英文摘要 | Small hydropower (SHP) has a global reputation as a 'green', low-carbon energy source that improves rural livelihoods and contributes to local economic development. In China, SHP has grown rapidly since the early 2000s, particularly in the water-rich provinces in the country's southwest. However, because SHP plants in China are privately-operated and approved by local governments, there is an incentive to construct large, multiple cascade systems to generate as much power as possible. In many areas, this has led to over-development of SHP and associated negative environmental and social impacts. In this paper, we identify the factors that shape geographies of SHP over-development, what we refer to as 'shades' of green energy. We then analyze the direct and indirect impacts of over-development. We draw on interviews and electricity generation data from six prefectures in Yunnan province, one of the world's largest hydropower producing regions. We find that prefectures that operate in a semi-autonomous way in electricity management and industrial planning are most prone to over-develop SHP, since they depend on hydropower revenues from electricity generation and local energy-intensive industries. We also find that over-development of SHP causes streamflow reductions and unstable electricity generation, and in some areas, drives an increase in environmentally-destructive mineral processing and reduces irrigation water access. These findings suggest a need for coordinated river basin planning on small watersheds and a reassessment of the role of SHP in local economic development. |
