Characterising spatiotemporal environmental and natural variation using a dynamic habitat index throughout the province of Ontario

Understanding changes in landscape productivity patterns is critical for management of ecosystems, characterising biodiversity, and monitoring climate change. Vegetation productivity, a key functional component of terrestrial ecosystems, can be readily monitored using remote sensing and can also be combined with other spatial information, such as land cover and topography, to provide a more comprehensive understanding, at the landscape scale, of ecosystem dynamics.

Relationships between climate, water resources, land use and diffuse pollution and the significance of uncertainty in climate change

Journal Articles & Books
Décembre, 2012

A multi-scale study has been undertaken to explore the relationships between climate, water resources, land use and diffuse pollution in order to assess the significance of projected future changes in climate and the uncertainty inherent in these projections. Two climate simulations from the GCM–RCM Perturbed Physics Ensemble developed by the UK Met Office Hadley Centre, broadly representing the extremes of future climate simulations, were downscaled and applied to a grid-based dynamic national water balance and nitrate model for Scotland.

Determining the effects of land consolidation on fuel consumption and carbon dioxide emissions in rural area

Expected achievement of land consolidation depends on the priority given to the protection of water, soil and air quality which are the elements of rural environmental balance. Today, many of researches have carried out to determine the effects of land consolidation on the local hydrology and agricultural productivity.

Water erosion-induced CO₂ emissions from tilled and no-tilled soils and sediments

The acceleration of soil erosion by water in most regions of the world in response to the anthropogenic modification of landscapes is a serious threat to natural ecosystem functionalities because of the loss of invaluable constituents such as soil particles and organic carbon (OC). While soil OC erosion is likely to be a major component of the global C cycle, water erosion-induced CO₂ emissions remain uncertain. In this study, our main objective was to compare the release of CO₂ from eroded topsoils and from the sediments exported by diffuse erosion during an entire rainy season.

Reducing Emissions from Deforestation and Forest Degradation (REDD) in Apuí, Southern Amazonas: Challenges and Caveats Related to Land Tenure and Governance in the Brazilian Amazon

Journal Articles & Books
Décembre, 2012

Climate change mitigation mechanisms related to reducing emissions from deforestation and forest degradation (REDD) may provide significant opportunities for re-arranging political networks and overcome forest governance problems, of which land tenure is the main constraint for REDD and reforestation projects in the Amazon. We present a case study of a pilot REDD project associated with reforestation and payment for environmental services in Apuí, southern Amazonas.

Vulnerability, forest-related sectors and climate change adaptation: The case of Cameroon

Journal Articles & Books

Cameroun

In Cameroon and elsewhere in the Congo Basin, the majority of rural households and a large proportion of urban households depend on plant and animal products from the forests to meet their nutritional, energy, cultural and medicinal needs. This paper explores the likely impacts of climate-induced changes on the provisioning of forest ecosystem goods and services and its effect on the economic and social well-being of the society, including the national economy and the livelihoods of forest-dependent people.

Booming during a bust: Asynchronous population responses of arid zone lizards to climatic variables

Journal Articles & Books
Décembre, 2012

The productivity of arid environments and the reproductive success of vertebrates in these systems, are typically thought to be primarily influenced by rainfall patterns. Data from our 15 year study at an Australian arid zone site reveals asynchronous demographic responses to rainfall and other climatic variables among different lizard species.

Ecology of Testate Amoebae in Moorland with a Complex Fire History: Implications for Ecosystem Monitoring and Sustainable Land Management

Journal Articles & Books
Décembre, 2012

Testate amoebae represent a crucial component of soil microfauna and have been studied extensively in ombrotrophic peatlands. However, little is known about their ecology in moorlands which are important habitats in terms of biodiversity and carbon storage potential. Moorlands are under threat from a range of factors such as drainage, burning, over grazing, pollution and climate change.

Perception and decisions in modeling coupled human and natural systems: A case study from Fanjingshan National Nature Reserve, China

Modeling human–environment systems presents many challenges, including incorporating structure and agency and addressing uncertainty in system components and relationships. Exploring perceptions not only gives us insight into decision-making (agency) but also reveals structural constraints influencing those decisions (including perceived constraints). This study focuses on the human–nature dynamics of Fanjingshan National Nature Reserve (FNNR) in China, a biodiversity hotspot and the only habitat for the Guizhou golden monkey (Rhinopithecus brelichi).

REDD Policy Impacts on Indigenous Property Rights Regimes on Palawan Island, the Philippines

Philippines

Several Southeast Asian states have been working feverishly to design and implement REDD policy frameworks to fulfil their commitment to global climate change mitigation. In doing so, state agencies will be challenged to design REDD plus policies that value and conserve forest carbon in ways that align with national policies and local priorities for managing forest landscapes defined by complex property rights regimes.

Bundling of ecosystem services to increase forestland value and enhance sustainable forest management

There has been increasing interest in the use of market-based approaches to add value for forestland and to assist with the conservation of natural resources. While markets for ecosystem services show potential for increasing forestland value, there is concern that the lack of an integrated program will simply add to the complexity of these services without generating significant public benefits.

Defining Spaces of Resilience within the Neoliberal Paradigm: Could French Land Use Classifications Guide Support for Risk Management Within an Australian Regional Context?

Journal Articles & Books
Décembre, 2012

An effective response to future risk within socio-ecosystems will require the retention of local diversity, not just in more vulnerable communities on the margins but also in regions vital to industrialised countries. A case study is presented that examines agroecosystem vulnerability to climate change within an Australian multifunctional rural landscape adjacent to the city of Adelaide.
