More than 80% of annual water withdrawal in southern Africa is for agricultural purposes. Much of the region experiences semi-arid to arid climates and water resources vary considerably. In many countries water managcmcnt is complicated by the frequent recurrence of droughts. Improved management of water resources is a pre-requisite to future development in the region. This paper presents the concept of Integrated Water Resources Management (IWRM) which has been widely proffered as a modern approach to water management that will ensure long-term benefits whilst simultaneously protecting the environment and ensuring sustainability. The implications of IWRM for agriculture in southern Africa are assessed. Benefits for the agricultural sector include reduced vulnerability to climatic variability, improved productivity and a more rational and transparent approach to decision-making. However, there remain many constraints to the application of IWRM including lack of quantitativc information pertaining to water use and a wide range of institutional and other socioeconomic harriers. An evaluation of changes required to introduce IWRM within the agricullural sector, under arid and semi-arid conditions, is presented.

The history of dam construction in Zimbabwe dates back to the 1920s and since then over 7,000 small dams have been constructed countrywide. Small dams are multipurpose structures used for improving rural livelihoods. The multipurpose nature of these dams has largely gone unquantified in terms of importance of the uses to the community and influence of management practises. The current study made use of a questionnaire among small dam users, key informant interviews, secondary data and observation on four communal dams in the Limpopo basin to establish the uses, volume of water abstracted and water productivity for some uses and the interrelationship between various organisations and the community in the management of small dams. Uses on all dams in order of importance were livestock watering, domestic use, irrigation, fishing, brick making, and collection of reeds used for roofing. Livestock consume on average over 70% of water for consumptive uses. Water productivity in terms of yield per volume unit of water used ranged from 0.025 kg m-3 for vegetables to 7,575 kg m-3 for bricks, and monetary values per volume unit of water used were Z$ 389,434 m-3 for brick making and Z$ 1,874 m-3 for irrigation. Traditional leadership and the community are pivotal in the management of the small dams, with some organisations giving technical, financial and input assistance. The management and conservation of small dams needs to be well coordinated between the communities, NGOs and government if the full benefits of these national resources are to be realised in the long term.

Some rural populations are dependent on small reservoirs for their water supply and are concerned about the quality of this water for direct consumption and other uses. Chemical and biological water quality measurements can be made to ascertain the suitability of water for different uses. Water “suitability” of course, depends on the use for which it is intended. This tool describes selected methods for assessing the suitability of reservoir water quality.

Increasing agricultural productivity has always been a prominent feature on the regional agenda due to a high incidence of food and nutrition insecurity. This review assessed the current status of irrigated agriculture in southern Africa from a water–energy–food (WEF) nexus perspective. Gaps and opportunities for improving irrigated agriculture within the context of the WEF nexus were also assessed in terms of the feasible limits to which they can be exploited. Southern Africa faces water scarcity, and climate projections show that member states will face increased physical and/or economic water scarcity by as early as 2025, which will have negative impacts on water, energy and food production. Recurrent droughts experienced across the region reaffirm the sensitive issues of food and energy insecurity as well as water scarcity. Projections of an increasing population within the region indicate increased water, energy and food demand. With agriculture already accounting for about 70% of water withdrawals, increasing the area under irrigation will place additional demand on already strained energy grids and scarce water resources. This poses the question—is increasing irrigated agriculture a solution to improving water access, food security and energy supply? While there are prospects for increasing the area under irrigation and subsequent improvement in agricultural productivity, adopting a WEF nexus approach in doing so would mitigate trade-offs and unintended consequences. Consideration of the WEF nexus in integrated resources planning and management eliminates the possibilities of transferring problems from one sector to other, as it manages synergies and trade-offs. While it is acknowledged that improving water productivity in irrigated agriculture could reduce water and energy use while increasing yield output, there is a need to decide how such savings would then be reallocated. Any intervention to increase the irrigated area should be done in the context of a WEF nexus analytical framework to guide policy and decision-making. Technical planning should evolve around the WEF nexus approach in setting targets, as WEF nexus indicators would reveal the performance and impact of proposed interventions on any of the three WEF nexus components.

Water adequacy is central to maximised agricultural production in irrigation schemes. Smallholder Irrigation Schemes (SISs) are designed to distribute water efficiently, adequately and equitably. Water governance, defined as the institutions, processes, procedures, rules and regulations involved in water management, plays an important role in water allocation and subsequently water adequacy. The intersectoral institutions involved in water governance in SISs, i.e., government, Water User Associations (WUAs), Irrigation Management Committees (IMCs) and traditional authorities, interact to formulate and design policies for running SISs. However, multilevel interaction amongst the active stakeholders at multiple levels shapes policy and underlies SIS performance. This research aimed to investigate the impacts water governance had on adequacy of water in irrigation schemes and was premised on the hypothesis that governance had no effect on water adequacy. Water adequacy describes water supply relative to demand. Adequacy indicates whether the water delivery system supplies the required amount to a section in the irrigation scheme over a period of time (daily, monthly or seasonally). Two irrigation schemes, the Mooi-River Irrigation Scheme (MRIS) and Tugela Ferry Irrigation Scheme (TFIS) were used as case studies. A descriptive analysis showed that 86% of the farmers in the TFIS had adequate water, whereas 24% had water adequacy in the MRIS. A Binary Logit model was employed to investigate the factors that influence water adequacy among irrigators. The regression model identified eight statistically significant factors that influenced water adequacy: the irrigation scheme, location of plot within the scheme, training in water management, training in irrigation, SIS irrigators’ knowledge about the government’s aims, availability of water licences, payment of water fees and satisfaction with the irrigation schedule. The study concluded that governance factors had influence on water adequacy in the selected SISs. The implication is that stakeholders should make irrigators aware of government Irrigation Management Transfer (IMT) policy and strategies. The study recommends that the SISs introduce rules, procedures and protocols to support irrigators to enhance scheme governance and lead to the realisation of government policies.
