Land is an essential source of livelihood for a majority of Sierra Leoneans. Most of Sierra Leone’s population lives in rural areas and it’s GDP is largely based on agriculture. The three main livelihood activities surveyed in the 2015 population and housing census are crop farming, animal husbandry and fishery, which depend largely on access to and ownership of land. Smallholders mostly cultivate rice, cassava, cocoa, coffee, cashew, groundnut, palm oil, vegetables and other fruit trees.
Peru shares the main land-related problems of several South American countries: the existence of very large landholdings (latifundios), on the one hand, and small landholdings (minifundios), on the other, in historical processes marked by the interests of actors such as landowners, agro-industrialists, peasants, and indigenous communities. However, unlike some neighboring countries, the dynamics of these elements are different due to a series of particular agricultural policies and their respective results, which have placed Peru as one of the main producers and exporters of agricultural crops in the region.
Conflict is a major cause and, in some cases, result of humanitarian crises. Conflict frequently overlaps with underlying social inequalities, poverty and high levels of vulnerability. Conflicts are direct threats to food security as they cause massive loss of life and therefore loss of workforce (which is particularly important, as agriculture tends to rely heavily on human labour), loss of vital livestock, and loss of land. Conflicts displace millions of people each year, often forcing them to flee with nothing and making them extremely reliant on the communities that offer them shelter and humanitarian aid. This can place unsustainable pressure on hosting communities that often face high levels of food insecurity and struggle to make ends meet.
With secure land tenure, Indigenous Peoples and local communities can realize human rights, achieve economic growth, protect the environment, and maintain cultural integrity. For centuries, Indigenous Peoples and local communities (IPLCs) have used, managed and depended on collectively-held land for food supplies, cultural and spiritual traditions, and other livelihood needs. Historically governed through customary tenure systems rooted in community norms and practices that often go back centuries, governments often consider such community land as vacant, idle, or state-owned property. Statutory recognition and protection of indigenous and community land rights continues to be a major challenge.
