    Study Notes

    Agricultural Limitations

    • Despite extreme temperatures (50°C) and low rainfall (100mm/year) in the Negev Desert, Israel, agriculture is possible and even exports food.
    • Factors that condition agriculture are:
      • Climate: extreme temperatures and humidity affect agriculture, but invernaderos (greenhouses) can provide optimal conditions.
      • Relief: altitude and slope affect agriculture, with chairas and vales being more suitable.
      • Soil: texture and composition determine the types of crops that can be grown, but humans can correct these conditions or use artificial soils.

    Agricultural Landscape

    • The need to ensure food for the population has led to the extension of industrial monocultures, with 60% of calories coming from just four species (rice, wheat, corn, and potatoes).
    • This has led to the creation of "green deserts" that put biodiversity at risk.

    Crop Plots

    • Plots can be small (minifundios) or large (latifundios) and have regular or irregular shapes.
    • Plots can be separated by walls, hedges, or fences, creating a closed landscape (bocage) or remain open.
    • Plots can be used for agriculture, livestock, or forestry, and properties may change activities over time.

    Farming Practices

    • Farming practices vary according to:
      • Crop variety: specializing in one product (monoculture) or growing multiple species (polyculture).
      • Crop type: herbaceous (cereals) or woody (arbustive or arboreal).
      • Intensity: intensive farming aims for maximum yield, while extensive farming depends on the cultivated area.
      • Irrigation systems: rainfed or irrigated crops.
      • Techniques: traditional or modern, using machines and technology to increase productivity.

    Rural Settlements

    • Rural settlements can be:
      • Concentrated: a group of houses in one location, leaving the rest for cultivation.
      • Dispersed: scattered houses throughout the territory, near each family's farm.
