It is estimated that 844 million people lack access to a clean drinking water service, 2 billion people drink water from a contaminated water source. Each year this leads to an estimated death rate of 502.000 people. Producing clean water is a very intense process that requires a considerable amount of energy and efficient technology to run the water purification process.
When I was young, like most children in developing countries, never had a chance or dreamed of using a microscope in primary school, even in high school microscope usage was rare yet I was studying science. This is a major challenge for the scientific schools students and lowers the science knowledge transfer. This challenge is not just because the governments are not doing anything but to have enough scientific infrastructure is very expensive. It has an impressive magnification lens up to 140x and weighs just 8 grams.
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 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.
Zipline, a robotics company based in California, recently launched the use of medical drones to transport bloods to remote hospitals in the Western province of Rwanda, that have challenges with lack of proper infrastructure and quick access to medical supplies. The launch at Kabgayi hospital, in the Southern Province of Rwanda was in the presence of HE Paul Kagame, the President of Rwanda.
Africa will need bold measures in order to avert a looming health and environmental crisis - which is the result of air pollution according to a recent OECD report. The report also shows that outdoor and indoor pollution in Africa are causing more death and carry more estimated costs than unsafe water and sanitation and childhood malnutrition. The report says that most of this pollution comes from energy generation, open fires in household operations and imported used equipment.
The 2016-2017 edition of the Global LEAP Competition kicked off September 2016, and nominations for this wave’s world’s most innovative off-grid cooling technologies are open till January 2017. The competition which attracts entries from all over the world, and which seeks to award three most-innovative off-grid refrigerator concepts, with a total prize pool of $600,000.
Right this minute; a woman somewhere in rural sub-Saharan Africa is on a long trek. Not because she’s part of a nomadic tribe or visiting a neighbouring village but because she has to do something that many of us with modern conveniences take for granted – cook for her family. This woman represents the reality of about 3 billion of the world’s population who cook meals over an open fire everyday. People who just need an easier way to get things done. Showcased in the Network’s Solutions Database along with other low-tech projects, the Ezy stove does just that.
Living off the grid, without access to stable electricity, carries consequences beyond simply not being able to switch on the lights at night. In hospitals and clinics across developing regions, the inability to rely on electricity — or a complete lack thereof — translates into profound shortcomings in the provision of life-saving treatments. William Steel interviewed Julia Römer for Cleanleap, Julia co-founded Coolar in 2014, with the goal to develop a better solution for off-grid refrigeration of medical supplies.
That UAVs can fly brings immediate advantages in terms of how they may travel, and the locations they can reach — often surpassing what’s possible with conventional means of transport. Meanwhile, refinements in computer systems has led to advanced navigation and control systems being embedded within UAV systems — a development that’s been crucial in enabling UAV services to function effectively. With improvements in performance, even consumer grade UAVs are able to carry and deliver small packages over considerable distances.
