Maharashtra approves Nanaji Deshmukh Krishi Sanjivani Yojna to promote climate-resilient agriculture

Maharashtra Government has approved Nanaji Deshmukh Krishi Sanjivani Yojna, a Rs.4,000-crore project aimed at promoting climate-resilient agriculture. It will be roll out in 2018-19 and continue till 2023-24.

The Scheme has been named after social activist Nanaji Deshmukh who has worked in fields of education, health, and rural self-reliance, and has been honoured with Padma Vibhushan.

The scheme will be implemented in 5,142 villages across 15 districts. Its objectives are to improve soil quality, develop foodgrain varieties which can sustain climate variations and effect necessary changes in the crop pattern as per the availability of water in a particular region.

Main objectives of scheme

  • Promote very idea of sustainable development in agricultural sector.
  • Eliminate the problems of ground water salinity problems.
  • Improve conditions of the agricultural yields to overcome the climatic changes.
  • Promoting the quality of the soil such that quality of food grains produced can be improved.
  • Cultivate new variety of grains that will more sustainable and adaptable to climatic changes.

The scheme will cover small- and medium- scale farmers, who are more vulnerable to the impact of climate change. The total cost of project is Rs 4,000 crore, 70% of which will be borne by World Bank while state will contribute 30% over six years

The entire project will focus on promoting climate resilient method of agriculture and cultivation that will be monitored within various districts and villages in the state. It also strives at doubling income of state farmers by next few years till 2022 for farmers belonging to medium and small grades to help overcome loses.

Under it, state government will also try and take new measures to help change the pattern of cultivation of the crop depending on the availability of the water. This will help in making the state drought free.


Xian smog tower: China builds world’s biggest air purifier

China has constructed Xian smog tower, an experimental air purifying tower touted to be the world’s biggest at height of over 100 meters (328 feet) in an attempt to fight air pollution.

The tower is built in Xian in Shaanxi province and has brought positive effect on chronic smog problem in China. It is undergoing testing by researchers at Institute of Earth Environment at Chinese Academy of Sciences.

Xian smog tower

Xian smog tower project was announced in 2015 to find low-cost method to artificially remove pollutants from atmosphere such as PM2.5, nitrates and sulphur dioxide which are the most harmful to human health.

The polluted air is sucked into glasshouses of tower and is then heated up by solar energy. The hot air then moves through multiple cleaning filters and helps in reducing air pollution. The system in air purifier also works during winters as coatings on greenhouses enable glass to absorb solar radiation at higher efficiency.

According to its original design, the full-sized tower will reach 500 metres (1,640 feet) high with diameter of 200 metres (656 feet). This tower size will capture greenhouses in nearly 30 square kilometres and will be capable of purifying the air for small-sized city.


During the tests, the tower has managed to produce more than 10 million cubic metres (353 million cubic feet) of clean air day since its launch. It was able to bring down the smog to moderate levels the day when air quality was severe. However, the results were preliminary as of now. It has also improved quality of air after observations were made over distance of 10 square kilometers in the past few months.
