    1. 1. London Community Resource Centre Best Practices for Community Gardens Presented by: Cirrus Consulting Group Jeremiah Brenner, Martha Fallis, Dane Labonte, Josh Wise I.D.E.A.S Conference Friday April 16, 2010
    2. 2. • LCRC is a volunteer-driven, non-profit, charitable organization • The London Community Resource Centre (LCRC) has been an integral part of the City of London for more than 30 years • LCRC actively addresses the issue of food security that affects a broad scope of residents in the city • At present there are 22 community gardens across the City of London managed by the LCRC What is a community garden? A shared piece of land where people rent garden plots, grow vegetables, fruits and herbs of their choice LONDON COMMUNITY RESOURCE CENTRE (LCRC)
    3. 3. Economic Social Environment Examine the environmental sustainability of the 22 LCRC community garden sites scattered throughout the City of London Focusing on 3 Aspects: •Maintenance Best Practice •Watering Supply Issues •Environmental Audit Framework PROJECT SCOPE Sustainability

    11. 11. BEST PRACTICES GUIDE Considerations • Transparent way to determine Best-Practices • Method which allows us to give relative weights to different criteria (depending on impact level) Our process • Defined the Methods for each consideration • Defined the Environmental Criteria • Employed Multi Criteria Evaluation to determine most environmentally friendly Method
    12. 12. • No-Till with Mulch Cover • No-Till with Cover Crops • Shallow Till with Hand tools • Deep (er) till with roto-tiller • Deep (er) till with harrow tiller DEFINING TILLING METHODS
    13. 13. • Disruption of Soil Horizons (on-site impact) • Erosion Effects (on-site impact) • Disruption of Organisms (on- site impact) • Effects of Soil Moisture (on- site impact) • Effects to Nutrients (on-site impact) • Fossil Fuel Use (external impact) • Seedbed Prep (on-site impact) TILLING ENVIRONMENTAL CRITERIA
    14. 14. Compares the various Environmental Criteria based on level of importance • Incorporated a Weighted Linear Combination • Creates Scores for each Criteria Determines the level of impact for each Method (positive or negative) Final Score = (Environmental Criteria Score) * (Method’s level of impact) MULTI-CRITERIA EVALUATION
    15. 15. Environmental Criteria No-Till (Mulch and Cover Crops) Shallow Till (Hand Tools) Soil Horizons Erosion Effects Organisms Soil Moisture Nutrients Fossil Fuel Use Seedbed Prep BEST TILLING PRACTICES
    16. 16. • Primary Recommendation: • Implement No-Till Gardening through mulch or cover crops • Secondary Recommendation: • Implement Shallow-till Gardening through hand-tool use • Secondary Recommendation (B): • Ensure proper timing with roto-tiller and inspect soil quality bi-annually TILLING RECOMMENDATIONS
    17. 17. • Conventional • Conventional Organic • Cover Crops • Mulch • Homemade Compost FERTILIZER METHODS
    18. 18. • Nutrient Release (on-site impact) • Potential for ‘Plant Burning’ (on-site impact) • Energy to produce (external impact) • Local availability/ collection methods (external impact) • Soil moisture effects (on-site impact) • Possibility for runoff (external impact) FERTILIZER ENVIRONMENTAL CRITERIA
    19. 19. Environmental Criteria Compost Mulch Cover Crops Nutrient Release Plant Burning Energy Availability Soil Moisture Runoff Nutrient Release BEST FERTILIZER PRACTICES
    20. 20. Primary Recommendation • Promote the use of home- made compost Secondary Recommendation • Increase education for responsible fertilizer usage FERTILIZER RECOMMENDATION
    21. 21. IRRIGATION METHODS Hand watering Furrow irrigation Sprinkler irrigation Drip irrigation Microsprinkler irrigation Clay pot irrigation
    22. 22. IRRIGATION ENVIRONMENTAL CRITERIA • Root Zone • Evaporation • Transpiration • Deep Percolation • Runoff • Drift Maximize Efficient Water Application Minimize Water Loss
    23. 23. Drip Irrigation • Best water efficiency • Can be designed with gravity fed system Challenges • Maintenance complexity • Cost • Vandalism Clay Pot Irrigation • High water efficiency • Historic interest • Hands on watering Challenges • Cost • Lack of literature • Tilling IRRIGATION METHODS RECOMMENDATIONS
    24. 24. IMPROVING HAND WATERING Proper Technique •Runoff •Evaporation •Deep Percolation •Drift Scheduling •Evaporation •Deep Percolation Mulching •Evaporation •Runoff Furrows •Runoff • Dominant form of irrigation • Potentially high water loss • Cheap equipment • Social benefits • Highly controllable
    25. 25. WATER SUPPLY Sources •Onsite Taps •Water Tanks •Rain Barrels •Wells Considerations •Ability to meet water needs •Cost •Maintenance hours •Environmental Impacts
    26. 26. WATER SUPPLY RECOMMENDATIONS Onsite Taps •Best solution for water supply needs •Future Planning Challenges •High capital cost •Reduces water conservation incentives Well •Good for meeting water supply Needs Challenges •High capital cost •Reduces water conservation incentive •Source water protection concerns
    27. 27. WATER SUPPLY Rain Barrels •Improve LCRC environmental performance •Low capital cost •Connect gardeners with conservation Challenges •Need additional filling •No collection area at some sites Water Tanks •Helps meet current needs •Low capital cost Challenges •No water catchment •Needs additional filling Recommendations •Improve harvesting •Create communication links •Education about importance of water conservation
    28. 28. Environmental Audits • A management tool: – An evaluation of the performance of the organization – Designed to protect the environment – Examine the interaction between a business operation and natural surroundings • Can include: – Emissions to air – Land and Water – Legal Constraints – Effects on the Neighbouring Community – Landscape and Ecology – Public's perception of an organization’s operation • A Diagnostic Tool ENVIRONMENTAL AUDIT
    29. 29. • Enables environmental problems and risks to be anticipated and proper responses to be planned • Demonstrates that an organization is aware of its impact upon the environment • Provides increased awareness amongst key stakeholders • Develops more efficient resource use and financial savings ENVIRONMENTAL AUDIT Why an Environmental Audit ?
