Informal settlements are the most common form of urbanization on the planet, accounting for one-third of the total urban form. It is expected that by the mid twenty-first century, up to three billion people will live in informal urban environments. However, we lack a consistent mapping method to pinpoint where that informality is located or how it expands. This paper presents the findings from a collection of standardized measurements of 260 informal settlements across the world. The main research goal is to identify a standard global sample of informal neighborhoods. It then focuses on mapping urban growth with remote sensing and direct mapping tools. The third stage classifies settlements based on how adjacency features such as development, topography, or bodies of water relate to their growth. The survey of growth corroborates the idea of informality as expanding geography, although at different rates than previously cited in the literature. We found peri-urban location to be a suitable estimator of informal settlement growth. This finding validates the comparison of multiple settlements to understand rates of change of urban informality worldwide. The findings here are vital to resolve important questions about the role of informal urban development in the context of accelerated global population growth.

How are civil society organizations responding to COVID-19’s impacts on informal settlements? In Latin America, civil society organizations have developed a repertoire of collective action, seeking to provide immediate and medium-term responses to the emergency. This paper aims to map these initiatives and identify strategic approaches to tackle the issues, given the strengths of those undertaking the initiative, and the scope, purpose and sphere of intervention. Using direct contact, a survey, and a virtual ethnography with social organizations has allowed us to identify and characterize the initiatives. The repertoire focuses on emergency measures around food security, and pedagogies for prevention, sanitation and income relief at the neighbourhood and district levels. We argue that the civil society response repertoire is diverse in form and resources but limited in scope; meanwhile the urgency of the situation and the mismatch with state action mean that crucial spheres of informality, vital to cultivating grounds for a healthy recovery phase, are being neglected.
