This paper is a continuation of a study started in 1963 on major cadastral surveys in the Sudan. Plat agricultural land in developing countries is the main source of economy. It is required that this land be both mapped and demarcated-divided into agricultural plots. However, most of these countries are in a very bad need of reliable maps; some of them have no maps whatsoever. To perform the conventional surveys and maps in order to demarcate the land would be unrealistic in such case.

The purpose, and often the result, of the legislation which has been gradually introduced over the last fifty years has been to replace a system of unwritten customary rights which varied from region to region with a relatively simple system of land ownership based on written and published texts, familiar to all and applicable to the territory as a whole.

African land tenure problems, just like those of the African family, are exceedingly complex and baffling. With its ethnic diversity, Cameroon is an inextricable tangle of different concepts of title to land. Yet, except in the overpopulated areas and some times in the towns, the tensions stemming from land tenure problems were practically unknown in Cameroon until about thirty years ago. Owing to economic development and particularly the overpopulation of certain sectors, and the development of the towns, the government was forced to intervene in land tenure questions.

This Technical Note provides a guide for rounding numbers used in the agreement, narrative and tables of Watershed Work Plans and River Basin Reports. Rounded numbers improve appearance and creditability, and reduces errors and conflicts. Ideas presented herein and in the attachments can serve as a guide. However, they will not rule out the necessity for prudent judgment in each case. Therefore, in review of the examples attached, recognize that rodding of values for a particular Watershed Work Plan must be tailored for that particular plan.
