Research Project: Resource Assessment Framework for Dependable Feedstock Supply to Produce Advanced Biofuels in Hawaii

Location: Grassland, Soil and Water Research Laboratory

Project Number: 3098-13610-007-11
Project Type: Specific Cooperative Agreement

Start Date: Apr 15, 2011
End Date: Sep 30, 2015

Objective:
1) Improve current decision making capabilities on Hawaii Commercial and Sugarcane (HC&S) land by building robust data on current practices; 2) Create management plans to maximize yield and stability of feedstock production; 3) Maximize bioenergy biomass stability and yield while minimizing environmental impacts at watershed scale; and 4) Improve water resource management and optimize biomass production for other production areas in the Hawaiian Islands and Pacific Basin.

Approach:
Collect and synthesize available topography, soils, climate and historical management data. Improve ALMANAC Soil Carbon modeling abilities with historical and contemporary. Initial ALMANAC runs with historical data (plant growth parameters, soils, precipitation, etc.) on three individual fields under current management. ALMANAC runs with current sugarcane as compared to other potential biomass crops on 3 individual fields. ALMANAC simulation changing agronomic management to achieve maximum yields on 3 individual fields. Install or identify fields/plots of sugarcane and other biofuel crops in Hawaii. Measure plant physiological and soil parameters over time, under changing climatic conditions. With improved model, simulate alternative agronomic management of additional fields, including changing feedstocks, and nutrient and water management. Conduct a biomass production assessment for potential agricultural production areas of the islands using ALMANAC. Develop and analyze Island-wide scenarios, as defined by local stakeholders, related to the impact of bioenergy feedstock development on annual production risk, water resources, potential carbon sequestration, and displacement of other agricultural and natural systems. Explore applicability of the models on other islands and countries in the Pacific Basin.
