We used multi-resolution satellite images to assess the long term deforestation from 2001 to 2009 and also to identify episodic forest cutting areas appeared during the conflict period of Oct. 2007 - Oct. 2008. There are only 58 ha of deforestation identified during the conflict period while 1268 ha of gross annual deforestation were assessed during last eight years. Most of the deforestation patches persist around the administrative boundaries at sub-district levels (tehsils) which can be attributed to ambiguity in unclear jurisdiction between the forest official. The results highlight that the forest cutting appeared in Swat and Shangla during the conflict period is not as significant when compared with the long term deforestation pattern in the area. On the one side the results of the study are supportive to the picture that emerges from international studies which report high rate of deforestation in the country and on the other side it negates any relation between the security situation and the increasing deforestation in the north western Pakistan. The study concludes that deforestation assessments require verification by independent sources of data, such as satellite imagery to improve our understanding of deforestation processes.展开更多

The most affected provinces were North and South Kivu where displacements of the population favor transmission of infections. Delays in diagnosis are often causes for excessive mortality among TB patients. Aim of the Study: The study aimed to test an intervention designed to increase detection of TB cases in internally displaced persons and their host communities in South Kivu province. Methods: The project used a quasi-experimental method, with prospective data collection every six months. Two peri-urban districts were selected and designated as intervention and control districts respectively. Twenty peer educators were selected among prospective TB suspects who sought care in health facilities. The peer educators were trained and encouraged to actively influence, identify and refer potential TB suspects to health centers. The data on new TB suspects seen and cases diagnosed in both districts were collected and compared over two and a half years period. Results: This pilot study has demonstrated that the intervention has had some positive effects on both the number of persons suspected with TB who were diagnosed using either microscopy or clinical assessment. Even in terms of case detection, the study demonstrated that the number of cases detected in the intervention district was at least twice the number of cases detected in the control district. Conclusion: Nonprofessional educators can influence TB case detection even in unstable settings, but their effectiveness is dependent on the security situation. National TB control programs need to adapt community mobilization strategies to local developments even in unsafe settings.展开更多
