But African soils are fast becoming nutrient deficient with low yields spelling a bleak future for many. Keith Shepherd, soil scientist with the Nairobi-based World Agroforesty Centre or ICRAF, said many factors account for the worrying scenario. “The organic matter in the soil has been mined intensely but supply has been suppressed. There has been low level of nutrient input,” he said. Because of this there isn’t enough nutrient supply for crops. The decline in organic matter has led to soils becoming physically degraded and has accelerated water run-off, which erodes the richer part of soils into water bodies. “This has led to progressive decline in water quality and increased siltation, especially in lakes and dams.”
Another important soil capital, phosphorous, is inherently low and this basic problem has not been addressed in Africa as opposed to other regions such as

“Both policy makers and scientists are now waking up to this,” said Shepherd. The realization is that without reviving the agricultural sector, the majority of people in
“A lot can be done by improving support for farmers, like making inputs widely available, creating credit and supplying higher value crops,” Shepherd pointed out.
One of the ways of addressing the problem, according to Shepherd, is through agroforestry where farmers grow trees on farms along with other crops, and can use or sell products from their trees such as timber or fruits.
There are also trees that fixing of nitrogen in the soil and act as natural fertilizers. Another example is leguminous fodder trees which are grown by farmers in many places, including around
Trees, Shepherd explained, can also be important for stabilizing ecological systems, and farmers can benefit from woodlots and planting trees on boundaries.
The World Agroforestry Centre is now involved in many projects aimed at replenishing the diminishing African soil capital for better yields and improved livelihoods.
“One of our main projects is to contribute to the African Soil Information Service (AfSIS) to enable stakeholders to get better information on problems and opportunities relating to soils in
Through infra-red spectroscopy - whereby light is shone on the soil sample and the reflected light collected back as a spectral signature - together with new similar x-ray techniques, it is possible to get information on the amounts and types of minerals and chemical elements in the soil. From this, the type and quantities of nutrients in a particular area can be determined and the amount of water it can hold and thus helping to advise on optimal soil management.
Through AfSIS, the Centre and its partners are currently involved in soil survey across sub-Saharan
“This program started a year ago and is funded by Bill and Melinda Gates Foundation and the Alliance for a Green Revolution in Africa (AGRA), and is hosted by the Centre’s sister institute, the Tropical Soil Biology and Fertility Institute of the International Centre for Tropical Agriculture (CIAT-TSBF)” he explained. The project is also conducting crop testing trials to see how soils respond to fertilizers. “When we work in a particular country we train national teams from national programmes to contribute to the African Soil Information Service to help improve national services”
Advice to different stakeholders
A key goal of the World Agroforestry Centre says Shepherd, is to give advice to different stakeholders ranging from farmers to policy makers and development banks on constraints faced and appropriate land management interventions, like the right agroforestry and soil management techniques for different types of soils and locations. A key need in getting information to farmers, he said, is the building of national and private extension services for advising farmers on appropriate crops and trees, for example for acidic soils. There is also increasing opportunity, he pointed out, to get information to farmers through local internet services and mobile phone services.
At a national level, the Centre provides advice to governments in planning agricultural development programmes for different areas, in developing policies for protection of the environment, and on the role of agroforestry in these developments.
The Centre’s information is made available to the donor community and development banks to provide guidance on funding and support that they could be directed at agriculture. “Agriculture is vital for economic development, poverty alleviation and basic food security, and there will be a lot of spin-offs like processing of food and tree products for internal and external markets,” said Shepherd.

This should be the new paradigm shift in agricultural growth in the developing world, especially in
“In order to successfully meet challenges of globalization, developing countries, in general, and
He, however, recognized that, as continent with countries having primarily agriculture economies,
It is for this that his department is currently working with Regional Economic Communities, members states, research institutes such as International Livestock Research Institute and IFPRI, civil society organisations as well as development partners to move forward the agenda for research and technology.
Professor Kwadwo Asenso-Okyere, IFPRI’s director for International Service for National Agricultural Research Division said in many parts of the developing world, mostly
The pervasive poverty in many parts of these countries cannot be tackled sufficiently without paying attention to production and market development for agricultural products.
To cope with the demand factors and emerging global issues, actors in the food and agriculture value chain need to innovate to meet the challenges of the 21st century.
“The good news is that there has been steady progress in African agriculture over the last few years with growth rates increasing from 2 percent per annum in the 1990s to about 5 percent in the 2000s,” he told the forum.
But to sustain this, Okyere stated, there is need for extraction of economic, ecosystem and social value from knowledge which involves putting ideas, knowledge and technology to work in a manner that brings about a significant improvement in performance.
A lot of knowledge, he explained, already exist and can be used to improve the livelihoods of the smallholder farmer in the rural settings where more than 50 percent depend on agriculture.
But there are no proper linkages for knowledge mobility from institutions of learning, research and different actors to get innovation to work to advance food and agriculture and this call for new approaches to capacity building.
The first stage of capacity building development, he pointed out, should be at the universities or institutions of higher learning to make them innovate and become efficient.
“It has been demonstrated that students retain 90 percent of concept or method if they teach others, 75 percent if they practice by doing, 50 percent if they are involved in a discussion but only five percent through lectures,” he said.
Scientists and students should talk to farmers and see how best they could infuse their [farmers] indigenous knowledge with those in formal educational systems and pass it on for accelerated agricultural production in the developing world.
The next level of capacity building is that of farmers to make them adopt new knowledge and technologies as well as improve on the existing ethnic agricultural knowledge to step up agricultural growth for food and poverty reduction.
Okyere also said for knowledge to be generated and used effectively for innovation in agricultural development there must be innovators in organizations, institutions, technologies and policies that are involved in the process.
Joachim Von Braun, Director of IFPRI challenged Africa and the rest of the developing world to develop their basic science, build practical technical education programmes on agriculture at higher institutions of learning and tap into existing indigenous knowledge to improve agricultural production for food security and wealth creation for the rural poor.
“Agriculture is a major source of employment in the developing world and also a vital source of food for majority of rural populations,” said Braun
Yet agricultural education and research is not being felt on the ground because of lack direct connection between scientists, students and the smallholder farmer who needs knowledge to adopt innovative methods of farming for increased yields.
Most agriculture students, he explained, do have practical experience and thus the big gap between knowledge and innovation and reality on the ground in the end. Africa, he told meting should make agriculture part of its higher education technical programme as one of the means in innovatively addressing food insecurity and poverty reduction in rural settings.
It should be part of the learning process right from secondary education level and
