IMAZON

Overview

Imazon (Instituto do Homem e Meio Ambiente da Amazônia - Institute of Man and Environment of the Amazon) is an independent Brazilian research organization that produces its own deforestation monitoring and analysis.

This dataset provides:

  • Municipality-level deforestation pressure classification: Risk assessment of deforestation threat
  • Pressure categories: Three-level classification system (0, 1, 2, 3) representing deforestation pressure intensity
  • Geographic coverage: Municipalities in the Legal Amazon region
  • Municipal boundaries: Provided as spatial features (shapefile format)
  • Policy-relevant indicator: Used in environmental monitoring and policy assessments

Imazon’s deforestation pressure index helps identify which municipalities face high deforestation risk, valuable for targeted conservation, enforcement, and development planning.

Data Source

Imazon’s classification is based on: - Deforestation monitoring using satellite imagery - Analysis of deforestation trends and drivers - Risk assessment methodology to classify municipalities - Regular updates as monitoring data accumulates

Available Dataset

imazon_shp (Imazon Municipality Pressure Index)

Municipality-level deforestation pressure classification with spatial geometries.

  • Geographic unit: Brazilian municipalities
  • Coverage: Legal Amazon municipalities
  • Variables: Municipality name, state, deforestation pressure category (0-3)
  • Data format: Shapefile / Simple Features (SF) spatial objects
  • Update frequency: Periodic updates as Imazon releases new assessments
  • Use cases:
    • Identify high-risk deforestation municipalities
    • Target conservation resources to threatened areas
    • Analyze geographic patterns of deforestation pressure
    • Environmental risk assessment
    • Monitoring enforcement effectiveness
    • Correlate pressure with socioeconomic variables

Deforestation Pressure Categories

Imazon’s three-level classification system: | Category | Pressure Level | Description | |———-|—|—| | 0 | No/Low Pressure | Minimal deforestation threat | | 1 | Moderate Pressure | Some deforestation risk | | 2 | High Pressure | Significant deforestation threat | | 3 | Very High Pressure | Severe/Critical deforestation risk |

Function Parameters

1. dataset

Only one dataset is available:

dataset = "imazon_shp"  # Imazon municipality pressure classification

2. raw_data

Controls whether to download the original data or the processed/cleaned version.

  • TRUE: Returns raw shapefile data exactly as provided by Imazon
  • FALSE: Returns treated data with standardized English variable names, consistent formatting, and SF object structure
raw_data = FALSE  # logical

3. language

Output language for variable names and documentation.

  • "pt": Portuguese
  • "eng": English
language = "eng"  # character string

Examples

# download treated Imazon deforestation pressure data
data <- load_imazon(
  raw_data = FALSE,
  language = "eng"
)

Data Notes

Data Format

  • Shapefile format: Returned as Simple Features (SF) spatial objects
  • Geometric representation: Municipality polygons with pressure classification
  • Attributes: Municipality name, state, pressure category

Pressure Categories

The 0-3 scale represents Imazon’s assessment of deforestation risk: - Based on historical deforestation trends - Current forest cover - Accessibility and economic drivers - Human pressure factors

Important Limitations

  1. Static classification: This is a classification/index, not time-series deforestation data
  2. Methodology may change: Imazon’s methodology for calculating pressure may be updated
  3. Subjective risk assessment: Classification involves judgment in addition to objective metrics
  4. Not current alerts: This is not real-time detection like DETER; it’s a classification product
  5. Municipal-level only: Finer spatial resolution not available

Using with Other Datasets

This dataset works well in combination with: - DETER: Compare pressure classification with actual recent deforestation - DEGRAD: Correlate pressure with degradation patterns - CEMPRE: Analyze relationship between employment and deforestation pressure - COMEX: Examine trade patterns in high-pressure vs low-pressure areas
