    Two images have dominated the northern media in recent months.The first is of desolation in remote, rural areas in Africa affected by drought, conflict or famine, such as in Somalia, northern Kenya or Darfur, Sudan. The second is a different kind of desolation - that of urban squalor as portrayed in the film «The Constant Gardener».

    Malí, África, África occidental

    Soil and water conservation (SWC) practices like that of erosion control and soil fertility measures were commonly practiced in the semiarid region of southern Mali since the 1980s. The SWC practices were mainly meant to increase water availability in the subsurface, reduce farm water runoff and gully formation and improve nutrient content of the soil, thereby increasing crop yield. Despite such efforts to promote at scale SWC practices, the landscape of southern Mali is still affected by high rates of runoff and soil erosion and low crop yield in farmers’ fields.

    Rhamphicarpa fistulosa is a facultative hemi-parasitic plant of the Orobanchaceae family, adapted to wet soils. Apart from tropical Australia, it is only found in sub-Saharan Africa, where it is considered a minor weed in cereal crops such as rice. Due to this status, the species has received only sporadic attention. Recent field observations and encounters with rice farmers in several African countries showed that R. fistulosa is, however, a more serious and increasing production constraint than previously thought.

    This project is about showing whether BSM are effective. It seeks to quantify the consequences of BSM-driven changes in land and water management for livelihoods in upstream rural communities, and for water supplies for downstream water consumers. It will develop methods to anticipate ex ante the likely consequences of introducing BSM as well as monitoring and measuring these consequences ex post.

    ACES is a three-year (2014 -2017) research project that is being implemented in Mozambique with the main purpose being to contribute to poverty alleviation in Mozambique by co-producing new knowledge of the dynamic links between land use change, Ecosystem Services (ES) and the wellbeing of the rural poor and thereby meet the demand from policy makers and practitioners for ways to better manage Mozambique’s woodlands (Dewees et al. 2008; Wiggins et al. 2012).
