Quantification of Potential Impacts of Urban and Peri Urban Agriculture and Forestry, Sri Lanka on Climate Change Quantification of Potential Impacts of Urban and Peri Urban Agriculture and Forestry, Sri Lanka on Climate Change Presentation Transcript

  • QUANTIFICATION OF POTENTIAL IMPACTS OF URBAN AND PERI URBAN AGRICULTURE AND FORESTRY, SRI LANKA ON CLIMATE CHANGEC. Semasinghe, N. Jayathilake,H.Manthrithilake, K. Jinapala, R. Ariyaratne
  • Climate Change Climate change is caused due to absorption of infrared radiation by green house gases (GHGs) which slows its escape from the atmosphere Main consequences of Climate change are global warming, change in cloud cover & precipitation, melting ice caps & glaciers, reducing snow cover etc It has serious impacts on economy, health & safety, food production and food security
  • Climate Change in Global Picture
  • How it affects Sri Lanka Sri Lanka is an agricultural economic based developing country CC causes change in temp, extreme weather events such as high intensity rainfall followed by flash floods & landslides and extended dry periods causing water scarcity which directly influences crop & livestock production, hydrologic balances, input supplies etc
  • Why urban Agriculture & Forestry(UPAF) Urban areas are more vulnerable to CC due to high population, deforestation and urban heat island effect Urban agriculture is a viable solution as a mitigation measure to CC as well as it contributes to the economical development of the country
  • How UPAF contribute to adapt CC Reduce food miles Reduce fertilizer milesOther advantages ; Green environment Micro climate environment Clean air Aesthetic value Reduce soil erosion Solid waste management
  • How to Monitor Good monitoring mechanism has to be introduced to demonstrate the results of the project has to be done in two folds  To monitor the success of the project  To monitor its impacts on climate change Record maintaining for the Lessons learnt in order to replicate the project elsewhere
  • Monitoring Mechanism1. Impacts on Climate Change  Collect and plot data for at least 10 years of time period  Monitoring indicators are daily temperature, daily precipitation, frequency of flooding an frequency of drought2. Progress of the project  Food ( Qty, Price)  Fertilizer ( cost of fertilizing)  Energy ( bio gas production)  Water resources ( rainwater harvesting,reusing wastewater)  Aesthetic value ( increase in land value & bio diversity)
  • Monitoring Mechanism ctd…3. Other indicators  Solid waste management ( reusing disposable materials such as plastic bottles, vessels etc)  Institutional changes ( in terms of capacity & commitment for planning, implementing and sustaining the project)
  • Quantification of potential impacts of UPAF onClimate ChangeDevelopment Contribution of UPAF to Contribution of UPAF to Indicator to Measureinterventions CC Mitigation and Reduce Food/ Fertilizer/Fuel Adaptation milesFoodDevelopment of Home Temperature, GHG Increase of UPAF food Household income andGardens emissions, Urban heat production and income savings island effect, Heat waves, Monthly expenditure on food Rainfall, C sequestration,Vertical gardens minimize storm water Transporting, storing, runoff refrigerating(cost/ volumes)Introduction of new Food pricesCropping patternsIncrease agro forestry cover Food wasteReuse non-biodegradable Collection/transport of SW Number/extent of dumpsites/solid waste as cultivate vessels cost of collection and disposal(bottles, plastic bags, etc.) of SW Sun light intensity meterFresh water fish production Increase in UPAF fish Monthly expenditure on fish(Inland ponds) Transporting, storing, refrigerating fish(cost/ volumes)
