Because of the inevitable depletion of fossil fuels and the corresponding release of carbon to the environment, the global energy future is complex. Some of the consequences may be politically and economically disruptive, and expensive to remedy. For the next several centuries, fuel requirements will increase with population, land use, and ecosystem degradation. Current or projected levels of aggregated energy resource use will not sustain civilization as we know it beyond a few more generations. At the same time, issues of energy security, reliability, sustainability, recoverability, and safety need attention. We supply a top-down, qualitative model—the surety model—to balance expenditures of limited resources...
The main properties of a phytoclimatic model are explained. It is a technique for theoretic simulation but a field work verification is essential. The methodology involves the transformation of a territory's general phytoclimate data into particular phytoclimate estimates. We are dealing with a simple mathematical climate-soil-relief-vegetation model offering the possibility of predicting changes in vegetation liable to occur at any point in the Iberian peninsula's territory, when the climate data values of a site change as compared with data currently estimated. It consequently enables both alterations and sensitivity of potential plant communities to possible climate changes to be detected and predicted at a certain...
This paper presents the links between the climate model IMAGE 2 and the economic model WORLD SCAN, which are set up to obtain an integrated scenario instrument for comprehensive and consistent climate-economy scenarios. The links are made with respect to energy (in WORLD SCAN) and agriculture (in IMAGE 2), thus providing a consistent linkage with feedbacks running both ways.

In 2015, the total amount of water withdrawn for power generation uses in Florida was estimated at 9,859 million gallons per day (Mgal/d). Withdrawals include water used for once-through cooling, cooling pond augmentation, boiler make-up, and domestic uses at power facilities. Saline water accounted for 9,425 Mgal/d of the water withdrawn for power generation, while fresh water accounted for 434 Mgal/d of the water withdrawn for this category. Of the saline water, 9,396 Mgal/d was withdrawn from surface water sources and 29 Mgal/d was withdrawn from groundwater sources. Of the fresh water, 406 Mgal/d was withdrawn from surface water sources and 28 Mgal/d was withdrawn from groundwater sources. Pasco County accounted...
This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs....

The SARP Flow Alteration Assessment provides a regional characterization of the distribution and risk of flow regime impairment of streams and rivers by anthropogenic sources at the NHD+ segment scale. This map illustrates the cumulative risk of flow alteration (RFA) from surface water use for irrigation in Texas and Oklahoma.  Water use is based on state permits for surface water withdrawals and returns.  The risk is based on the volume of water used monthly in the drainage area relative to the monthly volume of flow.  Risk of Flow Alteration categories:  ZERO     - 0% mean monthly flow depletion,  LOW      - > 0-10%,  MEDIUM - > 10-20%,  HIGH      - >20-100%, and  PROVISIONAL...
The contribution of households to CO 2 production is still increasing. To alter patterns of energy consumption for example with respect to commuter traffic, using the freezer, and warming the house, changing life styles related to domestic energy consumption is considered. In our study, we have operationalized life style as means-end chains, that link perceived benefits of a particular behavior to basic values that people pursue. In this paper, preliminary results are presented of the study that is aimed at empirically establishing the feasibility of the concept of life style in relation to domestic energy consumption.

Total water demand (gallons per day per acre) summarized to 12-digit HUC watersheds was derived from EnviroAtlas agricultural, domestic, industrial, and thermoelectric water demand datasets.Information about the original EPA data is as follows:Agricultural water demand:The EnviroAtlas national water demand metric provides insight into the amount of water currently used for agricultural irrigation in the contiguous United States. The values are based on 2005 irrigation water use; combined 2010 crop, 2006 land use, and 2001 remotely sensed irrigation location estimates; and have been summarized by watershed or 12-digit hydrologic unit code (HUC). Agricultural irrigation water use, as defined in this case, meets a...

Thuis empirical note provides a disaggregated analysis of the causal relationship between fossil fuel consumption and real gross domestic product (GDP) in the US using annual data from 1949 to 2006. The Toda-Yamamoto long-run causality tests reveal the absence of Granger-causality between coal consumption and real GDP; positive undirectional causality from real GDP to natural gas consumption; and positive undirectional causality from petroleum consumption to real GDP.

In 2015, the total amount of water withdrawn for agricultural irrigation uses in Florida was estimated at 2,089 million gallons per day (Mgal/d). Withdrawals include water used for crop irrigation, freeze protection, livestock needs, and fish farming (aquaculture). Fresh surface water accounted for 1,078 Mgal/d of the fresh water withdrawn and1,011 Mgal/d was withdrawn from fresh groundwater sources. Palm Beach County accounted for the largest amount of fresh surface water withdrawn (513 Mgal/d), followed by Hendry County (257 Mgal/d), while Hendry County accounted for the largest amount of fresh groundwater withdrawn (123 Mgal/d) followed by Collier County (97 Mgal/d). No saline water was withdrawn for this category...

Florida’s water resources have been managed by five water management districts since 1972. These five regional water management districts are the Northwest Florida, St Johns River, South Florida, Southwest Florida, and the Suwannee River. In 2015, the Southwest Florida Water Management District accounted for the largest amount of saline water withdrawn (5,135 Mgal/d) and the South Florida Water Management District accounted for the largest amount of fresh water withdrawn (2,792 Mgal/d). The South Florida Water Management District accounted for the largest amount of water withdrawn for public supply (1,118 Mgal/d), agricultural irrigation (1,380 Mgal/d), and recreation-landscape irrigation (263 Mgal/d), while the...

This dataset identifies the number of individually-owned domestic wells, and the number of households relying upon domestic water supply in the state of California. The number of wells and households are summarized for each Public Land Survey System (PLSS) section. The well locations were determined from more than 635,000 scanned well-completion reports (WCRs) provided by the California Department of Water Resources in 2011. This is only a partial sample of the total number of WCRs (estimated at 1 to 2 million in total). The number of domestic wells was estimated based upon a spatially distributed and randomized survey that determined the Township Ratio (TR) for each township in the state (4,692 in total). Each...
