2011 Annual Report

1a. Objectives (from AD-416)
1) Improve current decision making capabilities on HC&S land by building robust data on current practices (Temple, Parlier); 2) Create management plans to maximize yield and stability of feedstock production (Temple, Hilo); 3) Maximize bioenergy biomass stability and yield while minimizing environmental impacts at watershed scale (Temple, Parlier, Hilo); and 4) Improve water resource anagement and optimize biomass production for other production areas in the Hawaiian Islands and Pacific Basin (Temple, Hilo).

1b. Approach (from AD-416)
Objective 1:Develop spatial and temporal data sets form historic data for baseline analyses. Objective 2: Simulate current management impacts on feedstock yields and resource inputs. Objective 3: Demonstrate applicability of simulation approaches with validated present practices and explore watershed scale impacts of changes. Objective 4: Improve decision support for assessment of resource conditions, and utilize parallel computing and deep hydrology water balance.

3. Progress Report
This Reimbursable Agreement supports Objective 1 of the parent project. Biofuel is a renewable source of energy and there is a need to understand requirements of biofuel feedstock production on natural resources such as water and impact on the climate such as carbon dioxide (CO2). Progress has been made on the project includes recruitment of three postdoctoral researchers, a finalized plan for installing field instrument to measurement water vapor and CO2 fluxes, and initial data analyses of satellite imageries for describing crop growth conditions at near real time. This research will contribute to the development of a decision support system to determine water requirements and the feasibility of biofuel feedstock production and environmental sustainability on the Hawaiian Commericial and Sugar (HC&S) sugar cane lands in Maui, Hawaii and assessments of other potential biofuel feedstock sources across the Hawaiian Islands and other areas of the Pacific Basin. The project is monitored by the lead scientist through weekly conference calls with the project collaborators from HC&S, ARS Temple, and the University of Hawaii.
