Silvicultural management in maintaining biodiversity and resistance of forests in Europe-the Mediterranean region.

Outstanding features of Mediterranean forest area are highlighted with a special reference to biodiversity and connections with forest management. The naturally originated and anthropogenic progress of the mosaic-like evolution, as well as the man-induced factors and natural constraints are described. The past and present close linkages between management and biodiversity are then analysed by means of a few, outstanding cases typical of the geographical region. The management shift on increasing economically marginal forest area (abandonment) appears to be the major force currently driving connections with inherent and associated biodiversity. The goals following the new-established environmental roles of forests have shifted towards adaptive management, namely the implementation of locally tailored rules in accordance with prominent forest functions. Key priorities to face up to the new scenarios are then discussed. Economic and policy implications are addressed with reference to multipurpose forestry and the related annual flow of outputs. It is shown the role of water-related services, as well the provision of various non-wood forest products and public goods in addition to wood and other traditional forest outputs. Reference is also made to the dualism between the Northern and the South-Eastern Mediterranean countries due to different level of economic development (and pressure of forest resources) together with very different institutional structures, i.e. public ownership in Southern and South-Eastern Mediterranean countries. Nevertheless, the situation is going to become more harmonious in the medium run by growing economic development, the affirmation of local rights on forest resources, globalisation and, above all, rural out migration and exchanges of peoples confirming the traditional role of the Mediterranean Region at cross road of South-North and Eastern-Western cultures.

Socioeconomic and demographic effects of malaria eradication: a comparison of Sri Lanka and Sardinia.

The relationship between disease control, population growth and economic development is examined through a comparison of changes subsequent to malaria eradication campaigns in Sri Lanka and Sardinia. Both islands were similar in terms of malaria morbidity and mortality rates as well as a history of massive malaria eradication campaigns using DDT immediately after the Second World War. The critical comparative distinction is that Sardinia had a much lower population density than Sri Lanka. In both cases, the anticipated effects of malaria control were increased agriculture production in endemic zones coupled with a relief of population pressure in non-malaria areas. This has not happened. Patterns of demographic change, marked by sharp declines in general mortality and accelerated population rates, are similar in both cases. Malaria control has resulted in economic development in neither case, however, and this is explained using ecological and political-economic analyses.

Environmental sub models for a macroeconomic model: agricultural contribution to climate change and acidification in Denmark.

Integrated modelling of the interaction between environmental pressure and economic development is a useful tool to evaluate environmental consequences of policy initiatives. However, the usefulness of such models is often restricted by the fact that these models only include a limited set of environmental impacts, which are often energy-related emissions. In order to evaluate the development in the overall environmental pressure correctly, these model systems must be extended. In this article an integrated macroeconomic model system of the Danish economy with environmental modules of energy related emissions is extended to include the agricultural contribution to climate change and acidification. Next to the energy sector, the agricultural sector is the most important contributor to these environmental themes and subsequently the extended model complex calculates more than 99% of the contribution to both climate change and acidification. Environmental sub-models are developed for agriculture-related emissions of CH(4), N(2)O and NH(3). Agricultural emission sources related to the production specific activity variables are mapped and emission dependent parameters are identified in order to calculate emission coefficients. The emission coefficients are linked to the economic activity variables of the Danish agricultural production. The model system is demonstrated by projections of agriculture-related emissions in Denmark under two alternative sets of assumptions: a baseline projection of the general economic development and a policy scenario for changes in the husbandry sector within the agricultural sector.

[Median age of mortality as an indicator of economic-social and nutritional status].

Mean age of mortality as an indicator of economic development and nutritional state. After a short discussion of nutritional indicators the mean age of mortality of the population of a country is proposed. This is defined as the age as 50% mortality is observed. It is an indicator for social-economic development. There exists a correlation between the proposed indicator and others used in the evaluation of nutritional conditions.

A regional approach to projecting land-use change and resulting ecological vulnerability.

This study explores ecological vulnerability to land-use change in the U.S. Mid-Atlantic Region by spatially extrapolating land and economic development, and overlaying these projections with maps of sensitive ecological resources. As individual extrapolations have a high degree of uncertainty, five methods with different theoretical bases are employed. Confidence in projections is increased for counties targeted by two or more projection methods. A county is considered at risk if it currently supports three or more sensitive resources, and is projected to experience significant growth by the year 2010 by two or more methods. Analysis designated 19 counties and two cities as at risk, highlighting within a large region the priority areas where state and regional efforts would contribute the most to integrating environmental considerations into the process of land development. The study also found that potentially severe ecological effects of future land-use change are not limited to the outskirts of major urban areas. Recreational demands on smaller communities with mountain and coastal resources are also significant, as are initiatives to promote economic development in rural areas of high ecological quality. This approach provides a comprehensive overview of potential regional development, leading to an objective prioritization of high-risk areas. The intent is to inform local planning and decision-making so that regional and cumulative ecological degradation are minimized.

Exploring the relationship between development and road traffic injuries: a case study from India.

BACKGROUND: Road traffic injuries (RTI) are a major cause of mortality and disability in the world. Only after significant losses have communities in developed nations taken necessary steps to prevent crashes and their consequences. Increase in road safety is related to increasing socio-economic development. We aim to study the trends in injury and death rates in a developing country, India, define sub-national variations, and analyse these trends in relation to economic and population growth. METHODS: Public sector data from India were used to develop a standardized database on traffic injuries and indicator of economic development. The data were analysed using linear regression models to test the a priori hypothesis of a positive relationship between net domestic product (NDP), and injury and death rates from road crashes across states. RESULTS: The absolute burden of RTI in India has been consistently rising over the past three decades. The reported rates are lower than those estimated by global health agencies and may reflect under-reporting. Population-based rates provide a better assessment of the public health burden of RTI than vehicle-based rates. There is an inverted U-shaped relationship between NDP and injury and death rates. Even with the limited data, Kuznets phenomenon is evident for within-country level comparisons. CONCLUSIONS: India and other developing countries could learn from the experience of highly motorized nations to avoid the expected rise in RTI and deaths with economic development, by currently investing in road safety and prevention measures.

[Provincial ecological footprint of China in the year of 2002].

Based on the calculation of actual yield per unit area in 2002, this paper analyzed the ecological footprint and its composition of each province in China. The results showed that there was a significant difference in the ecological footprint and its composition among different provinces, e. g., cropland changed from 0. 078 hm2 x cap(-1) in Shaanxi to 0.126 hm2 x cap(-1) in Beijing, grazing land changed from 0.020 hm2 x cap(-1) in Jiangxi to 0.372 hm2 x cap(-1) in Xizang, forestland changed from 0.020 hm2 x cap(-1) in Guizhou to 0.209 hm2 x cap(-1) in Beijing, fishery area changed from 0.001 hm2 x cap(-1) in Xizang to 0.011 hm2 x cap(-1) in Shanghai, built-up area changed from 0.013 hm2 x cap(-1) in Guizhou to 0.045 hm2 x cap(-1) in Neimenggu, and fossil energy changed from 0.251 hm2 x cap(-1) in Guangxi to 2.854 hm2 x cap(-1) in Shanxi. The eastern and southern provinces were mostly in a state of ecological deficit, while the western and northern provinces were mostly in a state of ecological remainder. As for the relationships among ecological footprint, economic development and technological progress, great difference existed in different provinces, e. g. , the ecological footprint was about 1 hm2 x cap(-1) in Fujian, Henan, Sichuan, Anhui, Yunnan, Shaanxi and Guizhou, while the GDP per capita changed from 1.35 x 10(4) yuan in Fujian to 0.3 x 10(4) yuan in Guizhou, and the ecological footprint per 1 x 10(4) yuan GDP changed from 0.74 hm2 in Fujian to 3.51 hm2 in Guizhou. Therefore, to resolve the conflicts between the shortage of natural resources and the economic development of China, emphasis should be put on the provinces with big ecological footprint per capita, low GDP per capita, and high ecological footprint per 1 x 10(4) yuan GDP. In these provinces, economic growth mode and industrial structure should be changed, dependence of economy on natural resources should be decreased, use efficiency and economic output of natural resources should be improved, and ecological, resources and economic sustainability should be realized.

Patterns of community-based prevention programs.

Prevention of dental caries is most effectively and efficiently achieved by community-based methods, whether in economically developed or developing countries. The role of the private practitioner is a dual one: to support the establishment of appropriate caries-preventive programs such as water fluoridation, salt fluoridation, supervised ingestion of fluoride tablets, and supervised programs of mouthrinsing with fluoride solutions and with such programs in place, to provide personal preventive care to that relatively small number of caries-susceptible people who will still need individual attention. The development of community-based programs is especially critical in those developing countries where the population is growing rapidly and caries is becoming more prevalent, for with their limited resources the only hope of controlling caries is with cost-effective community programs. Control of periodontal disease requires community education, but to be successful it will also require preventive care from practitioners. Even in the economically-developed countries there is a need for greater awareness of periodontal disease among both practitioners and the public. In many of these countries, now that caries is becoming better controlled, the time is ripe for considerably more prevention and treatment of periodontal disease. Its control, in the developing countries, poses special problems, and will have to depend heavily on public education for a considerable time yet. Both community-based programs and private practitioners have important roles to play in the prevention of the most prevalent oral diseases, but these roles need to be carefully defined to avoid wasteful duplication if maximum benefit is to be obtained.(ABSTRACT TRUNCATED AT 250 WORDS)

Rural system addresses social, economic needs. Cooperation, education, and advocacy revitalize a region's healthcare delivery.

In recent years leaders at Presentation Health System (PHS), Sioux Falls, SD, have expanded their mission to help strengthen local communities economically and socially. PHS now offers support to rural leaders in business, politics, and healthcare through its Center for Rural Health and Economic Development. In addition, educational outreach coordinators have created programs that address the needs of the entire rural community. To establish an effective network of services in the region, two of the system's tertiary care hospitals are collaborating to provide emergency helicopter service. These larger facilities also extend outreach services to rural hospitals and clinics. PHS assists rural hospitals in grant writing and in adapting to changing government reimbursement rules. In addition, the healthcare system coordinates a group purchasing program and a debt collection agency. An important voice for its region's healthcare needs, PHS has worked with the state of South Dakota to address problems and concerns about emergency medical services. The system also publishes Report, a quarterly newsletter that keeps rural residents abreast of healthcare issues affecting them. Two years ago, PHS's Center for Rural Health and Economic Development sponsored its first Invitational Rural Health Leadership Conference. These annual conferences bring together leaders to examine ways to improve rural healthcare delivery by strengthening the social and economic fabric of rural communities.

Human ecology and behavior and sexually transmitted bacterial infections.

The three direct determinants of the rate of spread of sexually transmitted diseases (STDs) are sexual behaviors, the mean duration of infectiousness, and the mean efficiency of sexual transmission of each STD. Underlying ecological and behavioral factors that operate through one or more of these direct determinants lie on a continuum, ranging from those most proximate back to those more remote (in time or mechanism) from the direct determinants. Most remote and least modifiable are the historical stages of economic development that even today conspicuously influence patterns of sexual behavior. Next are the distribution and changing patterns of climate, hygiene, and population density; the global population explosion and stages of the demographic transition; and ongoing changes in human physiology (e.g., menarche at younger age) and culture (e.g., later marriage). More proximate on the continuum are war, migration, and travel; and current policies for economic development and social welfare. Most recent or modifiable are technologic and commercial product development (e.g., oral contraceptives); circumcision, condom, spermicide, and contraception practices; patterns of illicit drug use that influence sexual behaviors; and the accessibility, quality, and use of STD health care. These underlying factors help explain why the curable bacterial STDs are epidemic in developing countries and why the United States is the only industrialized country that has failed to control bacterial STDs during the AIDS era.

International egg-sharing to provide donor oocytes for clinical assisted reproduction and derivation of nuclear transfer stem cells.

Recent advances in nuclear transfer technology for derivation of patient-specific stem cells have opened up new avenues of therapy for various human diseases. However, a major bottleneck is the severe shortage of human donor oocytes. Egg-sharing in return for subsidized fertility treatment has been suggested as an ethically justifiable and practical solution to ease the shortage of donor oocytes both for derivation of nuclear transfer stem cells and assisted reproduction. However, it is envisioned that many patients would be more comfortable with their supernumerary oocytes going into derivation of nuclear transfer stem cells, rather than having another potential anonymous offspring in assisted reproduction. Nevertheless in more economically developed countries, fertility treatment is easily affordable to a large segment of the population, which reduces the pool of available egg-sharers. In less affluent countries, fertility treatment is often beyond the financial resources of most sub-fertile couples. Hence, a possible solution may be to allow egg-sharing across international borders. Potential egg-sharers would come from less economically-developed countries that are more in need of financial subsidies for sub-fertile couples seeking clinically assisted conception. This is ethically justifiable because it makes fertility treatment affordable to childless couples from poorer countries, while at the same time easing the shortage of donor oocytes in more affluent countries.

[Epidemiological study on severe acute respiratory syndrome in Guangdong province].

OBJECTIVES: To understand the epidemiological characteristics of severe acute respiratory syndrome (SARS) outbreaks in some areas of Guangdong province and to provide scientific basis for prevention and control measures against it. METHODS: Standardized questionnaire was used on individual cases. Data on the epidemiological characteristics as time, place, persons and aggregation status of SARS cases, development of the epidemics, were analyzed with software EPI 6.0. RESULTS: The incidence of SARS in Guangdong province was 1.72/100,000 with case fatality rate as 3.64%. Most cases of SARS occurred between the last ten days of January and the first ten days of February with the peak (61.88% of the patients) occurred in the first ten days of February. As to the distribution of place, Pearl river delta region-economically developed with great number of mobile population-was heavily affected areas (account for 96.66% of the total patients). The majority of patients were young adults and medical staff seemed to be the most affected subgroup (account for 24.9% of the patients in total). Family and hospital aggregation of patients comprised the another two important characteristics of SARS (account for 37.1% of the total patients). CONCLUSION: Current knowledge on SARS suggested that it was an air-borne infectious disease with human beings served as the source of infection. The incubation period of the disease was from 1 to 12 days with a median of 4 days. Respiratory secretions and close contact contributed to person-to-person transmission. Most cases were distributed in Pearl river delta region, an area famous for its economic development and heavy flow of mobile population.

Is obesity replacing or adding to undernutrition? Evidence from different social classes in Brazil.

OBJECTIVE: To describe time trends in under- and overnutrition in different regional and income strata of the child and adult population of Brazil. DESIGN: Nation-wide surveys conducted in 1975, 1989 and 1996/7 in probabilistic samples of 1-4-year-old children and adults 20 years and over. Time trends refer to stunting, wasting and overweight prevalences among children and age-adjusted underweight and obesity prevalences among adults (95% confidence intervals included). SUBJECTS: Individuals examined by each survey in each age group ranged from 1796 young children in 1996 to 78031 adults in 1975. SETTING: North-eastern and south-eastern regions of Brazil. RESULTS: Undernutrition indicators declined intensively and continuously among children and adults in all region and income strata. Obesity remained low and relatively stable among children, but increased intensively and continuously in all regions and income strata among adult males. Obesity also increased intensively and continuously among adult women from the less economically developed region of Brazil (the north-eastern region) and among lower-income women from the more developed region (the south-eastern region). Higher-income women from the more developed region had a significant increase in obesity from 1975 to 1989, followed by a significant decline from 1989 to 1997. CONCLUSIONS: Undernutrition in young children is being controlled in Brazil without evidence of increasing obesity. However, obesity is rapidly replacing undernutrition in most gender, region and income strata of the adult population. Adult obesity is already more frequent than adult undernutrition in the more economically developed region, among all higher-income groups, and also among lower-income women living in the more developed region. These lower-income women are significantly more exposed than their higher-income counterparts to both undernutrition and obesity.

[Urban greenbelt eco-service value of Hangzhou City under effects of land use change: an evaluation with CITYgreen model].

Based on the Landset TM information of land use/cover change and greenbelt distribution in Hangzhou city in 1994 and 2004, and by using CITYgreen model, this paper estimated the eco-service value of urban greenbelt in the city under the effects of land use change and economic development. The results showed that in the 10 years from 1994 to 2004, the greenbelt area in the city decreased by 20. 4% , while its eco-service value increased by 168 million yuan. The annual increment of greenbelt eco-service value and GDP was 111.92% and 5. 32% , respectively. Suitable adjustment of land use pattern in the city harmonized the relationships between urban economic development and urban eco-function, and achieved higher eco-service efficiency of land utilization.

Nitrogen fertilization, soil nitrate accumulation, and policy recommendations in several agricultural regions of China.

Excessive nitrogen (N) fertilization and decreasing N recovery rates by crops have caused dramatic increases in non-point source pollution from agriculture in China. The rate of N fertilization across the country varies widely among regions and crops, depending on the stage of economic development. For example, N application rates in the eastern regions and on cash crops are far higher than in western regions of the country and on cereal crops. Moreover, N application rates in wealthier regions are higher than recommended by the Chinese Academy of Sciences. To successfully achieve environmental protection as well as high crop yields, China must formulate relevant agricultural policies to encourage farmers in economically developed areas to reduce their N fertilization rate while also issuing conventional fertilization recommendations for small-scale farming systems and the expanding cultivation of cash crops.
