This document discusses land use change in Cuba after the collapse of the Soviet Union in the late 1980s. It analyzes satellite imagery from 1988, 1998, and 2009 to classify land use and calculate changes in vegetation, urban, and water pixels over time. The results show an increase of around 8655 acres or 3493030 square meters of vegetation from 1988 to 2009, likely due to Cuba shifting to more sustainable agricultural practices during its "Special Period" after losing Soviet support. The document concludes by discussing the results and limitations of the remote sensing analysis.

After the
Collapse:
Land Use change during the “Special
Period”
By Jason Nielsen

2. Objectives
• Discuss the History of Cuba’s Agriculture before and
after the collapse of the Soviet Union
• Discuss Hypothesis and Methods
• Display and Describe Results
• Conclusion and Recommendations

3. Agriculture in Cuba
• Agricultural Reform Law 1959 and the
Green Revolution
o Export Focused Sugarcane
o Oil-centric
o Synthetic Fertilizers and Pesticides
• 229% per Hectare more than US
• Soviet Collapse
• Special Period
o Law 142
o Permaculture
o Organic Farming
• Urban Agriculture in Havana
o Farmers Markets
o By 2000, 26000 Urban Garden producing 25,000 tons of food
o Total Urban Agriculture Production, 113,525 tons of food

4. Hypothesis and Methods
• There must be change!
• Landsat 5 Imagery
o Subset Region of Interest in ENVI 5.0
o Ocean Mask by Extraction in ArcGIS
o Normalized Difference Vegetation Index (NDVI)
o Supervised Classification
o Raster Calculator for Change
o Reclassify total Vegetation Gains
