Science is a fundamental for social and economic progress in developing is a body of knowledge that represents current understanding of natural systems and the process whereby that body of knowledge has been established and is continually extended, refined, and revised. Both elements are essential: one cannot make progress in science without an understanding of both. Likewise, in learning science one must come to understand both the body of knowledge and the process by which this knowledge is established, extended, refined, and revised (Duschl, Schweingruber, & Shouse, 2007, p. 26). A developing country is a nation with a less developed industrial base meaning that there is room for improvements that will make it a better place. Namibia is still a developing country due to income inequality. This paper serve to discuss the role of science in developing countries. According to Karen Worth, the goal of science is to understand the natural world through a process known as scientific inquiry. Science help learners to explore the physics of water and have an open door to environmental topics. Science can guide technological development to serve our needs and interests. Science teaches an understanding of natural phenomena. It aims to stimulate a child’s curiosity in finding out why things happen in the way they do. Many environmental issues, such as water pollution, energy conservation and global climate change are grounded in physical science.
Science can contribute to the resolution of conflicts, such as those between water development and species preservation, by elucidating the role of hydrologic processes in the behavior of the environmental and social systems in conflict, by defining the pivotal role that physical integrity of the hydrologic system plays in optimum management, and by providing an effective perspective for decision-making through de-emphasis of commodity-based approaches and emphasis on holistic concepts and processes.
Climate modeling is an evolving science, and varying degrees of reliability characterize the forecasts of future change that are derived from climate models. As noted above, the most reliable predictions are for continued warming in the present century causing less snowpack and earlier runoff. The prognosis that there will be greater variability in precipitation leading to more floods and droughts is also highly reliable, and it is predicted with some confidence that rainfall will increase at higher latitudes and decline in the subtropical regions. However, accurate estimates of changes in the amount of precipitation in different regions and in different locales within regions are more difficult to forecast. The science of climate change forecasting is evolving and should become more reliable with further research.
Science play a role in forming a successful solution to the world’s emerging water problems. In the broadest sense, there are two distinct ways in which science needs to be used. First, there is significant existing scientific information that could be helpful in solving contemporary and anticipated problems, but it is not being used. The scientific underpinnings that justify the use of holistic, integrated ways of managing the water resources of a basin are strong and well known.
Science help adapt technology to local circumstances. Even when technologies are imported from abroad, research is necessary to make them work. Rather than insisting on developing indigenous technologies, when abundant and well-proven technologies exist, scientists can help choose the right ones, given the local environment and available raw materials, and learn how to use them. Incorporate new science into education. Development requires a well-trained work force; therefore, high-quality education must be put in place early in development. The teaching of modern science in engineering or medical schools cannot be restricted to the same old classical textbooks but has to be done by active scientists who read the current literature and are capable of conveying the latest advances to their students. Science and scientists are an important element in choices and decisions made by governments and can make a difference. And science can accelerate progress. Science and scientists can play an important role in determining those choices and implementing development strategies.
