Abstract The incidence of tick-borne diseases has increased in recent decades and accounts for the majority of vector-borne disease cases in temperate areas of Europe, North America, and Asia. This emergence has been attributed to multiple and interactive drivers including changes in climate, land use, abundance of key hosts, and people’s behaviors affecting the probability of human exposure to infected ticks. In this forum paper, we focus on how land use changes have shaped the eco-epidemiology of Ixodes scapularis-borne pathogens, in particular the Lyme disease spirochete Borrelia burgdorferi sensu stricto in the eastern United States. We use this as a model system, addressing other tick-borne disease systems as needed to illustrate patterns or processes. We first examine how land use interacts with abiotic conditions (microclimate) and biotic factors (e.g., host community composition) to influence the enzootic hazard, measured as the density of host-seeking I. scapularis nymphs infected with B. burgdorferi s.s. We then review the evidence of how specific landscape configuration, in particular forest fragmentation, influences the enzootic hazard and disease risk across spatial scales and urbanization levels. We emphasize the need for a dynamic understanding of landscapes based on tick and pathogen host movement and habitat use in relation to human resource provisioning. We propose a coupled natural-human systems framework for tick-borne diseases that accounts for the multiple interactions, nonlinearities and feedbacks in the system and conclude with a call for standardization of methodology and terminology to help integrate studies conducted at multiple scales.

This paper is an outcome of research concerning spatial differences in forms and coverage of land use in the Progo River Basin. At present the watershed is facing the problem of land use changes from agricultural to non-agriultural ones, leading to the situation of decreasing staple foods. This research is aimed at studying regional variation in the potentials of the research area of the production of staple foods according toland use forms and coverage. Informastion on land use forms and coverage are obtained from the statistical record issued by the Statistical Office of Central Java province and Yogyakarta Speial Provine. As the productivity data on every land use forms are not readily available, the assement on the regional potential is executed on the basis of land use intensity and its apability to produce staple foods. The research reveals that the greatest portion (59 %) of lands in 54 subdistrict in the watershed are highly potential for staple foods production and the rest (41 %) are not potential to moderately potential for staple foods production purpose. The potential for staple foods production in the upper part of the Progo river basin are higher than that in lower part ones. The presence on irrigated land is not always highly potential for staple food production. Although the availability of irrigation water is strongly decisive factor for food prodution (r = 0.661 significant at 99.99 percent), but the presence of built up areas are strongly dictated the potential for food production (r = -0,787 significant at 99.99 percent). The research further shows that the higher the potential for food production, the higher population size (r = 0.791) significant at 99.99 percent). In general it can be concluded that 1) the potentials for food production are determined by the available of irrigation water and the size of the built areas, and 2) the number of population is dictated by the presence of water and potentials for food production.

Abstract Applying a Regional Integrated Vulnerability Assessment (RIVAS), this study aims to identify local farming system characteristics, their climate change vulnerability and how they are affected by current land use changes. Results show that the assessed farming systems' multifunctionality is essential to rural livelihoods whilst sustaining crop and tree diversity. While dry season crop diversity drives household's sufficiency and capacity to respond to crop failure, medium-low productivity in more than a third of the assessed systems, and soil degradation in cereal fields lessen adaptive capacity. For their contribution to climate resilience diverse and perennial cropping regimes should be promoted and maintained.

The Past

The small Sanjiang plain is one of the most important commodity grain production bases and the largest fresh water wetland in China. Due to the rapid expansion of agricultural activities in the past 30 years, the contradiction between economic development and the loss of ecosystem services has become an issue of increasing concern in the area. In this study, we analysed land use changes and the loss of ecosystem services value caused by these changes. We found that cropland sprawl was predominant and occurred in forest, wetland, and grassland areas in the small Sanjiang plain from 1980 to 2010. Using a model to evaluate ecosystem services value, we calculated that the decreased values of ecosystem services were 169.88 × 108Yuan from 1980 to 2000 and 120.00 × 108Yuan from 2000 to 2010. All of the ecosystem services were diminished from 1980 to 2010 except for food production. Therefore, the loss of ecosystem services value should be considered by the policymakers of land use and development.

Land use changes and land intensification has played a more and more important role in food production. The environment has been influenced by it greatly. Land use data were derived from several sources: aerial photographs, current land use maps, Second National Soil Survey (SNSS) map, and fieldwork. The aerial photographs, 1:50,000 for both 1980 and 2006 were obtained from the Department of Surveys and Mapping (DSM). Bulk soil samples were collected at 79 sites across Quzhou district. Samples were collected again at the same locations in 2000 and 2006. To compare the soil data of 2006, 2000 and 1980, latitude and longitude of the sampling locations were recorded using the Global Position System at the time of soil collection. The samples site selection was done on behalf of the Second National Soil Survey. A great change had taken place in land use and land use intensification. The changes, which have converted natural landscapes into the use for human, have made a large proportion of the Quhzou’s landscape change greatly.

Ghg Savings

Limited land is available globally to grow crops for food and fuel. There are direct and indirect pressures on forests and other lands to be converted from growing food for feedstock to be used for biofuel production. The balance of evidence indicates there will probably be sufficient appropriate land available to meet demands for both food and fuel, but this needs to be confirmed before global supply of biofuel is allowed to increase significantly. There is a future for a sustainable biofuels industry, but feedstock production must avoid encroaching on agricultural land that would otherwise be used for food production. And while advanced technologies offer significant potential for higher greenhouse gas (GHG) savings through biofuels, these will be offset if feedstock production uses existing agricultural land and prevents land-use change. GHG savings can be achieved by using feedstock grown mainly on marginal land or that does not use land, such as wastes and residues. To ensure that biofuels deliver net GHG benefits, governments should amend, but not abandon, their biofuel policies in recognition of the dangers from indirect effects of land-use changes. Large areas of uncertainty remain in the overall impacts and benefits of biofuels. International action is needed in order to improve data, models and controls, and to understand and to manage effects.
