    A contingent valuation survey was conducted in two diverse Oregon counties to estimate potential enrollment of framed or grazed land in a riparian buffer strip program. Landowner preferences for various program components were elicited and demonstrate the need to carefully design conservation incentives to encourage participation.

    The Environmental Benefits Index (EBI) ranks Conservation Reserve Program (CRP) offers by weighing program costs for enrolling land in CRP against six environmental objectives. This paper uses Monte Carlo simulations to analyze the sensitivity of CRP enrollment outcome to the specification of the EBI. Results indicate that:(a)there is no major shift in average benefits throughout the U.S.

    We evaluate the impact of agricultural land market liberalization policies in Latin America by empirically examining the degree to which the reforms have broken down the dependence of operational area on owned area. We use panel data sets from Honduras and Peru to estimate the relationship between operational and owned land holdings for pre and post reform periods.

    Scenario analysis was used to develop scenarios the grazed forage industry in the western U.S. will most likely face over the next several decades. Five major factors were identified as being most consequential. Scenarios indicated that livestock use of grazing lands will most likely decline while wildlife use will increase.

    We survey the literature on spatial bio-economic and land-use modelling and review thematic developments. Unobserved site-specific heterogeneity is common in almost all of the surveyed works. Heterogeneity appears also to be a significant catalyst engendering significant methodological innovation. To better equip prototypes to adequately incorporate heterogeneity, we consider a smorgasbord of extensions. We highlight some problems arising with their application; provide Bayesian solutions to some; and conjecture solutions for others.

    The sustainable development of rural areas nowadays faces the challenges of global changes. This paper aims to review the concept of land use and landscape multi-functionality in order to help adapting land and landscape use to the new social, economic and ecological demands. In this respect, the paper utilises the findings of a case study conducted in Bulgaria.The authors illustrate that multi-functionality as a qualitative characteristic combines economic with ecological principles in production and improves the end economic results in the given rural area.

    Chine

    Households in developing countries take various actions to smooth income or consumption as a means of managing or responding to risk. This paper examines migration and land rental market participation as responses to risk in rural China. The authors show that over the last 30 years, there have been significant reforms in China, which have increased labour mobility and the functioning of rural land markets. The authors emphasise that while limitations still remain, the reforms have to date increased the efficiency of the allocation of these important factors of production.

    Brésil

    The rapid increase in global biofuel production and consumption, particularly of ethanol, has an associated derived demand for crops to produce the necessary feedstock. This working paper assess the implications of global biofuel expansion on Brazilian land usage at the regional level.The document reveals that most of the expansion in global ethanol consumption outside the US is met by Brazilian ethanol production.

    Ouganda

    This study investigated the linkages between poverty, agricultural productivity and land degradation in Uganda. Results show that farmers in the study region of Uganda deplete about 1.2% of the nutrient stock stored in the topsoil per year, leading to a predicted 0.2% annual reduction in crop productivity. Replacing the depleted nutrients using the cheapest inorganic fertilizers would cost about 20% of farm income on average. Land investments such as soil and water conservation structures and agroforestry trees were found to increase agricultural productivity and reduce land degradation.
