Is there any way to connect two sectors in LEAP through a common constraint ? For eg. If I am modelling growth of Transport and Agriculture sector in a country. And I want to put a constrain on Area, i.e. for future, the area under Transport and Agriculture will increase (according to the estimated growth rates for the respective sectors) but under the constrain of total area of the country?

Please help.

Hi Anjali,

Certainly - LEAP provides a very flexible modeling framework, which you could use to implement a number of constraints. There are a number of ways you could do this, though I'll describe one suggestion here.

For any activity level that is shared between two different sectors, I would suggest creating a Key Assumption to represent total activity (area, in your question), which you can then reference in the Activity Level variable of each sector. You may find LEAP's 'Constrain' function useful, described here:

http://www.energycommunity.org/WebHelpPro/Expressions/Constrain.htm

...which you could use to ensure that the sum of activity levels across each sector is no greater than the value given by your Key Assumption.

Hope this helps!
