Ecuador shrimp supply chain v1.0.0 (2013-2019)

This database describes the subnational production and international trade of Ecuadorian-produced shrimp, based on using a model called 'SEI-PCS Ecuador shrimp v1.0.0'.
For all shrimp exports from Ecuador, our model determines the likely parish in which the shrimp was produced, using trade and production data, sustainability certification records and information on company-specific assets. We used a decision tree to allocate exports either directly to shrimp production ponds, or to shrimp processing and packing facilities, by matching company names and asset ownership records. For exports without a direct link to shrimp production ponds, we then used linear programming to link the processing/packing facilities to the parishes where shrimp are farmed. We also used linear programming as a final step to allocate the remaining exports that we could not match with facilities or ponds to a parish of production.
