Assessment of opportunities for Burundian small-scale potato farmers to increase productivity and income

From 2014 through 2016, on-farm experiments were carried out in three provinces surrounding Bujumbura town in Burundi to improve the low potato (Solanum tuberosum) yields, which currently stand at about 6 t ha−1. It was hypothesised that in rain-fed conditions, improved varieties, healthier seed tubers, pre-sprouting in light, proper fertilisation and protection from late blight attack would improve yield and quality, such as tuber weight, tuber size and lower brown rot incidence. The treatments in the on-farm trials at five farms in each of three sites (15 replicates) were applied in two seasons, giving 30 replicates in 580 plots. The following treatments were compared with growers’ current practices: introduction of two new varieties, use of early generation seed from a rapid multiplication scheme, earlier harvesting of a seed crop, seed storage in a diffused light store, and research-based timing and dose rate of fertilisers and fungicides. Marginal rates of return on investments were calculated at farm level and current and tested alternative technologies were compared. Costs and benefits of applying such techniques were calculated. An improved variety contributed up to 20% yield increase and healthier seed 80%. Early harvesting reduced yield by 30% and reduced incidence of brown rot in the current season, but increased it (from 21 to 39%) in the following season when tubers were replanted. Diffused light storage, alternating contact and systemic fungicide application, and application of chemical fertilisers resulted in 30, 50 and 60% yield increases, respectively. It was shown that it is possible to double yields and economic returns (marginal rates of return) under the growing conditions in Burundi when growers plant healthy pre-sprouted seed of a new variety and apply chemical fertilisers and fungicides.The Netherlands NWO Knowledge for Food Program, Applied Research Fund.http://link.springer.com/journal/115402019-03-01hj2018Plant Production and Soil Scienc

Major incident simulation in Rwanda: A report of two exercises

Introduction: Healthcare systems must be equipped to handle major incidents. Few have been described in the African setting, including in Rwanda. The purpose of this case report was to describe and discuss two major incident simulations in Rwanda with different challenges. Case report: We report two recent major incident exercises conducted in Rwanda, in 2017. The exercises exemplify two different types of multiple casualty incidents requiring the deployment of extra-ordinary resources, one due to the location of the incident (off-shore), and the other due to the large volume of casualties. Both exercises required extensive multi-agency planning and training beforehand, as part of an increasing awareness of the need for preparedness for these types of incidents. Conclusion: The exercises demonstrated the need for a standardised, physiological method of triage based on clinical needs; this is in order to maximise the number of lives saved. Triage training should be an integral part of further major incident exercises, which should be conducted regularly. Keywords: Major incidents, Triage, Rwand
