The Interactions of Human Mobility and Farming Systems on Biodiversity and Soil Quality in the Western Highlands of Cameroon

Christopher Mubeteneh Tankou

Publication Year: 2014

Population growth and the drop in the returns from the major cash crop (coffee) for small farmers are the main drivers that have influenced the farming systems and mobility of farmers in the Western Highlands of Cameroon. The main objective of the research that led to this book was to determine the interactions between farming systems and human mobility in this region of Cameroon. A comparative study was conducted through household and field surveys in three villages and conceptualized based on the systems approach. The different types of mobility were influenced by household social factors, the quest for ëhigh valuedí farm plots and hired labour. Urban-rural migration contributed to occupation diversification and social mobility. The sustainability factor was a function of land use intensity, intensity of off-farm inputs, the household adjustment factor and mobility of the household. The sacred groves were rich in plant diversity of varied ecological and economic importance. Nitrogen mining was common at all levels of the farming system. These determinants and types of mobility claims are pertinent to the research area; the sustainability results of the farming systems reflect the reality on the ground; the nutrient flux evaluated at the crop and farm levels constitute a valuable database for future research.

Human mobility takes a wide variety of forms from permanent migration between regions to diurnal movements such as commuting to work (Parnwell, 1993). These movements generate flux in population numbers and carve out pathways in time and space. Capturing these movements is critical to understanding the use of space and place as mobility almost inevitably affects people’s...

This article analyses human mobility among the inhabitants of Cameroon’s most populous region, the Western Highlands of Cameroon. In order to capture the impact of various determinants on human mobility, a comparative study was conducted through household and field surveys in three villages in the region,the study based on the systems approach. The drop in coffee prices coupled with demographic pressure was a major determinant of mobility and land-use changes...

Smallholder farming systems in the Western Highlands of Cameroon (WHC) have undergone changes in land use, productivity and sustainability. Understanding the determinants that influence the system is essential when targeting appropriate intervention strategies for improvement. A field survey was carried out in three villages in this agro-ecological zone and analysed to understand the sustainability,...

This study was conducted in order to estimate species richness and diversity in different ecosystems and understand the floristic changes resulting from variation in abiotic factors in sacred groves. Vegetative assessment in quadrats revealed that the sacred groves were rich in plant genetic diversity composed of a total of 42, 65 and 82 ethno-botanical species of herbs, shrubs and trees respectively, of varied ecological and economic importance. The herbaceous α-diversity was significantly...

Soil nutrient depletion is a major constraint in agricultural development in sub-Saharan Africa. A study was conducted in the Western Highlands of Cameroon to assess soil nutrient balance and identify household and farm characteristics influencing soil nutrient balance using the procedures outlined in the NUTMON Tool-box. This is based on the assessment of the stocks and flows of nitrogen (N), phosphorus (P), and potassium (K) through the inputs (mineral fertilizers, organic...

The responses of the inhabitants of the Western Highlands of Cameroon (WHC) to an increase in population pressure and economic stress have brought about rural-rural mobility, rural-urban commuting, rural-urban migration, urban-rural migration and occupational diversification. The interaction between the human mobility patterns and farming systems, have effected change in the biodiversity and soil quality in the area. This study has made an...

This thesis draws on the findings from studies conducted between 2009 and 2011 in the Western Highlands of Cameroon. Population growth and a significant drop in the returns from the major cash crop for small farmers are the main drivers that have accounted for rural-urban and rural-rural interactions shaping the local economies and livelihoods of large numbers of people in Cameroon in general and the Western Highlands of Cameroon (WHC) in...

Dit proefschrift is gebaseerd op de resultaten van onderzoek dat is uitgevoerd tussen 2009 en 2011 in de Westelijke Hooglanden van Kameroen. De belangrijkste oorzaken die hebben bijgedragen aan de interacties tussen de ruraal- urbane gebieden en de rurale gebieden onderling zijn bevolkingsgroei en een aanzienlijke terugval in de inkomsten van de belangrijkste cash crop voor kleine boeren. Deze wisselwerking heeft de lokale economieën en bestaansmogelijkheden...

La présente thèse est basée sur les études menées entre 2009 et 2011 dans les hauts Plateaux de l’Ouest Cameroun. La croissance démographique et la baisse significative des revenus des producteurs agricoles issus du caféier, principale culture de rente, sont les principaux facteurs à l’origine des interactions entre les milieux ruraux et urbains d’une part et entre milieux ruraux d’autre part. Ces facteurs ont aussi façonné les économies locales et les modes de vie des...
