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.

On all islands in the Republic of the Marshall Islands (RMI) rainwater is the primary source of freshwater, putting the country at high risk from droughts. The water sector was therefore chosen by the RMI Government to benefit from the Pacific Adaptation to Climate Change (PACC) project which has been working since 2008 to increase the country’s resilience to drought events. The island of Majuro was selected as the site for the project as it is the most densely populated area in the RMI.

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.
