David Wangila recently joined the Clay County Extension Office as the Water and Cropping Systems Educator for Clay, Nuckolls, and Thayer Counties.
Wangila’s interest in agriculture started in Louisiana on the family farm at a young age. All of their food was raised on the farm, and the livestock consisted of cattle, goats, sheep, and chickens.
They also planted corn, dry beans, bananas, collards, kales, and diverse vegetables. This early exposure instilled a deep appreciation for farming and the agricultural sciences.
Wangila was initially trained as a teacher, helping to develop skills and sharing knowledge to a wide variety of students. His dedication for agriculture led him to pursue graduate studies.
He spent eight years conducting research and delivering extension programs focused on managing insect pests in field crops at Louisiana State University, the University of Nebraska-Lincoln, and the University of Minnesota.
Wangila expanded his proficiency in the agricultural industry through roles at Monsanto and Bayer Crop Science, assessing farmer needs, testing products in real-world conditions, introducing new technology and leading training programs for farmers and collaborators.
These experiences reinforced a commitment to linking research with a practical application.
Continuing education has helped with career expansions by a balanced learning approach, which consists of hands-on experiences, mentorship, and formal training, developing expertise in agronomy, extension, and program management.
Wangila led field trials in various countries, training 3,000-plus farmers and extension officers. Conducting research in Louisiana, Nebraska, and Minnesota has strengthened his problem-solving skills and ability to implement effective pest management strategies. These experiences have enhanced Wangila’s ability to design and execute impactful extension programs. He has collaborated with farmers, agronomists, regulatory agencies, and industry experts and has been instrumental in his professional growth.
One particular experience Wangila had in Nebraska was a course studying the Ogallala Aquifer and its role in sustaining agriculture. The challenges of managing this vital resource emphasized the need for sustainable water practices, efficient irrigation, and water conservation to ensure long-term agricultural productivity.
The knowledge Wangila gained strengthened his commitment to promote responsible water management and stewardship through Extension programs. Farmers across Nebraska are adopting innovative techniques to conserve water and enhance crop production, reinforcing his passion for supporting sustainable agriculture in the state through programs.
Wangila says he considers Nebraska home.
“My journey in agriculture and extension work has taken me across different regions, allowing me to gain diverse experiences, but Nebraska has always been special to me. During my time at Louisiana State University for graduate studies, I never imagined that I would find such a deep connection to a place until I came to the University of Nebraska-Lincoln,” he said.
“For more than four years, I conducted research and delivered extension programs focused on pest management in field crops in Nebraska, traveling across counties and working closely with farmers to support their operations. These experiences not only strengthened my professional skills, but also deepened my appreciation for Nebraska’s rich agricultural heritage and the hardworking people who make it thrive.

“My career in the agricultural industry has given me the opportunity to work in various locations, but Nebraska is where I feel most at home. I have built lasting friendships, formed meaningful connections with the farming community, and embraced the welcoming spirit of this state. I am excited and grateful for the opportunity to continue contributing to Nebraska’s agricultural success through research-based extension programs.”
During his free time, Wangila enjoys participating in volunteer work, exploring the landscapes at the parks, local festivals, supporting ag community activities, Husker games, and spending quality time with family and friends. Nebraska has provided a sense of home for Wangila by reflecting the rich culture, strong community bonds, and natural beauty that make up the uniqueness of this state so special.
Wangila feels strongly about delivering innovative, research- based extension programs that empower farmers and strengthen Nebraska’s agricultural and food systems.
