I'm not sure exactly what you mean by "large scale agriculture"? I am very much am interested in increased agricultural output. But my feeling is that the many small holders in Africa really are the ones who need help to accomplish this instead of a large-scale industrial model of agriculture.

Something I did a while back was to start a wiki Ugandalinks. I'm not at all sure whether it's a useful thing or not. Christina Jordan was interested in collecting links at one point. I decided to give it a shot and made the wiki to do that. But it probably would have been better to make the list here at Ned. In any case you are most welcome to go to Ugandalinks. To see the pages there's a quickstart box on the right, click on the tab that says "sidebar" that will give a list of pages. I see that I made and agriculture page. LOL I haven't bee good about adding links I will add a few later today. You can edit the pages, make new pages, add links or text too. The password is ned4lia.

One Internet resource I like very much is African Agriculture. It's a blog that combs through news about agriculture in Africa and brings the stories together in one place.

Brosdi is an interesting model of using ICT to improve agriculture. They have a blog called Celac Collecting and Exchanging Local Agricultural Content.

In addition to improving agricultural output, I think it's very important to develop ways to add value to products; for example food processing is important. Some in LiA are looking into food drying.

There are so many challenges to face and so many complicated issues. I'm very interested to hear what you think.
