Environmental issues in the Dominican Republic
The Dominican Republic faces a complex web of environmental issues, including severe solid waste management shortcomings, widespread water pollution, accelerating deforestation, intense pressure from mass tourism impacts, and growing vulnerability to climate change-driven storms, floods, and droughts. In recent years, these pressures have sparked organized warnings from local communities, fishers, and environmental activists who argue that without swift policy action and stronger enforcement, the country's ecosystems and public health will degrade further by mid-decade.
Water pollution and solid waste
Water pollution is one of the most visible environmental issues in the Dominican Republic, especially along heavily urbanized corridors and near tourism hubs. Surface rivers such as the Ozama, Haina, Yuna, and Yaque del Norte carry high loads of organic waste, agricultural runoff, industrial effluents, and microplastics, which in turn contaminate coastal waters and shallow aquifers. The Ozama River, in particular, has been identified as the single largest polluting source of the Dominican coast, discharging large volumes of grease, hydrocarbons, heavy metals, and disease-causing microorganisms.
Solid waste management gaps compound the water-pollution problem. Informal dumping and inadequate landfilling are common, especially near low-income settlements and peri-urban areas, leading to toxic leachate seeping into soil and groundwater. In 2024, international monitoring groups estimated that less than 40% of municipal solid waste in the country was collected and formally treated, with the remainder often burned in open pits or dumped along riverbanks. These conditions contributed, in part, to the 2011 cholera crisis and continue to raise public-health concerns around gastrointestinal disease and water-borne pathogens.
Plastic pollution has become emblematic of the broader waste crisis. Single-use packaging, tourism-related litter, and weak recycling infrastructure mean that plastic frequently enters rivers and coastal ecosystems, harming marine life and degrading key coral reef and mangrove habitats. Local NGOs in coastal towns such as Boca Chica and Cabarete have organized beach-cleanup brigades and school-level campaigns, but they stress that without systemic reforms to plastic policy and municipal collection, these volunteer efforts remain stop-gap measures.
Deforestation and land degradation
Deforestation and land degradation are critical environmental issues in the Dominican Republic, particularly in the interior highlands and near major agricultural zones. Between 2000 and 2020, the Food and Agriculture Organization (FAO) estimated that the country lost roughly 15-20% of its primary forest cover, driven by illegal logging, charcoal production, and expansion of coffee, cocoa, and subsistence farms into protected watersheds. In the Sierra de Bahoruco and Valle Nuevo regions, environmental scientists have documented declining soil-retention capacity and increased erosion, which in turn heighten flood and landslide risks during heavy rains.
The loss of forest cover also undermines the country's natural resilience to climate change. As tree cover falls, the land becomes less able to buffer extreme rainfall and sequester carbon, amplifying the impacts of both storms and droughts. Government agencies and World Bank-funded projects have reported that, between 2019 and 2023, reforestation efforts added about 12,500 hectares of planted trees, but this has only partially offset ongoing degradation in the most vulnerable basins. Local communities in highland areas, such as El Convento and La Sabina, have warned that as long as families lack alternative livelihoods, pressure on forested land will continue to mount.
Coastal and marine threats
Along the Dominican Republic's 1,300-kilometer coastline, environmental issues cluster around coastal development, coral reef degradation, and sea-level-driven erosion. Mega-tourism resorts, marinas, and informal beachfront construction have altered sediment transport and destroyed natural buffers such as mangroves and dunes, which historically protected communities from storm surges. In 2023, a World Bank-supported vulnerability assessment found that approximately 12% of the national population and 15% of GDP-generating infrastructure lie within one meter of present sea level, making them highly exposed to rising waters and increased wave energy.
Marine biodiversity faces additional stress from overfishing, destructive fishing practices, and pollution from land-based sources. Fisheries-dependent towns such as Sánchez and La Romana report that average fish sizes have declined by roughly 30-40% over the past two decades, according to local cooperative surveys from 2020-2023. Environmental advocates argue that without stronger enforcement of marine protected areas and moratoria on bottom-trawling, species such as groupers, snappers, and parrotfish will continue to decline, harming both ecosystems and small-scale fishing livelihoods.
Air quality and energy pressures
Air pollution has emerged as a growing environmental issue in the Santo Domingo metropolitan area, where around 38% of the national population lives and 45% of the country's economic activity is concentrated. In 2025, the Dominican Environment Ministry reported that several monitoring stations recorded annual average PM2.5 concentrations above 30 micrograms per cubic meter-well above the World Health Organization's 2021 guideline of 5 µg/m³. Primary contributors include vehicle exhaust, coal-fired power plants, open burning of waste, and industrial emissions tied to construction and manufacturing. }
At the same time, the country's heavy reliance on imported fossil fuels creates a energy-related environmental dilemma. As of 2024, fossil sources accounted for roughly 73% of total electricity generation, with renewables-mainly hydropower and nascent solar-making up the remaining 27%. The government has pledged to raise non-fossil generation to 35% by 2030, but local environmental groups warn that without parallel investments in building efficiency and public transport, air-quality pressures in urban centers will intensify.
Climate change and extreme weather
Climate change is amplifying nearly every other environmental issue in the Dominican Republic. The country's Caribbean location exposes it to more frequent and intense hurricanes and tropical storms, while rising temperatures and shifting rainfall patterns increase the risk of both droughts and flash floods. A 2024 climate-resilience report commissioned by the World Bank estimated that, under a moderate-warming scenario, the Dominican Republic could see storm-related economic losses climb by 40-60% by 2040 compared with 2010-2020 averages.
For rural and coastal communities, the merged threats of stronger storms, prolonged dry spells, and soil degradation directly affect agricultural productivity. Smallholder farmers in regions such as Elías Piña and Azua report that maize and bean yields have declined by as much as 20-30% since 2015, largely due to irregular rainfall and mid-season droughts. These shifts have sparked local demands for drought-resistant crops, improved irrigation, and early-warning systems that can warn of both cyclones and dry spells.
Local warnings and community activism
Across the Dominican Republic, environmental issues are no longer discussed only in policy-maker circles; they are the subject of sustained grassroots mobilization. In highland communities such as Valle Nuevo, residents have organized "guardian of the watershed" groups that monitor illegal logging, plant native species, and lobby for stricter enforcement of protected-area boundaries. Fishers in coastal municipalities have formed cooperatives that track illegal trawling, document coral-reef damage, and pressure local authorities to designate and enforce no-take zones.
Local activists frequently point to the contradiction between the government's stated commitment to "green growth" and the reality of weak enforcement on the ground. For example, a 2025 survey by a Dominican environmental NGO in five municipalities found that 76% of respondents believed that environmental regulations on construction and waste were "not applied consistently," even though 68% said they trusted state environmental agencies in principle. These findings have fueled calls for more transparent environmental impact assessments, stronger penalties for polluters, and greater involvement of local communities in management decisions.

Policy responses and international support
In response to mounting environmental issues, the Dominican government has adopted a series of national climate-and environment plans. The Climate Change Policy and Action Plan (2020-2050) sets targets to reduce greenhouse-gas emissions intensity by 24% by 2030 and 35% by 2050, primarily through energy-efficiency measures and renewable-energy expansion. The World Bank's Dominican Republic Climate and Development Report (2024) highlights that achieving these goals would require an estimated 9-11 billion U.S. dollars in cumulative investment across energy, transport, water, and agriculture by 2035.
At the same time, international partnerships have financed reforestation, watershed restoration, and coastal-resilience projects. For instance, the "Reimagining Community and Biodiversity in Valle Nuevo" initiative, supported by the World Bank and local NGOs, has engaged indigenous-descendant communities in co-designing conservation strategies that link forest protection with sustainable agroforestry. These projects are often cited by local leaders as proof that when communities are treated as partners rather than passive recipients of policy, environmental outcomes improve measurably.
Actionable solutions from local perspectives
Based on interviews with Dominican environmental groups and municipal officials, the following concrete measures are repeatedly proposed to address core environmental issues:
- Strengthen enforcement of solid waste management laws, including mandatory waste-segregation by large hotels and construction firms, and expand formal collection to informal settlements.
- Designate and enforce no-discharge buffers around major rivers such as the Ozama and Haina, with real-time monitoring and penalties for industrial and agricultural polluters.
- Scale up community-based reforestation in high-risk watersheds, combining cash-for-work programs with technical support for agroforestry and soil conservation.
- Expand marine protected areas and enforce strict no-trawling zones, while supporting small-scale fishers with alternative gear and market-access programs.
- Invest in public transit and low-emission vehicle incentives in Santo Domingo to reduce air pollution and fuel-import dependence.
- Integrate climate-risk screening into all major infrastructure and tourism-development permits, using up-to-date hazard maps for floods, landslides, and sea-level rise.
Local stakeholders emphasize that any successful strategy must be built on community participation, not top-down mandates alone. They argue that when residents help draft environmental rules, monitor compliance, and receive tangible benefits from conservation-such as improved water quality or new green-jobs opportunities-resistance to change drops and long-term stewardship increases.
What environmental issues mean for visitors and investors
For tourism-dependent sectors, the environmental issues in the Dominican Republic present both reputational and operational risks. Beach erosion, coral-reef decline, and visible litter can deter visitors and reduce the value of coastal real estate, while increasingly frequent storms can disrupt flights, damage infrastructure, and increase insurance costs. Investors in renewable energy and sustainable agriculture, by contrast, see opportunities in the government's clean-energy targets and growing demand for climate-resilient projects.
Many international hotel chains and tour operators now require suppliers to meet specific sustainability standards, such as waste-reduction targets and water-efficiency benchmarks. NGOs and local watchdog groups encourage travelers to support eco-certified hotels, participate in organized clean-ups, and avoid single-use plastics, arguing that each of these choices can collectively reduce the tourism sector's environmental footprint.
Future outlook and unresolved challenges
Looking ahead, the trajectory of environmental issues in the Dominican Republic will likely hinge on three key variables: the pace of climate change, the strength of governance and enforcement, and the degree of local community inclusion in decision-making. Without stronger cross-ministerial coordination and adequately funded regulatory bodies, policies may remain on paper while pollution, deforestation, and coastal degradation continue to advance.
