Improved security of tenure for land and property can make a critical contribution to ensuring social and economic progress in rural and urban settings, supporting poverty reduction and furthering gender equality and peace and security. Land tenure, including a range of tenure types appropriate to local conditions and needs, such as community property rights and the protection of resource commons, creates certainty about what can be done with land or property and its use and can increase economic opportunities and benefits through investment.  Key United Nations entities engaged in issues relating to land and property include United Nations Environment Programme (UNEP), United Nations Human Settlements Programme (UN-Habitat), United Nations Development Programme (UNDP), Department of Peacekeeping Operations (DPKO), Food and Agriculture Organization of the United Nations (FAO) and United Nations Commission on International Trade Law (UNCITRAL).
