  • Creating institutions to meet the challenge of sustainability is arguably the most important task confronting society; it is also dauntingly complex. Ecological, economic, and social elements all play a role, but despite ongoing efforts, researchers have yet to succeed in integrating the various disciplines in a way that gives adequate representation to the insights of each.Panarchy, a term devised to describe evolving hierarchical systems with multiple interrelated elements, offers an important new framework for understanding and resolving this dilemma.

  • Urban Ecology is the study of ecosystems that include humans living in cities and urbanizing landscapes. It is an emerging, interdisciplinary field that aims to understand how human and ecological processes can coexist in human-dominated systems and help societies with their efforts to become more sustainable. It has deep roots in many disciplines including sociology, geography, urban planning, landscape architecture, engineering, economics, anthropology, climatology, public health, and ecology.

  • Through the efforts of a wide array of public and private organizations around the globe, a strong and growing movement is beginning the process of transforming the systems that create the built environment from ones that pay no attention to resources and the environment to a new variety in which these considerations are the pre-eminent criteria for “good” construction. Although dating back only to the early 1990s, there is already ample evidence that the “green building” movement is affecting the design, construction, operation, and disposal of the built environment....

  • Evolution of global technologies has prompted increasing complexity of applications developed in both, the industry and the scientific research fields. These complexities are generally attributed to nonlinearities, poorly defined dynamics and absence of apriori information about the systems. Imprecision, uncertainties and vagueness in information about the system are also playing vital roles in enhancing the complexity of application.

  • This is probably the first study that has used resilience, the adaptive cycle and panarchy as a major part of the conceptual foundation for the work. Resilience (as used here) has been explored in the literature for about 30 years, the adaptive cycle originated about 18 years ago and both have been integrated within the panarchy concept for only a few years.

  • The theory of switched systems concerns hybrid dynamical systems composed of a family of continuous–time subsystems and a switching law, orchestrating switching between these subsystems. Systems of this class have been identified in many natural and man– made systems, and are recently widely studied by control theorists, computer scientists, practicing engineers and others.

  • Contemporary interest in food is not confined to pleasure in its consumption, but extends in every direction: to its economic importance, the semiotics of food taste, the dangers of food additives and the politics of food security. We live in societies as dominated by food preferences as by sexual preferences, as obsessed about eating too little as by eating too much. In addition our interest in food is associated, for good and evil, with our interest in ‘nature’.

  • What is the nature of Nature? Is it harmonious and graceful? Is it divine and providential? Is it cruel and wild? These days, answers to the question 'What is the nature of Nature?' often reverberate with claims of natural unity: every living thing in nature, and this includes humanity, is united. The unity of nature idea appears in many different forms; in the speeches of environmentally conscious politicians, in the academic writings of scientists, in the sermons of theological leaders, and in the slogans of social activists.
