Plant Production on the Threshold of a New Century describes and compares problems and frontier developments in the different sectors of plant production, integrating developments in basic plant sciences, crop science and socioeconomic science, leading to sustainable plant production. Hence the book formulates goals and constraints in policy, economy, production, environment and land use; indicates how these goals and constraints may be translated into farming styles and cropping systems; and describes how the fundamental plant sciences can contribute to the implementation of such farming styles and cropping systems.

This book presents and discusses new directions in plant systems research to bridge knowledge from the gene to the plant, crop and agro-ecosystem levels and to assist in solving problems in production ecology and resource use by identifying and applying new research methods. Functional genomics, systems biology and ecophysiological modelling of crop growth and development provide powerful tools for identifying genes and genotypes of agronomic importance. Despite remarkable advances in basic knowledge of plant genes and gene networks, there has been relatively little impact on crop improvement from the application of genomics and recombinant-DNA technology. Novel directions in linking plant sciences to crop and systems research are needed to meet the growing demand for food in a sustainable way. The challenge is to produce more food on the limited available land through more efficient use of natural resources and external inputs. Genetics of plant performance are discussed using examples of Arabidopsis thaliana and food crops. The concept of 'crop system biology' is introduced. Within the theme 'physiology and genetics' traits and mechanisms to improve crop adaptation are discussed.Furthermore, various approaches in modelling G x E interactions and crop performance are presented.Some chapters are dedicated to the role of diversity in optimizing resource use and crop performance. An outlook and dialogue on future directions in plant system research challenges readers with contrasting opinions on the way forward concerning this critical issue for the future of food production.

Crop performance can be changed by modifying genetic traits of the plant through plant breeding or changing the crop environment through agronomic management practices. Integration of crop modelling into genetic and genomic researches can enhance the future position of crop physiology in ‘plant breeding by design’ (Yin, X.

The sequencing of genomes has been completed for an increasing number of crop species, and researchers have now succeeded in isolating and characterising many important QTLs/genes. High expectations from genomics, however, are waving back toward the recognition that crop physiology is also important for realistic improvement of crop productivity. Complex processes and networks along various hierarchical levels of crop growth and development can be thoroughly understood with the help of their mathematical description – modelling. The further practical application of these understandings also requires quantitative predictions. In order to better support design, engineering and breeding for new crops and cultivars for improving agricultural production under global warming and climate change, there is an increasing call for an interdisciplinary research approach, which combines modern genetics and genomics, traditional physiology and biochemistry, and advanced bioinformatics and modelling. Such an interdisciplinary approach has been practised in various research groups for many years. However, it does not seem to be fully covered in the format of book publications. We want to initiate a book project on crop systems biology - narrowing the gaps between genotypes and phenotypes and the gaps between crop modelling and genetics/genomics, for publication in 2013/2014. The book will be meant for those scientists and graduate students from fundamental plant biology and applied crop science who are interested in bridging the gap between these two fields. We have invited a group of scientists (who have very good track records in publishing excellent papers in this field or in a closely related area) to contribute chapters to this new book, and they have agreed to do so.

Children are both fascinated by, and afraid of, snakes and other reptiles, making them a receptive market for this topic. My first book of Southern African snakes and other reptiles introduces 56 different species, with accurate, full-colour illustrations accompanied by concise text and simple graphics that depict where the reptile lives, what it eats, how it reproduces, and how big it is when fully grown. In addition to snakes, the title also features lizards, geckos, skinks, tortoises and turtles - of all shapes and sizes, some dangerous and to be treated with caution, others harmless, some rare, and all part of the fragile chain of life. The clear text is geared for young readers (aged 3-8); parallel translations make this title suitable for mother-tongue learners in four official languages, as well as for older children and adults wanting to improve their knowledge of a second or third language.
