Weather and climate have been participating in an imperative function in both the expansion and crumple of mankind civilizations diagonally across the globe ever since the prehistoric eras. The Neolithic Mehrgarh (ca. 7000–2500 BC) and Balochistan and Indus Valley civilizations (ca. 2500–1500 BC), in Sindh Province in Pakistan, have been the spotlight of explorations to historians, anthropologists, and archeologists in terms of their origin, development, and collapse. However, very rare consideration has been given previously to the role of weather and climate, sanitation, and wastewater technologies in highlighting the lessons of these formerly well-developed ancient metropolitan civilizations. This study presents an existing climate of the archaeological sites, sanitation, and wastewater technologies to recognize the different elements that influenced the evolution of the civilization mystery. In addition, it is recommended that the weather and climate conditions in southwest Asia were the foremost controlling element in resolving the destiny of the Indus and Mehrgarh civilizations. Furthermore, the rural tradition was mostly adapted by the increasing rate of western depressions (winter rains), as well as monsoon precipitation in the region. The factors that affected the climate of both civilizations with the passage of time might be population growth, resource conflicts, technological advancement, industrial revolution, Aryan invasion, deforestation, migration, disasters, and sociocultural advancement. The communities residing in both civilizations had well developed agriculture, sanitation, water management, wells, baths, toilets, dockyards, and waterlogging systems and were the master of the water art.

Water-driven music technology has been one of the primary sources of human leisure from prehistoric times up until the present. Water powered, along with air pressure organs, have been used throughout history. One of them was an organ of fountains located inside a formal garden. Throughout ancient mythology, several different gods have been linked to music in many civilizations, in particular, Minoa, Mehrgarh, and Gandhara. Water deities were usually significant amid civilizations located next to a sea or an ocean, or even a great river like the Indus River in Pakistan, the Nile River in the Middle East or the Ganga River in India. These fountains performed a wide range of songs from Classical to contemporary Arabic, and even included other worldly music. The study of water-driven music technology demonstrates the diachronic evolution and the revelation that ancient people had impressive knowledge of the engineering needed for water exploitation and manipulation. This revelation is still both fascinating and intriguing for today’s water engineers. This paper also shows the relationship between water in nature and music, and furthermore, how nature has inspired composers throughout history. This research shows the sustainability of different kinds of water-driven musical instruments, not only through their use in past centuries, but their relevance in music therapy and other purposes of today. This study is useful for researchers in the fields of history, music, engineering and sustainable development. Full article
