Food demand is projected to significantly increase anywhere between 59% to 98% by 2050. Sustainable food growth is essential for humanity’s health and survival, and the need to increase global food supplies is an urgent one. While food security is a complex issue, vast improvements can be made by being smart with our resources and working to keep the energy used in food production to a minimum.
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.
Sri Lanka is one of the South East Asian countries that was devastated by civil war in the past years. On a postive note it ranks as the 4th country in the world for its large number of elephants. These beautiful animals are threatened by human activities such as ivory trading to generate income.
Climate change adaptation costs in developing countries could rise as high as US$250-500 billion per year by 2050 according to UNEP. With the world grappling with climate change, we need sustainable solutions to save our precious planet. Air pollution, deforestation and contaminated waterways are major issues, and there is a lot of work to be done in these sectors.
It has been over six months now since the ban on plastic bags was implemented in Kenya. Officials looked to target sellers and manufacturers head on, outlawing selling, using and producing plastic bags completely
The World Banks Lighting Global Program, Dalberg Advisors and GOGLA (Global Off Grid Lighting Association) have launched number four of its bi-annual publication – an in-depth analysis of the trends of the global off grid solar power market. The report examines an expanding market that is helping developing countries make a 'cleanleap' from fossil fuel based electricity to using renewable energy from the sun.
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.
