The United Nations’ Food and Agriculture Organization (FAO) and its Global Soil Partnership have launched a new programme to boost soil productivity and reduce soil degradation for greater food and nutrition security in Africa.
The Afrisoils programme aims to increase soil productivity in 47 African countries by 30 percent, and reduce soil degradation by 25 percent in the next ten years.
Africa is the second driest continent, with nearly half of its surface made up of desert, and 40 percent of it affected by desertification.
About 65 percent of the continent’s farm land is affected by erosion-induced losses of topsoil and soil nutrients. If soils are severely damaged or lost, they are very difficult and costly to restore and rehabilitate.
Less than half of Africa’s land is suitable for agriculture, and of this, only 16 percent is of high quality.
Faced with these challenges, despite progress in improving agriculture, Africa as a whole remains largely food insecure, directly affecting 70 percent of its population who rely on the little available land to grow food and make a living.
Out of the 815 million undernourished people globally, 243 million are from Africa.
According to Rene Castro, FAO’s Assistant Director-General, Climate, Biodiversity, Land and Water Department. “Healthy soil is the foundation of our food system, supporting healthy crops that nourish people. Only with sustainable soil management can we achieve agricultural growth, ensure food security and adapt to a changing climate.”
Many African countries lack policies regulating soil as well as the capacity, knowledge and experience to plan and implement sustainable soil management programmes.
“Afrisoils looks at a mix of soil interventions and the adoption of best sustainable soil management practices, which are focused on increasing the soil organic matter content in African soils to improve soil’s fertility and reduce soil degradation,” said Castro.
We need $50 million to carry out this programme at large scale and for the first ten years. We need everyone’s support for this ambitious initiative, he added
For healthier soils
Ronald Vargas, FAO Land and Water Officer stated that “To render soils highly fertile and in the long term, we need to implement sustainable soil management practices that are of integral nature. We can’t rely only on mineral fertilizers – a common practice around the world – as soil fertility or soil health depends on how we boost the soil system. We need to use smart, long-term solutions that increase soil productivity while safeguarding ecosystem services, and preventing pollution and degradation” .
Some of the Afrisoils programme’s interventions focus on
- Increasing soil’s organic carbon and organic matter, which are essential to soil’s fertility, by leaving crop residues and composts; using crop rotation and diversification to capture the soil’s nitrogen; using natural fertilizers.
- Implementing soil conservation and erosion control measures (such as hedgerows, contour lines, terracing);
- Rehabilitating degraded soils (including remediation of polluted soils);
- Curbing deforestation;
- Using climate smart agroforestry practices;
- Using irrigation for improved crop production;
- Establishing and/or equipping soil testing laboratories;
- Building famers’ capacity to use and adopt sustainable soil management practices;
The Global Soil Partnership Plenary Assembly
The Global Soil Partnership Plenary Assembly (PA) is the main venue where all GSP partners come together to make important decisions about the global soil agenda.
From land users through to policy makers, one of the key objectives of the GSP is to improve the governance and promote sustainable management of soils.
