Innovative Water Resource Management in Agriculture4 min read

Introduction

Water is the basic need of life and one of the core elements of sustainability of living beings on planet earth. We have learnt since our childhood that 70 percent of earth surface is covered by water. However, the dilemma is, this large mass of water is not fit for human consumption and agricultural purposes. We are only available with 1 percent of fresh water resources to fulfill our drinking and other farming needs. This situation demands wise and innovative water resource management in agriculture and other sectors of daily life.

Now, I want to divert the focus of my readers towards the population explosion aspect that we are facing for the past 2-3 decades. Population on the globe has increased at an exponential rate. There has been a dramatic escalation of population graph line if you plot years and population number on a graph as shown below.

The above graph is quite self-explanatory that how we are expanding. Within a century, we have added almost 5 billion people and in coming 2-3 decade, we will be around 9 billion. This fast phase population explosion is on the other hand exerting pressure on the limited resources of the earth. Similarly, food demand is on a high and it will get increase in future as we are adding more mouths to our food basket.  

Now when we link the water availability situation with population, a dark picture comes out as a result. As stated earlier, we are bestowed with only one 1 percent fresh water resources by nature and this resource is limited. On top of it, we are wasting water criminally in domestic and agricultural purposes, thus creating a difficult situation for our coming generations. Water resources are also facing another pressure from the changing climate. Changing rainfall and temperature patterns due to climate change are affecting negatively on water resources. So importance of innovative water resource management in agriculture increases many folds.

Widening Gap of Water Demand and Population

Over the years, because of the factors discussed in previous lines, per capital water availability of water has reduced. In some parts of the world, it has crossed the red line. There is a widening gap between the water demand and population as presented in graph below.

The reason for which I build the case so far is that the changing dynamics of water, climate and population needs new and innovative measures to tackle in order to have sustainability in all forms of life, especially in agriculture. Out of the box approach is needed to address all the issues.

What is Innovative Water Resource Management?

Innovative Water Resource Management is the set of management techniques that include cutting-edge knowledge and innovative approaches including an in-depth understanding of the inherent economic, scientific, social and environmental aspects to manage water resources for its sustainable consumption and to ensure the healthy recharge of water resources.

The advanced countries of the world are investing a great deal on planning and development of Innovative Water Resource Management techniques to ensure minimal water loses and enhanced water use efficiency.

The current trend of water use that is widely practiced in various parts of the world including Asia and Africa is the usage of water only once and then disposal. This trend is harmful and has created water scarce situation in many areas. Innovative Water Resource Management emphasizes more on reuse of available water through processing treatments.

Innovative Water Resource Management from Agriculture Perspective

Water lose in agriculture is lot more as compare to other sectors of the economy. Especially in third world countries, due to lack of technology, water is still used in traditional ways of irrigation in farming that results in excess loss. There are several innovative techniques now available globally to ensure water resource management in agriculture sector.

Though these technologies are expensive, however, their indigenized area specific versions have been developed, keeping in mind the local needs and budget. These are proven beneficial both for farmers and from water management perspective. Some of these Innovative Water Resource Management techniques included;

  1. Hydroponic system to grow vegetables on a media that is water use efficient.
