My discussion on this topic last week (South Express dated 8.3.25) has kindled some good reactions from the readers. I thought of working on their feedback. According to one reader, going by the per capita data of tree cover, if we take India’s tree cover of 28 trees per head, and multiply it by total population of 145 crore, it works out to roughly 4000 Cr trees in India, and if we increase the trees to China’s level of 130 per head, then Idia’s tree cover will be even better than China; which means India will have roughly 18000 Crore trees. The reader further made an interesting observation. He assumed that India’s land area would not be sufficient if we provided an average of 20 sq meters per tree. Thanks for the data interpretation he made. Thousands of green activists like him are there who want India to have better natural resources. He also agreed that we should compare ourselves with the tropical countries. The green cover in a country depends on its climatic zone. Tropical climate is different from temperate and polar climates. Even within tropical countries, wet, dry, monsoon, and desert climates exist. We cannot expect dense growth in dry areas. In deserts, there is no chance of tree cover except in oases.  Even in temperate regions, where we experience four distinct seasons, the climatic conditions differ between Mediterranean, subtropical, marine and continental areas. All these substantiate the weakness in using the per capita statistical tool. It is like saying that India’s per capita income is Rs 2 lac, which includes the richest individual’s income that may run to billions of dollars. If we exclude the top 100 richest individuals’ income, the average per person earning would be too small.  Poverty is a parameter that should not be estimated from statistical tools but by making proper sustainable development goals to bring a smile to the faces of the poorest. In my last editorial, (8.3.25) I said that population cannot be a yardstick for calculating tree cover and substantiated my logic with an example. One reader accepted that and requested me to compile the data on trees per sq km to compare between countries. In my view, as explained above, that also may not be a correct method as different climatic zones make the exercise a futile one.  But with the help of the worldometers website data, as per the link  https://www.worldometers.info/world-population/population-by-country/, an attempt is made here to compare the status of the same countries appearing in the viral ecard. In other words, the countries taken in the ecard published in last week’s editorial. The results are given in the table below

A quick interpretation of the result is made below.

• The climatic conditions, such as temperature, sunlight, rainfall, and human action, do have a bearing on the tree density
• A warm and humid climate with ample sunlight and consistent rainfall are most suitable for tree growth
• Canada, a temperate country having a vast land mass and less population density, tops the tree cover
• USA and China have a more or less similar sized land area, but USA has better tree cover, but the population density in China is five times that of USA.
• When we compare India with the US and China, we have just a third of the land area, and half of the trees per sq km. So, the tree cover is not that gloomy as depicted
• If the scientific methods of defining the global standards for analytical purposes, the researchers must consider various parameters like climate conditions, population density, and availability of land area

Trees per person versus Trees per Sq KM

Based on the data on population density, land area, and climatic condition, it is felt that India is reasonably keeping its green cover. Simply blaming India for having the least tree cover per person, is a futile exercise and will serve no purpose. However, efforts must be geared up to ensure that at least one third of its present density per sq km must be increased. In other words, 13533 trees per sq km must be increased to 18000 trees per sq km. In India, if the policymakers make a target-based approach to improve the green cover, there should not be any problem in reaching the global standards.
