An agricultural system which combines crop production with forest establishment is known as?

The agricultural system that combines crop production with forest establishment is called "taungya farming." In taungya farming, farmers grow crops like maize, beans, or vegetables alongside the establishment of a forest. The forest is established by planting trees in between the crops, which helps to improve soil quality, reduce erosion, and provide shade for the crops. Once the crops have been harvested, the trees continue to grow, providing timber and other forest products. This system is commonly used in tropical regions where there is a high demand for food and timber but limited land available for cultivation.
