What is public health? To some, it is about drains, water, food and
housing, all requiring engineering and expert management. To
others, it is the State using medicine or health education and
tackling unhealthy lifestyles. This book argues that public health
thinking needs an overhaul, a return to and modernisation around
ecological principles. Ecological Public Health thinking, outlined
here, fits the twenty-first century's challenges. It integrates
what the authors call the four dimensions of existence: the
material, biological, social and cultural aspects of life. Public
health becomes the task of transforming the relationship between
people, their circumstances and the biological world of nature and
bodies. For Geof Rayner and Tim Lang, this is about facing a number
of long-term transitions, some well recognized, others not. These
transitions are Demographic, Epidemiological, Urban, Energy,
Economic, Nutrition, Biological, Cultural and Democracy itself. The
authors argue that identifying large scale transitions such as
these refocuses public health actions onto the conditions on which
human and eco-systems health interact. Making their case, Rayner
and Lang map past confusions in public health images, definitions
and models. This is an optimistic book, arguing public health can
be rescued from its current dilemmas and frustrations. This
century's agenda is unavoidably complex, however, and requires
stronger and more daring combinations of interdisciplinary work,
movements and professions locally, nationally and globally.
Outlining these in the concluding section, the book charts a
positive and reinvigorated institutional purpose.
