Resource Management and Fertility in Mexico’s Sian Ka’an Biosphere Reserve: Campos, Cash, and Contraception in the Lobster Fishing Village of Punta Allen

This case study examines the link between marine resource management and the contraceptive use among married couples in the lobster-fishing village of Punta Allen, located in the Sian Ka’an Biosphere Reserve, Quintana Roo, Mexico. Several reasons appear to contribute to small desired and actual family sizes, including a medical clinic staff effective in promoting family planning, cooperative and private resource ownership, changing cultural attitudes, geographical limitations to population and economic growth, and a desire to conserve the environment for aesthetic and economic motives.

    Human Population as a Dynamic Factor in Environmental Degradation

    The environmental consequences of increasing human population size are dynamic and nonlinear, not passive and linear. The role of feedbacks, thresholds, and synergies in the interaction of population size and the environment are reviewed here, with examples drawn from climate change, acid deposition, land use, soil degradation, and other global and regional environmental issues. The widely assumed notion that environmental degradation grows in proportion to population size, assuming fixed per capita consumption and fixed modes of production, is shown to be overly optimistic. In particular, feedbacks, thresholds, and synergies generally amplify risk, causing degradation to grow disproportionally faster than growth in population size.

      Family Planning and Resilience: Associations Found in a Population, Health, and Environment (PHE) Project in Western Tanzania

      In this study, researchers define and measure resilience within the context of Population, Health, and Environment programming and quantify the link between resilience and family planning. The study findings support the importance of including FP/MCH as part of integrated projects to enhance resilience.
