Air-borne remote sensing as a monitoring tool for smallholder's cropping systems in East Africa

633 views

Published on

To achieve sustainable food and nutritional security while maintaining or reducing financial and environmental costs, smallholder farmers need to be supported by high-tech systems. Low-cost but robust sensors mounted on unmanned aerial vehicles (UAV) along with open source software constitute emerging solutions. To this end, a “proof of concept” is under investigation in Eastern Africa. A workshop held in Nairobi resulted in the establishment of a community of practice on agricultural UAVs in East Africa. First field mission was conducted in Tanzania. Field work has yet to take place in Kenya and Uganda once flight permits are issued. Salient advantages of small Unmanned Aerial Systems (sUAS), preliminary results and bottlenecks will be outlined in this presentation.

  7. 7. Workshop objectives How can ARSIS become part of the tools that improve agriculture and the wellbeing of smallholder farmers? Specific Objectives: 1) Learn what ARSIS means to each participants’ practice: core developers, application scientists, end users & enablers 2) Identify networks of collaboration for the community of practice in each country/region 3) Plan next steps

  10. 10. Highlights of messages from the meeting • Identified needs at smallholder farms: crop area statistics, Yield assessment, Variety discrimination, Early disease detection, Soil erosion and fertility assessment and Irrigation performance • Costs, accessibility, and user-friendliness matters • Involving local institutions at different stages is a must • Walk the talk – e.g. test in making official statistics • Complementarity with satellite imageries • Stepwise – From simple to complex tools

  19. 19. Applications for flight permits Country Purpose Date of process initiation Applicatio n date Response date Observation Kenya Test the newly assembled UAV 21/01/2015 27 January UAVs are on ban in the country until regulatory framework released Tanzania One week field mission 27/01/2015 5 March 27 March Mission completed Uganda One week field mission 27/01/2015 5 Nov. Mission planned in December Rwanda 1 hour demonstration in a conference 27/7/2015 21 Sept. 28 Sept. Mission completed The most critical issue is to know from where to start the application
  20. 20. WAY FORWARD • Planning and implementing joint work with STARS Project • Second workshop to take place in Mwanza, Tanzania (March 2016) mainly focused on advances in the theory of change: – translational research to provide information in the context of the decision makers – identifying impact pathways, and – Defining strategies for overcoming barriers related to regulatory frameworks
