Population And Family Health Theory

Introduction

Population & Family Health focuses on the health needs and rights of diverse populations in communities across the world. Critical evaluation, current research activities related to the concept/theories of population and family health, application of the concepts in the current job and usefulness of the concept to the current world will be attempted in the following sections.

Malthusian Crisis

A Malthusian crisis results when starvation ensues as a result of overpopulation. The agricultural produce is not able to keep pace with the population growth therefore leading to starvation, malnutrition and death. In 1798 Thomas Robert Malthus predicted that short-term achievement in standards of living will unavoidably be undermined as

A socioeconomic matrix of vulnerability provides a starting point to understand which livelihoods are most vulnerable to different types of climatic hazards and the extent to which different livelihood activities are affected by different climate hazards. The rows of the matrix corresponds to exposure units such as resources, activities and livelihoods that may be exposed to and affected by climate; while the columns list climatic events, stresses or opportunities to which resources, activities and livelihoods may be exposed. The scores from the impact of climate hazards on livelihood activities can help to determine priorities in responding to hazards. Vulnerability assessments (VAs) help to shape climate change adaptation decisions and define the nature and extent of the threat that may harm a given human or ecological system, providing a basis for devising measures that will minimize or avoid this harm4. However a wide variety of VA approaches can be confusing for practitioners, creating uncertainty about the best way to assess

The theory of epidemiologic transition begins with the major premise that mortality is a fundamental factor in population dynamics. At first, the clearest indication of mortality 's dominant role in population dynamics is implicit in theories of population cycles. Secondly, during the transition, a long-term shift occurs in mortality and disease patterns whereby pandemics of infection are gradually displaced by degenerative and man-made diseases as the chief form of morbidity and primary cause of death. Thirdly, during the epidemiologic transition the most profound changes in health and disease patterns obtain among children and young
