Simple tools help a drying African region cope with climate change
fff
The Sahel region of western Africa is a belt of semi-arid grassland lying between the Sahara to the north and savannas to the south.
It spans about three million square kilometers (1.1 million square miles) and includes the nine countries of Burkina Faso, the Gambia, Chad, Mali, Guinea-Bissau, Mauritania, Senegal, Niger and Sudan.
The region, home to more than 55 million people, is no stranger to natural disasters. Throughout the 20th century, droughts have brought death and famine and left millions dependant on food aid. Periods of heavy rainfall too are a problem, destroying crops and washing away villages.
In addition, the Sahel is also struggling with large-scale land degradation caused by deforestation and overgrazing.
A drier future
While climatologists are divided about the reasons for the harsh weather fluctuations, experts say one thing's clear – the pattern's set to get worse.
"For western Africa, climate researchers can say with a high degree of certainty that all kinds of extreme events – prolonged drought periods, more heavy rainfall – are very likely," Hermann Lotze-Campen, an agricultural economist at the Potsdam Institute of Climate Impact Research said.
"Extreme weather coupled with already high temperatures of above 45 degrees Celsius in Sahel countries are likely to increase water scarcity and water stress and make the region drier."
That's bad news for a region dependent on rain-fed subsistence farming of sorghum, cotton, millet and other dryland yields for its survival.
"Lower rainfall means lower crop yields. Estimates suggest crop yields in the Sahel may go down 20 to 50 percent in the next decades and this at a time when countries such as Niger have the highest population growth rate in the world," Chris Reij, a sustainable land management expert at the Centre for International Cooperation at the VU University Amsterdam said.
Simple solutions
The myriad problems have long attracted international donors and aid efforts to help the region adapt to climate change.
The village of Jataba in the Gambia, for instance, is part of a large 114-million-euro ($157 million) project financed by the European Union to provide the Sahel with solar-powered water pumps.
But some point out that vast funds aren't necessarily what's needed to make a difference.
"What really works are simple irrigation and water storage techniques for subsistence farmers. The moment you bring in a high-tech system, then you have problems of investment as well as of know-how," Dirk Thies, who heads German technical aid group GTZ's agriculture project in Burkina Faso, said.
Experts say there are plenty of successful climate change-adaptation projects in the region ranging from water harvesting techniques to modifications on traditional farming practices.
Relying on local knowledge
Chris Reij, who's worked in the Sahel for more than 30 years, pointed to a project in Burkina Faso that's revived a local tradition of sowing crops in a grid of planting pits known as "zai."
The pits retain water for long periods of time, concentrating rainfall and nutrients onto the roots of crops, thus allowing them to survive dry spells. The method has helped reclaim land that had become semi-desert.
Another initiative started by the GTZ in the late 1980s has helped farmers in Burkina Faso build stone bunds. These are stones piled up in long narrow rows that follow the contours of the land in order to capture rainwater runoff and soil.
The projects, technically called "farmer-managed natural regeneration," are developed with the involvement and inputs of local farmers long used to coping with climatic fluctuations.
"The local farmers are very sensitive to weather changes – they've been dealing with it for thousands of years. They're very aware of the risks and never lay all their eggs in one basket. Frankly, a farmer in Burkina Faso is much better prepared for climate change than a farmer in Germany," Thies said.
Green shoots
Another little-known success story in the Sahel involves a tree-based approach to farming called agro-forestry. A Malian-British NGO called Sahel Eco and others have supported farmers in growing and nurturing native species of trees that sprout naturally amid their cropland.
The trees shade crops from intense heat, buffer the wind and help the soil retain moisture. Their leaves provide fodder for livestock and act as mulch when they drop to the ground, boosting soil fertility.
The practices have spread across swathes of Burkina Faso and neighboring Niger and Mali and are credited with recharging underground water tables in some places by as much as five meters.
"Our studies show that that in Niger and Burkina Faso, about 500,000 hectares of completely useless land have been restored to productivity in the last 20 years thanks to such measures," Reij said, adding that in Niger alone farmers have grown 200 million trees. "It's probably the biggest positive environmental transformation in the Sahel. Nobody could have imagined it."
The green shoots of recovery are also visible in satellite images analyzed by the US Geological Survey and made public in 2008.
"A win-win situation"
An important role played by aid groups involves lobbying governments to make changes to policy such as granting farmers legal ownership of their trees so that the farmers have an incentive to take care of them.
Thies said the GTZ's current focus in Burkina Faso is to break what he calls a "negative cycle of subsistence farming" by urging the government to make investments to create a market for small farmers.
While the Sahel region undoubtedly faces a range of formidable challenges, some say the success of these simple projects offers important lessons for future mitigation policies.
"These projects are a win-win situation: they help farmers adapt to climate change and at the same time help to reduce rural poverty and boost food security," Reij, said. "There are many more success stories under the African sun than is commonly believed."

Simple tools help a drying African region cope with climate change
Global warming is set to make western Africa drier, threatening the region's widespread subsistence farming.

Disasters | 06.10.2010 Hungarian officials fear toxic spill could reach Danube
Disasters | 06.10.2010
Hungarian officials fear toxic spill could reach Danube
Hungary declared a
state of emergency on Tuesday after a toxic sludge spill swamped seven
villages in what officials called the worst chemical accident in the
country's history.
Up to 40 square
kilometers (15.5 square miles) of land have been affected, giving rise
to fears that the sludge could eventually pollute the nearby Danube
River, which courses through three European capitals before flowing into
the Black Sea.
"The sludge could
reach the [Danube] in four or five days," said the deputy chief of the
water management company for western Hungary, Sandor Toth, adding that
"from the point of view of water management, it's a catastrophe."
The two-meter
(6.6-foot) tide of red toxic sludge killed four people and injured 120
others on Tuesday. Eight of the injured are in serious condition and six
people remain missing. Officials said on Wednesday that the death toll
could rise.
The European Union
would be willing to help Hungarian authorities should they need
assistance in cleaning up the toxic chemical spill, EU spokesman Joe
Hennon said Wednesday.
Further down the
Danube in Romania, the country's Environment Ministry said it was
monitoring water quality round-the-clock and stressed that the level of
pollutants had not crossed the acceptable limits.

The area around Ajka,
in western Hungary, was inundated with the sludge after the walls of the
Ajkai Aluminia Refinery's residue reservoir, about 160 kilometers (100
miles) southwest of Budapest, broke on Monday. The plant produces
alumina, which is used in the smelting of aluminum.
The red mud is a toxic
residue left over from the plant's aluminum production. It is slightly
radioactive, highly corrosive and contains toxic heavy metals such as
lead, cadmium, arsenic and chromium. It destroyed all vegetation other
than trees and seeped into hundreds of houses in seven villages, leaving
residents unsure of when they would be able to return to their homes.
"This is an
unprecedented incident that affects deeply the ecosystem, wetlands and
surface water bodies of the region as well as pointing out the fragility
of our drinking water reserves," Gabor Figeczky, the deputy country
officer of the environmental group WWF Hungary, said in a statement.
Environment State
Secretary Illes said there was suspicion that Hungarian Aluminum
Production and Trade Company (MAL), which owns the Ajka reservoir, had
stored more red sludge in the reservoir than was allowed, and that its
walls had displayed stress fractures prior to the spill.
MAL chief Zoltan
Bakonyi insisted, however, that the company had done nothing wrong,
saying the company would suspend all production for the time being.
Prime Minister Viktor
Orban, in a message to the Hungarian people on Tuesday, sent condolences
to the victims' families and promised a thorough investigation to
determine "who is responsible for this man-made catastrophe."

Air quality varies from day to day and year to year, influenced by
both local and large-scale weather patterns. In August 2010, the skies
in many parts of the world were marked by yellow-brown light filtering
down through acrid, smoky air, or by gray-white haze blurring the
horizon. Some of the large-scale weather patterns that dominated in
August are reflected in the top map, which shows aerosols as measured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.
Aerosols are tiny solid and liquid particles in the atmosphere, and MODIS measures them by gauging how they reflect and absorb light, a quantity called aerosol optical depth. When aerosols are dense, they block light from the surface and the aerosol optical depth is high (shown in brown). When there are few aerosols in the atmosphere, light reaches the ground easily, so aerosol optical depth is low (shown in yellow). MODIS does not measure aerosols over very bright surfaces like deserts, ice, or clouds. These areas are gray.
Aerosols enter the atmosphere in a variety of ways, many of which are influenced by weather. Fires send up sooty smoke; wind kicks up dust and sand; and high temperatures cook the chemical soup emitted from tailpipes and industrial processes into a thick haze. High winds, drought, and heat waves can intensify fires, dust storms, and the formation of chemical aerosols.
Some of the highest aerosol concentrations in August 2010 occurred over Russia and South America. In Russia, drought and high temperatures baked plants and soils, making them prone to fire. When widespread fires broke out, they swathed the country in thick smoke. Drought also settled over the Amazon basin in South America, such that fires set to clear trees and brush quickly raged out of control. (See Fires in South America.) The smoke moved north along the Andes Mountains and covered much of South America.
The third area affected by drought was western Canada. While a number of wildfires burned in the drought-dried boreal forest, the smoke aerosols were not as dense as in South America or Russia.
Central Africa is also covered with thick aerosols. The lower image, from August 2009, shows that aerosols routinely gather over central Africa during August, when farmers use fire to clear land for crops and pasture.
The high concentrations of aerosols over northern Africa, the Arabian peninsula, and southwest Asia come from dust. Aerosols in China, Europe, and the United States are haze, largely from industry and automobiles.
Just as aerosol concentrations are influenced by the weather, they in turn can affect weather patterns. Depending on their shape and size, aerosols can either help clouds form or prevent them from forming. Aerosols also reflect or filter light, reducing the intensity of sunlight in a region and making temperatures cooler. They can also block light, absorb energy, and heat the atmosphere.

El Ing. Álvarez en Expo UBA: "la soja no impactó en los suelos pampeanos"
El docente de la Cátedra de Fertilidad y Fertilizantes y director del Laboratorio de Radioisótopos de la FAUBA plantea la temática en el contexto de Expo UBA, en una charla que ofrecerá el próximo 2 de octubre a las 19 en el Auditorio 2 de La Rural (Av. Santa Fe 4201). La inscripción es libre y gratuita y debe hacerse a través del siguiente link http://www.uba.ar/expouba/organizador.php?o=6 Actualmente, de seis cultivos, cuatro son soja, uno es trigo y otro maíz. Si bien se pasó de una planta grande –el maíz- a una tres veces más chica –la soja-, lo que significaría una reducción de los rastrojos -restos de tallos y hojas- que son los que le aportan el carbono al suelo, los rendimientos de los cultivos en rotación no solo no disminuyeron sino que aumentaron. Según el Ing. Álvarez la suba de la productividad se debe al manejo de nuevas tecnologías con las que se logró equilibrar la balanza: "Hoy hay el doble de carbono que hace 40 años, se perdieron entre tres y cuatro centímetros de suelo pero no se ve trasladado en el rendimiento y el aporte de los fertilizantes es responsable sólo del 16% de la producción, el 84 % restante es a partir de los nutrientes del suelo. Por lo tanto, -concluye- creemos que los grados de deterioro en la Región Pampeana son bajos". "Perder suelo, nutrientes, carbono es, obviamente, malo. Pero no suele medirse si esto impacta el rendimiento de los cultivos, por lo que se cae en una lista de datos teóricos que no pueden contrastarse con la realidad", dice quien elaboró un mapa actualizado del carbono de los suelos pampeanos y lo comparó con estadísticas anteriores, que expondrá en detalle en su disertación en Expo UBA. | ||||

Fiesta de Casamiento
Como quizás algunos sabrán, el día 11 de Febrero de 2011, mi novia María Ines y Yo (Andrés Miguel) nos casamos.
Las ceremonias de civil e iglesia se realizarán el mismo día, al igual que la fiesta, en la ciudad que nos vio nacer: San Rafael, Mendoza.
Quiero invitarlos a todos ustedes a participar de este momento.
El costo de las tarjetas es:
Mayores de 10 años: $100.
Niños entre 4 y 10 años: $50.
Menores de 4: $0.
Les pido a aquellos que quieran asistir, que me avisen con tiempo para poder ver si les conseguimos alojamiento en la casa de algún familiar, o si les conseguimos un hotel accesible.
Piensen en tomarse unas lindas vacaciones en San Rafael, Corazón de Mendoza, y de paso, vienen a nuestro casorio!
Con Cariño
Andrés, María Inés y Bruno.
