revisiting people and nature: protected areas, monitoring technology and socio-ecological interactions
With the ever increasing intensity of the human footprint on Earth, conservation areas stand as the last safeguards of biodiversity in our planet. There are 261,377 official national and state protected areas covering only 15% of the land today. Can you imagine the planet 100, 200, or more than 300 years from now?, Will these management systems still stand?. Can they provide the needed long-term protection to biodiversity?. We want to look deep into these questions and investigate methodological frameworks for better understanding socioecological interactions in community-based conservation areas, wildlife reserves and national parks with the use of geospatial data and field data.
A flagship project is the 'parktrends' project (https://www.parktrends.org). The goal of parktrends is to monitor habitat loss within and around protected areas at local scales, and to report the location of emerging short-term threats to the park managers. The platform serves as a global online interactive geodatabase of public access on the conservation status of protected areas. Habitat loss is detected using multiple optical and radar imagery sources analyzed with machine learning and deep learning approaches. Trends are quantified through the application of spatiotemporal data clustering techniques from sub-annual data obtained from dense time series of earth observation satellites. The user interface and cartographic design is intended to convey complex information in simple, easy-to-interpret terms.
Another main interest of our lab is to investigate the power of dense time-series of remotely-sensed data to understand socioecological interactions in community-based management areas. We try to understand how non-strict community-based nature reserves respond to gradual and sudden socioeconomic crisis (driven by political instability, climate change, diseases, natural disasters, armed conflicts, etc).
Research conducted by our undergraduate and graduate students informs, improves and broadens the methodological approaches used across these two broad themes.

My research lies at the intersection of geospatial science, machine learning, urban ecology, and human dimensions. I integrate GIS, remote sensing, spatial analysis, and ecological and social data to investigate the spatiotemporal dynamics of urban green spaces, avian communities, and human perceptions of urban nature.

Graduate School, Texas Tech University
Skylar Perez studies land degradation and soil biodiversity in the drylands of the Llano Estacado, utilizing geospatial analysis to identify where the region's living soil faces the greatest ecological risk. His research focuses on the intersection of environmental remote sensing and microbiology, mapping belowground fungal and microbial communities that drive ecosystem functioning and dryland resilience. His work results in developing novel design strategies for bioremediation to address soil health and land degradation.
