The Rural Livelihoods and Climate Change Adaptation in the Himalayas (Himalica) initiative is aimed at supporting poor and vulnerable mountain communities in the Hindu Kush Himalayan (HKH) region to mitigate and adapt to climate change impacts through collaborative action research and pilot activities. This research and activities will help build the capacity of institutions working on resilience to climate-induced vulnerability, which will subsequently improve the livelihoods of the mountain communities in the HKH. Adaptive capacity can only be attained when the value of the ecosystem services provided by mountain communities to those downstream is understood, maintained, and recognized. ICIMOD organized a five-day regional orientation training on ‘Ecosystem Services Assessment’, in collaboration with local implementing partners, Bird Conservation Nepal and Nabaprabhat Nepal. The training provided a common understanding of ecosystem services assessment, the theoretical aspects of participatory rural appraisal (PRA) tools, and hands-on training, which the participants will be able to apply in their work. The training brought together selected experts, researchers, and policy makers from the region, specifically Bhutan, Myanmar, and Nepal where Himalica is focusing its work.
