Awareness and preparedness for emergencies at local level (APELL) sites in India Awareness and preparedness for emergencies at local level (APELL) sites in India
Awareness and preparedness for emergencies at local level (APELL). APELL achieves its aims through community participation in emergency planning, via a structured dialogue between representatives of the source of the hazard (e.g. a land-owner), local authorities (the emergency services, e.g. fi re and /or police) and community leaders (who inform their constituencies). This dialogue is achieved through a ‘Co-ordinating Group’ which reviews the h...

BedZED (Beddington Zero energy development), location BedZED (Beddington Zero energy development), location
At Beddington, south of London, a housing development known as BedZED (Beddington Zero energy development) was designed from the start to produce little waste of any sort. It was built on a depolluted plot of land, previously used by industry, and recycled materials were used in its construction.

Arctic, topography and bathymetry (topographic map) Arctic, topography and bathymetry (topographic map)
The Arctic represents the northermost area of the World, the Arctic Ocean and the land areas that surrounds it. The region is characterized but cold temperatures, and ice and snow. The summers are short, but with long periods of daylight (midnight sun). The winters are long and cold and with periods with no sun (polar night). The Arctic Ocean is one basin that is mostly covered by sea ice, and is connected to the Pacific and Atlantic Oceans. The ...

Biodiversity loss: state and scenarios 2006 and 2050 Biodiversity loss: state and scenarios 2006 and 2050
These projections of biodiversity loss from 2000 to 2050 were produced by the GLOBIO consortium for UNEP's Global Environment Outlook 4. Across the GEO scenarios and regions, global biodiversity continues to be threatened, with strong implications for ecosystem services and human well-being. All regions continue to experience declines in terrestrial biodiversity in each of the scenarios. The greatest losses are seen in Markets First, followed by ...

Typology of Hazards Typology of Hazards
With growing population and infrastructures the world’s exposure to natural hazards is inevitably increasing. This is particularly true as the strongest population growth is located in coastal areas (with greater exposure to floods, cyclones and tidal waves). To make matters worse any land remaining available for urban growth is generally risk-prone, for instance flood plains or steep slopes subject to landslides. The statistics in the graph opp...

Nile Delta: Potential Impact of Sea Level Rise Nile Delta: Potential Impact of Sea Level Rise
The potential impacts of sea level rise on the Nile Delta are expected to include a decline in water quality that would affect freshwater fish, the flooding of agricultural land and damage to infrastructure. This graphic shows the Nile Delta region as it is today (2002), the area as it would appear with a 0.5 m sea level rise, and the area as it would appear with a 1.0 m sea level rise.

Impact of Temperature Rise on Robusta Coffee in Uganda Impact of Temperature Rise on Robusta Coffee in Uganda
Developing countries, whose economies often rely heavily on one or two agricultural products, are especially vulnerable to climate change. This graphic shows that with an increase of only 2 degrees Celsius, there would be a dramatic decrease in the amount of land suitable for growing Robusta coffee in Uganda.

Projected changes in the Arctic climate, 2090 - with shipping routes Projected changes in the Arctic climate, 2090 - with shipping routes
The averages of the scenarios in the Arctic Climate Impact Assessment (ACIA) are presented in this figure, for the year 2090, with the surface temperatures over land, the size of the polar ice cap, and the outer limits of permafrost. This map features shipping routes in addition - as the sea ice is decreasing, the potential for developing shipping in the Arctic increases.

Rainfall variability and economic growth in Zimbabwe Rainfall variability and economic growth in Zimbabwe
In Zimbabwe, trends in economic growth have been linked to rainfall variability, which can be attributed to sensitivity in the agricultural sector. Improved water resources management is critical to the stability and security that is required for economic development. The recent decline in growth can be caused by other factors such as land reform policies (starting in 2000).

Water, irrigated cropland percentage by region Water, irrigated cropland percentage by region
Irrigated land currently produces 40% of the world’s food on 17% of the world’s land. A broadening of irrigation and more effective rain fed agriculture will be necessary to meet the need for increasing agricultural outputs – for domestic use and exports.

The composition and levels of wealth per capita for low-income countries The composition and levels of wealth per capita for low-income countries
In low-income countries, the natural section represents a quarter of the total wealth, this represents the land that is managed either by household, individual or communally, and the potential for generating income. Physical capital, represents a much smaller share as people will have less potential, compared to higher income countries, to acquire equipment, structures and infrastructure.

Projected temperatures in the 21th century Projected temperatures in the 21th century
Projected Arctic annual land temperature increases for the first half of the 21st century relative to the average temperature for 1980–99. The average of the IPCC models (the blue line) shows an increase of 3ºC by 2050. The averages of the runs from each of the 12 models show increases from 2–4ºC, the range of uncertainty in these model projections.

Trends in Arctic temperature, 1880-2006 Trends in Arctic temperature, 1880-2006
A history of Arctic land temperature anomalies from 1880 through 2006 is shown in this figure. The zero line represents the average temperature for 1961–1990. In the late 1800s the Arctic was relatively cold, although there is some uncertainty around these early temperature estimates. The Arctic warmed by about 0.7ºC over the 20th century. There was a warm period in the 1920s to 1940s and cold periods in the early 1900s and in the 1960s. Over th...

Projected winter temperature changes in the Arctic Projected winter temperature changes in the Arctic
The changes in cold-season mean temperatures over Arctic land regions are broken into three latitudinal bands for each region, as shown on the small map (which has an outer rim of 50° N). Error bars represent standard deviation from the mean. Where greater warming is projected at higher latitudes than at lower latitudes, temperature gradients will be reduced along large north-flowing rivers and this will likely reduce break-up severity. The rever...

Permafrost extent in the Northern Hemisphere Permafrost extent in the Northern Hemisphere
Permafrost zones occupy up to 24 per cent of the exposed land area of the Northern Hemisphere. Permafrost is also common within the vast continental shelves of the Arctic Ocean. This subsea permafrost formed during the last glacial period when global sea levels were more than 100 m lower than at present and the shelves were exposed to very harsh climate conditions. Subsea permafrost is slowly thawing at many locations. Permafrost of various tempe...

Arctic temperatures in the 20th century, modeled and observed Arctic temperatures in the 20th century, modeled and observed
Observed Arctic winter land temperatures and IPCC model recreations for the 20th century. Note that although these model runs are able to capture the range of Arctic warm and cold periods, the timing of the peaks varies, suggesting that the early 20th century warming was due to random causes, while the increases at the end of the century shown by all the models supports CO2 as an external forcing of the Arctic climate system.
