Quantifying water processes within a forested catchment
By 2024, we will have identified and quantified the key above- and below-ground processes that govern water quantity and nutrient attenuation and transport within planted forested catchments. This new knowledge will provide the international scientific community with a fundamentally new understanding of the key processes governing planted-forest hydrology. The mechanistic processes will provide the key algorithms for our forest hydrology model to accurately simulate water quantity and nutrient attenuation in planted forests throughout New Zealand.
Spatially quantify forest water flux and storage at different scales with novel remote-sensing technology
By 2024, we will have developed a rapid, low cost, novel methodology to identify and quantify key hydrological processes spatially across a planted forest. This technology will enable:
- Accurate scaling of point measurements to the planted forest catchment scale;
- Accurate 3-dimensional modelling of key hydrological processes spatially across a forested catchment;
- Accurate modelling of water quantity and quality fluxes across multiple catchments and scales to the forest level.
These outputs will provide the key parameters and algorithms for the planted forest hydrology model to accurately calibrate and simulate water quantity and quality fluxes spatially in planted forests throughout New Zealand.
Develop and apply an assessment framework for the environmental, socioeconomic, and cultural impacts of planted forests on downstream water ecosystem services
By the end of 2024, we will have assessed the environmental, socioeconomic, and cultural impacts of upstream planted forests on downstream water ecosystem services. This will enable:
- Development of effective and efficient land-use regulations to promote positive impacts and mitigate negative impacts of planted forests on downstream water availability;
- Design of effective and efficient policy incentives (e.g., water compensation of planted forest owners using best forest practices) to promote the adoption of optimal-water-use forestry regimes.
Given the policy focus of this statement, our findings will be shared directly with key local stakeholders, policymakers, and relevant government agencies.
