Land degradation is a major problem in almost all the countries. In most of the developing countries, population pressure and small farm sizes, land tenure insecurity, land redistribution, limited access to credits and limited education are the factors leading to unsustainable land management. In Ethiopia, among many factors, tenure insecurity is considered as a main problem for land degradation. The frequent land redistribution and the changing pattern of land ownership with the change in Government made the farmers insecure of their land resulting in not making land related investments. Considering this fact, the Government of Ethiopia started the Rural Land Registration and Certification Programme (RLRCP) since 1998/99 to provide land titling and tenure security to the farmers. The studies conducted to show the relation between tenure security and investments on land management show mixed results. There are cases where tenure security plays role in making investments on land management and there are also cases where tenure security has no any role in making such investments which made it difficult to draw a conclusion.
