Notes: Rainfed agriculture potential(crops, grazing, forest) is classified as high, medium or low (H,M,L). Rainfed potential, closed forest, intensively irrigated, and protected areas are all classified into high (H) and low (L) market access areas. Thus ML is medium rainfed agricultural potential areas with low market access.
