Learning from the past for sustainability: towards an integrated approach

The task of producing policies for the management of Earth’s natural resources is a problem of the gravest concern worldwide. Such policies must address both responsible use in the present and the sustainability of those finite resources in the future. Resources are showing the adverse results of generations of exploitation, and communities fail to see the outcomes of past policies that have produced, and continue to produce, these results. They have not learned from past policy failures, and consequently fail to produce natural resource management (NRM) policies that support sustainable development. ¶ It will be argued that NRM policy makers fail to learn from the past because they do not have a good historical perspective and a clear understanding of the dynamics of the complex human-environment system that they manage. It will also be argued that historians have not shown an interest in collaborating with policy makers on these issues, even though they have much to offer. Therefore, a new approach is proposed, which brings the skills and understanding of the trained historian directly into the policy arena. ¶ This approach is called Applied Environmental History (AEH). Its aims are to help establish an area of common conceptual ground between NRM practitioners, policy makers, historians and dynamicists; to provide a framework that can help NRM practitioners and policy makers to take account of the historical and dynamical issues that characterise human-environment relationships; and to help NRM practitioners and policy makers improve their capacity to learn from the past. ¶ ..

Introduction to Collaborative Conceptual Modelling

Rising populations, consumerism, urbanism, and globalisation are leading to more extensive and tighter feedback connections within the human-Earth system, making it more and more difficult to understand its dynamics and anticipate its response to management actions. The point has now been reached where it is necessary to take a dynamical systems approach in attempts to develop adaptive strategies that can bring human activities into harmony with planetary processesThis item was commisioned by AN

Constructing Influence Diagrams & Causal Loop Diagrams

Causal diagrams, as used in the field of System Dynamics, are important tools for describing the structure of feedback systems. While they cannot be used to infer the dynamics of a system, they provide a powerful way to capture and communicate mental models and other hypotheses about the causes of observed behaviour. The construction of causal diagrams requires an approach that is more disciplined than the usual mind-mapping exercise, while still allowing flexible expression of ideas. The basic ideas described briefly in this guide are intended as an introduction to the art and science of causal-diagram construction. We provide instructions for constructing influence diagrams (IDs) and causal loop diagrams (CLDs)

‘Living in a state of filth and indifference to … their health’: Weather, public health and urban governance in colonial George Town, Penang

This article explores the development of public health infrastructure in George Town, Penang, before the 1930s. It argues that the extreme weather of the tropical climate led to a unique set of health challenges for George Town's administrators, as the town grew from a small British base to a multi-cultural and thriving port. Weather and public health were (and still are) integrally connected, although the framing of this relationship has undergone significant shifts in thinking and appearance over time. One lens into this association is the situation and expression of these elements within municipal structures. During the nineteenth century, government departments were fewer and shared roles and responsibilities. The Medical Department, for example, observed the weather, making connections between rain, drought and the incidence of disease. Engineers asked critical questions about mortality rates from disease after floods. As ideas about climate and health developed and changed, the shift became evident in the style, concerns and proliferation of governmental departments. This article thus considers the different ways in which weather, public health, and town planning were understood, managed and enacted by the Straits Settlements' administration until the 1930s. It will start by exploring the situation facing the settlement's inhabitants, in terms of specific climate and health challenges. It will then consider how these challenges were understood and addressed, why and by whom, and how these elements were repositioned over the period in question.The authors acknowledge a Seed Award (No. 110432/B/15/Z) in the Medical Humanities from the Wellcome Trust in 2016, which supported the research behind this paper.

Eliciting the implicit knowledge and perceptions of on-ground conservation managers of the Macquarie Marshes

Knowledge that has been developed through extensive experience of receiving and responding to ecological feedback is particularly valuable for informing and guiding environmental management. This paper captures the implicit understanding of seven experienced on-ground conservation managers about the conservation issues affecting the Ramsar listed Macquarie Marshes in New South Wales, Australia. Multiple interviews, a workshop, and meetings were used to elicit the manager's knowledge. The managers suggest that the Macquarie Marshes are seriously threatened by a lack of water, and immediate steps need to be taken to achieve more effective water delivery. Their knowledge and perceptions of the wider societal impediments to achieving more effective water delivery have also led the managers to suggest that there may be system feedbacks that are reinforcing the tendency for water agencies to favor the short-term interests of the irrigation industry. Although the managers clearly have certain personal interests that influence their understanding and perceptions, much of their knowledge also appears to have been heavily influenced by their ecological understanding of the wetland's dynamics. This paper highlights that although all stakeholders clearly need to be involved in making decisions about conservation and how resources should be used, such decisions should not be confused with the need for consulting people with the appropriate ecological expertise to help determine the degree to which an ecological system is threatened, the likely ecological causes of the threats, and actions that may be needed to restore and maintain a functional ecosystem

Cool Communities—Urban Density, Trees, and Health

A move towards more compact and climate-resilient cities is being encouraged around the world. As part of these plans, there is a need to manage the potential conflict between increasing urban densities and the extent of tree canopy in cities. Reductions in tree canopy are a major contributor to the urban heat island (UHI) effect, which will act to reduce rather than increase climate resilience in many cities. A systems thinking approach called Collaborative Conceptual Modelling was used to study the interaction between urban infill, tree canopy, and human health in Perth, Australia. The results indicated that under current planning policies and development practices, the behaviour of the system is dominated by the drive towards higher housing densities. While this may result in the attainment of urban infill targets, it is likely to lead to a reduction in tree canopy, higher temperatures, and a decrease in a range of other benefits provided by trees. Recommended actions to overcome this behaviour were determined by the identification of leverage points in the system. These included a shift to a sustainable development paradigm that places greater value on the environmental and social benefits provided by trees and a greater emphasis on a climate-resilient future. Market and legislative mechanisms should be integrated into the city’s greening strategy and development plans to ensure the protection of existing trees and the inclusion of new trees on public and private land.This research was funded by CSIRO Urbanism, Climate Adaptation and Health Research Cluster.

The role of public health dietary messages and guidelines in tackling overweight and obesity issues

Overweight and obesity in Malaysia pose serious threats to health. Prevalence has escalated to alarming levels in recent decades despite a multitude of dietary public health messages geared toward obesity prevention and health promotion. Gaps between health messages, messengers, and the public must be identified and closed to effectively combat obesity and overweight. This review article aims to examine dietary public health messages, guidelines, and programmes for the prevention of obesity in Malaysia, and explore potential reasons for the continued rise in prevalence. Dietary public health communication in Malaysia has progressed and improved substantially over the years. However, most messages have been designed for a general audience, with little consideration of differences in physical, social, cultural, and environment backgrounds, and varying levels of comprehension. We offer several recommendations to increase the effectiveness of dietary public health messages in fighting the obesity epidemic, based on a cross-sectoral, place-based approach that recognizes the complexity of underlying causes of obesity

Salinity in Colonial Irrigation: British India and South-Eastern Australia

Salinity is an environmental phenomenon that affects the world's arid and semi-arid regions, where it causes soil degradation and problems for agriculture. Salinity began to attract serious attention in the irrigated districts of the Murray Valley in south-eastern Australia in the 1960s. However, observations that the south-eastern Australian landscape was affected by naturally occurring salts predates this period of awareness by more than half a century. Drawing on documentary history, the present paper reveals what soil chemists in New South Wales in the 1890s already understood of the potential dangers of salinity. These scientists were aware of the experience of their colonial colleagues in British India, where the seriousness of the problem had been recognised by the 1870s. Using evidence from India and south-eastern Australia in the nineteenth and early-twentieth centuries, the paper outlines the opposing worldviews of scientists and engineers in New South Wales about the potential dangers of intensive irrigation. It offers an explanation as to why that understanding was insufficient to prevent the growth of the problem

Ignoring the signals: irrigation salinity in New South Wales, Australia

From antiquity the problems of salinisation appeared with the introduction of irrigation in the Mediterranean basin. Times of abundant harvests were followed by periods of declining yields due to sterilisation of the soils. In the nineteenth century, British India and the United States of America had to face similar problems. The experiences in these two countries provided understanding of the problems of salinisation of irrigated soils. In south-eastern Australia salinisation occurred shortly after the Mildura irrigation settlement was established in Victoria in 1887. By 1906 the New South Wales government began plans for Australia's first intensive irrigation development: the Murrumbidgee Irrigation Scheme. In this paper I examine how the historical signals from overseas and Victoria were ignored, and how rising water tables, waterlogging and salinity followed the development
