Study Region: West Rapti River (WRR) basin, Western Nepal.
Study Focus: Hydrologic modeling requires an accurate precipitation data at a high spatial resolution, which is often limited in many regions of the globe. As a complement to the ground (gauge) precipitation data, satellite-based precipitation estimates (SPEs) appear useful. At first, this study evaluated performance of three different SPEs, namely i) CHIRPS, ii) PERSIANN-CCS, and iii) IMERG, with respect to gauge data using different event detection and quantification indices. Soil Water Assessment Tool (SWAT), a semi-distributed hydrologic model, was used to simulate the river discharge. We then analysed precipitation elasticity, as a first kind of such study in Nepalese river basin, by scaling the precipitation input in both positive and negative directions (ranging from -20 % to +20 %) in order to explore basin response on likely alteration of precipitation. A non-parametric precipitation elasticity was finally computed for three different cases: 1) observed river discharge, 2) gauge-based simulated river discharge, and 3) SPEs-based simulated river discharge.
New Hydrologic Insights for the Region:
IMERG proved to be superior among three SPEs. All SPEs showed improved results after implementation of different levels of bias-correction where daily precipitation data were corrected using linear correction factors computed at a mean monthly scale. Computed correction factors are replicable to nearby basins. Precipitation elasticity of the study area ranged from +1.3 to +2.0 (approximately +1.5) which indicates that a 1.0 % change in precipitation will result in 1.5 % change in river discharge.

We reviewed 76 climate change adaptation projects that were operational between 2010 and 2020. The review was followed by office and field visits for verification. The office visit helped crosscheck the findings, and the field observations carried out between December 2020 and April 2021 asked 24 key informants and collected supplementary information appraisal and indicator development. Of the CCA projects studied, the most (n = 48, 32%) were community-based initiatives, while the least (n = 12, 8%) were ecosystem-based interventions. The main environment-centered projects were Ecosystem-based Adaptations and Ecosystems Protecting Infrastructure and Communities (EPIC) while Enhanced Action of Inclusive CSOs for Participation in Climate Resilient Economic Growth (UTHAN), Initiative for CCA (ICCA), Support to Rural Livelihoods and Climate Change Adaptation in the Himalayas (HIMALICA), etc., adaptation projects were community-based. Capacity building and awareness-raising were the major thrust of the CbA projects, while the abatement of climate vulnerabilities and risks through nature-based solutions were priorities of EbA. Payment for Ecosystem services is a nature-based solution that can play a role in enhancing adaptation to climate change at a local scale by adopting community-based and culturally appropriate methods and enhancing and incentivizing adaptation measures and capacities. A set of 11 criteria and 40 indicators comprised the institutional and behavioral responses and the use of technologies, and the design of climate-resilient plans and climate-smart practices were proposed as appraisal measures to evaluate the success of CCA interventions. The importance of criteria and indicators lies in the fact that such a comprehensive assessment would lead to effective and efficient adaptation projects, which could help benefit beyond the borders. It also furthers ongoing adaptation interventions and is set to be an integral part of associated studies and monitoring and review of new adaptation interventions.
