La falta de planeación en el manejo de las cuencas y subcuencas deriva en impactos ambientales negativos, afectando, no solo, los sistemas bióticos, sino también el bienestar de la población. En este sentido, esta investigación, presenta un diagnóstico y una propuesta de manejo integral de la subcuenca río Ciruelas. En la que se exponen las características tanto físico geográficas, como socio culturales que forman parte de esta subcuenca. Al conceptualizar a la subcuenca como un sistema, permite entender que existe una relación sociedad-naturaleza, la cual es vital para lograr equiparar o mitigar los efectos negativos en materia ambiental, social y económica que trae consigo el inadecuado manejo de los recursos. En el análisis de la subcuenca se parte del... |

En el presente estudio se realizó el análisis de las Unidades de Riego con aprovechamiento superficial en la Cuenca Lerma Chapala, México, a través de la georrefenciación y caracterización de la infraestructura hidroagrícola, padrón de usuarios y catastro, integrándolos en un Modelo de Sistema de Información Geográfica (SIG). Esto permitió conocer en forma precisa la información relevante de dichas Unidades. Se caracterizaron 1,364 unidades de riego con un total de 56,266 usuarios que detentan 114,975.26 hectáreas. La longitud de la red de conducción es de 2,435 km y la longitud de la red de drenaje es de 2,643 km, y 34,965 estructuras de control. La integración de las capas de información generadas en formato shape-file (*.shp) al Modelo de SIG de la... |

Climate change presents new challenges for the management of social-ecological systems and the ecosystem services they provide. Although the instrument of payments for ecosystem services (PES) has emerged as a promising tool to safeguard or enhance the provision of ecosystem services (ES), little attention has been paid to the potential role of PES in climate change adaptation. As an external stressor climate change has an impact on the social-ecological system in which PES takes place, including the various actors taking part in the PES scheme. Following a short description of the conceptual link between PES and adaptation to climate change, we provide practical insights into the relationship between PES and adaptation to climate change by presenting... |

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... |

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... |

The use conflicts are determined by the inadequate occupations of the soil, as it is the case of soil occupation inside of permanent preservation areas. This study aimed to determine the classes of the soil use and if there are conflicts inside of permanent preservation areas along the drainage network of the Água Fria Stream watershed, located in Bofete city - São Paulo, Brazil. It locates geographically between the coordinates: 48°09'30" to 48°18'30" longitude WGr., 22°58'30" to 23°04'30" latitude S, with an area of 15242.84 ha. The map of soil use was elaborated through the interpretation directly in the computer screen of satellite digital image. In the orbital data, the study area is inserted in the quadrant A, of image TM/Landsat - 5, orbit 220,... |

Le polder conchylicole de Bouin (Vendée) est le principal bassin français de production de naissains d’huîtres creuses issus d’écloseries. Depuis 2007, et malgré l’installation de dispositifs de traitement de l’eau, des anomalies dans les élevages voire des mortalités affectent la production des écloseries et nurseries du secteur, ainsi que celle de microalgues en grand volume d'une entreprise spécialisée. Les observations des professionnels orientent la recherche de la cause de ces mortalités sur les contaminants chimiques, notamment les pesticides utilisés par l'agriculture, dont les exploitations du polder agricole, qui jouxtent le polder conchylicole. Comme l'ont montré de nombreux travaux, certains de ces produits altèrent la qualité de l’eau de mer... |

The optimal size and location of an invasive species population depend upon spatially differentiated biological growth, economic costs, and damages. Although largely absent from most economic models, spatial considerations matter because the likelihood and magnitude of the invasion vary spatially and the threatened assets may be unevenly distributed across space. We map the current and future populations of an invasive species, Miconia calvescens, on Oahu, Hawaii, and the potential damages to water quantity, quality, and endangered-species habitat, and weigh these against treatment costs. We find that optimal densities vary from approximately 1% to 18% cover throughout the island. |
