Ecological intensification of
agricultural landscapes
Akker Naar Bos Congres – Bemmel, 9 December 2016
2. The intensification discourse
The world’s population will grow to 9 billion by
mid-century, putting substantial demands on the
planet’s food supply. To meet these growing
demands, we will need to grow almost twice as
much food by 2050 as we do today. And that
means we’ll need to use genetically modified
crops and other advanced technologies to
produce this additional food. It’s a race to feed
the world, and we had better get started.
By 2050:
• Population is expected to grow by 28%, from 7 to 9 billon
• Most of the growth expected in poorest regions (diets below average)
• About 3 to 4 billon people to eat better diets (mainly China and India)
• Food habits: plant based diet, less waste
• We have choices!
Where does the ‘doubling production’ discourse come from?

8. Sustainability
Hard targets vs. soft targets
How do we make such a soft concept operational?
Dimensions (Brundtland): social, environmental, economic
Indices: semi-quantitative assessments, scores, rankings
Indicators: principles, reference values, thresholds
The planetary
boundaries
Any form of agricultural intensification that contributes to trespassing
these boundaries, and/or that jeopardizes the ability of future
generations to feed themselves can be considered unsustainable

Recognizing that protoxins can be more potent than activated toxins against resistant
insects may help to enhance and sustain the efficacy of transgenic Bt crops.

Editor's Notes
Add potato mixtures yield
We found 5 different types of municipalities. These types are characterized by a certain set of ecosystem services.
There are 2 kinds of municipalities with cropland but one has more livestock and one with a higher concentration of horses. There are 2 types of municipalities with a lot of forest and forest products, but one of them has more moose hunting and higher nutrient retention. And the urban municipalities have a high concentration of recreational activities.
Now how closely municipalities fit the category they are in can reveal opportunities for the potential of the kinds of services they can produce.
