  Economic class 10 Development chapters Q. What is the criterion used by the UNDP for classifying countries? Ans. United Nations Development Programme (UNDP) has used the criterion of Human Development Index to measure the development of countries. HDI is calculated on the basis of: (1) Per capita income: When the total national income of the country is divided by its population, we get the per capita income. (ii) Life expectancy: It measures the average age of a person in a country. It helps us to know the health facilities of a country. (iii) Literacy rate: Education is also one of the most important criteria for the development of a country. (iv) Gross enrolment ratio: It measures the education gained at three levels—at the primary, secondary and higher education level. Per capita income is also calculated in dollars for all countries so that it can be compared easily. HDI has been calculated for about 177 countries. According to it, the rank of India is 131 and the rank of

  Geography What are the causes of land degradation? What are the ways to solve this problem? Ans. Causes of land degradation: (1) Mining sites are abandoned after the excavation work is done, leaving deep scars of overburdening. In states like Odisha, Jharkhand, Madhya Pradesh, Chhattisgarh, deforestation due to mining has caused severe land degradation. (ii) Overgrazing in states like Gujarat, Rajasthan, Madhya Pradesh, and Maharashtra is one of the main reasons behind land degradation. (iii) Overirrigation and waterlogging lead to increase in salinity and alkalinity in the states of Punjab, Haryana and western Uttar Pradesh, thereby leading to land degradation. (iv) Mineral processing like grinding of limestone for cement industry and calcite and soapstone for ceremic industry generate huge quantities of dust in the atmosphere. It stops the infiltration of water in the soil. (v) Industrial effluents as wastes have become a major source of land and water pollution in many part

AGRICULTURE Class 10 geography  Chapter 4 important term and notes for board. Cbse, state and other board exam https://digieducationlearningpoint.blogspot.com/?m=1   Important term 1. Primitive Substance Agriculture is practised with small patches of land with the help of  primitive tools like hoe, Dao and digging sticks, and family/community labour. This type of farming depends upon monsoon, natural fertility of the soil and suitability of other environmental conditions to the crops grown. 2. Slash and Burn Agriculture is a method of agriculture used in the tropics, in which forest vegetation is felled and burned, the land is cropped for a few years, then the forest is allowed to reinvade. 3. Intensive Subsistence Agriculture is a method of agriculture, where farmers get more food per acre compared to other subsistence farming methods. This allows farmers to make the most of each harvest. 4. Plantation usually a large farm or estate, especially in a tropical or semitropical co
