    In recent years there has been a flurry of activity aimed at evaluating the land useconsequences of biofuels programs and the associated carbon releases. In this paper we argue that these studies have tended to underestimate the ensuing land use change, because they have ignored the role of irrigation, and associated constraints on cropland expansion. In this paper, wedevelop a new general equilibrium model which distinguishes irrigated and rainfed cropping industries at a global scale.

    Among multiple slippage effects potentially generated in voluntary land retirement programs, this study attempts to identify one unique source of slippage. Specifically, I examine slippage caused by within-a-farm land conversion from uncultivated land to cropland. With the U.S. Agricultural Census farm-level longitudinal data on land use and enrollment in the Conservation Reserve Program (CRP), I find that an average partial-farm CRP participant converts 25% of noncropland to cropping activities as a consequence of CRP enrollment.

    In rapidly suburbanizing areas, minimum lot sizes of ten acres or greater are often used to discourage residential development and to maintain agricultural critical mass. Because of significant development pressure in these places, there is a good chance these lot size regulations will bind. Such “down-zoning” often appears alongside the purchase of agricultural and conservation easements that reduce housing development even more. Whatever the benefits of such policies for agriculture and the environment, they raise obvious concerns about housing supply and affordability.

    Consistent and reliable data on farmland values is critical to assessing the overall financial health of agricultural producers. However, little is known about the idiosyncrasies and similarities of standard land value data sources – U.S. Department of Agriculture, Federal Reserve Bank land value surveys, and transaction prices. All three data sources are highly correlated, but transaction prices tend to be higher, especially for irrigated cropland and ranchland.

    Scientists predict that global warming will cause suitable habitat ranges to shift for many plant species, including blue oak in California. If proximity to particular land cover types significantly affects human welfare, any such shifts will affect household welfare, resulting in an indirect cost that is currently unaccounted for in the climate change literature. Using a hedonic pricing model, the marginal values of blue oaks and the land cover types most likely to replace them are estimated at multiple spatial scales using single family residences sold in Kern County from 1997 to 2003.

    The National Commission on Land and Other Properties (Commission Nationale des Terres et Autres Biens or CNTB) in collaboration with the Norwegian Refugee Council (NRC) and its Internal Displacement Monitoring Centre (IDMC) organised a workshop on the role of the CNTB in promoting durable solutions for internally displaced people (IDPs), on 10 November 2011 at Chez André in Bujumbura.

    This chapter is an initial exploration and sharing of experiences and ideas based largely on a case study of a group of small farmers who have occupied and are producing on land that they believe they have an historical right to. The group, called Mahlahluvani – although they include people from other communities and claimant groups – are part of a land claim that has been lodged on the land they now occupy, but the claim is not yet settled.

    The present paper is written as part of the overall VG consultation and development process

    and is a contribution to the subsequent preparation of the Gender Technical Guide. The

    present paper is based both on the outcomes of the VG consultation process to date and on

    supporting research, consultation and literature review on gender and governance of tenure. It

    contextualises and defines gender for the VG, discusses what governance of tenure means
