In this paper, we investigate the impact of various socioeconomic conditions on the value of timber tenures in the province of British Columbia. Two timber tenure models were created, one for short-term timber sale licenses and the other for longer term forest licenses. The short-term model revealed that timber sales that were awarded according to a combination of employment, revenue, and manufacturing criteria yielded $8.63/m3 less revenue than timber sales awarded based on revenue alone.

Protected areas are intended to conserve biodiversity by restricting human activities within their boundaries. However, such restrictions are difficult to enforce fully in many tropical parks. Improving regulatory enforcement requires an understanding of prevailing challenges to detection and sanctioning activities. Drawing from empirical field research in 15 Colombian parks, I show that current enforcement efforts may be insufficient to deter most priority threats.

Recent research underscores the continued importance of gender in rural Africa. Analysis of interactions within households is becoming more sophisticated and continues to reject the unitary model. There is some evidence of discriminatory treatment of girls relative to boys, although the magnitudes of differential investments in health and schooling are not large and choices seem quite responsive to changes in opportunity costs. Social norms proscribing and prescribing male and female economic behavior remain substantial, extending into many domains, especially land tenure.

The social and economic consequences of horticultural product food losses from farm to the consumer remain unacceptably high. In developing countries postharvest losses compromise food security, income generation and poverty alleviation for millions of families. In developed countries substantial product losses result in economic losses to supply chain participants and reduced supplies of healthy products into international markets.

The objective of this article is to provide new empirical evidence on landlord-tenant choices of share versus cash-rent contracts in U.S. agriculture. The focus is on the contribution of explanatory variables that represent transaction costs, risk-sharing incentives, or both. An empirical model of contract choice is tested against the 1999 Agricultural Economics and Land Ownership Survey (AELOS) and finds mixed evidence for low transaction cost and risk-sharing-incentive motives for landlord-tenant choices of a share versus cash-rent contract.

The use of non-invasive long-term monitoring data to estimate home ranges of the critically endangered Iberian lynx has been evaluated. This programme began in 2002 and consisting of both annual latrine and camera-trap surveys, with the aims of detecting and individually identifying the maximum number of individuals and delineating female home range boundaries. Radio-tracking data were used to evaluate the accuracy of home range estimates constructed with camera-trapping data.

Kangayam grassland in the tropical region of south India has been sustainably managed for over one hundred and fifty years. In a region with meagre rainfall, growing grass is the farmers' main vocation. Between 1855 and 1881, the majority of government 'wastelands' were given on lease to farmers who organized the land into grazing paddocks and fenced with hedges of Balasmodendron berryi. Numerous wells were dug in the grazing lands to provide water for drinking to animals and to some extent for irrigation.

Assessing factors influencing phosphorus (P) availability in soils is important in preventing its overexploitation and excessive application in agricultural systems. Despite high historical P applications in the federal state of Brandenburg (Germany), county data on soil test P (STP) reveal considerable disparities in soil available P. In addition, negative soil balances as a result of small mineral P and manure inputs have been observed, raising questions about the factors leading to this situation.
