The proceeding of tropical agriculture is a proceeding of papers presented at the International Conference on Tropical Agriculture. Sustainability of agriculture production system is an important issue in the world, which includes all aspects of sustainable criteria, such as technical, socio-economic, and ecological aspects. This book covers sustainable tropical agriculture, sustainable tropical fisheries, sustainable tropical animal production, sustainable tropical forestry, tropical animal health, and Innovative and Emerging Food Technology and Management. The most common, challenging issues in plant, animal and fisheries production in the tropics are climate change, inefficiency production system, low technological innovation, decreasing environment quality, and the outbreak risk of pest and diseases. These issues are closely linked to the socio-economic condition of farmers as small-scale farms are dominant in this area. In addition, post-harvest technology is crucial to maintaining the high quality of products after on farm production. This volume provides the recent research and development on tropical agriculture production systems for plant, terrestrial animal and aquatic animal to establish sustainable agriculture production in the tropics.

From the pre-Columbian era to the present, native Amazonians have shaped the land around them, emphasizing utilization, conservation, and sustainability. These priorities stand in stark contrast to colonial and contemporary exploitation of Amazonia by outside interests. With essays from environmental scientists, botanists, and anthropologists, this volume explores the various effects of human development on Amazonia. The contributors argue that by protecting and drawing on local knowledge and values, further environmental ruin can be avoided.

Zeit ist ein rätselhaftes Phänomen. Woher kommt sie? Wohin geht sie? Wir haben" Zeit, spüren den Zahn der Zeit" - aber be-sitzen, beherrschen und festhalten können wir unsere (Lebens-) Zeit nicht. Selbst ihre Meßbarkeit in Minuten und Sekunden ist uns zwar vertraut - doch ist Zeit wirklich meßbar? Und wie hängen Zeit und Bewegung zusammen? Diese und viele andere Zeit-Fragen wurden bereits von zahlreichen Philosophen und Theologen durchdacht, u.a. auch von Augustin (Bekenntnisse"), Michael Ende (Momo"), dem Tü-bin-ger Theologen Eilert Herms (Meine Zeit in Gottes Hän-den") und dem Prediger" in der Bibel. Sie kommen in diesem Buch zu Wort - einzeln, in einem außergewöhnlichen Vergleich und mit kritischer Hinterfragung der Autorin -, um uns letztlich zu zeigen: Zeit ist noch viel rätselhafter, als sie scheint! Gabriele Berger-Faragó, 1973 in eine deutsch-ungarische Familie hineingeboren, studierte von 1994 bis 2001 in Heidelberg, Lexington (Kentucky, USA) und Stirling (Schottland) Anglistik, evangelische Theologie, Psychologie und Pädagogik. Die Autorin lebt mit ihrem Ehemann in Heidelberg und arbeitet seit ihrem 1. Staatsexamen in der Erwachsenenbildung. Parallel dazu bereitet sie sich in evangelischer Theologie auf das Kirchliche Examen der Badischen Landeskirche vor, um anschließend in den Pfarrdienst zu treten.
