Knights Landing Environmental Health Project
Research | Advocacy | Community

Executive Summary
The Knights Landing Environmental Health Project (KLEHP) is a collaborative, community-driven initiative bringing together transdisciplinary academics, local organizations, and rural residents to directly address environmental health risks. We empower the Knights Landing community to understand and mitigate these risks by facilitating community-based participatory research, training promotoras and student researchers, conducting public health studies, and translating findings into actionable prevention strategies, ultimately driving environmental justice for a healthier future.
Background
The KLEHP began in 2016 as a student- and community-led initiative, driven by a commitment to environmental justice. Dr. Aranda's graduate research in Knights Landing revealed residents' acute exposure concerns, complemented by his colleague's sampling that detected carcinogens. After graduating, Alfonso earned a faculty role at Sacramento State University to re-establish and expand this vital project. Today, the KLEHP is a robust collaboration between CSUS, UC Davis, local environmental justice organizations and Knights Landing residents, working to translate research into tangible community health improvements.Click here for additional resources, including team bios and funding info
Projects and Results
We are a community-responsive research team consisting of several projects. Altough our main focus is environmental public health, our projects span multiple topic areas. See below for summaries and infographics of our work:
Through strong partnerships with UC Davis MPH students and the Yolo County Public Health Division, our team has developed a comprehensive understanding of health concerns and medical service challenges in Knights Landing. Our research, including interviews with healthcare leaders and analysis of public health assessments, revealed a significant need for improved transportation to central health facilities and expanded community health promoter programs. We have also documented disparities in healthcare access and utilization based on race/ethnicity and income. See below:
Our research in environmental health focuses on preventing agrochemical exposure through direct environmental sampling and analysis of pesticide application data. We utilize advanced mapping and modeling techniques to understand pesticide distribution and movement, aiming to collaborate with local stakeholders to reduce environmental contamination. Simultaneously, we prioritize community knowledge and work to ensure access to clean water for all residents, including those relying on unregulated private wells.
Introduction:
The Knights Landing community garden project, initially conceived by the Pueblo Unido youth group but stalled by irrigation issues, was revived by the KLEHP. Recognizing its immediate community benefit, our promotoras and student teams procured funding to enable its design, construction, and community activities like cooking classes, evolving into a KL One Health Center committee. This garden's identity, from name to plants, is shaped through a continuous community-driven process, ensuring every voice is heard, creating a space that truly reflects and helps realize the aspirations of Knights Landing residents.
Project Goals:
To develop a community garden in Knights Landing that provides fresh food and recreational space while serving as a platform for youth to engage in community service and gain hands-on skills.
Garden Design Proposals:
Designed by UC Davis student Ana Guerrero, based on community ideas, this garden plan provides a valuable vision for growing fresh produce and creating recreational space. Initial funds will primarily established the main water line and drip irrigation system to supply the garden. Additional resources provided fencing, walking paths, shade, tools, lighting, sheds, waste containers, raised beds, starters, a compost system, and youth-built benches.
Our Current Garden:
Beyond cultivation, the garden is a vital social and recreational hub, offering outdoor seating for workshops and picnics, and tranquil paths for reflection and interaction. Community partners organize activities promoting exercise and healthy eating, while Empower Yolo collaboration assigns garden responsibilities to youth. This mentorship will foster critical thinking and leadership skills, aiding their educational and career development.
