Integration of detailed stratigraphic, sedimentologic and tectonic studies of the Río Cañete Basin with opening and divergence rates of the South Atlantic Ocean, overriding plate velocity, trench migration, subducting age (Fig. 1) etc. and the protracted Mesozoic Farallon Plate oblique convergence parameters provide new lines of evidence to suggest an alternative model for the evolution of the Peruvian margin. These unorthodox model departures significantly from the classic and simplistic Andean Model used in the literature. The western margin of Gondwana experience severe lithosphere extension coeval with arc magmatism since at least Middle Triassic. Actually, only the uppermost Jurassic unit is displayed along the Río Cañete Basin, however, it is important to take into account that northward the Jurassic arc sequence terminates against the accreted Amotape/Olmos Terrain and it over...

The average growth of Peru GDP reached 6 per cent during the 2001-2007 period. However this growth was not in parallel with the microeconomic wellbeing. During this years, the poverty rate decreased 2.7 percentage points in contrast the GDP growth of 27.5 percentage points. As a consequence, searching for high economic growth rates is not enough for reaching a significant decrease of poverty and inequality. In this sense, an effective way might be the promotion of wealth growth initiatives in specific regions with high potential. In order to get a real impact in the poverty reduction it is necessary to change the institutional framework which foster a better environment for the private investment. This article is based on theorical findings and empirical case studies based on local and international experiences. The idea is to suggest ways by which it is possible to link the poor with op...

La variabilidad de las precipitaciones en la cuenca amazónica (CA) es analizada para el período 1964-2003. Este análisis está basado en 756 estaciones pluviométricas distribuidas en todos los países de la cuenca incluyendo datos de Bolivia, Perú, Ecuador y Colombia. En particular, la reciente disponibilidad de datos de precipitación de los países andinos hace posible completar estudios anteriores. Se subraya el impacto de la cordillera de los Andes sobre las lluvias. La mayor precipitación en la CA es observada en regiones bajas expuestas a los vientos húmedos del este, y menor lluvia es registrada en las estaciones de altura y protegidas por las primeras montañas de los Andes de los vientos húmedos del este. Además, los regímenes de las precipitaciones son más diversificados en las regiones andinas que en el llano amazónico. La variabilidad espacio-temporal de las preci...
