Lunch Seminar: Agricultural intensification in the Sahel

Agroforestry is a low cost foundational practice to increase agricultural productivity and set the stage for further intensification. If used in combination with water harvesting, organic manure and micro-doses of good quality fertilizer yields in drylands can increase greatly. This was a key message of Chris Reij, Senior Fellow Global Restoration Initiative at the World Resources Institute, who gave a presentation during a lunch seminar organized by the Ministry of Foreign Affairs. »

Livelihood and climate trade-offs in Kenyan peri-urban vegetable production

This study investigates productivity and economic and climate trade-offs in soil fertility management strategies in smallholder African indigenous vegetable production in Kenya. Soil fertility management strategies that mix inorganic and organic source present a pathway to sustainable intensification in AIV production. »

How can we measure the health of soil simply and cheaply?

This blog describes two mechanisms to adapt soil health indicator technologies in a simple way and at lower cost, so that they can be applied by smallholder farmers themselves to evaluate the effect of different varieties of tropical forages and their management on the health of their own farm. »

Multi-scale measurements show limited soil greenhouse gas emissions in Kenyan smallholder coffee-dairy systems

This article aims to quantify soil greenhouse gas emissions at different spatial (between farms, among fields within farms, and between fertilised and unfertilised locations within fields) and temporal scales (between seasons, wet and dry periods) in smallholder integrated dairy-coffee systems in Kenya. »

Tropical soils degraded by slash-and-burn cultivation can be recultivated when amended with ashes and compost

This article tests a selective slash-and-burn agriculture (some trees are intentionally not cut), coupled with compost amendment in the dry region of Madagascar. Slash-and-burn agriculture is considered as a driver of deforestation; the forest is converted into agricultural land by cutting and burning trees. Therefore, the authors propose a reclamation strategy for abandoned fields allowing and sustaining re-cultivation. »
