Food and Land Use Systems

While Portland, Oregon, gains renown for supporting locally grown, sustainably produced, healthy, or otherwise " good " food, it has failed to ensure equitable access to said food. As parts of the city gentrify, dislocated Portlanders find themselves without access to fresh produce, contributing to health disparities among low-income and minority residents. This research sought to understand issues of food access among populations displaced by gentrification and determine the best locations for produce stands as a method to increase access to fresh produce. It examines the concept of the food mirage by studying the coverage of grocery stores in Portland and proposes an alternative intervention, produce stands, as a pedestrian-scale approach to address gaps in grocery store accessibility for those without transportation. Calculations using geographic information systems (GIS) determine the ideal locations for produce stands in walkable areas not served by transit or fruit and vegetable markets and that house a high number of residents displaced by gentrification. The methodology returns appropriate sites in East Portland, a historically underserved area of the city facing disparities in obesity-related chronic disease. This paper contributes to the research and practice of food systems planning by incorporating indicators of gentrification-driven displacement as well as the built environment into a process of spatial analysis to expand consumption of affordable produce while providing entrepreneur-ship opportunities for disadvantaged residents. Food justice activists can use this methodology to determine areas of need and account for assets of the built environment in order to site a food access intervention that remains largely underutilized in North American cities.

The social-ecological systems (SES) framework was developed to support communication across the multiple disciplines concerned with sustainable provision and/or appropriation of common-pool resources (CPRs). Transformation activities (e.g. processing, distribution, retailing) in which value is added to resource units appropriated from CPRs were assumed in developing the framework to be exogenous to the SES of focal concern. However, provision and appropriation of CPRs are nowadays often closely integrated with the market economy, so significant interdependence exists between many CPR provision/ appropriation activities and the activities in which appropriated resource units are transformed into the products ultimately marketed. This paper presents a modified version of the SES framework designed to better account for transformation activities in order to be more suitable for diagnosing those sustainability problems where it is inappropriate to define all such activities as exogenous to the SES of focal concern. The need for such modification was identified in a research project examining the challenges faced by Cambodian cattle-owning smallholders in accessing value chains for premium-priced beef. Hence the immediate focus was on strengthening the SES framework's value for facilitating a multidisciplinary diagnostic approach to food system research projects of this kind. The modified SES framework's potential in this respect was illustrated by a preliminary application that drew on literature reviewed for the Cambodian project. Significant further potential exists in using the modified framework as a foundation from which to develop a version that is suitable for application to SESs in which transformation systems are appropriately represented as endogenous. Maintaining consistency with the standard SES framework will enable communication to occur more effectively between food system researchers and CPR scholars more generally. 2 Graham R. Marshall

With agricultural areas covering almost half of European land, proper management of agro-ecosystems is key to achieve the European Union's environmental and climate objectives. This requires spatially explicit methods and indicators. We developed an approach for the classification of agricultural land by combining two main dimensions i) land cover, using detailed geo-spatialized census data covering 63 individual crops; ii) management intensity, measured as the anthropogenic energy required in the primary crop production. As a result we identified 10 main crop systems further classified into 30 'crop-management systems' at a spatial resolution of 5 arcminutes. The resulting maps show the spatial patterns of agricultural management intensity across Europe, both in absolute terms (total energy input per hectare) and relative to the dominant crop system in the spatial unit of analysis. The use of multiple intensity dimensions provides new, more detailed insights on agricultural intensity by which areas that were previously classified as low-medium intensive-some permanent crops systems or irrigated arable land-appear now as highly intensive. An expert-based evaluation was carried out on the intensity maps and corroborated the obtained results. The generated maps can be used to support decision-making in designing more targeted, context-specific agricultural and territorial policies. In particular, findings can be relevant in the context of the Common Agricultural Policy post 2020 and the Biodiversity Strategy towards 2030, both of which will benefit from more detailed spatially explicit information to achieve their stated objectives.

Meeting the growing demand for food in the future will require adaptation of water and land management to future conditions. We studied the extent of different adaptation options to future global change in the Mediterranean region, under scenarios of water use and availability. We focused on the most significant adaptation options for semiarid regions: implementing irrigation, changes to cropland intensity, and diversification of cropland activities. We used Conversion of Land Use on Mondial Scale (CLUMondo), a global land system model, to simulate future change to land use and land cover, and land management. To take into account future global change, we followed global outlooks for future population and climate change, and crop and livestock demand. The results indicate that the level of irrigation efficiency improvement is an important determinant of potential changes in the intensity of rain-fed land systems. No or low irrigation efficiency improvements lead to a reduction in irrigated areas, accompanied with intensification and expansion of rain-fed cropping systems. When reducing water withdrawal, total crop production in intensive rain-fed systems would need to increase significantly: by 130% without improving the irrigation efficiency in irrigated systems and by 53% under conditions of the highest possible efficiency improvement. In all scenarios, traditional Mediterranean multifunctional land systems continue to play a significant role in food production, especially in hosting livestock. Our results indicate that significant improvements to irrigation efficiency with simultaneous increase in cropland productivity are needed to satisfy future demands for food in the region. The approach can be transferred to other similar regions with strong resource limitations in terms of land and water.

Forty percent of Switzerland is comprised of agricultural grassland. Due to this large area and the strong effect of management intensity on biodiversity, grassland management is crucial for species richness of the entire country. In 1993, an agri-environmental program to reverse species decline was implemented by the Swiss government. To date, 100,000 ha of meadows and pastures are managed as ecological compensation areas (ECA). The results of investigations to quantify the effects of ECAs on the species diversity of plants, birds and arthropods are summarised. Plant species richness in ECA litter meadows is satisfactory, whereas it is deficient for ECA hay meadows. Whereas the effect on birds is positive or negative, depending on the guilds, while it is mostly positive for butterflies, grasshoppers, carabid beetles and spiders. The results indicate that the measures are only partially successful in enhancing or conserving floral and faunal species richness.

Resumen: En el último cuarto de siglo la dehesa española ha despertado un interés científico que sólo encuentra parangón y justificación en la creciente preocupación de la opinión pública por la conservación y restauración del rnedio ambiente. En poco tiempo, la dehesa ha pasado de ser el paradigma del lati-f~indismo en su más peyorativa concepción, a convertirse en un modelo incuestionable de desarrollo sostenible. Sin negar a priori esta nueva concepción, este artículo trata de ofrecer las claves para una reflexión sobre la sostenibilidad pasada, presente y futura de la deliesa. Y pretende liacerlo desde una perspectiva geográfica, integradora, alejada de modas pasajeras y opiniones estereotipadas.
