We develop roadmaps to transform the all-purpose energy infrastructures (electricity, transportation, heating/cooling, industry, agriculture/forestry/fishing) of 139 countries to ones powered by wind, water, and sunlight (WWS). The roadmaps envision 80% conversion by 2030 and 100% by 2050. WWS not only replaces business-as-usual (BAU) power, but also reduces it ∼42.5% because the work: energy ratio of WWS electricity exceeds that of combustion (23.0%), WWS requires no mining, transporting, or processing of fuels (12.6%), and WWS end-use efficiency is assumed to exceed that of BAU (6.9%).

We adopt a theory-based approach to synthesize research on the effectiveness of payments for environmental services in achieving environmental objectives and socio-economic co-benefits in varying contexts.

Existing studies on adaptation to climate change mainly focus on a comparison of male-headed and female-headed households. Aiming at a more nuanced gender analysis, this study examines how husbands and wives within the same household perceive climate risks and use group-based approaches as coping strategies. The data stem from a unique intra-household survey involving 156 couples in rural Kenya. The findings indicate that options for adapting to climate change closely interplay with husbands’ and wives’ roles and responsibilities, social norms, risk perceptions and access to resources.

Fossil fuel subsidies are a key barrier for economic development and climate change mitigation. While the plunge in international fuel prices has increased the political will to introduce fossil fuel subsidy reforms, recently introduced reforms may risk backsliding when fuel prices rebound − particularly if they fail to address the underlying mechanisms that create demand for low fossil fuel prices. Extant literature has mostly focused on the consequences of fossil fuel subsidies, including their economic or environmental impact, and the social contract that make their reform difficult.

Climate change, population growth and rapidly increasing urbanisation severely threaten water quantity and quality in Sub-Saharan Africa. Treating wastewater is necessary to preserve the water bodies; reusing treated wastewater appears a viable option that could help to address future water challenges. In areas already suffering energy poverty, the main barrier to wastewater treatment is the high electricity demand of most facilities.

This book chapter advances SDG 11, 15 and 9 presenting the role of adaptation of buildings in the context of climate change, the consequent implications on buildings in various climatic zones, and the possible strategies that need to be evaluated.

It is no secret to anyone living in Beirut or a similar modern city in a semi-arid tropical country in the summer that their home has become a concrete forest and an urban heat island. Old wood or stone houses and their gardens have been replaced by concrete towers and parking lots, in the name of development. The result is searing summer nights, a drastic loss of insect and avian biodiversity, and a large increase in energy usage for interior climate control. These problems are experienced in rapidly developing urban centers worldwide.

Urbanization is transforming human society in many ways. Besides all the obvious benefits, it also brings negative impacts such as the well-documented urban heat island (UHI) effect and the magnified human heat stress. One way to reduce human heat stress is to increase vegetation density in urban areas, because they can provide evatranspiration and shading benefits. However, given the diversity of tree species and their morphological properties, it is important to understand rationally how different trees regulate thermal comfort.
