¿Cuál es el nivel de ruido existente Av. Av. 3 de Julio y sus intersecciones entre la calle Ambato y la Y del Indio Colorado de la ciudad de Santo Domingo?, el presente trabajo de investigación tiene como objetivo principal conocer el nivel de ruido existente en este sector de la ciudad, con el fin de determinar el alcance de su afectación y sobre todo sus fuentes, se realizó la evaluación correspondiente de acuerdo con la normativa TULSMA. y Decreto Ejecutivo N° 2393, aplicando la investigación de campo se midió la presencia de ruido ambiental y ocupacional, se requirió del uso de dosímetros calibrados y certificados para obtener información precisa. En esta investigación se estudió estas importantes intersecciones, siendo que, en cuanto a normativa ambiental sobrepasa el nivel tolerable con un diferencial de 10 decibeles en promedio, mientras que en referencia del ruido laboral esta intersección está por debajo de los niveles permisibles con al menos 9 decibeles en promedio, las posibles enfermedades subyacentes más comunes encontradas fueron el estrés, los dolores de cabeza que afectaban principalmente a la población comerciante permanente, y la actividad que mayor emisión de ruido produjo fue el tránsito vehicular, del mismo modo se identificó que el día que se produjo mayor contaminación acústica fue el sábado entre las 11:30 am hasta la 13:00 pm.

La rápida expansión de la frontera agrícola como consecuencia desmesurada de la deforestación y cambios antropogénicos a nivel mundial, es un tema de preocupación por la comunidad científica internacional. Además, frente a una lucha contra el cambio climático por efecto de la ganadería, una de las principales estrategias para la mitigación de gases de efecto invernadero, lo constituyen alternativas sostenibles si uso de productos con alta huella de carbono, revalorizando, además, los recursos locales. En el caso de la zona norte de Ecuador, a pesar de los limitados atributos respecto a gradiente de fertilidad de los suelos, la cría de ganado ya sea de leche y/o doble propósito representa uno de los eslabones más fuertes dentro de la economía de las familias. Por lo tanto, es menester investigar alternativas de producción que nos permitan conservar los recursos naturales dada la fragilidad de estos ecosistemas megadiversos. Mediante este libro se plasma que el uso de sistemas ganaderos convencionales, degradan los recursos naturales con mermas significativas de la productividad, así como bajo réditos económicos. En consecuencia, la implementación de sistemas silvopastoriles como alternativa tecnológica de fácil instalación, es sin duda el camino para alcanzar sistemas ganaderos más eficientes, amigables con el medio ambiente, diversificando además los ingresos económicos de la población.

Climate Justice in Your Classroom
Copyright Year: 2023
Contributors: Anderson-Frey, Johnson, Nuwer, Thompson, Turner, Bertram, Brooks, Olson, Price, and Turner
Publisher: University of Washington

As the inequitable impacts of climate change become more evident and destructive, it is essential for climate and environmental justice, as well as methods of civic engagement, to be taught at a high-level to college-level students. This book provides real examples of how professors at the University of Washington integrated these critical issues into their teachings, both in targeted lessons and as throughlines across an entire course. These samples of how environmental and climate justice have been successfully integrated into higher-level education can serve as both a record of the UW's progress towards centering JEDI at the heart of all students, and as a model for future instructors to use as they work to incorporate more aspects of justice and engagement into their own material.

Every moment of your life will be from the perspective of a single planet—Planet Earth. You were born here and you will die here. This textbook is a guide to your home, to your place in the universe. By taking this course, you will learn about your home planet: how it works and how we know it works this way. This course is a user's manual for planet Earth, with direct recommendations for future generations, such as yourself, to maintain its health and natural wonders. As an astute student, you will be introduced to the theoretical principles of science and of how to defend yourself from the spread of ignorance. You will learn about Earth’s dimensions and motions, as well as how to navigate its surface. You will learn how energy originates from the closest star (the Sun), its Moon, and other sources of energy in the Earth’s active core and how this energy can be used and stored. You will learn basic scientific principles of matter, the makeup of substances that form the field of chemistry. You will examine the planet’s atmosphere, the air that you are breathing as you read this, and how that air is slowly changing. You will explore the vast abundance of Earth’s water, covering the planet in enormous oceans, abundant lakes, and rivers, as well as frozen water locked within snow and ice. You will learn how to predict wind and storms and how climates shift. You will lead your own exploration of the solid interior of the Earth, the composition of mountains, rocks, and dirt. You will learn about life, the most unique feature of the planet. You will explore theories of how life arose and how it has evolved and changed over time, learning that you are of Earth and the story of your own origin on this planet. You will undertake an examination of the great biomes of jungles, forests, and deserts and the life that exists within them. You will survey the important field of biology as you learn about life and its interactions with the planet. In the end, you will come to face the ominous future of your own planet, of the changes that are now occurring. Your planet is not the same as your ancestors, nor grandparents, nor your parents at your age—Earth today is quickly being altered, and you will need to adapt to this change. This course will teach you how to prepare for this change and how to protect the planet from further alteration to the point that it becomes lifeless. This class will be challenging, but with enough dedication and commitment, you will succeed in learning the material. You will cherish the knowledge presented in this class for the rest of your life.
