The importance of livestock as a pathway out of poverty is widely recognised, but the effectiveness of pro-poor livestock development projects has been questioned. This study examines a sample of livestock development projects to draw lessons about their effectiveness and identify best practice. A large proportion of projects (60 per cent) were categorised as having not been successful. Project success is found to be positively associated with size of project, diversity of direct project beneficiaries, institution development activities in projects, and effective monitoring and evaluation activities. Lack of reliability of government partners, and inclusion of other agricultural activities together with livestock activities in projects, undermine success.

Résultats en matière de développement pro-pauvres des projets basés sur l’élevage : analyse et enseignements tirés de la documentation de projets

L'importance de l’élevage comme moyen d’échapper à la pauvreté est largement reconnu, mais l'efficacité des projets de développement pro-pauvres basés sur l’élevage a été mise en cause. Cette étude examine un échantillon de projets de développement basés sur l’élevage pour en tirer des enseignements concernant leur efficacité et identifier les meilleures pratiques. Un considérable pourcentage des projets (60 pour cent) ont été catégorisés comme n'ayant pas réussi. Le succès des projets se révèle être positivement associé à la taille du projet, à la diversité des bénéficiaires directs du projet, aux activités de développement des institutions dans le cadre des projets, et à des activités efficaces de suivi et d’évaluation. Le manque de fiabilité des partenaires gouvernementaux et l'inclusion d'autres activités agricoles dans les activités d’élevage dans le cadre des projets ont aussi une incidence négative sur le succès.

Desempeño de los proyectos de desarrollo ganadero en pro de los pobres: análisis y aprendizajes a partir de la documentación de los proyectos

Es ampliamente reconocida la importancia que tiene el ganado como un medio para salir de la pobreza. Sin embargo, se ha cuestionado la efectividad de algunos proyectos de desarrollo ganadero en pro de los pobres. El presente estudio examina una muestra de proyectos de desarrollo ganadero, con el fin de obtener aprendizajes sobre su efectividad y de identificar las mejores prácticas. Un elevado porcentaje (60%) de los proyectos fue clasificado como no exitoso. Se encontró que el éxito del proyecto se asocia positivamente a su tamaño, a la diversidad de los beneficiarios directos, a las actividades de desarrollo llevadas a cabo por las instituciones participantes en el proyecto, así como a actividades de monitoreo y de evaluación efectivas. El éxito de los proyectos se ve disminuido por la falta de formalidad de las contrapartes gubernamentales y por la incorporación de otras actividades agrícolas en los proyectos ganaderos.

Desempenho de projetos sobre gado pra o desenvolvimento dos pobres: análise e lições extraídas da documentação de projetos

A importância da criação de gado como um caminho para sair da pobreza é altamente reconhecida, mas a efetividade de projetos sobre a criação de gado para o desenvolvimento de pessoas pobres tem sido questionada. Este estudo examina uma amostra de projetos sobre criação de gado para o desenvolvimento visando extrair lições sobre sua efetividade e identificar as melhores práticas. Uma grande proporção dos projetos (60 por cento) foi classificada como não tendo sido bem-sucedida. Constatou-se que o sucesso do projeto está positivamente associado ao seu tamanho, diversidade dos seus beneficiários diretos, atividades de desenvolvimento institucional nos projetos e monitoramento efetivo e atividades de avaliação. A falta de confiança de parceiros do governo e a inclusão de outras atividades agrícolas, juntamente com as atividades de criação de gado nos projetos, impossibilitam o seu sucesso.  相似文献

The wave of democratization in the 1990s has brought considerable challenges and opportunities for post‐cold war Africa. One such challenge is the democratic intervention of the Economic Community of West African States (ECOWAS) under the aegis of the multilateral intervention force, ECOMOG, to restore a democratic government and constitutional order. The ECOWAS democratic intervention in the West African state of Sierra Leone can be located in a wider debate about international dimensions of democratization. In several respects, it also reflects the changing nature of international politics in the post‐cold war period particularly with regards to certain traditional norms of international society, namely non‐intervention and state sovereignty. The ECOWAS democratic efforts in Sierra Leone demonstrate that it is increasingly becoming acceptable for regional and international organisations to ‘defend’ democracy, albeit under the auspices of forcible as well as non‐forcible humanitarian intervention. However, these kinds of external intervention on behalf of democracy have in most cases led to its retrenchment. This article therefore critically assesses how the nature of domestic politics led to the suspension of democracy in Sierra Leone, the domestic and international implications of the ECOWAS defence of democracy there and the country's post‐conflict democratic prospects.  相似文献

Over the past decade small arms and light weapons availability has been singled out as one of sub-Saharan Africa's highest profile challenges. Yet the construction of the threat of arms availability as one of authorised trade and illicit trafficking across international borders has resulted in a narrow focus on regulating lawful exports and imports and brokers. While these are real and legitimate concerns, the authors contend that small arms and light weapons availability should be re-evaluated as a complex social phenomenon involving dynamic supply and demand dimensions. A limited emphasis on controlling authorised transfers to war zones glosses over the challenges of illegal markets, the gradual emergence of national arms production capacities across Africa and the systematic diversion of weapons and ammunition surplus from the domestic stocks of security services into civilian hands. It also obscures a more dynamic landscape of armed violence across the continent which extends beyond war zones. Whilst the conventional interpretation of arms availability is favoured by African diplomats and international arms control experts, such a reading potentially obscures the weaknesses of security governance and the myriad motivations and means shaping small arms and light weapons acquisition and misuse amongst armed groups and civilians.  相似文献

The article concentrates on the several legal issues that have come up in piracy trials before the Supreme Court in relation to jurisdiction, human rights, joint and secondary party liability, attempts, mens rea, presumption of piracy from those found cruising the high seas with weapons and sentencing. The article also deals with factual issues in relation to determining; the identity, age, nationality of accused and time of attack due to different time zones, placing reliance on GPS, video, photographic and hearsay evidence and use of system evidence from the common pattern followed by a typical piracy action group.  相似文献

In Seychelles, the mens rea of murder can be established, as an alternative to an intention to cause death or grievous harm, on the basis of the defendant’s ‘knowledge’ that the act or omission causing death will probably cause death or grievous harm. However, a defendant is only allowed to plead intoxication as a defence where it had become impossible for him to form the necessary ‘intention’ due to intoxication. This article highlights the difficulties in the application of the defence of intoxication to cases where the mens rea for murder is based purely on a defendant’s ‘knowledge’. In analysing the defence of intoxication in Seychelles in cases of murder, the article examines the position under English and Australian law.  相似文献

As early as the 1970's, privacy studies recognised that ‘anonymisation’ needed to be approached with caution. This caution has since been vindicated by the increasing sophistication of techniques for reidentification. Yet the courts in the UK have so far only hesitatingly grappled with the issues involved, while European courts have produced no guidance.  相似文献

From time to time the Court of Appeal feels the need to steer inferior courts and tribunals away from an over-enthusiastic application of a particular direction of travel signposted by its own previous decisions. In the Edem judgment, published on 7 February 2014, the court has taken the opportunity to restrict significantly the application of its decision more than a decade ago in Durant v. Financial Services Authority, 1 a case that has been relied on by many commercial data protection practitioners to deny subject access or the wider application of the Data Protection Act 1998 on the grounds that the data were not personal in that they did not relate to the individual in question even though the individual's name appeared as part of the data.  相似文献

Aortic aneurysm refers to the pathological dilatation of the normal aortic lumen involving one or several segments. Thoracic aortic aneurysms are much less common than aneurysms of the abdominal aorta. Descending thoracic aortic aneurysm leading to dissection and spontaneous rupture is a potentially catastrophic illness. Although rare, dissection and rupture of a preexisting aortic aneurysm have been reported during pregnancy and early puerperium. To the best of our knowledge, such cases among young pregnant women are rarely reported in literature. Herein, an autopsy case of spontaneous rupture of a clinically undiagnosed descending thoracic aortic aneurysm during early puerperium in a young woman is presented along with the review of relevant literature. The victim was found dead on her hospital bed on the seventh day of puerperium. Autopsy with ancillary investigations revealed that the young woman died because of hemothorax from a ruptured dissecting descending thoracic aortic aneurysm secondary to chronic aortitis.  相似文献
