Roundup: Religion, Economic Impacts, and Glacial Recession

Economic Impacts of Climate Change on Himalayan Rivers

From Environment Science and Policy: “In order to quantify the effect of climate changes on hydropower and fisheries, we developed an integrated assessment framework that links biophysical models (positive degree-day model, hydrologic model, run-of-river power system model, and fishery suitability index) and economic models. This framework was used to demonstrate the framework’s utility for gaining insights into the impacts of changed river flow on hydropower and fisheries of the Trishuli River in the High Mountain Asia (HMA) Region.”

Climate, Earth and God

From World Development: “Based on fieldwork in agro-pastoral communities in highland Cusco, Peru, this study examines climate perceptions in terms of how local community members understand and explain changing climatic conditions… For example, Jurt et al. note that some residents attributed the retreat of nearby glaciers to the abandonment of traditional offerings to the mountains (or apus, which have a similar ontological status as pachamama in traditional Andean belief). Bolin suggests that in her study areas, also in the Cusco region, ‘some indigenous people have wondered what they have done wrong to deserve the wrath of the gods.’”

Recession and Future Lake Formation on Drang Drung Glacier

From Environmental Earth Sciences: “Our analysis indicated that Drang Drung glacier shrunk by 13.84 percent from 1971 to 2017. Meteorological projections of temperature and precipitation were used to understand climatic changes over Drang Drung region. The snout of the glacier has retreated by 925 m since 1971 at the rate of 21.11 ma−1. However, the snout retreat radically accelerated since 2014 at 60 ma−1. Analysis of available satellite data suggested that the proglacial lake formed around 2014. The lake has expanded to 16.62 ha in 2017. ”
