Key relationships between future challenges and agricultural knowledge, science and technology (AKST) options for action
The general model has been to continuously innovate, reduce farm gate prices and externalize costs. This model drove the phenomenal achievements of AKST in industrial countries after WWII and the spread of the Green Revo...

Loss of Great Ape habitat 2002-2032 (Southeast Asia)
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 fragment...

Human impact, year 2032 (policy first scenario)
The GLOBIO-2 model is based on settlements and modern infrastructure such as roads, powerlines and pipelines. This map presents the possible situation in 2032, using the GEO-3 policy first scenario. This scenario suggest...

Human impact, year 1700 (approximately)
The GLOBIO-2 model is based on settlements and modern infrastructure such as roads, powerlines and pipelines. This map presents the situation as it could have been before the advent of industrialization, with very little...

Modeled temperature compared to observed temperature for the last 150 years
As we can see from models of temperature changes caused by natural forcing, we should have observed a decrease in the global average temperature lately, but we have not. We have observed an increase. A climate model c...

Radioactive, chemical and biological hazards in Central Asia
The Soviet development model for Central Asia was based on building large-scale irrigation schemes enabling the region to become a major cotton producer and expanding the mining and processing industry. Industrial operat...

Projected temperature changes, 2000 to 2100 scenario
Average temperatures changes in the world according to the GFDL model (doubling of CO2 and temperature increase by 3,7°C from 2000 to 2100). According to this model, the changes will be most severe in the Arctic and the ...

Climate change scenarios for desert areas by 2050
In desert areas by 2050, the majority of the temperature increase, according to the NCAR-CCSM3 model (and the IPCC SRES A2 scenario), will occur in the Northern Sahara, western Australia and in the inland deserts of Nort...

Land cover changes in desert areas 1700,1900,2000 and 2050
The main land use change in desert areas has been the conversion of relatively barren drylands for agricultural needs, partially through irrigation. The conversion has historically primarily been to use the land for graz...

Human impact in desert areas 1700,2000 and 2050
The impact of human activities on wilderness qualities has been modelled using the GLOBIO-2 model. The model uses infrastructure and settlements as proxies and measure the degree by which habitats have reduced their wild...

Climate scenarios for cereal production
The figure shows change in cereals production under three different GCM equilibrium scenarios (percent from base estimated in 2060). While there are still uncertainties about whether climate change will cause global agri...

Projected changes in CO2 and climate: assumptions in the IPCC 1992 scenarios
Projected anthropogenic CO2 emissions from fossil fuel use, deforestation and cement production are shown for some of the IPCC emission scenarios. The highest emission scenario - IS92e - assumes moderate population grow...

Loss of Great Ape habitat 2002-2032 (Africa)
Based on population pressures the GLOBIO2 model has assessed the current and future human impacts on Great Ape habitat in Africa (Chimpanzee, Bonobo and Gorilla). The analysis shows a vast reduction of some of the world'...
