Trinidad
• Most southern island
• Population: 1.4 M
• Economy: Oil and gas driven
– Agriculture: < 2% GDP
• Mixed population
• Rich culture

Soil Resources
• Survey 1960-70s
• Scale 1:150,000 and 1:25,000
• Soil categorization
– A1-A4: soils of the alluvial plains and valleys
– B1-B2: soils of the terraces
– C1-C4: soils of the uplands
• Soil orders
– All major 12 orders
• Digitized

Erosion Influence on Capability

Water Influence on Capability
![Page 12: Soil Resources, degradation, Conservation and management In Trinidad and Tobago, Gaius Eudoxie - Department of Food Production, UWI - Trinidad and Tobago](https://reader034.fdocuments.in/reader034/viewer/2022050806/587ae4cd1a28ab542b8b70c1/html5/thumbnails/12.jpg)
Soil Issues• Low organic matter
• Low stability
• Soil sealing and crusting
• Low Quality
• Soil loss-erosion
• Mass wasting
![Page 13: Soil Resources, degradation, Conservation and management In Trinidad and Tobago, Gaius Eudoxie - Department of Food Production, UWI - Trinidad and Tobago](https://reader034.fdocuments.in/reader034/viewer/2022050806/587ae4cd1a28ab542b8b70c1/html5/thumbnails/13.jpg)
Elements of Degradation
• EROSION
– Soil physical condition
– Deforestation
– Quarrying
– Inappropriate agricultural practices
• Chemical
– Acidity due to monoculture
– Hydrocarbon pollution

Actions and Activities
• Focus on social effects
– Landslides
– Flooding
• Development of policies and laws
• Signatory to many conventions
• Ministerial focus on erosion

Opportunities• Distinction between
soil and land
• Soil information system
• Erosion modeling
– UWI efforts
• Conservation focus, training and implementation
• Regional effort
