 I think there's two things. One is we can learn from the history of experience. Many of the problems we're experiencing today are problems that have been experienced in the past. We should learn from that. For example, I mentioned rubber. We have large companies going back to plantation rubber again. It doesn't make any sense from a historical perspective. The second reason is that a lot of what we see in terms of commodity production around the world and its patterns is traced to decisions that were made about land and labor rights in the past. So I gave examples of how oil palm, for example, shifted to Southeast Asia as a result of land policies in West Africa. So it helps us understand how and where products are being produced now. I think the rubber story is interesting in that. It was a wild species. It was harvested wild. And then when you had the automobile industry take off around 1900, you had this huge demand for rubber. So you're looking for opportunities to make it into a cultivated product to be able to meet the supply. And there was a huge amount of experimentation done by many different companies and different species to try to convert rubber from a wild to a cultivated species. And the current species, which is Javier brasiliensis, was actually the one that the Malaysian colonial government and planters were experimenting with. And that's the one that worked. And so having plantations with deep pockets with the capital, the time and capital to experiment I think was important in that happening. But once you had the technology worked out, there was no reason that plantations had any comparative advantage in rubber production because it's a very labor intensive crop. You have to go out and harvest it every day. It was ideally suited to smallholders. So when the colonial governments turned around around 1930, they said, oh, there's all these smallholders out there. They just hadn't expected, they hadn't counted on it. In fact, their policies have been hostile to smallholder rubber production. And then they just took it over. So you had this sort of progression. And I think there is a role for private capital in overcoming some of these pioneering risk in establishing a new crop in a new area. Oil palm is a little bit different because you have to coordinate the harvesting very closely with the processing and the processing is very large scale. But I think that's the problem that can relatively easily be overcome, particularly if you have organized smallholders or you have a very dense network of mills like you have now in Sumatra in Indonesia. So I anticipate that oil palm is going to work very quickly towards more smallholder fraction. And particularly as the larger companies having problems accessing land and so on, they can solve a lot of those problems by outsourcing to smallholders just the same way as bananas were outsourced in Central America. I think it relates very much to the certification question. I think this horticulture, you started off with standards. First of all, there were food safety standards for Europeans, very high minimum standards. And then you had social and environmental standards on top of that. And they get more and more rigid over time. It was more and more difficult to get smallholders to comply with those standards. So in certain horticultural commodities there's been a move towards larger scale. What kind of commodities do you horticulture? My other one that I was looking at recently was beans in Kenya, for example. It seems like that's been moved back to when small scale and then it's been moved back to more medium scale or some large scale. In terms of what I was looking at, I was impressed with what the progress in labor standards consistently over a century. I was impressed at how quickly in terms of the environmental standards on deforestation we seemed to be moving. We didn't start on that until the 1990s and we seemed to be moving in a historical point of view very rapidly. But land is still land rights of people affected by large scale investments. That's still a work in progress. And we don't have an international organization that champions their rights. And I think there's a long way to go to establish some sort of minimum standards on land rights.
