Busy Week: Speaking, Sponsoring & Aerial Photography

Richard Ha writes:

It’s been a busy week.

It started out with my being part of a panel discussion for the Ulumau IX class.

This was the 9th class of the Hawaiʻi Island Leadership Series called Ulumau, which was founded by Mark McGuffie in 2003. It has its roots firmly planted in the core values of Hawaiian Values, Community and Servant Leadership.

Unlike a traditional “leadership” class, where attendees are usually taught how to “manage” people, Ulumau expands the ranks of community leadership by providing a broad range of leaders (both existing and emerging) who have the knowledge and incentive to confront the needs of our specific community.

There were five of us on the panel. Jeff Melrose gave an overview of agriculture and what different types of farming are happening where on the Big Island. Everyone should see his presentation, which gives the context in which agriculture exists on the Big Island.

Nancy Redfeather talked about the school garden network and the many other outreach events she is involved in. She touches a large group of people. Other speakers were Elizabeth Cole, deputy director of the Kohala Center, and Amanda Rieux, who leads the culinary garden, the Mala‘ai Garden, at Waimea Middle School.

I talked about agriculture and energy, and how they are inextricably tied together. I also explained about how food security involves farmers farming, and that if the farmer makes money the farmer will farm.

I am helping to sponsor students in the Sustainable Hawaii Youth Leadership Initiative (SHYLI). This group’s mission is “to inspire young people to envision, plan and create a more sustainable future for their lives and their island.”

The students I’m sponsoring are Sherry Anne Pancho and KaMele E. Sanchez, who were both Big Island delegates to the Stone Soup Leadership Institute's 9th Annual Youth Leadership Summit for Sustainable Development conference on Martha’s Vineyard this summer. They came by the farm a few days ago to give a presentation of their project on hydroponic food production.

This is something I can help with, and I will track and write about their progress. I am very interested in supporting our next generation leaders as they work on ways to continue and improve our food security through changing and difficult times.

A crew from the University of Hawai‘i at Hilo came by the farm to test an unmanned aerial vehicle. “Flight Control” was in the back of the pickup, where the screen was, so we could see what the camera was viewing.

Banana Survey 4

They set up a GPS coordinate, and the little six-bladed chopper flew the route as directed by the program. It was set up to fly parallel, overlapping camera runs until our whole banana field was filmed. Then they will make the recording into one large map.

Besides doing a photographic imaging, they ran a light spectrum recording. The value of seeing our banana plants from the air in different light spectrums is that we will be able to see where plants are stressed and take corrective action. The possibilities are immense. This is so interesting to me.

All three of these things that happened this week had to do with the future. I’m not only thinking of our farm and profit from day-to-day; it’s much bigger than all that. It’s the future – of Big Island farming, of our people, of our island.

Sometimes looking forward is actually about looking to and learning about how we used to do things, and I will continue to write posts about what I’m doing in those areas. And sometimes, it’s looking at new technologies and ways. Always it’s about talking with the young people coming up, so we can share what we know and discuss some of the challenges they are going to be facing.

Conversations With My Mom

I took Mom to Hamakua Springs to get a few tilapia for her dinner.

While we were there, we looked at some of the things we have going on.

One thing that strikes me is how much water we have running through our 600-acre farm. We must maximize its usage.

Reservoir

Water Supply will build a new reservoir adjacent to this one and bring electricity right through the farm to the new well, which is right behind this reservoir

I really want to raise tilapia when the price of oil goes so high that bringing it in from Asia is prohibitive.

Tilapia for mom

Tilapia for Mom. These are the small ones, to fry crispy.

And, while doing that, we want to demonstrate how Hawaiians were self-sufficient in ancient days.

Then while we are at it, we want to reforest the streams with ‘ohi‘a, koa, bamboo, kukui, hapu‘u, etc.

  1. Also, how about aquaponics with tilapia and taro?
  2. How about a certified kitchen to make lomi salmon, poi and other things where we and other farmers can add value?
  3. What about classes for at-risk students?
  4. Maybe a permanent imu.
  5. Events set around food?
  6. How about showing how food was produced then and now – ancient and modern?

Mom and I always have these kinds of conversations. I like it.

Kahua Ahupua‘a

The last few days, I’ve been focusing on Kahua Ahupua‘a. Of the three ahupua‘a that comprise Hamakua Springs Country Farms, I find this one the most interesting.

Within 600 feet there are two streams: Makea on the north boundary, and Ali‘a on the south. Between the streams is a ridgeline, maybe 75 to 100 feet from stream level, and running on the ridgeline from mauka to makai is a cane haul road.

It has a clear view of both Mauna Kea and the ocean, as well as of the greenhouses in the valley facing north, toward Honoka’a, and the banana fields facing south, toward Hilo. June and I plan to eventually build a house there. We just submitted a plan to the County in order to subdivide.

Yesterday I spent several hours on the bulldozer, reopening old roads and clearing access to the streams. Today I spent time knocking down many, many 20-foot albizia trees, and making sure the roots were completely pulled out of the ground. There’s one giant albizia tree that is even larger than the ones in this picture. The base is at least 10 feet around and the tree is easily 100 feet tall with many giant side branches. That’s where the seeds for the others are coming from.

I wonder how I’ll get rid of it. Cutting it down is just unimaginable. Here is how they cut a tree down at Lyons Arboretum.

Here is an easier way, with a drill and injecting.

The whole time on the bulldozer, I was thinking about how I can situate some hydroponic hoop houses that would allow us to capture fertilizer runoff, grow algae and raise tilapia. I would get the water further upstream, at a higher elevation, and then run it to the hydroponic hoop houses and use the excess fertilizer to grow algae and then, further downstream, send it to the tilapia. Gravity and free water are our friends.

I am going to grow algae for fuel. Not for cars, but to grow tilapia. Food fuel. The hydroelectric project is close by.

I’m also thinking of making a place to just sit and listen to the stream. I wonder where I can get hapu‘u? Where would kukui nut trees go? Lauhala? Ulu? Hmmm.

This is going to be a big, long project. I’ll write about it as I go along.
