Archaeology and Contemporary Dynamics for More Sustainable, Resilient Cities in the Peri-Urban Interface

Understanding of urban fringes or peri-urban interfaces (PUIs) as zones characterised by rapid transitional change and sprawling urbanisation has increased markedly over recent years. Archaeological evidence also illustrates the pivotal role that peri-urban zones once played in the survivability of ancient urban centres. Over the last three decades, urban growth and associated transitional changes have accelerated in most regions, producing major challenges to the development of resilient cities capable of absorbing climatic, economic and environmental shocks. Globalised processes of industrialisation and market interdependence have remoulded urban fringes, bringing increased environmental impacts, including the loss of natural resources and environmental buffers now recognised as essential for urban resilience. Furthermore, ongoing global environmental change (GEC) and increasing socio-economic inequality are generating new priorities as peri-urban zones consolidate, erode and shift outwards. Given the inadequacies of existing frameworks, we advocate a hybrid approach to PUI planning and design that draws on integrated, agropolitan-type perspectives embedded within a resilient, locally appropriate regional-urban focus within broader socio-spatial and geo-economic systems. Diverse historical and contemporary examples inform the discussion of the PUI planning and design and the identification of policy recommendations for a hybrid planning approach based on adaptive capacity and resilience.

Governmental and regulatory aspects of irrigated urban vegetable farming in Ghana and options for its institutionalization

This chapter serves as an introduction to the book and provides brief information about urbanization in West Africa, and in Ghana in particular, the general role of urban agriculture and the common use of polluted irrigation water. It describes our focus on irrigated smallholder vegetable production and our understanding of the terms ‘urban‘, ‘peri-urban’ and ‘wastewater’. The chapter reflects on some of the key challenges of the farming system, its dynamic and resilience. It also gives an overview on the structure of the book, the origins of the data and the main objective of this publication.This chapter examines key institutional issues that are important to the recognition and sustainability of irrigated vegetable farming in Ghanaian cities. It assesses the informal nature of the business and examines current roles being played by relevant agencies directly or indirectly linked to urban vegetable farming and urban wastewater management. The chapter also looks at relevant bylaws, strategies and policies that have implications for the recognition of informal irrigation and/or the adoption of safety measures for risk reduction in irrigated vegetable farming. It also suggests options to facilitate the institutionalization of irrigated urban agriculture.This chapter examines key institutional issues that are important to the recognition and sustainability of irrigated vegetable farming in Ghanaian cities.
