Case study Piura Current Lecture3 main regions1. Coastal: 11% of land area, 50% of population, main cities and industry2. Andes Mountains: 33% of land area, 40% of population3. Amazon Basin: 58% of land area, some high value agricultureAgriculture in Peru - Agriculture was main source of GDP until WWII- Big push into mining, forestry, and other industries after the 1940s- Today agriculture is 8.5% of GDP- Agriculture employs 37% of the total population- 1.8 Million farms- Of rural farming population, only 1 in 8 people own their own land and have access to formal creditSoil degradation problems in Peru1. Salinity- Primarily in the intensive agriculture of the coastal region2. Erosion- Primarily in subsistence agriculture of the Andes Mountain region Case study Piura Agriculture in Piura—95% of farms are less than 5 hectares (accounting for 75% of cultivated land).These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Increased salinization affecting 20% of Piura cropland in 1963 to 40% in 2000Direct cause: necessary but problematic irrigation systems that channel water from the Andes East to West. Still have pre-Inca canals that are used in some areas.Indirect causes- Emphasis on rice monoculture- Emphasis on use of agrochemicals- Lack of access to credit Promising pilot goals- Recoup highly salinized lands- Reduce input costs- Increase profits- Improve food
