Integrated environmental impact assessment: a Canadian example.

The Canadian federal process for environmental impact assessment (EIA) integrates health, social, and environmental aspects into either a screening, comprehensive study, or a review by a public panel, depending on the expected severity of potential adverse environmental effects. In this example, a Public Review Panel considered a proposed diamond mining project in Canada's northern territories, where 50% of the population are Aboriginals. The Panel specifically instructed the project proposer to determine how to incorporate traditional knowledge into the gathering of baseline information, preparing impact prediction, and planning mitigation and monitoring. Traditional knowledge is defined as the knowledge, innovations and practices of indigenous and/or local communities developed from experience gained over the centuries and adapted to local culture and environment. The mining company was asked to consider in its EIA: health, demographics, social and cultural patterns; services and infrastructure; local, regional and territorial economy; land and resource use; employment, education and training; government; and other matters. Cooperative efforts between government, industry and the community led to a project that coordinated the concerns of all interested stakeholders and the needs of present and future generations, thereby meeting the goals of sustainable development. The mitigation measures that were implemented take into account: income and social status, social support networks, education, employment and working conditions, physical environments, personal health practices and coping skills, and health services.

[Problems in development of agriculture-animal husbandry ecotone and its countermeasures].

Problems in development of Duolun, a typical agriculture-animal husbandry ecotone, and its countermeasures were discussed in this paper. Economic structure was not rational in Duolun, and it should develop industry and commerce, limit the scope of agriculture and animal husbandry, and actively increase efficiency of agriculture and animal husbandry. The structure of land use was not rational, and the main countermeasures were to increase area of forestland and grassland, and decrease cultivated area. On resources use, the main countermeasures were to exploit water resource rationally and bring into play resource superiority of mutually benefits on agriculture and animal husbandry. The ecological environment construction was the foundation of the national economy for sustainable development in agriculture-animal husbandry ecotone.

Ecotourism and community development: case studies from Hainan, China.

The connections between people, parks, and tourism have received significant attention in recent years, recognizing the potential for mutually beneficial relationships. Ecotourism has been promoted and widely adopted as a strategy for funding conservation initiatives, while at the same time contributing to the socioeconomic development of host communities and providing for quality tourism experiences. Parks are among the most common ecotourism destinations. Employing interviews, observations and secondary sources, this study assesses the current status of ecotourism at two protected areas in Hainan, China, where it is being promoted as a strategy for balancing regional economic growth and conservation objectives. Through an evaluation of the existing tourism-park-community relationships, opportunities and constraints are identified. Ecotourism development was found to be at an early stage at both study sites. Socioeconomic benefits for the local communities have been limited and tourism activity has not contributed revenues towards conservation to date. Community residents, nevertheless, generally support conservation and are optimistic that tourism growth will yield benefits. In light of the study findings and the salient literature, planning direction is offered with the intention of enhancing the capacity of ecotourism to generate benefits for both communities and the parks, and thus contribute to the sustainable development of the region more generally. Lessons derived have broad applicability for ecotourism destinations elsewhere.

Protecting the patient and the environment--new aspects and challenges in hospital infection control.

Environmental pollution has become a major concern for the future of life on our planet; medical care, especially in hospitals, contributes significantly to this pollution. The increasing usage of highly-developed medical devices, drugs and disposable products are a drain on natural resources as well as financial ones. In this situation, it is a major task for hospital epidemiologists to maintain high standards of hygiene while reducing environmental pollution, reducing consumption of limited natural resources, and minimizing costs. The reduction of hospital waste, the control of polluting and toxic emissions, the avoidance of unnecessary disinfection procedures and disposables, the implementation of energy and water saving technologies are practicable measures in hospital ecology. To realize a sustainable development within hospitals, it is necessary that the need to maintain a balance between effective infection control and a good ecological environment is recognized and supported by health-care workers and the hospital management.

[Research on the relationship between water and eco-environment construction in Loess Hilly and Gully regions].

Water is an important factor for eco-environmental construction. Eco-environmental construction has a great impact on water. There is a circular correlation between eco-environmental construction and water. Water resource is lack and loss of soil and water is serious in the loess hilly and gully regions. The regions are the main regions of eco-environmental construction, especially of vegetation restoration and rehabilitation. It is important studying the relationship between water and eco-environmental construction in the regions. According to the data in Yanhe River watershed, some conclusion are demonstrated: 1. More water resource was demanded when population was increasing rapidly and economy was developing fleetly. Water for eco-environmental construction was threatened directly. 2. Eco-environmental construction, especially the built vegetation decreased the runoff. The dried soil layers have appeared in some places. 3. Shortage of water resource limited the farther tree and grass planting and brought on some negative impacts. Small aged trees have appeared in some places. The eco-environmental benefits of the built vegetation have been influenced. On the basis of relationship between water and eco-environmental construction, some advice for sustainable use of water resource, sustainable construction of eco-environment and sustainable development of society and economy was given.

The injury iceberg: an ecological approach to planning sustainable community safety interventions.

ISSUE ADDRESSED: A systematic ecological framework in which to design sustainable, community-based, safety promotion interventions is presented. METHOD: A literature review was undertaken of English-language articles addressing the topics of 'ecological injury prevention or safety promotion', 'ecological health promotion', 'sustainable economic, health or ecological systems' and 'steady state', with 143 articles retrieved and reviewed. RESULTS: Injury prevention is a biomedical construct, in which injury is perceived to be a physical event resulting from the sudden release of environmental energy producing tissue damage in an individual. This reductionist perspective overlooks the importance of psychological and sociological determinants of injury. Safety has physical, psychological and sociological dimensions. It is inherently an ecological concept. Interventions aiming to achieve long-term improvements in community safety must seek to develop sustainable safety promoting characteristics within the target community. CONCLUSION: To reduce a community's risk of injury and sustain this lowered risk, the community 'ecological system' must have access to the resources necessary to maintain the desired outcome and the ability to mobilise these resources.

Sustained decreases in platelet count associated with multiple, regular plateletpheresis donations.

BACKGROUND: Transient but significant decreases in platelet counts have been documented to occur in donors undergoing single and serial short-term plateletpheresis collections. The effect of long-term regular plateletpheresis on donor platelet counts has not been characterized. STUDY DESIGN AND METHODS: A retrospective study was performed to evaluate the effects of long-term regular plateletpheresis donation on donor platelet counts. A computerized database containing records of 11,464 apheresis collections from 939 donors over a 4-year period was queried for serial preapheresis platelet counts. Donors were categorized by sex, age, and cumulative number of donations. The average difference in platelet counts (mDeltaPC) between each donor's first and last platelet count during this period was calculated for each category. A subgroup of frequent donors was selected for analysis of mDeltaPC, using the baseline platelet count obtained before the first plateletpheresis procedure. RESULTS: A significant and sustained decrease in platelet count was identified for all donation frequency categories. The frequency of donation correlated directly with decrease in platelet count for all but the highest-frequency donation group, in which deferrals for low platelet count blunted the extent of the mDeltaPC. A mean decrease of 40,000 per microL from baseline occurred in the frequent-donor subgroup. A total of 84 donors (9%) were deferred for low platelet count. The majority returned to donate successfully after temporary deferral. CONCLUSIONS: Regular plateletpheresis donors develop sustained decreases in platelet count. However, clinically significant thrombocytopenia is unusual when rigorous ongoing review and prudent deferral policies are established and followed.

Factors affecting participating farmers' willingness-to-pay for the Tree Farming Fund: a study in a participatory forest in Bangladesh.

This paper examined the factors that might influence participating farmers' willingness-to-pay for the Tree Farming Fund (TFF) established for sustainable development of participatory forest management (PFM). Information on willingness-to-pay, socioeconomic characteristics, and attitudes of participating farmers toward TFF were obtained from interviews with 581 participating farmers. Logistic regression analysis was used to determine the dominant factors that might influence participating farmers' willingness-to-pay for the TFF. The results showed that participating farmers' willingness-to-pay was significantly affected by (i) family income; (ii) education level; (iii) confidence that his aspired benefits will be received; (iv) agreement with the statement that 'PFM is sustainable under the present state of management'; (v) agreement with the statement that 'PFM is a good strategy for forest conservation'; and (vi) knowledge of PFM strategies. Thus, participating farmers with a higher level of education, higher income and positive attitudes toward TFF tended to express more willingness-to-pay. Establishment of TFF could be an effective strategy in implementing sustainable PFM in Bangladesh. For this strategy to succeed, however, active partnership between the participating farmers and Forest Department is required. Participating farmers' attitudes toward TFF should therefore be taken into consideration as should the results of this study, which are important indicators of participating farmers' positive attitudes toward TFF.

Maternal health services--the developing world.

Women in developing nations run 100 to 200 times the risk of dying in pregnancy and childbirth compared to women in affluent countries. The vast majority of these deaths are preventable. We examine 3 models of health development for their potential impact on maternal mortality. Although universal primary maternal health care would be ideal, resource limitations render its implementation impractical in many regions. The nonavailability of transport and referral services limits the impact of community-based programs. Selective primary health interventions have some role, but more costly and complex services are required to deal with hemorrhage, the complications of illegal abortion and to provide operative deliveries. Public health workers should focus on intersectoral programs at the community level which mobilize women around health issues. Sustainable development has the greatest potential to produce lasting changes in the risks of childbearing.

We must tackle population problems.

Thank you Mr. Chairman, for the opportunity to speak out not only as a Japanese parliamentarian, but also as a member of GLOBE International, Global Legislators Organization for a Balanced Environment, consisting of legislators from the US Congress, EC Parliament, USSR Assembly and Japanese Diet who have joined together to compare, improve and coordinate our respective legislative activities in an effort to effectively address the complex issues surrounding environment and development. Mr. Chairman, world population--which reached 5.4 billion in mid-1991--is growing exponentially. According to 1 UNFPA report 3 people are born every second, a total of 250,000 people every day or 95-100 million people every year. At this rate, world population will reach 6.4 billion by year 2001, and if this rate continues to go unchecked, world population will reach 14-15 billion by the end of the 21st century. GLOBE is highly aware of the relationship between rapidly growing human populations, environmental degradation and sustainable development. We urge UNCED negotiators to address population growth rates and the integrally linked concerns of resource consumption levels, particularly in the industrialized world, in their search for solutions to the conflict between environment and development. Negotiators should also seriously consider ways in which to broaden educational and economic opportunities for women to ease population growth rates, and to alleviate poverty and stresses on the environment that result from population pressures. Social and economic factors must be integrated into population planning. It is saddening to note that almost 40,000 children die every day due to malnutrition, lack of fresh water and access to resources. Over 100 million children do not receive a primary education. Mr. Chairman, worldwide demand for a range of family planning services is increasing faster than supply. Recent studies indicate that if quality family planning information, training and services were made readily available by government and other groups, population rates would drop to manageable levels. Widespread access to family planning services is essential to population stabilization. The health of mothers, children and general quality of life is also improved through the implementation of family planning programs. At the present time many women cannot make use of the limited available services because of cultural constraints, lack of status and self-confidence. Unless complementary efforts are made to expand economic and educational opportunities for women, family planning and other reproductive health services will not reach their full potential for stabilizing population. Although family planning is an individual decision, and implementation of population programs is a sovereign matter in each country, I would urge developed countries to help their neighbors in developing countries who are in need of support for family planning and health services. Investment in family planning programs is 1 of the best ways to contribute to environmental protection and improvement. A greater portion of our foreign aid monies should be allocated for direct population assistance programs that will reach people at the grassroots level. To achieve this, a cooperative working relationship with local nongovernmental organization (NGOs) is essential. The members of GLOBE hope to facilitate cooperation between NGOs and governments so that we might stabilize human population.

Endothelin-1 does not mediate the endothelium-dependent hypoxic contractions of small pulmonary arteries in rats.

Various pulmonary artery preparations in vitro demonstrate sustained endothelium-dependent contractions upon hypoxia. To determine whether endothelin-1 could mediate this phenomenon, we examined the effect of bosentan, a new antagonist of both the ETA and ETB subtypes of the endothelin receptor. Small (300 pm) pulmonary arteries from rats were mounted on a myograph, precontracted with prostaglandin F2 alpha and exposed to hypoxia (PO2, 10 to 15 mm Hg, measured on-line) for 45 min. Endothelium-intact control rings exhibited a biphasic response, with a transient initial vasoconstriction (phase 1) followed by a second slowly developing sustained contraction (phase 2). Expressed in percent of the maximal response to 80 mmol/L KCl, the amplitudes of phase 1 (peak tension) and 2 (tension after 45 min of hypoxia) averaged 37 +/- 12% and 17 +/- 14%, respectively (n = 11). In endothelium-denuded rings, phase 1 persisted while the amplitude of phase 2 was reduced to 2 +/- 12% (p < 0.05, n = 8), showing the endothelium dependence of this contraction. Neither phase was significantly decreased in rings treated with 10(-5) mmol/L bosentan (38 +/- 15% and 17 +/- 12%, respectively, n = 6). The PO2 threshold for onset of hypoxic contraction was not significantly different among these three groups and averaged 32 +/- 24 mm Hg. In a separate experiment, we assessed the inhibitory effect of 10(-5) mol/L bosentan on the response to 10(-8) mol/L endothelin-I. Rings treated for 45 min with 10(-8) mol/L endothelin-1 alone exhibited a maximal contraction of 75 +/- 27% (n = 6). This was reduced to 4 +/- 17% (p < 0.01, n = 6) in rings treated with both 10(-8) mol/L endothelin-1 and 10(-5) mol/L bosentan. We conclude that complete blockade of all endothelin receptor subtypes has no effect on either endothelium-dependent or -independent hypoxic contractions in this preparation. This suggests that endothelial factors other than endothelin-I mediate the acute hypoxic contractions of small pulmonary arteries in the rat.

Advances in Cytoplasmic Male Sterility in Sugar Beet from Mitochondrial Genome Structural Dynamics and Nuclear-Cytoplasmic Coordination.

Sugar beet (Beta vulgaris L.) is a globally important sugar crop whose hybrid breeding system relies heavily on cytoplasmic male sterility (CMS) lines. Recent advances in sugar beet genomics, particularly the release of high-quality reference genomes and the characterization of organellar genomes, have provided a foundation for elucidating the molecular genetic mechanisms of CMS. Furthermore, innovations in gene editing technologies are enabling transformative functional studies in this field. The precise targeting of CMS-associated mitochondrial genes and nuclear restorer-of-fertility genes not only allows for direct investigation of theoretical models governing fertility regulation through nuclear-cytoplasmic interactions but also holds promise for the targeted development of sterile and restorer lines. This review systematically summarizes progresses in sugar beet genomics, the development of gene editing tools, and the current understanding of the molecular genetics of CMS and fertility restoration in sugar beet. Although challenges remain-such as efficient delivery of editing tools into mitochondria and coordinated editing of multiple genes-the integration of genomic and gene editing technologies is expected to accelerate multi-omics-guided dissection of CMS mechanisms. These advances will facilitate the precise design of high-yield, high-sugar, and stress-resistant sugar beet hybrids, thereby providing core scientific and technological support for the sustainable development of the global sugar industry.

The temporal integration of the aldosterone secretory response to angiotensin occurs via two intracellular pathways.

Angiotensin II (AII) regulates the secretion of aldosterone from adrenal glomerulosa cells by a calcium-dependent mechanism which involves both the uptake of calcium from the extracellular pool, and the release of calcium from a dantrolene-sensitive intracellular pool. In the present study, it was shown that AII induces the rapid (10 s) hydrolysis of phosphatidylinositol 4-phosphate and -4,5-bisphosphate, leading to the sustained production of inositol bis- and trisphosphate (Ins-P3), and diacylglycerol rich in arachidonic acid. Saponin-permeabilized glomerulosa cells accumulate calcium into a nonmitochondrial pool by an ATP-dependent manner. Ins-P3 (0.5-5 microM) induces a release of Ca2+ from this pool. This release was blocked by dantrolene (10 microM). Adrenal glomerulosa cells were shown to contain the calcium-activated, phospholipid-dependent protein kinase (C-kinase). Perfusion of glomerulosa cells with combined 12-O-tetradecanoyl phorbol 13-acetate and A23187 induced an immediately developing, sustained, maximal secretory response similar to that induced by AII. These data are interpreted in terms of a model in which, after AII addition, there is a flow of information through two separate branches of the calcium messenger system, each with its unique temporal role: a calmodulin branch activated by the transient rise in the [Ca2+] in the cell cytosol, which is largely responsible for the initial transient cellular response; and a C-kinase branch activated by the increase in both cytosolic [Ca2+] and the diacylglycerol content of the plasma membrane, which is largely responsible for the sustained phase of the cellular response. The temporal integration of these two phases underlies the observed pattern of cellular response.

Coming to terms with Vietnam: the Viet/American Cervical Cancer Prevention Project.

The Viet/American Cervical Cancer Prevention Project embraces a dual mission. We seek to develop sustainable, cost-effective cervical cancer prevention services for women in Vietnam. Because the problem of cervical cancer in Vietnam is in part a legacy of the Second Indochinese War, we also seek to examine obstacles to reconciliation by presenting what most acknowledge to be a remedy in advance of what some will perceive to be an accusation. Certain research and commercial interests have produced obstacles to our dual mission in Vietnam. The Alliance for Cervical Cancer Prevention, supported by the Bill and Melinda Gates Foundation, has failed to endorse Pap screening for developing countries and is conducting clinical trials which may further disaffect medically underserved groups. Visual screening techniques combined with immediate ablative treatment methods are incompatible with the requirements of "first do no harm." Because the Pap smear will probably be a component of any future human papillomavirus (HPV)-based or visual- based screening programs, it serves the interests of those promoting noncytologic screening methods to also support the development of Pap screening services. Research on HPV screening in developing countries raises concerns of commercial exploitation. Because Pap screening is feasible wherever cervical screening is appropriate, it is inappropriate to delay the development of Pap screening services pending research into HPV vaccines or alternative screening technologies. Quality management is the point at which public health and diagnostic pathology intersect and will remain an indispensable element of cervical screening programs irrespective of the screening test(s) eventually used. Pap screening in developing countries is an ethical imperative without a substantial political constituency and will benefit from the engagement of organized cytology.

Discovery Path: a retention strategy for mid-career nurses.

As health care administrators, policymakers, nursing organizations, and nurses begin to deal with the reality of a looming (and to an increasing extent, existing) serious shortage of nurses both in Canada and globally, recruitment and retention issues are again in the news. Much attention has been directed towards two responses: (a) attracting young people into the profession and helping them integrate into and identify with nursing as a lifelong career, and (b) developing sustainable retention strategies to ensure that nurses remain in nursing. One population that requires particular attention is the mid-career group of nurses. Those nurses, in their late 30s and 40s with 15 and more years of experience, have the professional memory that employers count on, the expertise that patients and clients require, and the experience and wisdom that young nurses depend on for coaching, mentoring, and support. Retention strategies targeted to these mid-career nurses require a diverse set of activities that are focused on those nurses' specific stage of personal and professional development and that recognize their unique needs. The purpose of this article is to describe a program that targets mid-career nurses, predominantly women who, having spent much of their careers and lives caring for others-children, parents, patients-are beginning to question their own futures. The goals of the program and the experiences of one group of nurses in the program, as well as the results of a two-year follow up with them, will be discussed. Recommendations for future retention strategies will also be offered.

[Environmental cost of rice production in Dongting Lake area of Hunan Province].

To evaluate the environmental cost of rice production is of significance for the sustainable development of agriculture and the set-up of green GDP accounting system. In this paper, the environmental cost of rice production in Dongting Lake area, one of the main bread baskets in China, was evaluated from the aspects of pesticide pollution, chemical fertilizer pollution, greenhouse gases emission, plastic film persistence, paddyfield gleyization, and polderization. The results showed that in 1999, the total environmental cost of rice production in this area was 41.91 billion yuan, equivalent to 26.8% of its total agricultural production value, or 28.5% of the gross output of its planting industry. For the sustainable production of rice, the strategies for decrease environmental cost intrinsically were put forward.

Effects of glucose on hypoxic vasoconstriction in isolated ferret lungs.

To characterize the effects of glucose on the pulmonary vascular response to anoxia and hypoxia, isolated ferret lungs were ventilated with 28% O2 and 5% CO2 and perfused at constant flow (100 ml.kg-1.min-1). Perfusate glucose concentrations were allowed to fall spontaneously to less than 1 mM (low glucose) or were controlled at 5-6 mM (normal glucose) or 12-17 mM (high glucose). At 60, 120, and 180 min of perfusion, the inspired O2 tension (PIO2) was reduced to 0, 10, or 30 Torr for 30 min, and vasomotor responses were quantified by continuous measurement of pulmonary arterial pressure. At PIO2 of 0 Torr, the response consisted of an early phase of transient intense vasoconstriction and a late phase of sustained slight vasoconstriction. High glucose markedly potentiated the magnitude of late-phase vasoconstriction with each successive anoxic exposure. This effect was not reproduced in normal glucose lungs and was not caused by a change in perfusate osmolarity, an action on blood cells, or an altered ability of pulmonary vascular smooth muscle to contract. At PIO2 of 10 Torr, high glucose not only potentiated late-phase vasoconstriction but also slowed the onset of early-phase vasoconstriction. At PIO2 of 30 Torr, high glucose had no effect on vasomotor responses, which were characterized by a slowly developing sustained vasoconstriction. Our results suggest that the vascular response of isolated ferret lungs to severe hypoxia consisted of separate early and late phases of vasoconstriction. This biphasic response may have resulted from two distinct vasoconstrictor mechanisms or from modulation of a single vasoconstrictor mechanism by a secondary vasodilator influence.(ABSTRACT TRUNCATED AT 250 WORDS)

From concept to practice: including the social determinants of health in environmental assessments.

The present paper examines the historical evolution of health impact assessments as part of the environmental assessment process. The development of a coherent public health framework must be based on the model of determinants of health, integrating toxic and infectious risks and social impacts of projects. The integration of common concepts, processes and methodologies from the area of public health and social impact assessment challenges the quantitative model approach to risk assessment. The expert-driven risk assessment is transformed into a social learning process where local knowledge and scientific input foster a dialogue among stakeholders. The issue-oriented, iterative and participative assessment process may be applied to the health impact assessment of public policies. Sustainable development with its social objectives of empowerment, participation, equity, poverty alleviation, social cohesion, population stability and institutional development is an appropriate framework for conducting health impact assessments.
