There is no application of chemical/inorganic fertilizers at all in this. 4. The scope for intercropping is more in this compared to the conventional method of cultivation. Select the correct answer using the code given below.
Explanation
The Sustainable Sugar Initiative (SSI) was launched jointly by International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and World Wide Fund for Nature (WWF).

Statement 1 is correct: The Sustainable Sugarcane Initiative (SSI) is an innovative set of agronomic practices that involves using less seeds, raising seeds in a nursery, and following new planting methods. Statements 2 and 4 are correct: SSI provides ample scope for intercropping and the drip irrigation method as it incorporates wider seed spacing and better water and nutrient management to increase the cane yields significantly.

Q32. Consider the following international agreements: 1. The International Treaty on Plant Genetic Resources for Food and Agriculture. 2. The United Nations Convention to Combat Desertification. 3. The World Heritage Convention Which of the above has/have a bearing on biodiversity?
Explanation
Option 1 is correct: The International Treaty on Plant Genetic Resources for Food and Agriculture, also known as the Seed Treaty, was adopted during the 31st session of the United Nations Food and Agriculture Organization (FAO) in 2001. India is a signatory to this treaty, which directly impacts biodiversity, as seeds are crucial for the conservation of plant genetic resources.
Option 2 is correct: United Nations Convention to Combat Desertification (UNCCD) was established in 1994. It is the sole legally binding international agreement linking environment and development to sustainable land management. Habitat loss to meet our demand for food, raw materials or buildings is the leading cause of species extinction. Conserving, restoring, and sustainably managing habitats and ecosystems is recognized as the most effective way to protect biodiversity. One powerful example is the Great Green Wall. The Wall is an African-led initiative to restore biodiversity.
Option 3 is correct: World Heritage Convention (1972) of UNESCO is concerned with the protection of the World Cultural and Natural Heritage. It acknowledges how people interact with nature and the critical necessity to maintain their delicate equilibrium. World Heritage properties/sites are some of the most outstanding places on the planet and constitute a significant subset of the protected area system, critical for conservation of ecosystem integrity and biodiversity.

Q34. If a wetland of international importance is brought under the ‘Montreux Record’, what does it imply?
Explanation
The ’Montreux Record’ is a register of wetlands listed under the Ramsar Convention that have experienced, are experiencing, or are expected to experience changes in their ecological character. These changes may be due to factors like technological development, pollution, or other human influences. The Ramsar Convention, established in 1971 in Ramsar, Iran, is an international agreement aimed at the "conservation and sustainable use of wetlands." It is not a regulatory framework, but rather the only global treaty specifically focused on the preservation of wetlands. According to the Ramsar Convention, wetlands include all areas of marsh, fen, peatland, and water, whether natural or man-made, permanent or temporary, and with freshwater, brackish, or salt-water, whether flowing or static. This definition also includes marine areas with a depth of less than six meters at low tide. World Wetlands Day is celebrated on February 2nd each year.

Statements 2 and 3 are incorrect: Provisions mentioned in statements 2 and 3 have no bearing upon National-Green Tribunal:
Article 275(1) of the Constitution of India guarantees grants-in-aid from the Consolidated Fund of India each year for promoting the welfare of Scheduled Tribes. Infrastructure development schemes like protected drinking water, road connectivity, electricity and housing are provided under this scheme. 243A provides that a Gram Sabha may exercise such powers and perform such functions at the village level as the Legislature of a State may, by law, provide.
