FAQs on Agriculture in Environment Video Lecture - Environment for UPSC CSE

1. What is the impact of agriculture on the environment?
Ans. Agriculture has both positive and negative impacts on the environment. On one hand, it provides food and raw materials, supports rural economies, and helps maintain biodiversity. On the other hand, it can lead to deforestation, soil degradation, water pollution, greenhouse gas emissions, and loss of habitats.
2. How does agriculture contribute to climate change?
Ans. Agriculture contributes to climate change through various ways. For example, the production of livestock releases methane, a potent greenhouse gas. Additionally, the use of synthetic fertilizers and intensive farming practices can lead to nitrous oxide emissions. Deforestation for agricultural purposes also releases large amounts of carbon dioxide into the atmosphere.
3. What are the sustainable practices in agriculture to protect the environment?
Ans. Sustainable agriculture practices aim to minimize environmental impact while maintaining productivity. These practices include organic farming, agroforestry, crop rotation, precision agriculture, and integrated pest management. These methods promote soil conservation, reduce chemical inputs, conserve water, and promote biodiversity.
4. How does agriculture affect water resources?
Ans. Agriculture can have significant impacts on water resources. Excessive use of water for irrigation can deplete groundwater reserves and lead to water scarcity. The use of fertilizers and pesticides in agriculture can also contaminate water bodies, affecting aquatic ecosystems and human health. Proper water management techniques, such as drip irrigation and water recycling, can help minimize these impacts.
5. What role does agriculture play in biodiversity conservation?
Ans. Agriculture plays a crucial role in biodiversity conservation. Traditional farming practices, such as maintaining diverse crop varieties and preserving traditional farming landscapes, help preserve genetic diversity in plants and animals. Additionally, sustainable agricultural practices that promote natural habitats, such as agroforestry and organic farming, provide important habitats for various species, contributing to overall biodiversity conservation efforts.
