Data Analysis Methods for Crop Pre-Harvest Planning

Excited to share my latest geospatial analysis on coffee land suitability in Bukoba Rural, Kagera - one of Tanzania’s key coffee-growing regions ☕🌍 Using R and geospatial data, I developed a multi-criteria suitability model integrating NDVI, rainfall, temperature, and elevation to map areas with the highest potential for sustainable coffee production. This workflow demonstrates how data-driven spatial analysis can support smarter agricultural planning and climate-informed decision making. This work was inspired by Markos Budusa Ware (Ph.D.), whose research approach motivated me to explore advanced suitability modeling and apply it to my own area of interest. I hope this analysis encourages researchers, GIS specialists, and agricultural planners to leverage open tools and satellite data to improve land management and crop suitability assessments. There is huge potential for collaborative research in geospatial agriculture across Africa. #GIS #RemoteSensing #CoffeeFarming #LandSuitability #GeospatialAnalysis #RStats #Agriculture #ClimateSmartAgriculture #GlobalCoffeeTrade

What if your #crops could tell you their #yield weeks before harvest? That’s no longer science fiction — it’s #AI + #Drone-powered yield prediction. Here’s how it works technically--> *Step 1 – #Crop #Identification Every crop has a spectral fingerprint. AI models (CNNs, SVMs) classify the crop type from multispectral data. *Step 2 – #Weed & #Disease #Filtering Not all green is crop. Models like YOLOv8-seg, U-Net, Mask R-CNN, Detectron2 remove weeds and stressed plants. *Step 3 – #Feature #Extraction Drones measure growth parameters: • Plant height (DSM – DTM difference) • Canopy cover & Leaf Area Index (NDVI, EVI, SAVI) • Flowering patterns from imagery *Step 4 – #Yield #Prediction with #AI This is where algorithms step in: --Random Forest Regressor – Many decision trees voting → robust & reliable. --XGBoost – Sequentially improves predictions by fixing errors → very accurate. --LightGBM – A faster, scalable version of XGBoost → perfect for massive drone datasets. Together, they can forecast yield within ±5% accuracy weeks before harvest. Why it matters: --Farmers can plan inputs & sales. --Buyers can optimize pricing & logistics. --Governments can estimate food supply & security. Yield prediction isn’t guesswork anymore. It’s #data → #AI → #decisions.

This applies, among others, to basil downy mildew 🌿 and grey mould on grapes 🍇. It is a key element in assessing the risk of diseases in crops. 📚 More and more producers are aware that the absence of disease symptoms does not mean there is no threat. And in predicting them, 𝐝𝐢𝐬𝐞𝐚𝐬𝐞 𝐟𝐨𝐫𝐞𝐜𝐚𝐬𝐭𝐢𝐧𝐠 𝐦𝐨𝐝𝐞𝐥𝐬 using weather data play an increasingly important role, allowing growers to anticipate infection risk even in seemingly healthy plants. 📚 A grower can easily create their own disease forecasting model for their crops. The most important elements are 𝐝𝐚𝐭𝐚 𝐜𝐨𝐥𝐥𝐞𝐜𝐭𝐢𝐨𝐧, 𝐛𝐚𝐬𝐢𝐜 𝐛𝐢𝐨𝐥𝐨𝐠𝐢𝐜𝐚𝐥 𝐤𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞, 𝐰𝐞𝐚𝐭𝐡𝐞𝐫 𝐝𝐚𝐭𝐚 and simple tools such as Excel. In the case of pests or treatment optimization, photoperiod (growing degree days / GDD) is also important. 📚 Additionally, 𝐭𝐫𝐚𝐩𝐬 (sticky, pheromone or light traps) can serve to confirm the model: the model forecasts, the trap confirms, so the grower knows it's time to intervene. 📚 There are many benefits to data analysis, but the most important include: 🎯 𝐏𝐫𝐞𝐜𝐢𝐬𝐞 𝐭𝐫𝐞𝐚𝐭𝐦𝐞𝐧𝐭 planning 📉 𝐑𝐞𝐝𝐮𝐜𝐭𝐢𝐨𝐧 𝐨𝐟 𝐜𝐨𝐬𝐭𝐬 and amount of plant protection products 🌱 𝐈𝐧𝐜𝐫𝐞𝐚𝐬𝐞𝐝 𝐞𝐟𝐟𝐞𝐜𝐭𝐢𝐯𝐞𝐧𝐞𝐬𝐬 of biological methods 🧠 𝐑𝐢𝐬𝐤 𝐦𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭 instead of reactive approaches A grower can develop their own model for forecasting infections and pest occurrences based on observations and simple weather-based rules. Such a tool supports decision-making for preventive treatments and helps determine the optimal timing of their implementation, especially in 𝐨𝐫𝐠𝐚𝐧𝐢𝐜 𝐚𝐧𝐝 𝐬𝐮𝐬𝐭𝐚𝐢𝐧𝐚𝐛𝐥𝐞 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧. This is one of the pillars of IPM: plant protection based on forecasting, observation, and action optimization. I encourage producers to create their 𝐨𝐰𝐧 𝐈𝐏𝐌 𝐦𝐨𝐝𝐞𝐥𝐬.

🌱📍 Spatial Risk Modeling for Maize: A Foundation for Precision Agriculture This work presents a spatial maize risk model built entirely on open, global geospatial datasets, designed to support early-stage agricultural planning and crop suitability assessments. The model follows a clear and transparent logic: key environmental variables are first translated into agronomic risk scores (1–10) based on maize-specific thresholds, and then combined using a weighted multi-criteria approach to reflect their relative influence on crop performance. 🌦️ Climate conditions (seasonal rainfall from CHIRPS and maximum temperature from ERA5) define water and heat stress, 🌱 soil quality is represented through soil organic carbon from SoilGrids, 🗺️ terrain limitations are captured using slope derived from SRTM, and 🚫 land-use constraints are applied using ESA WorldCover to exclude unsuitable areas. The result is both a continuous risk surface and decision-oriented risk classes (unsuitable, low, moderate, high), enabling intuitive interpretation and spatial comparison. 🌍 Because the model relies on globally available data, it can be rapidly applied to any region of interest worldwide with minimal adaptation—making it a strong foundation for digital twins, climate-risk analysis, and precision agriculture workflows. While powerful as a screening tool, its value can be further enhanced by integrating local climate observations, soil surveys, management practices, and crop phenology in later stages. 🚜📊 Scalable, transparent, and actionable—this is where data-driven agriculture begins. // ----------------------------- FINAL MAIZE RISK INDEX (1–10) // ----------------------------- var maizeRisk = climateRisk.multiply(0.35)  .add(soilRisk.multiply(0.30))  .add(slopeRisk.multiply(0.15))  .add(landUseRisk.multiply(0.20))  .rename('maize_risk'); maizeRisk = maizeRisk.where(worldcover.eq(10), 9); #Portfolio #PabloAngulo #PrecisionAgriculture #DigitalAgriculture #AgTech #CropSuitability #ClimateRisk #GeospatialAnalytics #EarthEngine #Maize #SustainableAgriculture #GEE
