Renewable energy in developing countriesRenewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. However, since 2015, investment in non-hydro renewable energy has been higher in developing countries than in developed countries, and comprised 54% of global renewable energy investment in 2019.
Zero-carbon cityA zero-carbon city is a goal of city planners that can be variously defined. In a narrower sense of energy production and use, a zero-carbon city is one that generates as much or more carbon-free sustainable energy as it uses. In a broader sense of managing greenhouse gas emissions, a zero-carbon city is one that reduces its carbon footprint to a minimum (ideally 0 or negative) by using renewable energy sources; reducing all types of carbon emissions through efficient urban design, technology use and lifestyle changes; and balancing any remaining emissions through carbon sequestration.
OverurbanizationOverurbanization is a thesis originally developed by scholars of demography, geography, ecology, economics, political science, and sociology in thrergence of International Nongovernmental Organizations Amid Declining States. The term is intentionally comparative and has been used to differentiate between developed and developing countries. Several causes have been suggested, but the most common is rural-push and urban-pull factors in addition to population growth.
Education policyEducation policy consists of the principles and policy decisions that influence the field of education, as well as the collection of laws and rules that govern the operation of education systems. Education governance may be shared between the local, state, and federal government at varying levels. Some analysts see education policy in terms of social engineering. Education takes place in many forms for many purposes through many institutions.
