Do large dams still fit in the sub-Sahara energy and water agenda?

Huge dams have been touted as effective in providing drinking and irrigation water, all cheaply and sustainably. Recent studies reveal otherwise as most of these projects in sub-Sahara turn out to be more costly than planned. A recent study has quantified claims that large dams also lead to more malaria being spread in the sub-Saharan, thus adding more weight to concerns on whether these projects should be pursued actively in favor of the alternatives.

Turning Poop Into Power

Long Sokhon is a small-scale farmer in Cambodia’s Pursat Province. Like 85% of Cambodians, she makes a modest living off the land. She used to cook for her family of eight over a wood-chip fire by night. Sokhon lived the way most do in rural Cambodia—one of the poorest countries in South East Asia with a population of 15.8 million. Then, she was given the opportunity to have a 2,000 litre slate-grey tank installed in the vegetable patch. Long Sokhon was chosen as part of a biodigester pilot project run by Engineers Without Borders Australia and Live & Learn Environmental Education

Tanzanian innovator rises to solve water sanitation problems

A local entreprenuer in Tanzania has devised a solution that seeks to eliminate all the problems associated with unsafe/unclean water and sanitation. It will help locals avoid related diseases. What's more is that his solution is low-cost and requires no power compared to other water treatment technologies. It is also made from local materials, recyclable, and versatile in that it can be tailored to treat water in vartually any location/area. The nano-filter combines nano-filtration technologies with sand-based water filtration techniques. It has already been rolled out in the market and is gaining ground.
