14. Rainwater Harvesting and Current Advancements

Our natural resources such as water, soil, forests, etc. are limited. As the cities are burdened with new residential areas, industries, food supplies with increasing population, the demand for these resources have been elevated as per they are already being exploited beyond their limits. Water is the basis of our life as crucially involved in simple chores of drinking, cooking to high scale industrial set ups. But with increasing urbanization and industrialization the water bodies have been exhausted to their utmost limit. Which is why there is a need to develop the alternate water sources. For this, the concept of rainwater harvesting comes up as a robust approach for sustaining the human needs. Rainwater harvesting is not a new policy; only it has been revitalized with the modern scientific approaches since there is numerous evidence of ancient civilizations of conserving and harvesting rainwater. The common method involves rainwater harvesting is a collection of rainwater in different structures and then making use of it in daily life, conserving it for future applications or it recharges the groundwater bodies. The implementation of varying rainwater harvesting techniques and methods varies from place to place depending upon their specific climatic conditions, land topography, hydrogeological conditions, etc. Also, it strengthens the relationship between the humans and the environment, making them aware of the need for conserving nature and natural resources along with sustainable development.
