Las políticas públicas representan el principal eje de acción hacia la seguridad alimentaria, seguridad nutricional o soberanía alimentaria. Es así que los indicadores derivan de estadísticas nacionales y pueden ser utilizados para establecer nuevas perspectivas. El Ecuador es un país megadiverso, cuyo patrimonio natural es la base de su desarrollo...

The objective of this research was to analyze energy security in Ecuador, which is interconnected with water and food security. As a methodology, 21 indicators grouped into the following dimensions were analyzed: availability, infrastructure, energy prices, efficiency, social impact, environment and governance. For each indicator, a cross-sectional...

Agriculture is the principal source for satisfying the growing global demand for food. However, current production patterns and socioeconomic and demographic pressures could lead to an unsustainable, inequitable food supply. Government interventions support technical advances designed to meet future needs following international trends while overco...

Sustainable agriculture seeks to imitate natural ecosystems and be economically and socially viable. Sustainability requires indicators that serve as information tools to understand the environmental consequences of development. In this sense, the Multi-scale integrated analysis of societal and ecosystem metabolism (MuSIASEM) is an analytical frame...

La agricultura sostenible busca imitar los ecosistemas naturales y ser, a la vez, económica y socialmente viable, por lo que es necesario contar con indicadores de sostenibilidad que puedan servir como herramientas de información para conocer las consecuencias ambientales del desarrollo. En este sentido, el análisis integrado multiescala de la soci...

Cocoa (beans) is one of the highest-value crops globally, yet some producer countries still follow ancient ancestral-style production practices, particularly in Latin America. Most of the production system is in the hands of small-scale producers, who have faced significant obstacles to trading their products with large multinationals due to a powe...

In Latin America and the Caribbean, the interrelationships among water, energy, and food are complex, partly due to their development models, which are intensive in their use of these resources. This research aims to recognize and quantify the use of water and energy in food in Ecuador by identifying the main interrelationships, together with their...

Andean countries face development challenges that depend crucially on the governance of land, water, and energy resources. Over the last few decades, international trade and growing food demand have brought ample opportunities to agricultural and economic development. This growth, however, has also exposed the unsolved tensions between water govern...

El Distrito Metropolitano de Quito genera residuos sólidos urbanos de composición orgánica significativa, procedentes de residuos de alimentos, que producen gases de efecto invernadero y contribuyen al calentamiento global y cambio climático. El propósito de esta investigación fue cuantificar el desperdicio de alimentos en hogares de Quito, caracte...

The Metropolitan District of Quito generates solid urban waste with a significant organic composition, from food waste, which produces greenhouse gases and contributes to global warming and climate change. The purpose of this research was to quantify food waste in households in Quito, characterize the metabolism of urban solid waste management in t...

Increasing food demand has led to significant agricultural expansion globally with negative impacts on resources and the environment, a perfect manifestation of the Water-Energy-Food-Environment nexus. Whilst many tools have been developed to understand the complexity of the Water-Energy-Food-Environment nexus most have failed to explicitly conside...

Abstract: In this study, an environmental approach is used to reveal pressures on natural resources caused by food waste and depicted through water, land and energy footprints. The purpose is: 1) to quantify food waste in households in the Metropolitan District of Quito; 2) to determine the environmental pressure of food waste on energy, water and...

Biofuels in Ecuador were born with the purpose of achieving an effective substitution of imports of petroleum derivatives. The objective of this research is to analyze the impact that biofuel production has on water, food, and energy, and its contribution to reducing the growing dependence on fossil fuels in the transportation sector in Ecuador. Th...

The Amazon forest has been characterized as one of the areas with the most extraordinary biodiversity in the world. However, the implementation of public policies throughout history has been one cause of an increasing presence of farmers who exert pressure on resources. The need to determine agricultural frontier growth and document the problem has...

The objective of this article is to analyze the food transport in Ecuador faced with a possible reduction in the subsidy of diesel, taking as a case study the Metropolitan Public Company Wholesale Marketplace of Quito, in order to identify guidelines for the formulation of strategies in the event of a reduction in the subsidy of this fuel.

Our study has to do with the development and validation of a tool that allows the measuring of socially responsible behavior based on five psychological components. The questionnaire was applied to a sample of 160 people from various organizations (ratio of questions vs answers per question-7:1). As a result, we obtained an instrument with 14 items...

La milenaria aspiración de las personas y los pueblos para vivir "bien" se ha manifestado con el paso del tiempo de diversas formas. El arte de vivir fue una preocupación de filósofos de la India, la China y la antigua Grecia, sin embargo, el arte de vivir se presenta de una forma nueva en nuestra civilización caracterizada por la industrialización...

Supporting small farmer livelihoods in fragile, biodiverse regions, such as tropical forests, is a priority for many development agencies and national governments. These regions tend to be characterized by recent human settlements, increasing populations and infrastructure development, as well as competitive land use activities, which exert pressur...
