| O presente trabalho objetivou avaliar o escoamento superficial da área que engloba os afluentes do Ribeirão Serragem no município de Tremembé, SP no vale do Paraíba do Sul, localizada na parte a montante da barragem da Fazenda Maristela, bem como mapear o uso do solo da mesma para subsidiar possíveis intervenções visando o uso sustentável dessa bacia. Foram empregadas técnicas de geoprocessamento com o uso de ferramentas do SPRING para a caracterização do uso e ocupação do solo, da caracterização física da bacia e para o cálculo da precipitação efetiva. Os resultados indicaram que a bacia do Ribeirão Serragem apresenta um bom estado de conservação, levando em consideração que ocorre o predomínio de florestas em todas as classes de APP com maior predomínio... |

| O presente trabalho objetivou determinar os Hidrogramas de Precipitações Efetivas Máximas a partir do método do Hidrograma Unitário (HU) da bacia do Ribeirão Serragem no município de Tremembé, SP no vale do Paraíba do Sul, localizada na parte a montante da barragem da Fazenda Maristela. Foram empregadas técnicas de geoprocessamento com o uso de ferramentas do SPRING para a caracterização do uso e ocupação do solo e caracterização física da bacia para o cálculo da Precipitação efetiva (Pe) resultante de chuvas máximas sobre a bacia simuladas para 2, 5, 10, 15, 20, 25, 50, 100 e 200 anos. O cálculo da Pe foi realizado pelo método do Curva Número (CN). Os resultados indicaram que a bacia do Ribeirão Serragem apresenta um bom estado de conservação, levando em... |

| Se realizó un estudio de mercado de los servicios ambientales hidrológicos (SAH) en la cuenca de Tapalpa, Jalisco, México, cuya superficie es de 21,000 ha, donde el 44% es de uso forestal. Para determinar la oferta hidrológica se utilizó el modelo hidrológico SWAT (soil and water assesment tool, herramienta de valoración de suelo y agua) que presentó un buen ajuste (R2 = 0.85) al ser calibrado con la producción de agua en una de las cinco subcuencas que integran el área de estudio. El análisis de demanda indica que existe un superávit del recurso hídrico (19,792,015 m3/año), ya que solamente se aprovecha el 54% (23,171,885 m3/ha) de la oferta total (42,963,900 m3/ha). De ésta, el 93% seutiliza en el sector agrícola, principalmente en la producción de... |

| As natural areas, agricultural lands, and open spaces continue to be developed at unprecedented rates, it is important for land conservation professionals to understand the individuals who might play a role in permanently protecting these lands and their ecological services. Many factors have been shown to influence land protection decisions among private owners, including land-use activities, demographic characteristics, and environmental intention and behavior. With the hypothesis that individuals already involved in land conservation programs would be candidates for permanent protection, we set out to model conservation easement decisions within a group of participants in southern Indiana’s Classified Forest and Wildlands Program (ICFWP).... |

| Reindeer herding is an emblematic livelihood for Northern Finland, culturally important for local people and valuable in tourism marketing. We examine the livelihood resilience of Finnish reindeer herding by narrowing the focus of general resilience on social-ecological systems (SESs) to a specific livelihood while also acknowledging wider contexts in which reindeer herding is embedded. The questions for specified resilience can be combined with the applied DPSIR approach (Drivers; Pressures: resilience to what; State: resilience of what; Impacts: resilience for whom; Responses: resilience by whom and how). This paper is based on a synthesis of the authors’ extensive anthropological fieldwork on reindeer herding and other land uses in Northern... |

| The ability to incorporate and manage the different drivers of land-use change in a modeling process is one of the key challenges because they are complex and are both quantitative and qualitative in nature. This paper uses Bayesian belief networks (BBN) to incorporate characteristics of land managers in the modeling process and to enhance our understanding of land-use change based on the limited and disparate sources of information. One of the two models based on spatial data represented land managers in the form of a quantitative variable, the area of individual holdings, whereas the other model included qualitative data from a survey of land managers. Random samples from the spatial data provided evidence of the relationship between the different... |

| Using the systems approach framework (SAF), a coupled model suite was developed for simulating land-use decision making in response to nutrient abatement costs and water and nutrient fluxes in the hydrological network of the Scheldt River, and nutrient fluxes in the estuary and adjacent coastal sea. The purpose was to assess the efficiency of different long-term water quality improvement measures in current and future climate and societal settings, targeting nitrogen (N) load reduction. The spatial-dynamic model suite consists of two dynamically linked modules: PCRaster is used for the drainage network and is combined with ExtendSim modules for farming decision making and estuarine N dispersal. Model predictions of annual mean flow and total N... |

| Although it has been repeatedly demonstrated that urbanization has negative environmental consequences, the conversion of land to urban use is increasing worldwide and is not likely to abate. We tested the hypothesis that different urban typologies, i.e., distributions of human population and infrastructure, differentially influence the water quality and ecological functionality of emergent marsh wetlands in New York State's Hudson River Valley. Wetlands were studied in two watersheds, defined as landscapes bounded by ridge lines, containing traditional small-town development and two watersheds containing suburban typologies. Land cover attributes were evaluated by analyzing ground-truthed, orthophotoquad data with a GIS. Water quality, the cover and... |

| Food supply and food distribution have been and are important issues in the global political arena. The recent emergence of biofuel policies has increased the influence of the policy arena on agricultural production. In this paper we show the regional impact of changes in the European Common Agricultural Policy and biofuel policy. Shifting trade patterns, changes in agricultural production, and expansion of agricultural area or intensification of agriculture result in changes in land use and land use emissions. Higher prices for agricultural crops on the world market together with changing production raise agricultural income. Brazil is the region the most affected. The results show that arrangements or policies will be needed to avoid negative impacts in... |

| The southern Piedmont of the southeastern United States epitomizes the complex and seemingly intractable problems and hard decisions that result from uncontrolled urban and suburban sprawl. Here we consider three recurrent themes in complicated problems involving complex systems: (1) scale dependencies and cross-scale, often nonlinear relationships; (2) resilience, in particular the potential for complex systems to move to alternate stable states with decreased ecological and/or economic value; and (3) uncertainty in the ability to understand and predict outcomes, perhaps particularly those that occur as a result of human impacts. We consider these issues in the context of landscape-level decision making, using as an example water resources and lotic... |
