Dr. Martin Hamer, chief executive officer of the International Centre for Sustainable Development, holds a master degree in agricultural sciences and a PhD degree in soil sciences, where he investigated the transfer of pollutants from the soil into water, crops and the food chain respectively. After his PhD he received a scholarship from the German Research Foundation (DFG) and worked several years in the area of environmental sciences at the University of California in Riverside (USA) and at the Institute of Crop Science and Resource Conservation of the University of Bonn (Germany). From 2005 to 2014 he established and headed an interdisciplinary and cross-border research network in food and agricultural sciences. During that time he coordinated several national and international projects in the area of food quality and safety, environmental risk management and sustainable agriculture focussing on the interaction between food production and environmental. Furthermore he supported different stakeholders in agrofood chains and research bodies by facilitating international co-operation, distribution of project results, and knowledge transfer. Thus he is skilled in the field of adult education and an experienced EU-project manager.

KLUGER Transfer - Climate - Environment - Health - Transfer

The project's aim is to develop and test new methods and instruments for institutionalised transfer cooperation between non-university research institutions (AUF) and universities of applied sciences (HAW), using the example of global climate and environmental change and associated health effects. A multi-stage transfer chain from basic research via applied research and teaching to societal, economic, and political actors will be developed. Suitable and innovative formats will be designed and implemented to create a sustainable system of knowledge transfer into practice. Accompanying research will record and analyse knowledge transfer preferences of researchers and practitioners.

One Health - A holistic approach to metropolitan regions Part 2

Using the One Health approach, the research college, led by ZEF at the University of Bonn, is looking at urban food systems: on the one hand, at the "supply of healthy food from sustainable production" and, on the other hand, at the "spread and transmission of antibiotic-resistant pathogens" through food chains. Furthermore, health-related aspects of urban transformation are highlighted, which fall into the areas of "health and well-being" and "sustainable cities".

Livestock Strategy

The aim of the project is to establish a structure that is sustainable in the long term and meets the requirements of animal welfare and environmental justice, as well as the business and social needs of livestock farms. Due to the consequences for the livestock farming industry, a broad dialog is required. This is to be worked out in the further course of a dialog process with agriculture, including the upstream and downstream economy, environmental and animal welfare associations as well as the food retail trade and consumer associations.

ProciNut - Production and Processing of Edible Insects for Improved Nutrition

The project intends to better exploit the potential of edible insects for nutrition. It explores different processing technologies of local insect species and expands small-scale commercial production and processing activities. The goal is to produce safe and nutritious end products that fill seasonal gaps, increase household food security, and improve the income situation of poor women in Madagascar and Myanmar. The network coordinator is the Center for Development Research ZEF at the University of Bonn.

Campus to World

Bonn-Rhein-Sieg University of Applied Sciences has adapted its existing transfer instruments to the changing demands and requirements of business and needs of business, society and science and developed new suitable transfer mechanisms. The project was funded by the federal-state initiative "Innovative University".

Roiporq - Alternative husbandry systems for more sustainability in pork production

In the project "Roiporq - Suitability of a special pig cross-breeding for alternative forms of husbandry with full physical integrity of the animals for differentiation in the market" a special pig cross-breeding, which is suitable for conventional and organic fattening, will be tested for market suitability. The meat of this cross-breeding should be sensorially distinguishable for consumers and thus be recognizably differentiated from conventionally produced pork.

Less food loss in fruit, vegetables and potatoes between the field and the store counter

In addition to the losses of fresh fruit and vegetables that occur within households, the losses that occur at the beginning of the value chain play a major role. If food is not used as such, the resources used for production (e.g. labor, land, energy, fertilizer and pesticides) and the environmental impacts of production (e.g. greenhouse gases, nitrate leaching) are not matched by corresponding benefits. Therefore, a reduction of losses is also important from an environmental point of view.
