Repurposing Vacant Properties as Green Infrastructure-Unger, 2012

Embed Size (px)

DESCRIPTION

Thousands of acres of Great Lakes urban vacant properties can be turned from liabilities to assets as green infrastructure. We are working with water infrastructure agencies, land banks, non-governmental organizations working in urban neighborhoods, and analyzing the potential for green infrastructure to include social equity, economic growth, and ecosystem services.

Remediating Water & Vacant Lands Issues With Ecosystem Services- Gained substantial attention with publication of

Costanza et al.’s 1997 Nature paper which valued the world’s ecosystem services at $16-54 trillion or 88-300% of global GDP at the time.

- “These “ecosystem services”—the storage of carbon in trees, the pollination of crops by insects—are often closely tied to the economic fortunes of the poorest in the developing world.” The Economist “The Road to Rio” 11/17/11

- “To protect its watershed, New York pays farmers in the Catskills not to develop their land.” The Economist “The world’s lungs” 9/23/10

- “The city plans to spend $660 million to preserve that watershed in good health; the alternative, a water treatment plant, would have cost $4 billion to build.” The New York Times “How Much Is Nature Worth? For You, $33 Trillion” 5/20/97

- The USDA’s Conservation Reserve Program (CRP) “Benefits”: “protects millions of acres of…topsoil from erosion and is designed to safeguard the Nation's natural resources…reducing water runoff and sedimentation…protects groundwater and helps improve the condition of lakes, rivers, ponds, and streams. Acreage…planted to resource-conserving vegetative covers, making the program a major contributor to increased wildlife populations in many parts of the country.” (CRP: Status and Current Issues, CRS Report for Congress, 9/15/2010)

- 31.3 million acres as of July 2010 (↓10.9%) at $53-129 per acre

- Already a prime example of ecosystem service efficacy and supply-side acceptance

- ''Nature's Services; Societal Dependence on Natural Ecosystems” by Gretchen C. Daily

Remediating Water & Vacant Land Issues With Ecosystem Services- Collective property regimes (Acheson 1988, Cole 2002):

- England’s open-field system- Andean Mountain common-field agricultural tradition- Japanese Iriachi common lands- Maine’s “harbor gangs”- Great Lakes Basin’s Vacant Lands?????

- Flood control, soil formation, pollination, food and timber production, provision of the raw material for new medicines, recreational opportunities and the maintenance of a favorable climate are among them.

Municipal Concerns

How to maintain economic viability of shrinking cities?

• Continuous economic growth may not be realistic assumption“…advance the steady state economy, with stabilized population and consumption…Continuous economic growth on a finite planet is wishful thinking…limits to growth…[including] physical and ecological principles…a way to achieve sustainability and equity in an increasingly constrained world…work[ing] closely with economists and scientists…” — Center for the Advancement of the Steady State Economy (CASSE)

• Embrace shrinkage?“It’s reality. We’re simply recognizing and accepting the reality of what’s happened to this city over the past several years…We haven’t gone in and aggressively shut down streets, but, over time, that’s part of the plan.”— Jay Williams, Youngstown, OH

“Decline in Flint is like gravity, a fact of life. We need to control it instead of letting it control us. A lot of people remember the past, when we were a successful city that others looked to as a model, and they hope. But you can’t base government policy on hope. We have to do something drastic.”— Dan Kildee, Flint, MI

Municipal Concerns

How to maintain economic viability of shrinking cities?

• Minimize social disruption and protect property values

• Enhance vacant land fiscal condition—maximize revenues or minimize costs

• Protect and restore natural resources

Background• Revitalization efforts in Great Lakes cities

• local• small-scale• variable

• Large-scale, regional revitalization: Does it make sense? • triple bottom line: social, environmental, economic• needs research to justify investment

Headline Vs. Real Spread Growing Wider• “Distinctions must be kept in mind between quantity and quality of growth, between costs and returns, and between the short and long run. Goals for more growth should specify more growth of what and for what.” — Simon Kuznets, New Republic, 1962

• Expropriating distant “elsewheres”

• Municipal compost to replenish/remediate vacant lands would generate $24.23 million in revenue, 7,352 jobs, $182-311 and $4.37-7.45 million in wages and taxes, and would offset 6.65 MT CO2 or 31% of N Ohio’s urban per capita emissions

• N Ohio’s urban trees provide $3.6-22.4 million in pollutant remediation

• Agroforestry (aka, carbon farming)

• Strategies:

• intercropping, black walnut, silvopastoral, windbreaks, biofuels (Current urban tree estimate NTFB $199 million or $202 per capita annually)

• R&D:

• biological processes, erosion control, wildlife, vacant lands, specialty products, fine hardwoods, waste application, biomass and pulp

•Versus conventional farming:

• Increase (+) = 702 tons harvest, 687 tons N Inputs, 21,599 labor hours, $809,955 Net Revenue

• Decrease (-) = 4,759,236 kW of non-solar NRG inputs, 107 tons fertilizer, 48 tons N losses, 19,047 tons soil loss

• Agroforestry (aka, carbon farming)

• Benefits:• Reduce wind/H2O erosion• Reduce N2 fixation (offset tremendous urban N2O

emissions)• Reduce leaf decay• Increase yields due to reduced winds, cooler

temps, and less evapotranspiration• Energy savings of 15-30%• Bee/butterfly habitat ($75-188 million demand

value/$107 million supply value; $6.23 million in fruit & grain value; 16-40 plant species; 1.35-3.37 bird species)

• Shade for livestock• Absorb greenhouse gases¶

• Uneven or Even-Aged Forestry

• Uneven:

• More Continuous supply of NTFB and TFB revenue (High Value Crops), precipitation infiltration, Heat Island alleviation, carbon/nitrogen (NO3- & NH4+)/phosphorus (PO4

2-) sequestration → Reaches asymptote w/in 50 years

• Even-Aged:

• More Discrete supply of NTFB and TFB revenue (Low Value Crops), precipitation infiltration, Heat Island alleviation, carbon/nitrogen (NO3- & NH4+)/phosphorus (PO4

OverviewHow this group can be involved:• Feedback, Participation, Economic

Equivalents or Proxies on Vacant Land

Examples:• Great Lakes Ag/Resource Econ Assoc

(GLAREA) Land Use Policy Workshop

Four fundamental questions:• Appropriate role of Social Science in land

conservation and development policy?• Why, where, when does land conversion occur?• What are land conversion & conservation

implications for property values/taxes, and vice versa?

• What are practical relationships among urban amenities, character, and policies designed to protect, create, or transform them?

Page 23: Repurposing Vacant Properties as Green Infrastructure-Unger, 2012

Triple-Bottom Line Approach

• Social, economic, environmental concerns• Institutional, short- Vs. long-term, health, etc.

Cleveland Federal Reserve Inaugural Community Survey Top 3 Issues¶:

• Availability of Local Employment Opportunities, Vacant Properties, Budgetary Cuts and Financing Issues at the State Level

• “Federal budget cuts will cripple our operations.”• “No jobs, no income, no credit, no housing.”• “There is no apparent job growth to replace the elimination

of public-sector and service-sector jobs lost because of budget shortfalls”

• “New business and jobs must be at the top of every list. Suitable business development for small and rural communities is critical for this region, and appropriate tactics must be employed to address this issue. Entrepreneurship, rural business development (including farming), small-scale manufacturing, alternative energy, traditional energy, tourism, food, and technology-based businesses must be developed from within to stabilize and grow these communities.”

¶ Others included home foreclosures, quality K-12 education, small business loans,federal and local budgetary cuts, affordable housing, credit scores
