Unregulated land ownership

In many developing countries, agricultural land is occupied and farmed without legal land title. In Thailand, for instance, over 40% of agricultural land is farmed this way. Moreover, especially in rice production, it is common that a large portion of the land is farmed by those who rent fields on short-term contracts. One effect is that the land is used for short-term gains rather than maintenance of long-term productivity.
