1. Keynote 1 - Precision Agriculture for Smallholders : Imperatives for Africa’s AgricultureThe African continent is at the dawn of the Fourth Industrial Revolution (4IR) with significant challenges around inclusivity. The concept of the 4-IR will imply the deployment of technologies at unprecedented scale at a time when sustainable production underscores the need to produce twice as much with half the resources. For Africa, Precision Agriculture (PA) as a modern technology, represents a sustainable approach that will help farmers to manage their resources and increase product... Y. Akinbamijo |
2. Keynote 2 - Satellite Earth Observations and Machine Learning for Agricultural Monitoring in Sub-Saharan AfricaFood security is one of the most pressing issues faced by many African countries today. 2019 brought further shocks and setbacks to crop production across Africa. Farmers in East Africa, for example, faced more devastating floods, the most severe (and still ongoing) desert locust infestation in 70 years, and of course the COVID-19 pandemic, which has affected every sector and every food sys...

3. Keynote 3 - Setting the Record Straight on Precision Agriculture AdoptionAdoption of precision agriculture (PA) around the world has been uneven. Some PA technologies have been the most rapidly adopted agricultural technologies in history and others have lagged. Among the disappointments is variable rate fertilizer, which was among the first PA technologies, but has become standard practice only for some farming niches. PA is a tool box – Farmers take the tools that they need and leave the rest. For example, in countries with mechaniz... J. Lowenberg-deboer |
4. Precision fertilizer management for soil fertility improvement in Sub-Sahara AfricaAttainment of food security remains one of the biggest challenges facing sub Saharan Africa. The continent continues to experience low production as a result of the low and declining soil fertility and land degradation, which have been compounded by unfavorable climatic conditions. Since the 1960s, there have been effort to transform the agricultural sector through promotion of diverse approaches of soil nutrient management. Research has demonstrated the potential and importance of fertilizer... A. Bationo |
5. Keynote 6 - Farmer-led design and knowledge sharing: Empowering smallholders to maximize impactProducers Direct is an international non-profit led by smallholder farmers for smallholder farmers. With over a decade of experience in farmer-led design and experimentation, Producers Direct has piloted and scaled a number of in-person and digital solutions that have improved the livelihoods for over 1 million small-scale farmers across East Africa and Latin America to-date. International recognition for our work has included UK Google Impact Challenge winner; World Bank Collaborative D... C. Rhodes |
6. Keynote 8 - Precision Agriculture in Sub- Africa: The Path ForwardSmallholder farmers contribute significantly to food security and rural livelihoods in Africa, but their yields are often low due to declining soil fertility, high input costs, and decreased availability of land for cultivation among other factors. These challenges are exacerbated by climate change. Furthermore, soil physicochemical and biological properties are heterogeneous among farms within same or different agro-ecological zones, with obvious consequences for yields. This variabili... K.

7. Imagining Precision Farming in AfricaAfrica needs its own and unique Green Revolution now, but it can also take advantage of many lessons learned all over the world. Precision farming is much more than the application of advanced, expensive technologies for managing soils and crops on a commercial scale. In the African context, it is all about better agronomy at any scale, including small and medium-size farms. Many ingredients for that exist already, whereas others still need to find their way into scalable business soluti... A. Dobermann |
8. Decision Aids: Mobile Apps and SensorsProducers are challenged daily with decisions. With the advancement in technologies the access to decision aid tools is becoming more wide spread. This decussion covers a few of the easily to use and apply technologies available. ... B. Arnall |
9. Mapping African soils at 30m resolution - iSDAsoil - Western Time Zones“iSDAsoil” combines remote sensing data and other geospatial information with carefully stratified point samples subjected to spectral analysis and traditional wet chemistry reference analysis. State of the art machine learning techniques were used to create digital maps of 17 agronomically important soil properties at 3 depths, including estimates of uncertainty. iSDAsoil is designed to encourage sharing and we hope that the owners of other soil and agronomic data, in i...

10. On-farm experimentation. A major role for precision agriculture in African agricultureIs precision agriculture relevant to African Ag? Most people envision fancy technology when they consider precision agriculture (PA). Indeed, over the past 30 years or more PA has introduced a range of exciting technologies to agriculture. But the real change is not the technology itself, but the new ways technology enables farmers to manage complex and uncertain systems. This message dates back to the early days of PA but has been superseded by technological prowess and needs to be... S. Cook |

12. Lime and Phosphorus Effects on Soil Acidity and Malt Barley Phosphorus Use Efficiency in Welmera District, Central Highlands of EthiopiaIn Ethiopia, about 43% of total arable land affected by soil acidity. Furthermore, phosphorus (P) deficiency is a major constraint to increase crop yields. Efforts to ameliorate the deleterious effects of soil acidity must therefore be accompanied by measures to increase P availability in soils. Therefore, appropriate rate of lime and P fertilizer is an important strategy for improving crop growth in acidic soils. Accordingly, an experiment was undertaken to study lime and P effects on soil a... N.T. Geremew, B.B. Waraka, L.W. Mirkena |
13. Agronomic Yield Response of Lowland Rice Varieties to Nutrient Application Under Flooded Irrigation in Northern UgandaGlobally, flooded irrigation is a major water management method used to boost rice production. In Uganda, flooded irrigation is being promoted for lowland rice farming amidst the increasing threat of climate change and variability. Use of mineral fertilizer and improved varieties during the rice cropping calender is a measure towards intensive and precision farming for increased yields. However, the response of lowland rice varieties to fertilization with a defined cropping calendar remain no... R. Akena, P. Musinguzi |
14. Fine-tuning Specialty Fertilization Strategies to Local Wheat Production Through On-farm Experimentation in NigeriaWheat specialty fertilizer validation trial was conducted in 8 Local Government Areas (LGAs) of Kano State, Nigeria on farmers field. The specialty fertilizer validation project is implemented to improve the productivity and profitability of small-scale wheat smallholder farmers. Four treatments - absolute control (AC), local control (LC), OCP1 and OCP2 were replicated four times in a RCBD on a plot of 25m2. The AC was based on the indigenous nutrient supply from the soil (no appli... V. Aduramigba-modupe, J.M. Jibrin, . Olabanji, B. Lawan, D. Madukwe |
