Africa Must Feed Itself

by Dr. Akin Adesina, Dr. Wangari Maathai and Dr. Graça Machel

Africa is rising. The 2010 Ibrahim Index of African Governance reveals some very good news: 40 out of 53 African countries have made significant strides in terms of economic and human development indicators. The Millennium Development Goals Report of the United Nations show that the agricultural growth rate has become positive, a first in almost thirty years. Between 1990 and 2005, the proportion of people living on less than $1.25 per day declined from 58% to 51%. The proportion of undernourished people declined from 31% in 1990 to 26% by 2005-2007. The African Development Bank has published an upbeat African Economic Outlook that points to a bright future for the continent.

Yes, our continent is scoring some major victories, but we are far from winning the war against hunger and poverty. Africa still has 300 million people living on less than $1.25 per day – nearly as many people as are living in the entire United States of America. The vast majority are smallholder farmers, about 70% of whom are women.

Africa’s average staple crop yield is still less than one ton per hectare, compared to a global average of 5 tons per hectare. For millions of farmers in Africa, accessing basic technologies to help them raise food production is a major challenge. Leaders have failed to urgently prioritize the challenges facing poor farmers in Africa. Leaders must act on their behalf.

Farmers should be able to at least feed their country’s population. In the USA, farmers represent only 1 % of the population, but they still feed the nation and generate enough surpluses to feed many more people around the world. Yet, in Africa, we see such shocking sights of farmers queuing for food aid. What a paradox! The 70% of our population working in agriculture cannot feed themselves, let alone the 30% that are not in agriculture. Many African countries still rely on food aid and the continent as a whole spends $25 billion every year importing food.

No politician hoping to become President in America dares ignore the American heartland. President Obama kicked off his historic election in Iowa, the breadbasket of America. But in Africa, the political cost of inaction on hunger and poverty has been zero. Our politicians count on constituents in rural areas who engage in farming for a living to keep them in office, yet they largely ignore agriculture.

But change is coming. What matters for millions of Africans is the ‘democracy of the stomach’. The food crisis and social unrest that the continent witnessed during 2007-2008, rekindled by the recent food riots in Mozambique in 2010, are tipping points. Political pressure is building as empty stomachs rumble. A growing number of countries are responding. For example, Mali is now spending 11% of its total budget on agriculture, Burkina Faso 15% and Ethiopia 17%.
But deeper changes are needed. Agriculture in Africa has for far too long been managed as a development program. Agriculture is a business and should be seen and supported as such. With 70% of our people engaged in the sector, African agriculture is a potentially very powerful engine of growth that must be kick-started to generate greater domestic income, savings and investment.
As the globe marks World Food Day, we need to ensure the right to food of every African. Begging for food is not the way to ensure that right. The right to food is only truly meaningful when a nation can feed itself.

Local solutions are working in Africa. Malawi, for example, is now self sufficient in food production, five years after it faced a major food crisis. It achieved this by significantly increasing government support for its farmers. Access to improved seed and fertilizer and the knowledge to use them turned the tide. Malawi fed its 15 million people. It also exported 400,000 tons of maize in 2009.

On the rolling hills of Rwanda an agricultural revolution has begun. The plan is bold and the payoffs substantial. Government support to farmers was provided to help them afford needed farm inputs. The result was an agricultural growth rate of 15% in 2009 and national food security.

What has brought about these emerging agricultural revolutions? The answer is simple: political will and government support for farmers. When leaders do their part, African farmers will stand and deliver.

African farmers are no different from farmers in other parts of the world. Our farmers, the majority of whom are women, are hard working and entrepreneurial. What they need are comprehensive farm support policies that will allow them to produce more food to feed the continent.

An African green revolution – one based on political will and country driven solutions – will help Africa feed itself by raising agricultural productivity in sustainable ways. When we are able to feed ourselves, our freedom will be meaningful. Only then will democracy and the right to food be truly meaningful for the 300 million of our people still living in extreme poverty.

Dr. Akin Adesina, Vice President of the Alliance for a Green Revolution in Africa, Dr. Wangari Maathai, Nobel Peace Prize Winner and environmental and political activist, and Dr. Graça Machel, former first lady of South Africa and Mozambique and a member of the Group of Elders, were recently appointed by the United Nations Secretary-General to the Millennium Development Goals Advocacy Group.

African Fossils Suggest Complex Life Arose Early

By Gwyneth Dickey (Science News)
Researchers have found what may be the earliest evidence of multicellular life on Earth. Large fossils uncovered in 2.1 billion-year-old rock from Gabon, in western Africa, appear to be incipient examples of macroscopic life in what was then a sea of single-celled microbes.
A three dimensional X-ray image of the outer (left) and inner (right) body of a fossil from the Gabonese site. Scientists believe that multicellular life really took off much later, in the great expansion of animal body plans known as the Cambrian explosion 545 million years ago.
“The discovery is fantastic because it shows the existence of multicellular fauna 1.5 billion years earlier than what we know,” says team leader Abderrazak El Albani, a sedimentologist and paleobiologist at the University of Poitiers in France. “This is important to understand the evolution of life on Earth.”
Some researchers have suggested multicellular organisms arose as early as 1.6 billion years ago, but the evidence is controversial. El Albani and his colleagues were thus surprised to find large fossils in the newly excavated ancient Gabonese rocks. So far, the team has collected over 250 specimens that range in size from 1 to 12 centimeters.
Using detailed X-ray imaging called microtomography, the team created three-dimensional images of the fossils inside and out. The organisms had flat, round, soft bodies, with slits around the edges and complex, patterned folds inside. The creatures belong to new species that have never been described, the team reports in the July 1 Nature.
Other researchers agree that the large size, thickness, and three-dimensionality of the organisms suggest that they were, indeed, multicellular. “There does seem to be something more than just a clonal colony of bacteria,” says paleobiologist Philip Donoghue of the University of Bristol in the United Kingdom.
El Albani and his team believe the complex patterns and folding mean that cells must have coordinated their growth through chemical signaling, like all multicellular organisms do. The fossils could even be the first examples of eukaryotes, cells with membrane-bound nuclei, according to the team.
But since actual cells were long gone from the sediments, the team had to prove these fossils were not simply mineral formations that looked like animals.
Pyrite, a sulfur-containing mineral also known as fool’s gold, filled the fossils, providing evidence that sulfate-breathing bacteria had eaten away at living tissue. Carbon and sulfur isotopes also confirmed the fossils’ organic origins.
Further analysis showed that the fossils couldn’t have been more recent organisms that burrowed deep into sediments, because the surrounding rock was the same inside and outside the organisms’ folds.
Rock chemistry indicates the organisms lived about 30 to 40 meters deep in sea water. They likely breathed oxygen, which by that time had been building up in the oceans and atmosphere for 350 million years. Donoghue says it’s exciting that scientists are “edging back” the fossil record toward this so-called “great oxidation event” 2.5 billion years ago.
The research team plans to do more experiments to determine how these organisms lived and how to further categorize them

Green Revolution Gathers Steam in Kenya

The pressure on the environment from cooking is being blamed for a range of problems, from deforestation to creating gases contributing to global warming. And then there is people’s health: many die in the developing world from the fumes of indoor cooking. Entrepreneurs, engineers and scientists have launched many initiatives around the world to develop fuel-efficient and cleaner burning stoves. But they all share the same challenge: how can they meet local needs and tastes and keep the price of a stove affordable? Here is one example from Kenya of a successful stove and oven business that has become a regional success story.
A Kenyan entrepreneur has cooked up a fuel-efficient stove and oven that uses less of a precious national resource: wood from trees.
Renewable energy solution in Kenya
Most African households using fuel-burning stoves either cannot afford clean-burning fuels like natural gas or electric stoves, or do not have access to them. They are stuck having to burn wood or other materials like animal dung – collectively called biomass – on open fires.
As well as using up wood and contributing to deforestation, there is another downside to these stoves. The use of polluting fuel-burning stoves by half the world’s population – including 80 percent of rural households – is a documented contributor to a host of health problems. Poor households not only have to contend with the ill health effects of dirty water and poor sanitation, the fumes from burning dung, wood, coal or crop leftovers lead to the global deaths of more than 1.6 million people a year from breathing toxic indoor air (WHO).
Two solutions in Kenya are helping people to cook more efficiently (meaning less time wasted on gathering material to burn, and less fuel used) and reducing cooking time by using heat more effectively.
Invented by Dr Maxwell Kinyanjui, the Kinyanjui Jiko is a fuel-efficient charcoal oven that comes in small, medium and large industrial sizes. Made entirely in Kenya, the ovens are custom designed for a variety of environments, from domestic household use and on-the-go safari models to high-capacity models for micro-enterprises and large institutions. Cooks can use the ovens to bake, toast, steam or boil. And they are 40 percent cheaper than cooking with electricity and between 15 and 20 percent cheaper than gas.
Kinyanjui’s Musaki Enterprises Ltd.(www.reskqu.blogspot.com/2009/01/arboretum-project.html) has developed a reputation for pioneering work in developing fuel-efficient stoves and ovens. Its most popular success to date has been the Kenya Ceramic Jiko (jiko is Swahili for cooker), or KCJ, a cheap, simple and effective stove. The company was set up in 1992, but has been involved in international aid-funded research and development efforts since the 1980s.
“My dad was on a very good team of highly motivated individuals in the early 80s who developed the stove through pragmatism, logic and good old-fashioned ingenuity,” said his son, Teddy Kinyanjui. “He then set up the independent Musaki Enterprises.”
The KCJ uses a ceramic liner placed inside a metal container. The metal is usually recycled, often taken from 55 gallon steel drums. The ceramic liner stops the heat energy from simply escaping into the environment and helps to focus the heat on cooking. Simply adding the ceramic liner reduces the stove’s fuel consumption by between 25 and 40 percent. The charcoal or wood sits in the ceramic basin and the burnt ash falls through holes in the bottom of the liner.
The stove design was a result of international and Kenyan cooperation, and has become popular in many African countries, including Uganda, Rwanda, Ethiopia, Malawi, Niger, Senegal and Sudan. It is used in 50 percent of urban homes in Kenya and 16 percent of rural homes.
Musaki Enterprises say the KCJ stoves on average save between 1 and 1.5 tons of CO2 per stove per year compared to other models. In supermarkets, the KCJs retail for around US $5 and the Kinyanjui Jiko ovens start at around US $100.
The deployment of the KCJ stoves has helped in slowing the deforestation of the country, but has not been able to bring it to a halt because of population growth and poor re-forestation efforts, says Teddy Kinyanjui.
“The lack of forward planning in tree planting is making firewood and charcoal harder and harder to obtain,” he said. “Fossil fuels are unavailable or unaffordable. Tree planting must begin now on a huge scale for people to continue cooking.”
Teddy won’t reveal how profitable the KCJ stoves have been, but says, “I wouldn’t have gone to school if they didn’t sell well.”
“Well, more and more people keep buying the damn things as fast as we can make them, so I think our customers like them,” he said. “They really all seem to like that the stoves cook really well for really cheap and are very high quality.”

New scientific finding on mosquitoes is not good news on the malaria front

Mosquito sp. Anopheles gambiae is responsible for malaria

The research team of researchers from the University Of Notre Dame, the J.C. Venter Institute, Washington University and the Broad Institute are reporting that two strains of mosquitoes responsible for malaria in Africa are evolving at an unexpected rate into genetically distinct species. This is not good news as it will further complicate the tedious fight against malaria by creating a situation where strategies and medicines developed against malaria may not be effective against both strains

The studies were reported in the magazine Science. The two issues (Science 22 October 2010:Vol. 330. no. 6003, pp. 512 – 514; Science 4 October 2002:Vol. 298. no. 5591, pp. 115 – 117) suggest that the evolution process is occurring faster than previously thought, and point to already substantial differences in the two strains. The two species already able to exploit different habitats.

Malaria kills one child every 30 seconds worldwide, according to World Health Organization. The incidence could be higher in sub-Saharan African.

The work focused on the Anopheles gambiae, the mosquito that is the most transmitter of malaria in sub-Saharan Africa. The study describes the two strains as “M” and “S” strains of the “Anopheles gambiae mosquito

What they found was that the mosquitoes are diverging into two different incipient species, which are called M and S forms. Physically, the two forms are cannot be distinguished, they are and able to interbreed, but their DNAs are diverging into different directions. Their behaviors are different under different conditions.

The ‘M’ form is usually found in around permanent bodies of water and spends most of its life in water environment. This means that it can thrive in dry areas that are normally not good habitats for malaria transmitting mosquitoes.

The S form is used to small, short-lived water bodies and breeds well during the rainy season. It is clear how these ‘tricks’ by the mosquito could undermine current efforts to combat the disease.

Work is ongoing to sequence the genome of the two forms of mosquitoes which could help us to decipher why they are different and how to devise ways to combat them more effectively.

Bothered by pain? Consider a trip to Zambia, say John Hopkins researchers

Lake Victoria, Zambia, Africa
Lake Victoria, Zambia, Africa

Researchers from Johns Hopkins University in Baltimore, U.S, have reported on a new study that will surely gladden the heart of the Zambian Ministry of Tourism. The conclusion of the study? Simply gazing at the amazing images of Victoria Falls on the Zambia-Zimbabwe border is enough to reduce the feeling of pain for many patients such as those on cancer treatment. Specifically, 120 people who are outpatients undergoing bone marrow aspiration and biopsy (BMAB) were evaluated.
BMAB is an unwanted long and painful procedure involving a large needle which is inserted into the back of the pelvic bone and bone marrow is drawn out, all using only local anesthesia. 44 patients were assigned a beautiful nature scene with accompanying calming sounds, 39 were assigned a typical city scene with city sounds and 37 were assigned standard care.
On a scale of 0 to 10, with 10 being the most painful and zero being minimum or no pain (known as the John Hopkins Instrument), patients were asked to rate their pain.
The Results
The control group, which had neither nature nor city scenes – on average marked BMAB as 5.7
While those patients exposed to the scenic nature images and calming sounds recorded an average of 3.9 on the pain scale, a very statistically significant reduction.
Patients exposed to the city scene and sound found the treatment just as painful as the control group.
The report concludes then that viewing a nature scene while listening to nature sounds is a safe, inexpensive method that may reduce pain during BMAB.

Looking at the Victoria Falls with calm music can help you deal with pain

But before the Zambian tourism industry starts popping out the champagne, it is worth nothing that the researchers say the patients do not need to leave their sick bed. Just exposing the patients to the pictures and sounds while on their sick bed is good enough as breaking your wallet to visit the Victoria.

A Breakthrough in Malaria Research

Scientists from Scotland have reported a major breakthrough  in fight against malaria.

The team from Edinburgh University in collaboration with  a team in Portugal  have discovered a gene that offers the drug resistance trait to the parasite. Drug-resistant plasmodium falciparum parasites are a major hindrance in the battle against the deadly disease. Chloroquine, the most commonly prescribed medicine against malaria has lost its effectiveness due to the proliferation of chloroquine resistant parasites.

Scientists think this is a  major development in malaria research. Malarial kills one to three million people annually, mostly children. These findings may pave a way for a new class of anti-malarials.

The study has been published in Biomedical Central (Sept 2010)
