5 Ways Africa Can Build a New Climate Economy

first_imgBy 2050, sub-Saharan Africa’s cities will increase by almost 800 million people, nearly half of the projected rise in urban population globally. Urbanization in sub-Saharan Africa has been something of a missed opportunity so far, as it hasn’t been accompanied by economic transformation. Many cities already suffer from severe traffic congestion, long travel times, high road fatality rates, low energy efficiency, rising outdoor air pollution and rising GHG emissions. While urban populations are growing rapidly, in many cases, cities’ physical footprints are growing even faster, creating urban sprawl. Kampala, for instance, grew geographically by more than 10 percent a year from 1990-2000, while population grew by 4.3%. A shift towards more compact, connected and coordinated cities will assist in creating a more productive, inclusive and clean urbanization.5. Foster a modern energy transitionEconomic transformation in sub-Saharan Africa will require a large increase in energy supply. At present electricity consumption per capita is 17 of the world average, not enough to continuously power a 50-watt light bulb. Some 620 million people lack access to electricity. Sub-Saharan Africa has a few good things going for it on energy, though. For one, it has an enormously rich portfolio of clean energy assets: about 1,100 gigawatts (GW) of solar capacity, 350 GW of hydro, and 109 GW of wind. In addition, global technological progress has created the potential for developing countries to leapfrog to much more energy efficient processes and products than were available to other countries as they developed decades ago.To read Africa’s New Climate Economy, click here. Low crop yields and rapid population growth have pushed the expansion of cropland in sub-Saharan Africa far beyond the global rate, since more farmland is needed to grow more food for more people. This contributes to deforestation, exacerbates vulnerability to climate change and puts pressure on the fragile ecology in the region’s vast drylands. Intensifying agriculture to boost yields, combined with climate-smart farming techniques, can help boost farmers’ incomes, reduce environmental degradation and strengthen resilience to climate change. Landscape management efforts in Niger have allowed farmers to produce 100 kg/ha (90 lbs/acre) more grain than before, with gross real annual incomes increasing $1,000 per household for more than a million households. These approaches should be mainstreamed into national agriculture plans.3. Diversify into manufacturing and other high-productivity sectorsSub-Saharan countries have the potential to make robust gains in manufacturing and other modern sectors. Africa’s share of world manufactured export markets is so tiny – less than 1 percent – that even a modest increase could have a big impact on the sector’s growth. To build up manufacturing, there is an urgent need to strengthen infrastructure, in particular for electricity. Focused efforts are needed to promote manufactured and tradable service exports through better logistics, special economic zones and other initiatives. Selective industrial promotion policies can help overcome market failures, as long as they’re accompanied by transparency and accountability.4. Unleash the power of urbanizationWomen in Accra, Ghana, where urban density actually declined from 2000-2010.

At the same time, it is expected to be the region worst affected by climate change, with potentially devastating crop losses of up to 30 percent by mid-century.The good news is that sub-Saharan Africa can transform its economy to improve productivity, reduce poverty and reduce the risk of climate change at once.Regional economic transformation weds growth and climate actionIn the first decade and a half of this century, sub-Saharan Africa has experienced a “growth miracle”, with annual economic growth of almost 5 percent putting an important dent in poverty. But sharp declines in oil and commodity prices in the past two years have reduced its projected growth to 1.6 percent in 2016. Despite progress, nearly 400 million people remain in extreme poverty.To build a modern, inclusive economy, policymakers in sub-Saharan Africa have begun to focus on economic transformation, moving workers from low-productivity sectors like agriculture to higher-productivity areas like industry and the service sector, as well as increasing productivity growth within sectors. This is the typical path that advanced economies have taken in the past.The New Climate Economy project has demonstrated on the global scale that climate action and economic growth can go hand in hand. Now it takes those lessons to the African context in a comprehensive look at its potential for green growth. Good policies that recognize the close links between economic, social and environmental priorities can unlock major benefits over the long run.A new report, Africa’s New Climate Economy: Economic Transformation and Social and Environmental Change, lays out five action areas for governments to consider as they form their development strategies for the next few decades.1. Get the fundamentals rightA few basics can help underpin an inclusive and sustainable economic transformation. These include macroeconomic stability, access to finance and better management of sub-Saharan Africa’s abundant natural resources  Greater voice and accountability are essential to ensure government responds to people’s needs, in the fight against corruption and  for more effective management of public budgets. On the social side, the fundamentals include social and human development policies, with an emphasis on public health, education and gender equality.2. Transform agriculture and land useHarvest in Ethiopia.

NASA is launching an asteroidsampling space probe today

first_imgThe next phase in NASA’s exploration of asteroids begins today with the launch of the OSIRIS-REx mission. This probe will travel millions of miles through space to reach an asteroid called Bennu, at which time it will take a sample of the asteroid and return it to Earth. You can watch this mission kick off live later today (September 8th).The asteroid Bennu (technically called 101955 Bennu) is not particularly remarkable on its own — it’s a carbonaceous asteroid (the most common type) that is almost 500 meters (a third of a mile) in diameter. The only remarkable thing is that its orbit takes it very close to Earth. In fact, its orbit crosses Earth’s, and there’s a small chance (roughly 1 in 2,700) that it could hit us in the 22nd century. Its close proximity makes it a good target for the OSIRIS-REx mission.The launch is currently scheduled for 7:05 PM Eastern, but the NASA coverage will go live at 4:30 PM on the NASA TV stream. The OSIRIS-REx probe will be launched on an Atlas-V rocket operated by ULA. The trip to rendezvous with Bennu will take several years, at which time the spacecraft will begin a comprehensive 505-day surface mapping mission. This will help NASA choose a location for the next step.The ultimate goal of this launch is to get a sample of an asteroid back to Earth that hasn’t been scorched by falling through the atmosphere in the normal way. OSIRIS-REx will descend to within 5 meters of the asteroid and extend a sampling arm that is designed to scoop up as much as 4.4 pounds of regolith from the surface. The sample arm has a built-in 5-second timer that ensures the probe will back away to avoid a collision.The sample should be returned to Earth in 2023, giving scientists a chance to examine unspoiled samples of primordial material from the early solar system. Asteroids like Bennu are believed to contain the same organic molecules that were found on planets like Earth when they formed — the same molecules that eventually gave rise to life. Studying Benuu could give us a glimpse into your own past. It all starts with today’s launch.last_img read more

NIH expands program to crack medical mysteries

Required fields are indicated by an asterisk (*) Harvard Medical School in Boston, which received a $9 million award in January to act as “coordinating center,” will facilitate collaboration between researchers and will make patient data widely available through public repositories such as NIH’s database of Genotypes and Phenotypes, explained Anastasia Wise, director of NHGRI’s Division of Genomic Medicine, at a press conference today.Since the program launched in May 2008, it has received applications from about 3200 patients, 750 of which were selected for study. “There has never been a shortage of referrals to the program,” UDP Director William Gahl said today. (Indeed, in 2011, the program temporarily stopped accepting applications to catch up on the flood of inquiries.) The program’s track record for medical sleuthing depends on how you define a diagnosis, Gahl said. Between 25% and 50% of cases are considered “resolved” based on a clinical, molecular, or biochemical diagnosis, while about a quarter are closed without an answer. “You can see that this is a difficult work, in which we sometimes fail,” he added.The program now admits about 150 patients per year at the NIH Clinical Center, but plans to accommodate 50 per year at each of the seven sites by the summer of 2017.

Country An effort at the U.S. National Institutes of Health (NIH) to diagnose mysterious diseases is undergoing a major expansion. Representatives of the Undiagnosed Diseases Program (UDP), administered by NIH’s National Human Genome Research Institute (NHGRI), announced today that six medical centers will join the program, forming a network of clinical sites to investigate intractable cases from patients around the country. The program aims to offer patients a long-awaited diagnosis—and sometimes treatment—while building up data for scientists studying the genetic basis of rare diseases.The new sites—Baylor College of Medicine; the Harvard teaching hospitals (Boston Children’s, Brigham and Women’s, and Massachusetts General); Duke University; Stanford University; the University of California, Los Angeles; and Vanderbilt University Medical Center—will each receive a 4-year grant of roughly $7.2 million to participate. Like the NIH Clinical Center in Bethesda, Maryland, that served as a pilot site, the centers will host patients for about a week at a time, performing extensive clinical tests and genetic sequencing in search of an explanation for their symptoms. read more
