De la gestión de riesgo de desastres a la gestión para el desarrollo sostenible: enfoques conceptuales.
(Universidad del Zulia, 2022-09) Javier-Silva, Luz Alexandra; Portuguez-Maurtua, Marcelo; Chávez-Juanito, Yuli Anabel
Los desastres son hechos imprevisibles que afectan el adecuado funcionamiento social. De acuerdo a la perspectiva que se asuma, estos pueden ser de origen natural, antrópicos o una correlación de fuerzas entre ambos elementos, siendo un proceso de quiebre, donde se producen pérdidas materiales e inmateriales, llevando a una crisis generalizada que afecta las estructuras sociales desde sus cimientos y, en muchas ocasiones, es perdurable en el tiempo. En virtud de lo anterior, el artículo analiza los lineamientos teórico conceptuales de los desastres, en interacción con los postulados de la gestión de riesgos de desastres, entendidos como una serie de estrategias que permiten encarar las vulnerabilidades ante los fenómenos de la naturaleza. Implica la atención internacional, el apoyo hacia la comunidad, así como avanzar hacia la construcción de un modelo de gestión pensado para la sustentabilidad. Gestionar para el desarrollo sostenible, es hacer frente a los problemas medioambientales y humanos, planteando la equidad y justicia social, ideas cónsonas un modelo incluyente e interdisciplinar, con prospectivas hacia futuro.

Inadequate solid waste management causes risks to the environment. This is exacerbated when local governments fail to conduct a relevant environmental risk assessment. The objective of this research was to evaluate the environmental risks of clandestine solid waste disposal sites on the banks of the Sicra and Opamayo rivers in the district of Lircay in the department of Huancavelica, Peru. For the collection of spatial information, the location of clandestine dumps was identified. Seventeen points were mapped in the urban area of Lircay. The estimation of severity and environmental risks was carried out according to the UNE 150008:2008 standard and the Peruvian Environmental Risk Assessment Guide proposed by the Ministry of the Environment (MINAM). Environmental risk zoning maps were then generated. Finally, the result of the environmental risk focused on 4 points of clandestine dumps in medium environmental risk zones and 5 points of clandestine dumps in high environmental risk zones within these riverbanks.
Water Quality Index and Health Risks in a Peruvian High Andean River.

Water quality in rivers is affected as it passes through urban areas; this situation can be improved with good management of water resources. High Andean rivers require further studies to indicate their quality status. In addition, it is important to estimate the health risks associated with exposure to contaminants in the river water. Therefore, it is proposed to assess the water quality index (WQI) using the National Sanitation Foundation (NSF) model and the health risks in the urban section of the Ichu River in Peru. Six monitoring points were selected in the section of the Ichu River that includes the urbanized part of the city of Huancavelica. The sample was taken during the months of February to April 2021. Critical parameters were analyzed by multivariate statistical analysis as principal components and cluster test. In addition, Pearson’s correlation test was performed, and the water quality status was evaluated using the WQI-NSF model. The Ichu River was of “bad” quality, unfit for human consumption, and confirming the impact of the population on water quality. The WQI-NSF model could be useful for high Andean watercourses suffering from anthropogenic deterioration of quality, with illegal effluent discharges and poor sanitation. There is a high health risk due to fecal coliform contamination from sewage discharges into the river. In addition, the total hazard index indicated that contaminants are causing negative health effects in adult males at a low risk level (risk 2), adult females at a moderate risk level (risk 3), and children at a negligible risk level (risk 1). With the help of this study, an appropriate management plan can be put in place to restore the ecological integrity of the Ichu River
