Using Optical Satellite Imagery to Monitor and Understand Agricultural Land-cover Change
(2020-06)
The activities of humans have transformed the earth over the last decades. The transformation is estimated to increase further in response to the growing world population. This has caused many countries to devise means to utilize resources sustainably. Bio-economy is seen as a means to reduce the high reliance on fossil materials and ensure the provision of raw materials, energy and food to the increasing world population in a sustainable manner. However, the rising demands for biomass to produce bioenergy have relied ...

Upgrading Starchy Staples for Tackling Malnutrition in South-West Ethiopia
(2018)
Child undernutrition is a critical public health challenge in Ethiopia. One of the immediate causes of child undernutrition is inadequate dietary intake as a result of relying on one or few starchy staples. Utmost attention should be given to improving diets of infants and young children if significant and fast changes are to be seen in the reduction of undernutrition. This dissertation examines the potentials of utilising appropriate food processing technologies for developing upgraded food products for infants and ...

Genotypic differences in body weight and physiological response of local and exotic turkeys challenged with Salmonella typhimurium
(2021-11-02)
To better understand susceptibility and/ or tolerance of locally adapted turkey to salmonellosis, we compared bodyweight, antibody titres and physiological traits based on genotype and sex of salmonella-infected turkeys. Three hundred poults from two genotypes (160 local and 140 exotic turkeys) were raised for twenty weeks. Bodyweight (BW), rectal temperature (RT), pulse rate (PR) and respiratory rate (RR) were measured weekly. Blood samples were collected from each turkey before and after inoculations at week 8 and ...

Drivers of adaptation to climate change in vulnerable farming communities: a micro analysis of rice farmers in Ndop, Cameroon
(2021-11-04)
Farmers in developing economies often struggle to adapt to climate change and their decisions to adapt usually hinges on perception and prevailing socio-economic factors. This study examines factors controlling farmers’ decision to adapt to climate change and evaluate the impact of such decisions on farm output. Using primary data from 138 rice farming households in Ndop-Cameroon, we employ the probit model with endogenous switching regression to investigate the impact of the farmers’ adaptation decisions on output. ...

A comparative cost-benefit analysis between fairtrade certified and non-certified cocoa production in the South-West region of Cameroon
(2021-12-31)
In order to promote cocoa agroforestry by encouraging cocoa farmers to integrate fruit trees inside their cocoa orchards, cocoa certification was initially launched since 2012 in Cameroon. Nowadays, cocoa certification is adopted by a few farmers and makes up only 3% of the national cocoa production. Using the most predominant Fairtrade certification in the South-West region, this study compared certified and non-certified cocoa production via a cost-benefit analysis. The results indicated that, in spite of its ...

Determinants of participation in rural non-farm economy in Zvimba District, Zimbabwe
(2019-11-06)
The capacity of agriculture to provide sustainable livelihood opportunities is exceeded by the rural populations of developing countries, and with limited opportunities available in urban centres, the rural non-farm economy (RNFE) becomes pivotal in improving rural livelihoods. Within an empowerment agenda, it is important for policy makers to understand why households enter into the RNFE. We investigated participation in the RNFE of farm worker livelihoods along with the motivation for participation in RNF employment. ...

Effect of different mechanical seed scarification methods on germination and emergence dynamics of baobab (Adansonia digitata L.)
(2021-10-28)
The African baobab (Adansonia digitata L.) is a multipurpose fruit-producing tree that is indigenous to the African savannahs. Commercial interest in the species has grown in recent years. The major obstacle of seed-based propagation of baobab is its inherent seed dormancy. Therefore, in this study the effects of different mechanical seed scarification methods on seed germination parameters and seedling development of A. digitata were tested. The results show that mechanical scarification had a significant effect on ...

Scaling up community-based goat breeding programmes via multi-stakeholder collaboration
(2020-05-01)
Community-based livestock breeding programmes (CBBPs) have emerged as a potential approach to implement sustainable livestock breeding in smallholder systems. In Malawi and Uganda, goat CBBPs were introduced to improve production and productivity of indigenous goats through selective breeding. Scaling up CBBPs have recently received support due to evidence-based results from current implementation and results of CBBPs implemented in other regions of the world. This paper explores strategies for scaling up goat CBBPs ...

Mixed method survey of vegetable farming and rural farmers’ livelihood in Enugu State, Nigeria
(2021-12-07)
Studies on the role of agriculture on the improvement of livelihood of farmers have primarily focused on staple crops. Increased awareness on the importance of vegetables in urban and rural areas in Nigeria has led to a rise in demand of vegetables. In both rural and urban communities, smallholder farmers are responding to this demand by increasing vegetable production and thereby creating economic opportunity for themselves. The purpose of this paper is to assess the role of vegetable farming on rural farmers’ ...
