| Most studies developed about agrarian societies usually refer to rural space as private space. Nevertheless the concept of “rural property” can raise a host of distinct interpretations, especially when one brings into analysis the interaction among populations and natural resources. This present piece of work aims at going deeper into the establishment of the environmental typology built by family-related agriculturists of two rural communities from Turmalina, MG, and the diversification of use given to each of these environments by their inhabitants. Arrangements on the use and the management of collective resources may come to contributing with the formatting of new projects which seek to promoting the country’s environmental planning, plus allowing for... |

| According to the relevant data about the land resources and population in Liaocheng City from 1999 to 2008, by using the research method of bearing capacity of natural resources, the thesis analyzes the relationship between natural resources and dynamic change of population in Liaocheng City. The results show that the farmland tends to diminish on the whole, and forests, garden land, urban-rural settlements and land for enterprises and mining increase slowly. Based on the analysis of the dynamic relationship between land resources and population, we conclude that the land resources still can bear the current population in Liaocheng City, but the population development inflict critical pressure on the forest resources and water resources. |

| This paper examines multi-factor productivity trends in the U.S. petroleum, coal, copper and logging industries since 1970. Measures of multi-factor productivity growth are negative for all four industries during the 1970's. At the time this led to fears that stocks of natural resources were being exhausted, and this might hinder future economic growth. However in retrospect the 1970's look like an exceptional period, rather than marking a change in long run productivity trends. The decline in measured multi-factor productivity in that decade appear to be explained by a number of special factors that generally have a transitory rather than a permanent effect on productivity growth. For example, the rise in natural resource prices encouraged the entry of... |

| The Rio Grande has headwaters in Colorado, flows through New Mexico, and serves as the United States.–Mexico border in Texas, emptying into the Gulf of Mexico. Snow melt in Colorado and northern New Mexico constitutes the water river supply for New Mexico and the El Paso region, whereas summer monsoonal flow from the Rio Conchos in Mexico and tributaries, including the Pecos River, provides the Rio Grande flow for southern Texas. The region is mostly semiarid with frequent long-term drought periods but is also characterized by a substantial irrigated agriculture sector and a rapidly growing population. International treaties and interstate compacts provide the rules for allocation of Rio Grande waters between the United States and Mexico and among... |

| This paper traces the evolution of space-derived remote sensing data and data products from their initial dissemination to their impact on public policy related to climate change. We focus on the examples of renewable energy, public health, and ecosystem assessment. Our approach differs from previous studies that have characterized the value of data in terms of the fundamental scientific phenomena they describe. In our research we have sought to identify contributions of space-derived earth science in "making a difference" beyond scientific understanding, thereby providing at least a partial answer to questions about the utility of research posed by Congress, the Office of Management and Budget, managers at the National Aeronautics and Space... |

| Individual fishery quotas (IFQs) are an increasingly prevalent form of fishery management around the world, with more than 170 species currently managed with IFQs. Yet, because of the difficulties in matching quota holdings with catches, many argue that IFQs are not appropriate for multispecies fisheries. Using on-the-ground-experience with multispecies IFQ fisheries in Iceland, New Zealand, Australia, and Canada, we assess the design and use of catch-quota balancing mechanisms. Our methodology includes a mix of interviews with fishery managers, industry representatives, and brokers, literature review, and data analysis. We find that a combination of incentives and limits on use rates for the mechanisms provide sufficient flexibility to the quota owner... |
