PrefaceDear Delegates,We extend a very warm welcome to all the delegates attending the conference Deut-scher Tropentag 2003 to be held at the Georg-August-Universitt Gttingen in Octo-ber 2003. A very special welcome to all young scientists and students from overseasand elsewhere. Please be our guests.The Deutscher Tropentag 2003 is the 5th annual meeting, which was preceded byconferences organized by the Humboldt Universitt Berlin (1999), University of Ho-henheim (2000), University of Bonn (2001) and University of Kassel-Witzenhausen(2002) in cooperation with the Association for Tropical and Subtropical AgriculturalResearch (ATSAF). The theme of the conference is Technological and InstitutionalInnovations for Sustainable Rural Development where research experiences on foodsecurity, natural resource management and rural development will be shared and dis-cussed. This year we are overwhelmed by the large number of submitted contribu-tions. This has been a challenge to the scientic committee and often decisions weredifcult to make. We are proud seeing the Deutscher Tropentag to be recognized asan international event on the agenda of the scientic community and decision makers.The programme and proceedings are published on number of plenary sessions has been increased this year. There are four parallelsessions on the rst and second day, and plenary sessions on the rst and third day. Intotal, we have 16 thematic sessions and three plenary sessions. Each session beginswith an invited paper and is followed by three oral presentations and several shortposter presentations. Please appreciate the posters, which are on display throughoutthe conference. Please take your time and have a look. There are a couple of opendiscussion fora and meetings of associations taking place as well. Last but not least,we invite you to socialize at our conference dinner on Thursday evening.We wish you interesting sessions, valuable discussions, and please use the opportunityto meet people from different backgrounds. We hope that you will enjoy the three-dayevent and leave exhausted, but enriched. To help us to improve the conference in thefuture we would like to receive your feedback. 3 4. We would like to thank all the DTT team members, who contributed to the planningand organization of the conference. The local organizing committee receives specialthanks for having prepared this meeting. Last but not least we acknowledge the spon-sors for their generous and essential support.We wish you all a successful and enjoyable event and a safe journey back. We hopeto meet all of you again at Deutscher Tropentag 2003, to be organized by HumboldtUniversitt zu Berlin.Gttingen, 8th October 2003Gode Gravenhorst, Director Clemens Wollny,Centre for Tropical and SubtropicalOrganizing and ScienticAgriculture and Forestry (CeTSAF)Committee DTT 2003Georg-August-Universitt Gttingen Georg-August-Universitt Gttingen4 5.

Deutscher Tropentag 2003 Georg-August-Universitt, GttingenInstitutional Innovation, and Investment in Rural Public Goods for Development and Reduction of Poverty J OACHIM VON B RAUNInternational Food Policy Research Institute (IFPRI), UnitedThe institutional and political context within which the rural economy operates haschanged rapidly in the past two decades. The agriculture and food system is changingfrom a relatively large and distinct economic sector to a more pervasive, system inte-grated within the global economy. In order to improve equity and efciency, nationalgovernments must provide public goods, including internal peace, rule of law, andpublic investment in education, health, nutrition, and infrastructure. But a massivescaling-up of investment in enhancing productivity in rural areas of developing coun-tries is needed, as well. The fast trend toward inequity has to be reversed because it isinefcient, unfair, and risky for societies.Keywords: Developing countries, institutional innovation, public goodContact Address: Joachim von Braun, International Food Policy Research Institute (IFPRI), Washing- ton, United, e-mail: j.von-braun@cgiar.org8 9.

R EGE2 1 International Livestock Research Institute (ILRI), Director General, Kenya 2 International Livestock Research Institute (ILRI), Animal Genetic Resources Group, KenyaTo alleviate world poverty and environmental degradation, a new approach to agri-cultural research is needed. The conventional research model moving from basicto strategic to applied and adaptive research - whose products are then taken up byextension staff and disseminated, fails to address the complex local circumstancesand realities of farmers and other private and public stakeholders. The new research-for-development model that is emerging focuses on enhancing the adaptive capacityof research providers and farming communities alike for problem-solving capabil-ity on the move. It incorporates into the research/innovation process participatoryapproaches, multi-scale analysis and intervention, systems analysis and informationmanagement and impact assessment. Being more socially accountable than traditionalresearch models, the process involves many partnerships engaging users throughoutin order to identify research needs, mobilise resources, conduct the research and eval-uate the outcomes.The Africa based International Livestock Research Institute (ILRI) and its many part-ners conduct research at the intersection of livestock and poverty. Keeping livestockhelps half a billion poor people in developing countries to secure assets, and thus pro-vides a pathway out of poverty. This paper examines ILRIs strategic response to thechanging environment in which international research is being carried out. Focal re-search areas and paradigms are both changing. ILRI has reorganised its research intove interlinked themes to implement a revised strategy that emphasises innovationsystems, participatory research, a strengthened social science capacity, partnershipsand interdisciplinary teamwork.ILRI is committing itself to a socially distributed knowledge system, where research isconducted always within the context of application and with the imperative of poverty-alleviating knowledge products present from the start of the innovation process. Toproduce a stream of innovative, creative, demand-driven and competitive knowledgeproducts has required that ILRI reorients its culture from traditional supply-drivendisciplinary science to demand-driven community-based transdisciplinary scienticapplications.Keywords: Research themes, research-for-development model, transdisciplinary sci-entic applicationsContact Address: J.
