ASSIGNMENT HELP ON ECONOMIC ANALYSIS OF RAINWATER HARVESTING METHODOLOGY IN URBAN AREAS FOR DEVELOPED VS DEVELOPING COUNTRY

Abstract 

In this review, the potential of harvesting rainwater, especially in urban areas and agriculture is studied. The system configuration, modelling and economic analysis is performed and the researched in compared for two countries, Australia (developed country) and India (developing country). We see a lot of developing countries harvesting rainwater in urban areas to contribute towards cultivating food and agriculture. This trend is now being followed by developed nations like Australia because of the increasing prices of food and meeting demands. Rainwater harvesting (RWH) has been domestically used from rooftops when integrated with the house water management system, however these uses are only ideal for in-house use such as toilet, flushing, washing etc. but not food and agricultural purposes. There must be enough rainfall and water supply to promote the urban agriculture and this is what this research focus on. To properly understand the economic implications of RWH in urban areas, five step criteria is adopted. This review also highlights the absence of initiatives to utilize RHW. Later, a comparison is made between developed and developing countries which helps us understand the political, cultural and economic difficulties. Conclusions are later drawn regarding the choice of crops, water consumption rates and the different methods.

Background Introduction

Water scarcity is one of the biggest problems in this world currently, especially with the developing nations. It is found that there is a considerable potential to supply water to urban agriculture using customised roof Rainwater harvesting (RWH) system designs. Rainwater harvesting in urban areas means storing the water which is first harvested from a roof area and then stored in a tank for later use in either household or irrigation. Further generally it is defined as, “a method of inducing, collecting, storing, and conserving local surface runoff for subsequent use” (Rahman, 2017). It is agreed that there is a greater need for water supply for green sustainable cities, in this research the greater question is raised which is to what degree can we maximize the use of rain water and encourage RWH in urban areas. Also the broader question is what are the how does it affect for a developing or a developed country (Amos, Rahman et al. 2018).
