Sir Gordon Conway, an Ecologist from the Imperial College London well experienced in development policy, describes an environment with three key challenges for food security. Challenges for food production. 1. One billion people hungry in the world. 2. A necessity of increasing food production by 70 to 100%. 3. A world price-crisis that still now is causing problems for marginalized people in developing and developed countries. The higher demand for food is explained by a rising population, an increase in income of some countries with economic growth and energy policies (demand for bio-fuels). On the other hand, degraded lands, degraded water, impact of climate change is negatively affecting food production at a global scale. “Marginalized people are those who own less than 2 hectares of productive land, involving 400-500 million of smallholders, most of them in Asia and Africa.” Sir Gordon Conway, Key Note Speaker at Tropentag 2011. Multiplier effect of agriculture.

Looking back on the first day of Tropentag 2011 A ‘hub of discussion’, ‘the most important international conference for the development oriented scientific community’ or just a networking event… with more than 1000 participants from all over the world Tropentag is everything but boring. Looking back on the first day. ‘There are a billion people that are currently hungry. We’ve never had that number of hungry-stricken in the world before. If we’re going to feed the world by 2050 we need to increase food production by something as 70 to 100 percent. The food price spikes are going to recur and food prices will stay high.’ This statement of Sir Gordon Conway (Imperial College) during the plenary speeches on the first day of the Tropentag, will be leading during the whole conference in Bonn. These are the facts. How can research make a contribution to solve this problem? Questions As Claudia Mueller (University of Bonn) argued in the opening session of the Tropentag, research on ‘development of the margin’ is needed and should be a guiding principle for all researchers. ‘We will only be successful if we manage to improve the hunger situation for the marginalized in development.’ She raised questions such as how to balance development in favorable and marginal environments? Should marginalized people and communities become key players in an increasingly globalized resource use, and if so, how?

Prof. Sir Gordon Conway Gordon Conway is Professor of International Development in the Centre for Environmental Policy of the Imperial College of London and holds five honorary degrees and fellowships. Trained in agricultural ecology, he attended the universities of Bangor, Cambridge, West Indies (Trinidad) and California (Davis). In the 1960’s he was a pioneer of sustainable agriculture, developing integrated pest management programs for the State of Sabah in Malaysia. He joined Imperial College in 1970 setting up the Centre for Environmental Technology in 1976.
