Food Recovery Hierarchy: Quantifying Food Recovery For The End Users, James Ferguson Dec 2014

Food Recovery Hierarchy: Quantifying Food Recovery For The End Users, James Ferguson

The Last Food Mile Conference

Municipal landfills received 36.4 million tons of food waste in 2012, representing 14.5% of all municipal waste. Looking ahead to 2050 when the world population will exceed 9 billion people, the needed increase in food supply may exceed 70% of current supply. Reducing food waste could provide a significant buffer to help with world food supply. In addition, disposal of food waste to landfills is not a sustainable means of disposal. A priority in reducing food waste is diverting edible food to food banks and other institutions which can utilize edible food. However, for food not acceptable for ...


All About Leftovers, Jonathan Bloom Dec 2014

All About Leftovers, Jonathan Bloom

The Last Food Mile Conference

Wasted food is a particularly galling aspect of our broken food system. The juxtaposition of hunger and waste on this planet is both an affront to common sense and morally callous. Food waste is even more appalling when you consider the environmental impact of modern agriculture. Squandering 30 to 40 percent of available calories while 15 percent of American households are food insecure is ethically and ecologically unsustainable.

There is near universal agreement on the scale of the food waste problem, but little accord on what solutions to prioritize. Where shall we push for action on food waste and where ...

Keynote Presentation: Food, Water, And Energy, Robert Giegengack

The Last Food Mile Conference

While blatant food waste late in the production chain is apparent to most of us, less apparent is the inefficiency of resource use in the processes whereby we produce, harvest, process, package, store, and deliver the food that we eat.

We waste water: 72% of water “used” worldwide is applied directly to cropland, much of it via archaic technology. We move water from where it is plentiful to places where we imagine it will be more useful.

We waste nutrients, even those that we know are in limited supply, by careless or excessive application. Effluent from fertilized cropland has contaminated ...


Global Food Loss And Food Waste And The Environmental Footprint, Barbara Ekwall Dec 2014

Global Food Loss And Food Waste And The Environmental Footprint, Barbara Ekwall

The Last Food Mile Conference

Looking at the global context, the key-note speech will start by examining major trends in food security and nutrition and challenges ahead to feed a world of 9.2 billion people by 2050, 2.3 billion people more than today. It will look at urbanization, changing diets, rising middle class, natural resources and climate change. This is the context in which FAO is fulfilling its mandate to promote food security and nutrition for all, to preserve natural resources, and to promote economic development.

Reducing food loss and waste is an integral part of efforts in view of achieving a zero ...


Minimal Animal: Surveillance, Simulation, And Stochasticity In Wildlife Biology, Etienne S. Benson Jan 2014

Minimal Animal: Surveillance, Simulation, And Stochasticity In Wildlife Biology, Etienne S. Benson

Departmental Papers (HSS)

This article discusses the problematics and potentialities proposed by the "minimal animal" an animal that is nothing but a stochastic pattern across a blank page. The minimal animal was not an invention of the 1960s, but the tracking systems and digital computers that first became available during that period both broadened its reach and changed its character in significant ways.
