income generating activities have, in general, very poor returns. Table C2 shows the numbers of farm households by area of land cultivated by ADD. Poor smallholders tend to have few assets, to use lower levels of purchased inputs than the average and, unsurprisingly, have low access to credit. They grow relatively less hybrid maize and more local maize than average, but in total they plant a higher percentage of their land to maize than better-off farmers, who grow more high value crops. They own relatively little livestock. Virtually all poor households have difficulty meeting their food requirements from own production. On average they produce about 64 percent of their food requirements and the poorest may produce less than 40 percent of their requirements. The land available to them for cultivation is insufficient to produce enough local maize for their needs, they cannot afford to purchase the inputs necessary to put all their land under hybrid maize, and they grow virtually no cash crops. Households rely on off-farm employment, and in particular ganyu (casual agricultural labour) to provide the rest of their food needs, but many households have to reduce their consumption levels in the pre-harvest period.

They face considerable labour constraints in off-farm labour supply, in part due to their higher dependency ratios, but also because of the considerable time spent in domestic activities such as collecting water and wood and pounding maize. Off-farm income is an even smaller share of total income for these
