About

AquaCrop-OSPy is a python implementation of the popular crop-water model AquaCrop, built from the AquaCrop-OS source code.

AquaCrop-OS, an open source version of FAO’s multi-crop model, was released in August 2016 and is the result of collaboration between researchers at the University of Manchester, Water for Food Global Institute, U.N. Food and Agriculture Organization, and Imperial College London.

AquaCrop-OSPy has been designed in way that users can conduct cutting edge research with only basic python experience. In particular for the design and testing of irrigation stratgeies.

Open access journal article here

It is built upon the AquaCropOS crop-growth model written in Matlab ( paper , webpage ) which itself itself is based on the FAO AquaCrop model Webpage . Comparisons to both base models are shown here.

A forum has also been created so that users of AquaCrop-OSPy and AquaCrop-OS can discuss research, bugs and future development.

There is also an extensive documentation for the model

Install

pip install aquacrop

Quickstart

A number of tutorials has been created (more to be added in future) to help users jump straight in and run their first simulation. Run these tutorials instantly on Google Colab:

  1. Running an AquaCrop-OSPy model
  2. Estimation of irrigation water demands
  3. Optimisation of irrigation management strategies
  4. Projection of climate change impacts

AquaPlan

The latest development is a streamlit-based web application AquaPlan, a powerful crop management tool that enables farmers, businesses, and governments to make more informed decisions about water management, irrigation investments, and climate risks.

You can access AquaPlan using the following link: https://tinyurl.com/aquaplan.

More information, including screenshots and gifs, can be found at The University of Manchester's article, Tim Foster's medium post, or twitter thread.

A seperate category inside the AquaCrop-OSPy forum has been created to discuss AquaPlan, including any issues, questions, or suggestions.
