The Truth Behind Avocado Expansion In The Algarve: A Synthesis Of Public, Environmental Associations, And Government Perspectives And Response, Mandy Ausman

Independent Study Project (ISP) Collection

Avocado expansion has exponentially increased in the Algarve region of southern Portugal in recent years. The surge in expansion has provoked contention and discrepancy in the media regarding how and if avocado production can persist in the water-scarce region due to worsening drought conditions related to climate change coupled with the fruit’s significant water footprint. This paper aims to synthesize the arguments and response of the public, environmental associations, and government agencies to the expansion of avocado production in the water- scarce region of the Algarve, highlight the region’s current challenges of avocado expansion and water management regulation, and analyze …

Carbon Farming: A Preliminary Economic Analysis Of Carbon Credits For No-Till And Cover Crops, Drew Havens, Richard K. Perrin, Lilyan E. Fulginiti

Cornhusker Economics

Summary Based on experimental data about the amount of carbon sequestered and estimated implementation costs, our preliminary results show that the average cost of sequestering carbon via no-till (about $22 per ton of CO₂e) appears to be much lower than the $51 per ton social value of sequestering that ton. In contrast, our preliminary results show that the average costs of sequestration via adoption of cover crops is much higher, about $60 per ton. Depending on how accurate soil carbon models are in predicting sequestration on individual fields to qualify them for enrollment, reimbursement costs for planting cover …

Teaching Agroecology: Preparing Students For Navigating Uncharted Territory, Charles A. Francis, Steve Gliessman

Department of Agronomy and Horticulture: Faculty Publications

Agroecologists understand that farming and food systems are more complex than the aggregation of their components. This realization drives our choices of learning strategies and activities that will prepare students for complexity and uncertainty. Our quest for a just, sustainable, and nutritious food system adequate to equitably serve everyone on the planet today and into the future is an enormous challenge. An undertaking of this magnitude will be met only with major adjustments informed by thoughtful teaching and practicing problem solving skills through a new educational lens. The principles of agroecology help us focus this lens on the wicked problems …

The Impact Of Policy Design On Willingness To Pay For Ecosystem Services From Prairie Strips, Karina Schoengold, Badri Khanal, Taro Mieno, Lisa Schulte Moore

Cornhusker Economics

Ecosystem services from farmland conservation are public good benefits. The value of these benefits is primarily measured using methods that determine the willingness to pay (WTP) for those benefits. Prairie strips, a farmland conservation practice, provide ecosystem services such as improved water quality, soil health, and biodiversity (Schulte et al., 2017). The state of Iowa is a major corn producer and contributes significant amounts of nitrogen and phosphorous to the Gulf of Mexico (Alexander et al., 2008). The development of conventional agricultural systems has also resulted in a significant loss of biodiversity, including a dominant land cover of tallgrass prairie. …

Comparative Analysis Of Zoning Of Food Retail And Urban Agriculture For Richmond, Virginia, Hannah Quigley Mph, Meghan Dinofrio, Sarah Shaughnessy Mph, Aicp, John C. Jones Mpa, Phd

Environmental Studies Publications

This research partnership between local public health practitioners and urban food systems scholars suggests improvements to City of Richmond, Virginia’s zoning code related to food retail and urban agriculture by drawing inspiration from other American central cities. The authors created an empirical process to identify potential sister cities to Richmond as a source for high quality comparative examples. Next, the authors then engaged in a non-empirical, purposive process of identifying potential zoning code improvements from both identified sister cities, as well as other communities. Time and capacity constraints dictated the non-empirical nature of this search. Recommendations for improvement to Richmond’s …

Regenerating Agroecosystems By Overcoming Human Exceptionalism In Designing For Increased Equity Of Benefits From Ecoservices, Ali Loker, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

Our commentary explores three critical issues related to ecosystem services. First is how ecoservices are currently designed and implemented primarily for human benefit without concern for how these impact other species. We conclude that awareness of this imbalance is the first step toward meaningful change. Second we observe that human exceptionalism guides most decisions, and ask whether we can overcome this mind-set to embrace ecoregeneration and design of resilient and mutually beneficial agroecosystems. Our attitude toward the challenge and moving toward greater humility about human roles that guide management decisions in the ecosystem is a requisite for change. Third we …

Land Use As A Predictor Of Water Hyacinth (Eichhornia Crassipes) Presence On The Entebbe Coast Of Lake Victoria, Uganda, Zachary Hoffman

Independent Study Project (ISP) Collection

Lake Victoria is shared amongst Tanzania, Kenya, and Uganda and has tremendous ecological, economical, and cultural significance. Within the lake system, there are several problems, including the proliferation of an invasive weed, water hyacinth (Eichhornia crassipes). Therefore, this study aims to assess several factors that may correlate with water hyacinth proliferation. The specific objectives are (1) to identify possible correlations of water hyacinth density and land use around Entebbe, Uganda, and (2) to identify annual trends in water hyacinth coverage, to better inform policy and conservation efforts. Entebbe has a coastline of six land cover types: flooded vegetation, trees, grasses, …

Agenda: Flpma Turns 40, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

FLPMA Turns 40 (October 21)

The Bureau of Land Management (BLM) administers approximately 245 million acres of our public lands and yet, for most of our nation's history, these lands seemed largely destined to end up in private hands. Even when the Taylor Grazing Act of 1934 ushered in an important era of better managing public grazing districts and "promoting the highest use of the public lands," such use of our public lands still was plainly considered temporary, "pending its final disposal." It was not until 1976 with the passage of the Federal Land Policy and Management Act (FLPMA) that congress adopted a policy that …

Esta investigación estudió los efectos de la sequía en las mujeres de Santa Julia, una comunidad de 60 familias en El Crucero, Managua que estaba una hacienda monocultivo. Santa Julia fue escogida porque su acceso a agua ha sido limitado mucho tiempo, y porque tiene una cooperativa de mujeres que es activa en su gestión. La investigación involucró alrededor de 40 entrevistas y observaciones continuas como participante durante tres semanas en la comunidad. A través de entrevistas que involucraban las historias de las …

Piecemeal Reform Of Trade And Environmental Policy When Consumption Also Pollutes, Mark R. Metcalfe, John C. Beghin

Department of Agricultural Economics: Faculty Publications

We incorporate endogenous (price-responsive) consumption pollution into a dual trade model to assess welfare effects of coordinated trade and environmental piecemeal reform in a small, open and distorted economy. Pollution is generated by production and consumption. Producers control the level of pollution and face incentives to abate both types of pollution. We identify sufficient conditions for welfare-improving reforms of trade and environmental policies. An additional domestic environmental policy instrument must be imposed on exportables because of their supply response to foreign environmental taxes.

How Does Climate Change Affect Agricultural Stability In Southeast Unguja? An Assessment Of The Threats To Agriculture And Food Security From Rising Temperature And Changes In Predictability And Intensity Of Rainy Seasons., Eloise Reid

Independent Study Project (ISP) Collection

The relationship between climate change, agriculture, and food security on the island of Unguja was studied. Informal interviews were carried out in the south-eastern coastal communities of Bwejuu, Paje, and Jambiani in order to gain perspective and awareness of local knowledge concerning changes in climate and it's affects on crop production. Formal interviews were conducted in Stone Town with the Ministry of Agriculture, the Department of Environment, the Sustainable Management of Land and the Environment office, private climate change experts and environmental consultants, and local NGO's to gain insight on what aspects of climate change are most detrimental in the …

Multifunctional Rural Landscapes: Economic, Environmental, Policy, And Social Impacts Of Land Use Changes In Nebraska, Twyla M. Hansen, Charles A. Francis, J. Dixon Esseks, J. Allen Williams Jr.

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The conversion of farmland near cities to other human uses is a global trend that challenges our long-term capacity to provide food, fiber, and ecosystem services to a growing world population. If current trends continue in the United States, the population will reach 450 million by the year 2050. At the same time, an accelerating change in land use will reduce today’s two acres per person of farmland to less than one acre per person. This is scarcely enough to produce food for our domestic population, without any food available for export – even assuming advances in technology. We need …

Action Education In Land Use Decisions: Student Views On Urbanization And Farmland Loss, Mindi Schneider, Charles A. Francis, Dick Esseks

CARI Extension and Education Materials for Sustainable Agriculture

Loss of prime farmland is a serious concern in the United States and around the globe. With rapid urban population increases, the activities and perceived needs of concentrated groups of people result in the swallowing of some of the most fertile lands in this country. Today we have just under 2 acres of productive farmland per person in the United States. Given the current population growth rate due to births and immigration, plus the present rate of farmland loss, World Watch Institute estimates that we will have about 0.6 acres or one-third as much farmland available per person by 2055--a …
