The paper is based on a one-month field study of Ethiopia conducted in early 2011, where local bamboo value chains and their sustainability were investigated through a series of interviews, questionnaires, and site visits with local bamboo stakeholders. The study highlights that many rural communities use bamboo extensively as a building material with widespread applications in wall, roof, ceiling, structural work and scaffolding systems. Ethiopia has a rich diversity of traditional bamboo housing designs, practices and skills. However, we also found that the sustainability of Ethiopian bamboo architecture is under threat from modernization, decreasing availability of bamboo resources, increased rural populations, and lack of adequate processing skills and modern designs. Despite these challenges, our economic analysis indicates that using bamboo for the development of tourist lodges and, or, low-income urban housing offer a financially viable means of developing the bamboo construction sector. Therefore, to ensure sustainable development of bamboo-based construction, the study recommends that Ethiopian Government, with assistance from international development agencies, should 1) continue to integrate bamboo with local building materials and promote a broader range of bamboo construction projects through its urban and rural housing development programmes, 2) prepare building codes and product standards for bamboo housing and construction products, and 3) develop clear conservation and utilization policies for bamboo resources to ensure sustainability of the resource. 2011-01-01T00:00:00Z http://idl-bnc.idrc.ca:80/dspace/handle/10625/51124 Title: Risk estimation of mud flows by heavy rains in a rural population of the central Peruvian Andes Authors: Moreno Tapia, Marco Andrés; Sulca Jota, Juan Carlos; Céspedes Reyes, Luis A.; Trasmonte Soto, Grace Abstract: This study is focused on risk assessment in a rural community in the central Peruvian Andes, associated with heavy rains, which act as the main source for landslides, mud flows and floods. These phenomena are intensified during the peak of the rainy season, January to March in our study’s area. We analyzed an event that occurred in the Puquio river (intermittent river), which when it is activated often results in mud flows into the area, causing damage to roads and housing and putting at risk the lives of the community’s people. This situation worse for the absence of knowledge in the population about the impact of heavy rain on them and for the lack of access to information about this issues too. This study hopes to contribute in understanding these kinds of events to help mitigate their effects. 2011-01-01T00:00:00Z http://idl-bnc.idrc.ca:80/dspace/handle/10625/51123 Title: Extreme meteorological events and risk management in the Andes of Peru Authors: Martínez, Alejandra G.; Takahashi, Ken; Zubieta, Ricardo; Orozco, Raquel Abstract: This contribution presents findings from the ongoing project MAREMEX-Mantaro risk reduction and adaptation to climate change in the Peruvian Central Andes in which the physical and socio economical aspects of extreme meteorological phenomena, such as drought, intense rainfall and frosts, and their impacts are studied at the sub basin level, with emphasis on the most vulnerable population (i.e. those with less access to economic, social and information resources). The main objectives of the project are to strengthen the capabilities for risk management associated with these meteorological events by: researching the physical aspects; developing an integrated risk management and adaptation strategy in collaboration with the local and regional authorities, population, and other institutions; disseminating the results of the study in the population and involving local researchers, students, and research institutes in the development of the study. Research in the physical aspects is aimed at increasing the knowledge of atmospheric mechanisms associated with the extreme events to improve the capability of prediction and mitigation of these events. Also, the general analysis includes the identification of the key players and stakeholders, and the identification and analysis of past events and their impacts on the population. 2011-01-01T00:00:00Z http://idl-bnc.idrc.ca:80/dspace/handle/10625/51122 Title: Assessment of flood hazard in the Central Andes of Peru : HECRAS simulation conducted in Mantaro River valley Authors: Zubieta, Ricardo; Quijano, Julio; Latinez, Karen; Guillermo, Percy Abstract: The Mantaro River valley is located between the west and is a major agricultural region. The valley is constantly affected by floods which cause extensive crop losses. The objective of this study is to assess the floodplain hazard with maximum discharges and at different return periods - River Analysis System). The methodology perform construction of a detailed digital terrain model (DT the frequency analysis, the DTM and the river geometry based on Quickbird and GeoEye satellite imagery used for modeling. The results have allowed us to analyze the floodplain with return period of 1, 10, 25, 50, 100 years, with high accuracy, attributed primarily to the digital terrain model. The results provide the technical basis for an early warning system in the Mantaro Valley. Important information was provided by the valley residents about the flood zones for perform prevention and mitigation purposes. 2011-01-01T00:00:00Z
