    An assessment of the impact of supply chain risk management in food-aid distribution in Zimbabwe
    (2020-09) Ngarize, Peter; Ngcamu, Bethuel Sibongiseni
    The present study sought to investigate and interrogate supply chain risks prevalent in the humanitarian sector with reference to food-aid distribution and to also assess the impact of supply chain risk management as a strategy for cost- effective food-aid distribution operations in Zimbabwe. The global increase of disasters and their devastating effects has left communities vulnerable and in need of help from Donors, humanitarian agencies and the host governments. The damage by disasters notably droughts, floods and cyclones have caused various forms of vulnerability on populations living in disaster struck countries, including Zimbabwe. The natural disasters and catastrophes have inadvertently solicited for committed investment by both local and international governments to assist those unfortunate to have been struck by disasters and their impacts. Information on disaster impacts specifically related to food-aid distribution is gathered through an analysis of risks prevalent along the food and humanitarian aid supply chain network. This information will be used by government and various humanitarian stakeholders in the formulation of strategies to mitigate disaster and supply chain risks in humanitarian aid distribution. A mixed-method approach was employed to assess the impact of supply chain risk management in food-aid distribution in Zimbabwe. A sample size of 80 Humanitarian Aid stakeholders from the District Drought Relief Committee completed structured questionnaires. The Cronbach Alpha Test showed high reliability for the scales used in the study. Furthermore, the study used information from key informants, at least fifteen (15) members from the secretariat, namely, the District Administrators, the Social Welfare officers, as well as the Zimbabwe Republic Police (ZRP) personnel who were readily available at their stations for one-on-one interviews. Five strategies, that include flexibility, collaborative, prepositioning, hedging, and governance were explored and their impact on distribution of food-aid analysed. Quantitative data was analysed using STATA (version 16). Ordinary Least Squares (OLS) regression was used to investigate the nature and magnitude of the relationship between food-aid distribution efficiency and supply chain risk factors, while also controlling for the effect of demographic variables and results were compared with those of the Tobit models as a test for robustness of the results. Qualitative data was analysed using thematic analysis derived from observations and interviews and descriptive statistics presented in tables. This study tested the robustness of the five strategies used in food-aid distribution and noted that the most commonly used strategy is insurance, followed by governance, then collaboration, flexibility, prepositioning, and financing. SIGNIFICANCE OF THE STUDY It is expected that the study will assist the Government of Zimbabwe, other governments in Southern Africa, and humanitarian aid stakeholders in the formulation of policies for the humanitarian food and non-food-aid distribution. This will lead to improved efficiency in foodaid distribution. Policy recommendations highlight the need for synergistic relationships between WFP, the Meteorological Department, Department of Social Welfare, and the Civil Protection Department. The Government of Zimbabwe should therefore create an enabling environment for stakeholder partnerships in the Humanitarian Food -Aid supply chain that should cascade to the village and community levels. Disaster interventions should not only come from National Central Government but, where necessary and feasible, should be from local community to National, building a bottom up approach in disaster mitigation strategies.

    The assessment of disaster risk reduction strategies in dairy supply chains in Zimbabwe
    (2017) Chari, Felix; Ngcamu, Bethuel Sibongiseni
    Disasters are on the increase globally with devastating effects. The devastation caused by these disasters in various countries highlights the need for increased commitment and investment, by government and various stakeholders, in disaster risk reduction. This study investigated disaster risk reduction strategies in Zimbabwe’s dairy supply chains. The study was initiated on the premise that Zimbabwe is at high risk and vulnerable to natural and man-made hazards. The study is set in the backdrop of declining output across all agricultural sectors evident particularly in the dairy farming sector that has seen inadequate supply of raw milk and dairy products by local producers in Zimbabwe. This study therefore sought to assess the collaborative strategies by government, dairy organisations and dairy supply chain stakeholders to reduce disaster risks in the dairy industry. The study employed a mixed-method approach (qualitative and quantitative) to investigate collaborative disaster risk reduction strategies used by dairy supply chain stakeholders to avoid supply chain disruptions. The study used a sample size of 92 dairy farmers, from major milk producing regions of Zimbabwe, for the questionnaire. The Cronbach alpha test for reliability showed a reliable questionnaire. Furthermore, the study used information from key informants, 30 retailers and 20 dairy officers for one-on-one interviews. Quantitative data was analysed using STATA (version 13). OLS regression analysis was done and results were compared with those of the Tobit models as a test for robustness of the results. Qualitative data was analysed using thematic analysis derived from observations and interviews and descriptive statistics presented in tables and bar charts. Notable in the literature reviewed is lack of coordination amongst stakeholders in strategies to reduce disaster risks in dairy supply chains in Zimbabwe. This study adopted a collaborative proactive framework and tested it as a strategy to reduce disaster risks in dairy supply chains. The study gives four major findings. Firstly, dairy supply chains in Zimbabwe were exposed to a number of risks which are: international competition, competition from local giants, financial risks, political risks, technological risks, environmental risks and production risks. Secondly, findings from regression analysis indicated that an overall index of disaster risks significantly influenced job losses, food security, milk productivity and growth of ventures in dairy businesses. Thirdly, there were isolated cases of planned coordination by stakeholders in the industry to reduce the negative effects of disasters across the supply chain. There was collaboration among dairy farmers, processors, NGOs, and government departments of agriculture and environment. Fourthly, an index of collaborative strategies regressed against dependent variables of variables of supply chain cost, lead time milk sales, and variety and quality of milk demonstrated that collaborative strategies in dairy supply chain significantly influenced supply chain costs and variety and quality of milk and milk products. It is expected that the study will assist government in the formulation of public policies for the dairy sector leading to improved access to high quality raw milk and milk products for consumers thus resulting in improved nutrition and food security for the people of Zimbabwe. Policy recommendations highlight that instead of the current maximum of the 5 year lease given to white commercial farmers, the government should consider issuing out long term leases in order to protect long-term investment in dairy projects. Government should, therefore, create an enabling environment for stakeholder partnerships in the dairy sector.
