Biodiversity in the Caspian Sea
With the opening of the Volga-Don canal in 1952
navigation between the oceans and the Caspian became
possible. Contact between the previously secluded
Caspian marine ecosystem and the outside world was
consequently inevitable. The connection led to the introduction of various alien species (plants and animals not native to the habitat). The most threatening event for the Caspian ecosystem was the arrival of the North American comb jelly (Mnem...

Impact of land conversion on biodiversity
The impacts of land conversion on biodiversity may
be significant. The degree of impact relates to many
factors, including where and how the bioenergy
product is cultivated. This figure represent the short-term impacts of land conversion.

Biofuels crops and biodiversity
Biofuels pose several environmental and social
risks. Therefore, to be truly a part of the green
economy, biofuels need to comply with a set of
safeguards along the entire production chain. Any
bioenergy development strategy must integrate
such safeguards at all levels, from policy to
investments and the project itself.
As impacts can be significant, they need to be
assessed from a number of angles, including:
• Direct and indirect lan...

Estimated costs and benefits of restoration projects in different biomes
Biodiversity is the basis for any development; it is the
natural capital, the stock of natural ecosystems, which
provide services for any human activity. As pointed
out above, the main immediate threat to biodiversity
from biofuel production is through changes in land
use, but longer-term threats may come from the
spread of invasive species and uncontrolled use of
genetically modified (GM) organisms.
The environmental and social costs o...

Biodiveristy in Central Asia
Caspian and Balkhash endemic species are under threat of extinction. It is estimated that ten percent of total area needs to be protected in order to sustain development and the countries of the region are seriously behind that benchmark.

Dobris+3: overall pan-european assessment
The graph shows Dobris+3: overall pan-european assessment. It describes positive or negative developments within various environmental branches, such as climate change, biodiversity and urban environment, the occurence of environmental policies as well as the principal drivers of said environmental developments.

Human impact, Arctic Russia 2002 and scenarios
Presentation of impact analysis from the Europe and Asia GLOBIO2 analysis and scenarios prepared for the GEO-3 publication. Much of Arctic Russia is very sparsely populated and will remain one of the World's few wilderness areas.

Preliminary assessment of the Amazonian region
Poster that was prepared as a proof of concept in the development of the GLOBIO2 model. The greater Amazonian region is a giant mega watershed with many remote areas with very little development and this area harbours a massive amount of water resources for the population in the densily inhabited areas downstream, as well as areas of very high and unique biodiversity.

Human impact, Norway 2002-2050 (with protected areas)
Analysis of the suggested development of impact on ecosystems through human activities. The GLOBIO-2 model uses settlements and infrastructure, such as roads, pipelines and powerlines as proxies for stress and fragmentation.

Human impact, Greater Asian Mountains region 2000 and scenarios for 2030
Changes in the Greater Asian Mountains area with reduced biodiversity and ecosystem function as a result of human development in infrastructure and associated resource exploitation between 2000 and 2030, given different scenarios. Security first and Markest first indicate situations where market deiven forces determine rate and extent of development while policy first represents a moderate growth rate.

The encroachment of road networks in Northern Norway, 1940-2000
The development of human settlements and the road network linking them together are fragmenting natural habitats especially for larger mammals, such as bears, wolves or reindeer. The nature loses its status as wilderness.

Based on population pressures the GLOBIO2 model has assessed the current and future human impacts on Great Ape (Orangutan) habitat in Southeast Asia. The remaining forests are projected to be subject to piecemal fragmentation and loss of wilderness characteristics, in the Orangutan range.

Changes in biodiversity and ecosystems based on human impact 1990-2050
Modelling, using the GLOBIO1 model, over the Arctic, assessing the impacts on the environment based on infrastructure development between 1990 and 2050 in three different scenarios. The development of roads, pipelines and powerlines fragments the natural habitats and reduces the wilderness qualities.
