In the heart of northern Ghana, where the rhythm of life is dictated by the rains, a new tool is revolutionizing the way smallholder farmers approach their livelihoods. The DROP app, a hydroclimate information service, is bridging the gap between scientific weather forecasts and local, indigenous knowledge, offering a unique blend of data that could reshape agricultural practices and potentially impact the energy sector.
Developed by Samuel Jonson Sutanto of the Earth Systems and Global Change Group at Wageningen University and Research in the Netherlands, the DROP app provides both local rainfall forecasts (LF) and scientific rainfall forecasts (SF), along with soil moisture forecasts. This hybrid approach aims to deliver actionable knowledge for climate-smart farm decision-making, a critical need in regions where agriculture is predominantly rainfed.
The app’s local forecasts, derived from indigenous knowledge, have shown a high probability of rain detection, with a minimum value of 0.7. When combined with scientific forecasts, the hybrid forecast (HF) yields an impressive probability of detection (POD) of 0.9. However, the hybrid system also comes with a higher number of false alarms, which slightly diminishes its overall performance compared to scientific forecasts alone.
Despite this, the impact on farming practices has been significant. Farmers using the DROP app have adjusted their activities, from the time of sowing and planting to the application of fertilizers and herbicides, and even harvesting. “The DROP app has given us a new way to plan our farming activities,” said one farmer. “We can now make more informed decisions based on reliable forecasts, which has improved our yields and reduced our risks.”
The potential commercial impacts of this technology are vast, particularly for the energy sector. Agriculture is a significant consumer of energy, from the production of fertilizers to the operation of irrigation systems. By optimizing farming practices, the DROP app could lead to more efficient use of resources, reducing the energy footprint of agriculture. Moreover, as climate change continues to affect weather patterns, the need for accurate and actionable weather information will only grow. The DROP app’s ability to integrate local knowledge with scientific data could set a new standard for weather forecasting in agriculture.
The research, published in the journal Heliyon, highlights the potential of the DROP app to facilitate effective agriculture management. As Sutanto notes, “The DROP app is not just about providing forecasts; it’s about empowering farmers with the knowledge they need to adapt to a changing climate.” This empowerment could lead to more resilient agricultural systems, better prepared to face the challenges of the future.
The future of the DROP app and similar technologies lies in their ability to adapt and evolve with the needs of farmers and the changing climate. As more data becomes available and as machine learning algorithms improve, these tools could become even more accurate and reliable. This could lead to a new era of precision agriculture, where every drop of rain and every grain of soil is optimized for maximum yield and sustainability.
The DROP app is more than just a tool; it’s a testament to the power of collaboration between science and local knowledge. As we look to the future, it’s clear that technologies like the DROP app will play a crucial role in shaping the way we approach agriculture and, by extension, our energy needs. The journey of the DROP app is just beginning, and its potential to transform agriculture and the energy sector is immense.
