La explicación del riesgo de sequía en la Geografía escolar. Una exploración desde los manuales escolares de Ciencias Sociales (Educación Primaria)
2021
espanolEn la region mediterranea uno de los principales riesgos naturales son las sequias. Este fenomeno se ha agravado en las ultimas decadas debido al incremento de la vulnerabilidad asociadas a actividades humanas y, segun los escenarios futuros de cambio climatico, se preve que aumente la peligrosidad (mayor intensidad y frecuencia de los periodos secos). El objetivo de este trabajo es llevar a cabo un analisis de como se explica el riesgo de sequia en los manuales escolares de Ciencias Sociales (3er ciclo de Educacion Primaria) en la Comunidad Valenciana (Espana). A partir de la consulta de estos recursos (las 5 editoriales mas utilizadas), los resultados obtenidos indican que esta tem…
Constraining Uncertainty in Projected Gross Primary Production With Machine Learning
2020
The terrestrial biosphere is currently slowing down global warming by absorbing about 30% of human emissions of carbon dioxide (CO2). The largest flux of the terrestrial carbon uptake is gross primary production (GPP) defined as the production of carbohydrates by photosynthesis. Elevated atmospheric CO2 concentration is expected to increase GPP (“CO2 fertilization effect”). However, Earth system models (ESMs) exhibit a large range in simulated GPP projections. In this study, we combine an existing emergent constraint on CO2 fertilization with a machine learning approach to constrain the spatial variations of multimodel GPP projections. In a first step, we use observed changes in the CO2 sea…
Imagining a “post-carbon” future? Climate change as represented by media and film industries
2020
This study explores current trends in representing and communicating climate change by media industries. It reviews the current literature on mainstream media narratives of climate change focusing on their naturalization of progress and their techno-optimism (e.g., as regards geoengineering). It provides insight on how the media industry’s commercial agenda is linked to the types of disseminated messages and dominant imaginaries. It compares respective codes inherent in news media and film/fictional representations of climate change on representative examples. It traces the evolution of disaster/dystopian genres that involve climate issues. It discusses the implications from such a comparat…
A Soil Water Assessment Tool (SWAT) Modeling Approach to Prioritize Soil Conservation Management in River Basin Critical Areas Coupled With Future Cl…
2021
About 44% of the Indian landmass experiences the adverse impact of land degradation. This loss of sediments caused by soil erosion reduces the water quality of local water bodies and decreases agricultural land productivity. Therefore, decision-makers must formulate policies and management practices for sustainable management of basins that are cost-effective and environment friendly. Application of the best management practices (BMPs) to properly manage river basins is difficult and time-consuming. Its implication under various climate change scenarios makes it more complicated but necessary to achieve sustainable development. In this study, the soil and water assessment tool (SWAT) model…
Constant, cycling, hot and cold thermal environments: strong effects on mean viability but not on genetic estimates
2012
It has frequently been suggested that trait heritabilities are environmentally sensitive, and there are genetic trade-offs between tolerating different environments such as hot and cold or constant and fluctuating temperatures. Future climate predictions suggest an increase in both temperatures and their fluctuations. How species will respond to these changes is uncertain, particularly as there is a lack of studies which compare genetic performances in constant vs. fluctuating environments. In this study, we used a nested full-sib/half-sib breeding design to examine how the genetic variances and heritabilities of egg-to-adult viability differ at high and low temperatures with and without da…
Organizational climate and climate strength in UK hospitals
2008
In recent years, researchers have paid increasing attention to the idea of “climate strength” – the level of agreement about climate within a work group or organization. However, at present the literature is unclear about the extent to which climate strength is a positive attribute, and is concerned predominantly with small teams or organizational units. This paper considers three theoretical perspectives of climate strength, and extends these to the organizational level. These three roles of climate strength are then tested in 56 hospitals in the United Kingdom. Positive relationships were discovered between two of three climate dimensions (Quality and Integration) and expert ratings of or…
Late frost damage risk for viticulture under future climate conditions: a case study for the Luxembourgish winegrowing region
2013
Background and Aims Late frosts are a significant risk to grape production in frost-prone viticultural regions. Increasing air temperature because of climate change is likely to advance grape budburst and last frost events in spring. So far, it is unclear whether one trend will be more pronounced than the other, and hence, whether the risk of late frost damage will increase or decrease. The aim of this work was to investigate the future frost risk in the Luxembourgish winegrowing region by assessing the effect of simulated future climate conditions on the timing of budburst and last frost date. Methods and Results Late frost risk was assessed by combining: (i) a phenological model for budbu…
