Emerging Development Pathways of Urban Livestock Production in Rapidly Growing West Africa Cities
(2016-11-19)
In this study, we try to capture the degree of specialization or integration, and of intensification or extensification, of (peri-) urban livestock production, along with the factors that influence such decisions and their impact on natural resource uses. A total of 181 and 187 structured questionnaires were completed in livestock-keeping households in Ouagadougou (Burkina Faso) and Tamale (Ghana). Categorical principal component and two-step cluster analysis were used to identify homogenous groups of livestock-keeping ...

Participatory Mapping as an Approach to Identify Grazing Pressure in the Altay Mountains, Mongolia
(2018-06-11)
Sustainable rangeland management is crucial for maintaining forage resources in pastoral systems, globally. However, pastoral regions are often remote and therefore data poor when it comes to resource monitoring. We tested participatory mapping as a means to rapidly assess rangeland use to identify areas with high grazing pressure. Participatory geographic information system data and herbaceous biomass production data were collected and georeferenced to establish a grazing pressure index for a summer pasture in the ...

Determinants of resource use and use efficiency in urban and peri-urban dairy, beef cattle and pig production units in Ouagadougou, Burkina Faso (West Africa)
(2019)
The (peri-) urban demand for food of animal origin is increasing in sub-Saharan Africa as a result of the rapidly growing population and urbanisation. Livestock production in the vicinity of West African cities is well established but currently undergoes changes triggered by key transforming factors such as access to resources, production management related to famers' knowledge or know-how, increasing demand for livestock and/or animal products, policies and the legal framework in which livestock production systems ...

Evolution of Rural Livelihood Strategies in a Remote Sino-Mongolian Border Area: A Cross-Country Analysis
(2018-03-29)
Ecologically sound natural resources management is still the backbone of rural livelihoods in many regions of the world. The Altai-Dzungarian region between China and Mongolia constitutes an ideal site to study how political, economic, infrastructural, and cultural differences affect rural livelihoods. Structured semi-quantitative interviews were conducted with 483 households on both sides to characterise their current livelihood strategies and assess the importance of the various activities for the households’ current ...

Phenotypic diversity, major genes and production potential of local chickens and guinea fowl in Tamale, northern Ghana
(2017-06-26)
Objective:
Our study provides information on phenotypes of local chickens and guinea fowl and their body measures as well as on major genes in local chickens in northern Ghana.
Methods:
Qualitative and morphometric traits were recorded on 788 local chickens and 394 guinea fowl in urban households in Tamale, Ghana.
Results:
The results showed considerable variation of color traits and numerous major genes in local chickens, while color variations and related genotypes in guinea fowl were limited. In local chickens, ...

The relevance of herders’ local ecological knowledge on coping with livestock losses during harsh winters in western Mongolia
(2018-01-29)
In many regions of the world, traditional and local ecological knowledge is still important today for coping with environmental challenges. This study explored the relevance of such knowledge for predicting and coping with harsh winter conditions (dzud) in a remote area of western Mongolia, where government support to disaster-affected herders is restricted by weak infrastructure. Structured face-to-face interviews were held in 50 households (HHs), addressing aspects of livestock possession and management as well as ...

Interrelatedness of grazing livestock with vegetation parameters and farmers’ livelihoods in the Mahafaly region, southwestern Madagascar
(2015-10-27)
The study aims to get deeper insight into the highly extensive system of animal husbandry in the Mahafaly region of southwestern Madagascar. It tries to understand the major drivers for pastoral dynamics, land and resource use along a gradient in altitude and vegetation to consider the area’s high spatial and temporal heterogeneity. The study also analyzes the reproductive performance of local livestock as well as the owners’ culling strategies to determine herd dynamics, opportunities for economic growth, and future ...

Opportunities and constraints of transhumant small ruminant production in the Chinese Altay Mountains
(2016-08-16)
This PhD thesis focuses on current livelihoods of agro-pastoral livestock keepers, their animal nutrition, herd and rangeland management strategies. It thereby aims to contribute to sustainable rangeland management, livestock production and household income in Qinghe county of the Chinese Altay Mountain region, located in Xinjiang Uyghur Autonomous Region, PR China.
In its first part the study characterizes the socio-economic situation and agricultural practices of agro-pastoralists through structured household ...
Dissertation
Herd management and livestock productivity in the Altai region of Western Mongolia
(2016-08-17)
This thesis analyses the influence of qualitative and quantitative herbage production on seasonal rangelands, and of herd and pasture use strategies on feed intake, body mass development and reproductive performance of sheep and goats in the Altai mountain region of Bulgan county (soum) in Khovd province (aimag). This westernmost county of Mongolia is characterized by a very poor road network and thus very difficult access to regional and national markets. The thesis explores in this localized context the current ...

The role of ligneous vegetation for livestock nutrition in the sub-Sahelian and Sudanian zones of West Africa: Potential effects of climate change
(2012-12-07)
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 ...
