Regulatory options to improve seed systems for vegetatively propagated crops in developing countries
In many developing countries, smallholder farmers cultivating vegetatively propagated crops (VPCs) have limited access to quality planting material. This constraint can limit both the yield of and returns on VPC cultivation. Yet policy and regulatory initiatives designed to strengthen access to quality VPC planting materials have been relatively unsuccessful to date. Part of the problem is the unique biological and economic characteristics of vegetative propagation and its distinctness from cereal crops, which dominate narratives on seed system reforms. Drawing on qualitative analysis of policy and practice, this study examines reform options related to quality assurance regulations in four ...

Congenital Heart Diseases: The Broken Heart
This book provides comprehensive insights into congenital heart disease from embryonic development through to clinical features, including human genetics and our current knowledge of the underlying molecular pathways. It is divided into three parts: an introduction to the development of the heart and its vessels, an overview of the molecular pathways affecting the development of various cardiovascular structures, and a main section focusing on the different types of structural and nonstructural congenital heart diseases, including their clinical features, underlying genetic alterations and related animal models and pathways. Taken together these chapters, which were written by and for clinicians and researchers, provide an integrated and cutting-edge resource for all those who want to learn more about both the clinical aspects and the genetic and molecular basis of congenital heart disease.
Trees and Forests of Tropical Asia
"Exploring the Tapovan takes the reader on an expedition into the leafy, clammy, forested landscapes of tropical Asia. Peter Ashton and David Lee, two of the world's leading scholars on Asian tropical rain forests reveal the geology and climate that have produced these unique forests, the diversity of species that inhabit them, and the role of humans in modifying the landscapes over centuries. This work follows Peter Ashton's massive On the Forests of Tropical Asia, the first book to describe the forests of the entire tropical Asian region, from Sind to New Guinea. It provides a more condensed, accessible, and updated overview of tropical Asian forests aimed at students as well as tropical forest biologists, ecologists, and conservation biologists"--
The Potato Crop
This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compare...
