The time series of water level Titicaca Lake (TL) was compared to the Pacific Decadal Oscillation (PDO) and El Ni?o/Southern (ENSO) indexes between 1914 2014 1969 2014, monthly daily, respectively. Results indicate TL decreased (increased) during positive (negative) PDO phases. ENSO phase results were similar. Positive phases yielded negative (positive) precipitation anomalies concomitant decre...

Interesting landforms created by an ancient network of earthworks are shown, using Google satellite imagery enhanced by an image processing. This network covers a large part of the land near the Titicaca Lake. Satellite images clearly display the slopes of hills criss-crossed with terrace walls and the surfaces of the plains covered with raised fields, indicating that this was once a highly pro...

Se aplicó enfoque cuantitativo, mediante método valoración contingente, se desarrolló modelo “Diferencia en función utilidad indirecta” con probabilidad logit para visitantes, formato encuesta dicotómico doble límite. La población est...

La cuantificación de parámetros fisicoquímicos y microbiológicos es fundamental para definir la calidad del agua, pero el entendimiento las relaciones comportamiento estos parámetros, contribuyen a estado trófico ambiental los ecosistemas acuáticos. En este contexto, objetivo estudio fue determinar entre agua bahía interior lago Titicaca en ciudad Puno-Perú, aplicando técnica árboles predicción...

The Altiplano region of the South American Andes is marked by an inhospitable climate to which the autochthonous human populations adapted and then developed great ancient civilizations, such as the Tiwanaku culture and the Inca Empire. Since pre-Columbian times, different rulers established themselves around the Titicaca and Poopo Lakes. By the time of the arrival of Spaniards, Aymara and Quec...

Abstract Quinoa ( Chenopodium quinoa Will.) is an annual herbaceous Andean plant. In recent years there a growing interest on it due to its high quality as food, wide adaptation agroecological conditions and resistance different abiotic stresses. this work, we evaluate the growth pattern of plants cv. ‘Titicaca’, subjected levels salinity, focusing leaf production nutrient content. sense, resul...

The increase of human interventions and developments are modifying the land use/land cover (LULC) global landscape, thus severely affecting water quality rivers lakes. Appropriate management effective policy required to deal with problems surface contamination around globe. However, spatiotemporal variations its complex relation (LC) changes, challenge adequate resources management. In this stu...
