Organic Circularity: From Crop Waste to Compost
Bonhotal, Jean; Schwarz, Mary (2025-07-21)
The poster and the video both describe how crop waste can be used to create compost to grow more crops, hence improving soil and contributing to a circular economy.

The Spatial and Temporal Distribution of Urban Vegetation Phenology by Local Climate Zone and Urbanization Level
Liu, Ruihan (2025-05)
This report is for a capstone project for Cornell MPS, concentration Geospatial Applications, to illustrate mastery of a complex geospatial analysis. It used a wide variety of techniques and tools. The project investigated an important topic in the context of the urban environment under climate variability: the spatial-temporal distribution of vegetation phenology in Beijing, focusing on the impacts of local climate zones (LCZ) and urbanization levels. Using MODIS MCD12Q2 data, we analyzed the start of season (SOS), end of season (EOS), and length of season (LOS) across different urbanization gradients and LCZs. Results reveal that urbanized regions exhibit earlier SOS and longer LOS, while natural areas have a later EOS and shorter LOS. LCZs with lower density buildings tend to have a more extended growing season. These findings underscore the significance of urbanization and LCZ in shaping vegetation phenology, providing valuable insights into climate change adaptation and urban ecological management.
Traminette: Cold-Climate Adaptability and Sensory Identity
Zhang, Yu (2025-05)
Traminette, a hybrid grape cultivar developed through a cross between Gewürztraminer and Joannes Seyve 23.416, has emerged as a benchmark for sustainable viticulture in cold-climate regions. Combining high aromatic potential with exceptional resilience, it offers a unique model for both ecological and market adaptability. This poster presents a comprehensive study that integrates a cross-regional viticultural comparison (New York’s Finger Lakes and Northern China’s Heilongjiang) with a controlled sensory evaluation that contrasts Traminette with its vinifera parent, Gewürztraminer. The goal is to contextualize Traminette as a solution for climate-resilient wine production while examining its distinct sensory identity.
Comparing Traditional Turfgrass Lawns with Native Lawns: An Ecological and Economic Perspective
Tsignadze, Maia (2025-05)
Urban landscapes across the United States have long been dominated by traditional turfgrass lawns, which are resource-intensive and offer limited ecological value (Milesi et al., 2005; Robbins & Birkenholtz, 2003). In contrast, native lawns—composed of regionally adapted, low-growing plant species—are gaining attention for their potential to enhance urban sustainability through improved biodiversity, water conservation, and ecosystem services (Tallamy, 2009; Nassauer et al., 2014). This project compares the ecological and economic impacts of traditional turfgrass lawns with native lawns, focusing on establishment and maintenance costs, biodiversity support, water use efficiency, carbon sequestration, and overall ecosystem health. A comparative analysis methodology was employed, integrating secondary data collection, cost comparison, and environmental impact assessment. Data were gathered from industry reports, environmental organizations, and a case study of the Cornell Botanic Gardens Native Lawn Demonstration Project to evaluate key indicators such as chemical inputs, maintenance requirements, and ecosystem services. While turfgrass lawns are often preferred for their aesthetic appeal and cultural familiarity, they are increasingly recognized as ecologically and economically unsustainable in many regions (Polsky et al., 2014). Results indicate that native lawns offer substantial long-term cost savings, greater biodiversity support, and reduced environmental harm due to lower chemical and water input requirements. By evaluating and comparing both systems, this study supports sustainable landscape design and urban planning and promote wider adoption of native lawns in residential and public spaces.
