Double Decades of Existence of the Kilum-Ijim Community Forest in Cameroon: What Conservation Lessons?

Abstract

Abstract

At a time when natural forests remain a substantial framework for solving manifold human-induced environmental problems, forest conservation efforts have often been met with a number of challenges, especially in the midst of growing populations of forest-adjacent communities in the developing countries of the world. However, the initiation of the Kilum-Ijim Forest Project in the Western Highland region of Cameroon (erroneously considered to have been a naturally savannized environment) twenty years ago tells a success conservation story. This study, therefore, examines the fate of the Kilum-Ijim Forest prior to the forest conservation project, the conservation efforts put in place to protect and restore the biodiversity of the area, the conservation challenges, and also proposes other areas of intervention for a continuous successful conservation legacy. Due to the constant population pressure and the resultant overexploitation of the Kilum Mountain forest, the original forest size, estimated at 17,500 hectares in 1963, was reduced to 10,500 hectares by 1983. In recognition of the umbilical link between forest and forest-adjacent communities, the Cameroon Government and BirdLife International liaised with the adjacent tribal communities for a sustainable way of managing the forest. While these communities benefit through the non-consumptive use of the forest and other alternative livelihood means, the ecological viabilities of the forest are equally promoted through biodiversity restoration. Due to this community-based management approach, the Kilum-Ijim forest remains an outstanding example of a richly endowed highland montane forest, with a number of endemic wildlife species. Today, conservation efforts have restored the forest size to over 20,000 hectares. Having understood the need for forest conservation and the ensuing conservation benefits, perhaps it is time to increase the forest conservation sites while more alternatives serving human needs are designed and promoted. This conservation legacy should also serve as an example worth emulating in other highland regions with a history of forest degradation.     

Metal objects mapping after small charge explosions. A study on AISI 304Cu steel with two different grain sizes

Evidence of exposure of a metal component to a small charge explosion can be detected by observing microstructural modifications; they may be present even if the piece does not show noticeable overall plastic deformations. Particularly, if an austenitic stainless steel (or another metal having a face-centered cubic structure and a low stacking fault energy) is exposed to an explosive shock wave, high-speed deformation induces primarily mechanical twinning, whereas, in nonexplosive events, a lower velocity plastic deformation first induces slip. The occurrence of mechanical twins can be detected even if the surface is damaged or oxidized in successive events. In the present research, optical metallography (OM) and scanning electron microscopy (SEM), and scanning tunneling microscopy (STM) were used to detect microstructural modifications caused on AISI 304Cu steel disks by small-charge explosions. Spherical charges of 54.5 or 109 g TNT equivalent mass were used at explosive-to-target distances from 6.5 to 81.5 cm, achieving peak pressures from 160 to 0.5 MPa. Explosions induced limited or no macro-deformation. Two alloy grain sizes were tested. Surface OM and SEM evidenced partial surface melting, zones with recrystallization phenomena, and intense mechanical twinning, which was also detected by STM and X-ray diffraction. In the samples' interior, only twins were seen, up to some distance from the explosion impinged surface and again, at the shortest charge-to-sample distances, in a thin layer around the reflecting surface. For forensic science locating purposes after explosions, the maximum charge-to-target distance at which the phenomena disappear was singled out for each charge or grain size and related to the critical resolved shear stress for twinning.     

In the Interests of Clients or Commerce? Legal Aid,Supply, Demand,and ‘Ethical Indeterminacy’ in Criminal Defence Work

As a professional, a lawyer's first duty is to serve the client's best interests, before simple monetary gain. In criminal defence work, this duty has been questioned in the debate about the causes of growth in legal aid spending: is it driven by lawyers (suppliers) inducing unnecessary demand for their services or are they merely responding to increased demand? Research reported here found clear evidence of a change in the handling of cases in response to new payment structures, though in ways unexpected by the policy's proponents. The paper develops the concept of ‘ethical indeterminacy’ as a way of understanding how defence lawyers seek to reconcile the interests of commerce and clients. Ethical indeterminacy suggests that where different courses of action could each be said to benefit the client, the lawyer will tend to advise the client to decide in the lawyer's own interests. Ethical indeterminacy is mediated by a range of competing conceptions of ‘quality’ and ‘need’. The paper goes on to question the very distinction between ‘supply’ and ‘demand’ in the provision of legal services.     

Incentives, criminal defence lawyers and plea bargaining

Plea bargaining has become a central feature of criminal procedure in Anglo-Saxon jurisdictions. This paper explores an area seldom discussed in the economic literature on plea bargaining: the influence of the defence lawyer's fee contract on the terms of the bargain. In particular, it uses data from one jurisdiction of the impact on case trajectories of changes in publicly funded defence lawyers’ contracts to test the proposition that the nature of the lawyer's contract influences how cases are managed. An event study methodology on a pooled time-series cross-section data set of case trajectories before and after the change in the nature of the contract is used to examine whether the new payment regime significantly changed the trajectories of cases through the summary criminal justice system. Overall the results seem to suggest that the behaviour of defence lawyers may be influenced by financial incentives. This implies that the terms of plea bargains reached between prosecution and defence lawyers may be affected by the defence lawyer's remuneration contract. Consequently, the authors conclude that the role of defence lawyers has been under-researched in the literature on the economics of plea bargaining.     

'Ritual Individualization': Creative Genius at Sentencing,Mitigation, and Conviction

Judges and lawyers must regard themselves as upholding cherished values, including the presumption of innocence; free defendant choice and participation; and attention to the unique individual. Yet, everyday criminal work also demands compliance with a system of perfunctory, mass case disposal. How is this potential contradiction addressed? Conceiving the criminal‐penal process as a tripartite rite of passage, the article originates the concept of ‘Ritual Individualization’ (RI). RI's creative pre‐sentencing casework accomplishes four key transformations in how the person is re‐presented to the court for sentencing. First, the person's unique voice and personal story is revealed, exhibiting her as a freely participating individual. Secondly, in doing so, the pertinence of social disadvantage tends to be minimized. Thirdly, ambiguous admissions of guilt are translated as freely‐given, full, and sincere confessions. Fourthly, the person is manifested as a culpable offender ready for punishment. The article considers new research agendas opened up by the implications of Ritual Individualization.     

The identification of the emulsifier component of emulsion explosives by liquid chromatography-mass spectrometry

ABSTRACT: The widespread availability of emulsion explosives for commercial blasting has inevitably lead to their diversion for criminal misuse. Present techniques for the characterization of emulsion explosives and their residues is generally based on the detection and identification of the oxidizer and the hydrocarbon components. Use of these components is problematic for residue identification because ammonium nitrate, waxes, and oils are relatively common in the urban environment and even their co-detection does not exclude them being sourced from materials other than explosives. The detection of the emulsifier component offers increased evidential value as certain emulsifiers used in explosive formulations are manufactured for that specific use, or have limited environmental distribution. In the current study liquid chromatography-mass spectrometry (LC-MS) was utilized for the characterization of two emulsifiers in common use; ethanolamine adducts of polyisobutylene succinic anhydride and sorbitol mono-oleate (SMO). The LC-MS technique enabled the detection of both emulsifiers in preblast samples; however, only SMO was detected in postblast residues. The analysis of the hydrocarbon component by gas chromatography-mass spectrometry was achieved in the same procedure.     

Dependency on natural resources: post-conflict challenges for livelihoods security and environmental sustainability in Goma,The Democratic Republic of Congo

High dependency on natural resources in post-conflict Goma caused severe damages to Virunga National Park (VNP) and Kivu Lake. Understanding the impacts of conflict on livelihoods and conservation activities is paramount in Goma. The main reasons for resource degradation here are heightened insecurity, theft, and uncertainty, which limit the use of far off land for agriculture. Consequently, most people depended on forest products and fish from protected areas, thereby causing higher risks of depletion of fish and park resources. High population density, few livelihoods alternatives, unpredictability, and weak state apparatus remain serious issues to be considered in resource conservation.

La dépendance aux ressources naturelles : les défis d'après-conflit pour la sécurité des moyens d'existence et pour la durabilité environnementale à Goma, République Démocratique du Congo

La haute dépendance aux ressources naturelles à Goma pendant la période après-conflit a provoqué des dégâts sévères au Parc National de Virunga (VNP) et au Lac Kivu. Il est de la plus haute importance que l'on comprenne les effets du conflit sur les moyens d'existence et sur les activités écologiques à Goma. Les causes principales de la diminution des ressources dans cette région sont une augmentation de l'insécurité, des vols, et l'incertitude ; ces facteurs réduisent l'exploitation de terres lointaines pour l'agriculture. Par conséquent, la plupart des gens comptaient sur ce qu'ils trouvaient dans les forêts et sur les poissons pêchés dans les zones protégées, ce qui a mené un risque élevé de diminution des ressources aquatiques et territoriales au parc national. La densité de la population, le manque d'autres moyens d'existence, l'imprévisibilité et la faiblesse de l'appareil de l'Etat restent des questions primordiales pour la protection des ressources.

Dependencia en los recursos naturales: retos del post-conflicto para la seguridad de los medios de vida y la sostenibilidad ambiental en Goma, República Democrática del Congo

En el escenario post-conflicto de Goma, se creó una fuerte dependencia de los recursos naturales, la cual provocó daños severos al Parque Nacional de Virunga y al Lago Kivu. Resulta de fundamental importancia comprender los impactos que los conflictos producen en los medios de sustento y en las actividades de conservación en Goma. La creciente inseguridad, el robo y la incertidumbre constituyen las razones principales de la degradación de los recursos debido a que inhiben el uso de tierras lejanas para la agricultura. En consecuencia, la mayoría de las personas depende de productos forestales y de la pesca en áreas protegidas, situación que provoca el aumento del riesgo tanto del agotamiento de peces como de los recursos del parque. Las políticas orientadas a la conservación de los recursos tendrán que considerar, además, otros temas graves, como lo son la alta densidad poblacional, las pocas alternativas para generar ingresos, la incertidumbre y la débil presencia del Estado.

Dependência de recursos naturais: desafios pós-conflito para a segurança dos meios de subsistência e sustentabilidade ambiental em Goma, República Democrática do Congo

A alta dependência de recursos naturais em Goma, no pós-conflito, causou graves prejuízos para o Virunga National Park (VNP) e Kivu Lake. Compreender os impactos do conflito sobre os meios de subsistência e atividades de conservação é algo crucial em Goma. As principais razões para a degradação dos recursos aqui são o aumento da insegurança, roubo e incerteza, o que limita o uso de terras distantes para a agricultura. Consequentemente, a maioria das pessoas dependia de produtos florestais e de peixe de áreas protegidas, causando assim maior risco de escassez de peixes e de recursos do parque. A alta densidade populacional, as poucas alternativas de meios de subsistência, a imprevisibilidade e o fraco aparato do estado permanecem sendo questões sérias que devem ser consideradas para a conservação de recursos.
