Managing outdoor water use while maintaining urban tree cover is a key challenge for water managers in arid climates. Urban trees generate flows of ecosystem services in arid areas, but also require significant amounts of irrigation. In this paper, a bioeconomic-health model of trees and water use is developed to investigate management of an urban forest canopy when irrigation is costly, water has economic value, and trees provide ecosystem services. The optimal tree irrigation decision is illustrated for Albuquerque, New Mexico, an arid Southwest US city. Using a range of monetary values for water, we find that the tree irrigation decision is sensitive to the value selected. Urban deforestation is optimal when the value of water is sufficiently high, or alternatively starts low, but grows to cross a specific threshold. If, however, the value of water is sufficiently low or if the value of tree cover rises over time, then deforestation is not optimal. The threshold value of water where the switch is made between zero and partial deforestation is well within previously identified ranges on actual water values. This model can be applied generally to study the tradeoffs between urban trees and water use in arid environments.

The natural range of longleaf pine ( Pinus palustris P. Mill.) and slash pine ( Pinus elliottii var. elliottii Engelm.) includes most of the southeastern US Coastal Plain, and there is now considerable interest in using these species for ecological forestry, restoration, and carbon sequestration. It is therefore surprising that little information is currently available concerning differences in their ecological water relations in natural stands. In this study, we compared water use, stomatal conductance at the crown scale (Gcrown), and whole-tree hydraulic conductance of mature pine trees growing in a naturally regenerated mixed stand on a flatwoods site in north-central Florida. We found remarkable similarities between longleaf and slash pine in stored water use, nocturnal transpiration, and whole-tree hydraulic conductance. Mean daily transpiration rate was higher for slash than for longleaf pine, averaging 39 and 26 L·tree–1, respectively. This difference was determined by variations in tree leaf area. Slash pine had 60% more leaf area per unit basal sapwood area than longleaf pine, but the larger plasticity of longleaf pine stomatal regulation partially compensated for leaf area differences: longleaf pine had higher Gcrown on days with high volumetric water content (θv) but this was reduced to similar or even lower values than for slash pine on days with low θv. There was no species difference in the sensitivity of Gcrown to increasing vapor pressure deficit.

Agriculture-to-urban water transfer is currently an important measure to meet the increasing water demand result from rapid industrialization and urbanization in China. Not only measuring benefits of agriculture-to-urban water transfer is critical to assess water transfer proposals, but also it can provide reliable basis for redistributing the benefits of agriculture-to-urban water transfer. This paper has developed a comprehensive framework in which Production Function Approach (PFA) is applied to quantify the value of water use in agricultural and industrial sectors, and Contingent Valuation Method (CVM) is employed to investigate the value of water use in municipal consumption and ecological environment. A case study from Zhuji in China verified the feasibility and validity of the method proposed in the paper. Results indicate that the Agriculture-to-urban water transfer increases the water value created by improving allocation efficiency of water use in different sectors. The benefits of agriculture-to-urban water transfer mainly origin from the fact that the economic value in industrial water-use are higher than which in the other sectors’ water-use. Meanwhile, the urban residents have a stronger desire to improve the water eco-environment which lead to higher water value in urban area.
