| The importance of corn production to the midwestern United States cannot be overestimated. However, high production requires high nitrogen fertilization, which carries costs to environmental services such as water quality. Therefore, a trade-off exists between the production of corn yield and water quality. We used the Groundwater Vulnerability Assessment for Shallow depths and Crop Environment Resource Synthesis-Maize models to investigate the nature of this trade-off while testing the Simple Analytic Framework trade-offs featured in this Special Feature. First, we estimated the current levels of yield and water quality production in northeastern Iowa and southern Minnesota at the 1-square-kilometer, county, and regional scales. We then constructed an... |

| Among the strategies to promote sustainable tropical forest development around the world, the Federal Extractive Reserve System of Brazil is widely cited as an exemplary model. It is designed to protect rubber tapper communities, their forests, and their livelihoods while preventing deforestation and conserving biodiversity. In response to changing markets and policies, rubber tappers in the Chico Mendes Extractive Reserve have recently diversified production to include market agriculture and cattle production, precipitating deforestation in the reserve, with the implication of increased ecological degradation compared to the extraction of nontimber forest products (NTFPs). Our remote sensing and forest inventory analyses yield different insights about the... |

| A computer simulation model, the Regional Simulator (RSim), was constructed to project how land-use changes affect the quality of water, air, noise, and habitat of species of special concern. RSim was designed to simulate these environmental impacts for five counties in Georgia that surround and include Fort Benning. The model combines existing data and modeling approaches to simulate the effects of land-cover changes on: nutrient export by hydrological unit; peak 8-h average ozone concentrations; noise caused by small arms and blasts; and habitat changes for the rare Red-cockaded Woodpecker (Picoides borealis) and gopher tortoise (Gopherus polyphemus). The model also includes submodules for urban growth, new urbanization influenced by existing roads,... |

| This paper discusses opportunities for alternative collaborative approaches for social-ecological research in general and, in this context, for modeling land-use/land-cover change. In this field, the rate of progress in academic research is steady but perhaps not as rapid or efficient as might be possible with alternative organizational frameworks. The convergence of four phenomena provides new opportunities for cross-organizational collaboration: (1) collaborative principles related to "open source" (OS) software development, (2) the emerging area of "open content" (OC) licensing, (3) the World Wide Web as a platform for scientific communication, and (4) the traditional concept of peer review. Although private individuals, government organizations, and... |

| This study assesses the persistence and change of traditional land use patterns and ecological knowledge in response to expanded commercialization of tea (Camellia sinensis var. assamica (L.) Kuntze Theaceae in an indigenous Akha (Hani) community in the midlevel montane forests of southwest Yunnan, China. Surveys were conducted in 2005 and 2008, over a period corresponding to a regional tea market boom and bust cycle, to compare the valuation smallholders attribute to land use types and to determine the role that value systems play in shaping environmental behavior and knowledge. At the community level, increased market integration of tea agroforests is associated with reconfiguration of land use, intensified management, reorganization of labor structures,... |

| Global change is the net effect of individual and interactive effects of changes in land use, atmospheric composition, biological diversity, and climate. A synthesis of the past six years' activities of the Global Change and Terrestrial Ecosystems project of the IGBP (International Geosphere-Biosphere Programme) deals with global change effects as ecosystem responses and living with global change. Ecosystem responses are considered in terms of changes in function and vegetation composition/structure. Field experiments of elevated CO2 effects on aboveground biomass show, on average, a positive effect on biomass, ranging from -20% to +80%. Some early predictions of CO2 effects (C3 vs. C4 plants, N-fixers, C:N in litter) are not generally supported, and it... |

| The interdisciplinary framework known as resilience theory used by ecologists, social scientists, as well as policy makers, is primarily concerned with the sources of transformation and stability in complex socioecological systems. The laboratory of the long and diverse archaeological record is uniquely suited to testing some of the implications of this theoretical perspective. In this paper, we consider the history of land use and landscape change across the transition from foraging to agricultural subsistence economies in the Middle Chevelon Creek region of northern Arizona. Through this discussion, we highlight the potential roles of diversity and flexibility at multiple spatial and temporal scales in the resilience of human land use practices from the... |

| In the Río de la Plata grasslands (RPG) biogeographical region of South America, agricultural activities have undergone important changes during the last 15–18 years because of technological improvements and new national and international market conditions. We characterized changes in the landscape structure between 1985–1989 and 2002–2004 for eight pilot areas distributed across the main regional environmental gradients. These areas incorporated approximately 35% of the 7.5 × 105 km² of the system. Our approach involved the generation of land-use and land cover maps, the analysis of landscape metrics, and the computation of annual transition probabilities between land cover types. All of the... |

| Assessments of ecosystem services (ES), that aim at informing decisions on land management, are increasing in number around the globe. Despite selected success stories, evidence for ES information being used in decision making is weak, partly because ES assessments are found to fall short in targeting information needs by decision makers. To improve their applicability in practice, we compared existing concepts of ES assessments with focus on informing land use decisions and identified opportunities for enhancing the relevance of ES assessments for decision making. In a process of codesign, building on experience of four projects in Brazil, China, Madagascar, and Vietnam, we developed a step-wise approach for better targeting ES assessments toward... |

| Ex ante impact assessment can help in structuring the analysis of human-environment interactions thereby supporting land use decision making for sustainable development. The contributions to this special feature focus on some of the challenges of making land use impact assessment operational for policy making. A total of nine papers deal with the needs and uses of assessment tools for policy making at the European level, with the value-based influence in scenario development, and with ex ante impact assessment studies in different contexts, spatial systems, and for different purposes and user groups. The concept of landscape multifunctionality was implicitly or explicitly employed as an integrating entity between socioeconomic and biogeophysical features... |

| The goal of the present work is to synthesize the process of collective construction developed to protect the high-altitude wetlands of the Blanco River basin, located in the Andes Mountains, Province of Mendoza. The participatory process arose out of an initiative of basin residents and users, and was conducted by the Integrative Committee for Creation of Potrerillos Municipal Environmental Protected Area (MEPA), composed of civil society organizations, government agencies and scientific institutions. The major pressures affecting the wetlands, identified through participatory assessment of the socio-ecosystem are: water pollution, reduction and total loss of habitat, stoppage of groundwater flows, artificial drainage, poldering of the meadow, and... |

| ABSTRACT Changes in the Brazilian Forest Code (BFC) have soften the criteria for recovery and conservation of permanent preservation areas (PPAs), enhancing processes related to surface runoff. The aim of this study is to understand the effects of changes in PPA classification criteria established by BFC of 2012 to the detriment of BFC from 1965 considering the surface runoff response in the basin draining the upper Marrecas River valley in the flow peaks. The HEC–HMS model was used to simulate flow peaks considering three land-use scenarios, representative of the current use, adapting it to PPAs fitted to the BFC of 1965 and 2012 and seven precipitation return periods. In the proposed scenarios, the use of BFC of 2012, to the detriment of that from 1965,... |

| ABSTRACT: Since colonial times, Brazilian land use has been made under an extractivist model at the expense of deforestation, increasing soil and vegetation depletion, stream siltation, as well as loss of biodiversity. An ecological-economic zoning (EEZ) has been taken as feasible alternative to guide public policies aimed at city land-use planning. This study focused on designing an EZZ for the city of Altinópolis, in São Paulo state (Brazil), by means of geographical information systems (GIS). Information and maps delineated six land-use areas, in which 30% covered areas under environmental protection, 45% over areas with groundwater recharge potential, which should be intended to restoration. Furthermore, around 70% of the territory show potential to be... |

| Nearly forty percent of mankind depend in one way or another on mountain ecosystems. Local ecosystem services are slope stability, water yield, agricultural products or recreational value. Continental scale influences include drinking water supply, ground water recharging, irrigation water, hydroelectric power, flood control, traffic routes etc. In this paper I review evidence of alpine ecosystem responses to global change. It is emphasized that soil conservation is the centerpiece of any consideration of sustainable land use in alpine terrain. Complete vegetation cover of high biological diversity is essential to protect soils and secure `ecosystem services' in upland systems. It is illustrated that this is not necessarily in conflict with land use and... |
