Agriculture and Agroforestry in South Africa: An Introduction to FarmImpact and the Book
摘要
The special soil and climate conditions at the south-western tip of South Africa pose major challenges for local agriculture. The region is important for the cultivation of grain, but also wine and fruit. To reduce the high local wind speeds, trees have been planted as windbreaks for many years. Especially non-native tree species such as Populus simonii, Casuarina cunninghamiana, and Alnus cordata, but also Eucalyptus species, are often planted as farm trees in the region. These trees also contribute in many ways to ecosystem services and protect agricultural crops. Based on many years of field measurements, FarmImpact develops practical recommendations for action for regional agriculture. On the one hand, this includes the design of water-efficient agricultural practices to improve the water consumption of crops through windbreak hedges. In addition, the aim is to increase soil fertility, reduce soil erosion, and provide additional ecosystem services through integrated measures in the landscape (windbreaks, ecological support zones, land management). Furthermore, the project analyses an increase in economic resilience at the farm level through wind protection measures.
