From Albania to Zambia, people across the globe love gardening. For some, it is a way to wind down and to enjoy some spare time, while for others, it is the difference between having food on the table and going hungry. Gardening is even popular within teeming cities like Nairobi, where residents have come up with novel solutions to squeeze gardens in to the most unlikely urban locations. Let’s find out what is involved.
Food, shelter and clothing are basic needs for the humankind; but, without an adequate standard of living, these core principles are hard to achieve. With less than ten percent of Africans living in decent housing in urban areas, the need for affordable, sustainable technology for housing has never been greater. Most African governments have backed the concept of prefabricated housing and realize that it is an ideal solution to close the gap of housing problems in their countries
The World Bank's Main Grid Connectivity-Mapping Tool is a an approach that can be used ot clearly understand electricty capabilities in an area at a granalar level. As companies take a cleanleap to being powered by solar, it is a way of routing their solar energy inventory to spaces where there is low connectivity.
The World Health Organization (WHO) estimates that around 150,000 annual deaths in low-income countries are brought about by the adverse effects of climate change. It’s time to open our eyes and realize that overall health concerns are greatly affected by the world around us and it’s time for serious positive action.
In Nigeria a young green energy innovator has developed an electric mini-grid powered by biogas made from organic waste, and the power it’s generating, is benefitting 550 people of Rije village in Abuja. Dubbed Waste2Watt, this first of its kind renewable energy project in the country, is generating 20 kilowatts of power, after converting agricultural and communal organic waste into electricity, by use of a biogas digester. The electric power generated is then distributed via a mini-grid to the villagers.
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.
