3.4.2 Agricultural Systems and Sustainability

• What is an example of an input in an agricultural system?

  Seeds
• An organic agricultural system avoids the use of synthetic fertilizers and pesticides
• Sustainability in agriculture means meeting present food needs without compromising future generations.

  True
• What environmental challenge involves the overuse and pollution of water resources for agriculture?

  Water scarcity
• What type of agricultural waste can pollute water resources?

  Chemical runoff
• What agricultural activity is a significant contributor to greenhouse gas emissions?

  Livestock production
• What are three causes of soil degradation in agriculture?

  Loss of fertility, erosion, contamination
• An agricultural system consists of interconnected components involved in producing food and fiber.


  True
• What is the primary focus of subsistence farming?

  Personal or local consumption
• What technology is used in precision farming to optimize agricultural practices?

  GPS and sensors
• The environmental dimension of sustainability focuses on minimizing negative impacts on natural resources
• What is the primary consequence of soil degradation in agriculture?

  Reduced long-term productivity
• What type of agricultural waste leads to environmental degradation?

  Chemical runoff
• Addressing inequalities and power imbalances in access to land, credit, and markets falls under the social aspect of equity
• Addressing social and economic challenges in agriculture is crucial for achieving sustainable and resilient agricultural systems
• What is one purpose of crop rotation in agriculture?

  Improving soil fertility
• Match the sustainable agricultural practice with its description:

  Organic Farming ↔️ Avoids synthetic inputs

  Precision Farming ↔️ Optimizes input use

  Crop Rotation ↔️ Improves soil fertility

  Agroforestry ↔️ Integrates trees into systems
• Agroforestry diversifies farm income and increases overall productivity
• Agroforestry involves integrating trees and crops in agricultural systems.


  True
• What are the three main challenges that sustainable agricultural practices aim to address?

  Environmental, economic, social
• What is the purpose of certification and labeling in sustainable agriculture?

  Identify sustainable products
• What ecological principles does agroecology apply to agricultural systems?

  Soil health, biodiversity
• Sustainability in agriculture balances environmental, economic, and social dimensions.


  True
• Sustainable agriculture ensures the long-term profitability and viability of agricultural enterprises


  True
• Biodiversity loss in agriculture is caused by habitat destruction, pesticide use, and monoculture farming
• An agricultural system is a set of interconnected components involved in producing food and fiber
• What type of agricultural system focuses on producing food for personal consumption with limited technology?

  Subsistence
• Which farming system uses GPS and sensors to optimize inputs for specific conditions?

  Precision
• Soil degradation is a key environmental challenge caused by unsustainable farming practices
• Livestock production and fertilizer use are major contributors to greenhouse gas emissions
• Biodiversity loss in agriculture is partly caused by habitat destruction and the use of pesticides
• Addressing environmental challenges in agriculture is crucial for ensuring the long-term sustainability
• Rural development in agriculture aims to support the well-being of rural communities
• Match the components of an agricultural system with their descriptions:

  Input ↔️ Resources used in production

  Process ↔️ Activities like planting

  Output ↔️ Products generated
• Organic farming uses synthetic fertilizers and pesticides.

  False
• What is the primary goal of sustainability in agriculture?

  Meet present needs without compromising future generations
• Match the dimension of sustainability with its focus:

  Environmental ↔️ Minimizing ecosystem impacts

  Economic ↔️ Ensuring profitability

  Social ↔️ Promoting rural well-being
• Greenhouse gas emissions from agriculture contribute to climate change.


  True
• Ensuring fair wages, working conditions, and access to resources for farmers and farm workers falls under the social aspect of livelihoods
• What is one goal of rural development in agriculture?

  Promoting economic opportunities
