It is widely understood that maize is the largest locally produced field crop and the most important source of carbohydrates in the Southern African region. Hence in South Africa, the largest area of arable farm land is planted with maize (Botha, et al., 2015). According to Grain SA (2016), more than 9000 commercial maize producers are responsible for the major part of the country’s crop, while thousands of smallholder producers produce the rest.
Furthermore, maize is produced mainly in the Free State, North West and Mpumalanga Highveld, with local consumption amounting to above 8 million tons per annum – the surplus is exported mainly to the SADC region (Grain SA, 2016) .
Given this scenario, the objective of SIP 11 in maize value chains is to a) map maize production by provinces, b) map maize production by farmers categories (commercial and smallholder farmers), c) map road, railway, storage (silos) and millers infrastructure linked to maize production and d) map the ports/harbours and border posts and infrastructure linked to them.
