• What is Hydroponics?


  Hydroponics is a method of growing plants without soil, using mineral nutrient solutions in an aqueous solvent.
• Why is Hydroponics suitable for Lagos?

  Urbanization limits space for traditional farming. High population growth increases food demand. Controlled environment less dependent on weather.
• How does Hydroponics work?

  Plants grow in a water-based, nutrient-rich solution. Supported by materials like perlite, gravel, or mineral wool. Environment controlled for temperature, light, and humidity.
• What are the benefits of Hydroponics?

  Space-efficient: Can be set up in urban areas. Water conservation: Uses up to 90% less water. Faster growth: Optimal nutrient delivery. Reduced pesticides: Controlled environments.
• What are the challenges of Hydroponics?

  High initial setup costs. Requires specialized technical knowledge. Can be energy-intensive.
• Give examples of Hydroponics in Lagos?


  Small-scale urban farms growing vegetables like lettuce and spinach. Community projects by NGOs and local governments in schools and communities.
• What is the impact of Hydroponics in Lagos?

  Increases local food production, enhancing food security. Creates employment opportunities. Promotes sustainable agricultural practices.
• Indira Gandhi Canal - Overview


  Purpose: Provides water for irrigation. Location: Thar Desert.
• Impact of Indira Gandhi Canal on Farming

  Irrigation: Enables the growth of crops in an otherwise arid region. Types of Crops: Wheat, mustard, cotton.
• Benefits of Irrigation from Indira Gandhi Canal

  Increased Food Production: More reliable crop yields. Economic Growth: Boosts local agriculture economy. Food Security: Improves availability of food.
• Challenges Overcome by Indira Gandhi Canal

  Water Scarcity: Provides a consistent water supply. Extreme Temperatures: Mitigates the impact of high evaporation rates.
• Social Benefits of Indira Gandhi Canal

  Employment: Creates jobs in farming and related industries. Community Development: Supports local communities through improved food supply.
• Environmental Impact of Indira Gandhi Canal

  Desert Greening: Transforms arid land into fertile farmland. Biodiversity: Supports a wider range of plant and animal life.
• Long-term Sustainability of Indira Gandhi Canal

  Water Management: Requires careful management to prevent overuse. Maintenance: Regular upkeep needed to ensure efficient water delivery.
• Global Patterns of Food Supply and Demand

  Climate: Weather conditions and climate change impact crop yields. Technology: Advances in agricultural technology can increase food production. Conflict: Wars and political instability can disrupt food production and distribution.
• What is food security and what causes food insecurity?

  Food Security: When all people have access to sufficient, safe, and nutritious food. Causes of Food Insecurity: Poverty: Lack of financial resources to buy food. Population Growth: Increased demand for food. Environmental Factors: Droughts, floods, and other natural disasters.
• Methods to Increase Food Supply

  Irrigation: Artificial application of water to land. Aeroponics: Growing plants in an air or mist environment without soil. Hydroponics: Growing plants in a water-based, nutrient-rich solution. Green Revolution: Use of high-yield crop varieties and modern agricultural techniques. Biotechnology: Genetic modification of crops to improve yield and resistance.
• Examples of Sustainable Food Production Methods

  Organic Farming: Avoids synthetic chemicals, promotes biodiversity. Permaculture: Design of agricultural systems that mimic natural ecosystems. Urban Farming: Growing food in urban areas to reduce food miles and increase local food security.
