“…These are potential research gaps in WUE assessment in SSA that have been identified here for the first time. Despite the limited number of case studies on this target, available evidence suggest that water policy reforms can lead to an increase in WUE particularly in the agricultural sector (Thiam et al, 2015).…”

Water security in sub‐Saharan Africa: Understanding the status of sustainable development goal 6

The world is nearing the 2030 target‐year by which sustainable development goals (SDGs) should be achieved. While other developing regions seem to be making progress toward achieving SDG6, sub‐Saharan Africa (SSA) is lagging behind significantly, particularly with regard to access to water supply and sanitation (WSS). As a result, most studies evaluating progress toward the achievement of water security SDGs in SSA have focused on WSS while the rest of the SDG6 targets have received scant attention, often using fragmented or incomplete evidence. Here, we fill this knowledge gap by conducting a comprehensive assessment of the status of SDG6 in all 48 countries in SSA. We provide a review of the progress made, the challenges affecting each SDG6 target and examine the different political, socioeconomic, and environmental factors with potential to undermine the achievement of SDG6 in the region. Our review clearly demonstrates that it is likely that most countries may not achieve water security by 2030. The complex nature of the challenges and factors impeding the achievement of water security in SSA outlined here suggests that a holistic intervention involving local, national, and international stakeholders and the research community is urgently needed to address SDG6 if the 2030 target date is to be met. Approaches to enhance water security may equally consider: (a) underpinning peace and security in SSA and (b) the commitment of more financial resources by donors particularly during this period of COVID‐19 pandemic.

“…Several authors have stated that water markets are a strategy to improve water use efficiency (Tanaka & Lund, 2003;Pujol et al, 2006b;Thompson et al, 2009;Solís & Zhu, 2015;Thiam et al, 2015;Manjunatha et al, 2016;Zhang et al, 2016). Trading provides flexibility to farmers as they can adjust the amount of water used according to climatic conditions (Zhang et al, 2016), and encourage water reallocation by adapting users' water consumption levels (Solís & Zhu, 2015).…”

“…Trading provides flexibility to farmers as they can adjust the amount of water used according to climatic conditions (Zhang et al, 2016), and encourage water reallocation by adapting users' water consumption levels (Solís & Zhu, 2015). Water pricing associated with trade also contributes to the efficient use of water resources (Thiam et al, 2015). By reducing water losses due to evaporation or transpiration, trade can strongly impact water use efficiency in irrigated areas (Thompson et al, 2009;Kahil et al, 2015b).…”

The water market is an economic instrument for the water allocation among different users, particularly in locations and periods of water scarcity. Although several authors defend the instrument as beneficial for the conservation and efficient use of water resources, other effects, such as issues of equity, sustainability and environmental impacts need to be assessed. This article focuses on identifying the economic, social and environmental impacts of water markets through a review of the literature. The searches were conducted in Scopus and Web of Science bases, where 235 studies were screened. 48 of these studies were included in the review, and most of them report only economic impacts, such as effects on landowners' income, agricultural production and efficiency of water use. On the other hand, social and environmental impacts were poorly evaluated by the studies. Social impacts mainly include issues of distribution of market benefits and access to water and rights. Of the environmental impacts, the effects on the environmental flow of rivers and reservoirs, as well as on the levels in the aquifers, stand out. It is concluded that the literature is still incipient in documenting the impacts of water markets in terms of diversity of effects, and further studies are needed to assess environmental impacts and equity and justice in access to water.
