Social Sciences and landscape analysis: opportunities for the improvement of conservation policy design

This article develops a methodology aimed at generating a systematic social diagnosis of social and natural landscapes. The analytical process is divided into six easily replicable and causatively connected steps. The goal is two-fold: first, to present the inextricable connections between physical landscapes and the communities that occupy them. And second, to provide a fundamental tool to public policy designers that should simultaneously improve social acceptability of conservation policies and policy efficiency and effectiveness. Finally, this methodology is consciously heterogeneous from a theoretical perspective. This article puts together, in fruitful dialogue, contributions from varying places on the social theory spectrum: from political economy to poststructural theory.     

Importance of public information and perception for managing recreational activities in the Peel-Harvey estuary, Western Australia

Surveys of water recreational activities were conducted in the Peel-Harvey estuary. Channels used by recreationists to gain information about water quality, the perception of water quality and resulting behaviour were investigated. This study showed that personal perception, local knowledge and history, absence of warnings and residency were major factors contributing to risk perception and behaviour in this recreational community. Management strategies should take this information into account to achieve maximal outcomes.     

Tropical forests: The policy challenge

Summary Tropical forests are being destroyed faster than ever, the rate having almost doubled during the 1980s. The main agent of deforestation now turns out to be the displaced peasant or landless farmer, sometimes known as the shifted cultivator; that group accounts for more forest loss than the combined impacts of the commercial logger, the cattle rancher and all other better known sources of deforestation. Yet, the over-riding target of conservation efforts remains the minor players in the forest's decline. All too little attention is directed towards the shifted cultivator, and next to nothing is done to address the problem which this group represents. Policy purviews need to be expanded to include the key factor of the shifted cultivator. In turn, it must determined what impels these people to abandon established farming areas in the countries concerned and to migrate into the forests. It appears that these people are driven by an array of forces: population growth, maldistribution of arable lands, inadequate rural infrastructure and lack of government attention to subsistence agriculture. In other words, the source problem is an amalgam of non-forestry factors, and conservationists will not achieve success in safeguarding the remaining forests unless they direct much more emphasis towards these root causes of deforestation.Dr Norman Myers is a consultant in environment and development, a member of this journal's Advisory Board and a regular contributor to the journal (seeThe Environmentalist,8(3), 187–208 and10(4), 243–256).     

Economic and Spatial Impacts of an Existing Reserve Network on Future Augmentation

An optimization model for land reservation was developed that explicitly selects parcels in the most compact or contiguous manner possible while meeting habitat requirements and a budget limitation. The model was used to compare the effects of an existing reserve network on future parcel spatial locations and total cost. Using habitat and land value data from Josephine County, Oregon, it was found that a system of existing reserves created by various policies and overseen by different agencies can decrease future reserve compactness and contiguity, and increase total cost. This work suggests that coordinated planning can result in more efficient conservation efforts for less cost.     

Anatomic correlates of ultrasonographic prenatal diagnosis

In utero sonographic diagnoses from forty-five malformed infants were correlated with their autopsy findings. Fifty-two malformations were diagnosed prenatally in 42 of the patients but 90 additional malformations were not. Nine sonographically diagnosed abnormalities were not confirmed at autopsy. Factors compromising sonographic diagnosis included: limited examinations, small fetal size, timing of examination, oligohydramnios, fetal position, nature of the malformation and unfamiliarity of the ultrasonographer with specific malformation syndromes. In vitro ultrasonography is an invaluable tool of diagnosing congenital malformations but has limitations.     

Results of a questionnaire investigation on the management of environmental issues during conceptual design. A case study of two large made-to-order companies

This paper investigates the current treatment of environmental issues by two companies within the large made-to-order sector. Fifty questionnaires were issued to the design team of each company to assess current practice in the integration of environmental issues with design activities, awareness of environmental issues, awareness of existing environmental design tools and the preferred format for a potential clean design tool.
