    Insights

    Bank of America's Expansion in Paris

    Bank of America expanded operations in Paris in 2019 following the Brexit vote, aiming to serve its European clients seamlessly.

    Water Shortages in Arizona

    Arizona is facing water shortages due to a megadrought, with different perspectives on responsibility and concerns about future water access.

    Water Sources and Constraints in Arizona

    Central Arizona has large groundwater aquifers, but alternative sources of water are needed for certain areas. Reclaimed water and desalination are potential options.

    Regulations and Challenges in Managing Water Resources

    Groundwater pumping restraints and increased demands from cities and industries have created constraints on groundwater in Arizona. The Colorado River system is also experiencing diminished flows.

    Water Pricing and Economic Implications

    The cost difference between developer and farmer water rates is due to renewable water supplies and infrastructure development. Agriculture in the desert Southwest is water-intensive.

    Challenges and Opportunities for Arizona's Water Management

    Industrial uses of water, such as semiconductor production, contribute to the demand mix. Proper management can ensure that water constraints do not hinder economic growth.

    Arizona's Ability to Handle Water Scarcity

    Arizona's extreme heat and dryness make it well-suited to handle climate change. Desalination is a potential solution, but decisions about water rights and political viability pose challenges.

    Bank of America's Expansion in Paris

    00:00 - 07:44

    • Bank of America expanded operations in Paris in 2019 following the Brexit vote.
    • The bank aimed to be a one-stop shop for its European clients and bring the full spectrum of its services to Paris.

    Water Shortages in Arizona

    07:17 - 16:23

    • Arizona is facing water shortages due to a megadrought that has been ongoing for 25 years.
    • Different perspectives exist on who is responsible for the water scarcity.
    • The governor of Arizona announced constraints on new development around Phoenix to address water scarcity.
    • Developers blame farmers for using 80% of the water in the desert, while farmers argue that there wasn't a problem until decisions about water usage were made by others.
    • There is concern about water availability for industries like semiconductor manufacturing.
    • The big question is who will lose access to water in the future and how decisions about prioritization will be made.
    • Arizona has progressive groundwater management laws that tie water availability to growth.
    • Developers must demonstrate 100 years of available water before subdividing land for development.
    • All groundwater in the Phoenix metropolitan area is allocated for use over the next 100 years.
    • New growth must occur where there is already an assured water supply or rely on sources other than groundwater.
    • The announcement by the governor aims to protect existing claims on groundwater and limit growth on this resource outside designated areas with assured supply.
    • The exact amount of available water in Arizona depends on different sources, including groundwater.

    Water Sources and Constraints in Arizona

    16:01 - 24:09

    • Central Arizona has large and productive groundwater aquifers, but it is fossil groundwater that is not annually renewed.
    • Phoenix benefits from three main rivers and imported Colorado River water as significant sources of surface water.
    • To build or grow in certain areas, entities need to find alternative sources of water other than groundwater.
    • Developers can purchase higher priority water rights from farmers or lease water from Indian tribes.
    • Groundwater basins outside the Phoenix Metropolitan area can be pumped and transported to meet the demand.
    • Reclaimed water and desalinated ocean water are also potential sources of water.
    • Water constraints are caused by farming, urban development, and population growth.
    • Farming in the desert southwest requires a lot of water and continues to draw from the aquifer perpetually.
    • Cities have grown in population since World War II and rely on the aquifer for potable water needs.

    Regulations and Challenges in Managing Water Resources

    23:43 - 32:13

    • Groundwater pumping restraints under the 1980 Grand Water Management Act have created constraints on groundwater in Arizona.
    • Cities, industries, and population growth have increased demands on the aquifer for potable water needs.
    • The state has intentionally regulated to protect and guard groundwater resources for the future.
    • Surface water in Phoenix is managed by the salt river project and is relatively resilient and sustainable in the face of climate change.
    • Arizona's hot and dry climate makes it less susceptible to significant impacts on surface water flows compared to other regions.
    • The conversion from agriculture to urban use in Phoenix has resulted in natural water savings built into the system.
    • The Colorado River system is overallocated and experiencing diminished flows due to drought and climate change.
    • The Bureau of Reclamation has called for significant reductions in water consumption to stabilize the Colorado River system.
    • Farmers have a perpetual right to pump groundwater under the grandfather clause, but they don't pay much for it compared to cities or private water companies.
    • Developers are required to invest in renewable surface water supplies instead of relying on fossil groundwater.

    Water Pricing and Economic Implications

    31:43 - 39:52

    • The cost difference between what a developer pays for water versus what a farmer pays for water is due to the acquisition of renewable water supplies and the need to develop infrastructure.
    • On the Colorado River, farmers and Indian communities have the highest priority water rates based on first-in-time first-in-right.
    • Water constraints cannot be solved solely with better water management and newer information; reinvestment in aging infrastructure will help but not be the answer.
    • Investing in pipelines is important for water quality and resiliency, but unlikely to be deployed at scale.
    • Arizona's desert conditions make it a great place to grow food, but agriculture in the desert Southwest is very water intensive.
    • Growing vegetables in the winter is complex due to logistics, refrigeration, labor supply, and quality control.

    Challenges and Opportunities for Arizona's Water Management

    39:25 - 47:37

    • The agriculture in western Arizona is highly complex and industrial, not cute family farms.
    • Farmers with higher priority water rights will face increasing pressure to sell as the Colorado River diminishes.
    • Arizona could potentially impose a tax on the consumption of water to price it differently, but it may not be politically viable.
    • Industrial uses of water, such as semiconductor production, are also water-intensive and contribute to the demand mix.
    • The desert Southwest is attractive for high-tech industries due to its stable climate, but this adds to the water demands.
    • Water constraints do not necessarily have to act as a constraint on economic growth if managed properly.

    Arizona's Ability to Handle Water Scarcity

    47:12 - 50:55

    • Arizona's extreme heat and dryness make it well-suited to handle climate change.
    • Desert cities have always existed and humans have always lived in deserts.
    • Desalination of water is a potential solution for the future, but currently too expensive to be deployed at scale.
    • Decisions about water rights are mostly already made in the West, with exceptions for Native American tribes.
    • The conflict between what is economically less expensive and politically more difficult will be interesting to watch.
