  • Innovation in Disaster Risk Reduction Applyng Global Investigations on La Molina Effects
    INNOVATION IN DISASTER RISK REDUCTION APPLYNG GLOBAL INVESTIGATIONS ON LA MOLINA EFFECTS Julio Kuroiwa(1) SUMMARY Disaster Risk Reduction (DRR) globally has mainly been based on reducing the vulnerability of buildings and infrastructures, designing and constructing them more robustly, using, for example, seismic codes of Japan and California, USA, from the 1980s, which have substantially reduced structural damages. However, disaster reduction has lately evolved to disaster risk reduction. By adding risk, it is explicitly including the other risk parameter: hazard. In La Molina, during the Lima 1940, 1966 and 1974 earthquakes, the seismic intensities there were IX MMI while in most of Lima’s built up areas, the intensities were V-VI MMI. The borders of La Molina and Lima areas are separated by only a few hundred meters, but there were large differences in intensity. Those events are named microzonation effects. Inspired in La Molina microzonation effects, from 1966 to 2017, the author carried out field damage survey investigations of 25 important disasters occurred in the Americas, Japan and China, and a few more in Peru of geological and hydrometeorogical origin disasters, including climate change. The two most clear microzonation effects –of the globally investigated disasters– occurred: (1) during the 1985 Michoacan Mexico earthquake, Mw 8.1 USGS, when the peak acceleration was 12cm/s2, at Lazaro Cardenas Port, on stiff soil, close to the seismic epicenter, while in Mexico City (MXC), 350 km from the epicenter, the peak acceleration was 120 cm/s2 on muddy soil at the location of the old Texcoco Lake. The soil amplification was 10 times, in spite of the great distance of MXC from the seismic epicenter.

  • Andean Region, South America
    Andean Region, South America Appeal No. MAA46001 30 April 2010 This report covers the period 1 January 2009 to 31 December 2009. A Bolivian Red Cross volunteer disseminating key community messages for dengue control and response. Source: Bolivian Red Cross In brief Programme purpose: Support the five National Societies in the Andean Region, ensuring closer work with the National Societies, to effectively implement the Inter-American Plan 2007–2011. Programme summary: The International Federation of Red Cross and Red Crescent Societies (IFRC)’s Regional Representation for the Andean Region, based in Lima, continued its activities in 2009 to support the membership needs of the National Societies of Bolivia, Colombia, Ecuador, Peru and Venezuela. This technical accompaniment, in alignment with the New Operating Model (NOM), led to the joint development of country support plans with the National Societies of Bolivia, Colombia, Ecuador and Peru. These plans contribute to guiding regional programme support which reflects national needs and priorities, informed by available capacities and resources and in harmony with global, continental and regional Federation initiatives. National Societies have well received the definition of country support plans, which shows a positive change towards providing more specific and tailor-made support. Progress at the programme level has been maintained, despite resource challenges. Community risk reduction actions have contributed to training more communities and volunteers as well as establishing national and community-based disaster preparedness plans. The Health and Care programme has increased the number of HIV and AIDS actions and Club 25 members; it also has provided and trained National Societies in the use of the Epidemic Control Toolkit and in Health in Emergencies and epidemic control.

  • Bero Architecture PLLC BA915.32.Construction Quality.04512.Doc Some Thoughts on Construction Quality
    B E R O ARCHITECTURE P L L C ARCHITECTURE SUSTAINABILITY PRESERVATION Thirty Two Winthrop Street, Rochester, New York 14607 585-262-2035 (phone) • 585-262-2054 (fax) • [email protected] (email) SOME THOUGHTS ON CONSTRUCTION QUALITY Quality Options Building construction varies in quality. The following list is arranged from modest conventional quality to the highest quality: residential, commercial, institutional, and museum. Residential quality is least expensive, least durable and most susceptible to destruction by natural forces. We urge owners of other than residential buildings (especially organizations planning to own their buildings beyond an individual human life time) to implement at least institutional quality construction and repairs. Conventional Wisdom As day-to-day decisions are made regarding how to repair your building, beware of conventional wisdom. Conventional wisdom is the basis of advice promulgated by suppliers and contractors who are engaged in conventional construction, most of which is residential or light commercial. The fundamental premise is that cost is of utmost importance and durability is secondary. Since average home ownership is reputed to last only seven years, conventional wisdom may be appropriate for many homeowners. But for individuals or organizations planning to preserve a building, replacing sound original materials with short-lived materials is almost always a bad idea, for example, replacing wood windows with vinyl windows. Similarly, use of temporary materials like aluminum flashing and pressure-treated wood is ultimately more expensive than use of more durable materials. When planning repairs and improvements you may wish to seek durability and analyze costs vs. benefits over time, as befits preservation of a significant building.

  • The Potential Role of Cattail-Reinforced Clay Plaster in Sustainable Building
    The potential role of cattail-reinforced clay plaster in sustainable building G. Georgiev, W. Theuerkorn, M. Krus, R. Kilian and T. Grosskinsky Fraunhofer-Institute for Building Physics IBP Holzkirchen, Germany _______________________________________________________________________________________ SUMMARY Sustainable development is a key goal in town and country planning, as well as in the building industry. The main aims are to avoid inefficient land use, to improve the energy efficiency of buildings and, thus, to move towards meeting the challenges of climate change. In this article we consider how the use of a traditional low-energy building material, namely clay, might contribute. Recent research has identified a promising connection between the reinforcement of clay for internal wall plastering with fibres from the wetland plant Typha latifolia (cattail) and the positive environmental effects of cultivating this species. If large quantities of Typha fibres were to be used in building, the need for cultivation of the plant would increase and create new possibilities for the renaturalisation of polluted or/and degraded peatlands. We explore the topic first on the basis of literature, considering the suitability of Typha for this application and possibilities for its sustainable cultivation, as well as implications for the life cycle analyses of buildings in which it is used. We then report (qualitatively) the results of testing different combinations of clay with natural plant (straw and cattail) fibres for their suitability as a universal plaster, which demonstrate clearly the superior properties of Typha fibres as a reinforcement material for clay plaster mortars. KEY WORDS: clay mortar; life cycle analysis; paludiculture; peatland; Typha latifolia; wetland _______________________________________________________________________________________ INTRODUCTION clay has already been proved as a sustainable building material.
