This amount includes expenditure in relation to agricultural research, training and extension services, pest and disease controls, veterinary services and disaster aid. It also includes expenditure by other departments such as the Department of Education under the school nutrition programme, classified as domestic food aid. There are other various provisions in the Green Box, related for example to environmental programmes and certain income support measures that South Africa has not made use of. Under these provisions, South Africa may substantially increase its support to the agricultural sector provided certain rules are adhered to.
