New Office Supports Maine Climate Action, Parker Gassett, Ivan Fernandez
New Office Supports Maine Climate Action, Parker Gassett, Ivan Fernandez
Maine Policy Review
Expanding and expediting access to climate change information can improve collective action outcomes. Accordingly, the Maine Climate Action Plan called for the creation of an information-coordinating hub, to enable effective and efficient use of climate information in Maine’s climate change response. To aid that need, the University of Maine created the Maine Climate Science Information Exchange (MCSIE) office as a gateway to information about climate-relevant research, the scientists conducting that research, and the most recent data and applied science efforts relating to Maine’s climate change strategies. The office was established in 2023, after a year of developing prototypes of the …
Novel Pilot Development Of A Closed-Loop Sustainable System Between Biogas Renewable Energy, Distilling, And Aquaculture By Vermiculture Of Stillage Wastes, Samuel C. Kessler
Novel Pilot Development Of A Closed-Loop Sustainable System Between Biogas Renewable Energy, Distilling, And Aquaculture By Vermiculture Of Stillage Wastes, Samuel C. Kessler
The Cardinal Edge
This study provides a mixed-methods approach in analyzing a potential closed-loop system between renewable biogas production from anaerobic digestion, vermiculture production, aquaculture production, and organic wastes with a particular focus on stillage wastes. Such system may hold significant promise for significantly reducing organic carbon and methane emissions from its components, and should be assessed for such. The 2021 IPCC report essentially identified methane reduction as the single fastest way to slow global warming (IPCC, 2021), making the study and implementation of methane-reducing systems and supportive policy for them critical. Knowledge gaps to implementing this system were qualitatively identified as disconnect …
Data-Driven Agriculture For Rural Smallholdings, Kerry Taylor, Martin Amidy
Data-Driven Agriculture For Rural Smallholdings, Kerry Taylor, Martin Amidy
Journal of Spatial Information Science
Spatial information science has a critical role to play in meeting the major challenges facing society in the coming decades, including feeding a population of 10 billion by 2050, addressing environmental degradation, and acting on climate change. Agriculture and agri-food value-chains, dependent on spatial information, are also central. Due to agriculture's dual role as not only a producer of food, fibre and fuel, but also as a major land, water and energy consumer, agriculture is at the centre of both the food-water-energy-environment nexus and resource security debates. The recent confluence of a number of advances in data analytics, cloud computing, …

Rain Rituals As A Barometer Of Vulnerability In An Uncertain Climate, L. Jen Shaffer
Rain Rituals As A Barometer Of Vulnerability In An Uncertain Climate, L. Jen Shaffer
Journal of Ecological Anthropology
Researchers and aid agencies, seeking to improve their understanding of local climate change responses, adaptation, and vulnerability, frequently interact with communities around the world who strongly emphasize their religious beliefs and practices. Dismissal and misunderstandings of these local perspectives can slow assessments of local climate vulnerability and development of adaptive capacity. In this paper, I show how analysis of rain ritual failure exposes the multiple stressors Ronga communities in southern Mozambique face, and as such, serves as a proxy measure for climate vulnerability at the local level. Oral histories and targeted interviews with participating elders, local chiefs, and community members …
Personal Meaning Mapping As A Tool To Uncover Learning From An Out-Of-Doors Free-Choice Learning Garden, Deborah L. Bailey, John H. Falk
Personal Meaning Mapping As A Tool To Uncover Learning From An Out-Of-Doors Free-Choice Learning Garden, Deborah L. Bailey, John H. Falk
Research in Outdoor Education
Garden-based learning (GBL), a form of outdoor education contextualized and framed within unpredictable and real-world learning environments, is ideally suited to the teaching of science. However, the vast majority of GBL educational research has utilized a cognitive and positivist research paradigm, one that artificially restricts the investigative lens. The goal of the larger project from which this paper was drawn was to develop a better understanding of how youth perceived a garden experience. This paper shares the affordances and constraints of the constructivist framework utilized and the primary measurement tool, Person Meaning Mapping (PMM). Despite some inherent limitations, the PMM …
A High-Altitude Balloon Platform For Determining Regional Uptake Of Carbon Dioxide Over Agricultural Landscapes, Angela M. Bouche
A High-Altitude Balloon Platform For Determining Regional Uptake Of Carbon Dioxide Over Agricultural Landscapes, Angela M. Bouche
DePaul Discoveries
Interactions between the biosphere and atmosphere are an important part of the global carbon cycle, and quantifying the carbon dioxide exchanges between them is helpful in predicting the uptake of carbon dioxide from anthropogenic sources by the biosphere in the future. In the Midwestern United States, agricultural systems cover a large part of the landscape, so understanding their role in influencing the global carbon budget is crucial as anthropogenic sources of carbon dioxide grow larger. Carbon dioxide exchanges can be measured by eddy covariance at the ecosystem level (bottom-up approach) or regionally by inversion techniques (top-down approach). Here we describe …
Agriculture In A Water Scarce World, Allison Roberts, Amjad Assi, Bassel Daher, Men Li
Agriculture In A Water Scarce World, Allison Roberts, Amjad Assi, Bassel Daher, Men Li
Student Papers in Public Policy
According to the McKinsey report (2009), the world is facing a water scarcity challenge where agriculture is its predominant consumer. It accounts for approximately 3100 billion m3, or 71 percent of global water withdrawals today, and is expected to increase to 4500 billion m3 by 2030. This increase is due to a number of factors: growing population and the ever growing necessity to cater for its food needs, economic growth, the variability of precipitation trends and increase in global temperatures. In addition to the increase in water scarcity, the agricultural sector faces an enormous challenge of producing …
Effects Of Global Climate Change On Nigerian Agriculture: An Empirical Analysis, Apata T. .G
Effects Of Global Climate Change On Nigerian Agriculture: An Empirical Analysis, Apata T. .G
CBN Journal of Applied Statistics (JAS)
This paper presents an empirical analysis of the effects of global warming on Nigerian agriculture and estimation of the determinants of adaptation to climate change. Data used for this study are from both secondary and primary sources. The set of secondary sources of data helped to examine the coverage of the three scenarios (1971-1980; 1981-1990 and 1991-2000). The primary data set consists of 900 respondents’ but only 850 cases were useful. This study analyzed determinants of farm-level climate adaptation measures using a Multinomial choice and stochastic-simulation model to investigate the effects of rapid climatic change on grain production and the …

Use Of Artificial Enclosures To Determine The Survival Of Rana Pipiens Larvae In Upper Midwestern Agricultural Ponds, Joshua M. Kapfer, Mark B. Sandheinrich, Melinda G. Knutson
Journal of the Iowa Academy of Science: JIAS
Amphibians in the upper Midwest use agricultural ponds for breeding. Unfortunately, the risks (both direct and indirect) associated with using these ponds are poorly understood in both amphibian adults and larvae. In order to quantify these risks, we performed a comparison of larval survival rates between agricultural and natural ponds in southeastern Minnesota during the spring and summer of 2001. During this time, larval survival was observed in Rana pipiens tadpoles raised through metamorphosis in enclosures placed in agricultural and natural ponds. In addition, we measured the levels of nutrients commonly linked with agricultural ponds (i.e., ammonia, total phosphorous, and …
