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...

Diet composition
As a result of population growth and changing consumption patterns, the demand for food and production of food is increasing. Cereals such as wheat, rice and maize provide about two-thirds of all energy in human diets (C...

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...

Footprint and population are growing faster than the Earth’s biocapacity
Ecological Footprint accounting quantifies both the annual availability of biocapacity and human demand on that capacity (Wackernagel et al. 2002; Borucke et al. 2013). Since 1961, the total Footprint has increased by 15...

How food is lost and wasted
Globally, one-third of all food produced is either lost or wasted. There is a clear variation between developing and developed countries with regards to food loss and waste. In developing countries, food loss is the gr...

Food loss and waste by region
Ensuring food security for a growing global population is not only about producing more food, but also about reducing the enormous amount of food that is either lost or wasted. Globally, one-third of all food produced is...

Global food loss and waste
Ensuring food security for a growing global population is not only about producing more food, but also about reducing the enormous amount of food that is either lost or wasted. Globally, one-third of all food produced is...

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...

The bushmeat chain reaction
The illicit bushmeat trade involves a series of underlying socio-economic factors, but leads, with rising population densities, to local depletions of wildlife species, and increasingly inside protected areas.

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...

Mercury in food and products
Even now, mercury is commonplace in daily life. Electrical and electronic devices, switches (including thermostats) and relays, measuring and control equipment, energy- efficient fluorescent light bulbs, batteries, masca...

Global soil degradation
In many parts of the world natural resources have been treated as though unlimited, and totally resilient to human exploitation. This perception has exacerbated the conflicting agricultural demands on natural capital, as...

Global trends in cereal and meat production; total use of nitrogen and phosphorus fertilizers; increased use of irrigation; total global pesticides production
Production gains are attributed to improved crop varieties and livestock, soil management, improved access to resources (nutrients and water), infrastructure developments, policy initiatives, microfinance, education, bet...

Natural ecosystem conversion
It is clear that much land needs to be kept for agricultural use but it is also possible that the area required for food production will stabilize in the future.

Ringed seal pupping lair, with the pup in the lair and the female approaching the haul-out hole from the water
Ringed seals are the 'classic' Arctic seal in many regards, being found as far north as the Pole because of their ability to keep breathing holes open in ice that can reach 2 metres in depth. This species is certainly on...
