The Future of the Koshi Basin: 

A visual presentation of the transboundary basin

How much do we really know about one of the Himalaya’s most significant basins? What are the challenges that millions of people who depend on the Koshi Basin for water and their livelihoods face? What are the climatic threats to the basin, and what are the solutions?

Knowing the answers to these questions is crucial, especially for key stakeholders – from the people at the community level, to development practitioners, policy makers, and journalists – so that important knowledge is shared, and action policies are made and implemented on the ground.

The Koshi Basin Programme’s (KBP) new infographic highlights important details of the Koshi River Basin – its current status, and what is in store for the future. This significant basin and the services it provides are shared by the people of China, India, and Nepal. Millions depend on the Koshi Basin for water, ecosystem services, and livelihoods.

The predicted climate and water scenarios for the 2050s represented here have been obtained from the statistical downscaling of two representative concentration pathways (RCPs), RCP4.5 and RCP8.5 . 

Hydrological simulations were carried out by ICIMOD KBP. The potential of infrastructure development for storage and power generation was investigated using a water evaluation and planning system adopted by ICIMOD KBP. 

This infographic, designed and implemented by the ICIMOD Koshi Basin Programme, contributes to the Sustainable Development Investment Portfolio, and is supported by the Australian aid program.

 i RCPs are four greenhouse gas concentration (not emissions) trajectories adopted by the IPCC for its fifth Assessment Report (AR5) in 2014. The pathways are used for climate modeling and research. They describe four possible climate futures depending on how much greenhouse gases are emitted.
