The Environmental Food Crisis - The Environment's Role in Averting Future Food Crises
A new rapid response assessment report released by UNEP warns that up to 25% of the world’s food production may become lost due to environmental breakdown by 2050 unless action is taken. Prepared by the Rapid Response Assessment Team at UNEP/GRID-Arendal and UNEP-WCMC, the report provides the first summary by the UN of how climate change, water ...

Crushed by war and world conflicts
Conflicts increase the risk of food supply instability tremendously (Figure 31). Countries in conflict and post-conflict situations tend to be food insecure, with more than 20% of the population, and in many cases far...

Country income groups (World Bank classification)
There are huge regional differences in the above trends. Globally, poverty rates have fallen from 52% in 1981 to 42% in 1990 and to 26% in 2005. In Sub-Saharan Africa, however, the poverty rate remained constant at ar...

Water requirements for food production 1960-2050
The requirements for water in agriculture will need to increase in order to meet the Millennium Development Goal 1, target 2 'Halve, between 1990 and 2015, the proportion of people who suffer from hunger'. To decrease hu...

Market access (estimated travel time) in agricultural areas
Accessibility to food is also determined by the long-term trend in food prices (which is a different issue from price volatility). The rising trend in global food prices is likely to persist in the next decade. In the...

Projected agriculture in 2080 due to climate change
With our climate changes, we have to adapt our ways to a new environment – in most cases warmer and possibly wetter and drier. Projections on the climate in the future provide some guidance for us, but how can we create ...

Trends in mean depth of fish catches
Food losses in the field (between planting and harvesting) could be as high as 20–40% of the potential harvest in developing countries due to pests and pathogens (Kader, 2005). Postharvest losses vary greatly among co...

Projected land use changes
A central component in preventing loss of biodiversity and ecosystem services, such as provisioning of water, from expanding agricultural production is to limit the trade-off between economic growth and biodiversity b...

Trends in world agricultural exports
The availability of food within a specific country can be guaranteed in two ways: Either by food production in the country itself or by trade. The first option has been discussed extensively in the previous chapters. ...

Selected drought events in Africa, 1981-1999, and livestock impacts
Water scarcity in terms of drought or depleted groundwater could therefore have great impacts on livestock and rangelands. These interactions are also complex. While drought can directly threaten livestock, other fact...

Trends in urban and rural populations, less developed regions, 1960-2030 (estimates and projections)
According to the latest UN estimates, almost all of the world’s population growth between 2000 and 2030 will be concentrated in urban areas in developing countries (Figure 32). By 2030, almost 60% of the people in dev...

Biofuels production 2005, by country (ethanol and biodiesel)
Production of crops for biofuels also competes with food production (Banse et al., 2008). Indeed, the corn equivalent of the energy used on a few minutes drive could feed a person for a day, while a full tank of ethan...

A photographic impression of the gradual changes in two ecosystem types
Globally, over 1,000 (87%) of a total of 1,226 threatened bird species are impacted by agriculture. More than 70 species are affected by agricultural pollution, 27 of them seriously. Europe’s farmland birds have decl...
