This guide has been prepared to familiarize readers with key issues in land tenure, especially as they relate to food insecurity and rural development situations. Land tenure issues are frequently ignored in rural development interventions, with often long-lasting, negative results. Analysis of how land tenure works in practice - as evidenced by who has what type of access to land and under what conditions - is essential. This guide is designed to assist technical officers in governments and civil society in understanding why and how land tenure issues should be considered in rural development projects. It analyses important contexts such as environmental degradation, gender discrimination, and conflicts, where land tenure is currently of critical concern.
