This thematic issue of the Land Tenure Journal brings together theories and practices related to land tenure and climate change both from the mitigation and adaptation perspectives. Articles look at the implications that REDD+ and Payments for Environmental Services pose to land tenure and administration, propose approaches to deal with the new challenges and analyse the adaptation of local tenure systems and livelihoods to climate change.

In preparing an investment project, development strategies and project components are defined and revisited during project formulation through a consultative process that often includes Socio-economic and Production Systems Studies.

The Mozambique land law provides statutory recognition of customary land rights and is considered one of the most progressive legislations in Africa.

有保障的权属是可持续森林管理的重要前提条件。更加多样化的权属体系可为改善森林管理、当地生计奠定基础，在森林管理能力较弱的国家尤其如此。过去10年间，很多国家开始改革森林和林地的权属安排，将获取和管理森林资源的权力在不同程度上从中央下放到家庭、私营公司和社区等主体。本书为政策制定者以及森林权属改革的参与者提供了切实可行的指导。书中引用了大量资料，包括粮农组织在非洲、东南亚、拉丁美洲和中亚开展的森林权属评估，得出一些经验教训，并阐明原因。本书列出了10条权属改革指导原则，提出因地制宜通过适应性的方式实现森林权属多样化。本书还强调，成功的权属改革与相关规范框架和治理安排改革相关联，因此必须将其放在更广阔的国家发展议程中来看待。
