adminLakes region, experts say, despite a climate conducive to growing various crops.
“We have a very big challenge within the Central Africa region: can the small land support the population we have?” posited Nteranya Sanginga, director-general designate of the International Institute of Tropical Agriculture (IITA).
At a recent conference organised by the Consortium for Improving Agriculture-based Livelihoods in Central Africa (CIALCA) in the Rwandan capital, Kigali, Sanginga said intensive and relevant agricultural research could help to feed the steadily growing population.
“If we don’t do that, we could be going into a situation of war – war for food, war for space,” he said.
Predominantly small farms, about less than half a hectare, make agricultural intensification – increasing productivity per unit area of land – necessary to help meet increasing food demands.
Two countries in the region, Rwanda and Burundi, have high population densities estimated at about 400 inhabitants per square kilometre.
Outside sub-Saharan Africa, agricultural intensification has largely been driven by combining inorganic fertiliser and agri-chemical inputs with intensive tillage and improved varieties. But experts are recommending more sustainable intensification, involving food systems in harmony with the environment.
“Given the food demand pressures and the environmental constraints (carbon, water, bio-diversity), there seems little alternative to an intensification pathway for agriculture – but it needs to be a sustainable one,” notes a study, Sustainable intensification and the food security challenge, presented at the conference.
Cash and will
In sub-Saharan Africa, where high fertiliser costs mean low usage, rising agricultural productivity has often followed the provision of more land, but this too has its limitations.
“The clearing of forests and woodland and cultivation of grasslands is going to generate a significant load of greenhouses gases on an already overloaded atmosphere – with consequences of climate
change and potential for negative feedback on agricultural productivity,” according to the study.
Besides on-farm approaches, experts at the conference emphasised the need for improved agricultural financing and political will towards achieving regional food security.
“The fact that the green revolution bypassed most of Africa has a reason in finance; the lack of political will is also a reason,” Henk Breman, principal scientist at IFDC a food security NGO, said.
With little government support and weak rural infrastructure, as well as high transportation and fertiliser costs, farmers struggle to switch to high input, high output farming.
According to an International Food Policy Research Institute report titled, Green Revolution, Curse or Blessing, “simply adding to the pile of food will not be enough”.
“Typically, governments must make a concerted effort to ensure that small farmers have fair access to land, knowledge, and modern inputs,” it states, adding that there is a need for agricultural technologies that can profitably be adopted on all farm sizes.
Boosting production
Shem Michael Ndabikunze, director of the Rwanda Agriculture Board, said increased agricultural investment was already paying off in Rwanda where food production has increased in the past few years. He said an emphasis on the value chain, all activities from the field to the market, had helped to boost production. At present, 53 percent of agricultural land in Rwanda is consolidated, meaning that farmers have access to improved seed and subsidised fertiliser, Ndabikunze added.
Rwanda’s food security outlook through to December remains satisfactory, with most markets in the country adequately supplied, according to FEWS NET. Ndabikunze said Rwanda had also increased its public investment in agriculture to 10,1 percent of GDP in 2010, expected to reach 12 percent in 2011. – – IRIN.
