My recent research, centered around prediction of the water balance, i.e., what fraction of precipitation goes to plants and what to run-off, as a function of climatic variables (solar irradiance and precipitation), just appeared in GSA Today. https://doi.org/10.1130/GSATG471GW.1 as well as in our AGU/Wiley book. Solution of this problem is the central goal of NSF's Hydrologic Sciences program as well as a defining focus of NSF Ecology and the Food Energy Water Nexus. The solution grew out of our soils research into water flow, solute transport, chemical weathering, soil formation, and vegetation growth. See our new book (Hydrogeology, Chemical Weathering and Soil Formation) https://www.barnesandnoble.com/w/hydrogeology-chemical-weathering-and-soil-formation-allen-hunt/1137022160 and its description in Eos (Transactions of the American Geophysical Union) https://eos.org/editors-vox/exploring-the-engine-and-drivers-of-soil-formation This book, an international collaboration, became an AGU "Best Seller."

See Eos (Transactions of American Geophysical Union) Editor's Vox https://eos.org/editors-vox/the-spaces-in-between for discussion of our 2017 Reviews of Geophysics article, including its possible implications for the cause of the great Permian Extinction (severest of all geologic extinctions).
Determined the temporal and spatial scaling of variables important to agriculture, soil sciences, and ecology: 1) Infiltration, evapotranspiration, run-off, vegetation growth and productivity, as well as chemical weathering and soil formation. Used a simple optimization of NPP with respect to the water fluxes, evapotranspiration and run-off, to find the relative magnitudes of these principal components of the whater balance (partitioning of water at the terrestrial Earth's surface. Applications of great importance to carbon and water cycling. Apply the research regarding the dependence of vegetation growth rates on transpiration to the prediction of the local variability of intraspecific tree heights due to soil type, microclimate, hillslope curvature, and slope aspect (Ecological Modelling). Apply the predictions regarding soil depth as a function of time to the assessment of slope stability against landsliding (Geochemistry, Geophysics, Geosystems).
Predict the water balance, i.e., how water is partitioned at the terrestrial Earth's surface.
In a new discussion article in the international AGU/EGU journal Nonlinear Processes in Geophysics, we show that the same predictive relationship for plant growth, which gives verifiable root system extent for times up to 100,000 years, works also for river drainage organization out to time scales of 100,000,000 years. One parameter must be changed: for plants the relevant flow rate is the water flow in the unsaturated zone, but for rivers, it is the groundwater flow rate in the saturated zone. This completes our description of the dimensions of the critical zone, between the bedrock and the treetops, in that we can predict its depth and horizontal extent on the time scale since the break-up of Pangaea.
Use past results on soil formation as a function of water infiltration and on predicting infiltration from optimization of net primary productivity to develop fully predictive steady-state model of land surface vegetation and soil development in terms of climatic variables.
Use the above results to predict effects of climate change (disruption to steady-state conditions) on water resources and food production.
Use the resuts on root growth patterns to predict characteristics of invasive species.
