This article briefly discusses the evolution of ecosystem approaches, and illustrates the use of ecosystem approaches to assess human health and well-being in a mining context. It discusses the various elements that help distinguish such approaches from other approaches. Well-being here is understood broadly in terms of its “constituents” and “determinants,” of which health is an important constituent...
The importance of infectious disease as a determinant (as well as an outcome) of poverty has recently become a prominent argument for international and national investment in the control of infectious disease, as can be seen in the recently articulated United Nations (UN) Millennium Development Goals (MDGs). Climate variability and land use change have an enormous impact on health in West Africa,...
This article presents the theory and method informing an ongoing study of environmental change and human distress in the Upper Hunter Valley of New South Wales (NSW), Australia. The nature of environmental change in the Upper Hunter landscape over the past two centuries is first described, followed by the preliminary results of a long-term study that aims to investigate the nature of residents’ understanding...
The standpoint from which this article is written is that of development practitioners who work fairly continuously with community transformation processes, and with their peers in many disciplines who are trying to stimulate and support such processes. Drawing on three case examples, the authors put forward four lessons for an ecosystems approach to health development work. First, health and natural...
Since 1990, an interdisciplinary and interinstitutional team of scientists has led a research-intervention initiative examining pesticide impacts on agricultural production, human health, and the environment in the highly commercial potato growing province of Carchi, Ecuador. This article synthesizes the key results of that initiative, analyzes the lessons concerning the process of transdisciplinary...
Ecosystem degradation caused by factors such as improper natural resources management and contamination with agricultural, industrial, and domestic wastes often results in the creation of an unhealthy ecosystem, a main cause for the prevailing poverty and poor health in many parts of rural Egypt. In collaboration with members of the community in some villages of El-Fayoum province, an interdisciplinary...
The introduction of West Nile virus (WNV) to Hawaii could have severe impacts on human health, wildlife health and, as a result, Hawaiis tourism-based economy. To provide guidance for management agencies seeking to prevent the introduction of WNV, we performed a quantitative assessment of the pathways by which WNV could reach Hawaii from North America. We estimated the rate of infectious individuals...
In the late 1990s, community officials in the inner city neighborhood of Central Havana consulted researchers at INHEM (National Institute of Hygiene, Epidemiology, and Microbiology) for assistance in evaluating the effectiveness of interventions that were being undertaken to improve the quality of life and human health amid the severe economic crisis that Cuba was experiencing. The ecosystem approach...
A cultural health index (CHI) for streams was developed in a program of collaborative research involving members of Ngai Tahu (an iwi [tribe] within the South Island of New Zealand) and ecologists at Otago University. The aim was to provide a tool for effective participation of Maori in resource management decisions. Five cultural values are of central importance to the nature of the CHI: mauri (spiritual...
This exploratory study aimed to examine the relationship between fish eating habits, human mercury levels, and mercury levels in fish in three communities of the Napo River Valley, Ecuadorian Andean Amazon, a region without gold mining but with significant deforestation and volcanic soils with naturally high mercury levels. By recognizing the politicoeconomic factors which cause deforestation, the...
The Soils, Food and Healthy Communities project in Malawi uses an interdisciplinary participatory approach to improving child nutrition with resource-poor farmers. The overall research question is: Can legume systems improve soil fertility, food security, and child nutrition? Over 2000 farmers are now experimenting with legume systems in the region. While this article examines the social issues that...
The concept of ecotones as representing the boundary between two ecosystems has proved useful, not only in ecology but also in the epidemiology of zoonoses and vector-borne diseases. The ecotone is a boundary in space between two ecosystems in which many complex processes are at work. Under conditions of man-made environmental change, there are analogous boundaries in time between the two ecosystems...
Effective management of our natural resources requires an understanding of ecosystem structure and function; effectively, an ecosystem-based approach to management. Parasites occur, albeit cryptically, in almost all ecosystems, yet they are usually neglected in studies on populations and communties of organisms. Parasites can have pronounced or subtle effects on hosts affecting host behavior, growth,...
The rapidly expanding population of Sub-Saharan Africa has led to an increased demand for land in which to live and grow food. The process of rural development continues to change the physical landscape, increasing mosquito breeding and biting rates of the chief vector of malaria in Africa, Anopheles gambiae, a mosquito exquisitely adapted for exploiting people. At the same time, development alters...
Population pressures and expanding agricultural and industrial development, with their resulting environmental degradation and demand for water, are likely to increase drought vulnerability on the Canadian Prairies. Coupled with increases in drought expected under climate change, the health and well-being of prairie populations may be compromised. However, little is known about the health effects...
