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.

One of the major challenges was that there was no real discussion of the biophysical and social constraints that would need to be overcome. When I pointed out that Native Hawaiians largely farmed the fertile alluvial valley soils and sweet spot uplands where rainfall was sufficient to grow sweet potato, etc., but not so excessive to result in heavy nutrient losses (soil fertility depletion) by leaching I was told that one can use soil restorative rotations of certain (undefined) legumes to make the former sugarcane lands of the high rainfall Hilo-Hamakua Coast productive for food crops. I politely implied that this thinking was delusional and backed up by scientific evidence regarding the very limited potentials of biological uplift of nutrients and nitrogen-fixing green manures in high rainfall zones with heavily leached soils.

On the infertile upland soils in high rainfall zones the Native Hawaiians practiced slash and burn agriculture with short annual (usually one to two crop) cropping periods and very long fallows or plantings of tree crops such as breadfruit. Long fallows are not practical in the modern era. Neither is expansion of wetland and gulch taro production as most of the fallow areas are now zoned for conservation to protect wetland habitat and wildlife. In this regard it is interesting to note that the waterfowl of concern seemed to survive when Native Hawaiians and then immigrants from Asia cropped the valleys and gulches wall to wall with taro, had extensive aquaculture, and later also grew rice. Furthermore, it is problematic that most of the sweet spot uplands with high soil fertility that were formerly used largely for sweet potato cultivation are presently under the tropical grass pastures of the large privately held ranches. These lands are unlikely to be converted to row-cropped field systems and would require major irrigation infrastructure development to avoid the risk of crop failure during droughts that have become more frequent with climate change.

There is a reason that most of the former rain-fed sugarcane lands on the Big Island are now used for perennial pasture and tree crops that are not as nutrient demanding in terms of soil fertility as most annual agronomic and vegetable crops. In a large part it’s that there are few annual crops where the farmer can recover the costs of the high fertilizer and soil amendment inputs required for the desired yields coupled with the multitude of introduced disease and pest problems in this environment. To make matters worse, applied nitrogen and potassium fertility is rapidly leached away necessitating frequent reapplication. Due in part to the soil fertility constraints and cost of the available lands and labor we are not going to be growing staple crops in major quantities anytime soon.

Some keys to improving food independence are as follows: 1) developing viable strategies to recover essential plant nutrients from the human waste stream in order to reduce dependence on imported fertilizers, 2) designing novel controlled-release and extender fertilizers such as those based on colloidal ion exchangers (exchange fertilizer technology) for more efficient nutrient delivery in the humid tropics, 3) encouraging and facilitating state and federal professionals in horticulture and agronomy to conduct the scientifically non-glamorous but essential work of germplasm evaluation that includes crop nutrient use efficiency and pest-disease resistance parameters, 4) improving the opportunities for people interested in becoming farmers to have relevant training on commercial scale farming practices, and 5) educating people on the multifaceted components of successful rural entrepreneurship.

Bruce Mathews is dean of the College of Agriculture, Forestry and Natural Resource Management at UH Hilo. His areas of research are plant nutrient cycling and soil fertility; assessment of the impact of agricultural and forestry production practices on soil, coastal wetlands, and surface waters; and nutrient management practices for pastures, forests, and field crops in the tropics (learn more about his research). He received his bachelor of science in agriculture, with high honors, from UH Hilo in 1986. He received his master of science in agronomy from Louisiana State University and his doctor of philosophy in agronomy, with a minor in animal science, from the University of Florida. Contact.

UH Hilo researchers believe the biggest challenge that Hawaiian tree species will face in the future is how quickly they will get water, especially in higher temperatures.

Scientists at the University of Hawai‘i at Hilo are tackling climate change issues with numerous research projects focusing on a variety of target areas ranging from testable theories to the collection of data. In many of the projects UH Hilo faculty, graduate students, and island resource managers are working together to conduct important collaborative research focused on building the community’s ability to adapt to future climate and land use changes.

Professor of Biology Becky Ostertag leads two such projects—a long-term forest research project with many partners across the Hawaiian islands, and a separate research study with graduate student Joanna Norton. Both projects link established and potential problems related to our forests to further help scientists and island resource managers understand the effects of climate change on the island’s environment.

Forest studies

Ostertag’s project, called the Hawai‘i Permanent Plot Network or HIPPNET, is the deployment of permanent research sites across Hawai‘i that track various factors in Hawaiian forests—the birth and death of trees, growth rates, species and so forth—all monitored with the data compiled together like an information packet. This comprehensive history helps to evaluate how Hawaiian species respond to climate fluctuations and allows researchers to make predictions about how Hawaiian forests will do with long term climate change. The collected field data relates to climate change by linking factors such as minimum and maximum temperatures, rainfall, solar radiation, soil moisture and wind speed.

The biggest issue that Hawaiian species will face is how quickly they will get water, especially in higher temperatures, Ostertag explains.

“Water is going to become an important issue with climate change,” she says.

Prof. Ostertag earned her bachelor of arts in biology from Carleton College in Northfield, MN, and later received her doctor of philosophy in botany from the University of Florida in Gainesville. At UH Hilo, she teaches, leads her own research projects, and chairs and advises students in the Tropical Conservation Biology and Environmental Science graduate program as she is with Joanna Norton.

Ostertag’s HIPPNET project is a collaboration with the Institute of Pacific Island Forestry of the USDA Forest Service, the University of California-Los Angeles, and UH Mānoa, and has received funding from the National Science Foundation, the Pacific Southwest Research Station of the USDA Forest Service, and the Pacific Islands Climate Science Center based at UH Hilo.

Additional funding from the Pacific Islands Climate Science Center allows Ostertag and fellow researchers to investigate sapflow, the rate in which trees take up water.

Albizia studies

Norton’s research is part of the UH Hilo collaborations with the Pacific Islands Climate Science Center that link graduate students, agency and community natural resource managers and faculty to focus on today’s challenges related to climate change.

Norton’s project focuses primarily on alternative agricultural methods investigating the use of an invasive albizia tree species (Falcataria moluccana), found here on Hawai‘i Island, as an alternative fertilizer.

Agriculture is one of the biggest influences in climate change—carbon dioxide and methane gas are contributors, however nitrous oxide is the biggest component.

“It is a much more powerful greenhouse gas and it’s coming out of agricultural fields which makes it reactive,” Norton explains.

Oftentimes agricultural gas emitted from the fertilizers is not mentally registered because it is considered routine and regular agriculture.

Norton’s research project includes the collection of albizia trees which are chipped, composted and then spread across agricultural lands ranging from Hilo to Kohala. After the composted albizia trees are dispersed across these agricultural plots, Norton will compare it to chemical fertilizers by analyzing differences in plant growth, soil and plant nutrient levels, and soil water holding capability.

Norton originally hails from Washington, DC, but has spent half her life in Hawai‘i. She earned a bachelor of science in biology from UH Hilo, and is now earning a master of science at the university’s Tropical Conservation Biology and Environmental Science program.

She says she came back to school after being in the “work world” and continues to work with various employers conducting agricultural experiments. Her research project is similar to her work, however, she is given the freedom to design the agricultural question.

“Here at UH Hilo, I am learning the latest research on agriculture, invasive species, and climate change, which gives my work context,” she says. “I’m learning how to ask and answer questions in a scientific way as well as learning the logistics and planning that goes into a research project.”

By designing and implementing her own research project, Norton is gaining more than just answers to untested questions—she is learning useful and applicable techniques and information that will help her understand climate change and how adjustments might be made to adjust or prevent these fluctuations.

Partnerships and collaborations

Norton’s agricultural investigations also interfaces with the HIPPNET forest research project, which is in collaboration with a worldwide network called the Center for Tropical Forest Science—projects involved with this network use similar tools for data analysis, which allows for cross-site studies. These cross-site studies show how Hawaiian forests compare to other tropical forests and some temperate forests across the globe.

The UH Hilo HIPPNET project is part of The Center for Tropical Forest Science – Forest Global Earth Observatory (CTFS-ForestGEO), a global network of forest research plots and scientists dedicated to the study of tropical and temperate forest function and diversity. The multi-institutional network comprises over 60 forest research plots across the Americas, Africa, Asia, and Europe, with a strong focus on tropical regions. CTFS-ForestGEO monitors the growth and survival of approximately 6 million trees and 10,000 species. Click photo to enlarge. Source.

This ability to compare Hawaiian forests and species with the outside world influences Norton’s project. Norton’s project compares a variety of factors, one of which includes the albizia tree fertilizer’s ability to retain water. The HIPPNET plot project’s observations and data analyses show that the water intake rate of Hawaiian tree species means there is a need for alternative fertilizer options. Norton is researching and testing one of many purposed alternative methods.

Norton’s work is funded by the Pacific Islands Climate Science Center, which works in conjunction with managers and scientists from a collaborative agency called the Big Island Invasive Species Committee. Norton’s partnership with BIISC—part of the Manager Climate Corps—is to ensure that her research is applicable to the community—invasive species have become a hard-pressing problem on the island because the invaders force competition between native and invasive species for limited resources and nutrients.

Norton looks forward to continuing her work in agricultural research after graduation. She wants to combine her “on-the-ground skills with the expertise and scientific perspective.”

“Whether my work is primarily in agriculture, land conservation, or climate science, I hope to use my positions to take a multidisciplinary systems approach that is concerned with the entire situation,” she says.

The scientists are developing a method known as Incompatible Insect Technique, using a bacteria to prevent male mosquitoes from reproducing.

To protect Hawaiʻi’s unique, imperiled native birds, researchers from the University of Hawaiʻi at Mānoa and UH Hilo are teaming up with the Department of Land and Natural Resources (DLNR) and the U.S. Fish and Wildlife Service to adapt a “birth control” method used across the U.S. mainland to control mosquitoes. The scientists are taking the first steps to adapt a safe, targeted and efficient mosquito control method known as Incompatible Insect Technique to reduce the population of the disease-carrying mosquitoes that harm native birds in Hawaiʻi.

Incompatible Insect Technique acts like a birth control method for mosquitoes and it has already been adopted and proven successful around the country and the world to protect human health and quality of life. A similar method has been used in Hawaiʻi for decades to control fruit fly pests which are harmful to local agricultural products.

Mosquitos are a nuisance and a hazard both to people and to Hawaiʻi’s native birds, which are in danger of extinction from decades of habitat loss, predation and diseases like avian malaria and avian pox.

“We are already seeing the loss on Kauaʻi of the safe havens of higher elevation forests for our native birds,” says Cynthia King, an entomologist with DLNR. “Mosquito-spread diseases are decimating bird populations and if we do nothing we could lose several more species in the next 10 years.”

Just one of the six types of mosquitoes found in Hawaiʻi harms native birds—Culex quinquefasciatus. Scientists and conservationists are working together to use a bacteria that is naturally-occuring in fruit flies in Hawaiʻi. It is called Wolbachia bacteria, and the research, which will be done in controlled laboratory settings, involves giving the male mosquitoes a different strain of the bacteria than is normally found in them, to prevent them from producing offspring. To reproduce, most mosquitoes carry a type of this Wolbachia bacteria in their system. When male mosquitoes with the different strain of the bacteria try to mate with females, there are no offspring.

“The process for mosquitoes is very similar to techniques that have been used for many decades in Hawaiʻi to control pest fruit flies for the benefit of agriculture,” says King. “It doesn’t eradicate the insect, but helps to safely reduce the population on a landscape scale without the use of pesticides and without harming any other species.”

Climate change is on everyone’s radar and the need to figure out the environmental impacts caused by human consumption has been pushing the scientific community. Several research projects stimulated, conducted, and maintained at the University of Hawai‘i at Hilo are working on this challenge by focusing on innovative methods and ideas that contribute to that field of study and expertise.

There are various research projects around campus that allow students and faculty to work side by side on incredible climate change studies.

Patrick Hart, professor and chair of biology at UH Hilo, has kick-started a few projects in his department that have been ongoing for years.

“We are in a very key place for looking at climate change issues and looking at issues related to biodiversity,” says Hart. “We have this extinction crisis going on in Hawai’i while being in this incredible region of diverse plant and animal species which is fascinating. This dendrochronology research is instrumental in how we will predict future climate shifts on all levels along with being able to prepare for these changes while preserving some of our world’s most amazing plants and animals.”

The dendrochronology project Hart refers to is the study of core samples from indigenous trees on the island of Hawai‘i. His tree ring research project has been in production for almost ten years.

The current research is made possible through the National Science Foundation Centers for Research Excellence in Science and Technology or CREST program now in its fourth year at UH Hilo and funding from the Pacific Islands Climate Science Center.

Tree rings

Various graduate students have worked on this research alongside Hart, contributing to substantial strides in the science community. Shea Uehana is the current graduate student involved on the project—before him, Kainana Francisco and Tishanna Ben also partook in this inquiry.

Tree rings are used in a variety of ways—they are used to calculate the age of a tree, climate conditions throughout the lifespan of the plant, health of the soil, previous precipitation, etc. The rings on a tree develop at the end of an annual year in the life of the plant and tends to be produced in trees that experience a range of the four seasons.

Dendrochronology is the science of dating events in the environment in former periods by comparative study of growth rings in trees and aged wood. These māmane specimens are ready for study in Hart Lab, UH Hilo. Click photo to enlarge.

Until very recently, it was believed that trees native to and living in tropical climates did not produce rings or did not produce them at the same frequency or accuracy as others in non-tropical climates.

However, Uehana and Hart have discovered that some indigenous trees and nonnative trees surviving in Hawai‘i do in fact produce rings in areas of high elevation. According to Hart, the most surprising thing was finding annual rings in a tropical tree in Hawai‘i.

“We thought it was unusual but then found some nonnative trees planted by ranchers a long time ago, like cedar and different kinds of pine, lay annual rings here,” he explains. “They’ve taken that behavior from the continental United States and kept that annual growth behavior.”

The Hart Lab has dozens of core samples to date and evaluate—the research team’s goal is related to climate change but more specifically to prevention and preservation.

“One of our main goals as an ecology lab is to find out how to preserve species,” says Hart. “We are interested in finding out how long it takes to restore certain trees. This study gives us information on how fast they grow, how old they get, and how long it takes them to mature and be useful.”

They are using tree rings to obtain paleoclimatic data because in some areas of Hawai‘i there is only history as recent as the 1960s.

Uehana says, “In order to understand the way climate change will affect things in the future you need to look at things in the past.”

There is no good record of how climate has varied over time in the Pacific so taking the chronology further back to get a better understanding of how climate has been changing will be beneficial to predicting large scale environmental cycles.

Uehana uses the example of El Nino and La Nina.

“If you can more accurately predict how severe an El Nino or La Nina cycle will be then you can better prepare,” he says.

Hart also conducts bird research that uses algorithms to identify bird songs and sounds, which allows scientists and researchers to identify birds in a particular area by just sound alone. The preservation of the endemic palila (Loxioides bailleui) bird is one of the focuses of this research.

The māmane (Sophora chrysophylla), an endemic tree, provides food and habitat for the palila, hence the spawn of the tree ring research project.

“This tree ring study has farther reaching impacts beyond environmental, it is also ecological,” says Uehana. “This study can help us learn how to predict things in the future. If we know the next ten years will be drought years and we know that the optimum conditions for the māmane are just the opposite, then we can deduce that it will not only be a bad decade for the māmane but also a bad decade for the palila.”

The usefulness of prediction, Uehana says, is being able to take measures to counteract the bad cycles.

Hart says he loves working and mentoring students as well as watching them go on to be successful after they graduate and over time. He says true joy is seeing them become impactful on some level. The graduate students previously working on the tree ring project have their findings being published—Francisco has been published in the peer reviewed journal Tropical Ecology (“Annual rings in a native Hawaiian tree, Sophora chrysophylla, on Maunakea, Hawaiʻi“), while Ben has a study being published later this year.

Todd Belt

A political science professor at the University of Hawai‘i at Hilo has been awarded the prestigious John W. Kluge Fellowship in Digital Studies for 2017. The fellowship will put Prof. Todd Belt in residence at the Library of Congress in Washington, DC, from May to December of 2017.

The John W. Kluge Center at the Library of Congress awards the Kluge Fellowship in Digital Studies to researchers to examine the impact of the digital revolution on society, culture and international relations using the library’s collections and resources.

“My project evaluates how political humor in the context of presidential campaigns influences the information environment available to voters,” explains Belt. “I am particularly interested in what differences exist between information environments prior to and after the internet revolution, which gives the common citizen a greater hand, for better or worse in shaping what we learn about candidates and their policies.”

During the past few years, Belt has conducted research on internet communication and presidential campaigns, with a particular focus on the difference between citizen-generated content and commercially-generated content.

“The archives at the Library of Congress, particularly the National Digital Newspaper Program, gives me access to a vast database for analysis of the role of political humor in the information environment prior to the digital revolution,” says Belt. “These data will be combined for analysis with my ongoing collection of post-internet revolution digital media in order to inform my current book manuscript on political humor and presidential campaigns.”

Belt teaches courses at UH Hilo on “Congress and the Presidency” as well as “Politics, Media and Public Opinion” that relate directly to the area of research he’ll be conducting during his fellowship. He also teaches a “Methods of Research” course, which will further benefit from his hands-on research utilizing the cutting-edge archives of the Library of Congress.

Belt received his master of arts and doctor of philosophy in political science from the University of Southern California. He received the University of Hawai‘i Frances David Award for Excellence in Undergraduate Teaching in 2008.

Students are analyzing past and present cosmologies, discussing relationships between astrophysical and non-astrophysical perspectives, and placing them into historical, cultural, and personal context.

By Susan Enright.
This story is part of a series on new courses offered this semester.


Cathy Ishida

In a new course at the University of Hawai‘i at Hilo, students are studying and analyzing Maunakea as a contemporary place of contrasting world views. Cosmos and Culture (ASTR 381/394) delves into historical, intellectual, social, and cultural context of astronomical discovery from a multitude of perspectives including the exploration of both scientific and nonscientific cosmologies.

Students in the class are exploring the skills and knowledge astronomers need—in addition to astronomy—to engage constructively in conversations about the past, present, and future of Maunakea.

The course invites students to inquire deeply into the historical, intellectual, social, and cultural context of astronomy as a field of study, asking students to investigate topics such as cultural astronomy, the philosophy of science, the history of astronomy, Hawaiian studies, cultural studies and other fields.

“I hope stepping back and evaluating the big picture, whether it’s the cosmology of a particular culture, the scientific enterprise, or their own lives, will become a habit for students in this course,” says Catherine Ishida, who is teaching the class.

Ishida, who moved to Hilo in 2002 to work at Subaru Telescope, where she did research on interactions among galaxies and how they contribute to the evolution of galaxies over time, used her fluency in English, Japanese and astronomy to contribute to the observatory’s public information and outreach.

Ishida received her doctor of philosophy in astronomy from UH Mānoa in 2004. In 2007, she interrupted her work in astronomy to become an ordained minister in the Unitarian Universalist tradition, a multi-religious humanist faith.

Since returning to Hilo in 2011, she has been teaching at the UH Hilo Department of Physics and Astronomy and consulting with local congregations “teaching practical philosophy and impractical physics.”

“Just as people have looked at the same sky for ages and came up with different interpretations, the same facts can have different meanings for different people,” she explains. “Science majors in particular have few opportunities in their curriculum to examine how such differences affect the content and context of their field of study. I hope the course helps students better negotiate those differences in personal, professional and communal settings.”


Ishida says a key component of the new course is having students devise questions, invite conversation, and listen deeply to learn how astronomical and non-astronomical cosmologies inform people’s lives in Hawaiʻi today.

The course focuses on three areas: cultural astronomy, the scientific revolution, and cosmos and culture in contemporary Hawai‘i.

From the course description:

Introduction to Cultural Astronomy: After a basic review of fundamental skills necessary for successful cross cultural encounters, we’ll take a look at the variety of ways people have related to the sky through the naked eye prior to the wide dissemination of the Newtonian worldview.

The Scientific Revolution: Several developments began in the 15th century: global economic unification, technological and political dominance by Western Europeans, and a mechanistic worldview justified by the success of new ways of making truth claims. We’ll review basic concepts in the philosophy of science and apply them to close readings of the biographies of “iconic heroes of science.”

Cosmos and Culture in Contemporary Hawaiʻi: We’ll take a look at astrophysical cosmologies and non-astrophysical cosmologies that are alive in Hawaiʻi today by talking to people who live and promote them. Specific topics will include Hawaiian cosmology and star lore in the Hula traditions, Hawaiian wayfinding, developments in astrophysical research, and the institutions that sustain each of these.

Synthesis: We’ll apply what we learned throughout the semester to our own understanding of Maunakea as a contemporary locus for contrasting world views.

By the end of the course, Ishida says students will be able to describe a variety of past and present cosmologies, discuss relationships between astrophysical and non-astrophysical cosmologies, and place them into historical, cultural, and personal context. Students will also be able formulate a nuanced definition of science that reflects its complex realities.

“There are many issues that can be deeply personal, technical, and controversial in the local community,” she says. “The future of Maunakea is an obvious example, but there are other issues such as the future of agriculture and tourism. I hope that students will become skillful catalysts for meaningful conversation in the local community and beyond.”

The course gives students a unique perspective on microbial ecology and the health of the planet.

By Susan Enright.
This story is part of a series on new courses offered this semester.

A new course at the University of Hawai‘i at Hilo boosts students understanding of the diverse roles of microorganisms in both terrestrial and marine environments. Environmental Microbiology (CBES 698) focuses on microbial biodiversity, microbes in extreme environments, environmental applications using microorganisms, bioremediation, antibiotic resistance, and biogeochemical cycling.

Students are also learning about the mechanisms of microorganisms and how they interact with the environment in a diversity of ways.

“The course is beneficial to graduate students in the Tropical Conservation Biology and Environmental Science program in giving them a unique perspective on the microbial ecology of the diverse environments critical to supporting the health of the planet,” says Lisa Muehlstein, a UH Hilo lecturer in marine science who is teaching the class.

The course is the only microbiology oriented course in the graduate program. Although it is an elective, this course in combination with other graduate courses gives the students a holistic view of the environment.

“This perspective might otherwise be incomplete without the microbiology component,” explains Muehlstein.

Lisa Muehlstein

Muehlstein received her master of science in microbiology from Wright State University, Ohio, and her doctor of philosophy in botany from the University of Georgia.

Her initial research focused on seagrass disease and she spent time working in both temperate and tropical habitats with research projects. She moved on to conduct research on conservation issues in tropical seagrass habitats and spent many years working for the Virgin Islands National Park Service on a diversity of projects.

Since her move to Hawai‘i, Muehlstein is active in teaching at UH Hilo as a lecturer. Her course load has included the development of several new courses, including a successful online course, Current Issues in Marine Science, and lecture courses including Marine Microbial Ecology and the graduate course Environmental Microbiology.

The course provides an overview of the rapidly growing international fields of agritourism and food tourism.

By Susan Enright.
This story is part of a series on new courses offered this semester.

Brooke Hansen

A new course designed to help Hawai‘i move forward in local food production and tourism is being offered this semester at the University of Hawai‘i at Hilo. The course on Agricultural and Food Tourism is covering the momentum of foodie movements—locavore, Hawai‘i Regional Cuisine, farm-to-table, food festivals—to examine how they can support the flourishing tourist market.

Guiding the course are themes of sustainability, cultural respect and teaching people through the metaphors of “island as earth” and “we are all in one canoe.”

“The course is geared towards hearing from people who have already engaged with food and ag tourism and those who wish to,” says Kimberly “Brooke” Hansen, an adjunct faculty in anthropology who is teaching the course.

Guest speakers for the course include Audrey Wilson (acclaimed food writer), Tom Menezes (senior vice president of Hawaiian Crown), Pomai Weigert (Hawai‘i AgriTourism Association), Luisa Castro (master preserver and food safety expert), and Nancy Ginter-Miller (Produce to Product, Inc.).

“We tour local farms and foodie venues and explore multiple career paths from consulting and marketing to entrepreneurial opportunities in food and ag tourism,” explains Hansen.

The students in the course are an eclectic mix of traditional students exploring career options to non-traditional students who have experience farming crops such as avocados, mangoes and lychee.

The class also has Native Hawaiian students who want to embrace cultural tourism through food and heritage plants.

“Towards that end we will have a screening on March 6 of the acclaimed film Sons of Hālawa, about a family on Molokai who revitalized their relations with culture and land through a sustainable tourism enterprise,” says Hansen.

AG 194 Agricultural and Food Tourism

Course description:

The course provides an overview of the rapidly growing international fields of agritourism and food tourism from interdisciplinary academic approaches. With tourism as a major economic driver in many areas of the world, the exploration of markets for local and global tourism is paramount, especially those that intersect with popular food movements such as “farm to table,” “locavore,” “nose to tail,” street food tours, and locally HRC (Hawai‘i Regional Cuisine).

Sustainability, local culture and the promotion of self, society and planet are notable themes and marketing strategies. We will survey the global scope and local potential of these phenomena and examine trends, media influences, markets and marketing, logistics and regulations, value added product development, stakeholders, innovative partnerships and employment opportunities.

Specific areas covered include farm tours, food festivals, food trucks, farmers’ markets and agritourism associations.
