After a century of major technicaladvance, essentially achieved by and for theindustrialized countries, the evolution of thefood sector in southern countries should nolonger be thought of in terms of a ``headlongpursuit.'' In the present context of demographicgrowth, urbanization, poverty and disparities,environmental degradation, and globalization oftrade, new priorities have emerged, and newethical questions have been raised, mainlyrelated to sustainability and equity. Thispaper analyses these ethical concerns in thefollowing terms: can the model of food sectordevelopment initiated by the industrializedcountries be applied to the entire world on asustainable and equitable basis, given theeffects of this development with regard to theenergy consumed, the changes in dietarybehavior and related nutritional problems, thenew demands in terms of food safety, thequestions of biodiversity, ownership ofknowledge, cultural identities, gender issues,and Man's relationship to food and Nature? 相似文献
Objective: The objective of this study was to identify, critically appraise, summarize, and synthesize evidence from cost-effectiveness analyses (CEAs) of interventions aimed at preventing road traffic injuries (RTIs) in low- and middle-income countries (LMICs) by age group and road users targeted.
Methods: A search strategy was applied to 12 electronic databases for studies published between May 2002 and August 2015 that met prespecified inclusion criteria. Additional studies were identified by contacting authors and searching bibliographies. Included studies were critically appraised against published criteria and a narrative synthesis was conducted including a use of the strength of evidence criteria.
Results: Five studies were included in the final review that reported 9 interventions. Only 2 out of 9 interventions (drink-drive legislation with enforcement via breath testing campaign and combined interventions for reducing RTIs) showed moderate evidence of being cost-effective, whereas the evidence of cost-effectiveness of other interventions was weak. Only 2 interventions (bicycle and motorcycle helmet use legislation and enforcement) were explicitly targeted to children, young people and vulnerable road users such as pedestrians and cyclists. The cost-effectiveness of interventions to prevent RTIs in LMICs ranged from US$4.14 per disability-adjusted life years (DALYs) averted for building speed bumps at the most dangerous junctions that caused 10% of junction deaths in the area studied to US$3,403 per DALYs averted for legislation and enforcement of helmet use by motorcyclists in the World Health Organization (WHO) sub-Saharan Africa region.
Conclusions: Evidence of cost-effectiveness of interventions to prevent RTIs in LMICs is limited, particularly for children, young people, and vulnerable road users. Evaluation of the effectiveness and cost-effectiveness of a larger number of possible road safety interventions in a variety of LMIC settings is warranted to generate the evidence base for effective traffic injury prevention programs. 相似文献
Reporting of CO2 emissions and removals from the landuse change and forestry (LUCF) sector is assessed in this paper based onthe National GHG inventories and the National Communications submittedby the Annex-I countries. LUCF sector is a net sink for 27 countries outof 31 countries and a source for Australia, Estonia, Lithuania and UnitedKingdom. LUCF sector for Annex-I countries, as a group is a net sink of2035 Tg CO2 (555 Tg Carbon). The sink feature is largely due toCO2 removal by the existing forests, plantations and other trees.Forest and grassland conversion (deforestation) is not a major source ofCO2 in the Annex-I countries. Many Annex-I countries have notfully adopted the reporting format of IPCC limiting the comparability andtransparency. Several Annex-I countries have modified the CO2emission/removal estimates for 1990, but have not explained the reasons.Reporting of uncertainty is very limited. The methods adopted andparticularly reporting is inadequate to meet the requirements foroperationalising the Kyoto Protocol articles relevant to LUCF;comparability, transparency and verifiability. 相似文献
Abstract: Priority setting is an essential component of biodiversity conservation. Existing methods to identify priority areas for conservation have focused almost entirely on biological factors. We suggest a new relative ranking method for identifying priority conservation areas that integrates both biological and social aspects. It is based on the following criteria: the habitat's status, human population pressure, human efforts to protect habitat, and number of endemic plant and vertebrate species. We used this method to rank 25 hotspots, 17 megadiverse countries, and the hotspots within each megadiverse country. We used consistent, comprehensive, georeferenced, and multiband data sets and analytical remote sensing and geographic information system tools to quantify habitat status, human population pressure, and protection status. The ranking suggests that the Philippines, Atlantic Forest, Mediterranean Basin, Caribbean Islands, Caucasus, and Indo-Burma are the hottest hotspots and that China, the Philippines, and India are the hottest megadiverse countries. The great variation in terms of habitat, protected areas, and population pressure among the hotspots, the megadiverse countries, and the hotspots within the same country suggests the need for hotspot- and country-specific conservation policies. 相似文献
This paper analyzes the practices adopted and difficulties experienced by Small and Medium-sized Enterprises (SMEs) to transfer socially responsible behaviors to suppliers that operate in developing countries. In particular, a multiple case study was conducted on five Italian socially responsible SMEs. It was found that companies use different strategies as well as diverse management systems and tools to address Corporate Social Responsibility (CSR) issues along their supply chains (SCs). The paper is innovative mainly since few are the existing studies that investigate the CSR practices adopted by SMEs in the SC. Furthermore, it is argued that our research can be helpful to SME managers willing to deal with CSR issues along their SCs, especially when developing countries are involved. 相似文献
