Stretching the ecosystems beyond their limits
Ecological Footprints tell the extent to which people use what the biosphere provides. The Footprint methodology can therefore also measure the environmental demands of food production and show to what extent food produc...

Will there be enough food for 9.6 billion people?
About 200 000 to 230 000 people are added to the world food demand daily, and the UN estimates that by 2050 the world population will reach 9.6 billion (UN DESA 2013). Developing countries, especially in sub-Saharan Afri...

Restoring ecosystems could feed 740 million people
There are great potentials in restoring degraded land. Globally there are over 560 million hectares of degraded agricultural land (Oldeman 1992) that could be restored through sustainable agricultural practices and green...

Land types needed for food production
The average “foodprint” today is at least 0.66 global hectares per person, which corresponds to more than one-third of the Earth’s biocapacity, or about one-fourth of humanity’s Ecological Footprint (calculations based o...

Cereal production increase
An estimated 37.6 per cent of the world’s total land area is used for agriculture (FAO 2013a), and this ratio continues to expand. The past 50 years have seen global crop production expand threefold, with cereal producti...

Benefits of SLCP controle measures for Agriculture
Implementation of the 16 control measures specified in the Time to Act publication is expected to have significant benefits for agriculture worldwide. Rapid reduction of methane and sot has the potential to avoid an annu...

Effects on Agriculture - SLCPs, a Threat to Agricultural Productivity
SLCPs, especially tropospheric O3, detrimentally impact ecosystems including crop yields, and are affecting food security. Present day global relative yield losses due to tropospheric O3 exposure has been estimated for f...

Soy Expansion in the Brazilian Amazon frontier
Often, small-scale farmers settle the areas along logging roads in order to burn secondary or cleared forest for crop production. These farmers are eventually pushed or bought-out by large-scale cattle ranchers or soy p...

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...

Women in government decision-making positions in 1998
Women are responsible for most household work (and in many parts of the world the majority of agricultural production), but women’s rights to own land or control resources are constrained, often by traditional customs an...

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...

The disappearance of the Aral Sea
The demise of the Aral Sea in central Asia was caused primarily by the diversion of the inflowing Amu Dar’ya and Syr Dar’ya rivers to provide irrigation water for local croplands. These diversions dramatically reduced th...
