This chapter proposes an exploratory gravity accessibility analysis applied to urban goods transport in Lyon, France to support public decision choices in terms of retailing land use. The proposed indicator is shopping-trip oriented but with a viewpoint of urban goods transport: it considers freight generation (i.e., commodity quantities) at destination and travel issues between household locations and retailing areas for shopping purposes. First, an overview of accessibility used in both urban personal and goods mobility is made, and the proposed analysis motivated. Second, the main methodological elements are presented, focusing on the modelling issues mobilized for indicator construction. Third, the analysis is applied to the current situation for the urban area of Lyon. Results are presented and discussed. Finally, recommendations to public authorities for land-use and mobility (both for people and goods) policy assessment are proposed.

Ecosystem services (ESs) is a term used to describe the foundations of the well-being of human society, and several relevant studies have been carried out in this area. However, given the fact that the complex trade-offs/synergy relationships of ESs are a challenging area, studies on matching mechanisms for ES supply and demand are still rare. In this study, using the InVEST model, ArcGIS, and other professional tools, we first mapped and quantitatively evaluated the supply and demand of five ES types (water yield, soil conservation, carbon retention, food supply, and leisure and entertainment) in Hangzhou, China, based on land use, meteorology, soil, and socio-economic data. Then, we analyzed the matching characteristics between the supply and demand of these ESs and analyzed the complex trade-offs and synergy between the supply and demand of ESs and factors affecting ESs. The results of this analysis indicate that although the ES supply and demand of carbon retention tended to be out of balance (supply was less than demand), the supply and demand of the other four ES types (i.e., water yield, soil conservation, food supply, and leisure and entertainment) were in balance (supply exceeded demand). Finally, the spatial heterogeneity of the supply and demand of ESs in Hangzhou was significant, especially in urban areas in the northeast and mountainous areas in the southwest. The supply of ESs was based on trade-offs, whereas the demand of ESs was based on synergy. Our results further show that the supply and demand of ESs in the urban area in Hangzhou were out of balance, whereas the supply and demand of ESs in the western region were coordinated. Therefore, the linkage of ES flows between this urban area and the western region should be strengthened. This innovative study could provide useful information for regional land use planning and environmental protection.

This thesis is a supporting paper for a photographic exhibition that explores contemporary social and political issues in the country of Iran, through the depiction of a changing landscape. The work consists of photographs of the northern province of Gilan, Iran. As a critical body of work, the installation engages audiences to experience the changing environment and asks viewers to question the causes of the environmental changes in agricultural areas. A brief history of land use change in Iran during the White revolution is presented followed by a description of the current situation of farmlands in contemporary Iran. Goals for the project, methodology and issues of subjectivity are discussed. The shooting strategies, selection of the images, and presentation of the project is outlined. Finally, the essay discusses the project’s documentary relevance.

Abstract Quantifying the influences of land use/cover (LULC) change on hydrological processes is important for rational utilization of water resources. The objective of this study was to evaluate the impacts of spatiotemporal LULC change on hydrological components in a typical agricultural area located in the North China Plain at both basin and sub-basin scales. LULC change was quantified, and the Soil and Water Assessment Tool was optimized using parameters associated with LULC conditions. We concluded that the urban and forest areas increased by 25.57 and 10.56%, with the cropland area decreased by 36.76%. About half of the surface runoff (SURQ) in the basin was generated from the urban area, with the SURQ increased significantly in the upstream and downstream of the basin where overlapped with urbanized areas. The proportions of evapotranspiration generated by cropland and forest areas increased slightly (0.89 and 0.55%, respectively), especially in sub-basins where the conversion of cropland to forest was obvious. Urban, forest, and cropland were the main types that generated water yield (WYLD). The proportion of WYLD generated on the urban area increased by 9.55% and decreased in other areas, which may be related to the combined effects of urbanization and forest reduction.

The Way

When space is limited, there is often conflict over land use such as agriculture, nature conservation, housing, business and commercial enterprise. More knowledge is needed about the substance of such conflicts and the way the various uses are handled and spatially organised. Using empirical material collected in Hållnäs, Sweden, and Sandnes, Norway, between 2009 and 2012, this paper addresses the potential conflicts and synergies between the different uses of land, with agriculture as a reference point. In combining and comparing the results from Hållnäs and Sandnes, the way in which relations differ between them are also scrutinised. Through planning documents, interviews with officials in public authorities, active farmers, non-governmental organisations (NGO) and field visits, case-specific land uses are identified in the two areas. The conflicting and synergetic relations between agriculture and other ways the land is used are identified and illustrated by schematic models. The results indicate that agriculture is both in synergy and in conflict with other land uses. In the cases investigated in this study, the primary areas of conflict are between agriculture and biodiversity, between agriculture and cultural heritage, and between agriculture and climate-smart initiatives in terms of dense building structures.
