Despite the possibility of increasing marketable production through the application of agricultural science and technology, Third World rural communities often have little land under planned management and the primary emphasis is on gathering for daily needs. The constant necessity of supplying today's food needs, and difficult access to agricultural land, help maintain the notion that it is not possible to manage long-range production schemes and few efforts are made to produce major cash crops. Poor and impassable roads to agricultural land and hand harvesting methods serve to restrict the amount of land under production. Planting and cultivating those crops that feed the village is often done without considering either national or international markets. Livestock is primarily dependent on foraging for food, and animals are slaughtered primarily for celebration rather than as a part of the regular diet or used as a marketable product.
