Climate Intelligence for Wine Farm Industry of South Africa ML Tool # ET-Geo-hackathon Climate Intelligence for Wine Farm Industry of South Africa ML Tool # VineVisualizers Irrigation Decision Pipeline A block-by-block, day-by-day irrigation decision tool for Tokara vineyard (Stellenbosch, South Africa), built on the FAO-56 evapotranspiration framework. Given weather, satellite, and phenology data, the pipeline tells a grower, for every block, every day: is it Green / Amber / Red, how many millimetres to irrigate if so, and how likely it is to need water in the next **N** days. This fills a gap that a monthly regional forecast ("Climate Compass") can't: daily, block-level, prescriptive guidance. --- ## Table of contents - 1. What this pipeline does - 2. Glossary - 3.

What this pipeline does Every vineyard block needs a certain amount of water each day. We estimate how much water the vine **should** be using (based on weather and growth stage) and compare that to how much it's **actually** using (measured by satellite). Adding in rainfall lets us keep a running tally of how "thirsty" the soil is, for every block, every day. From that tally, the pipeline answers three questions per block, per day: 1. Is it **Green** (fine), **Amber** (watch it), or **Red** (irrigate now)? 2. If Red, how many **millimetres** of water should it get? 3. How likely is it to need water in the **next N days**? --- ## 2. Glossary | Term | In plain terms | |---|---| | **Block** | One numbered/lettered section of vineyard (e.g. K1, R2). Tracked separately. | | **ETc** (crop water demand) | How much water a vine theoretically needs on a given day \u2014 its water "budget" for the day. | | **ETo** (reference evapotranspiration) | A standard weather-driven measure of the "evaporating power of the day," in millimetres. Doesn't depend on the crop or imagery. | | **E …
