Why attempts to ensure water, food and energy security should focus on innovative bottom-up strategies rather than large multipurpose projects

infrastructure projects, the risks for investors, communities, and ecosystems are extremely high given uncertainties in future hydrological conditions". It concluded that "climate-infrastructure mismatches may make poor nations even poorer". Future development strategies need to move away from technologies that depend on stable hydrological conditions. A recent World Bank report warns that "long-lifespan infrastructure, such as hydropower plants, is generally less adaptable to changes in actual facilities." "An adaptation response", the report finds, "may require a policy decision to diversify away from hydropower". The director of the IMF's Africa Department has encouraged East African countries to minimize their "very significant dependence on hydropower". And the authors of the PLoS Biology paper recommend making infrastructure less vulnerable by designing for "multiple potential climate regimes", building in stages to take changing conditions into account, and integrating ecosystems into project designs. Luckily, solutions that integrate water, food and energy security with climate resilience exist. They include a wide spectrum of small, decentralized, bottom-up approaches such as local check dams, other water harvesting techniques, mechanic treadle pumps, drip irrigation, and the system of rice intensification. Combining traditional knowledge and innovative techniques, these approaches rely on the initiatives of small farmers, use water efficiently, cost less than large dams, enhance the food security of the poor, and typically have minimal environmental impacts. Similarly, a diverse mix of decentralized renewable energy projects — including wind, small hydro, solar and geothermal — will not only strengthen resilience to climate change. It will also be effective at improving energy access for the rural poor and limiting environmental impacts. Bottom-up solutions have an impressive track record. Small check-dams have revived several rivers and brought prosperity to arid regions in Western India. Simple treadle pumps have lifted millions of farmers out of poverty. The methods of rice intensification, which increase yields and strengthen climate resilience with improved soil biology but reduced inputs of water, fertilizer and pesticides, have been validated in 42 countries. Yet these approaches have so far only received a minuscule proportion of the aid, investment and incentives that benefit big dams. While there is no single silver bullet, proper legal, scientific and financial support could scale up effective bottom-up approaches in the water and energy sectors immensely. Local communities and small farmers deserve legal rights to the land and water that they have relied on for generations. Small farms and rain-fed agriculture deserve research institutes on par with the facilities that were devoted to the green revolution. Decentralized renewable energy options deserve priority if our aid funds are supposed to reduce energy poverty in a sustainable manner. The Bonn conference should give these approaches the credit they deserve, and call for a massive shift of incentives, aid and investment flows from the centralized ways of the past to the resilient approaches of the future.For more information, please contact the author at {peter@internationalrivers.org}
