2. Based on the Purpose of Production:
3. Based on the Method of Farming:
4. Based on Environmental Conditions:
5. Based on Geographic Regions:
6. Based on Technological Advancement:
34
Types of Based on the Scale of Operation :
Subsistence Agriculture:
Commercial Agriculture:
35
Small-scale farming for personal use. Minimal use of modern technology. Example: Traditional rice farming in remote villages;Traditional Rice Farming in Ifugao's Rice Terraces
Subsistence Agriculture:
36
Large-scale farming aimed at market sale. High use of technology and inputs. Example: Pineapple Plantations in Bukidnon; Large corn plantations in the Midwest USA
Commercial Agriculture:
37
Types of Based on the Purpose of Production:
Food Crops Agriculture
Cash Crops Agriculture
Mixed Farming:
Industrial Agriculture
38
Grows crops for human consumption.
Example:Rice Farming in Nueva Ecija. Nueva Ecija, often referred to as the "Rice Granary of the Philippines," is a prime example of food crops agriculture;
Wheat farming in the Punjab region.
Other Examples of food crops: Corn, Banana, Cassava, Coconut, Mango, Pineapple
Food Crops Agriculture
39
Produces crops for sale and profit.
Example: Coconut Plantations in Quezon Province. Quezon Province is known for its extensive coconut plantations, where coconuts are grown primarily as a cash crop.
The coconuts are processed into various products like copra, coconut oil, and desiccated coconut, which are then sold domestically and internationally, generating income for farmers and contributing to the local economy.
Coffee plantations in Colombia.
Cash Crops Agriculture
40
Combines crop cultivation with livestock.
Example:Integrated Rice-Fish Farming in Iloilo. In Iloilo, particularly in the rural areas, farmers practice mixed farming by combining rice cultivation with fish farming.
This method allows them to produce both food crops (rice) and livestock (fish) within the same agricultural system.
The integration of fish into rice paddies helps control pests and provides an additional source of income and nutrition.
Dairy and vegetable farms in the Netherlands.
Mixed Farming:
41
Focuses on producing raw materials for industries.
Example: Sugarcane Plantations in Negros Occidental. Negros Occidental is a major hub for sugarcane production in the Philippines.
The sugarcane grown here is primarily used as a raw material for the sugar industry, which includes the production of refined sugar, ethanol, and other sugar-based products.
The large-scale, industrial nature of these plantations supports both local and international markets; Oil palm plantations in Malaysia.
Other examples of industrial crops: abaca, rubber, cofffee, coconut, Pineapple, tobacco

58
Types of Ecosystem Services Beneficial to Agriculture
Pollination and natural pest control.
Soil formation and nutrient cycling.
Water Regulation and Purification
The role of biodiversity in resilient farming systems
59
Many crops rely on pollinators such as bees, butterflies, and other insects for fruit and seed production. Healthy ecosystems support a diverse community of pollinators, essential for the productivity of crops like fruits, vegetables, and nuts.
Pollination and natural pest control.
60
Healthy ecosystems contribute to soil formation through the breakdown of organic matter and the accumulation of minerals. This process creates fertile soil, which is critical for crop growth.
Soil formation and nutrient cycling.
61
play a key role in recycling nutrients, such as nitrogen and phosphorus, making them available for plant uptake
Microorganisms, fungi, and plant roots
62
Ecosystems like forests and wetlands regulate water flow by absorbing rainfall, reducing runoff, and preventing soil erosion.
Water Regulation and Purification
63
Diverse ecosystems enhance the resilience of farming systems by providing a variety of species that can adapt to changing conditions.
