I am preparing my dissertation paper for the title proposal. I am needing 50 related kinds of literature in the field of university extension programs for sustainable development.
You could access UN and SDGs and country profile or south-south cooperation to view governments, International institutions/NGOs how approach, solve and contribute to global issues
You can check the program we have at El Colegio de Veracruz, if that is your main interest, I mean, searching for programs, we have bachellor, master and Doctoral degrees.

However, if you want some comparative methodology, you can check my review paper:
Sustainable livelihoods: An analysis of the methodology
Article Sustainable livelihoods: An analysis of the methodology
Ma Rovie Chavez These may help you. The first one is a very good comprehensive literature on sustainable development and in the second one, you can find list of many publications related to the subject matter.
With regards to profiling SUC extension, it really depends on your focus. You may start deciding on what theoretical lens would you like to use in examining extension activities/programs. In fact there may be many and you may select from it. You can refer to the aacup evaluation tool guide for extension.
