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 Ayeyawardy 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.
 
We evaluated Myanmar’s Myitnge River, a tributary of the Ayeyawardy, and the values it provides for communities, its potential for generating power, and the outcomes that could result from hydropower development. Our results clearly showed that energy development produces tradeoffs with other resources and values. However, there are many different options to increase energy generation and these options very widely in terms of their impacts. A system-scale approach can identify “win-win” or “close to win-close to win” options—these are options that meet energy objectives but minimize negative impacts or have synergistic benefits for other sectors (e.g., navigation). These balanced options are highly unlikely to emerge from a set of project-level decisions. For example, as generally expected, a larger number of dams in the Myitnge sub-basin was projected to increase fragmentation, flow alteration, and sediment and nutrient trapping, thus reducing the sub-basin’s contribution to the overall fish productivity in the Ayeyawardy basin. However, there are several combinations of dams and operating rules that would produce almost the same amount of energy, but with potentially much lower impacts on fish productivity.
 
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 diverse other values its rivers provide.

A neighbor country approach for long term plan associated for electricity generation, irrigation, flood control, drought based irrigation inter-linking. But all it require a very sound institutional frame work of associated countries, their investment scenario (including international soft funding approach with present role off ground situation). Nerveless to the business process profitability including sharing of energy trading with neighbor country.

There's certainly a lot to know about this topic.
I love all of the points you made.

This is awesome information this can reduce energy crisis in world in near future

I did not notice before that only one third of poupilation has access to electricity.So there is tremendous opportunity in energy sector so to hydro.Need simple and supportive buerocratic system and will of the politician other trecnical and financial is not a matter.Could be seen for bright future...

Hi there, its good paragraph regarding media print,
we all be familiar with media is a enormous source of data.
