Conservation subdivisions have emerged as a development option for communities wishing to conserve important ecological features and maintain rural character without decreasing housing density. Yet, these alternatives to conventional subdivisions rarely are used. We used logistic regression models to identify variables that predict county level success at adopting an ordinance and having a conservation subdivision built.
Factors determining use of biological disease control measures by the avocado industry in South Africa
Farmers in the northern avocado cultivation areas of South Africa were interviewed concerning their experience and perceptions of biological control. Factors affecting their decision to use biological control programmes as a disease control strategy, were also investigated. Results indicate that educational level, age and land owner status reflect the farmer's decision making ability and the level of commitment to adopt the new technology.
Influence of territorial variables on the performance of wildfire detection systems in the Iberian Peninsula
Wildfire detection systems planning is an essential component of national and regional wildfire management policies. The common resources usually used in wildfire detection are lookout towers, terrestrial mobile brigades, aerial reconnaissance and the general public.
Macroinvertebrate assemblages of peatland lakes: Assessment of conservation value with respect to anthropogenic land-cover change
Small blanket bog lakes can contain many rare and threatened aquatic invertebrate species. Their conservation value, however, is threatened throughout Europe by peat extraction and particularly conifer afforestation, which can compromise the physico-chemical habitat quality of peatland lakes through excessive inputs of forestry-derived dissolved and particulate substances.
Pluri-energy analysis of livestock systems – A comparison of dairy systems in different territories
This paper introduces a generic assessment method called pluri-energy analysis. It aims to assess the types of energy used in agricultural systems and their conversion efficiencies. Four types of energy are considered: fossil energy, gross energy contained in the biomass, energy from human and animal labor and solar energy. The method was applied to compare smallholder low-input dairy-production systems, which are common in developing countries, to the high-input systems encountered in OECD countries.
