Globally, farmers remain the key ecosystem managers responsible for increasing food production while simultaneously reducing the associated negative environmental impacts. However, research investigating how farmers’ agricultural management practices are influenced by the values they assign to ecosystem services is scarce in South Africa. To address this gap, a survey of farmers’ agricultural management practices and the values they assigned towards ecosystem services was conducted in the Eastern Cape, South Africa. Results from the survey show that farmers assign a high value on food provisioning ecosystem services compared to other ecosystem services. Irrigation and fertiliser decisions were mostly based on achieving maximum crop yields or good crop quality. The majority of farmers (86%) indicated a willingness to receive payments for ecosystem services (PES) to manage their farms in a more ecosystems-oriented manner. To encourage farmers to shift from managing ecosystems for single ecosystem services such as food provision to managing ecosystems for multiple ecosystem services, market-oriented plans such as PES may be employed. Effective measures for sustainable intensification of food production will depend on the inclusion of farmers in the development of land management strategies and practices as well as increasing farmers’ awareness and knowledge of the ecosystem services concept.

Increased concern for the environmental effects of pesticides has led to considerable interest in optimal management strategies for controlling pest populations affecting agricultural production. This issue has been considered by a number of researchers (Feder and Regev; Hall and Norgaard; Hueth and Regev; Lazarus and Swanson; Marsolan and Rudd; and Talpaz and Frisbie). With the exception of Feder and Regev, these studies considered only one species. This approach involves serious limitations since a grower is generally confronted with multiple species during the production period For example, insect prey-predator relationships may exist in the field (Feder and Regev). Alternatively, as an insect pest develops through a number of growth stages, multiple pests in effect exist (Reichelderfer and Bender).
