GUEST PERSPECTIVE | ZIMBABWE Water Scarcity in Zimbabwe Z imbabwe is a landlocked country located in southern Africa. Climatic conditions are largely sub-tropical with one rainy season that runs from approximately mid-November to early April. Zimbabwe is divided into five agro-ecological regions based mainly on rainfall patterns, soil quality and vegetation type. Rainfall quantity ranges from greater than 1,000 millimeters to less than 450 millimeters within Zimbabwe’s agroecological regions. Only about 37 percent of the country receives adequate rainfall for agriculture, which is the cornerstone of the country’s economy (FAO, 2007). Because Zimbabwe lies in a semiarid zone, precipitation is frequently insufficient to maintain the cultivation needed to support its population and in many cases, evaporation exceeds precipitation. In addition to these biological factors that limit water supply, land and water-use legislation enacted during Zimbabwe’s colonial rule has contributed to the country’s current water scarcity. Colonial legislation included the relocation of blacks to low rainfall regions (Zimbabwe’s present day ‘communal areas’) and the allocation of fertile high rainfall land for privately owned ‘white’ farms (News Africa 2000; Okele 2000; Nicol et al. 2006). The communal areas were densely populated leading to serious land degradation from over-grazing and soil mining. Though the present-day Zimbabwean government has passed legislation to redress these land and water inequities, their efforts have been met with opposition from human rights activists and hindered by the lack of money needed to compensate farmers (Okele 2000).

The people in these regions largely depend on international food aid, while malnutrition and starvation are prevalent (Amaral and Sommerhalder 2004). Palace House Consulting Wageningen, The Netherlands Both Zimbabwe’s economy and the livelihood of rural populations depend on agriculture. Agriculture contributes 11-14 percent of Zimbabwe’s GDP, provides employment to 70 percent of the population, and provides 60 percent of all raw material inputs for the manufacturing industry (Zimbabwe Ministry of Foreign Affairs). Agriculture in Zimbabwe’s communal areas is predominantly rain-fed, so precipitation levels play a critical role in agriculture production, economic performance and domestic food security. Communal farmers in Zimbabwe are the most impacted by water scarcity. Eighty percent of communal farmers live in the driest regions of the country, and where rainfall is erratic farmers must rely on surface water from shallow rivers for irrigation (Nicol et al. 2006). These farmers primarily grow food crops such as maize, wheat, beans, tomatoes and vegetables (Nicol et al. 2006). For example, communal farmers who live around Beitbridge, Chiredzi and Gwanda in the Limpopo basin (regions IV and V) experience a short and intense rainy season more often. Rain-fed agriculture, livestock production, and remittances are the main sources of livelihood in these areas (ALM 2007). The regions’ chronic water scarcity results in crop Water scarcity also impacts the welfare of livestock in Zimbabwe. Communal livestock in Zimbabwe depend on natural pasture for grazing; however, water scarcity has led to a browning of pastures with frequent dusty patches. Loss of livestock has been recorded because of lack of pasture and water (Reliefweb 2003). Lastly, water scarcity in Zimbabwe has resulted in water-rights conflicts between farmers. For example, on the Nyanyadzi River in Chimanimani district (region I), farmers downstream of the river frequently clash with upstream farmers over access to water (Farm Radio International 2000; Bolding and Nyagwande 1998). In the communal areas around Plumtree (area southwest of Zimbabwe; region IV), there have been conflicts with communities in the neighboring country, Botswana, over water for livestock and domestic purposes (Banda 2008). Water is a critical resource that supports Zimbabwe’s economy and enables the well being of Zimbabwe’s population. Conflict and scarcity over water in Zimbabwe hinders the livelihood of people, while putting the country in economic jeopardy. 111
