Water is one of the great human challenges of our time. As an essential resource for human life, it is staggering that so much of the world should exist without the basic potable water and sanitation services that we know in the developed world. Making a Cleanleap in urban water management practices could facilitate greater access to water for millions of existing city dwellers in developing countries.
The Institution of Mechanical Engineers (IMechE) have released a report A tank of cold: cleantech leapfrog to a more food secure world. The key message from the report is that about a quarter of food wastage in developing countries could be eliminated with better refrigeration equipment. The report describes a new way of creating a cold chain system in emerging economies. This system can be built from the ground up as there is little existing instrastruce and the ability to harness renewable energy. Creating the opportunity to cleanleap over existing more polluting systems.
Small steps can be much larger than they seem, some steps forward become great leaps. Ethiopia, a vibrantly growing economy attracting many investors, will need alternative sources of energy to sustain production and economic growth. It is out of these challenges the country is looking for more clean and renewable energy alternatives.
Although the energy industry is still working to make CCS effective using large mechanical and chemical solutions, there may be a better answer coming from nano-technology. Lawrence Livermore Laboratories are working on a new solution that uses tiny permeable nano-beads filled with a solution of sodium bicarbonate (NaHCO3).
WWF International recently launched a report Crossing the Divide: How to Close the Emissions Abyss to coincide with discussions by UN climate negotiators, focusing on emissions reductions in the pre-2020 period. The report highlights the ‘gigatonne gap’ of emissions reductions needed to meet 2020 commitments. In the report, national contacts in various developed and developing countries provide an analysis of the current situation on energy and climate change, and then provide ways their governments could do more to close the emissions gap
Three young innovators in Kenya have developed an award winning technology that harvests clean drinking water from the air, targeted at rural communities living in dry regions, and communities in urban areas lacking access to clean water. The innovation dubbed Majik Water is powered by solar energy and utilizes sponge like non toxic desiccant materials to generate water from the air.
One of the most exciting ventures a country and its cities can undergo is that of modernizing and redeveloping its buildings. The progress made is almost always positive, and literally can give cities a new face. Major infrastructure projects in Vietnam are not so slowly transforming the city for the better, upgrading various aspects ranging from transportation to water treatment and infrastructure.
In Northern Upper East Ghana, a water conservation technology is enabling about 400 smallholder farmers from 10 communities to farm in dry seasons. As a result they are now getting at least two crop seasons annually as opposed to one, after implementing the PAVE irrigation Technology which harvests flood and rain water, and stores it in underground aquifers where it lasts for up to 180 days.
In Rwanda, a ‘Pico-hydro’ refers to a power system with a capacity less than 50kW. Their advantage over other power systems is their cost-effectiveness and simplicity, and come in different designs, planning and installation processes. It is an economical source of power that has proven useful in delivering clean energy to some of the world’s poorest and most remote places.
Whether they are consumed as grains or flour they are always products in high demand in Africa - these being cereals such maize, sorghum, millet and wheat. One of the issues with these widely consumed crops is when people want to grind them and consume them as flour, with most remote areas lacking access to electricity and therefore use expensive fossil fuel to run milling machines.
Better housing is one of the key indicators of the economic development, but most developing countries still have a challenge to secure clean homes for their habitants. Dirt floors are often responsible up to 80 percent of diseases. In most cases, parasites live in soil in form of feces and bacteria that can be contagious by either absorption or a simple contact. EarthEnable has introduced a solution to all those problems.
The Croton tree, which is commonly known as Mukinduri in Eastern and Central part of Kenya, is now a good known source of biofuels and that is being practiced. It grows in a challenging environment and unlike jatropha and palm, it won't bring food and fuel competition. It has no chemical additives and burns cleaner than traditional diesel fuel, with no sulfuric content. It can save our environment from carbon emissions and help in better land usage.
Many companies use traditional methods to measure the impact of solar power investments such as quoting the many dollars invested, number of people using their kits and areas covered by their product, which are inadequate tools for measuring social impact for solar power investments if we have to get it right. Traditional approaches of gathering data are not only expensive, take time to give results and complicated to use, but are also not helpful in terms of boosting solar power funding. The lean data approach proposed by Acumen could, not only bridge solar power funding gaps in developing worlds, but will also help companies to understand emerging markets.
Research undertaken by Greentech Media (GTM) predicts that over the next five years, the global solar market will demonstrate a cumulative average growth rate of around 8%, with emerging economies including India and Latin America leading the progress.
