Land management trumps the effects of climate change and elevated CO₂ on grassland functioning

Journal Articles & Books
Dezembro, 2014

Grasslands cover ˜30% of the Earth's terrestrial surface and provide many ecosystem services. Many grasslands are heavily managed to maximize these services for human benefit, but the outcome of management is anticipated to be increasingly influenced by various aspects of climate change and elevated atmospheric CO₂. The relative importance of global change vs. land management on grasslands is largely unknown.

spatial dimension of urban greenhouse gas emissions: analyzing the influence of spatial structures and LULC patterns in European cities

Journal Articles & Books
Dezembro, 2015

CONTEXT: Integrative mitigation and adaptation strategies are needed to counter climate change. Indicators can be valuable that focus on the specific relevance of cities’ socioeconomic and spatial properties. While previous analyses have identified socioeconomic influences on urban greenhouse gas emissions, information about the role of spatial urban structures and land use and land cover patterns is sparse. OBJECTIVE: This study advances the use of spatial metrics for analyzing the linkages between the spatial properties of a city and its greenhouse gas emissions.

Evaluation of changes in ecological security in China’s Qinghai Lake Basin from 2000 to 2013 and the relationship to land use and climate change

Journal Articles & Books
Dezembro, 2014
China

Ecological security evaluation is an important way to identify the need for improvement in a watershed and to assess the degree of regional sustainable development. Using a driver–pressure–state–exposure–response model, a comprehensive system of ecological security indicators was developed, and it was demonstrated in a case study of the main ecological problems facing the Qinghai Lake Basin.

Combining gray system and poroelastic models to investigate subsidence problems in Tainan, Taiwan

Journal Articles & Books
Dezembro, 2015
Taiwan

Tainan, located in southwestern Taiwan, is a high-risk region for flooding and climate change effect and has a potential for future heavy rains. Groundwater pumping for aquaculture and irrigation along the coastal plain of Tainan is monitored due to subsidence. Predicting future subsidence and understanding the effect of climate change on subsidence can assist with regard to the planning and management of water and land resources in the early stages of subsidence, whose possible damage can thus be avoided.

Climate's Long-term Impact on New Zealand Infrastructure (CLINZI) - A Case Study of Hamilton City, New Zealand

Conference Papers & Reports
Agosto, 2005
Nova Zelândia

Infrastructure systems and services (ISS) are vulnerable to changes in climate. This paper reports on a study of the impact of gradual climate changes on ISS in Hamilton City, New Zealand. This study is unique in that it is the first of its kind to be applied to New Zealand ISS. This study also considers a broader range of ISS than most other climate change studies recently conducted. Using historical climate data and four climate change scenarios, we modelled the impact of climate change on water supply and quality, transport, energy demand, public health and air quality.

Climate change and grazing interact to alter flowering patterns in the Mongolian steppe

Journal Articles & Books
Dezembro, 2014
Mongólia

Socio-economic changes threaten nomadic pastoralism across the world, changing traditional grazing patterns. Such land-use changes will co-occur with climate change, and while both are potentially important determinants of future ecosystem functioning, interactions between them remain poorly understood. We investigated the effects of grazing by large herbivores and climate manipulation using open-top chambers (OTCs) on flower number and flowering species richness in mountain steppe of northern Mongolia.

Evaluating the relative impact of climate and economic changes on forest and agricultural ecosystem services in mountain regions

Journal Articles & Books
Dezembro, 2013
Suíça

Provisioning of ecosystem services (ES) in mountainous regions is predicted to be influenced by i) the direct biophysical impacts of climate change, ii) climate mediated land use change, and iii) socioeconomic driven changes in land use. The relative importance and the spatial distribution of these factors on forest and agricultural derived ES, however, is unclear, making the implementation of ES management schemes difficult.

Climate change perceptions and adaptive responses of smallholder farmers in central highlands of Ethiopia

Journal Articles & Books
Dezembro, 2012
Etiópia

This paper presents an assessment of smallholder farmers’ perceptions of climate change, its impacts on agricultural production and adaptive responses in the central highlands of Ethiopia. The findings show that increased temperature and decreased rainfall are widely held perceptions; all respondents stated that they had observed increase in temperature and decrease in annual and seasonal rainfall amounts.

multi-scale hierarchical framework for developing understanding of river behaviour to support river management

Journal Articles & Books
Dezembro, 2016

This paper introduces this special issue of Aquatic Sciences. It outlines a multi-scale, hierarchical framework for developing process-based understanding of catchment to reach hydromorphology that can aid design and delivery of sustainable river management solutions. The framework was developed within the REFORM (REstoring rivers FOR effective catchment Management) project, funded by the European Union’s FP7 Programme. Specific aspects of this ‘REFORM framework’ and some applications are presented in other papers in this special issue.

Early human impact (5000–3000 BC) affects mountain forest dynamics in the Alps

Journal Articles & Books
Dezembro, 2015

The resilience, diversity and stability of mountain ecosystems are threatened by climatic as well as land‐use changes, but the combined effects of these drivers are only poorly understood. We combine two high‐resolution sediment records from Iffigsee (2065 m a.s.l.) and Lauenensee (1382 m a.s.l.) at different elevations in the Northern Swiss Alps to provide a detailed history of vegetational changes during the period of first pastoralism (ca. 7000–5000 cal. BP, 5000–3000 BC) in order to understand ongoing and future changes in mountain ecosystems.

Methods and tools for addressing natural disturbance dynamics in conservation planning for wilderness areas

Journal Articles & Books
Dezembro, 2014

AIM: New conservation approaches that account for broad‐scale ecological processes must underpin decisions about conservation planning in the world's remaining wilderness areas. Our goal is to make the relevant tools and methods that have been developed by conservation scientists accessible to conservation practitioners working towards wilderness preservation. LOCATION: Wilderness areas, in particular the North American boreal region.

Accelerating the domestication of forest trees in a changing world

Journal Articles & Books
Dezembro, 2012

In light of impending water and arable land shortages, population growth and climate change, it is more important than ever to examine how forest tree domestication can be accelerated to sustainably meet future demands for wood, biomass, paper, fuel and biomaterials. Because of long breeding cycles, tree domestication cannot be rapidly achieved through traditional genetic improvement methods alone. Integrating modern genetic and genomic techniques with conventional breeding will expedite tree domestication.
