Myanmar’s rivers provide a reliable source of water for navigation and irrigation, and support food production and livelihoods. In fact, Myanmar’s freshwater fisheries produce more than 1.3 million tons of fish per year and employ approximately 1.5 million people. While the Irrawaddy and other rivers are critical to maintaining the way of life in Myanmar, harnessing those rivers for hydropower is also a big part of the country’s plans for development and reducing poverty.
This scenario is not unique. For many countries like Myanmar, where only one-third of the population has access to electricity, hydropower presents a compelling opportunity to increase energy supply at low costs and make important contributions to development objectives and water resources management.
Myanmar has ambitious future hydropower development plans that mirror the trends seen globally. Projections show that the world is poised to nearly double hydropower capacity by 2040, building as many hydropower dams in the next 25 years as were built in the previous century.
In a report funded by the United Kingdom’s Department for International Development (DFID), The Nature Conservancy worked with WWF and The University of Manchester to demonstrate a framework that could be applied in Myanmar and replicated worldwide to change the trajectory of water resource development towards a more sustainable path. By adopting system-scale planning and engaging diverse stakeholders, Myanmar has the opportunity to be a leader and global example.
Currently, dams are generally proposed and built one at a time, with little or no understanding of how continued development will ultimately affect river systems and other values. A system-scale approach, which the Conservancy calls Hydropower by Design, seeks to compare alternative development scenarios upfront and identify those scenarios that can most effectively balance energy development with the protection of other social and environmental resources. Additionally, risk to funders could be reduced because the approach identifies potential issues that should be addressed early on, leading to fewer conflicts down the road.
Hydropower can be part of a sustainable energy future if designed and operated in a manner that avoids or minimizes impacts on people and vital river functions. As hydropower development increases around the world, many will be looking to Myanmar to see if it can sustainably develop hydropower while maintaining the other diverse values its rivers provide.
