Effective measurement of seasonal variations in the timing and amount of production is critical to managing spatially heterogeneous agroecosystems in a changing climate. Although numerous technologies for such measurements are available, their relationships to one another at a continental extent are unknown. Using data collected from across the Long-Term Agroecosystem Research (LTAR) network and other networks, we investigated correlations among key metrics representing primary production, phenology, and carbon fluxes in croplands, grazing lands, and crop-grazing integrated systems across the continental U.S. Metrics we examined included gross primary productivity (GPP) estimated from eddy covariance (EC) towers and modelled from the Landsat …

Multifunctionality Of Sown Grassland Is Enhanced By Combining Four Complementary Species, M. Suter, O. Huguenin-Elie, Andreas Lüscher

IGC Proceedings (1997-2023)

We investigated species diversity effects and multifunctionality in an intensively managed grassland. A diversity experiment was set up with monocultures and mixtures comprising Lolium perenne, Dactylis glomerata, Trifolium pratense, and Trifolium repens, and was maintained for three years at 150 kg∙N∙ha^-1∙ year^-1. Ten functions were measured that represented i) forage production (aboveground biomass yield (μ), standard deviation of yield (σ), temporal stability (μ/σ), weed biomass), ii) N cycling (symbiotic-N₂-fixation, N efficiency, NO₃ in soil solution), and forage quality (crude protein content (CP), organic matter digestibility …

The “Sweet Spot” In The Middle: Why Do Mid-Scale Farms Adopt Diversification Practices At Higher Rates?, Kenzo Emiliano Esquivel, Liz Carlisle, Alison Ke, Elissa M. Olimpi, Patrick Baur, Joanna Ory, Hannah Waterhouse, Alastair Iles, Daniel S. Karp, Claire Kremen, Timothy M. Bowles

Fisheries, Animal and Veterinary Sciences Faculty Publications

In the past few decades, farmers and researchers have firmly established that biologically diversified farming systems improve ecosystem services both on and off the farm, producing economic benefits for farmers and ecological benefits for surrounding landscapes. However, adoption of these practices has been slow, requiring a more nuanced examination of both barriers and opportunities to improve adoption rates. While previous research has demonstrated that both individual and structural factors shape farmers' decisions about whether to adopt diversification practices, this study aims to understand the interaction of these individual and structural factors, and how they relate to farm scale. Based on …

Cows V. Capitalists: Visions Of A Post-Carbon Economy, Alison Peck

Journal of Food Law & Policy

I was tempted to entitle this book review something like, "Why the Farm Bill Is the Key to Our Energy Future (Hint: It's Not About Ethanol, Methane Emissions, or Carbon Sinks)." But in addition to being too long to fit across the header of a law review page, such a title would have been slightly misleading. Actually, in Simon Fairlie's view, our future is about ethanol, methane emissions, and carbon sinks - but not in the way our current agricultural policies understand and deal with these subjects.

Journal of Food Law & Policy

Author's Note: This essay is a companion to the essay 'Food Democracy, "which appears in 9 DRAKE JOuRNAL OF AGRICULTURAL LAw 9 (2004). In that essay, the author discussed many of the progressive trends that are helping reshape America's food system. These trends have a common denominator in their reflection of the democratic tendencies of the American populace. The desire of an increasing number of consumers to eat better food and to have access to the information, choices, and alternatives that make better food available are helping drive shifts in food production and marketing. Accompanying these shifts are political and …

A Year In Syntropy: Exploring Syntropic Agriculture, Ajah Eills

College Honors Program

Syntropic agriculture is a form of sustainable agriculture that originated in Brazil around 25 years ago. Although it has since spread throughout Brazil and Australia, there has yet to be a comprehensive study of the driving scientific principles behind syntropy. For my thesis, I conducted literature research and interviews with farmers, with the goal of describing the ecological principles on which syntropy is based, including its primary goal to improve soil health. Much of my thesis contrasted syntropic agriculture with conventional agriculture as practiced in the United States today, but I also explored the differences between syntropic agriculture and other …

Egyptian Women’S Agriculture Contribution; Assessment Of The Gender Gap For Sustainable Development, Noha El Khorazaty

Theses and Dissertations

Women’s contribution to the agriculture sector in developing countries is undeniable, yet they do not have equal access to the resources and opportunities they need to be more productive. Sustainable development entails inclusive and effective management of natural resources, this entails gender equity in agriculture. Bridging the gender gap in agriculture far exceeds the benefits of the individual. According to the latest estimates bridging the yield gap in agricultural productivity could possibly decrease the numbers of undernourished people in the world by around 100 – 140 million people. Sustainable agriculture development and gender equity necessitate policy interventions targeting the gender …

Intellectual Property Rights In The Seed Industry: Barriers To Sustainable Agriculture, Elena A. Filatova

Electronic Theses and Dissertations

The dynamics of the dominant industrial agriculture system restrict the seed industry’s innovative landscape, leading to significant negative consequences including an exacerbation of environmental risks which threaten global food security. This thesis explores how exclusionary intellectual property rights (IPRs) in the context of the seed industry constrict innovation, evolutionary pathways, and opportunities for the implementation of sustainable agriculture methods. To overcome these barriers, the application of an open source framework to seed innovation, specifically through the platform of the Open Source Seed Initiative, is evaluated as a tool for enhancing innovative capacities in seed development while broadening the accessibility and …

Policy Support For Sustainable Development In An Uncertain Future, Hedwig Van Delden

International Congress on Environmental Modelling and Software

Sustainable development requires an approach that values and assesses society, economy and the environment in a holistic and integrated way. When looking at developing countries, the solutions to environmental challenges often go hand in hand with poverty alleviation. Unsustainable land management is likely to lead to environmental decay and losses in ecosystem services, making it hard for subsistence farmers to escape the poverty trap. Policy incentives that focus on long-term development of environmental assets as well as improving livelihoods can therefore create synergies in reaching sustainable development goals. Acknowledging that understanding the socio-ecological system with its inherent feedback processes is …

Assessment Of The Growth In Social Groups For Sustainable Agriculture And Land Management, Pretty Jules, Simon Attwood, Richard Bawden, Henk Van Den Berg, Zareen P. Bharucha, Jacob I. Ricks

Research Collection School of Social Sciences

For agriculture and land management to improve natural capital over whole landscapes, social cooperation has long been required. The political economy of the later twentieth and early twenty-first centuries prioritized unfettered individual action over the collective, and many rural institutions were harmed or destroyed. Since then, a wide range of social movements, networks and federations have emerged to support transitions towards sustainability and equity. Here, we focus on social capital manifested as intentionally formed collaborative groups within specific geographic territories. These groups focus on: (1) integrated pest management; (2) forests; (3) land; (4) water; (5) pastures; (6) support services; (7) …

Design And Testing Of A Multi-Depth Soil Temperature Sensor Array Intended As A Candidate Irrigation Scheduling Tool, Lillian Glaeser

Biological and Agricultural Engineering Undergraduate Honors Theses

A crucial measure in the advancement of water conservation and sustainable agricultural strategies is increasing efficiencies of irrigation systems. Because of the lack of availability of affordable, durable, and scalable soil moisture monitoring devices, this thesis proposes a low-cost, multi-depth soil temperature sensor array as a candidate for monitoring soil moisture content and guiding farmer’s irrigation scheduling. Propagation of diurnal temperature waves through soil is dependent on the thermal diffusivity of the soil, which can be determined by examining temperature waves at different soil depths. Thermal diffusivity is dependent on several factors, though, in undisturbed soil, water has the largest …

Implementing Demonstration To Promote The Sustainable Farming Practice Of Using Cover Cropping Systems, Qingren Wang, Christian F. Miller, Shouan Zhang

The Journal of Extension

Use of cover cropping systems has multiple benefits for agriculture. To convince vegetable growers to adopt such systems, we applied a field demonstration in which we grew selected cover crops during the off-season and then tomatoes. We focused on implementation of a science-based demonstration design and attended to the usefulness of the demonstration and audience timing preferences. As a result, growers grasped the advantages of growing cover crops and, consequently, have extensively adopted cover cropping systems, thereby applying a critically important practice for crop management and agricultural sustainability. Our method and findings can help Extension educators better implement programs to …

Comparing Outdoor Vertical Hydroponic Farming Systems And Conventional Hydroponic Farming Systems With A Focus On Efficiency, Itohan A. Edokpolo

Theses and Dissertations

Combining hydroponics and vertical farming creates unique growing system that reduces the need for excessive water and land usage to grow more food. The main critique of this system is the high cost of setup, run and the potential drawbacks of shading on plant productivity. Five species were grown in three hydroponic designs known as horizontal, vertical and a-frame. The designs were compared in terms of productivity, space and energy. Results showed variability in plant productivity in the designs can be attributed to other factors other than light. Differences in species performance were seen in response to different factors. Horizontal …

How Do Farmers Experience Agroecology In Rural Communities Of Northern Ecuador?, Neil Michael Ayala Ayala

Latin American Studies ETDs

Agroecology, a concept in continuous evolution embraces science, practice and sociopolitical aspects. Its meaning is gaining space of debate and global interest as an alternative for building sustainable food systems and resilient communities, not only from the environmental perspective, but from all the dimensions of sustainability. The Andes region is recognized for its agrodiversity and for its history of agricultural activity; nevertheless, the effects of unsustainable agricultural practices inspired in the principles of the so called “Green Revolution” are evident. Conventional agriculture has decreased the capacity of resilience of the agroecosystems and their associated communities. Agroecology is often perceived as …

Developing Alternative Forage Production Strategies For Enhanced Environmental And Economic Resilience On New England Dairy Farms, Samantha Glaze-Corcoran

Doctoral Dissertations

Cover crops are prized for their array of well documented and widely respected ecosystem services. Cover crops are an intrinsic part of building and sustaining soil health and thus the long term productive capacity of agricultural soils. However, effective cover crop adoption on New England dairy farms is lacking, and the benefits of traditional cover crops may be somewhat mismatched to the needs of dairy farms. Harvesting winter hardy small cereal grains for forage can provide practical incentive to farmers to incorporate effective cover crop management as well as provide an economic benefit in the form of additional on-farm forage …

Carbonatites As Rock Fertilizers: A Review, James Mc Jones, Frédérique C. Guinel, Pedro M. Antunes

Biology Faculty Publications

Rock fertilizers are geological resources used in agriculture for their nutrient content, but slow weathering rates hinder their effectiveness. Carbonatites are igneous rocks made mostly of carbonate minerals with a relatively high weathering rate and often containing nutrient-bearing accessory minerals (e.g., apatite and biotite). Despite evidence supporting their potential as rock fertilizers, a comprehensive review of such data is missing in the literature. Furthermore, when studies on agricultural uses of carbonatites exist, they typically center on applied research aspects (i.e., “does it work?”) rather than on basic research aspects (i.e., “how does it work?”). Here we evaluate the applicability of …
