    Net farm income for most representative farms in 2009 will be lower than in 1999. Low profit farms, which consist of 25% of the farms in the study, may have negative net farm income throughout the forecasting period, and may not have financial resiliency to survive. This is true under bothoptimistic and pessimistic scenarios. All farms, except low profit farms, may perform well under the optimistic scenario, while only high profit and large size farms may be able to survive under the pessimistic scenario.

    Bolivie, Norvège

    This paper compares and contrasts patterns of land tenure, property boundaries, and dispute resolution regarding property using examples from two diverse social and economic regions: Bolivia and Norway. The goal of the paper is essentially a comparative one. By placing the examples of Bolivia and Norway side by side, the authors hope to shed light on common strategies while recognizing the diversity to be found in the ways that people relate to land. It is hoped that readers will be able to compare the material here with examples from other regions.

    While agricultural land preservation programs seek to maximize number of acres, to preserve productive farms, to preserve contiguous farms, and to preserve threatened farms, they are often evaluated solely on the number of acres preserved. Using a Farrell efficiency analysis, preserved parcels in four Maryland counties were evaluated for all four goals. Comparisons are made between program Econometric analysis used these efficiency measures as dependent variables. Parcel size and productive farms were the most frequently used criteria to determine efficiency.

    A programming model is used to assess the welfare effects of regional and practice specifications contained in New York State's Draft Conservation Reserve Enhancement Program (CREP) proposal. Net social benefits are nearly 75% lower than options that explicitly account for opportunity costs of production, environmental benefits, and participation response functions.Keywords: benefit cost analysis, conservation programs, participation, linear programming

    The major purpose of this paper is to explore the potential value of benefit–cost evaluation for stormwater quality management decisions at a local level. A preliminary benefit–cost analysis (BCA) screening method is used for maximum extent practicable (MEP) analysis, identifying promising management practices, and identifying societal and economic tradeoffs for local stormwater problems. Ballona Creek, a major urban storm drain in Los Angeles, California, USA, is used to illustrate the practicality of the benefit–cost evaluation.

    Bracken is often perceived as a widespread and increasing land management problem. The pollen record of a wide range of sites in Great Britain suggests that the current abundance of bracken is less than or, at worst, equivalent to maximum historical levels. Recently gathered data also suggest that bracken cover is declining. Results of risk assessments of land use change, and experimental and modelling investigations into the effects of climate change are synthesized.

    The Belgian climate policy is formulated at the federal level, requiring cooperation between regional and federal administrations. Around a fifth of the total area of Belgium is covered by forests. Around 80/ of the productive forests are in the Walloon region. Reported values for land use change and forestry categories give a potential of 2,057 kt eq. CO2 per year. Given the existing regional forest inventories (RFI): RFI1 for 1984 and RFI2 for 1999, an estimate has been made to consolidate reported data.
