Tsunami mortality and displacement in Aceh province, Indonesia

A survey of 388 Indonesian households displaced by the December 2004 tsunami was conducted in Aceh province in February 2005. Of tsunami-displaced households in Aceh Barat and Nagan Raya districts, 61.8 per cent reported one or more family members as dead or missing due to the tsunami, with an overall mortality rate of 13.9 per cent (95% confidence interval (CI): 12.4-15.4). Risk of death was greatest in the youngest and oldest age groups, and among females. Overall, 36 per cent of tsunami-displaced households indicated an intention to return to their original community within three months, and displaced households residing in host communities were 2.2 (95% CI: 1.2-2.8) times more likely to state an intention to return to their original villages or another community as those residing in camps. The tsunami recovery effort should focus on strategies that facilitate either prompt return or permanent, voluntary relocation for those displaced.     

Forced migration, processes of return and livelihood construction among pastoralists in northern Sudan

The Hawaweer, a nomadic, pastoralist group in northern Sudan, were seriously affected by the drought in the Sahel during the mid-1980s. Their experience illustrates the connection between internally displaced people, normal mobility, forced migration, dilemmas and opportunities of return and how new livelihoods can be successfully constructed based on traditional rights, strong local institutions and external resources. Some displaced Hawaweer got the chance to return to their homeland as new livelihood opportunities were established; others did not get this opportunity nor would they have returned if they had been given the chance. In both situations, the processes of displacement and return had an impact on the sense of belonging and identity.     

Falls and fall prevention programmes in developing countries: environmental scan for the adaptation of the Canadian Falls prevention curriculum for developing countries

Problem

Falls in older persons in developing countries are poorly understood, and falls prevention and health promotion programmes for this population are largely lacking.

Methods

A systematic review was carried out of relevant literature on falls and prevention programmes, and falls prevention education, and a scan undertaken of health promotion programmes for older persons in a representative country - South Africa.

Results

Studies on the risk and prevalence of falls are largely retrospective and hospital-based, with varied methodology, including study period, sampling method and sample size. Falls prevalence is based largely on self-reports in studies on general trauma in all age groups. Falls incidence varies from 10.1% to 54%. No reports could be traced on sustained falls prevention or health promotion programmes.

Conclusion

Scant research has been conducted and little preventive education offered on falls in older persons. Adaptation of the Canadian Falls Prevention Curriculum for developing countries will help to fill gaps in knowledge and practice.

Impact on industry

With rapid increase in the populations of older persons in developing countries, research on age related disorders such as falls is required to guide policy and management of falls.

The Accuracy of Mortality Reporting in Displaced Persons Camps During the Post-emergency Phase

For humanitarian organisations, accurate data are essential to identify emerging health problems and determine programme needs. We visited 45 post-emergency phase displaced persons camps and collected three months' mortality data which we compared with organisations' routine mortality reports. Organisations reported 612 deaths and we identified 741 deaths, for a mortality-reporting ratio, defined as the number of organisation-reported deaths divided by the number of investigator-identified deaths, of 83 per cent. For the majority of camps which under-reported deaths, mortality reporting ratios were significantly higher for women than men, and for camps with central mortality registers rather than those without. In the few camps which over-reported deaths, these occurred primarily among children younger than five years of age, probably due to the inclusion of abortions and stillbirths. Despite the overall under-reporting of deaths by humanitarian organisations, the existing health information systems appear to estimate mortality rates adequately in these post-emergency camps. However, organisations should improve the precision and completeness with which they report the characteristics of deaths in order to provide valuable data to target their programmes at the most vulnerable people.     

The future of food security in the Three Areas of Sudan

Currently, the pace of recovery in the 'Three Areas' is moving faster than the implementation of the Comprehensive Peace Agreement (CPA). This gap is leading to greater imbalances in income, unsustainable urbanization, overexploitation of the environment and resource based conflict. Unless regulated, the likely result will be chronic poverty and an undermining of the success of the CPA. Agencies must be mindful of how they provide assistance so that they support the CPA. The analysis of food security should take place in the context of a larger political, social and economic analysis of the emerging situation. The least developed areas should be prioritised and interventions should provide benefits to the full range of socioeconomic groups. WFP must identify its role in the wider and integrated response. It should support the emerging peace process and the key reforms. If WFP chooses to consolidate its activities, it will require capable strategic partners. If it chooses to invest more in building the capacity of government and community structures, it must improve its skill base and field presence     

Internal displacement in Burma

The internal displacement of populations in Burma is not a new phenomenon. Displacement is caused by numerous factors. Not all of it is due to outright violence, but much is a consequence of misguided social and economic development initiatives. Efforts to consolidate the state by assimilating populations in government-controlled areas by military authorities on the one hand, while brokering cease-fires with non-state actors on the other, has uprooted civilian populations throughout the country. Very few areas in which internally displaced persons (IDPs) are found are not facing social turmoil within a climate of impunity. Humanitarian access to IDP populations remains extremely problematic. While relatively little information has been collected, assistance has been focused on targeting accessible groups. International concern within Burma has couched the problems of displacement within general development modalities, while international attention along its borders has sought to contain displacement. With the exception of several recent initiatives, few approaches have gone beyond assistance and engaged in the prevention or protection of the displaced.     

HIV/AIDS among conflict-affected and displaced populations: dispelling myths and taking action

Conflict, displacement, food insecurity and poverty make affected populations more vulnerable to HIV transmission. However, the common assumption that this vulnerability necessarily translates into more HIV infections and consequently fuels the HIV/AIDS epidemic is not supported by data. Whether or not conflict and displacement affect HIV transmission depends upon numerous competing and interacting factors. This paper explores and explains the epidemiology of HIV/AIDS in conflict and addresses the unique characteristics that must be addressed when planning and implementing HIV/AIDS interventions among populations affected by conflict as compared with those in resource-poor settings. These include targeting at-risk groups, protection, programming strategies, coordination and integration and monitoring and evaluation. Areas for future HIV/AIDS operational research in conflict are discussed.     

西安东郊某废弃钢铁厂油松年轮记录的重金属含量变化过程

以西安市东郊某废弃钢铁厂为例,采用石墨炉原子吸收法、电感耦合等离子体原子发射光谱法、原子荧光法测定了废弃钢铁厂两棵油松(Pinus tabulaeformis Carr.)树盘及其根部土壤中重金属Cr、Mn、Hg、Zn、Pb、Cd和类金属As以及P等8种元素的含量.土壤测定结果表明,该地区Cr、Zn、As等元素含量超过了西安市郊区土壤背景值,Cr、Mn等元素易在深层土壤中积累,Hg、Zn等元素不易在深层土壤中积累.两个树盘年轮中这8种元素的含量随着年代的推移总体呈现上升的趋势,这表明该地区由这些元素引起的污染状况日益加重.Hg、Pb、Cd等元素于1996年左右吸收达到最高峰,与该钢铁厂生产历史相一致.这两个树盘中Mn、Hg、Zn、As、P等元素自1993年后均呈现比较一致的增长趋势.通过计算各元素的自相关系数,从统计学角度发现这8种元素在油松年轮中的迁移特征:Mn、Zn、As等元素均存在着3年的横向迁移趋势,Pb、P存在2年的迁移趋势,Hg、Cd有1年的迁移,而Cr几乎不迁移,其中Zn、Cd、P等元素在油松中的迁移趋势与西安市西部某地区椿树和桐树中的迁移趋势表现一致.
