Climatic consequences of adopting drought tolerant vegetation over Los Angeles as a response to California drought utilized a regional climate model to analyze the impacts of drought-tolerant vegetation in Los Angeles. The results revealed that drought-tolerant vegetation contributed to a daytime warming of 1.9 degrees Celsius, largely due to decreases in irrigation, and a nighttime cooling of 3.2 degrees Celsius, due to differences in soil thermodynamics and heat exchange. The report concludes that the greater magnitude of the nighttime cooling could counterbalance the warming effects during the day.

Water Storage Investment Program Technical Reference details the methodology for quantifying the co-benefits or adverse impacts of water storage projects under California’s Water Storage Investment Program (WSIP). The report outlines methods for quantification of various co-benefits and adverse impacts, providing guidance on defining future site conditions, calculating physical changes, monetizing project benefits and costs, comparing benefits and costs, properly allocating costs to beneficiaries, determining cost-effectiveness and public-benefit ratio, and evaluating sources of uncertainty. Projects that quantify public benefits following these methodologies are eligible for California state bond funding to pay for the public benefits.

Life-cycle cost-benefit analysis of extensive vegetated roof systems assesses the benefits and costs of green roofs from a pilot study in Athens, Georgia, including private and social benefits. The public benefits identified were avoided best management practice costs, energy savings, and air quality, and the private benefits identified were stormwater utility fee credits, building energy savings, and air quality. The costs identified in the study included lifetime construction and maintenance. The study revealed that green roofs were 10-14% more expensive than conventional counterparts, and therefore, recommended that a broader range of positive social benefits be included in the analysis in order to outweigh the higher construction costs and encourage the construction of green roofs.

A framework for assessing urban greenery’s effects and valuing its ecosystem services identifies biophysical structure components of urban green space, the associated function, an indicator, effectivity factor, and ecosystem services associated. The framework compares the perceived value of the ecosystem service to other potential services (i.e., public transport, housing, or culture, compared to biodiversity, stormwater flood risk, and perceived well being). The article includes a case study in which the framework was applied to urban areas in Gothenburg, Sweden.
