"This book employs a qualitative approach to dissect contemporary legal debates surrounding sustainability, efficiency, and efficacy in government systems, with a particular focus on Zimbabwes constitutional democracy. An effective legal framework, characterized by robust laws that promote sustainability and enhance the efficiency of governmental systems, is, the book argues, essential for the success of a nation. Exploring sustainable development as a multifaceted initiative aimed at advancing economic and socio-political well-being, the book delves into the concept of good governance, defined by the accountable exercise of power, transparent government selection, and the efficient management of resources. Within Zimbabwes legal framework, where all laws, practices, and conduct are subject to constitutional validation, the book underscores the obligatory nature of constitutional duties for individuals, the State, and all executive, legislative, and judicial bodies. Positing that sustainable resource management, underpinned by equitable and unbiased legislation, is essential for Zimbabwes long-term prosperity, the book demonstrates how effective legal frameworks can drive national success. The book will be of interest to researchers in the field of sustainability, environmental law and governance"-- Provided by publisher.
