Share This Post

FEBRUARY 2026 

ISSUED BY 
Global Platform for Sustainable Natural Rubber 

Introduction & Background 

The Global Platform for Sustainable Natural Rubber (GPSNR) is an international, multi-stakeholder, voluntary membership initiative seeking to lead improvements in the socioeconomic and environmental performance of the natural rubber value chain. Members of the platform include tire manufacturers, rubber suppliers and processors, vehicle makers and NGOs. Representatives from each of these stakeholder groups have contributed to the development of the Singapore-based platform and the wide-reaching set of priorities that will define strategy and objectives.

The GPSNR Assurance System, designed by Assurance Services International (ASI) and for GPSNR members, is a risk-based framework that supports credible and independent assurance processes. It enables companies to identify and mitigate human rights and environmental risks within their supply chains, undergo third-party verification, and report transparently on their progress through credible claims.

As part of its Assurance System, GPSNR operates an oversight mechanism to ensure that approved Assurance Service Providers (ASPs) deliver assessment and assurance services in conformity with GPSNR requirements. This oversight function is a critical component of maintaining the credibility, consistency, and integrity of the GPSNR Assurance System.

GPSNR is therefore seeking proposals from qualified and experienced individuals or organizations to provide GPSNR Oversight Assessor services in accordance with GPSNR oversight procedures and requirements.

Request For Proposal – GPSNR-RFP-A02-032-Thailand GAP Coaching

Introduction & Background

 
 The Global Platform for Sustainable Natural Rubber (GPSNR) is an international, multi-stakeholder, voluntary membership initiative seeking to lead improvements in the socioeconomic and environmental performance of the natural rubber value chain.
Development of GPSNR was initiated by the CEOS of the World Business Council for Sustainable Development (WBCSD) Tire Industry Project (TIP) in 2018. Members of the platform include tire manufacturers, rubber suppliers and processors, vehicle makers and NGOs. Representatives from each of these stakeholder groups have contributed to the development of the Singapore-based platform and the wide-reaching set of priorities that will define strategy and objectives.

 

Thailand is the largest producer of natural rubber (NR) worldwide, contributing 36% to
total global production. Majority of the NR production in Thailand is conducted
by smallholder farmers owning land of 2-4 hectares. The NR value chain in Thailand has historically been supported by various governmental bodies, now functioning under the umbrella of the Rubber Authority of Thailand (RAOT). This has led to exceptional performance by rubber farms, with an average yield exceeding 1.6 tons per hectare in 2019. However, the NR value chain in Thailand remains highly labour-intensive and currently
faces oversupply and low prices.

Thailand rubber has some specific particularities. It is grown in 4 main regions with different growing conditions: Traditional areas are in the South (the historical planting) and the East (Rayong and Chanthaburi provinces) while more recent developments were established in less climatically favourable areas: North and North-East (Esan). It has the particularity to be produced almost exclusively by smallholders, using higher tapping frequencies than other countries even in the neighbourhood, and to exploit rather low size farms (1.5ha or less). Share cropping among farmers and tappers is a common practice, beside family farming. Consequence of this is that although a good land productivity (kg/ha), labour productivity remains very low to date.

GPSNR, through the Smallholders Representative and Capacity Building Working Group (SCB WG) – Thailand National Subgroup, is currently inviting proposals for the dissemination of coaching materials and implementation of coaching on Good Agricultural Practices (GAPs) for smallholders in two regions (North and North-East) of Thailand, with a focus on one province per region.

 

The proposed coaching programs should be implemented in accordance with the
GPSNR’s environmental and social commitments and values, as outlined in the GPSNR
Policy Framework[1], and in compliance with the relevant Thai Agricultural Standard: Good Agricultural Practices issued by the Ministry of Agriculture and Cooperatives
of Thailand
.

Objectives

 

The overall objectives of the GAP coaching programmes are to ensure the long-term sustainability of rubber livelihoods and ecosystems by increasing smallholders’ productivity, yields, and socio-economic resilience, whilst safeguarding nature and the environment. 

 

Expected Deliverables

 

Brief Justifications

The objective of the project is to update and disseminate the best Good Agricultural Practices (GAPs) recommendations to farmers in Thailand. This aims to ensure that planters have access to relevant knowledge and resources to enhance their productivity,
motivation, and income, leading to an improved livelihood.

The proposal should implement GPSNR’s proposed strategy for capacity building in
Thailand and provide brief justifications on the most suitable approach to
conduct coaching for smallholders in two regions (North and North-East) of
Thailand, with a focus on one province per region.

The GPSNR SCB WG – Thailand National Subgroup may prioritize funding for coaching in
regions based on relative productivity, coverage of existing coaching services,
socio-economic needs, recommendations of RAOT, or other considerations.

Proposed Coaching Approach

Possible approaches for consideration include (non-exhaustive): mobile coaching at local
community centres; building physical training centres; on-farm coaching; hybrid
coaching approaches. The proposal should consider which approach represents the
best fit for community needs and dynamics.

The proposed coaching approach should consider, but is not limited to, the
following priorities:

a.    Coaching based on the train-the-trainers (ToT) model

b.   Female and other minority inclusion and representation

c.    Field coaching (or other approach) implementation plans

d.   Integration of technology for data capture and ongoing engagement, and progress tracking (i.e. immediate and longer-term monitoring and evaluation)

e.   Others (i.e. nuanced approaches to meet geographic/other needs; ongoing farmer community connectivity and interactions; engagement with local or regional officials

Service providers are to adapt the provided GPSNR GAP coaching approaches. The GPSNR GAPs are created to serve as general best practices and principles for global usage and are periodically reviewed and updated to reflect the sector’s latest understandings.

The service provider is expected to work with GPSNR to adapt the general GAPs to align with local situations in Thailand and comply with the relevant Thai Agricultural Standard: Good Agricultural Practices issued by the Ministry of Agriculture and Cooperatives of Thailand. This will build trust with smallholders and optimize the coaching outcomes, particularly in terms of language, technical specificities, and local needs.

Service providers should also translate the relevant Thai Agricultural Standard: Good Agricultural Practices issued by the Ministry of Agriculture and Cooperatives of Thailand from Thai to English.

The GPSNR GAPs consist of the following four modules:

1.     Rubber Plant Material

2. Establishment and Maintenance of Plantations

3.    Latex Harvesting

4.   Diseases and Pests

Service providers are also expected to operate in line with principles and values set forth in the GPSNR Policy Framework such as commitment to environmental protection and sustainability, zero deforestation, community engagement and FPIC etc.

The selected service provider may also be expected to work closely with the GPSNR SCB WG – Thailand National Subgroup to fine-tuned or further augment the provided coaching materials. 

 

Key Metrics

To prevent risk of false correlations, it is essential to collect baseline data on participating smallholders before the GAP coaching begins. The impact assessment should compare the participating smallholders’ data after the GAP coaching to accurately measure their improvement.

It is also important to collect control group date of smallholders who did not participate in the GAP coaching programmes to ensure any changes observed are due to the GAP coaching and not other factors. Additionally, being aware of external factors such as weather and market prices can help to better assess the results.

 The proposal should elaborate on how the following key metrics can be achieved and measured:

1.      Total number of smallholders coached

2.     Total number of trainers or coaches coached

3.     Year-by-year increase in smallholder productivity and smallholders engaged

4.    Inclusivity across gender, youth, geographic regions, and ethnicity (e.g., indigenous, or other minority communities)

5.     Monitoring and evaluation of coaching progress and outcomes

 The proposal should also identify other key metrics of importance not listed above and describe how they will be achieved and measured.

(CLOSED) Request for Proposal – Study on Human Rights and Labour Rights’ risk mapping in the global Natural Rubber value chains

Through a process led by the Strategy and Objectives Working Group the Platform has developed stated goals with a strong focus on developing a framework that supports and sustains responsible supply chain . Important among the information needed to undergo these developments of is a better understanding of the social risks including (but not limiting to) Human Rights and Labour Rights in the Natural Rubber value chains, globally.

Each country has its own governance and social structure which contributes to different social risks from country to country. While these risks are associated to the wider population, there are specific characteristics of social risks that are particularly associated to agricultural production. For the countries where law enforcement is weak, there is a risk that the workers are exposed to poor work conditions without any access to a fair complaint mechanism.

Although the initial focus of this project is on human rights and labour rights (including migrant workers), the consultant is expected to elaborate how human and labour rights are associated to other social risks (i.e. land acquisition, community health, safety and security, etc.) in order to recommend risk mitigation methods to the Strategy and Objectives Working Group.

The consultant is expected to develop generic risk profile at a global level, and specific risk profile at a regional level. The tentative regions for specific risks study are proposed as following:

  • – Production Unit and Rubber Block Processing Unit- Southeast Asia (Thailand, Indonesia, Vietnam), Africa (Cote d’Ivoire, Ghana) and Latin America (Brazil, Guatemala);
  • – Tyre Manufacturing Unit – China, Southeast Asia, Europe and US.

The list of regions above is tentative and can be adjusted upon the discussion between the consultant and the Strategy and Objectives Working Group members. After the risk profiles are developed, the consultant is expected to come up with recommendations for risk mitigation strategies for each region.

The consultant will collect the information via desktop study, interviewing of GPSNR members, research institutes, social NGOs, governmental organizations, etc. A primary list of stakeholders will be provided by the Secretariat together with the Strategy and Objectives Working Group members. A complementary list will be developed by the consultant. Regular contact and updating to the Strategy and Objective Working Group together with the Secretariat will be required. It is estimated that there will be the need for a series of face to face meetings in South East Asia over the course of the project. Travel plans shall be made by the consultant

The following submission guidelines & requirements apply to this Request for Proposal:

  1. Proposals will only be accepted from individuals or firms with experience relevant to this project.
  2. Examples of previous relevant work should be provided as well.
  3. A technical proposal must be provided that is not more than 4 pages. This technical proposal must provide an overview of the proposed solution as well as resumes of all key personnel performing the work. In addition, the technical proposal should provide a proposed schedule and milestones, as applicable.
  4. A price proposal must be provided that is not more than 1 pages. This price proposal should indicate the overall fixed price for the project as well as hourly rates and an estimated total number of days.
  5. Proposals must be signed by a representative that is authorized to commit bidder’s company.
  6. Proposals must be received prior to 10th January 2020 to be considered. Proposals should be submitted to stefano.savi@gpsnr.org for consideration.
  7. GPSNR anticipates shortlisting at least two individuals or firms to have more in-depth discussions with, and will make an award to one of these “down-selected” individuals or firms
