Last month, South African Airways and Boeing celebrated flying the first-ever plane in Africa to be fuelled by biofuel from tobacacco. ProjectSolaris aims to produce local cleaner biofuel to power planes in South Africa, whilst providing local jobs. It means the aviation industry is also set and able to use biofuels, a measure that will help lower carbon-emissions. The South African Airways project will also produce biodiesel for cars and for other industries.
According to projections from the United Nations, Earth's human population is on track to reach eleven billion people by 2050; and in case this seems like a a far distant future, keep in mind that as of 2017 this is a mere 33 years away–a single generation. How will the Earth feed all of these people? Vat-grown burgers!
Around the world, arable land or land that is suitable for agriculture is dwindling. The rural-to-urban migration and growing cities of the world have constricted the capacity of the rural populations to provide food, for both urban and rural populations. At the same time, our overall world population is increasing. How do we feed an additional 2 billion people by 2050? In Kenya, a US-based not-for-profit social enterprise called CAN YA LOVE (pronounced as Kenya Love), is working with a consortium of local partners, to erect pillar gardens in urban areas such as slums, community land spaces and in schools.
The International Renewable Energy Agency (IRENA) is an intergovernmental organization that helps countries move to more sustainable energy options. The Agency also provides a focal point for governments from around the world to work together and share information on clean tech best practice. IRENA recently released a policy brief Solar Pumping for Irrigation: Improving livelihoods and sustainability, this brief forms part of a broader agenda focused on renewable energy opportunities in the agriculture and water sector.
Another innovation with regard to solar energy category was that of solar roofing tiles presented by Strauss Energy. Strauss is into the business of incorporating solar cells - called Building Integrated Photovoltaic (BIPV) into building materials such as tiles. The solar tile is either made of a plastic material or mixture of plastic and ceramic components, with solar cells being overlayed on top. This model seeks to combine both the advantages of house roofing and power generation. The solar cells work in the normal way by converting sun’s energy into power which is then channeled to power devices at home, office or factory.
In Kenya 17.3 million people lack access to clean water with water borne diseases like diarrhea and Cholera being the leading cause of death for children under five years. But a group of women have found a low cost method of purifying water, which is now backed by science - embracing seeds from the wonder tree Moringa oleifera.
In late 2004, Kisumu bay, Lake Victoria, was covered in a blue-green hue. The algal bloom - a proliferation of cyanobacteria – demarcated an area of low oxygen and eventually decomposing algae, causing fish to suffocate or flee and contaminating the drinking water- a dead zone. Adapt-N, a software programme developed by researchers at Cornell University seeks to solve this problem.
