This book is devoted to addressing land use concerns in developing countries, mainly in Cambodia, as land encroachment and grab has worsened the livelihood of the poor that depend solely on their land resources. Indeed, much dedication is directed to the upland use patterns that are evolving unsteadily, subject to the foreign influence that is sometimes bad for local economies. Therefore, exploration of a variety of land use is key to dynamically raising rural awareness in terms of social, economic and political assistance, so as to plan agricultural work wisely.
