Synopsis (short abstract) This report examines how forests contribute to or suffer from disasters. Three events are examined: the tempest Gudrun (Sweden, 2005); the Tohoku earthquake and tsunami (Japan 2011); and the 2017 firestorm in Chile. Forests are “victims” of disaster when unable to provide services required by society and cannot recover within a relevant timeframe. Trees damaged may host insect pests that may kill healthy trees or become fuel for forest fires. Fallen trees also damage infrastructure. Extreme events can change the cultural and economic life of small states/islands and/or cause the breakdown of societal services. Disasters affect timber supplies, distorting market functioning. Damaged timber is susceptible to attack from insects and fungi, quickly losing value, and insect attacks may spread to healthy trees. Forests can mitigate disasters by e.g. reducing the intensity of tsunamis or stabilizing slopes. Single trees may become important refuges for people during floods. Key messages include: • Responses require planning and training to enable efficient response also in the absence of key personnel. • Information about the location of critical resources is important, e.g. key staff, forestry equipment, access routes, and timber storage sites. • It is impossible for many small countries to be resilient on their own. Development of regional response capacity is desirable, e.g. pools of qualified operators, equipment resources, and training. • Salvage timber is a resource and an economic asset. Planning on the use of forest resources after disasters is rarely undertaken, and policies or regulations covering this type of use are often missing. • Salvaging timber is dangerous and requires training.

    Waves of hope. Report of the regional coordination workshop on rehabilitation of tsunami-affected forest ecosystems: strategies and new directions 2005

    In an instant the 26 December 2004 tsunami devastated the lives of millions living in the coastal communities of the affected countries. FAO has taken on the task, together with other international and national organizations, in fielding experts to assess the damage and identify critical needs. In the process it has become evident that many organizations are working without the benefit of exchanging information and lessons learned, collaborating fully or coordinating effectively. To help remedy these gaps, FAO organized the above workshop in Bangkok, Thailand from 7 to 8 March 2005 to enhance rehabilitation efforts in the tsunami-affected areas through better coordination of national, regional and international agencies involved in forest rehabilitation and management of the affected areas. The report includes an outline of the critical issues identified, a common vision and principles that should guide forest related rehabilitation and reconstruction efforts, recommendations for stren gthening coordination efforts in the region and summaries of the technical presentations and discussions.

    Hunga Tonga-Hunga Ha’apai eruption and tsunami 2022 – Damage and loss in the fisheries and aquaculture sector

    The Hunga Tonga-Hunga Ha’apai undersea volcano in the Kingdom of Tonga erupted on 15 January 2022 at 17.10 hours local time in a blast that was felt across the world. As a result of the eruption, the Government of Tonga declared a state of emergency on 16 January 2022. The eruption resulted in two events with potential impacts on agriculture livelihoods and all agriculture sub-sectors (crops, livestock, fisheries and aquaculture, and forestry): a volcanic ash cloud and a tsunami. The Ministry of Fisheries (MoF) in Tonga released an initial damage report on 1 February 2022, with a focus on damage to fisheries assets covering small-scale, tuna and snapper vessels, and their engines and gear. The total estimated damage for the fisheries and aquaculture sub-sector was TOP 10.85 million (USD 4.932 million). This report complements the MoF damage report, with an emphasis on associated losses in the fisheries and aquaculture sector as a result of the volcanic ash cloud and tsunami events.

    The December 2004 Indian Ocean tsunami killed approximately 300,000 people and affected the livelihoods of two million people. The disaster represented FAO’s biggest emergency challenge to date, requiring a more varied response and more technical assistance than any previous FAO relief and recovery operations.
