated with ecological changes in the area.

Expeditions

 

Research Aim:

  • Investigation of pasture degradation in Tajikistan

  •  

    Study of the effects of nitrogen deposition on the structure and functioning of pasture ecosystems at different altitudes

  • Assessment of the dynamics and productivity of various pasture types in Tajikistan

Study Outcomes  

  • N significantly increased aboveground biomass, confirming the primary limiting nutrient, while P enhanced productivity mainly when combined with N, especially at high elevations.
  • Precipitation strengthened fertilization effects by increasing biomass and species richness but reduced community evenness.
  • Temperature had little effect on biomass but strongly influenced biodiversity patterns.
  • Overall, moderate and climate-adaptive N and N+P management is essential to improve productivity while maintaining ecosystem resilience.
