I have experience working on the ground in Kenya and Nigeria. I have a stake in a farm in Uganda. The first thing we would do is subsidize soil sampling, because when you sample soils and get soil analysis done, you help small landholders understand where the constraints are in their nutrient balance in the soil.
The second thing you would do is encourage policies that encourage genetic engineering because, in many cases, the ability of us to engineer drought-tolerant and saline-tolerant crops in many of those areas is absolutely essential. We would also encourage the utilization of technology to increase pest resistance.
You can't feed the population of tomorrow on yesterday's technology. Canada is a leader in technology adoption. I think one of our primary exports as a country should be the agricultural technology that we have in our heads.
