Concepts of Human Ecosystems and Stability is a measure of the speed with Human Ecological Interaction which a system returns to equilibrium after absorbing disturbances.

Natural ecosystems - Not perceptibly altered by humans The usefulness of the ecosystem concept is: The actual and historical role of 1.

We can chart and undisturbed by humans. quantify the flow of energy and nutrients and specify the interactions Examples are: Highest parts of mountains, critical for the maintenance of any Undisturbed parts of the seas, lakes, rivers, local population. tundras, etc, and Primeval natural forest 3.

Primer on “Human Ecology as an emerging discipline” in the advent of the establishment of the College of Human Ecology. Apparently, this has become the basis of departmentalizing the College. Conceptual Framework of Human Ecology, CHE, UPLB, 2008 By 2008, in the process of reviewing and improving its human ecology curriculum, the College of Human Ecology came up with a conceptual framework akin to the Systems Model of Human Ecology. 2.

Concepts of CCA and DRR Vulnerability - The propensity or predisposition to be adversely affected. Potential Impact - impacts of climate change are the effects of climate change on Vulnerability to climate change - the natural (e.g. water resources, biodiversity, degree to which a system is susceptible to, soil, etc) and human systems (e.g. and unable to cope with, adverse effects of agriculture, health, tourism, etc). climate change, including climate variability and extremes. a function of the character, magnitude and rate of climate change and variation to which a Adaptive Capacity - the ability of a system system is EXPOSED, its to adjust to climate change (including SENSITIVITY, and its ADAPTIVE climate variability and extremes) to CAPACITY moderate potential damages, to take advantage of opportunities, or to cope with Adaptation - In human systems, the the consequences. process of adjustment to actual or expected climate and its effects, in order to moderate harm or exploit beneficial opportunities. - In natural systems, the process of adjustment to actual climate and its effects; human intervention may facilitate Vulnerability Assessments adjustment to expected climate. Disaster - Severe alterations in the normal functioning of a community or a society due to hazardous physical events interacting with vulnerable social conditions, leading to widespread adverse human, material, economic, or environmental effects that require immediate emergency response to satisfy critical human needs and that may require external support for recovery. Resilience - The ability of a system and its Disaster Risk - The likelihood over a component parts to anticipate, absorb, specified time period for the disaster to accommodate, or recover from the effects of occur a hazardous event in a timely and efficient Interaction of vulnerability and manner, including through ensuring the hazard preservation, restoration, or improvement of its essential basic structures and functions.

Tolbert & Zucker’s Institutional Theory * borrows eclectically from other disciplines - This framework can be used in but is not bounded by any. That is why analyzing efforts to mainstream human ecology is often described as DRM and CCA efforts at various transdisciplinary. levels of governance. Disaster as Politics, Politics as Disaster Disasters are inherently political - They cause ruptures in human society that do no just alter values and norms but also the material infrastructure and other aspects of society. Disasters produce a particular type of politics which he calls as (cosmo)-politics which depicts human relationship with nature and technology as the social organizations are recomposed and altered following a catastrophe. Politics also produces disasters in the absence of preparedness, risk assessment and, in rare cases, extreme events are created for political ends. Human Ecological Lens - The value of human ecology is its ability Humanities in DRM to capture complexity by elevating Asks fundamental questions related to the discussions not just within the academic ethical and political complexity of these disciplines but also reaching out to other ecological issues such as the following: sources of knowledge such as community perspectives in co-producing 1.
