Governing sustainable coastal development: The promise and challenge of collaborative governance in Canadian coastal watersheds

Over the past three centuries, the story of Canada's coasts has turned from one of resource abundance to depletion, and from the establishment of new settlements to declining populations, economies, and ways of life in many coastal communities. This article explores the potential of collaborative governance for rerouting coastal development onto a more sustainable path. A cross‐case analysis of three coastal watershed governance examples demonstrates that the primary outcomes of these efforts to date have been building governance capacity and slowing—rather than reversing—social‐ecological decline. Challenges include resistance and rigidity within existing policy systems, rivalries and differing perspectives among actors, and cultures that favour exploitation over stewardship and specialization over integration. Leadership and relationships are key factors in achieving sought after outcomes and overcoming resistance to new approaches. Culture and commitment to place can be significant enablers, often personified in a small number of instrumental leaders who link actors across and within multiple scales. Learning and adaptation, and willingness and capacity to share knowledge, resources, responsibilities, and accountability are required if collaborative governance models are to advance sustainable coastal development and foster significant change.

Gouverner le développement durable du littoral : promesses et défis de la gouvernance collaborative dans les bassins hydrographiques côtiers canadiens

L'histoire du littoral canadien a changé de perspective au cours des trois derniers siècles : allant de l'abondance des ressources à l’épuisement, et de l’établissement de nouvelles colonies au déclin des populations, des conditions économiques et des modes de vie dans de nombreuses communautés côtières. L'objet de cet article est de poursuivre une exploration du potentiel de la gouvernance collaborative pour remettre le développement côtier sur une voie durable. Une analyse croisée de trois exemples de gouvernance côtière de bassins hydrographiques montre que les efforts déployés jusqu'à ce jour ont permis de renforcer la capacité de gouvernance et de freiner – plutôt que d'inverser – le déclin social et écologique. Les défis à relever incluent la résistance et la rigidité propres aux systèmes politiques actuels, les rivalités et les points de vue divergents entre acteurs, et les cultures axées sur l'exploitation plutôt que l'intendance et sur la spécialisation plutôt que l'intégration. Le leadership et le réseautage constituent des éléments essentiels pour atteindre les résultats escomptés et surmonter la résistance face aux nouvelles approches. La culture et l'attachement local peuvent servir de catalyseurs importants souvent incarnés par un groupe restreint de meneurs qui nouent des relations entre acteurs sur de multiples échelles d'intervention. Autant l'apprentissage et l'adaptation que la volonté et la capacité de partager les connaissances, les ressources, les responsabilités et la reddition de comptes sont nécessaires afin que les modèles de gouvernance collaborative puissent promouvoir le développement durable des zones côtières et produire un changement en profondeur.     

Removal of Rock Art Affected by the Raising of the Clanwilliam Dam Wall,Western Cape Province,South Africa: Techniques and Procedures

The commissioning by South Africa’s Department of Water and Sanitation of a new and higher wall for the Clanwilliam Dam will increase dam storage and provide additional water for emerging and existing commercial farmers. But there is a cost to South African heritage. The raising of the wall will flood 27 rock art sites as well as other archaeological and historical resources. In partial mitigation of this impact on heritage the removal of particular pieces of rock art was approved by Heritage Western Cape, the provincial heritage agency. This report focuses on the removal process and techniques used to cut out three pieces of rock art under the management of PGS Heritage between 18 April 2016 and 7 May 2016 from the sites designated CDE02 and CDW10. Publication of the techniques used and the procedures followed will add to the sparse literature on rock art removal and increase the accessibility and availability of information about the removed stones.     

Participatory Augering: A Methodology for Challenging Perceptions of Archaeology and Landscape Change

Public engagement is a significant feature of twenty-first-century archaeological practice. While more diverse audiences are connecting with the discipline in a multitude of ways, public perceptions of archaeology are still marred by stereotypes. Community excavations of ‘sites’ to discover ‘treasures’ which tell us about the ‘past’ overshadow other forms of public research output and hinder the potential of the discipline to contribute to contemporary society more widely. This paper proposes participatory augering as an active public engagement method that challenges assumptions about the nature of archaeological practice by focusing on interpretation at a landscape-scale. Through exploration of recent participatory augering research by the REFIT Project and Environmental Archaeologist Mike Allen, this paper demonstrates how the public can contribute to active archaeological research by exploring narratives of landscape change. Evaluation of the existing case studies reflects the potential of the approach to engage audiences with new archaeological methods and narratives which have the potential to transform perceptions of the discipline and, through knowledge exchange, drive community-led contributions to contemporary landscape management.     

Constructing Water Shortages on a Huge River: The Case of Shanghai

Shanghai is located on the world's third largest river (by volume). Yet it faces the risk of shortages of drinking water. Many decisions and environmental characteristics have contributed to this threat. First, Shanghai has become dependent on water brought into the municipality by rivers. Second, it has become increasingly reliant on water from the Changjiang (Yangzi River), principally in order to control the levels of pollution in the water that enters its treatment plants. Third, for reasons associated with inter‐provincial administrative arrangements, the city's water intakes are located within the municipality, within the estuary zone and subject to tidal intrusions of salt water. Fourth, at high tide and when the Changjiang's discharge is low, salt intrudes far into the estuary, beyond the current water intakes. If sea levels rise, these intrusions will become more pronounced. Fifth, large‐scale central government infrastructure projects (such as dams and the South‐North Transfer) are altering the hydrological characteristics of the river. Such projects raise the probability of salt water intrusions into the water intake zone. The Shanghai and central governments have thus made a series of decisions that, taken together, have led the municipality to rely on a source of drinking water that is increasingly unreliable and subject to the risk of shortages due to salt water intrusions. Why these decisions have been made – independently – is an important problem for those who would understand the provision of water for cities and the practical efficacy of Chinese governance systems.     

Movement of Garden Plants from Market to Bushland: Gardeners' Plant Procurement and Garden‐Related Behaviour

In Australia, the largest importer of exotic plant species is the gardening industry, and most major environmental weeds originally derive from domestic gardens or nurseries. To provide strategies for weed management, this study aims to clarify two key points on the pathway along which garden plants flow from the market to the natural environment with the help of human activities. These are local residents' procurement of garden plants, and local residents' garden‐related behaviour (e.g. leaving organic materials in reserves). We draw on a survey (382 respondents) among Wollongong (New South Wales, Australia) residents whose property has at least one boundary adjacent to bushland. Frequency analysis and ordinal regression were used. The results indicated that most respondents obtained garden plants, and relevant information, from nurseries but perceived that there was insufficient plant origin information (that is, whether introduced from abroad, native to Australia or local to the Illawarra) to help them make choices. It also indicated that a minority of respondents frequently left organic materials (such as lawn clippings) in reserves neighbouring their garden, and many of these respondents saw some benefits in doing so. This study confirms the significant role of nurseries in gardeners' plant choice, and raises questions about the significance of dumping garden waste.     

Integrating Geomorphological Assessments and Oral Histories in Catchment Management: Implications for the Mulgrave River,Northeastern Australia

The dramatic decline in the integrity of Australian river systems in recent decades has seen the development of landcare and catchment management groups across the continent as the main facilitators of river rehabilitation works. There is growing concern for the need to develop adaptive management frameworks that assist informed decision making through the integration of social and geomorphological knowledge into catchment planning. In the Mulgrave River Catchment of northeastern Queensland, difficult management decisions have to be made with limited access to knowledge of natural processes and baseline geomorphological data. To date management decisions have been based almost exclusively on oral histories that state that point bars are accreting and the river is becoming shallower due to bank erosion. As a result bank stabilisation and removal of sand from within the channel have been recommended in the absence of any geomorphological assessments. This study compares oral histories of river bank erosion in the Mulgrave River with geomorphic evidence to highlight the need for integrated landscape scenario planning. The results of grain size analysis of bank and bed material from 27 locations, involving 47 samples, suggest that bank erosion cannot be delivering sediments to point bars. Furthermore, qualitative analysis of historic parish maps and aerial photographs shows that there has only been moderate bank erosion at three locations along the Mulgrave River since European settlement. The study demonstrates the important role that geomorphological investigations have for catchment management and the need for management frameworks that integrate geomorphological processes and landholder priorities for sustainable river management.     

Disaster management takes to the skies: How new technologies are reconfiguring spatialities of power in desert locust management

This article explores how new technologies – such as drones and satellites – are incorporated into disaster management and questions the implications for power relations between disaster authorities and subjects. This is a critical area of research, as the proliferation of aerial and networked technologies has made their use in disaster management and response more common. Although concerns have been raised about the potential use of aerial and networked technologies in the surveillance and spatial discipline of populations by commercial and government actors, few have considered the implications for disaster management. In response, this article turns to geographical literature on necropower, verticality, and planetary spatialities to analyse technological innovations in responses to desert locust upsurges in Kenya. Drawing from qualitative research carried out between February 2020 and January 2021, we explain how desert locust control operations have shifted from horizontal to vertical to networked and planetary in nature through experimentation with new technologies over the past century. We argue that aerial and networked technologies have led to a volumetric shift in desert locust management and response, giving remote and increasingly automated actors who operate ‘above’ greater power over the life and death of populations ‘below’. In making this argument, we adopt a more-than-human perspective to account for how nonhuman entities and lifeforms shape and are subjected to necropolitical disaster management and responses. We conclude by reflecting on what this analytical approach has to offer the study of vertical and volumetric geographies.     

史前考古学中的术语问题

术语是学术研究中的一套具有自身特征的符号系统,术语的规范化是学术研究得以发展的重要前提。在我国的史前考古学界,这个问题不太受人重视,其结果便是近年来出现了一些不规范的术语,研究工作也出现了一些混乱的现象。本文呼吁学界重视史前考古学术语的规范化管理问题,认为这是学术研究规范化的一项基础工作。     

Partition,consociation, border‐crossing: some lessons from the national conflict in Ireland/Northern Ireland

ABSTRACT. Outlining Ireland's long history of ethno‐national conflict, and the recent protracted ‘peace process’ in Northern Ireland, contextualises a critique of the problems underlying such conflicts, and the difficulties in transforming externally imposed conflict management into self‐sustaining conflict resolution. It is argued that the problems and difficulties are deeply rooted in a thoroughly modern complex of nationalism, ethnicity, sovereignty and representative democracy. These are knotted together in a common denominator of territoriality, and the nub of the problem is the ‘double paradox’ of democracy's undemocratic origins in the present. Territoriality, the use of bordered geographical space, is a powerful and ubiquitous mode of social organisation which simplifies social control. But it can grossly oversimplify and distort social realities, particularly at borders and especially where territory is contested, thereby reinforcing other distorting simplifications typically found in ethno‐national conflicts. In consequence, radical remedies are needed if the problems are to be overcome. Making ethno‐national peace paradoxically calls for more creative border‐crossing conflicts around other issues.     

Adaptive Management for Water Quality Improvement in the Great Barrier Reef Catchments: Learning on the Edge

This paper proposes using an adaptive management approach to achieve water quality improvement in large catchments with multiple diffuse pollutant issues. Adaptive management involves attention to process, and commitment to continually improving knowledge and practice. It also requires an appreciation of differences in understanding of various stakeholders and an ongoing commitment to learning. Based on research with the Burdekin Dry Tropics regional Natural Resource Management group, the paper shows how the acquisition of knowledge about Water Quality Management can be an aim in itself, rather than an activity peripheral to the planning process. To this end, the paper describes the methods used to elicit stakeholders’ understandings, explores the variation in understandings between key stakeholders, and describes a process used to incorporate the various views in an adaptive management framework for managing water quality. The research findings reveal the importance of process and participation for adaptive management and suggest that success can be judged in terms of learning outcomes.
