Irrigation, Tomatoes and a Cereal Deficit
An irrigation scheme in a semi-arid district was designed to supply 600 hectares. After five years, 380 hectares are irrigated. Farmers with plots near the main canal grow tomatoes for a processor, earning cash but buying staple maize. Farmers at the tail end receive water only in wet months and grow sorghum for home consumption. A women's cooperative has 40 members but only six have land titles; they farm rented plots. Post-harvest losses for tomatoes reach 30% in peak season because the processor's collection truck comes twice weekly and cold storage is limited. The scheme's water users' association is chaired by the largest tomato farmer. The district food security office reports that three wards had a 20% cereal deficit last year despite the scheme.
1. Explain how the irrigation scheme can coexist with a 20% cereal deficit in three wards.

A scheme can irrigate 380 of 600 hectares and still coexist with a cereal deficit because irrigation does not automatically produce staple food. Near-canal farmers grow tomatoes for cash and buy maize; if local maize supply is thin, cash income may not guarantee food because prices rise or markets are distant. Tail-end farmers receive water only in wet months, so they cannot reliably produce irrigated cereals. The women's cooperative has insecure tenure and rents plots, which discourages investment in soil and water management.
Tomato losses of 30% reduce the value farmers actually capture. The water users' association is chaired by the largest tomato farmer, so allocation may favour near-canal plots. Three wards may also lie outside the scheme's command area.
The deficit is therefore a distribution and production-mix problem, not simply a water shortage. A food security assessment should compare cereal production, purchases, prices and household consumption by location, rather than assume that scheme water equals food availability.
2. Evaluate whether the tomato expansion is good for rural livelihoods.

Tomato production can raise incomes and create employment, especially for near-canal farmers and the processor's workers. But the evaluation should ask who bears the risks. Farmers depend on one processor that collects twice weekly; a delay or price change can leave 30% of the crop unsold. Growing tomatoes uses land and water that might otherwise produce maize or sorghum, so households become buyers of staple food. If maize prices spike, cash income may not protect them. Women's limited land titles mean they may not control the income from rented plots. The association's chair, as the largest tomato farmer, can influence water allocation in ways that entrench advantage.
On balance, the tomato expansion is likely positive for households with secure water, land and contracts, but risky for tail-end and tenant farmers. A judgement should recommend contracts with price floors, cold storage or more frequent collection, staggered planting, and a protected allocation of water and land for staple crops. Without those, higher gross output may coexist with greater food insecurity.
3. Recommend three changes to the scheme's governance and infrastructure that would improve food security and equity.
Read the worked answer
First, reform water allocation: publish a seasonal schedule with enforceable shares for head-end and tail-end users, and give tail-end farmers a formal seat on the water users' association. The chair's dual role as largest tomato farmer should be separated from allocation decisions.
Second, invest in post-harvest infrastructure: a small cold room or more frequent collection, plus training in grading and staggered planting, would cut the 30% tomato loss and raise returns.
Third, secure tenure and inclusion: register the women's cooperative's rented plots or provide written leases, and allocate a share of irrigated land or water to staple food production. A food security office could monitor cereal prices and household consumption in the three deficit wards, with a trigger for releasing food stocks or cash.
These changes address equity, not just output. They are feasible if the scheme's management and the district council share costs, and they would make the scheme's contribution to food security visible.
