KATHMANDU — As Nepal expands highways, railways and power lines across the country, a new nationwide study warns the infrastructure boom is cutting through habitats and movement routes used by threatened species. The mapping study, published by WWF Nepal, identifies 515 “biodiversity important areas” (BIAs) and finds extensive overlap between those landscapes and the sites of existing or planned infrastructure projects. A total of 6,529 kilometers (4,057 miles) of roads and 4,862 km (3,021 mi) of power lines already pass through these areas. Nearly a quarter of Nepal’s proposed railway network could also cut across them once completed. The findings sharpen a growing policy dilemma for Nepal: how to build the transportation and power networks needed for economic growth without fragmenting the forests, wetlands and rivers that wildlife depend on, especially outside the country’s protected areas. The BIAs identified in the report fall under 11 categories, including key biodiversity areas, important bird areas, Ramsar wetlands, forest conservation areas, and ecological corridors. Together, they form habitats and ecological zones that allow wildlife to move, breed and survive. Jhamak Bahadur Karki, a former chief warden at Chitwan National Park and faculty member at the Kathmandu Forestry College, who wasn’t involved in the study, said its significance lies in the fact that it highlights biodiversity important areas outside of Nepal’s national parks and wildlife reserves. “The study is eye-opening,” Karki said. “It clearly shows why Nepal needs to pay attention to biodiversity important areas that lie outside protected areas.” Distribution of all infrastructure…This article was originally published on Mongabay
