The paper reveals that ever since the 1950s, after the first land reform of distributing landownership (or possession under public ownership) to small farmers, the irrational and polyopolisticland use by able-bodied part-time and absent small farmers earning higher off-farm income butunwilling to lease the under-producing land beyond their family consumption need to full-timefarmers, has been a global obstacle with both public and private land ownership, traditional andmodern agriculture, fragmented small and consolidatorily enlarged land, low and high incomeeconomies, food under-self-suffi

Much information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest. Most of this forest type was initially harvested for timber and then cleared for cattle in the last century (1930–1970).

The Northwest Forest Plan was implemented in 1994 to protect habitat for species associated with old-growth forests, including Northern Spotted Owls ( Strix occidentailis caurina) in Washington, Oregon, and northern California (U.S.A.). Nevertheless, 10-year monitoring data indicate mixed success in meeting the ecological goals of the plan.

Emerging concerns for environmental flows translate into reforms that aim to preserve minimal flows in rivers. These policy measures have consequences for traditional right-holders: how to share between consumptive users the new scarcity created by the protection of instream flows? This paper compares different policy mechanisms in France, Australia and California in an attempt to answer the questions of how to allocate water restrictions and compensations and how to pursue simultaneously efficiency, equity and acceptability objectives.

Mangroves are an imperilled biome whose protection and restoration through payments for ecosystem services (PES) can contribute to improved livelihoods, climate mitigation and adaptation. Interviews with resource users in three Solomon Islands villages suggest a strong reliance upon mangrove goods for subsistence and cash, particularly for firewood, food and building materials. Village-derived economic data indicates a minimum annual subsistence value from mangroves of US$ 345–1501 per household.

The spatio-temporal distribution of land cover provides fundamental data for global climate and environmental change research. In recent decades, five global land cover maps have been produced based on remote sensing data sources and methodologies. Related research have shown that the availability and quality of the first four global land cover datasets are poor at the regional or the continental scale for a variety of reasons. There is still no consensus on the accuracy of the latest global land cover map.

This study examines the determinants of income diversification of farm households in the United States. Farm households allocate their time between farm and off-farm activities to help stabilized household income (consumption). What characterizes those households who engage in off-farm activities? Is there any pattern over time? Using 1999, 2003 and 2007 farm-level data from the USDA’s Agricultural Resource Management Survey (ARMS), this study estimates intensity of off-farm income (or income diversification).
