The College of Agriculture Forestry and Natural Resource Management (CAFNRM) at the University of Hawai‘i at Hilo opened its annual Ag Fair Day on April 27, 2018. The fair was very educational for students and visitors alike. There was a lot of information on sustainable agriculture, farming, animal production, bee harvesting, and aquaponics available for everyone by the students of horticulture, animal science, entomology, beekeeping, sustainable agriculture, value-added products and aquaculture.

Garden tours given by UH Hilo ag students are a regular contribution to Earth Day Fair celebrations since the gardens were established in 2009 by former students.

Some 205 students from local pre-K and high schools all over the Big Island toured the gardens by the University of Hawai‘i at Hilo Library Lanai during the celebration of this year’s Earth Day. The gardens were showcased by the Ag230 students of spring 2018. This has been a regular contribution of the class to Earth Day celebrations since these gardens were established in 2009 by former students.

The study—led by affiliate researchers in the UH Hilo College of Agriculture, Forestry, and Natural Resource Management—creates a new, combined process to remove carbon dioxide (CO2) from the atmosphere, produce food and electricity, and reduce deforestation.

Researchers from the University of Hawaiʻi at Hilo, in affiliation with Duke and Cornell universities, have co-authored a study that suggests making croplands more efficient through algae production could unlock an important negative emission technology to combat climate change.

The research, “Integrating Algae with Bioenergy Carbon Capture and Storage (ABECCS) Increases Sustainability,” is funded by a U.S. Department of Energy award and was recently published in the journal Earth’s Future. This funding is a Marine Algae Industrialization Consortium (MAGIC) grant for which Bruce Mathews, dean of the UH Hilo College of Agriculture, Forestry and Natural Resource Management (CAFNRM), serves as the facilitating principal investigator at UH Hilo. Duke University subcontracted the overall project out to multiple institutions, including UH Hilo.

Student and faculty delegates from all 10 campuses of the University of Hawai‘i System joined together for extensive breakout sessions, brainstorming, strategic planning and more.

Tis the season to be ‘susty’! It’s that time of year again when student and faculty delegates from all 10 campuses of the University of Hawai‘i join together for extensive breakout sessions, brainstorming, strategic planning and more. The 6th Annual Sustainability in Higher Education Summit was hosted on Hawai‘i Island at UH Hilo and Palamanui on February 8-10, 2018, for the first time.

At just $10,000 annual net price, UH Hilo students can prepare themselves for a great diversity of careers in the tropical context, whether government or private sector.

The University of Hawaiʻi at Hilo offers one of the top five values in the nation for sustainable agriculture degree programs, according to the online ranking organization CollegeValuesOnline.com. UH Hilo’s bachelor of science in tropical plant sciences and agroecology is ranked fourth of 20 in net price in delivering higher education in sustainable agriculture at an affordable price.

In the ranking, UH Hilo is described as offering “the unique angle of tropical plant sciences for those wishing to labor in tropical zones. At just $10,000 annual net price, students can prepare themselves for a great diversity of careers in the tropical context, whether government or private sector.”

There are new opportunities for Hawaiʻi as an agricultural technology node and as a model for self-reliant food and food production in tropical islands.

On 13-14 November, 2017, I was invited to Honolulu to meet with a delegation from West Sumatra, Indonesia to the East-West Center, the Center for Southeast Asian Studies (CSEAS), and the College of Tropical Agriculture and Human Resources (CTAHR) at the University of Hawaiʻi at Mānoa. The delegation included the governor of West Sumatra, The Hon. Irwan Prayitno, and the former dean of the faculty of agriculture at Andalas University in Padang, West Sumatra, Dr. Ardi.

Dr. Ardi presented a talk on the outcomes 30 years henceforth of the TropSoils Indonesia project conducted by CTAHR, the Indonesian Center for Soils Research, and the U.S. Agency for International Development (USAID) in Sumatra during the 1980s. The project developed sustainable agricultural practices based on integrated nutrient and pest management for resource limited farmers cultivating the regions acidic, low-fertility soils. Overall the economic standing of local residents improved as a result of the project however there are new challenges that need to be addressed for farmers to sustainably intensify their operations and be resilient in the face of climate change and other stresses.

Agricultural modernization is essential to enhance the productive capacity of environmentally-friendly integrative farming systems, farm worker and food product safety, and thereby economic return per unit land area.

Whenever there are allegations of pollution or health risks generated by a medium or large scale agricultural operation there are always people who blanket attack modern agriculture, technology, and corporations. They then often advocate for small farms, production methods of the past, or even worse strongly endorse unverified “miracle” practices.

The problem with looking too much to the past is that it can stifle support for innovation which is key to a resilient food-secure future, and rural economic development. Furthermore in our often romanticized view of small farmers feeding half the world we tend to easily forget that many of these people live on a subsistence diet and frequently suffer hunger and malnutrition due to low and (or) inconsistent yields.

This tour was such a unique experience for me because I didn’t know much about cacao, but now I have a better understanding of what it’s like to process it.

If you are looking for fun and adventure throughout the school year, a club to consider is the Agriculture Club. The Agriculture Club goes on adventures, tours, does projects that the students would like to do, and volunteers with various jobs of interest. Since my sophomore year of college, I have realized how important it is to get involved around the campus, find ways to give back to the community around us, and make long lasting friendships. For that reason, I decided to join the Agriculture Club because agriculture is what I am passionate about and I like to know that the little things that I do, especially volunteering is making a positive impact in our community.

The entire breadfruit tree is a multipurpose and useful resource.

By Damon Adamson.

Belonging to the Moracceae (Fig or Mulberry Family), breadfruit or ‘ulu in Hawai‘i encompasses four primary sub-species: Artocarpus altilis, Artocarpus incisus, Artocarpus mariannensis or Artocarpus communis. Grown in the Hawaiian Islands, as well as throughout the Pacific Basin area. They have been hybridized and many diversities have become prolific. There are currently 24 distinct species of breadfruit. Fruit size, shape, coloration, seeded or seedless, and seasonal ripening are a few of the differences.

There are few annual crops where the farmer can recover costs of high fertilizer and soil amendment inputs required for desired yields coupled with disease and pests in this environment.

On January 9, the Hawaiʻi Island Food Alliance Food Access Working Group, together with The Food Basket, The Kohala Center, and the state Department of Health, hosted a presentation in Hilo by Ken Meter (president of the Cross-roads Resource Center, Minneapolis, Minnesota) that was entitled “Growing Secure Food Systems in Hawaiʻi”. The presentation focused on how the pre-European contact native Hawaiians were completely food independent and that the 1900s resulted in a downward spiral in food production in Hawaiʻi, which was particularly rapid from the 1940s onward. The mid 1960s was the last time that about half the food consumed in Hawaiʻi was produced here. The stated goal was to instigate change that results in greatly improved food independence on the Big Island. There was even quite a bit of discussion regarding community-based food systems and avoiding the cash-based economy, and doing food barter.
