1. Plantation farming in Tropical Rainforest Case Study: Coffee plantation in Brazil

2. Characteristics of plantation farming in TRF usually a large farm or estate, especially in a tropical or semitropical country, on which cotton, tobacco, coffee, sugar cane, are cultivated, usually by resident laborers an intentional planting of a crop, on a larger scale most of these involve a large landowner with a number of employees carrying out the work plantings of trees and shrubs.  cereal production or pasture. plantings maintained on economic bases  subsistence farming

3. Different types of plantation High value food crops –Plantings of a number of trees or shrubs grown for food or beverage, including tea, coffee, and cacao Arable crops –These include tobacco, sugar cane, pineapple, and cotton, especially in historical usage.

4. Sugar –Sugar plantations were highly valued in the Caribbean by the British and French colonists in the 16th and 17th centuries and the use of sugar in Europe rose during this period. Sugarcane is still an important crop in Cuba. Rubber Orchards –Fruit orchards are sometimes considered to be plantations. Sugarcane plantation in rural Cuba

5. Coffee plantation in Brazil Coffee was introduced in Brazil in 1727 from French. Initially it was planted only for domestic use. Today, Brazil is the world's largest coffee producer and produces around 25% of the world’s supply of coffee. The vast majority of coffee farms in Brazil are less than 10 hectares in size. 71% of farms : less than 10 hectares 25% of farms : less than 50 hectares 4% of farms : larger than 50 hectares

11. Coffee and the environment Originally, coffee farming was done in the shade of trees –provided natural habitat for many animals and insects –farmers used compost of coffee pulp and excluded chemicals and fertilizers –rotated crops and cultivated food alongside their cash crops, which provided additional income and food security

13. But…… Shade-grown techniques was replaced by sun cultivation techniques in order to increase yields. Great investment  coffee crisis  increased technification  increase productivity

15. Different types of growth: * 鄉村式（ Rustic ） * 老式混合種植（ Traditional polyculture ） * 商業混合種植（ Commercial polyculture ） * 樹蔭單一種植（ Shaded monoculture ）

16. Sun cultivation –involves cutting down trees, and high inputs of chemical fertilizers and pesticides. –Environmental problems ( effects of most modern coffee farms ) Deforestation pesticide pollution habitat destruction soil and water degradation biodiversity on the coffee farm and in the surrounding areas suffer.

17. Biodiversity --- Birds and coffee plantations Shade-grown coffee plantations harbor a diversity of many living things, orchids, insects, and mammals, for example. The multi-layered vegetation of shade-grown coffee plantations provides food (e.g. invertebrates and nectar) and cover for migratory and resident birds which are in some cases very similar to native forest. At the same time, birds and insects help to propagate pollen. However, there are so many habitats in the tropics being cleared for agriculture under sun-grown techniques.

19. Vicious cycle of sun cultivation Deforestation Soil erosion + decreased fertility of soil Abandon farmland Exploitation for income

20. Shade V.S. Sun Shade-grown coffee plantations The majority of bird species are feeding in the shaded overstorey. dead leaves from the overstorey trees provide nutrients to the coffee shrubs as they decay. fewer weeds in shade plantations, because fallen leaves from overstorey trees in shade plantations act as natural mulch. Sun cultivation monocultures do not support a diversity of birds. nutrients are not available, so fertilizers must be used Herbicides are needed to control weeds. Soils are more exposed to the elements, particularly rains of tropical areas. –more erosion of topsoil, and the leaching of chemical fertilizers, pesticides, and herbicides into local watersheds which causes water pollution in the nearby rivers or lakes. grow faster and age more quickly than those grown in shade, and therefore must be replaced more often, specifically at about 6 versus 30 year intervals, respectively.

21. What can be done? Use composting and other natural methods such as the planting of nitrogen-fixing trees or applications of animal manures.  Improve and maintain soil fertility Use ecological methods  Control pests and disease Provide much refuge for migratory birds and other wildlife. Protect plant diversity by planting different species of native trees. “Reforesting” or maintaining forested areas offering jobs at labor-intensive times such as harvest => Provide economic security in rural regions reducing water use, recirculating water whenever possible, and employing anaerobic digestion systems to clean water after use => Minimize pollution from coffee processing wastewater Follow stringent organic standards to produce a quality crop and to meet organic certification requirements. Protect and further a traditional agriculture, building on centuries-old knowledge of farming in harmony with nature.

22. What can be done? Setting up law: –The Brazilian Forest Code is a law that states that in certain areas, a proportion of the land must be permanently preserved for conservation of natural resources and wildlife.Brazilian Forest Code –In the cerrado, the percentage is 35%.
