The correct answer is: A. Half
Haryana is a state in northern India. It is one of the most prosperous states in India, with a high per capita income. However, the state also faces a number of challenges, including water scarcity and land degradation.
One of the major problems facing Haryana is the problem of alkalinity and salinity. According to the government of Haryana, about half of the state’s land area suffers from alkalinity and salinity problems. This means that about 10 million hectares of land in Haryana is affected by these problems.
Alkalinity and salinity are caused by the accumulation of salts in the soil. These salts can come from natural sources, such as groundwater, or from human activities, such as irrigation. When the salts accumulate in the soil, they can make it difficult for plants to grow. This can lead to a loss of productivity and a decline in the quality of life for people living in affected areas.
The government of Haryana is taking a number of steps to address the problem of alkalinity and salinity. These steps include:
- Promoting the use of salt-tolerant crops
- Developing new irrigation techniques
- Promoting the use of rainwater harvesting
- Afforestation
These measures are expected to help to reduce the impact of alkalinity and salinity on the state’s economy and environment.
