The urban forest provides valuable ecosystem services for enhancing human well-being. Its structure and composition determine the quantity and quality of these services. There has been little research on the heterogeneity in structure and composition of urban forests in the Australasian region, especially in the centre of a highly dynamic and rapidly urbanizing city. This paper quantifies the structure and the composition of the urban forest of Melbourne, Australia's city centre.

O desenvolvimento da agricultura e da pecuária na Amazônia tem resultado na expansão dos desmatamentos, o que contribui para emissão de gases de efeito estufa na atmosfera e redução da biodiversidade. A evolução dos desmatamentos realizada pelos produtores rurais é condicionada por características das famílais produtoras e pelo ambiente socioeconômico. O objetivo desse estudo foi identificar os condicionantes de desmatamentos nos principais pólos de produção agropecuária familiar no estado do Acre. Foi utilizado o modelo econométrico logit multinomial para essa avaliação.

The enclosure system is an increasingly popular approach for land rehabilitation among communities inhabiting the arid and semi-arid lands in Africa. However, the mixed results associated with its adoption by households call for an in-depth understanding of the management regimes.

When South Africa's land reform programme finally reached rural Umbumbulu, a potential for conflict over land emerged unexpectedly. Strategically located near a major urban centre, residents of this region have long relied on wages and social welfare grants. Land was valued primarily for residential security and as a symbolic representation of community membership, rather than for productive purposes. This emphasis on community membership, however, created the potential for conflict when a local chief challenged a civil society group over their authority to claim land.

Facing the general trend towards larger but fewer farms since 1935, the US government implemented a protective safety net for small farmers during 1933-96 which did not halt it but incurred market distortions and other drawbacks. It then switched to market oriented measures in 1996 which have made small farmers more exposed to market risks. A suitable solution to both preserving small and strengthening large farms has not been found.

Family land is a form of communal tenure found in some of the countries of the English-speaking Caribbean inclusive of Trinidad and Tobago. It has been problematic to administer, is sometimes the source of land conflict and litigation, it has been seen as the cause of many land-related problems such as land degradation and fragmentation, and has therefore been targeted for eradication by land title registration programmes. Informal occupation of many years standing on state and private land is also widespread in Trinidad and Tobago.

Using an analysis of aerial photographs from 1942, 1985 and 2004 we assessed the impact of changing land tenure and land-use regimes on the cover of thicket vegetation on the Grahamstown commonage. Land-use impacts were examined by comparing plant species composition within three vegetation types between sites incorporated into commonage for different lengths of time and sites outside the commonage. Results showed that thicket cover increased by 87% between 1942 and 1985 but declined by 11% between 1985 and 2004.

Among the Dayak people in East Kalimantan, simpukng (“forest gardens”) are an important component of their traditional farming systems. Simpukng is managed secondary forests in which selected species of fruits, rattan, bamboo, timber and other plants are planted. While most are owned by families and passed down from one generation to the next, some are managed on a communal basis. Complex customary Dayak rules exist that control the use and inheritance of these forests that help to avoid over-exploitation of resources.

The problem of allocating cutting rights among competing licensees in Canada often entails assigning large discrete units of land to these licensees, typically for periods of fifteen to twenty-five years. The units of forest land are often large because it is economically infeasible for firms to maintain roads and operations widely dispersed across a forest. The assignment of these areas clearly frustrates the economic objective of sending the “right log to the right mill”.
