1 Intervention Areas Specific action areas (Interest areas) Disasters History (hidrometereological and associated ones) Hazards Maps (flood plains, lanslides, erosion, high temperature,etc) VULNERABILITY MAPS Criterios de definición (microzonoificación, áreas homogéneas) Cualitative assessment Cuantitative assessment

2 Ejemplo de indicadores cuantitativosde evaluación de vulnerabilidad (1) Empleo: horas/h, jornales/ha, US$ Inversión : créditos no pagados, US$/ha no invertido, nº de créditos Areas en producción : has/producto, US$/ha, Tm/producto Productividad :tn/ha, US$/ha Económicos: precios (reales, nominales,constantes) Exportaciones, importaciones: Tn, US$, %PBI (FOB o CIF) Sociales: horas de clase perdidas, fam. Afectadas, viviendas afecytadas (US$/viv) (1) Estos indicadores normalmente se establecen por el equipo de trabajo, en función al objetivo del mismo

13 How the recurrency of ENSO affects the fisheries sector? Extinctio or migration of native and endemic species of coastal fishes and marine invertebrates. Diminishing of exportation volumes from US$ 324' 812,000 in 1997 to 139' 157,000 in 1998. Entry of new tropical species Lack of market supplies and fall down of main human consumption species. Increase of the stock of some commercial fisheries

17 Spatial Incidence of floods (1970-2003) 1970-79 1990-99 1980-89 In the first two decades floods affects the lower zone of the river bain. Flooding has been increasing mainly to areas of higher altitude (middle and upper parts of the river basin) Floods in the upper part of the river basin occurs know at right margin 1970-79 1990-99 1980-89

18 Spatial Incidence of landslides and huaycos (water and mudslides) (1970-2003) 1970-79 1990-99 1980-89 In 1970-79 the events were in the upper river basin. In 1980-89, big areas of the middle part of the river basin were affected. In 1990-99, the most significative problems were in the middle and upper river basin 1970-79 1990-99 1980-89

19 Big part of productive lands in flood risk areas Low lands in flood risk areas Irrigation Infrastructure and croplands in floods areas

20 Highways and bridges associated to mango exportation in high risk flood areas Transportation infrastructure and Energy generation facilities in flood risk areas Nergy generation facilities in high risk flood areas
