Rainwater harvesting is the accumulation and deposition of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places the water collected is redirected to a deep pit such as well, shaft, or borehole, a reservoir with percolation, or collected from dew or fog with nets or other tools. The text Rainwater Harvesting & Soil Water Conservation Technique presents the recent advances in water harvesting and also focuses on soil water conservation technique. There are always strong links between measures for soil conservation and measures for water conservation, and this applies equally in semi-arid areas. The objective of first chapter is to propose an estimation through which users can select a rainwater harvesting system for non-drinking water consumption. The goal of second chapter is to present an approach for designing garden variants that can be safely supplied with harvested rainwater, taking into account climate change and adaptation measures. Third chapter aims at assessing the impacts of climate change on rainwater harvesting systems (RWH) in the tropical urban city, Colombo, Sri Lanka. Fourth chapter investigates the benefit from a network of sharing RWHSs introducing different characteristics in water demand. Dimensionless analysis for designing domestic rainwater harvesting systems at the regional level in northern Taiwan has been focused in fifth chapter. The purpose of sixth chapter is to develop a set of universal definitions for potential domestic rainwater harvesting (DRWH) that can be used to quantify rainwater as a new obtainable water resource at national/regional levels. Seventh chapter investigates the performance of RWHS in peri-urban regions of Greater Sydney, Australia. Water vapor, temperature and wind profiles within maize canopy under in-field rainwater harvesting with wide and narrow runoff strips have been described in eighth chapter. Improved sustainability of water supply options in areas with arsenic-impacted groundwater has been discussed in ninth chapter. In tenth chapter, we propose an innovative method to move from the impact of RWH at the building level to larger and more complex scales. Eleventh chapter deals with future prospects for macro rainwater harvesting (RWH) technique in north east Iraq. The aim of twelfth chapter is to examine the interconnection between spatiotemporal distribution of the conducted cloud likelihood maps and clouds underneath terrain features to improve potential rainwater harvesting in the study area. The purpose of thirteenth chapter is to study how to increase rainwater consumption without discouraging farming. The role of weed and cover crops on soil and water conservation in a tropical region has been proposed in fourteenth chapter. Effects of soil and water conservation measures on groundwater levels and recharge have been investigated in fifteenth chapter. Alternative management practices for water conservation in dryland farming have been described in sixteenth chapter. In last chapter, we aim to corroborate the importance of sustainable land management (SLM) measures for Cape Verde, the strategies undertaken to address desertification, and the impact of those measures on the environment and rural livelihood.
