Water is essential for (human) life, as necessity and threat. With industrialization, water use has grown exponentially, notably in agriculture (irrigation). Withdrawal from open water and groundwater constitutes blue water use. Water in soils and vegetation is called green water; grey water refers to waste water flows. The complex stocks and flows of water can be related to human activity in the water footprint. Blue water use of surface and groundwater and its availability vary greatly across the globe. Many people live in water-stressed regions, due to groundwater depletion, little and/or irregular rain and declining quality due to pollution. Water is a prime example of a common pool resource (CPR), but increasing demand and subsequent scarcity have led to marketization and privatization of water provision and infrastructure.Because water use is intrinsically regional, water modelling and governance should be context-specific and participatory. The path to sustainable water use will have to address the divergent views on water as private or public good, and on ways to connect water engineering (including for hydropower) to practices less damaging for biodiversity (nature-based solutions).

Parts of Europe experienced from the seventeenth century a rapid growth in economic activity, in a combination of scientific discoveries and colonial conquest and exploitation. In a series of processes, some of them with medieval roots, populations and economic output (approximated in terms of monetary transactions) increased exponentially, first in Europe and its offshoots, then in the 20th century also elswhere. Humanity had entered the Anthropocene. Patterns of economic activity changed from agriculture to manufacturing, then to services. Trade connections multiplied in waves of globalization. Economic inequality within and between countries rose significantly during most of these centuries; it was greatly influenced by the rapid economic growth in China. The industrialization had great and harmful impacts on Nature, in the form of massive changes in landscapes and of pollution of air, water and soils. This is considered in detail in the chapters on food, water, energy and materials.

Chapter 1 provides an introdution to the study of statistics and covers the following specific topics among others: Statistical Software in Data Analysis, Descriptive and Inferential Statistics, Measurement of Variables, and an introduction to the Stata Software Package

Industrialization and the concomitant growth in populations and economic activity happened in parallel with changes in everyday life, both material (hygiene, diet, mobility) and immaterial (literacy, law, values and ideas about political order and human life). It is associated with Enlightenment, the emancipatory stream of Modernity. It meant changing roles and relations between the major institutions: (nation-)state, church and (community-)market. The outstanding hallmark was and is the idea of Progress, exemplified in the characteristics of the scientific worldview and its claim to ’objective Truth’. Another feature lies in the new ideas about good and evil, as propounded in Industrial Era ethics of liberalism and utilitarianism and in Enlightenment ethics.

What is sustainable development about? Development means an unfolding of the individual and the collective along the dimensions of body, mind and spirit. Sustainability refers to the capability to uphold and develop a certain desired situation. Sustainable development can thus be interpreted as the wish and capability to preserve the quality of (human) life and its unfoldment, in harmony with other living beings and within the terrestrial constraints. It represents ideals and aspirations. Key aspects are the way in which the collective organizes their realization through institutions, and on the basis of which views of Nature and of needs.

Chapter 11 covers INFERENCES INVOLVING THE MEAN WHEN σ IS NOT KNOWN: ONE- AND TWO-SAMPLE DESIGNS and includes the following specific topics, among others: t-Distribution, Degrees of Freedom, t-test assumptions, one-sample t-test, two-sample test for independent groups, two-sample test for related groups, paired-sample t-tests, effect size, the bootstrap, and power analysis.

The quest for sustainable development should build upon scientific knowledge - as the title of this book indicates. However, (scientific) knowledge is itself framed differently in different worldviews. The concept of complexity, and its increasing role in science, can assist in exploring some epistemological issues and approaches about the quality of (scientific) knowledge (post-normal and Mode-1 Mode-2 science, NUSAP) - important in times of ’alternative facts’. It also influences the scientific and engineering endeavour par excellence: (formal) modelling. In sustainability science, it shows up in intense efforts to complement natural science models with models that include (human) behaviour (next chapter). Communicating complexity happens also in less formal ways, with metamodels, analogues and metaphors, and organizing concepts (transition theory, social dilemmas and others).

The history of the concept of sustainable development shows early concerns on behalf of environmental NGOs and some religious people; later on, the voices of scientists, economists and businesses became (more) influential. The United Nations (UN) became a leading organizer and mediator. Gradually, the perception of the relationship between humans and Nature started to change, with important consequences for science and policy. The need for integrating the various aspects led to the emergence of Sustainability Science as a separate branch, and to the Sustainable Development Goals (SDGs) as an overarching framework for political actions and processes.
