(Step-by-step guide with free tools for smallholder farmers seeking certification)

I thought GPS was exclusively for large corporations,” shares Ibu Siti, an Indonesian smallholder farmer. “Turns out it’s simply coordinates—numbers indicating my farm’s location. Now buyers know my rubber isn’t from recent forest clearing. That matters to them, and crucially, to my income.”

If you’re pursuing sustainable rubber certification, traceability is your essential first step. Here’s exactly how to establish it.

Why Buyers Demand GPS Traceability

Under the EU Deforestation Regulation (EUDR) effective 2025, companies must prove commodities don’t originate from recently deforested land. Without GPS coordinates, your rubber cannot enter European markets, regardless of quality.

Buyers need proof your rubber comes from your specific plot, and that land wasn’t converted from forest after December 2020. GPS coordinates provide this legal documentation.

What You Actually Need

Not required:

1. Expensive surveying equipment
2. Professional land surveyors
3. Complicated software
4. Technical expertise

Actually required

1. Your farm boundary corners identified
2. GPS coordinates recorded (latitude/longitude)
3. Simple written documentation
4. Approximately 2 hours total time

 Step-by-Step GPS Mapping Process

Method 1: Using Free Smartphone Apps

Best apps for farmers

1. Google Maps (already installed on most phones)

1. Free, simple interface
2. Works offline after downloading map area
3. Easy coordinate sharing

2. GPS Fields Area Measure (free download)

1. Designed specifically for farming
2. Calculates field area automatically
3. Saves multiple farm plots

3. Geo Tracker (free version available)

1. Records walking paths
2. Exports coordinates easily
3. Works in remote areas

How to map your farm

1. Download your chosen app (5 minutes)

2. Walk your farm perimeter on a clear day (30-60 minutes)

3. Mark each corner by dropping a pin/waypoint (tap screen)

4. Let the app calculate area and record coordinates (automatic)

5. Screenshot or export the coordinate list (2 minutes)

6. Write coordinates in your farm notebook (10 minutes)

Method 2: Through Your Cooperative

1. Most cooperatives now provide free GPS mapping assistance:
2. Staff member visits with GPS device
3. Walks boundaries with you (validates ownership)
4. Records professional-grade coordinates
5. Provides printed map for your records
6. Costs typically $0-5 per farmer

Real example: In Sumatra, 47 smallholders spent one afternoon with cooperative staff mapping boundaries. Cost per farmer: $3 for printed maps. Within six months, they accessed buyers paying 8% above market rate.

 Method 3: Agricultural Extension Office

1. Government agricultural offices often provide free GPS mapping services:
2. Schedule appointment in advance
3. Officer visits farm with equipment
4. Creates official documentation
5. Provides coordinates and map
6. Completely free in most regions

Recording Your Coordinates Properly

GPS coordinates look like this:

1. Latitude:    7.5564° S
2. Longitude: 110.3156° E

What to record for each corner:

1. Corner number (1, 2, 3, 4, etc.)
2. Latitude coordinate
3. Longitude coordinate
4. Any landmarks (large tree, road intersection, river)

Example documentation:

1. Farm: Pak Budi, 3.2 hectares
2. Corner 1: 2.4532° N, 101.2398° E (near main road)
3. Corner 2: 2.4545° N, 101.2410° E (old mango tree)
4. Corner 3: 2.4538° N, 101.2421° E (stream boundary)
5. Corner 4: 2.4523° N, 101.2407° E (property marker)
6. Date recorded: January 15, 2025

 Common Questions Answered

Q: What if I don’t own a smartphone?

A: Use cooperative or extension office services. Alternatively, borrow a neighbor’s phone for 30 minutes.

Q: Does GPS work everywhere?

A: Yes, GPS satellites cover globally. Dense forest canopy may slow signal acquisition, map on clear days in open areas.

Q: How accurate must coordinates be?

A: Within 5-10 meters is acceptable. Smartphone GPS typically achieves 3-5 meter accuracy perfectly adequate.

Q: What about disputed boundaries?

A: Resolve boundary disputes before GPS mapping. Cooperatives can facilitate neighbor discussions. Clear boundaries are prerequisite for certification.

Connecting Traceability to Certification

GPS coordinates alone don’t guarantee certification, but they’re the non-negotiable foundation. Once established, you’re ready for the [next step: simple record-keeping] that documents your sustainable practices.

Think of traceability as your farm’s birth certificate. Without it, you cannot prove your rubber’s legitimate origins. With it, you unlock access to premium markets willing to pay 5-15% more.
