Climate adaptation in informal areas in hot arid climates

Abstract This conceptual and exploratory research study investigates, systematically and holistically, climate‐adaptive spatial design interventions for high‐density informal urban areas in hot arid climates, which remain understudied despite their vulnerability to heat stress and the heat‐vulnerable groups populating them. Five streetscape design prototypes are proposed that include climate‐adaptive spatial interventions appraised qualitatively with consideration to relevant feasibility matters: land use planning, equity, affordability, mobility, and sense of place. The study shows that there is potential for climate‐adaptive interventions in informal urban areas in hot arid climates, but that these interventions also present challenges. Common climate‐adaptive design strategies can be used to address heat stress in these areas but, for example, increasing vegetation might be challenging due to water stress. As a conceptual study, the findings presented and the discussion raised on feasibility are targeted at opening avenues for future research, and at informing decision‐makers and spatial designers.
