Title: “Fine-Tuning N20 Emission Factors: A case study for a hairy vetch-maize sequence in Argentina.”
Abstract: Measurements of nitrous oxide (N2O) emissions in crop sequences including hairy vetch (HV) and nitrogen fertilization are essential for refining emission factors. Our objectives were to i) determine which nitrogen source (HV or urea) and HV termination time result in lower N2O emissions, and ii) calculate emission factors for the HV/maize sequence. N2O emissions were lower with late termination of HV compared to urea (50 kg N ha-1), and the calculated emission factors for HV residues and urea (<0.12%) were well below the 1% proposed by the IPCC. Utilizing HV could effectively provide nitrogen to maize while minimizing N2O emissions.
Biography: My name is Francisco Cafaro La Menza. I am a PhD fellow from the National Scientific and Technical Research Council (CONICET) at the National University of Mar del Plata, Buenos Aires, Argentina. With a background in agronomy, my research focuses on nitrogen dynamics in the hairy vetch/maize sequence and its effects on nitrous oxide emissions, maize yield, and grain quality. By applying a holistic approach that considers maize productivity and quality, as well as environmental aspects, my goal is to assess management practices related to this crop sequence to assist producers in optimizing their productivity while mitigating greenhouse gas emissions. Recently, I was awarded a training scholarship from the Climate, Food and Farming Network and Global Research Alliance Development Scholarships (CLIFF-GRADS) to collaborate on the project “Mitigating soil GHG emissions in semiarid croplands through improved management” in Zaragoza, Spain. I have been involved in writing and data analysis for two peer-reviewed papers published in international journals, and a few months ago, my first paper as the first author was published in an international journal. Additionally, I have participated in various national congresses, conferences, and seminars, exchanging ideas with researchers and other graduate students, where I have presented and published results from my research.

Title: “Silo bag monitoring system.”
Abstract: Silo bags are a cheaper storage option for grain producers that need to keep their harvest from animals, pests, fungi, and humidity of the environment, all of which is compulsory to maintain a consumption-safe and market-valuable product. This option lacks the monitoring capabilities that a conventional silo provides, like real-time measurement of the grain’s condition through temperature, humidity, and CO2 emissions. This project aims to develop an affordable device and system capable of being easily expanded and implemented in silo bags, potentially increasing profits as it could help with the early detection of unwanted conditions and symptoms of deteriorating matter.

Title: “Utilizing Remote Sensing to Estimate Leaf Biochemical Parameters in Advancing Agricultural Net-Zero Emissions Goals.“
Abstract: Monitoring leaf biochemical parameters is vital for fire prevention and mitigating over-fertilization. Remote sensing can be used to estimate these parameters through leaf reflection. However, existing methods often neglected the multi-angular properties of leaf reflection, impacting the estimation accuracy of biochemical parameters. To address this, we firstly treated multi-angular reflection as noise and established a difference and ratio vegetation index to remove specular reflection, which controls multi-angular reflection. Secondly, we leveraged multi-angular reflection as valuable information and developed a model by integrating the PROSPECT model with a specular function. These methods enhance estimation accuracy and may advance net-zero emissions goals.
Biography: My name is Xiao Li, and I am a PhD student at Northeast Normal University, China, majoring in Cartography and Geographic Information Systems.

Title: “How does the management of dual-use perennial grain systems affect soil health?”
Abstract: Perennial grain systems can help increase soil aggregate stability, which is a soil health indicator that plays a prominent role in building soil structure and storing organic carbon occluded within aggregates and pore networks. The objective of this study was to evaluate the effect of forage defoliation intensity in dual-use perennial grain systems on soil aggregate stability. Soil samples were collected from the 0-20 cm depth in the fourth year after the establishment of Kernza Dual-Use experiments in three locations: Ohio 1, Ohio 2, NY, Minnesota, and Kansas. Trials were planted with the commercially available variety Clearwater Kernza (1504) in a randomized complete block design with four replicates and included four defoliation treatments (forage harvests) at: (i) Summer after grain harvest, (ii) Spring+Summer; (iii) Fall+Summer (iv) Spring+Summer+Fall. Soil wet aggregate stability was determined using nested sieves submerged in water to disaggregate soil through shaking. Oven-dried soils were initially sieved to particle size <8mm, then laid on top of a stack of four sieves with different opening sizes (2000, 500, 250, and 53 μm), ordered bottom-up from the smallest to the largest opening. The stack of sieves was repeatedly submerged into a water-filled bucket for 10 minutes in 2-second intervals. This process determined the proportion of soil-stable aggregate that remained at each sieve size. We found that there were no differences among defoliation treatments over the size and distribution of the aggregates in dual-use perennial grain systems. These results represent an opportunity for growers to sustainably intensify forage harvesting in perennial grain systems while maintaining the productivity potential and health of these systems.

Title: “New sight on the underestimated species diversity and ecology function in soil fauna”
Abstract: Exploring species and their functional diversity is of fundamental importance in biology and ecology. Many earthworm species comprise a wide range of genetic cryptic species, but it remains unclear whether these cryptic species represent distinct ecological entities that differ in traits. The significant differences in multiple traits indicate that the two lineages have different physiologies, supporting their status as cryptic species. The documented variations in morphological and stoichiometric traits of the two lineages/cryptic species call for integration of genetics and ecology for understanding biodiversity and ecological functioning of soil animal species.

Title: “Food-Energy-Water Analysis of the Bipartisan Infrastructure Law.”
Abstract: In light of the Bipartisan Infrastructure Law under the Biden-Harris administration, we must look closely at the initiatives and solutions to bring green industries to the Appalachian region. The Appalachian region has seen over a century of industrialization and depletion of natural resources for economic growth. As these resources were depleted, the struggles in Appalachia continued to grow. With a growing population and an increasing poverty rate, bringing economic growth back to the region is imperative for quality of life. This presentation will cover the Bipartisan Infrastructure Law, projects it has funded, and decisions to be made.
Biography: Hi, my name is Angela Price and I am a master’s student advised by Dr. Jie Zhuang at the University of Tennessee.

Title: “Perception of the impact of climate change and adaptation measures on the livelihoods of fishing communities in the municipality of Marcovia.”
Abstract: Climate change stands as one of the primary challenges confronting humanity, significantly impacting livelihoods. Fishing communities bear the brunt of these effects firsthand. This study delves into the perceptions regarding the impacts of climate change and the adaptation measures on the livelihoods of fishing communities in the municipality of Marcovia in Honduras. Employing a mixed methodology, data was gathered through 133 semi-structured surveys, three focus groups, as well as historical rainfall data and satellite imagery. According to the perceptions within fishing communities, the discernible trends of climate change include rising temperatures, increased precipitation, heightened swell intensity, and the loss of approximately 100 hectares of coastline. The principal impact of climate change in the municipality of Marcovia manifests in the deterioration of local infrastructure, thereby hampering income generation and prompting a surge in climate-induced migration. Direct adaptation measures primarily revolve around mangrove reforestation and infrastructure adjustments to counteract rising sea levels. Indirect measures entail the adoption of new technologies for species identification and the exploration of alternative fishing grounds, thereby exacerbating pressure on fishery resources. Given the anticipated impacts and required adaptation measures, responses necessitate initiatives aimed at alleviating strain on fishery resources and fostering economic diversification. It is recommended that a prospective investigation be conducted into swell intensity and sea level rise to facilitate the relocation of affected populations.

Title: “Unveiling the significant roles of phytohormone 6-benzylaminopurine (6-BA）to empower microalgae for high-salinity wastewater treatment and bioresources recovery.“
Abstract: High-salinity wastewater presents challenges such as osmotic stress and ionic toxicity, inhibiting microalgal biomass conversion. The application of 1 μM 6-BA was found to activate the microalgae’s resistance system, boosting the synthesis and transport of extracellular polymeric substances by coordinating calcium signaling and regulating ion transport and osmoregulatory substance synthesis, leading to increased biomass and flocculation. Additionally, 6-BA enhanced metabolic pathways for carbohydrate, and lipid synthesis, increasing production of polysaccharides, proteins, and lipids. These findings suggest that 6-BA can enhance food safety and clean energy sustainability. The study contributes new insights into phytohormone-assisted high-salinity wastewater treatment and microalgal resource transformation.

Title: “Constructed wetlands for wastewater treatment in urban areas.”
Abstract: Urbanization generates an unprecedented strain on global resources. In the face of consumption and waste production, there is a growing threat to water security. To decrease reliance on modern remediation facilities, constructed wetlands (CWs) are a viable option for natural reclamation. CWs utilize intrinsic biochemical and physical processes that provide several ecosystem services in the urban environment. Aside from water storage and management, wetlands furnish aesthetic, blue-green infrastructure to the surrounding community. With adequate monitoring, CWs are a beneficial tool for carbon sequestration, reducing climate change impacts. Funding for CW projects could be linked to the carbon credit market.

With a perennial cycle of approximately 25 years, Acrocomia emerges as a valuable tool for carbon sequestration efforts, and Argentina has the southernmost populations of this species, representing an ignored genetic resource. My project aims to generate technological and eco-physiological insights to support its cultivation..
Biography: My name is Diego Wassner, I am an agricultural engineer and I work in the Chair of Industrial Crops of the Faculty of Agronomy of the University of Buenos Aires.
I am currently doing my doctorate, with the native palm Acrocomia totai. My professional profile is linked to research into new crops for marginal environments and the development of new crops for bioenergy. In this context I worked with oilseed species such as castor bean, jatropha and currently with Acrocomia. I am particularly interested in research in crop ecophysiology, aimed at generating information that then allows designing agronomic management practices. I strongly believe in the link between the private sector and the university, and in that context I worked on several productive projects for the development of new crops with jatropha and castor bean. Currently I believe that the Acrocomia palm has a high chance of becoming a productive alternative for oils and foods, which also provides environmental and social solutions.

Title: “Oil Seed Crops for Aviation Fuel: Ending the “Food Versus Fuel” Debate.”
Abstract: 2.5% of Global CO2 emissions are contributed from burning of non-renewable fossil fuels in the aviation industry. Other sectors contribute larger amounts of CO2, but the industry facing most challenges meeting net zero emission goals is aviation. Biofuels are a renewable and sustainable alternative capable of reducing CO2 emissions and sequestering carbon. The debate between land use allocation for food production to feed growing populations and fuel crop production has led to the “Food Versus Fuel” debate. Using climate smart agriculture techniques, this perspective proposes the “Food Feeding Fuel” to address land use allocation concerns.

Title: “Time-lag and accumulation effects of extreme precipitation on global vegetation dynamics since the 21st century.“
Abstract: As a major component of global climate change, extreme climatic events are predicted to be increase in duration, frequency, and intensity. However, our knowledge regarding how changes in extreme climatic events may influence vegetation composition and productivity remain insufficient, especially the time-lag and accumulative effects, which have emerged as a crucial yet often overlooked aspect in assessing climate change induced vegetation dynamics. Based on daily precipitation data, we evaluated the temporal effects (time-lag effect and accumulative effect) of the 11 extreme precipitation indices on the global Normalized Difference Vegetation Index (NDVI) in the 21st century.
