Professor H. Douglas Gross (1924-2022), was a distinguished figure whose expertise and vision significantly shaped the early understanding and promotion of Integrated Aqua-Vegeculture Systems. His contributions as a consultant and advocate were invaluable during a critical period of IAVS development.
From 1987 to 1994, Dr. Gross served as a principal consultant to the iAVS Research Group. Drawing upon his profound knowledge as Professor Emeritus in Crop Science and International Agricultural Development at North Carolina State University (NCSU), he brought a wealth of practical and academic experience to the initiative. His skills in understanding plant physiology, soil science , and, crucially, the challenges of agricultural development in diverse global contexts, were instrumental.
In 1988, leveraging his affiliation with the NCSU Office of International Programs, Dr. Gross authored the influential summary, “The Integrated Aqua-Vegeculture System.” This document was more than a technical overview; it was a compelling piece of advocacy born from his “firm conviction that the technique is worthy of more widespread field testing.” He eloquently articulated the potential of iAVS, describing it as a “tightly-coupled, virtually symbiotic system” capable of producing significant fish and vegetable yields with remarkable water efficiency. His summary highlighted its capacity to enhance food security, improve nutrition, and create economic opportunities, particularly in resource-limited regions.
Dr. Gross’s expertise helped bridge academic research with practical global needs, lending crucial credibility and a development-focused perspective to the iAVS initiative. His work underscored the system’s potential for sustainable food production, a theme consistent with his lifelong dedication to agricultural science and improving livelihoods worldwide.
Beyond his immense professional contributions, Dr. Gross embodied an extraordinary and enduring spirit. At the age of 93, he fulfilled a 75-year-old dream by making his first parachute jump – a remarkable testament to his tenacity, adventurous nature, and zest for life. This same determined spirit undoubtedly fueled his dedication to innovative solutions like IAVS, pushing for their recognition and application.
Professor Douglass Gross leaves a legacy of impactful service, scientific rigor, and forward-thinking advocacy. The IAVS community remembers him with immense gratitude for his foundational contributions, his unwavering belief in sustainable solutions, and the inspiring example of his multifaceted life. His work helped lay crucial groundwork for future advancements in integrated food systems, and his indomitable spirit continues to motivate.
My most vivid memory of Doug was during my first trip to Egypt in which he accompanied me. Overall it was very interesting,especially the Cairo Museum albeit that the traditional tourist landmarks were underwhelming. So, one evening we decided to partake in the local cuisine. We went deep into the off-the-tourist map and found a neighborhood restaurant on the corner of a two very narrow ‘streets’. There was something on the menu that was translated for us into “meat’, so we unsuspectedly ordered that. I’ll never forget the sensation or the look on Doug’s face as we took the first bite. I’m fairly certain it was camel meat … but which part? Sphincter? We rinsed our mouths with tepid ‘beer’ and left with a grin at the staff (and in shock). That memory remains as vivid today as it was 37 years ago. In contrast, we subsequently visited several countries in the western Sahel where it was soon suggested that we try a local ‘delicacy’ known as Agouti. It is a huge ‘bush rat’ looking like a huge Beaver or Nutria without a paddle-like tail. The very best tasting, sweetest meat I’ve ever eaten bar none (Oryx tenderloin comes close). So at every restaurant I visited after that I would always ask for Agouti and many would have it. And as you entered many of the villages it was not uncommon to see young boys standing at the edge of the road holding up Agouti by the tail for sale. They would chase them down as a group on foot and club them into someones dinner. Anyway, never try the ‘meat’ in a Cairo diner and always order the Agouti.
