This thesis argues that the full impact of Agricultural Innovation Systems (AIS) driven research, that works to enhance not only agricultural production and productivity but also market linkages cannot be captured effectively using only microeconomic level studies; but rather requires the use of a combination of micro and macro-level analysis. This is because the innovation systems perspective entails the collaboration of different actors across the entire agricultural value chain. Therefore this study aimed to firstly quantify the degree to which AIS driven research impacts upon the livelihood outcomes of rural smallholder farmers. Second, the study aimed to determine the extent to which a combination of macro-economic and agricultural policy shocks impact upon household incomes in the maize-based farming system in Malawi; given macro-micro linkages as strengthened by AIS research. The first objective was tackled by using quasi-experimentation with propensity score matching to establish a valid counterfactual and single differencing to measure impact. The second objective was achieved by using a combination of quantitative and qualitative statistical and econometric tools to delve into the dynamics of the maize market at different levels and to develop a model that is capable of capturing the maize market dynamics. A multi-equation partial equilibrium model of the national maize market was therefore developed and linked in a top-down unidirectional manner to the local maize economy via a price-linkage equation. A non-behavioural arithmetic micro-accounting approach was adopted to estimate household incomes that were linked to the local economy, through which macroeconomic level maize price changes transmit. The results of the study empirically demonstrate that AIS driven research impacts positively upon the livelihood outcomes of rural households. This is demonstrated with participating households exhibiting statistically significant higher production outcomes (upland crop production, maize harvests, value of assets, and value of livestock); household incomes as well as human capital outcomes in some cropping seasons. In addition participating households also had much higher statistically significant fertilizer use prior to the implementation of the fertilizer subsidy program in the country; and statistically significant higher fertilizer use patterns for the first two cropping seasons following the implementation of the subsidy program. Participating households had greater linkages with the market economy which allowed them to take greater advantage of market incentives but which also made them more vulnerable to policy shocks. This study therefore shows that the analysis of the impacts of the paradigm shift in agricultural research towards an innovation system orientation cannot be contained at the household level, as this would lead to the formulation of inadequate policies that do not take into account the effects of greater market linkages of the rural households. Policy implications are that increasing production and productivity and linking farmers to markets may not in itself be enough for sustained livelihood improvement, as the resultant greater linkages to the market economy may be detrimental to household livelihood outcomes in the face of uncoordinated policies. In order for the paradigm shift in agricultural research towards an innovation systems perspective to be effective in sustaining an entrepreneurial culture in rural societies in Africa, there is need to foster the diversification out of agricultural enterprises for income, while supporting productivity improvements for food security. In addition any interventions should be implemented only after systematic analysis of the potential consequences of the resultant enhanced macro-micro linkages. This would help to ensure that there is no mismatch between policies and livelihood improvement strategies. / Thesis (PhD)--University of Pretoria, 2012. / Agricultural Economics, Extension and Rural Development / unrestricted

Thesis (LLM. (Management and Law)) -- University of Limpopo, 2013 / Rural areas of Zimbabwe suffered acute shortage of banking services. Conventional banks feared high transaction costs and lack of collateral associated with this market segment. This research aimed at evaluating impact of microfinance on rural farming sector. Finding out the general banking and microfinance situation, appraising scheme impact and making recommendations were the research’s objectives. A descriptive research design was used. A population of 3,400 members constituting 289 Investment Groups (IGs) was used. Quota and purposive sampling were used to select 20 IGs and 154 individual respondents. Sample survey, Focus Group Discussions (FGD) and Key Informant Interviews (KII) were data collection methods. The survey findings showed that the five Department For International Development’s (DFID’s) Sustainable Livelihoods Approach (SLA) asset bases increased more for the treatment than the control groups, signifying microfinance impact. Wealth ranking, meant to triangulate survey results, depicted upward mobility of groups; old ones transcending to rich categories while the new moved into top poor rank, also demonstrating impact. Further, scheme achieved women empowerment basing on their numerical predominance and improved self-confidence, signifying impact. The study recommends that Farmers’ Association of Community self-Help Investment Groups (FACHIG) resuscitated its savings component using the Self-Help Group (SHG) thrift approach to ensure scheme sustainability. In addition, climate change, a phenomenon which increased droughts, could have dampened impact. However, the research did not delve into this area, compelling a future study.
