A new study submitted to us by an FCRN member discusses the virtual land footprint associated with regional supply capacities.
A recent paper published in BioScience articulates the need for a new vision and new goals for the sustainable intensification of agriculture, moving away from the often cited statement that food production must double by 2050 to feed the world's growing population.
This paper argues that the strength of the linkages between the ‘Human System’ and the Earth system warrants a new paradigm of modeling which incorporates key factors in one system as variables of a model of the other.
This short perspective in the journal Science reviews how the rise of urbanization is transforming food systems in many areas, and argues for further research on this topic.
As the global population grows and food consumption patterns shift towards more resource intensive foods, food loss and waste (FLW) is becoming a topic of increasing importance due to its impact on future food availability and - via the greenhouse gas emissions embodied in its production - on climate change.
Global trends of population growth, rising living standards and the rapidly increasing urbanized world are increasing the demand on water, food and energy. Added to this is the growing threat of climate change which will have huge impacts on water and food availability.
This article discusses the interplay of food requirements, food waste, food deficits, and associated GHG emissions. It estimates the agricultural GHG emissions associated with food waste, argues the importance of reducing food waste as a contribution to addressing GHG emissions and proposes a standardized method for estimating food waste for all countries.
This report entitled 'Mitigating risks and vulnerabilities in the energy-food-water nexus in developing countries' analyses global nexus interconnections (such as the dependence of food systems on energy at every stage of the food value chain) and identifies key challenges for food, energy and water security, which include economic and population growth, resource depletion, environmental degradation, climate change and globalisation.
This paper published in PLOS ONE, entitled Global Food Demand Scenarios for the 21st Century, describes a transparent method for constructing specific food demand scenarios for total and animal-based calories. It requires only population and income projections as input, with no information on the food supply side needed.
The food and agriculture (F&A) industry must increase production, availability and access to food significantly over the next ten years if it is to meet the demands of a larger, increasingly urban global population according to a new report presented by Rabobank at Expo Milano 2015.
This new report “Planetary Health: Safeguarding Human Health in the Anthropocene Epoch” launched by The Rockefeller Foundation - Lancet Commission argues that changing environmental conditions such as increased carbon dioxide emissions, rampant use of fertilizer and the acidification of the oceans could lead to major health challenges for millions of people. Increasing population, unsustainable consumption and production and the over-exploitation of natural resources are also factors straining the planet's resources and having an impact on human health.
This study is the first to quantify the relationship between human population growth and energy use on an international scale. It explains how global population growth has begun, in the past 50 years, to catch up with energy consumption for the first time in 500 years. Until that point, each generation had produced more energy per person than its predecessor, which allowed for an increase in Earth's carrying capacity and in the number of people it could sustain at equilibrium.
This paper provides the first estimate of energy and material flows in the world’s 27 megacities (cities with over 10 million inhabitants). These megacities are home to 6.7 per cent of the world's population, but consume 9.3 per cent of global electricity and produce 12.6 per cent of global waste. The authors establish statistical relations for energy use, transport, water use, waste and so forth and factors such as average temperature, urban form, level and type of economic activity, and population growth. This allows the researchers to evaluate which cities have high versus low levels of consumption and which ones make efficient use of resources.
The authors behind this study say that climate change has substantially increased the prospect that crop production will fail to keep up with rising demand in the next 20 years.
