Ensuring sustainable consumption and production pattern in Africa: Evidence from green energy perspectives

Aligning to the 2030 United Nations Sustainable Development Goal (SDGs) 12, we investigate the role of renewable energy in achieving sustainable consumption and production pattern in Africa. This study addresses the question: whether the use of renewable energy helps achieve production and consumption patterns free from environmental degradation? We use panel data on 14 African countries from 2002 to 2014 and a robust econometric approach such as panel corrected standard error (PSCE), instrumental generalized method of moment (IV-GMM), and quantile regressions.

Are abundant energy resources and Chinese business a solution to environmental prosperity in Africa?

Africa is abundantly endowed with oil and mineral resources and investment (Habiyaremye, 2020; Zakari and Khan, 2021). However, the region has failed to transform this ample advantage for environmental prosperity. This study centers on the influence of energy resources, Chinese investment, and trade in Africa on the environmental quality of the 40 SSA countries. To achieve this objective, we applied Panel Driscoll-Kraay Standard Errors (PDSE) and System-Generalized Method of Moment (S-GMM) estimators for yearly data spanning the period of 1992–2018.

Asymmetric impacts of foreign direct investment inflows, financial development, and social globalization on environmental pollution

This study examines the impacts of social globalization, foreign direct investment inflows, and financial development on environmental pollution in the context of a globally-representative sample of 107 countries. Unlike previous studies in the literature that have focused primarily on examining individual indicators of environmental degradation, a holistic index of environmental degradation is used in this current study.

Impact of the informal economy on the ecological footprint: The role of urban concentration and globalization

The informal economy represents about a third of world output, thus, generating serious challenges for attaining environmental sustainability. Although there are several indicators of environmental sustainability, the ecological footprint is the most holistic proxy for the capturing the state of environmental degradation. Hence, this research examines the impact of the informal economy, urban concentration, and globalization on the ecological footprint during 1990–2018 period.

Análisis del impacto de la Ley Orgánica para la Promoción del Trabajo Juvenil, Regulación Excepcional de la Jornada de Trabajo, Cesantía y Seguro de Desempleo, sobre el desempleo juvenil en Ecuador

Youth unemployment is one of the main problems facing the globalized world, therefore, the present research focuses on evaluating the impact on youth unemployment of the Organic Law for the Promotion of Youth Work, Exceptional Regulation of Working Hours, Unemployment and Unemployment Insurance (LOTJ) passed in 2016. Control variables referring to the social, economic, demographic and cultural conditions faced by young people aged 18 to 26 during the period 2007-2020 are included.

Análisis sobre la incidencia de la deuda pública en el crecimiento económico de Ecuador durante el periodo 1990-2019

El presente estudio tiene como objetivo evaluar el impacto de la deuda pública sobre el crecimiento económico de Ecuador. Tomando en cuenta que la literatura en su mayoría demuestra que el excesivo endeudamiento público compromete el desempeño económico de los países en el largo plazo, por ello se aporta con evidencia actualizada sobre este tema. Con base a esto se utiliza econometría de series de tiempo implementando modelos de mínimos cuadrados ordinarios (MCO), un modelo de vectores autorregresivos (VAR) y técnicas de cointegración y causalidad.

Influencia de la Renta de Recursos Naturales y la Inversión Extranjera en la Degradación Ambiental de Ecuador [Influence of the Rent of Natural Resources and Foreign Investment in the Environmental Degradation of Ecuador]

In Ecuador, the income obtained from the exploitation of natural resources, especially hydrocarbons and minerals, have been consolidated as the basis of economic development, in turn, the lack of economic and technological resources, as many of the developing countries development, have caused these activities to be concessioner to foreign companies, causing a conflict of interest in which the economic benefit has exceeded environmental sustainability.

Mathematical Model and Experimental Analysis of a Solar Dryer with Parvati Geometry for Coffee Beans

This article reports a mathematical model with experimental measurements of a novel solar dryer named: Parvati Solar Dryer (PSD), which consists of a double angle linear collector and a cylindrical drying chamber with a translucent surface. Semi-theoretical and empirical thin-film models were evaluated to select the one with the best fit (higher coefficient of determination R2 and lower mean square error RMSE) in terms of the humidity ratio MR and taking into account that the drying chamber temperature does not exceed 35 ℃ to maintain the quality of the coffee.

Statistical Analysis of Villonaco Wind Farm Annual Energy Production

The Villonaco Wind Farm is located between coordinates 693030 E 9558392 N and 693526 E 9556476 N in the province of Loja in southern Ecuador. It is the first wind farm in continental Ecuador, with a capacity of 16.5 MW and a location of roughly 2720 m above sea level in rugged terrain, which is especially relevant compared to others wind farms in the global context. This paper presents a statistical analysis of the Annual Energy Production of the Villonaco Wind Farm in the period from 2014 to 2018.
