Wednesday 18 October: Use of drones in agriculture and rural development - Part 1

Wednesday 18 October: Use of drones in agriculture and rural development - Part 1

Today (part 1) and tomorrow (part 2) we will be looking at how  drones are used in agriculture and rural development in a more thematic way. For example, how can drones help when cultivating crops? When are they useful? When can we use them to monitor pests or diseases? In which ways can drones contribute to precision agriculture. We identified some of the interesting articles and use cases in the use of drones in these specific areas:

  1. Soil and field analysis: Drones produce precise 3-D maps for soil analysis for farmers to decide where to plant but also for soil analysis after planting, providing data for irrigation and nitrogen-level management.
  2. Crop monitoring: Drones provide time-series animations which can show the precise development of a crop and reveal production inefficiencies.
  3. Input management: Drones can scan the ground and spray the correct amount of liquid for the plants to grow or drone-planting systems can shoot pods with seeds and plant nutrients into the soil.
  4. Crop and livestock health: Drones can detect when a crop is low on water or minerals but can also detect diseases and prevent them from spreading.
  5. Crop insurance: Drones are used to assess damage to crops after disasters or bad weather.
  6. Rural advisory services: Drones can be used to improve rural advisory services by combining several ways of making information available to farmers.
  7. Biodiversity and conservation: Dronse can be used to monitor biodiversity and to support conservation efforts, such as protecting animals from illegal poachers.
  8. Land mapping: Drones can be used for the mapping of land and this can be very important for example for farmers in developing countries to claim land properties. More on this topic will be shared on Monday 23 October with contributions from the University of Twente.
  9. Early warning, disaster risk reduction and resilience: Drones are used frequently for early warning and response to crisis in the humanitarian context. A few examples are brought forward here and you will be able to learn more about drones in humanitarian action on Friday 27 of October.  
  10. Fishery: Drones are used to track illegal fishing
  11. Forestry: Drones are also used to monitor forests. More about drones in forestry on Friday 20 October with FAO Panama

Drones can give more detailed information than satellites on crops, including accurate production statistics, onset of diseases and pest infestations and the effects of climate change. https://cipotato.org/press-room/blog/cip-drone-study-over-sweetpotato-fields-of-east-africa-a-success/ or https://cipotato.org/press-room/blog/invasion-of-the-potato-drones/ 

News: Maize breeders reaping benefits of using drones

The International Maize and Wheat Improvement Center (CIMMYT) in Southern Africa has adopted UAVs to collect data as a critical part of successful breeding programme. http://www.scidev.net/sub-saharan-africa/farming/news/maize-breeders-reaping-benefits-of-using-drones.html

Article: Why drones are valuable tools for plant breeders

This article presents the potential of drones for plant breeders who have to monitor a wide large amount of different varieties of the same plant. Plant breeders need to check the different varieties very regularly and this is extremely time consuming. By using drones and multi-spectral images they can save a lot of time and detect mature and immature plants based on changes in the light frequency they reflected. The efficiency of using drones is especially important for African farmers as they have to find new breeds of maize and wheat that are more resistant to the climate changes they are currently experiencing. https://drone-dossier.com/tag/farmdrones/
