It takes a week to travel the 8,000 miles overland from Java to Kotlin. If you're an experienced Java developer who has tried the Kotlin language, you were probably productive in about the same time.You'll have found that they do things differently in Kotlin, though. Nullability is important, collections are different, and classes are final by default. Kotlin is more functional, but what does that mean, and how should it change the way that you program? And what about all that Java code that you still have to support?Your tour guides Duncan and Nat first made the trip in 2015, and they've since helped many teams and individuals follow in their footsteps. Travel with them as they break the route down into legs like Optional to Nullable, Beans to Values, and Open to Sealed Classes. Each explains a key concept and then shows how to refactor production Java to idiomatic Kotlin, gradually and safely, while maintaining interoperability.The resulting code is simpler, more expressive, and easier to change. By the end of the journey, you'll be confident in refactoring Java to Kotlin, writing Kotlin from scratch, and managing a mixed language codebase as it evolves over time.

Peri-urban interfaces - the zones where urban and rural areas meet - suffer from the greatest problems to humans caused by rapid urbanization, including intense pressures on resources, slum formation, lack of adequate services such as water and sanitation, poor planning and degradation of farmland. These areas, home to hundreds of millions of people, face unique problems and need distinctive and innovative approaches and solutions.This book, authored by top researchers and practitioners, covers the full breadth and depth of the impacts of rapid urbanization on livelihoods, poverty and resources in the peri-urban zones in diverse African, Asian, Latin American and Caribbean contexts. Topics include peri-urban resource sustainability, ecosystems and societies and environmental changes in peri-urban zones. Rich case studies cover production systems and livelihoods including the impacts of irrigated vegetable production, horticulture, dairy enterprises, waste-fed fisheries and pastoral livelihoods. Also addressed are planning and development issues in the peri-urban interface including the difficulty in achieving sustainability, conflict and cooperation over resources, and a fresh look at the relationship between people and their environment. The final part of the book presents policies and strategies for promoting and measuring sustainability in peri-urban zones including community-based waste management, the co-management of watersheds and empowerment of the poor.This book is the most comprehensive examination of the challenges and solutions facing the people and environments of peri-urban zones and is essential reading for all practitioners, students and academics in geography and development.

The previous three volumes in the series on Caribbean geography explored how geographical and cognate research was being applied to address key environmental problems in the Caribbean. The present volume makes a further significant contribution to the literature. It highlights how current research is addressing rapid change in the Caribbean region, both that being forced by global warming and by population growth. The chapters are presented as a series of original, empirical research contributions, which have the common theme of the search for development strategies that focus on the social and economic needs of the people without further deterioration of the region's fragile environmental resource base. The articles have been selected to emphasize the importance of a multidisciplinary focus in this applied research field. Among the subject areas covered are climate change, sustainable food production systems, urban planning and community development, and coastal management. The authors conclude the volume by developing the critical research agenda on these and other issues.

This is the fifth in a series of volumes published by UWI Press exploring how geographical and cognate research is being applied to address key environmental problems in the Caribbean region. Global Change and the Caribbean highlights how current research is addressing the consequences of change, forced by global warming and climate change, and driven by globalization and population growth. The book takes forward issues of regional and community vulnerability, and focuses on the search for solutions in terms of adaptation, resilience and societal transformation.The question of transformation is debated by authors and the editors in drawing together the prospects for regional and community resilience. The chapters are presented as a series of original, empirical research contributions, which have the common theme of the search for development strategies which focus on social and economic needs of the people without further deterioration of the region’s fragile environmental resource base.The book will be essential reading at first degree and masters levels in institutions with Caribbean-focused courses relating to geography, and in multidisciplinary areas such as development studies, social studies, environmental management, planning and resource management. The approaches and case studies presented here will be of significant interest to regional planners, resource management specialists and public sector officials.
