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 ...


Nutrient Reduction Strategy Update And Opportunities For Agribusinesses, Jamie Benning Dec 2014

Nutrient Reduction Strategy Update And Opportunities For Agribusinesses, Jamie Benning

Proceedings of the Integrated Crop Management Conference

The Iowa Nutrient Reduction Strategy is a science-based framework that identifies in-field, edge of field, and land use practices that minimize loss of nitrogen and phosphorus to surface water. In addition to reductions in agricultural non-point sources of nutrients, the strategy also identifies reductions for non-agricultural point sources such as municipal wastewater treatment plants. The Hypoxia Task Force identified a goal of reducing the total nitrogen and total phosphorus load by 45%. The Iowa Nutrient Reduction Strategy outlines the effectiveness of the identified agricultural practices to assist farmers in selecting practices individually or in combination to meet their nutrient reduction ...


Evaluating Contaminants Of Emerging Concern In Commercial Biosolid-Based Fertilizers, John Hemmerling, Michael L. Mashtare, Linda S. Lee Aug 2014

Evaluating Contaminants Of Emerging Concern In Commercial Biosolid-Based Fertilizers, John Hemmerling, Michael L. Mashtare, Linda S. Lee

The Summer Undergraduate Research Fellowship (SURF) Symposium

The production and popularity of commercially available biosolid-based fertilizers are increasing because of their economic, environmental, and plant nutrition benefits, particularly in urban and suburban areas. Because biosolid-based fertilizers are derived from waste water treatment plant residuals, we hypothesized that there is the potential for micropollutants to persist in these products. Their presence would be of particular concern due to their potential impact on human and ecological health and risk of bioaccumulation. This study involves quantifying contaminants of emerging concern in three biosolid-based fertilizers, and 2 non-biosolid-based fertilizers, a composted animal manure and an organic compost. Our extraction method employed ...


Precipitation Variability And Nitrogen Deposition Alter Root Distribution In A Tallgrass Prairie, Emmalyn P. Terracciano, Michael Schuster, Jeffrey Dukes Aug 2014

Precipitation Variability And Nitrogen Deposition Alter Root Distribution In A Tallgrass Prairie, Emmalyn P. Terracciano, Michael Schuster, Jeffrey Dukes

The Summer Undergraduate Research Fellowship (SURF) Symposium

Climate change and increases in nitrogen deposition impact ecosystems globally. Projected atmospheric warming allows rain to fall in larger events with longer dry periods in between, increasing rainfall variability in many regions. Concurrently, the combustion of fossil fuels and the heavy use of nitrogen fertilizers continue to increase the availability of nitrogen globally. However, not much is known about how these global change factors, increased rainfall variability and nitrogen deposition, interact with each other to affect ecosystem functions, particularly belowground where root production contributes to soil carbon pools- an important component in regulating climate. In order to study these factors ...


The State Of The Upper Bay Of Panama Wetlands: Ecological Significance, Environmental Policy, Urbanization, And Social Justice, Madeline A. Price May 2014

The State Of The Upper Bay Of Panama Wetlands: Ecological Significance, Environmental Policy, Urbanization, And Social Justice, Madeline A. Price

Celebration

I conducted this research while studying abroad with SIT Panama: Tropical Ecology, Marine Ecosystems, and Biodiversity Conservation. This is a multidisciplinary investigation of the Upper Bay of Panama wetlands, a 49,000 hectare region east of Panama City that features mangrove, intertidal mudflat, and grassland habitat internationally recognized as a stopover site for two million shorebirds every migration season. However, with economic pressure to increase urban development in the area, this land’s protected status under the Ramsar convention was suspended for a year in April 2012. By compiling scientific studies, news articles, photographs, and interviews with local conservationists and ...


Salmonid Early Response To Restored Freshwater Floodplain, Erin Morgan, Jeffery R. Cordell, Lauren Rich May 2014

Salmonid Early Response To Restored Freshwater Floodplain, Erin Morgan, Jeffery R. Cordell, Lauren Rich

Salish Sea Ecosystem Conference

Shortly after the construction of the Hansen Creek floodplain restoration project in 2010-2011, we conducted a pilot study of the initial use of the site by juvenile salmonids and the early development of invertebrate communities. We found that juvenile Coho salmon collected from the restored floodplain during periodic inundation events had higher instantaneous rations (a measure of feeding intensity) than Coho collected during regular monthly sampling in the creek channels. The floodplain site also had consistently higher insect abundances. Applying the data and lessons learned from the pilot study, we undertook a more comprehensive 13-month study of Hansen creek and ...

"Changing roles of market, state and civil society: the case of coffee cooperatives and small farmers in Mexico"

Abstract

In this paper, we investigate how civil society organizations, in particular coffee cooperatives, are responding to the growth of market power and the decline of government’s role in the coffee regime. At the international and national (Mexican) levels a strong neoliberal agenda skewed towards the freedom of the market has changed the relationships with the state and civil society. The strong role of the market, and the volatility of international coffee prices as well as the lack of assertive agricultural ...

Cropping And Livestock Systems: Manure And Soil Quality, Jerry L. Hatfield Jan 2014

Cropping And Livestock Systems: Manure And Soil Quality, Jerry L. Hatfield

Driftless Region Beef Conference

Agriculture across the Midwest was founded on the integration of crop and livestock systems. This integration was based on the utilization of crop production for animal feed and utilization of the manure as the nutrient sources for the crops. This same integration of components of the agricultural system exists today but we no longer view these components as an integrated puzzle and tend to consider crop and livestock production as separate systems. The Midwest is one of the most intensive agricultural systems leading in corn and soybean production, dairy, hog and poultry production and can serve as an example of ...
