CLIMATIC NEEDS OF AUTUMN BARLEY AND CLIMATE CHANGE

Journal Articles & Books
Diciembre, 2009

Munkánkban összehasonlító vizsgálatokat végeztünk az őszi árpa fejlődési szakasza¬inak klimatikus igényeiről. A becsült meteorológiai jellemzők átlagosan nem mutatnak nagy változást a közeljövőre – jóllehet a század végére már igen –, de eloszlásuk alakulása a mezőgazdaságban komoly következményekkel járhat. A növény szempontjából azonban az éves és havi átlaghőmérséklet, illetve csapadékösszegek elemzése helyett sokkal több információhoz juthatunk, ha a növény fejlődési szakaszait külön-külön vizsgáljuk.

Farmers' (local and colonists) perceptions of environmental changes in the forest frontier of the upper Amazon, Peru

Journal Articles & Books
Diciembre, 2014
Perú

Amazon ecosystem degradation profoundly impacts life supporting processes of global importance such as climate regulation, as well as local conditions for livelihoods. In Peru's highland jungle, an expanding deforestation front of forest conversion to agriculture has vastly transformed the landscape. Small–scale farming, the main driver of forest degradation, and consequently household natural resource management affect ecosystem functionality. To investigate farmers' attitudes and priorities to services provided by the ecosystems (ES) we interviewed 51 farmers, both local and colonists.

Hydrological and land use determinants of Eucalyptus camaldulensis occurrence in floodplain wetlands

Journal Articles & Books
Diciembre, 2014
Australia

Hydrological and land use changes can affect species in human altered landscapes. Typically the impacts of hydrological and land use changes are examined separately, with hydrological determinants used to explain the distribution of species in water dependent and aquatic habitats and land use factors used to examine terrestrial species. However, given the connectedness of aquatic and terrestrial habitats, stressors originating in one domain may be important in the other.

Rangeland responses to pastoralists’ grazing management on a Tibetan steppe grassland, Qinghai Province, China

China
Asia

Livestock grazing is the principal land use in arid central Asia, and range degradation is considered a serious problem within much of the high-elevation region of western China termed the Qinghai-Tibetan Plateau (QTP). Rangeland degradation on the QTP is variously attributed to poor livestock management, historical-cultural factors, changing land tenure arrangements or socioeconomic systems, climate change, and damage from small mammals. Few studies have examined currently managed pastures using detailed data capable of isolating fine-scale livestock–vegetation interactions.

First assessment of effects of global change on threatened spiders: Potential impacts on Dolomedes plantarius (Clerck) and its conservation plans

Journal Articles & Books
Diciembre, 2013
Francia

Our view of the future of biodiversity remains limited to a restricted number of taxa, and some taxa, such as spiders, have been largely omitted. Here we provide the first assessment of effects of global change on threatened spiders using a red-listed vulnerable spider, Dolomedes plantarius (Clerck, 1757) as an example. We aim at applying this assessment to assist two conservation actions for this species, including a translocation program. We compiled all the available data on D.

Climate and vegetation hierarchically structure patterns of songbird distribution in the Canadian boreal region

Journal Articles & Books
Diciembre, 2014

Environmental factors controlling the distribution and abundance of boreal avifauna are not fully understood, limiting our ability to predict the consequences of a changing climate and industrial development activities underway. We used a compilation of avian point‐count data, collected over 1990–2008 from nearly 36 000 locations, to model the abundance of individual forest songbird species within the Canadian boreal forest.

Water management and multiple land use: the dutch approach: competing and complementary functions in water management

Journal Articles & Books
Diciembre, 2011
Países Bajos

Climate change, food crises and deterioration of the environment create immense challenges in water management. In the Netherlands land subsidence, high population density and intensity of land use aggravate these problems. Increased awareness of these problems and civil society's participation in the discussions complicate these challenges. The Netherlands' Government Service for Land and Water Management (DLG), an organisation specialising in integrated land development, has tackled these problems at a regional/local scale.

Numerical assessments of the impacts of climate change on regional groundwater systems in a paddy-dominated alluvial fan

Japón

Quantitative assessment of the impacts of climate change on groundwater levels is important for sustainable groundwater use. This study examined the Tedori River alluvial fan in Ishikawa Prefecture, Japan, where paddy fields occupy 45 % of the total area. A regional groundwater flow model simulated future groundwater levels in response to 38 climate change projections generated for each of three GCMs, using three GHG emission scenarios with the ELPIS-JP datasets.

Scenario analysis for regional decision-making on sustainable multifunctional land uses

Journal Articles & Books
Diciembre, 2014

Land-use patterns are influenced by both top-down and bottom-up (local) factors, with their interactions varying in both space and time. This provides a major challenge to decision-making for sustainable multifunctional landscapes. A cross-scale scenario structure has been developed to integrate top-down and bottom-up context based upon the familiar IPCC Special Report on Emission Scenarios framework.

influence of climate change on the soil organic carbon content in Italy from 1961 to 2008

Journal Articles & Books
Diciembre, 2011
Italia

Soils are the biggest carbon store in the world (1500Gt, e.g. 1.5×10²¹g). The European Commission indicates the accounting of soil organic carbon (SOC) variations in space and time as the first step in the strategy for soil protection. It is indeed necessary in evaluating the risk of soil organic matter decline and soil biodiversity decline, and when evaluating the role played by soils in global CO₂ accounting. Previous maps of SOC variations in Italy did not consider the direct effect of climate. There is a marked inter-dependence between SOC and climate.

time series for monitoring vegetation activity and phenology at 10-daily time steps covering large parts of South America

It is widely accepted that natural resources should only be sustainably exploited and utilized to effectively preserve our planet for future generations. To better manage the natural resources, and to better understand the closely linked Earth systems, the concept of Digital Earth has been strongly promoted since US Vice President Al Gore's speech in 1998. One core element of Digital Earth is the use and integration of remote sensing data.
