Urban sustainability: an inevitable aim of landscape irrigation’s

There is No Planet B. We must realize this sooner or later as the earth is being killed by the human in the name of Development. Throughout the world with 7 billion people on the planet – theoretically from today – there will be an inevitable increase in the demand on the world’s natural resources. Reckonings from the current rate of consumption mostly are under severe pressure.
Fresh, clean water is a limited resource. While most of the planet is covered in water, it is salt water that is unfit for human consumption. The contemporary water statistics indicates the highest water losses happen in traditional ways of irrigation where evaporative losses are high.
The principle of Sustainable development says that we must live within environmental limits. Landscape ecology has a high potential to contribute to sustainability in the interactions of people and nature. Over the years sustainable Landscaping has become a way of addressing many of the negative effects of development. Require less maintenance, reduce environmental harm, provide seasonal interest, use native plants, and encourage optimum utilization of resources especially water.
Irrigation of landscape does not only refer to watering of lawn/ garden/ landscape but it is all about adequately undertaking this operation so that we are not only able to satisfy the water demand of grasses, flowers, shrubs and trees but, at the same time able to generate aesthetic sense and ambient microclimate due to pleasing appearance (desired colour, shape, height : applicable for grasses and shrubs) of all the landscape components and adequately utilizing the water .
Harvel Irrigations Private Limited over the past 3 decades have delivered Lush green Landscapes of Akshardham Temple, Vrindavan Gardens and Lotus Temple to name a few as the best examples of effectively managed irrigation systems which have the following characteristics:
a) Delivers the desired amount of water to the grass which is neither so less that it causes water stress, nor so high that it causes waterlogging, with optimization of available resources such as water, energy, and labour.
b) Makes irrigation possible in odd hours when it is practically not possible for the gardener to irrigate the area manually.
Automation in irrigation refers to mechanizing the irrigation system through a series of valves, rotors, sprinklers, drip, and hoses by appropriately designing this system keeping in mind the water requirement of the flora of the landscape and available resources.
When we talk about Automation of irrigation in Landscape, we need to first look at the drivers responsible for it. The prime reasons because of which landscape irrigation should rapidly move towards automating the operations in the lawns and gardens are as follows:
Uniformity of discharge results in a better quality of the grasses, flowers, and shrubs.
Uniform Irrigation is also feasible on land with elevation difference.
Reduces dependency on labor.
Night irrigation is also possible.
Rain Sensors
Working of an Automated Irrigation System
Moisture sensors detect and guide the controllers about the ambient Temperature and Moisture requirement. The irrigation sensors detect the water level and indicate when it falls so that irrigation can be planned based on that. So, the sensors raise an alarm for the controllers to signal the irrigation which in turn help to calibrate the entire irrigation schedule through the solenoid valves. Through solenoid valves, Mainline, Sub mainline and Rotors and/ or emitters, water is delivered in the appropriate quantities in the area where it is desired. By way of this, water can also be delivered at night when it is not practically possible by manual means. In addition to this, these controllers followed by solenoid valves can also give us the liberty to automate the irrigation and Fertigation (optional) for longer periods of time like a week/ 10 days, etc.
“New developments in machine intelligence will make us far smarter as a result, for everyone on the planet and result in better utilization of resources.”/
