To address challenges of agricultural production on extremely sloped land, projects have promoted the use of SALT technology. SALT, Sloping Agriculture Land Technology, helps minimize soil erosion in hilly agricultural areas. A number of SALT methods exist, including alley cropping systems, silvopasture (the combination of forests and livestock grazing), windbreak and shelterbelt plantings, riparian forest buffers, and forest farming systems. The SALT system helps restore soil structure and fertility, thereby improving food production success.
