The Challenges Of Resource Management Flashcards
What is solar energy
energy derived from the sun
How has UK energy mix changes
More renewable sources e.g. wind power- more concern for climate change- less co2 produces
What is food insecurity
a lack of safe food
How can pests affect food supply
They can eat crops e.g. locusts devour whole fields
To what extent can appropriate technology and other strategies increase food supply
Appropriate technology: Low-cost, sustainable methods (e.g., drip irrigation, drought-resistant crops) increase food production in developing countries.
Increased efficiency: Tools like greenhouses or hydroponics optimize land use and water conservation.
Sustainable farming: Crop rotation, agroforestry, and organic farming maintain soil health and boost yield.
Challenges: High costs, lack of infrastructure, and climate change can limit effectiveness.
Conclusion: While appropriate technology can significantly boost food supply, it’s not a complete solution without addressing environmental and economic challenges.
Case study- Almeria
Almería is part of the Andalusia region.
Known for its low rainfall and hot, dry summers. Almería is home to the largest concentration of greenhouses in the world, (26000 hectares) The region supplies much of Europe, especially Northern Europe, with fresh produce.
Impacts and benefits of almeria
Long-term impact: Large-scale greenhouse farming made Almería into a major vegetable exporter.
Environmental issues: Overuse of water, pesticide use, and soil degradation threaten sustainability.
Social issues: Influx of migrant workers has led to overcrowded housing, low wages, and poor living conditions.
Economic benefits: Significant job creation, economic growth, and trade with Europe, but concerns over long-term stability due to environmental challenges.
