Lack of Standardization

The lack of universally accepted standards among developers of IoT systems in water management presents challenges in aligning and integrating tools offered by different vendors.

Innovative Solutions for Water Scarcity Through IoT

With seventy percent of our planet covered in water, one might find this fact reassuring and question the need to prioritize such an abundant resource. However, it’s time to reconsider. The reality is that water scarcity is becoming an increasingly pressing issue. Reports suggest that by 2025, around 20% of the world’s population will feel its impact. 

• Moreover, by 2040, approximately one in every four children worldwide will live in areas facing severe water shortages. 
• This challenge is not limited to developing nations alone. Freshwater, crucial for drinking, hygiene, agriculture, and cooking, is incredibly scarce. 
• Only 3% of the Earth’s water is freshwater, and a significant portion of that, about two-thirds, is either locked in icy glaciers or inaccessible for our use.

Effects of Water Shortage

1. Numerous non-governmental organizations report that approximately 1.1 billion individuals globally lack access to clean water, while a staggering 2.7 billion people experience water scarcity for at least one month annually. While climate change and population growth are major contributors, they are not the sole factors. 
2. Human-induced issues such as deteriorating infrastructure, disrupted distribution systems, pollution, conflicts, strained water systems, and inadequate water resource management are increasingly depriving individuals of their fundamental rights to safe water and sanitation.
3. During periods of water shortage, malfunctioning sewage systems can heighten the risk of diseases like cholera, typhoid fever, and other water-related illnesses. This global crisis is significantly impacting ecosystems worldwide. Furthermore, the rising cost of water indirectly affects the economies of nations.
