This paper introduces urban land teleconnections as a conceptual framework that explicitly links land changes to underlying urbanization dynamics. We illustrate how three key themes that are currently addressed separately in the urban sustainability and land change literatures can lead to incorrect conclusions and misleading results when they are not examined jointly: the traditional system of land classification that is based on discrete categories and reinforces the false idea of a rural-urban dichotomy; the spatial quantification of land change that is based on place-based relationships, ignoring the connections between distant places, especially between urban functions and rural land uses; and the implicit assumptions about path dependency and sequential land changes that underlie current conceptualizations of land transitions. We then examine several environmental "grand challenges" and discuss how urban land teleconnections could help research communities frame scientific inquiries. Finally, we point to existing analytical approaches that can be used to advance development and application of the concept.coupled human-natural systems | land change science U rbanization and land change are two global processes with far-reaching consequences. Although the two are tightly intertwined, their literatures and analytical frameworks were largely developed separately. We argue that these parallel but distinct conceptualizations limit progress in these fields and in sustainability science, specifically given the environmental impacts of urbanization on the land system, and associated social and political challenges. The magnitude and accelerating rate of contemporary urbanization are reshaping land use locally and globally in ways that require a reexamination of land change and urban sustainability. Worldwide, urban populations are projected to increase by almost 3 billion by 2050 (1) and the total global urban land area by more than 1.5 million square kilometers-an area three times the size of Spain-by 2030 (2). Urban economies currently generate more than 90% of global gross value added, meaning few rural systems are unaffected by urbanization (3). Given such trends, we must reconsider how we conceptualize the many connections and feedbacks between urbanization and land change processes. To date, a large body of literature has considered the proximate land changes brought about by urbanization, but the more distant land-use implications of urbanization remain underexamined.In climate science, the concept of teleconnections refers to climate anomalies that correlate over large geographic distances. During warm phases of the Atlantic multidecadal oscillation, for instance, the incidence of synchronous wildfires increases in the western United States (4). The virtual shrinking of distances between places, strengthening connectivity between distant locations, and growing separation between places of consumption and production are emerging topics in "telecoupled" human-natural systems (5-7) and tropical teleconnections ...

This chapter reviews current thinking about environment-development issues in the transitional zones between distinctly urban and unambiguously rural areas, known variously as rural-urban fringes/transition zones, or peri-urban zones/areas or interfaces (PUI). Such concerns reflect the growing real-world limitations of traditional concepts of a simple rural-urban dichotomy. Moreover, recent archaeological research suggests that these phenomena may have ancient antecedents. Present-day fringes/interfaces have become intimately bound up with notions of (more) sustainable urbanization and urban development, with different issues and agendas manifested in different geohistorical zones of urbanization. Following an overview of planning issues in (post)industrial societies, the chapter addresses the complexities of changing peri-urban production and livelihood systems in the context of rapid urbanization in poorer countries, distinctive peri-urban challenges of appropriate and flexible planning and development, and the future prospects for enhanced sustainability in this most challenging category of development-environment interfaces. Possibilities for mutual learning between geohistorical regions are also raised.

The Sustainable Development Goals and the New Urban Agenda recognise the role of cities in achieving sustainable development. However, these agendas were agreed and signed by national governments and thus implementing them at the local level requires a process of adaptation or localisation. In this paper, we analyse five aspects that practitioners and researchers need to consider when localising them: (1) delimitation of the urban boundary; (2) integrated governance; (3) actors; (4) synergies and trade-offs and (5) indicators. These considerations are interrelated, and while not exhaustive, provide an important initial step for reflection on the challenges and opportunities of working with these global agendas at the local level. The paper draws on the inception phase of an international comparative transdisciplinary research project in seven cities on four continents: Buenos Aires

In order to address climate/environmental change successfully and sustainably, it is vital to foster collaborative relationships between national, regional and local government institutions. Insufficient attention has been paid to relational dynamics between multiple levels of governance, and related learning networks outside formal government structures, particularly in the context of development imperatives in poor countries. This paper illustrates these issues via an exploration of relations between two contiguous, yet contrasting local authorities in South Africa and between these local authorities and higher government levels and other networks. To date, most progressive local climate change initiatives have been undertaken autonomously and often there are mismatched priorities between different government spheres regarding climate change efforts. The likely implications for the execution of environmental change adaptation actions and the benefits of effective networking are considered in this light and through deploying conceptual insights from multilevel governance, systems approaches to urban governance and other literatures.
