Fired up about data mapping

Fire in Hawaii

Listen to Clay Trauernicht discuss his passion, and you’ll realize you haven’t been paying enough attention to wildfires in Hawai‘i. Fortunately, with the help of Tomoaki Miura’s GIS data-mapping project, he’s created a website and interactive map to help address this issue. Many may not realize wildland fires are a serious and growing problem in the Islands. But data compiled ... Read More »

Researchers find corn yields more sensitive to drought, climate change

Processing lab engineers better, safer food handling

ASoojin Jun and Kara Yamada

With Japanese visitors eager to buy Big Island Abalone products as omiyage, the Kona company turned to Associate Professor Soojin Jun. He had worked with NASA on flexible food packaging using retort pouches — vacuum-packed, steam-processed “canning” minus the heavy, landfill-clogging metal containers. It’s just one of the technologies Dr. Jun’s Food Processing Laboratory explores. Jun and master’s student Jin ... Read More »

Building biosensors to keep the food supply safe

Daniel Jenkins

Salmonella enterica accounts for nearly half the cases of food-borne illness worldwide. The bacterium causes hundreds of deaths and thousands of hospitalizations in the United States and racks up billions in medical costs and lost wages each year. Even agricultural producers who aren’t responsible for the outbreaks take an economic hit when fearful consumers stop buying their goods. That’s why ... Read More »

The Kamehameha butterfly is declining and needs the public’s help

The population of the Kamehameha butterfly—Hawai‘i’s state insect, which can be found nowhere else in the world—is on the decline, and University of Hawai‘i at Mānoa researchers are asking the public’s help to find out why. A team from UH Mānoa’s College of Tropical Agriculture and Human Resources (CTAHR) is launching the Pulelehua Project, which, with the public’s assistance, will ... Read More »

Predicting crop outcomes in a changing climate

Field of Corn

Environmental economics may sound like an oxymoron. Most people associate economics with business interests that are largely unconcerned with the environment. Some may feel that economics is the source of environmental problems. However, economics concerns more than business activity. At its core, economics studies how people allocate scarce resources, including environmental resources. The environment connects to economics in that people ... Read More »

[VIDEO] Plant breeder known for corn leaves lasting legacy

James Brewbaker at UH’s Waimānalo Research Station.

Corn developed over the last five decades by University of Hawaiʻi at Mānoa plant breeder James Brewbaker is feeding millions of people around the world. “Plant breeding is a wonderfully optimistic science because you do sometimes make these contributions,” said Brewbaker. Brewbaker was hired by UH’s College of Tropical Agriculture and Human Resources in 1961 and has spent much of ... Read More »

‘Super cool’ food storage options

Fruit with a thermometer

Dr. Soojin Jun of the University of Hawai‘i at Mānoa’s College of Tropical Agriculture and Human Resources (CTAHR) recently received a grant to study a high-tech new way to preserve food for storage and shipping.  Jun, an associate professor in CTAHR’s Department of Human Nutrition, Food and Animal Sciences (HNFAS), proposed a research project to address the loss of quality in ...
