DS201510-1783 2015 | Lombard, L. | Threat economies and armed conservation in northeastern Central African Republic. | Geoforum, in press available | Africa, Central African Republic | CSR |
| Abstract: This article, based on ethnographic and archival research in the northeastern parklands of the Central African Republic (CAR), explores the area’s history of armed conservation. Critical scholarly accounts of armed conservation practices and projects often starkly contrast the people involved in them: there are agents of the state, or state-like actors, who seek to dominate, territorialize, and discipline, often using violence to do so, and there are local populations who are dispossessed of their lands and resources without compensation and forced into new kinds of poverty, despite rhetoric and practices meant to inculcate "local participation". The case presented here forces us to re-think these accounts. Rather than pursuing authority in the sense of expanding control over other people, people in northeastern CAR (whether putatively in favor of or opposed to conservation) are working to create and maintain access to the status of an income. To do so they engage in practices of threatening and hiding. While the means to use physical force are not equally shared, capacities to threaten and hide are widely held, and organizational and other hierarchies are unstable, making it difficult to describe any of this as a matter of domination and resistance. Expanding on literature that examines processes of green militarization (Lunstrum, 2014), the article focuses on the interactional dynamics of armed conservation to show that threats are as important as acts of physical violence, and that hiding-whether in the bush or plain sight-is critical to understanding armed conservation in an area where the state is largely seen as absent. |
DS201701-0024 2016 | Partnership Africa Canada | From conflict to illicit mapping the diamond trade from Central African Republic to Cameroon. | Partnership Africa Canada, 36p. Pdf | Africa, Central African Republic, Cameroon | History |
| Abstract: The Central African Republic (CAR) is the only source of traditionally defined conflict diamonds in the world today. Since May 2013, exports of its diamonds have been under international embargo by both the United Nations and the Kimberley Process (KP), the initiative that regulates the production and trade of rough diamonds. CAR was suspended from the KP after a March 2013 coup d’état that sparked widespread civil unrest in the country. The coup was the inevitable outcome of years of political instability forged by a coalition of rebel groups, known as Séléka, who attacked the government and incrementally seized territory, including the strategic diamond-mining town of Bria.2 On March 24, 2013 Séléka captured the capital city of Bangui and overthrew the government, initiating a bitter internal conflict that continues to fester to this day. The civil war and regime change forced the United Nations and the international community to impose economic sanctions on CAR. Not only were all diamond exports prohibited, the KP urged diamond-trading countries to exercise enhanced vigilance and ensure that diamonds produced in CAR were seized and not allowed to circulate in legitimate trade.3 While the ban on CAR’s exports was partially lifted in 2016 from regions deemed to be KP compliant, that has not stopped the flow of CAR’s conflict diamonds to international markets—while it was under full embargo or regions still prevented from trading today. This report examines the smuggling of diamonds from the Central African Republic into Cameroon. Further, it focuses on the impact this illicit trade has on Cameroon’s internal controls as well as the broader integrity of the diamond supply chain. The report describes the methods used and the key actors involved in this illicit trade. It concludes that the KP and frontline countries like Cameroon need to do more to interrupt the illicit trade of conflict diamonds from CAR and support each other in taking action. |

| Abstract: Carbonado diamond is found only in Brazil and the Central African Republic. These unusual diamond aggregates are strongly bonded and porous, with melt-like glassy patinas unlike any conventional diamond from kimberlites-lamproites, crustal collisional settings, or meteorite impact. Nearly two centuries after carbonado's discovery, a primary host rock compatible with the origin of conventional diamond at high temperatures and pressures has yet to be identified. Models for its genesis are far-reaching and range from terrestrial subduction to cosmic sources.

| Abstract: Structural peculiarities of several types of cryptocrystalline diamond varieties: carbonado, impact-related yakutite and cryptocrystalline diamond aggregates from kimberlite were studied using Infrared spectroscopy, X-ray diffraction contrast (DCT—Diffraction Contrast Tomography) and phase contrast tomography (PCT). It is shown that the porosity of the carbonado and kimberlitic cryptocrystalline aggregates is similar being in range of 5-10 vol %, possibly indicating similar formation mechanism(s), whereas that of yakutite is essentially zero. Crystallographic texture is observed for some carbonado samples. It is suggested that at least partially the texture is explained by deformation-related bands. Infrared spectroscopy reveals presence of hydrous and, probably, of hydrocarbon species in carbonado. |

| Abstract: Very few zircon-bearing, kimberlite-hosted mantle eclogite xenoliths have been identified to date; however, the zircon they contain is crucial for our understanding of subcratonic lithospheric mantle evolution and eclogite genesis. In this study, we constrain the characteristics of zircon from mantle eclogite xenoliths based on existing mineralogical and geochemical data from zircons from different geological settings, and on the inferred origin of mantle eclogites. Given the likely origin and subsequent evolution of mantle eclogites, we infer that the xenoliths can contain zircons with magmatic, metamorphic and xenogenic (i.e. kimberlitic zircon) origins. Magmatic zircon can be inherited from low-pressure mafic oceanic crust precursors, or might form during direct crystallization of eclogites from primary mantle-derived melts at mantle pressures. Metamorphic zircon within mantle eclogites has a number of possible origins, ranging from low-pressure hydrothermal alteration of oceanic crustal protoliths to metasomatism related to kimberlite magmatism. This study outlines a possible approach for the identification of inherited magmatic zircon within subduction-related mantle eclogites as well as xenogenic kimberlitic zircon within all types of mantle eclogites. We demonstrate this approach using zircon grains from kimberlite-hosted eclogite xenoliths from the Kasai Craton, which reveals that most, if not all, of these zircons were most likely incorporated as a result of laboratory-based contamination. |
