  1. Topic 3, Section D Adaptation: Examples and case studies

  2. Learning outcomes In this presentation you will learn about options for adaptation in forest ecosystems through several examples of projects. Topic 3, Section D, slide 2 of 17

  3. Outline • Flood planning and coastal resources in La Ceiba, Honduras (USAID Case Study) • Sensitivity of managed boreal forests in Finland to climate change, with implications for adaptive management • Tradeoff analysis of adaptation strategies for natural resources and water resources in the Philippines • Hydraulic redistribution study in native tree species in an agroforestry parkland of West African dry savanna Topic 3, Section D, slide 3 of 17

  4. Example 1 • Flood Planning and Coastal Resources • in La Ceiba, Honduras Source: http://www.adaptationlearning.net/downloads/USAID_honduras.pdf USAID case study Topic 3, Section D, slide 4 of 17

  5. Introduction Development challenge • To improve economic growth while protecting lives, property, and the environment from climate-sensitive environmental stresses such as storm surges and flooding Core project • ManejoIntegrado de RecursosAmbientales – Integrated Management of Natural Resources (MIRA) is a USAID-sponsored project working in 12 of 21 watersheds in Honduras. One of the focal areas is La Ceiba, where the goals are to improve watershed and natural resource management, while stimulating economic growth. At the time of this case study, MIRA was in the early stages of design and implementation Adaptation objective • To develop infrastructure and strategies to address the city’s serious urban drainage and flooding problems, which are expected to worsen due to climate change and lack of action Topic 3, Section D, slide 5 of 17

  6. Outcomes • Change in local perceptions • major impact on local perceptions of the need to consider climate variability and change during development planning activities • Development of high quality data • the stream-flow data obtained during this project indicates that La Ceiba is at much greater risk of flooding than previously believed • High-quality information is necessary for the development of an appropriate adaptation plan • Identification of ways in which USAID can help La Ceiba cope with its problems of flooding and urban drainage • improving both watershed management and the opportunity for tourism by preventing further deforestation of the Cangrejal watershed • working with disaster management officials to develop a risk management strategy • promoting zoning strategies that limit or prevent development in areas most vulnerable to sea level rise and flooding • improving risk awareness and community preparedness through measures such as a flood warning system • identifying partners to help implement adaptations requiring large capital investment, such as pumping sand to protect against erosion, raising the levees, and developing an urban drainage system Topic 3, Section D, slide 6 of 17

Sensitivity of Managed Boreal Forests in Finland to Climate Change, with Implications for Adaptive Management Topic 3, Section D, slide 7 of 17

  8. Impacts of climate change on forests in Finland • Increased growth (30% from current levels by 2030) • Increased potential cutting drain (67% by 2050) • Changes in species composition (50% increase of Pinus by 2050) Current annual growth (m3 ha-1 year-1) Percentage of change in growth by 2030 Topic 3, Section D, slide 8 of 17

  9. Adaptive forest management options • Main challenges • maintain current productivity • Risks: fire, wind, pests, diseases • manage species composition and provenances • Forest management responses • reduce rotation lengths to manage risks • reduce rotation length for some species and increase it for other species to manage species mixture • use more southern provenances in tree planting • implement efficient risk management plans Topic 3, Section D, slide 9 of 17

  12. Adaptation options for forestry to climatic variability • Adaptation options were identified by villagers in response to climatic variability observed • Below, options identified for forest resources management are identified Topic 3, Section D, slide 12 of 17

  13. Trade-offs (cross-sectoral impacts) for adaptation measures (*) (*) Identified by villagers (+) Positive outcome (-) Negative outcome Topic 3, Section D, slide 13 of 17

  15. An advantage of integrating….. An advantage of integrating trees and crops in dry areas is that the tree roots perform the night-time service of ‘hydraulic redistribution’ – bringing deep water closer to the surface where it can be available to crops Topic 3, Section D, slide 15 of 17

  16. After millet harvest... After millet harvest, there is an upward trend in hydraulic lift, suggesting that after the crop died off, the tree roots bring up more water at night than they themselves use during the day Topic 3, Section D, slide 16 of 17
