Objectives Know differences between tropical and temperate

environments Differentiate types of agricultural systems Compare and contrast selected farm types, sizes

and operations in other nations Explain how farmers in other countries produce

food. Examples of farming systems

Tropic of Capricorn

Tropic of Cancer

Temperate vs Tropical

• Above 30 Degrees north & south equator

• Rainfall

• Temperature: mild

• Ecosystem

• Low Disease threat

• From equator to 30 Degrees north &south

• Extreme : from almost nothing to >4000 mm

• Hottest to mild temperature

• Fragile ecosystem

• High levels of diseases

Cooler and drier vs. Warm and wet environments

• Less biomass• < Biodiversity• Less complex• More vulnerable

• > biomass (organic matter)• > Biodiversity• Complex food web • Very Fragile environment

• Climate and topography are the most significant environmental factors that determine ecosystem

Climatic Classification

• The modified Köppen climatic classification system organize the world’s regions into six climatic zones

5 based on precipitation: 4 moist , 1 dry

1 based on topography

Earth’s Biomes Classification

• U. S. Forest system classifies earth’s biomes into the following categories:• forest• grassland• desert• tundra

Biomes

• They are macroregional ecosystems based on life -forms (the form, structure,and function of the organisms) rather than on sets of particular species.

• Biomes enable comparisons between regions to improve the understanding of ecosystem process and to establish management practices when new species (crops) are introduced from elsewhere.

U. S. Forest Classification is further divided into 15 categories:
