The sub-continent has a tremendous amount of fresh water available, in the form of its enormous rivers and deep groundwater reserves. The soil is incredibly fertile, with 67% of land arable. The mountains have significant deposits of coal, gold, diamonds, iron, and limestone. 32% of Lokmei's geographic area consists of forests, much of it in wet areas, enabling rapid growth of forest farms. The natives manage the forests carefully, permitting only the occasional thinning. The majority of lumber comes from a series of forest farms, with trees carefully bred for their exceptional qualities for firewood, construction, paper, gum, spices, herbs, or drugs. Lokmei's extensive waterways and high biodiversity make for a long and economically significant tradition of fishing and aquaculture. Certain of Lokmei's fish are considered exotic in interplanetary markets, often fetching high prices.
