[Consolidated Reply] Query 10: Adaptation Technologies Reaching Low-Income Communities in the Global South

Climate adaptation technologies across the Asia-Pacific region are advancing rapidly, yet their benefits remain unevenly distributed. Vulnerable populations | including low-income households, informal settlements, and smallholder farmers | face systemic barriers to accessing these solutions.

This brief draws on field-level insights from Pakistan and similar developing contexts to highlight practical challenges and policy actions required to ensure equitable, scalable, and sustainable technology adoption.

1. Case Insight: Solar Irrigation in Rural Pakistan

A notable example of climate adaptation technology deployment is the introduction of solar-powered irrigation systems in water-stressed regions of Sindh and South Punjab.

Enablers of success: Blended financing (public subsidy + donor support + farmer contribution); community engagement via NGOs and local facilitators; demonstration models showcasing economic returns; simplified and locally adaptable technology.

Key risks and constraints: High upfront costs despite subsidies; limited technical awareness among end-users; weak rural service and maintenance ecosystems; behavioural resistance to shifting from conventional diesel systems.

Local ownership mechanisms: Formation of farmer cooperatives and water user groups; cost-sharing models to ensure stakeholder commitment; training of local technicians for maintenance; peer learning and community-led adoption.

2. Persistent Barrier: Affordability and Financial Access

The most critical barrier to equitable access is limited affordability coupled with financial exclusion. Low-income communities lack access to formal credit systems, cannot meet collateral requirements, and face high perceived risk from financial institutions. Promising approaches (with partial success) include pay-as-you-go (PAYG) models for decentralized energy solutions, microfinance-linked climate technology lending, and results-based financing and targeted subsidies. Despite these innovations, scale and integration remain insufficient.

3. Role of Climate Financing Instruments

Global and regional financing mechanisms including the Green Climate Fund, Asian Development Bank, and World Bank have played a role in enabling adaptation initiatives. Success factors include-risk-sharing mechanisms attracting private investment, funding for infrastructure and pilot scaling, and support for national adaptation strategies. Limitations observed: complex and slow disbursement processes; limited accessibility for SMEs and grassroots organizations; weak last-mile delivery frameworks; policy gap where financing often prioritizes large-scale projects while underserved communities require localized, flexible funding mechanisms.

4. Determinants of Adoption and Sustainability

Successful adoption of climate technologies depends on four core factors: (1) Economic Viability: technologies must deliver clear financial benefits; (2) Contextual Relevance: solutions must align with local environmental, cultural, and technical conditions; (3) Institutional and Technical Capacity: sustainable adoption requires local technical skills, maintenance systems, and supply chain availability; (4) Community Ownership: co-designed solutions with community participation ensure long-term sustainability and trust.

5. Policy Recommendations

To bridge the climate adaptation technology gap, policymakers and stakeholders should:

A. Expand Inclusive Financing

• Develop micro-climate finance frameworks targeting low-income users
• Promote blended finance models tailored for small-scale deployment
• De-risk lending for climate technologies via guarantees and insurance

B. Strengthen Last-Mile Delivery Systems

• Support local SMEs and service providers
• Build rural maintenance and technical ecosystems
• Invest in community-based extension services

C. Simplify Access to Climate Funds

• Streamline application and disbursement processes
• Enable direct access for local organizations and intermediaries
• Introducing small-grant windows for community-led projects

D. Promote Community-Centric Design

• Institutionalize participatory planning approaches
• Integrate indigenous knowledge with modern technologies
• Support peer learning and demonstration models

E. Build Capacity and Awareness

• Provide technical training at the community-level
• Strengthen institutional capacity for implementation
• Encourage public-private partnerships for knowledge transfer

Digital Adaptation | AfCFTA’s ADAPT Initiative

ADAPT (Africa Digital Access and Public Infrastructure for Trade): Launched in 2025, now piloted in Kenya, Morocco, and Nigeria. Core features: Digital identity and “digital passports” for traders; interoperable data exchange and digitized trade documentation; stablecoin payment rails to reduce $5 billion lost annually to currency conversion costs. The impact: Could boost intra-African exports by 80% and generate $450 billion by 2035. SME relevance: Simplifies compliance, lowers transaction costs, and enables SMEs to trade across-borders without duplicating paperwork.

ADAPT was launched to solve some of the biggest barriers to intra-African trade, such as fragmented customs systems, paper-based trade documentation, slow cross-border payments, difficult verification of business identities, high compliance costs for SMEs and limited interoperability between African trade platforms.

Already in Kenya trade dynamics are emerging, such as the shift from regional to continental thinking — not just focusing on the East African Countries but connecting now with other countries such as Ghana and Egypt. Service exports are becoming more important such as those in ICT and financial services. Digital trade is the next battlefront and Kenya’s fintech innovation and already established mobile payments made it a forerunner in this program. This favors Kenya in its digital and knowledge economy.

Challenges persist such as the trade knowledge gap, logistics runaway costs, general export readiness and financing gap.

To measure ADAPT’s success: number of SMEs exporting under AfCFTA; growth in intra-African exports from Kenya; participation of women and youth-owned enterprises; adoption of digital trade infrastructure through ADAPT; and expansion of Kenyan service exports across Africa.

Adapting technology in cities in a sustainable way is a positive step toward the future. Europe is leading the way through initiatives like carbon credits and reducing carbon footprints, which shows that the world is rapidly changing in a better and more environmentally responsible direction.

I think sustainable technology in cities is one of the best changes happening right now. Europe is leading in areas like carbon credits and reducing carbon footprints, and because of that many countries are also becoming more environmentally conscious. There are many technologies helping cities become smarter and cleaner such as smart grids for saving electricity, green buildings with solar panels and rainwater harvesting, electric vehicles, smart traffic systems to reduce congestion, and waste-to-energy plants. Even concepts like vertical farming and water recycling are becoming more common in urban areas.

All these changes show that technology is not only making life easier but can also help create a more sustainable future if used properly.

For low-income communities in the Global South, and in Pakistan specifically, adaptation technologies should be affordable, locally maintainable, scalable, and resilient to climate hazards such as heatwaves, floods, droughts, water scarcity, and food insecurity.

Priority Adaptation Technologies in Pakistan: Climate-Resilient Water Management; Heat Adaptation Technologies; Climate-Smart Agriculture; Disaster Risk and Flood Management Technologies; Digital Adaptation Technologies; Nature-Based Adaptation Technologies.

The most efficient use of adaptation technologies in Pakistan is to support it with: local community ownership and capacities; access to micro and climate finance; women’s participation and entrepreneurship; integration with national disaster risk reduction plans and climate policies; and private-public partnerships for deployment.

In a climate adaptive portfolio for Pakistan, the following technologies must be prioritized: cool roofs, climate-smart agriculture, flood early-warning systems, rainwater harvesting, solar irrigation pumps, and mobile climate information systems, as they are all relevant for enhancing resilience at a low cost and can effectively reach vulnerable groups.

I would like to share an experience from Southern Thailand, where our team at Thaksin University has been working with low-income rural households to strengthen climate resilience through a community-based agricultural innovation known as the Giant Liang Model (Gnetum gnemon var. gnemon).

The adaptation technology we introduced is a low-cost propagation system called Liang Propagation Technology (LPT), which enables farmers to produce high-quality planting materials through air-layering and community nurseries. Giant Liang is a perennial indigenous crop that can be cultivated under rubber and fruit tree systems, requires relatively low water inputs, tolerates variable climatic conditions, and provides year-round harvests. These characteristics make it suitable for smallholder farmers to face increasing climate uncertainty.

What made the delivery successful was the strong partnership among local communities, community enterprises, local government agencies, and the university. Rather than transferring technology in a top-down manner, farmers participated in selecting mother plants, testing propagation techniques, establishing nurseries, and developing local markets. This participatory approach created trust and genuine local ownership.

The most persistent barrier we encountered was access to finance and market confidence. Many vulnerable households were hesitant to invest in a new crop without assurance of economic returns. To address this challenge, we established demonstration plots, farmer-to-farmer learning networks, and market linkages through community enterprises. We also promoted value-added products such as processed Liang-based foods to diversify income sources.

To date, the initiative has engaged more than 500 households across Southern Thailand and contributed to increased income opportunities through seedling production, fresh leaf sales, and value-added processing activities. More importantly, the model has enhanced community resilience by reducing dependence on a single source of income and encouraging sustainable use of local biodiversity. One lesson we have learned is that adaptation technologies succeed when they are embedded within local livelihood systems and supported by long-term capacity building, community leadership, and market development. Technology alone is not enough; social capital, financing mechanisms, and local ownership are equally important for sustainable adoption.

We welcome opportunities to collaborate and exchange experiences on climate-resilient agriculture, community-based adaptation, technology transfer, and inclusive livelihood development across the Asia-Pacific region.

We are currently seeking international partners to scale community-based climate adaptation models, develop climate-resilient food systems, and strengthen market access for vulnerable farming communities in Southeast Asia.

We would be pleased to connect with organizations, researchers, development agencies, and climate finance institutions interested in collaborative pilot projects and knowledge exchange.

It’s a huge impact on any country to adapt technologies wherein many factors need to be considered. The success factors that can be considered are to have an organization that can facilitate and promote to simplify the community to be more cooperative and can easily innovate to create a system to sustain and manage end-users. With this, many countries can keep up with others.

Presentation: UNESCAP Query 10 — Adaptation Technologies for Low-Income Communities ↗

In my view, adaptation technologies for low-income communities in the Global South must be affordable, simple, and locally adaptable. Many successful solutions are those that combine community participation with low-cost digital tools such as mobile-based early-warning systems, climate information services, and simple IoT-based monitoring for floods, rainfall, and agriculture.

Equally important is capacity building and local ownership, so that communities can maintain and use these technologies independently without high external dependency. Strengthening digital inclusion and integrating these tools with national disaster and climate systems can significantly improve resilience for vulnerable populations.

1. An Example of Effective Technology Delivery

A good case is the launch of climate information services and climate-smart farming methods in at-risk agricultural communities in Southeast Asia. The key to success was strong collaboration with local governments, extension services, and community leaders, while challenges included limited funding, technical skills, and weak local ownership. Strengthening local ownership involves engaging communities in choosing, testing, and adapting technology to fit local needs.

2. The Biggest Obstacle to Fair Technology Access

The biggest obstacle is usually not the technology itself, but rather the lack of institutional capacity and financial resources to maintain its use. Strategies that merge technology transfer with capacity building, local partnerships, and ongoing technical support have proven to be more effective than isolated technology deployments.

3. Funding Options for Technology Access

Numerous adaptation technologies have received backing from multilateral climate funds and development aid instead of commercial financing. While grants and concessional funding can kickstart adoption, long-term sustainability often relies on embedding technologies into local planning and budgets. A stronger focus on operation, maintenance, and institutional capacity would enhance long-term results.

4. Factors Influencing Long-Term Adoption

Adaptation technologies should perhaps be viewed as a sequence of adaptive actions rather than a permanent state. We change our phones every once in a while and expect farmers to stick to the same technology for long — that doesn’t seem to fit the logic. Rather than viewing technology adoption as a one-time decision followed by permanent use, adaptation technologies may be better understood as part of an evolving sequence of adaptive actions. The key question is not whether the same technology is used indefinitely, but whether communities have the capacity, resources, and institutional support to continuously adopt, adapt, replace, or upgrade technologies as risks and needs change over time.

The central challenge in extending climate adaptation technologies to low-income communities is not technological scarcity but the persistent misalignment between innovation systems and the socio-economic realities of vulnerable populations. Across many countries in the Global South, adaptation technologies already exist — climate-smart agriculture, early-warning systems, solar-powered irrigation, drought-resistant crops, digital weather advisory platforms, and decentralized water harvesting systems. Yet adoption remains uneven because technology transfer is often conceived as a technical exercise rather than a socio-institutional transformation process.

A recurring lesson from African and Asian contexts is that successful adaptation occurs when communities become co-designers rather than recipients. Technologies introduced through participatory frameworks, where local knowledge, indigenous practices, gender dynamics, and livelihood strategies are integrated into deployment models, demonstrate significantly higher rates of long-term adoption and maintenance. Ownership emerges not from training workshops alone but from meaningful involvement in problem definition, technology customization, and governance.

The most persistent barrier remains financing. Vulnerable communities face a “triple affordability challenge”: inability to pay upfront costs, limited access to credit, and high perceived investment risks by financiers. Traditional climate finance mechanisms often prioritize project-scale efficiency over distributive equity. Blended finance structures, community revolving funds, and results-based financing mechanisms have shown promise, particularly when coupled with local cooperatives and microfinance institutions that understand community risk profiles.

Equally important is institutional capacity. Many adaptation initiatives fail not because technologies are inappropriate, but because extension services, maintenance ecosystems, and knowledge support networks disappear once donor funding ends. Sustainable adoption requires moving beyond project-based interventions toward ecosystem-building approaches that strengthen local innovation capabilities, repair networks, and community-led governance structures.

Looking ahead, climate technology transfer should be evaluated not merely by the number of technologies deployed but by three deeper indicators: adaptive capacity created, resilience outcomes achieved, and equity of access ensured. The question is no longer whether adaptation technologies can reach low-income communities; it is whether our governance, financing, and innovation systems are willing to prioritize inclusion over scale and empowerment over deployment. Climate justice will ultimately be determined not by technological sophistication, but by who benefits from innovation and who remains excluded.

A few emerging adaptation technologies worth highlighting:

• AI-powered climate forecasting and early-warning systems: Analyze large volumes of weather, environmental, and historical data to predict extreme climate events and issue advance warnings, enabling governments, businesses, and communities to take preventive action and reduce risks.
• Urban digital twins: A digital model of a city integrating data on transportation, utilities, buildings, traffic, energy consumption, and public services for coordinated climate response.
• Gene-edited drought- and heat-tolerant crops: Climate-resilient agricultural varieties developed through precision genetic technologies to enhance tolerance to water scarcity and elevated temperatures, thereby improving productivity and strengthening food security.
• Precision irrigation and smart water infrastructure: Enable efficient use of water by delivering the right amount of water at the right time and place, reducing waste while improving agricultural productivity and water resource management.
• Satellite-AI monitoring: Uses satellite data and artificial intelligence to track environmental changes, predict disasters, and support the protection and sustainable management of ecosystems.
• Climate-resilient urban infrastructure: Real-time sensor networks to monitor and manage transportation, energy, water, and public services, helping cities adapt to climate change and extreme weather events.
• Integrated AI decision-support systems: Help governments and communities make informed decisions by analyzing complex data, forecasting outcomes, and providing actionable recommendations in real-time.

Across the Asia-Pacific region, climate adaptation technologies are evolving swiftly. Developing climate adaptation technologies, along with accomplishment in the Global South, is attained through changes in countries’ policies and means for solving problems. Till now, some countries are leaning towards adoption rather than waiting for technologies from the Global North. These technological adaptations and changes are aroused from various resources such as traditional technology transfer, cooperation between South-South, innovation for climate modeled technologies, development of methodologies for private financing, and speedy real-world, practical and grassroots technology deployment.

Adoption and sustainability are not determined by the technology alone, but by transformation and traditions embedded for financial, institutional, social, and knowledge systems of a country. Yet financing gaps, governance weaknesses, limited institutional capacity, and parted technology transfer pathways continue to dig out the technological gap. Partial successes across Global South could be observed, such as subsidized and government-backed solar microgrids, government-backed cooling centers, and regional cooperation platforms for farmers. Climate resilience infrastructure development needs cohesive procedures, for being beneficial and in support to low-income society and fill-up people’s knowledge gap from poor equity.

To obtain firm results, strongest programs such as providing subsidies and blended finance, aligning policies with local institutions, involving communities in co-design, and investing in training and knowledge transfer so that adaptation measures can be implemented effectively and measured over time.

When climate technologies are introduced into vulnerable or resource-constrained communities, their adoption, adaptation, and long-term sustainability are most strongly determined by four interlinked factors:

1. Affordability and Financing Models: Even low-cost technologies remain inaccessible without subsidies, concessional lending, or blended finance. Communities adopt and sustain technologies when financial mechanisms reduce upfront costs and spread risk through mechanisms such as investment insurance.
2. Institutional and Governance Support: Local governance structures and institutional capacity determine whether and how technologies are embedded into planning frameworks. Weak governance often leads to disjointed, temporary programmes without policy integration or continuity.
3. Community Ownership and Co-operational purpose: Technologies are more likely to be sustained when communities are engaged in design, deployment, and maintenance. Co-ownership builds trust, ensures cultural fit, and strengthens local stewardship.
4. Knowledge Transfer and Capacity Building: Sustained adoption depends on whether local actors have the skills to operate, maintain, and adapt technologies. The transformation is happening because renewable energy is now the fastest and cheapest path to prosperity for emerging economies with 70% of the world’s renewable potential located in the Global South.

It’s quite understandable that all these responses and highlights can help the community to advance climate adaptation technologies and strengthening including attracting source of financing especially in low developed countries to enhance the well-being of community members.

Here in Tamil Nadu many people with tetraplegia use handheld water sprinkler to reduce body warmth. They keep it closer to their hand and sprinkle the water on their head and face as when they feel hot weather.

Dear Members,

Sharing a case study on citizen science flood-monitoring under the RISE programme (Revitalising Informal Settlements and their Environments), ran across 13 informal settlements in Suva, Fiji, and Makassar, Indonesia, between 2018 and 2020 (Wolff et al., 2021).

The technology was simple: a flood gauge in each settlement, residents photographing water levels on their own phones and sharing them via WhatsApp. Over two years, 26 community members sent more than 5,300 photos.

What made it work wasn’t the tool, but what came before it. In Indonesia, the team had over a year of contact with the community before the project even began. And instead of introducing something new, they used WhatsApp, a platform people already opened every day. Ownership deepened once the exchange became two-way: in Makassar, contributors got monthly public recognition, and the same group started carrying flood warnings between residents, not just data reports back to RISE.

The barrier that nearly broke it wasn’t cost, it was continuity. In Fiji, fieldworkers were spread thinner across more settlements, and the only compensation, prepaid data top-ups, sometimes lapsed mid-week, breaking reporting habits before they could form. In Indonesia, sharing flood photos was already a habit, so uptake stayed steady. Same gauge, same app, two different outcomes — and the only real variable was whether access and familiarity held up over time.

No green bond or blended finance here, just donor and multilateral research funding (Wellcome Trust, ADB, national aid agencies). The paper is candid that long-term continuation depends on a local institutional partner, pointing to Indonesia’s disaster agencies as the realistic next home.

Dear members, many thanks for all the wonderful responses to the query. I wish to add a few points that have not come up so far.

1. SIDS and Informal Settlements

The query specifically names small island developing states (SIDS) and informal settlements, but we have not discussed this so far. According to the 2024 Lancet SIDS Report, Green Climate Fund (GCF) adaptation finance to Pacific SIDS averages around US$70 million per country, against an International Monetary Fund (IMF) estimate of roughly US$1 billion annually for Pacific SIDS alone. Across Eastern and Southeast Asia, UN-Habitat data put the number of people living in informal settlements at over 306 million. These are communities where land tenure insecurity and non-existent utility connections make most standard delivery models inapplicable.

2. On Disability and Who Participates in Co-Design

Several members have rightly stressed community participation. A 2024 Lancet Planetary Health review of over 1,600 climate adaptation studies found that just 1% considered disability. Older people and people with disabilities are often most exposed to disasters, as acting on early-warnings requires physical mobility. These are also the least likely to be present when technologies are chosen and tested. This seems worth factoring into what we mean by co-design.

3. On the Structure of Climate Finance, Not Just Its Delivery

Members have pointed to slow disbursements and funds more difficult to access. There is a more difficult problem: a 2025 joint report by Oxfam and CARE found that much of the climate finance reaching the Global South comes as loans, with some countries now repaying more than they receive. The UNEP Adaptation Gap Report 2025 notes that adaptation captures only about a third of total climate finance, with aid budgets in several major donor countries falling further. The grant-versus-loan composition of climate finance probably deserves as much attention as the disbursement process.

4. On Displacement and Those Who Cannot Move

According to data from the Internal Displacement Monitoring Centre (IDMC), Asia-Pacific recorded over 26 million climate displacements in 2023. The people hardest to reach through technology programmes are often those who cannot relocate — the elderly, people with disabilities, those without the resources that migration requires. When we discuss technology adoption and long-term maintenance, it is worth asking what happens to cooperative structures and service networks when a community is scattered by disaster.
