The main goal of the study is to quantify the effects of a) change in nitrogen fertilization rate, b) adjustment of sowing date, c) implementation of new cultivars, and d) supplementary irrigation on maize cropping systems across six African countries including Ghana, Nigeria, Kenya, Malawi, Ethiopia and Burkina Faso. For this purpose, 30 years (1980-2010) of climate data are used as well as soil and management information obtained from global datasets at 0.5° x 0.5° spatial resolution.
The paper makes significant contribution to the body of literature on the possible role of adaptation by farmers in Ghana particularly the fragile savannah ecological zone. The study explored smallholder farmers' responses to climate and ecological change effects on their livelihood activities that have emerged since the mid-1980s within the savanna agro ecological zone of Northern Ghana using an ethnographic approach.
This study aimed at conducting a semi-participatory assessment of simple biomass carbonization techniques and available feedstocks and measured the agronomic benefits for urban vegetable farmers in Tamale, Ghana, where urban horticulture is an important component of the local economy. The paper objectives were firstly to evaluate the potential of on-farm biochar production from crop residues and secondly to investigate the relevance of this technology to farmers’ economic realities
This presentation addresses the topic of sustainable agricultural intensification and gender- and age-biased land tenure systems in Africa.
The concept of an innovation platform is increasingly used in interventions inspired by agricultural innovation systems thinking, as a way of bringing stakeholders from a sector together to enable transformative change. An essential role on such innovation platforms is thought to be that of the ‘innovation champion’, but this role has so far not been unravelled.
Ghana’s cocoa production belt also serves as the main forests repository of the country. Cocoa farm- ing is both a direct and indirect driver of deforesta- tion in Ghana (UNEP, 2008). This implies that critical interventions are needed to deal with deforestation emanating from cocoa production.
We examine the impact of ambiguous and contested land rights oninvestment and productivity in agriculture in Akwapim, Ghana. Weshow that individuals who hold powerful positions in a local politicalhierarchy have more secure tenure rights and that as a consequencethey invest more in land fertility and have substantially higher output.The intensity of investments on different plots cultivated by a givenindividual corresponds to that individual’s security of tenure overthose specific plots and, in turn, to the individual’s position in thepolitical hierarchy relevant to those specific plot
This study explores one of the most important questions for alleviating poverty in sub-Saharan Africa, why are advancements in agricultural technology not taking root in this region? Using data from deep interviews of 42 small-scale farmers in Ghana and Cameroon, a conceptual analysis of drivers and factors of agricultural technology adoption in this region is made and represented as causal loop diagrams. Interviews also provide a basis for weighting factors that farmers consider before adopting a new technology.
In this paper, findings suggest that the uptake of social media is still in an early, exploratory phase associated with modest opportunities and relevant limitations of Web 2.0 mediated multi-stakeholder collaboration. Notably, there are gaps in giving and receiving feedback which are intrinsic to dyadic communication as well as innovation processes.
In this book, the authors assessed the role of biotechnology innovation for sustainable development in emerging and developing economies. This book compiles studies that each illustrate the potential, demonstrated value and challenges of biotechnology applications for sustainable agricultural innovation and/or industrial development in a national, regional and international context.
