Agricultural Resource Management

The Agricultural Resource Management Division administers the development and management of key agricultural resources.

Land and water are two ingredients essential to sustaining agricultural operations. In recognition of Hawaii’s limited land and water resources, the State Department of Agriculture is charged with preserving these important resources to ensure the viability of Hawaii’s diversified agricultural industry.

Through its Agricultural Resource Management Division, the department operates the State’s Agricultural Park Program. The major objective of this program is to assist people who are interested in leasing land for farming ventures by providing irrigation water, reasonably priced farmland with infrastructure and facilities to encourage competition within the industry.

The program is composed of three separate sub-programs:

The State of Hawaii, Department of Agriculture (HDOA) has completed a Master Plan, Feasibility Analysis, and Conceptual Design for a Scalable and Replicable Livestock Harvesting Facility.  The effort was completed with the coordination, support, and guidance of the Hawaii Cattlemen’s Council, Inc. (HCC).  The goal of the project was to create a facility model that serves the sustainability needs of Hawaii’s livestock industry and discusses the socio-economic and environmental factors of such a facility.

This project could not been completed without the expertise and valuable input from industry experts, stakeholders, and the HCC. The HDOA is grateful for their time and cooperation.

The final master plan and feasibility analysis, and the conceptual plans (60 % design drawings) can be found at the links below:


Agricultural Water Use and Development Plan Update

An update to the Agricultural Water Use and Development Plan (AWUDP 2019 Update) is available online!

This update was developed by the Department of Agriculture in accordance with Hawaii Revised Statutes 174C-31(e).  This plan provides an update to the original AWUDP published in 2003 and revised in 2004.  Both the 2004 AWUDP, and the newly completed AWUDP 2019 Update, work together as a living document that will continue to be revised and updated in years to come.

The AWUDP 2019 Update is a tool that may be used by irrigation system managers, farmers, ranchers, planners, and others who rely on agricultural water to support diversified agriculture.  Some highlights of the AWUDP 2019 Update include:

  • Inventory of irrigation systems that were not covered in the 2004 AWUDP
  • Update of irrigation systems that were covered in the 2004 AWUDP
  • Update of the agriculture planning water demand rate and water demand forecasts
  • Short- and long-term plan to manage irrigation systems in the state

Farmers are often interested in the Agricultural Water Demand Planning Rates. In this AWUDP Update, this value is revisited through extensive data gathering and research, including additional farm surveys and historical data.  This AWUDP Update determined that multiple water demand planning rates are necessary to represent different conditions and crop types. These rates are summarized below.

  • 3,900 gpd/acre for diversified agriculture for usable acreage that is 50% planted (e.g. leafy vegetables and truck crops)
  • 7,800 gpd/acre for diversified agriculture for usable acreage that is 100% lands planted (e.g., nursery, feed, and forage crops)
  • 8,100 gpd/acre for diversified agriculture, for usable acreage that is 50% planted, under drought conditions or in dry areas.
  • 16,200 gpd/acre for diversified agriculture, for usable acreage that is 100% planted, under drought conditions or in dry areas.
  • 8,000 gpd/acre for irrigated pastures (usable acreage that is 100% planted)

Please note that these water demand rates are for statewide planning purposes for agricultural water demand.  If a specific site is being studied, a site-specific water demand analysis should be completed.

This 2019 AWUDP Update could not have been completed without the support and cooperation of the farmers, ranchers, and irrigation system owners/operators that took the time to talk with us about agriculture.  The document contains input from over a hundred different farmers across the state, and we are greatly appreciative for their input and knowledge.  The 2019 AWUDP Update would not be the same without them!

  • East Maui Water Systems Improvement Project
    In 2018, the Hawaiʻi State Legislature appropriated funding for capital improvement project (CIP) funding for plans, design, and construction for irrigation and water delivery systems in East Maui to support agricultural purposes.  The legislative intent was to primarily support the small farmers in East Maui in furtherance of the State’s goals of food security and self-sufficiency.In May 2019, the Hawaiʻi Department of Agriculture and its Project Team introduced the East Maui Water Systems Improvement Project (Project) to the community, and specifically the East Maui community.  Phase 1 of the Project entailed the Project Team meeting with key stakeholders to gather relevant input to identify and assess potential projects for HDOA’s consideration.  During this phase, we also conducted site visits of potential projects and held two public meetings to update the community and gather additional input.Based upon the community engagement, the Project Team conducted site assessments for the potential projects, taking into consideration the feasibility of completing each proposed project based upon a matrix of key factors.  The Project Team prepared a prioritization matrix to assist HDOA in determining which proposed projects should proceed to the design phase.  We are currently in the design and regulatory process phase to ensure timely use of the CIP funds.This process is detailed in the East Maui Water Systems Improvement, Proposed Project Summary Report dated December 16, 2019: you have any questions, please contact Janice Fujimoto with HDOA at 808-973-9473 or via email at [email protected]. or Dawn Chang with Kuiwalu at [email protected].
