The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

"The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

This book examines the evolution of the phenomenon and explores the genesis of overtourism and the system dynamics underlining it. The 'overtourism' phenomenon is defined as the excessive growth of visitors leading to overcrowding and the consequential suffering of residents, due to temporary and often seasonal tourism peaks, that lead to permanent changes in lifestyles, amenities and well- being. Enormous tensions in overtourism affected destinations have driven the intensification of policy making and scholarly attention toward seeking antidotes to an issue that is considered paradoxical and problematic. Moving beyond the 'top 10 things you can do about overtourism', this book examines the evolution of the phenomenon and explores the genesis of overtourism as well as the system dynamics underpinning it. With a rigorous scientific approach, the book uses systems-thinking and contemporary paradigms around sustainable development, resilience planning and degrowth; while considering global economic, socio-political, environmental discourses. Researchers, analysts, policy makers and industry stakeholders working within tourism as well as those within the private sector, community groups, civil society groups and NGOs will find this book an essential source of information.
