DOWNLOAD EBOOKThe European Arctic and Alpine regions are experiencing large environmental changes. These changes may have socio-economic effects if the changes affect the bioproduction, which form the basis for the marine and terrestrial food chains. This uniquely multidisciplinary book presents the various aspects of contemporary environmental changes in Arctic and Alpine Regions.

DOWNLOAD EBOOKAs human populations expand and have increasing access to technol ogy, two general environmental concerns have arisen. First, human pop ulations are having increasing impact on the earth system, such that we are altering the biospheric carbon pools, basic processes of elemental cycling and the climate system of the earth. Because of time lags and feedbacks, these processes are not easily reversed. These alterations are occurring now more rapidly than at any time in the last several million years. Secondly, human activities are causing changes in the earth's biota that lead to species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Although environmental change is potentially reversible at some time scales, the loss of species is irrevo cable. Changes in diversity at other scales are also cause for concern. Habitat fragmentation and declines in population sizes alter genetic di versity. Loss or introduction of new functional groups, such as nitro gen fixers or rodents onto islands can strongly alter ecosystem processes. Changes in landscape diversity through habitat modification and frag mentation alter the nature of processes within and among vegetation patches. Although both ecological changes altering the earth system and the loss of biotic diversity have been major sources of concern in recent years, these concerns have been largely independent, with little concern for the environmental causes the ecosystem consequences of changes in biodiversity. These two processes are clearly interrelated. Changes in ecological systems cause changes in diversity.

DOWNLOAD EBOOKThe goals of the second volume of the AHDR – Arctic Human Development Report: Regional Processes and Global Linkages – are to provide an update to the first AHDR (2004) in terms of an assessment of the state of Arctic human development; to highlight the major trends and changes unfolding related to the various issues and thematic areas of human development in the Arctic over the past decade; and, based on this assessment, to identify policy relevant conclusions and key gaps in knowledge, new and emerging Arctic success stories. The production of AHDR-II on the tenth anniversary of the first AHDR makes it possible to move beyond the baseline assessment to make valuable comparisons and contrasts across a decade of persistent and rapid change in the North. It addresses critical issues and emerging challenges in Arctic living conditions, quality of life in the North, global change impacts and adaptation, and Indigenous livelihoods. The assessment contributes to our understanding of the interplay and consequences of physical and social change processes affecting Arctic residents’ quality of life, at both the regional and global scales. It shows that the Arctic is not a homogenous region. Impacts of globalization and environmental change differ within and between regions, between Indigenous and non-Indigenous northerners, between genders and along other axes.

DOWNLOAD EBOOK"The Arctic region is characterized by some of the largest continuous intact ecosystems on the planet, but is facing increasingly larger threats. These threats include the full range of stressors known from other parts of the world, namely habitat loss and fragmentation from infrastructure and industrial development, chemical pollution, overharvesting, climate change and invasive species infestations. Many of these pressures are mainly globally driven, including climate change, long-range transported pollution and even invasive species infestations. Others, such as harvesting and fragmentation are directly under Arctic governance, though often driven from demands outside of the Arctic region. This report takes a broad view of existing multilateral environmental agreements (MEAs) and examines the role of the global environment in impacting and influencing the efficiency of Arctic MEAs in protecting biodiversity and in sustainable development. The report allows governing and scientific bodies of MEAs, as well as national decision-makers, to better direct their programmes of work and other activities to address the needs of Arctic biodiversity and the region's local and Indigenous Peoples"--From publisher website.
