“…where T denotes time; S T is the storage in the cistern; x T is the rainfall inflow; R T is the water withdrawal (consumption) dependent on the annual demand D and a T is a set of 12 coefficients periodically varying with time (Figure 6a); and K is the storage capacity, here assumed 20 m 3 [43]. An example of the average monthly function of one cistern's storage volume with an annual demand of D = 36 m 3 is presented in Figure 6b.…”

Modern Use of Traditional Rainwater Harvesting Practices: An Assessment of Cisterns’ Water Supply Potential in West Mani, Greece

Water has always been a driver of human civilization. The first human civilizations thrived in places with an abundance of water, typically nearby large rivers as the Tigris–Euphrates, Yang Che and Nile. The invention and construction of hydraulic infrastructure came only later, in prehistoric times, triggered by the expansion of humanity in water-scarce areas. The ancient Greeks invented impressive hydraulic works and small-scale structures, some of which, such as cisterns, were still fully operational until the 20th century. We present a model that explains the use of cisterns in the water-scarce area of West Mani, which allows us to assess the potential of this traditional rainfall harvesting practice to support the modern water supply needs. To assess the system’s reliability, we employ a long-term simulation of a typical cistern system, using synthetic rainfall series from a stochastic model, and assuming variable water demand on a monthly scale. We show that a proper restoration of the cisterns could be sustainable as a complementary water supply source, decreasing the area’s drinking water cost and increasing the locals’ resilience against water shortages. In addition, we highlight the links between the area’s hydroclimate and its history and discuss the cultural merits of reviving and preserving this ancient, long practice.

The modern globalized civilization is sustained by interactions, trade, the transportation of goods, and energy. Energy self-sufficiency is crucial in rural and disaster-prone areas like North Euboea because dependence on external energy supplies can leave regions vulnerable to supply chain disruptions, price volatility, and geopolitical risks. In such isolated regions, energy independence ensures resilience in natural disasters and economic instability. The alternative to self-sufficiency often involves reliance on centralized energy systems, fossil fuels, or external imports, which may not always be reliable or sustainable. Therefore, in this study, we explore the possibility of an area having energy self-sufficiency. As a case study, we chose North Euboea in Greece, explicitly focusing on the Municipality of Mantoudi-Limni-Agia Anna. The analysis combines local land use patterns, energy needs for inhabitants, agriculture and water requirements. It is followed by exploring various renewable energy sources, including hydropower, biomass, solar, and wind. We considered the stochastic nature of renewable energy production and the challenges associated with energy storage. The findings suggest that while wind turbines and solar panels could be installed in the area and contribute significantly to energy needs, achieving complete self-sufficiency requires careful planning, particularly regarding energy storage and the social acceptance of these installations. The results highlight the need for a holistic approach that integrates environmental, landscape, societal, and technical considerations in designing and implementing renewable energy systems. Additionally, it is highlighted that the available renewable energy from forest biomass (before the 2021 megafire event) could reliably and adequately meet the area's energy needs without requiring investments in photovoltaic parks and wind turbines and without competing with the use of agricultural land.

Environmental determinism is often used to explain past social collapses and to predict the future of modern human societies. We assess the availability of natural resources and the resulting carrying capacity (a basic concept of environmental determinism) through a toy model based on Hurst–Kolmogorov dynamics. We also highlight the role of social cohesion, and we evaluate it from an entropic viewpoint. Furthermore, we make the case that, when it comes to the demise of civilizations, while environmental influences may be in the mix, social dynamics is the main driver behind their decline and eventual collapse. We examine several prehistorical and historical cases of civilization collapse, the most characteristic being that of the Minoan civilization, whose disappearance c. 1100 BC has fostered several causative hypotheses. In general, we note that these hypotheses are based on catastrophic environmental causes, which nevertheless occurred a few hundred years before the collapse of Minoans. Specifically, around 1500 BC, Minoans managed to overpass many environmental adversities. As we have not found justified reasons based on the environmental determinism for when the collapse occurred (around 1100 BC), we hypothesize a possible transformation of the Minoans’ social structure as the cause of the collapse.
