The articles in this volume supplement FAO Land Tenure Studies 10, Compulsory acquisition of land and compensation. The latter publication explains what compulsory acquisition and compensation are and what constitutes good practice in this area.

The issue of compulsory acquisition from a human rights perspective is also addressed here as are the concepts of market value, compensation value and just terms compensation.

Countries retain powers of compulsory acquisition in order to enable governments to acquire land for specific purposes. The nature of these powers and the ways in which they are used are invariably sensitive and have wide implications, including from the perspective of international agreements on human rights and their national expressions. Compulsory acquisition is disruptive for those who are affected and whose land is taken and, if done poorly, will have serious negative impacts on people and their livelihoods.

This document analyzes the implications for land tenure and land policy of climate change. It assesses the implications of ongoing anthropogenic climate change resulting from greenhouse gas emissions for land tenure and the role that land policy can play in climate change adaptation planning in the developing world; it also sets out a simple framework for tracing the linkages between climate change, impacts on land use systems, and the land tenure implications, including those which result from adaptation and mitigation responses to global warming.
