Africa is urbanizing at an astonishing rate. To meet many of the Sustainable Development Goals there will be a requirement for cities in sub-Saharan to plan for, and manage, rapid rise urban population. Green infrastructure has potential provide multiple ecosystem services benefit The general objective this review consolidate research undertaken on green associated African cities. 68 reviewed papers spanned 20 countries included 74 areas. However, only 38% had any carried out them. most represented were regulating provisioning, with supporting getting least attention. Overall was lack in-depth studies all services, especially cultural services. Seven overarching categories barriers challenges sustainable delivery emerged from papers, namely: (i) socio-cultural values, traditions perceptions; (ii) capacity; (iii) governance, planning social inequality; (iv) data and/or case studies; (v) disservices; (vi) spatial trade-offs conflicts; (vii) climate change. These we identified need addressed if future, long-term provision assured.

The Covid-19 pandemic newly brings food resilience in cities to our attention and the need question desired degree of self-sufficiency through urban agriculture. While these questions are by no means new periodically entering global research focus policy discussions during periods crises — last time financial crisis resulting price increases 2008 peri-urban agriculture continue be replaced land-uses rendering higher market values (e.g. housing, transport, leisure). loss priority for land-use planning is a trend with only few exceptions. We argue this essay that development has widely taken place due three blind spots planning. First, limited consideration social ecological vulnerabilities risk-related inequalities inhabitants, shortage among them, face different scenarios change, including climate change or events such as Covid-19. Second, disregard intensified negative environmental (and related social) externalities caused distant agricultural production, well lacking nutrient re-cycling potentials from wastewater) replace emission intensive mineral fertilizer use. Third, lack accounting multifunctionality multiple benefits it provides beyond provision food, insurance values, instance maintenance cultural heritage agro-biodiversity.

Urban land expansion: the role of population and economic growth for 300+ cities

Abstract Global urban populations are projected to increase by 2.5 billion over the next 30 years. Yet, there is limited understanding of how this growth will affect land expansion (ULE). Here, we develop a large-scale study test explicitly relative importance population and Gross Domestic Product (GDP) in affecting ULE for different regions, economic development levels governance types 300+ cities. Our results show that growth, more than GDP, consistently dominant determinant during 1970–2014. However, effect GDP on increases after 2000. In countries with strong governance, contributes growth. We find correlated but relationship varies at developmental stages. Lastly, illustrates good necessary condition ULE.
