In India, where there are cities struggling to provide even basic amenities to their tax-paying citizens, a village in Gujarat—Punsari—is equipped with modern amenities like CCTV cameras, WiFi and a renewable energy power station.

The key to achieve strong, durable concrete rests with the correct ratio for mixing cement and water. In the process, there are many methods employed for concrete curing, and one of them is using gunny bags and sprinkling water. However, this method ends up consuming a lot of water, and is also labour-intensive, as the curing requires round-the-clock monitoring or the effort goes down the drain.
In India, water scarcity is a known subject. But there are a very few examples when it comes to tackling the same. We all know that water from waste sources like kitchen, bathroom, etc. goes straight to the drainage areas and gets submerged to either a river or coastal water, further polluting it. However, a village in Haryana has set an example by creating dry drainage where used water from bathrooms and kitchens goes straight to a covered pit.

But a team of scientist from the Department of Aerodynamics in Bengaluru has come out with an idea to restore forestland by using drones and seed bombs saving number of hours of manual intervention.
It is a sad fact that every 3 minutes an Indian girl is sold into sex slavery. The average age of these girls is 12. Ironically, only 1% of them are ever rescued. The road to rehabilitation, if she is rescued, is extremely difficult. Yet, there are very few NGOs working to prevent this from happening, and one of them is My Choices Foundation.
