The role of ligneous vegetation for livestock nutrition in the sub-Sahelian and Sudanian zones of West Africa: Potential effects of climate change

Climate change and variability in sub-Saharan West Africa is expected to have negative consequences for crop and livestock farming due to the strong dependence of these sectors on rainfall and natural resources, and the low adaptive capacity of crops farmers, agro-pastoralist and pastoralists in the region. The objective of this PhD research was to investigate the anticipated impacts of expected future climate change and variability on nutrition and grazing management of livestock in the prevailing extensive agro-pastoral and pastoral systems of the Sahelian and Sudanian zones of Burkina Faso. To achieve this, three studies were undertaken in selected village territories (100 km² each) in the southern Sahelian (Taffogo), northern Sudanian (Nobere, Safane) and southern Sudanian (Sokouraba) zone of the country during 2009 and 2010. The choice of two villages in the northern Sudanian zone was guided by the dichotomy between intense agricultural land use and high population density near Safane, and lower agricultural land use in the tampon zone between the village of Nobere and the National Park Kaboré Tambi of Pô. Using global positioning and geographical information systems tools, the spatio-temporal variation in the use of grazing areas by cattle, sheep and goats, and in their foraging behaviour in the four villages was assessed by monitoring three herds each per species during a one-year cycle (Chapter 2). Maximum itinerary lengths (km/d) were observed in the hot dry season (March-May); they were longer for sheep (18.8) and cattle (17.4) than for goats (10.5, p<0.05). Daily total grazing time spent on pasture ranged from 6 - 11 h with cattle staying longer on pasture than small ruminants (p<0.05). Feeding time accounted for 52% - 72% of daily time on pasture, irrespective of species. Herds spent longer time on pasture and walked farther distances in the southern Sahelian than the two Sudanian zones (p<0.01), while daily feeding time was longer in the southern Sudanian than in the other two zones (p>0.05). Proportional time spent resting decreased from the rainy (June - October) to the cool (November - February) and hot dry season (p<0.05), while in parallel the proportion of walking time increased. Feeding time of all species was to a significantly high proportion spent on wooded land (tree crown cover 5-10%, or shrub cover >10%) in the southern Sahelian zone, and on forest land (tree crown cover >10%) in the two Sudanian zones, irrespective of season. It is concluded that with the expansion of cropland in the whole region, remaining islands of wooded land, including also fields fallowed for three or more years with their considerable shrub cover, are particularly valuable pasturing areas for ruminant stock. Measures must be taken that counteract the shrinking of wooded land and forests across the whole region, including also active protection and (re)establishment of drought-tolerant fodder trees. Observation of the selection behaviour of the above herds of cattle and small ruminant as far as browse species were concerned, and interviews with 75 of Fulani livestock keepers on use of browse as feed by their ruminant stock and as remedies for animal disease treatment was undertaken (Chapter 3) in order to evaluate the consequence of climate change for the contribution of browse to livestock nutrition and animal health in the extensive grazing-based livestock systems. The results indicated that grazing cattle and small ruminants do make considerable use of browse species on pasture across the studied agro-ecological zones. Goats spent more time (p<0.01) feeding on browse species than sheep and cattle, which spent a low to moderate proportion of their feeding time on browsing in any of the study sites. As far as the agro-ecological zones were concerned, the contribution of browse species to livestock nutrition was more important in the southern Sahelian and northern Sudanian zone than the southern Sudanian zone, and this contribution is higher during the cold and hot dry season than during the rainy season. A total of 75 browse species were selected on pasture year around, whereby cattle strongly preferred Afzelia africana, Pterocarpus erinaceus and Piliostigma sp., while sheep and goats primarily fed on Balanites aegyptiaca, Ziziphus mauritiana and Acacia sp. Crude protein concentration (in DM) of pods or fruits of the most important browse species selected by goats, sheep and cattle ranged from 7% to 13% for pods, and from 10% to 18% for foliage. The concentration of digestible organic matter of preferred browse species mostly ranged from 40% to 60%, and the concentrations of total phenols, condensed tannins and acid detergent lignin were low. Linear regression analyses showed that browse preference on pasture is strongly related to its contents (% of DM) of CP, ADF, NDF and OM digestibility. Interviewed livestock keepers reported that browse species are increasingly use by their grazing animals, while for animal health care use of tree- and shrub-based remedies decreased over the last two decades. It is concluded that due to climate change with expected negative impact on the productivity of the herbaceous layer of communal pastures browse fodder will gain in importance for animal nutrition. Therefore re-establishment and dissemination of locally adapted browse species preferred by ruminants is needed to increase the nutritional situation of ruminant stock in the region and contribute to species diversity and soil fertility restoration in degraded pasture areas. In Chapter 4 a combination of household surveys and participatory research approaches was used in the four villages, and additionally in the village of Zogoré (southern Sahelian zone) and of Karangasso Vigué (northern Sudanian zone) to investigate pastoralists’ (n= 76) and agro-pastoralists’ (n= 83) perception of climate change, and their adaptation strategies in crop and livestock production at farm level. Across the three agro-ecological zones, the majority of the interviewees perceived an increase in maximum day temperatures and decrease of total annual rainfall over the last two decades. Perceptions of change in climate patterns were in line with meteorological data for increased temperatures while for total rainfall farmers’ views contrasted the rainfall records which showed a slight increase of precipitation. According to all interviewees climate change and variability have negative impacts on their crop and animal husbandry, and most of them already adopted some coping and adaptation strategies at farm level to secure their livelihoods and reduce negative impacts on their farming system. Although these strategies are valuable and can help crop and livestock farmers to cope with the recurrent droughts and climate variability, they are not effective against expected extreme climate events. Governmental and non-governmental organisations should develop effective policies and strategies at local, regional and national level to support farmers in their endeavours to cope with climate change phenomena; measures should be site-specific and take into account farmers’ experiences and strategies already in place.

Decent work?

Pastoralism and ranching are two different rangeland-based livestock systems in dryland areas of East Africa. Both usually operate under low and irregular rainfall and consequently low overall primary biomass production of high spatial and temporal heterogeneity. Both are usually located far from town centres, market outlets and communication, medical, educational, banking, insurance and other infrastructure. Whereas pastoralists can be regarded as self-employed, gaining their livelihood from managing their individually owned livestock on communal land, ranches mostly employ herders as wage labourers to manage the livestock owned by the ranch on the ranches’ own land property. Both production systems can be similarly labour intensive and – with regard to the livestock management – require the same type of work, whether carried out as self-employed pastoralist or as employed herder on a work contract. Given this similarity, the aim of this study was to comparatively assess how pastoralists and employed herders in northern Kenya view their working conditions, and which criteria they use to assess hardship and rewards in their daily work and their working life. Their own perception is compared with the concept of Decent Work developed by the International Labour Organisation (ILO). Samburu pastoralists in Marsabit and Samburu Districts as well as herders on ranches in Laikipia District were interviewed. A qualitative analysis of 47 semi-structured interviews yielded information about daily activities, income, free time, education and social security. Five out of 22 open interviews with pastoralists and seven out of 13 open interviews with employed herders fully transcribed and subjected to qualitative content analysis to yield life stories of 12 informants. Pastoralists consider it important to have healthy and satisfied animals. The ability to provide food for their family especially for the children has a high priority. Hardships for the pastoralists are, if activities are exhausting, and challenging, and dangerous. For employed herders, decent conditions are if their wages are high enough to be able to provide food for their family and formal education for their children. It is further most important for them to do work they are experienced and skilled in. Most employed herders were former pastoralists, who had lost their animals due to drought or raids. There are parallels between the ILO ‘Decent Work’ concept and the perception of working conditions of pastoralists and employed herders. These are, for example, that remuneration is of importance and the appreciation by either the employer or the community is desired. Some aspects that are seen as important by the ILO such as safety at work and healthy working conditions only play a secondary role to the pastoralists, who see risky and dangerous tasks as inherent characteristics of their efforts to gain a livelihood in their living environment.

Human and Raptor Interactions in the Context of a Nomadic Society

This research project focuses on contemporary eagle-taming falconry practice of the Altaic Kazakhs animal herding society in Bayan Ulgii Province in Western Mongolia. It aims to contributing both theoretical and empirical criteria for cultural preservation of Asian falconry. This cultural as well as environmental discourse is illustrated with concentrated field research framed by ecological anthropology and ethno-ornithology from the viewpoint of “Human-Animal Interaction (HAI)” and “Human-Animal Behavior (HAB)”. Part I (Chapter 2 & 3) explores ethno-archaeological and ethno-ornithological dimensions by interpretive research of archaeological artefacts which trace the historical depth of Asian falconry culture. Part II (Chapter 4 & 5) provides an extensive ethnographic narrative of Altaic Kazakh falconry, which is the central part of this research project. The “Traditional Art and Knowledge (TAK)” in human-raptor interactions, comprising the entire cycle of capture, perch, feeding, training, hunting, and release, is presented with specific emphasis on its relation to environmental and societal context. Traditional falconry as integral part of a nomadic lifestyle has to face some critical problems nowadays which necessitate preventing the complete disappearance of this outstanding indigenous cultural heritage. Part III (Chapter 6 & 7) thus focuses on the cultural sustainability of Altaic Kazakh falconry. Changing livelihoods, sedentarisation, and decontextualisation are identified as major threats. The role of Golden Eagle Festivals is critically analysed with regard to positive and negative impact. This part also intends to contribute to the academic definition of eagle falconry as an intangible cultural heritage, and to provide scientific criteria for a preservation master plan, as well as stipulate local resilience by pointing to successive actions needed for conservation. This research project concludes that cultural sustainability of Altaic Kazakh falconry needs to be supported from the angles of three theoretical frameworks; (1) Cultural affairs for protection based on the concept of nature-guardianship in its cultural domain, (2) Sustainable development and improvement of animal herding productivity and herder’s livelihood, (3) Natural resource management, especially supporting the population of Golden Eagles, their potential prey animals, and their nesting environment.

An integrated assessment of resource use strategies in the Borana pastoral system of southern Ethiopia

In the pastoral production systems, mobility remains the main technique used to meet livestock’s fodder requirements. Currently, with growing challenges on the pastoral production systems, there is urgent need for an in-depth understanding of how pastoralists continue to manage their grazing resources and how they determine their mobility strategies. This study examined the Borana pastoralists’ regulation of access to grazing resources, mobility practices and cattle reproductive performances in three pastoral zones of Borana region of southern Ethiopia. The central objective of the study was to contribute to the understanding of pastoral land use strategies at a scale relevant to their management. The study applied a multi-scalar methodological approach that allowed zooming in from communal to individual herd level. Through participatory mapping that applied Google Earth image print out as visual aid, the study revealed that the Borana pastoralists conceptualized their grazing areas as distinctive grazing units with names, borders, and specific characteristics. This knowledge enables the herders to communicate the condition of grazing resources among themselves in a precise way which is important in management of livestock mobility. Analysis of grazing area use from the participatory maps showed that the Borana pastoralists apportion their grazing areas into categories that are accessed at different times of the year (temporal use areas). This re-organization is an attempt by the community to cope with the prevailing constraints which results in fodder shortages especially during the dry periods. The re-organization represents a shift in resource use system, as the previous mobility practice across the ecologically varied zones of the rangelands became severely restricted. Grazing itineraries of 91 cattle herds for over 16 months obtained using the seasonal calendar interviews indicated that in the areas with the severest mobility constraints, the herders spent most of their time in the year round use areas that are within close proximity to the settlements. A significant change in mobility strategy was the disallowing of foora practice by the communities in Dirre and Malbe zones in order to reduce competition. With the reduction in mobility practices, there is a general decline in cattle reproductive parameters with the areas experiencing the severest constraints showing the least favourable reproductive performances. The study concludes that the multi-scalar methodology was well suited to zoom into pastoral grazing management practices from communal to individual herd levels. Also the loss of mobility in the Borana pastoral system affects fulfilment of livestock feed requirements thus resulting in reduced reproductive performances and herd growth potentials. While reversal of the conditions of the situations in the Borana rangelands is practically unfeasible, the findings from this research underscore the need to protect the remaining pastoral lands since the pastoral production system remains the most important livelihood option for the majority of the Borana people. In this regards the study emphasises the need to adopt and domesticate regional and international policy frameworks such as that proposed by the African Union in 2010.

From Subsistence Agriculture to Commercial Enterprise: Community management of green technologies for resilient food production

The aim of this paper is to emphasize the capacity and resilience of rural communities in regard to sustainable food security by adopting innovative approaches to irrigation. The shift from subsistence to commercial agriculture is promoted as a means to sustainable development. An analysis of the efficacy of irrigation schemes in Zimbabwe suggests that, in terms of providing sustainable agricultural production, they have neither been cost-effective nor have they provided long-term food security to their beneficiaries. This is certainly true of Shashe Scheme and most others in Beitbridge District. The Shashe Irrigation Scheme project represents a bold attempt at developing a fresh approach to the management of communal land irrigation schemes through a Private Public Community Partnership. The model illustrated represents a paradigm shift from subsistence agriculture to a system based on new technologies, market linkages and community ownership that build resilience and lead to sustainable food security and economic prosperity.

El uso de los Consejos Comunitarios de Gobierno como propaganda política por el gobierno de Álvaro Uribe Vélez en su primer periodo

El proyecto político del ex Presidente Álvaro Uribe Vélez se presentó como una novedad histórica, articulada alrededor de la lucha contra el terrorismo y se creía que era la única salida eficaz a la situación de violencia que se venía generando en Colombia cincuenta años atrás. El estilo político de gobierno y la imagen personal de Álvaro Uribe Vélez marcó una ruptura significativa con relación a sus antecesores y a otros importantes dirigentes políticos de Colombia, ya que se tenía la concepción de que los anteriores gobiernos se caracterizaron por la incapacidad para enfrentar el conflicto armado. Esta novedad se vio reflejada no solamente en las medidas y políticas propuestas e implementadas desde comienzos de su administración, sino en toda una serie de estrategias tendientes a capturar la atención de los medios de comunicación y el respaldo de la ciudadanía al programa de gobierno en general y a la política de seguridad democrática en particular. Los consejos comunales de gobierno celebrados en los departamentos de Vichada y Chocó durante 2002 y 2006, incidieron en los resultados de las votaciones presidenciales del 2006 a favor de Álvaro Uribe Vélez. Esto es así dada la propaganda política que se hizo en ellos de la imagen del presidente y el uso de algunas reglas especiales que permitieron persuadir al electorado. Como se pudo observar, los consejos comunales hacían especial énfasis en las cualidades atrayentes del presidente: carácter, credibilidad, dinamismo, carisma y liderazgo. El uso de las 5 reglas explicadas: aprovechamiento de los deseos preexistentes de la audiencia, la apelación a las emociones, la simplificación de las emociones, la repetición de los temas principales y las afirmaciones declarativas directas, finalmente pretendían vender al presidente como un político sui generis, con unas cualidades excepcionales y como el único capaz de asumir los problemas de las regiones con autoridad y decisión. Esto sumado al vínculo emocional que siempre generaba con el público, catalizó su efecto propagandístico.

Una lectura crítica sobre la política de participación ciudadana promovida por el gobierno de Álvaro Uribe Vélez. Caso de estudio: los Consejos Comunales de Gobierno. Periodo de estudio: 2002-2010.

Uno de los objetivos perseguidos en los Consejos Comunales de Gobierno, celebrados por la administración de Álvaro Uribe Vélez en Colombia (2002-2010), fue la promoción de la participación ciudadana. Partiendo de la ambigüedad de lo que este objetivo puede significar o perseguir, nos propusimos hacer una revisión inicial de estudios que han analizado y avanzado en la teorización de diversos ejercicios de participación ciudadana en Colombia y en el mundo, así como del concepto de ciudadanía activa, el cual ha sido desarrollado por diversas tradiciones de pensamiento en contextos diversos, incluidos los escenarios de participación ciudadana. Para el análisis de los Consejos Comunales de Gobierno -ejemplo del tipo de participación que se promovió por el gobierno de Álvaro Uribe Vélez-, nos concentramos en tres aspectos: una exposición general de la institucionalidad desarrollada para la participación ciudadana en Colombia; la caracterización del gobierno bajo el que se promovieron estos consejos; y el análisis del diseño institucional particular a estos. Teniendo en cuenta el carácter de la política de participación impulsada por el gobierno de Álvaro Uribe Vélez, la tradición institucional para la participación en Colombia, y el particular desarrollo de éstos consejos, se formulan al final unas reflexiones y recomendaciones con respecto a las iniciativas de gobierno para la participación ciudadana.

Las manifestaciones del poder constituyente y el poder constituido en la construcción de consejos comunales en el Estado Táchira, Venezuela (2005 - 2012)

La presente monografía busca proveer elementos de análisis acerca del proceso de construcción de consejos comunales que ha tenido lugar en la Venezuela contemporánea. Por sus rasgos diferenciadores y llamativos, el caso particular escogido es el del Estado Táchira. El trabajo se enfocará en las características y modos de operación de los actores que ostentan un rol preponderante en el proceso. De igual modo, se recurrirá a los planteamientos teóricos fundamentales de Antonio Negri en lo relacionado con los conceptos de poder constituyente y poder constituido, con el objetivo de abordar las interacciones de dichos actores. Se afirma que la dinámica de colaboración-confrontación que distingue aquellas interacciones, se puede analizar a la luz del dualismo que protagonizan las manifestaciones de los poderes recién mencionados. Este aspecto arroja información valiosa para procurar la comprensión del fenómeno en cuestión.

Biodiversidad, cultura y territorio

After several decades of systematic nature destruction, the discourse on biodiversity is the answer of what might be called “the irruption of the biological”, i.e. the biotic issue surviving as the core issue of the modern order. In this regard, the biodiversity discourse declares itself the sponsor of saving nature from destructive practices and capable to institute a culture of conservation instead. Nevertheless, there remain gaps in the discourse, which have been intended to be fi lled with discussions addressing lately the relevance of the local knowledge, the ways of life –habits and customs– and the traditional production, within the frame that supports the meaning of biodiversity. On the one hand, for industrialized countries governments and international governmental institutions, traditional knowledge is an asset of the humankind, which improved becomes a technological innovation that may be subject to patent and fi nally traded, without any benefit to the owners of the basis knowledge. On the other hand, for peasants, intellectuals, and local knowledge activists, ways of life and tradicional production are the basis for rebuilding the peasants’ and natives’ territory, to strengthen the limited independence and self-suffi ciency they live with, but with their active involvement in the determination of everything that affects them. Based on these considerations, spaces are being built to provide an answer to privatization, an answer based on the concept of “the communal” (Grain, 2005).

La importancia estratégica de los Altos del Golán en el conflicto Sirio-israelí y su incidencia en la comunidad Drusa Siria (1967-1981)

El presente estudio de caso es un análisis sobre el conflicto entre Siria e Israel a partir de la disputa por los Altos del Golán, luego de la ocupación por parte de Israel al finalizar la Guerra de los Seis Días. A diferencia de la mayoría de los trabajos que se realizan sobre Medio Oriente, este trabajo busca diferenciarse de los estudios sobre el conflicto árabe-israelí, enfocándose en el conflicto sirio-israelí. Adicionalmente, se trata un tema poco común como son las implicaciones que este conflicto ha tenido sobre la comunidad drusa siria, población que quedó en medio de las disputas por los Altos del Golán. Teniendo en cuenta lo anterior, se hará un análisis a partir del Interés Nacional que motiva tanto a Siria como a Israel y a la comunidad drusa que ahí habita a seguir en la disputas por este territorio, que gracias a sus características geográficas representa un punto estratégico en la región.

La experiencia de los receptores en el trasplante de órganos y tejidos

El trasplante de órganos y/o tejidos es considerado como una opción terapéutica viable para el tratamiento tanto de enfermedades crónicas o en estadios terminales, como de afectaciones no vitales, pero que generen una disminución en la calidad de vida percibida por el paciente. Este procedimiento, de carácter multidimensional, está compuesto por 3 actores principales: el donante, el órgano/tejido, y el receptor. Si bien un porcentaje significativo de investigaciones y planes de intervención han girado en torno a la dimensión biológica del trasplante, y a la promoción de la donación; el interés por la experiencia psicosocial y la calidad de vida de los receptores en este proceso ha aumentado durante la última década. En relación con esto, la presente monografía se plantea como objetivo general la exploración de la experiencia y los significados construidos por los pacientes trasplantados, a través de una revisión sistemática de la literatura sobre esta temática. Para ello, se plantearon unos objetivos específicos derivados del general, se seleccionaron términos o palabras claves por cada uno de estos, y se realizó una búsqueda en 5 bases de datos para revistas indexadas: Ebsco Host (Academic Search; y Psychology and Behavioral Sciences Collection); Proquest; Pubmed; y Science Direct. A partir de los resultados, se establece que si bien la vivencia de los receptores ha comenzado a ser investigada, aún es necesaria una mayor exploración sobre la experiencia de estos pacientes; exploración que carecería de objetivo si no se hiciera a través de las narrativas o testimonios de los mismos receptores

De la investigación se concluye que las empresas que logran crear estrategias comunitarias y relaciones estrechas entre ellas, tienden a tener mejores utilidades en el largo plazo y ser empresas más sostenibles.

Asymmetrically fair rules for an indivisible good problem with a budget constraint

We study a particular restitution problem where there is an indivisible good (land or property) over which two agents have rights: the dispossessed agent and the owner. A third party, possibly the government, seeks to resolve the situation by assigning rights to one and compensate the other. There is also a maximum amount of money available for the compensation. We characterize a family of asymmetrically fair rules that are immune to strategic behavior, guarantee minimal welfare levels for the agents, and satisfy the budget constraint.

Há uma gota de sangue em cada museu : a ótica museológica de Mário de Andrade

Há uma gota de sangue em cada museu: a ótica museológica de Mário Andrade (M.A.) é uma dissertação de mestrado que aborda o pensamento museológico do autor de Macunaíma através da análise de seus escritos, de sua coleção particular e de suas práticas à frente do Departamento de Cultura da cidade de São Paulo e do Serviço do Patrimônio Histórico e Artístico Nacional. Três questões orientam a presente dissertação: 1a. Até que ponto as propostas museológicas de M.A. representam consolidação ou rompimento com o pensamento modernista? 2a. Como se colocam na obra de M.A. as questões referentes à identidade nacional e cultura popular? 3a. Sendo o museu um lugar privilegiado de construção de memória, não seria também um baluarte da tradição? Em que sentido um museu pode ser ruptura? Como são tratadas as idéias de coleção e museu pelo poeta modernista? O enfrentamento destas questões, aliado ao entendimento de que a gota de sangue é gota de humanidade e sinal de historicidade presente nos museus, constitui a base desse estudo.
