    Study Notes

    Agriculture in the (Sub-)Tropics

    • Plantation farming is a commercial farming method, cultivating cash crops solely for global markets.
    • Large tracts of land are required, often leading to deforestation.
    • These farms are typically located in tropical regions with high temperatures and rainfall.
    • Monoculture farming practices (growing a single crop) are common, utilizing excessive fertilizers and pesticides.
    • Sustainability concerns arise from deforestation, nutrient depletion, biodiversity loss, and pollution.
    • Labor conditions and compensation are often poor for workers in plantations.
    • Shifting cultivation (slash-and-burn agriculture) is used in tropical regions, where land is cleared and cultivated for a few years, then abandoned to regenerate.
    • The cleared land's nutrients are replenished by natural decomposition and ash from the burning.
    • This agricultural method requires a long fallow period before the plot can be used again.
    • Agroforestry combines trees and shrubs (forestry) with food and livestock production, for shade and nutrient enrichment for crops.
    • Livestock farming, raising domesticated animals (for meat, dairy products and other resources) is practiced extensively.
    • Dry farming is practiced in regions receiving less precipitation or in drier climates.
    • Irrigation farming utilizes irrigation to increase crop yields in arid and semi-arid zones.
    • Irrigation methods vary based on expense, water availability, soil type and terrain, including channels, sprinklers, and drip systems.
    • Fertilizers are substances that enhance plant growth, and pesticides/herbicides are applied to control pests and weeds.

    Green Revolution

    • A widespread introduction of industrial agriculture in developing countries (mid-20th century).
    • Increased food grain yields (especially wheat, rice, and corn), through improved varieties and technologies
    • Increased food supplies and self-sufficiency in some regions
    • Negative consequences involve environmental damage and social inequalities.
    • The use of chemicals (fertilizers & pesticides) had harmful effects on the soil, humans, and the environment.
    • Intensive farming practices led to a decline in biodiversity.
    • A widening gap between large and small farmers is a negative consequence for social inequalities.

    Environmental Problems of Agriculture

    • Water shortage in various regions can limit agricultural potential through intensive irrigation and usage.
    • Sinking groundwater levels are caused by over-usage of water sources.
    • Soil salinization, a widespread soil degradation issue, develops through irrigation in arid and semi-arid regions where water readily evaporates leaving behind salts.
    • Soil erosion: natural processes or human activities contribute to soil loss.

    Feedlots

    • Open-air facilities to raise cattle, featuring labor-saving technological investments for feeding and waste removal.

    Agribusiness

    • Agricultural practices and related activities, focused on intensification and specialization.
    • Intensification leads to increased yields through technology and intensive methods (e.g., high inputs).
    • Specialization concentrates on specific types of crop or livestock.
    • Mechanization involves greater use of machinery (e.g., tractors, harvesters), enhancing efficiency and productivity.

    Aquaculture/Aquafarming

    • The cultivation of aquatic organisms (fish, shellfish, and plants) in controlled environments (e.g., ponds, tanks, or cages in the ocean)
    • Can address the demand for seafood, in conjunction with the threat of overfishing.
    • Environmental concerns, waste products and escape of captive species posing a risk to wild populations.

    Technological Advancements and Development

    • Agricultural productivity has improved, with greater yields per worker and reduced time-spent on labor.
    • Technological advancements like machinery and robots have enhanced the efficiency of the overall process, but also introduce reliance on energy and capital investments.
    • Specialization and vertical integration (combining various stages of production within one or multi factories) are also noted.
    • This consolidation results in large companies controlling numerous aspects of the agricultural production and supply chains.

    Increasing Agricultural Productivity

    • Greenhouse cultivation, a significant agricultural sector in the Netherlands, is intensive and specialized, yielding high productivity.
    • The cluster structure (greenports) in the Netherlands, brings together diverse companies across the horticultural supply chain and promote trade and efficiency.

    The Rise of Genetic Engineering

    • Genetic engineering is used to enhance yield and disease/pest resistance in crops.
    • Benefits include higher yields, reduced reliance on pesticides and fertilizers.
    • Potential downsides include environmental damage from contamination of non-engineered plants, and potential unknown health risks.
    • Alternative methods (e.g., the SRI method in rice cultivation in Vietnam) exist and emphasize higher yields and efficiency with lower input needs.
