The efficiency of waste management is an important aspect of sustainablity - especially with the global amount of waste expected to dramatically increase over the coming decades. Mobile technology from IBM is being used for mapping and tracking waste collection, as well as reporting related data in real-time, in order to enhance related decision-making.
It is a towering mountain of waste, a 50-year-old dumpsite, in the outskirts of Addis Ababa, locally known as Koshe, an Amharic word meaning “dirty”. However, this heap of waste will be a thing of the past with the construction of its first ever waste to energy plan.
The construction of the Grand Ethiopian Renaissance Dam (GERD) resonates of nothing but patriotism and deep commitment of Ethiopians towards achieving clean energy for their country. Since the inception of the dam in 2010, there have been a number of issues but the project is now moving ahead at full steam.
Adoption of biomass power generation technologies in Africa has been challenged by a variety of factors including high capital costs and lack of feedstock. However, with biomass contributing to only 5% of power production in the continent, these projects hold a promise to helping boost the much needed power in developing world. It is not only the largest biomass power plant in Africa, but Gorge Farm AD Plant in Kenya will be Africa's first anaerobic digester.
According to the African Development Bank (AFDB), more than 30 million Africans (about 3% of Africa’s total population) are living outside their home countries. This figure includes those living within other African countries. These African migrants send money to their families in Africa. Remittances by African migrants play an important role as a source of financing and foreign exchange for African households and countries. For Africa as a whole, remittance inflows have more than quadrupled since 1990, reached US $40 billion in 2011. This represents about 3% of Africa’s total GDP. Globally, the amount of remittances reached US $300 billion in 2010, surpassing foreign direct investments (FDI) and official development assistance (ODA) combined.
We all like to do our bit for the environment. We recycle, use kitchen waste to make compost, use reusable shopping bags, etc. These are all done in an attempt to decrease the usage of our planet’s resources and to reduce pollution. However, there might be more than you can do without even setting foot out of your home. When it comes to energy consumption, temperature regulation is one of the highest costs. We heat our homes in winter and cool them in summer.
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.
