Hello everyone.
I am Joel Vicencio from Peru. I am developing the Land section, and I would like to incorporate import and export products. In Peru, rice and corn are the main crops that are imported since the domestic production does not cover the domestic demand (note that there is domestic production); while coffee and cocoa are the main crops that are exported once the domestic demand is covered. I would like to incorporate import and export in my BAU scenario, but I am not clear which parameters to modify.
I start by incorporating only rice. In rice, the national demand is 3328 ktn and the national production is 3190 ktn; therefore, the quantity to import would be 138 ktn. In that sense, I have only incorporated a new technology (IMPRIC) and in OutputActivityRatio I have set IMPRIC to 1.
I have followed the following route, but the end result is that all the rice is imported.
MINLND → (1) → LND → (1) → LNDRICHI and LNDRICHR → (847.03 and 422.74) → CRPRIC IMPRIC → (1) →
I would be very grateful if you could give me some advice on how to incorporate imports and exports. Thank you very much in advance.
Regards
Hi Joel,
I am going to base my response on the following understanding of your question: your import supply route is working (the problem is that you only get import) and you have previously confirmed that your domestic production supply route is also working (i.e. you had feasible solutions before adding the import option).
Osemosys/CLEWs optimizes on cost, so if you see results that are exclusively reliant on imports it means that the cost of imports is cheaper than domestic production with your current assumptions. As you don’t mention anything about costs in your question perhaps you have not have added any costs at all. To do this, use the variable cost parameter to set the import price for your crops. Keep in mind that you are unlikely to get the exact mix of imports and exports unless you have a detailed and carefully calibrated model. Alternatively you also have parameters that would help you constraint imports or domestic production to “force” values that match what you have from national statistics.
Best,
Tom
Hi Joel,
I thought I previously replied, but not sure if it sent! Further to Tom’s great advice above, please let me know if you need any further help.
Best, Kane.
