    Objective:

    According to this article, conservation agriculture is claimed to be a panacea for the problems of poor agricultural productivity and soil degradation in sub-Saharan Africa. Conservation agriculture offers the means that can prevent further destruction of precious soils, increase rainwater use efficiency and labour productivity, thereby ensuring higher and more stable yields.

    Sectors:

    According to this study, a range of land management practices is available to help improve green water use efficiency. These practises can be classified according to their function. Hedgerow barriers and terraces can mitigate runoff; infiltration rates below hedgerows in Kenya were found to be three to eight times higher than where the crop was grown. Mulch that triggers soil fauna can improve water availability; mulching with straw from a local perennial grass in Burkina Faso doubled the water use efficiency from 1 kg mm-1 without fauna to 2 kg mm-1 with fauna.

  • Climate-change mitigation and adaptation in small island developing states: the case of rainwater harvesting in Jamaica

    Type: 
    Publication
    Publication date:
    Objective:
    Approach:

    This essay looks at climate change impacts on small island developing states (SIDS). It argues that climate change adaptation and mitigation strategies must be developed to cope with changes such as shifting precipitation patterns, increasing evapotranspiration and expanding saline intrusion into coastal aquifers and wells.
