Philippine President Marcos has said that the creation of a 4,000-acre Silica industrial hub in New Clark City, Tarlac is part of his plan for the country to build its economy through advanced designs, semiconductors, and manufacturing.

Others were more critical of this project, saying that it creates problems for the country’s tourism industry with the way it uses water, land, and power. The government has not commented on the reported statistics about the project. The government has chosen to look into the demands of the new infrastructure on the hub.

How this decision will affect the tourists is that they will not know if there will be enough electricity and water. The Philippines has a growing infrastructure in transport with its growing mountains, agriculture landscapes, and heritage sites. Because of this, if the country plans to grow its economy in industry, it also has to plan to grow its economy in tourism.

Why Philippine Tourism Must Watch Water Use

The proposed Pax Silica hub is planned for a 1,618-hectare site within New Clark City. The development forms part of the wider Luzon Economic Corridor and is intended to support AI infrastructure, semiconductors, critical minerals and advanced manufacturing. Government officials describe it as the first AI-native industrial acceleration hub under the Pax Silica framework.

That scale naturally raises questions for Philippine tourism. Hotels, resorts, restaurants and attractions all depend on reliable water and electricity. They also compete indirectly with other industries for infrastructure capacity when destinations expand.

Claims that the hub will consume 130 million litres of water every day require caution. Public reporting has cited estimates ranging from about 65 million to 90 million litres daily. BCDA has also indicated that rainwater harvesting and impounding facilities could form part of the proposed water strategy.

The project therefore remains a planning exercise rather than an operating industrial complex. Its final water requirements will depend on the companies, technologies and facilities ultimately established at the site.

This distinction is important for responsible travel journalism. A projected requirement should not be presented as a confirmed consumption figure.

The Philippine Statistics Authority provides a useful benchmark for understanding tourism’s existing resource footprint. Tourism consumed an estimated 208.74 million cubic metres of water in 2025. Accommodation services alone accounted for 88.93 million cubic metres, or 42.6 per cent of tourism water consumption.

That figure places the Pax Silica debate in a wider context. Tourism itself is a significant resource user, particularly through accommodation. Yet tourism also depends heavily on maintaining the environmental qualities that persuade visitors to travel.

Central Luzon Already Carries Tourism Weight

Central Luzon is not an empty industrial canvas. The Department of Tourism describes the region as a destination spanning seven provinces and two highly urbanised cities. It includes Aurora, Bataan, Bulacan, Nueva Ecija, Pampanga, Tarlac, Zambales, Angeles and Olongapo.

The region combines beaches, mountains, heritage attractions, pilgrimage sites, food tourism and outdoor experiences. Clark International Airport also gives the region a growing international gateway.

Tarlac sits at the heart of this network. Its tourism offer includes Mount Pinatubo adventures, Monasterio de Tarlac, cultural attractions and expansive landscapes. Capas also serves as a gateway for visitors pursuing the Mount Pinatubo trail.

The economic backdrop is equally significant. Tarlac’s economy expanded by 7.6 per cent in 2024, according to the PSA. Services represented 49.7 per cent of the provincial economy, while the wider Central Luzon economy grew by 6.5 per cent.

This makes the development more complicated than a simple tourism-versus-industry argument.

Central Luzon needs investment, employment and modern infrastructure. At the same time, tourism needs clean landscapes, dependable utilities and strong destination identity.

The challenge is therefore capacity management rather than development alone.

Tourism Is Already A Major Economic Stake

The stakes extend beyond Tarlac. Philippine tourism generated PHP2.27 trillion in Tourism Direct Gross Value Added in 2025. That represented 8.1 per cent of national GDP.

Tourism industries employed approximately 7.70 million people, equivalent to 15.7 per cent of national employment. Domestic tourism expenditure also reached PHP3.26 trillion during the year.

These figures show why resource planning matters to the travel industry.

If infrastructure becomes more reliable, tourism can benefit from industrial development. New roads, power systems, telecommunications and accommodation capacity can improve destination access.

However, the reverse can also occur.

If industrial expansion places pressure on water, electricity, transport or environmental systems, tourism operators may face higher costs. Smaller accommodation providers could feel that pressure before larger businesses.

The potential impact can be summarised through several channels.

Clark Airport Could Gain From Industrial Growth

For travellers, the most visible positive impact could emerge through aviation.

Clark International Airport handled 2,753,101 passengers in 2025, according to its official traffic figures. Passenger traffic increased 14 per cent from 2024. International passengers reached 1.71 million, while domestic passengers exceeded 1.04 million.

That growth predates the full development of Pax Silica.

A major technology and manufacturing cluster could strengthen Clark’s position as a business gateway. Corporate travel, engineering visits, investor delegations and specialist conferences could generate additional demand.

Hotels around Clark could therefore see a different visitor mix.

Instead of relying overwhelmingly on leisure travellers, properties could attract technology executives, engineers, consultants and investors. That could support weekday occupancy and reduce dependence on traditional holiday periods.

However, increased industrial activity could also change the visitor experience.

More freight movements, construction traffic and commuter demand could affect journey times. Tourism planners will need to ensure that economic connectivity does not come at the expense of destination accessibility.

The Power Question Remains Unsettled

Electricity is another major issue, but the current public record does not support presenting a final 3-gigawatt requirement as settled fact.

The Department of Energy is reviewing the project’s power needs. Energy Secretary Sharon Garin has said several renewable-energy projects are planned for Central Luzon. She also indicated that authorities are considering requirements ranging from 50 megawatts to 5,000 megawatts.

Her key concern was that the project should not disadvantage the wider country.

That approach has direct implications for tourism.

Hotels require continuous power for air-conditioning, refrigeration, water pumps, kitchens and communications. Airports also depend on resilient energy systems. Attractions increasingly rely on digital ticketing, electronic payments and online connectivity.

Consequently, a well-designed industrial power strategy could strengthen tourism infrastructure.

A poorly balanced system could create competing demand.

The strongest solution would therefore separate new industrial demand from existing community and tourism requirements through dedicated generation, storage and grid investment.

Environmental Safeguards Will Shape Tourism Confidence

The environmental debate may ultimately prove more important than the industrial headline.

The government has repeatedly said that the Pax Silica project must comply with Philippine and international laws. BCDA has also said the project will be developed in phases.

Malacañang has separately pledged safeguards for the environment and host communities. Palace Press Officer Claire Castro said the government would not allow development to harm the environment or displace communities without appropriate measures.

Those assurances matter because tourism sells more than accommodation.

It sells landscapes, culture, biodiversity and community experiences.

For Central Luzon, this includes volcanic landscapes, mountain trails, agricultural areas and cultural sites. Tourism businesses can therefore suffer reputational damage if environmental degradation becomes associated with the region.

At present, claims that Pax Silica will automatically destroy forests or disrupt wildlife remain unproven projections. Similarly, claims of 20,000 residents being displaced have not been established in the official sources reviewed for this report.

That distinction should remain central to coverage.

Indigenous And Community Questions Need Evidence

Land and community issues nevertheless deserve sustained scrutiny.

New Clark City is being developed as a large-scale smart and resilient urban district. The Pax Silica allocation covers roughly 1,618 hectares within that broader development framework.

The government has said the site is intended to support industrial development rather than simply create another conventional factory zone.

For tourism, community participation remains crucial.

Authentic cultural tourism depends on communities retaining meaningful roles in local economies. Tourism projects also work best when residents can benefit from visitor spending without losing access to essential services.

Therefore, future assessments should examine land tenure, community consultation, employment access and environmental safeguards.

These are measurable issues.

They offer a stronger basis for evaluating tourism impacts than speculation about a predetermined number of displaced residents.

Pax Silica Could Also Create New Tourism

There is another side to the debate.

Industrial transformation does not necessarily weaken tourism. In several destinations, technology clusters have created new demand for business travel, meetings, incentives, conferences and exhibitions.

Pax Silica could potentially expand that market in Central Luzon.

The project is also attracting international investment interest. Government officials said more than 50 companies had expressed interest in the development by July. Earlier reporting had recorded at least 20 interested firms in the Luzon Economic Corridor.

That interest could support new hotels, restaurants, transport services and event venues.

The opportunity is particularly relevant because Clark already has international aviation connectivity.

A successful industrial cluster could encourage travellers to combine business trips with leisure extensions. Visitors might spend several days around Clark before exploring Tarlac, Pampanga, Subic or other Central Luzon destinations.

That would create a business-to-leisure tourism pipeline.

What Travellers Should Watch Next

Travellers visiting Central Luzon do not currently need to treat Pax Silica as an immediate tourism disruption.

The project remains in its development and planning stages. Construction will proceed in phases, while authorities continue assessing infrastructure requirements.

For visitors, the practical issues are therefore different.

Travel plans should focus on normal transport conditions, attraction operating arrangements and local weather. Travellers heading towards Mount Pinatubo should check current trail and access conditions before departure.

Visitors staying around Clark should also allow additional journey time during major construction periods as development progresses.

The wider issue is longer-term.

Travellers increasingly choose destinations based on environmental credentials. A destination that expands sustainably can strengthen its reputation. A destination that sacrifices environmental quality may eventually undermine its own tourism proposition.

A Development Test for Philippine Tourism

Pax Silica represents a major economic opportunity for the Philippines. The government wants to attract high-value investment, strengthen semiconductor capabilities and build an AI-oriented industrial ecosystem. More than 50 companies have reportedly expressed interest, while the Luzon Economic Corridor is designed to improve connectivity and investment across northern Luzon.

Yet Philippine tourism needs the same infrastructure without losing the assets that make travel valuable.

That means water planning must consider residents, agriculture, hospitality and ecosystems together. Energy planning must protect households, airports, hotels and tourism enterprises alongside new industrial demand.

Environmental assessments must also remain transparent.

The most important question is not whether the Philippines should industrialise. It is whether industrialisation can proceed while Central Luzon remains a compelling place to visit.

That balance will determine whether Pax Silica becomes a tourism asset, a tourism pressure point, or both.

Tourism Must Stay Part of Planning

The Philippines has the chance to construct a high-tech economy within an established tourism corridor on the island of Luzon. International aviation connection and the development of a visitor economy on Luzon’s Central region existing infrastructure makes them poised for investment by an entity such as Pax Silica where focus on responsible development of utility and connectivity could strengthen those areas.

The issue is if you do not focus on the creation of a tourism corridor.

Tourism accounts for 8.1% of GDP in the Philippines and offers 7.70 million jobs making it a crucial sector for growth and infrastructure development.

With further assessment and the lack of formal claims to the majority of the resources, there is potential to invest in the area and responsibly develop the eco systems and infrastructure.

If protections for the environment and ecosystems are enforced, New Clark City has the potential to be a high- technology center and a backbone of tourism in Central Luzon. Failure to do so could mean Central luzon sacrifices valuable and desired natural resources for rapid industrialization.
