18.3 Climate Change and Environmental Politics

Climate change hits Latin America hard, worsening inequalities and threatening livelihoods. Rising seas, more disasters, and changing weather patterns affect agriculture, fishing, and vulnerable communities. Some countries are taking action, while others prioritize economic growth over environmental concerns.

Regional cooperation is key in tackling climate issues. Organizations like CELAC and UNASUR promote joint strategies and knowledge-sharing. Countries like Costa Rica and Uruguay lead in renewable energy, setting ambitious targets for a greener future.

• Latin America is highly vulnerable to the impacts of climate change including rising sea levels (coastal flooding), more frequent and intense natural disasters (hurricanes, droughts), and changes in precipitation patterns affecting agriculture and water resources
• Climate change exacerbates existing socio-economic inequalities and disproportionately affects marginalized communities such as indigenous populations (loss of traditional livelihoods) and the rural poor (food insecurity, displacement)
• Many Latin American countries are heavily dependent on natural resources such as agriculture (coffee, bananas), forestry (timber), and fishing (shrimp, tuna), which are particularly sensitive to the effects of climate change
  • Droughts and changing rainfall patterns can lead to crop failures and reduced agricultural productivity
  • Rising sea temperatures and ocean acidification can disrupt marine ecosystems and fisheries

Political Responses and Regional Cooperation

• Political responses to climate change in Latin America vary, with some countries taking proactive measures to reduce greenhouse gas emissions (carbon taxes, renewable energy targets) and adapt to the impacts (early warning systems, infrastructure resilience), while others prioritize economic development over environmental concerns
• Regional organizations such as the Community of Latin American and Caribbean States (CELAC) and the Union of South American Nations (UNASUR) have developed joint strategies and action plans to address climate change
  • These initiatives aim to promote regional cooperation, knowledge-sharing, and capacity-building on climate change mitigation and adaptation
• Some Latin American countries such as Costa Rica (99% renewable electricity) and Uruguay (95% renewable electricity) have emerged as global leaders in renewable energy and sustainable development, setting ambitious targets for decarbonization and green growth

Policy Effectiveness for Climate Change

National Strategies and Implementation Challenges

• Many Latin American countries have developed national climate change strategies and action plans, outlining their commitments to reduce greenhouse gas emissions (Nationally Determined Contributions under the Paris Agreement) and adapt to the impacts of climate change
• The effectiveness of these policies depends on factors such as political will (leadership, public support), institutional capacity (technical expertise, coordination), financial resources (international aid, private investment), and public support (awareness, participation)
• Some countries have implemented successful policies to promote renewable energy such as Brazil's ethanol program (sugarcane-based biofuel) and Chile's solar energy initiatives (Atacama Desert), reducing their dependence on fossil fuels
• Other countries have focused on adaptation measures such as improving infrastructure resilience (flood barriers, drainage systems), developing early warning systems for natural disasters (drought monitoring, hurricane forecasting), and promoting sustainable land-use practices (agroforestry, soil conservation)
  • These measures aim to reduce the vulnerability of communities and ecosystems to the impacts of climate change

Regional Cooperation and Knowledge-Sharing

• Regional cooperation and knowledge-sharing have been important in developing and implementing effective climate change policies, with initiatives such as the Latin American Network on Climate Change (LANET) facilitating collaboration among countries
  • LANET promotes the exchange of best practices, technical expertise, and scientific knowledge on climate change mitigation and adaptation
• However, many Latin American countries still face significant challenges in implementing their climate change policies including limited financial resources (high upfront costs, competing priorities), weak institutional frameworks (lack of coordination, enforcement), and competing development priorities (poverty reduction, economic growth)
  • These challenges can hinder the effectiveness of climate change policies and require sustained political commitment and international support to overcome

Environmental Activism and Sustainability

Indigenous Communities and Social Movements

• Environmental movements and activism have played a significant role in raising awareness about environmental issues and pressuring governments to take action on sustainability in Latin America
• Indigenous communities have been at the forefront of environmental activism, defending their ancestral lands and resources against extractive industries (mining, oil drilling) and large-scale development projects (hydroelectric dams, agribusiness)
  • The Waorani people in Ecuador successfully sued the government to stop oil drilling in their territory, setting a legal precedent for indigenous land rights
• Social movements such as the Landless Workers' Movement (MST) in Brazil and the Mapuche movement in Chile have mobilized to demand land rights and environmental justice
  • The MST has occupied and cultivated unused land to promote agrarian reform and sustainable agriculture, while the Mapuche have resisted the expansion of forestry plantations and hydroelectric projects in their ancestral territories

NGOs, Civil Society, and Challenges

• NGOs and civil society organizations have been instrumental in advocating for stronger environmental regulations, monitoring compliance, and promoting sustainable development practices
  • Organizations such as Greenpeace (campaign against deforestation in the Amazon) and the World Wildlife Fund (conservation of biodiversity hotspots) have raised international awareness and support for environmental issues in Latin America
• Environmental activism has often been met with repression and violence, with many activists facing threats, intimidation, and even assassination for their work
  • In 2016, Honduran activist Berta Cáceres was murdered for her opposition to a hydroelectric dam project, highlighting the risks faced by environmental defenders in the region
• Despite these challenges, environmental movements have achieved significant victories such as the recognition of the rights of nature in the constitutions of Ecuador and Bolivia (legal personhood for ecosystems), and the cancellation of large-scale mining and hydroelectric projects (Conga mine in Peru, Belo Monte dam in Brazil)
  • These victories demonstrate the power of grassroots activism and public pressure in shaping the political agenda on sustainability in Latin America

Green Growth and Low-Carbon Transition in Latin America

Renewable Energy Potential and Progress

• Latin America has significant potential for green growth and the transition to a low-carbon economy, given its abundant renewable energy resources such as solar (Atacama Desert), wind (Patagonia), and hydropower (Amazon basin)
• Some countries such as Costa Rica (99% renewable electricity) and Uruguay (95% renewable electricity) have already made significant progress in decarbonizing their economies, with high shares of renewable energy in their electricity mix and ambitious targets for carbon neutrality
  • Costa Rica aims to become the world's first carbon-neutral country by 2050, through a combination of renewable energy, electric transport, and forest conservation
• Other countries such as Brazil (biofuels) and Mexico (geothermal) have developed national strategies for low-carbon development, focusing on sectors such as agriculture, forestry, and transport
  • Brazil's ethanol program has reduced the country's dependence on fossil fuels and created a thriving biofuel industry, while Mexico's geothermal resources provide a stable source of renewable energy

Economic Opportunities and Challenges

• The transition to a low-carbon economy can create new economic opportunities such as jobs in renewable energy (solar panel installation, wind turbine manufacturing), sustainable agriculture (organic farming, agroforestry), and eco-tourism (nature reserves, sustainable lodging)
  • In Brazil, the ethanol industry has created over 1 million jobs and generated billions of dollars in revenue, demonstrating the economic benefits of green growth
• However, the transition also faces significant challenges including the need for large-scale investments in infrastructure and technology (electric grids, charging stations), the resistance of entrenched fossil fuel interests (oil and gas lobbies), and the social and economic impacts on communities dependent on carbon-intensive industries (coal mining, oil extraction)
  • In Ecuador, the government's decision to allow oil drilling in the Yasuní National Park, a biodiversity hotspot and home to indigenous communities, highlights the tensions between economic development and environmental protection
• International cooperation and support such as through the Green Climate Fund (multilateral financing mechanism) and other multilateral initiatives can play an important role in facilitating the transition to a low-carbon economy in Latin America
  • The Inter-American Development Bank has provided over $5 billion in financing for renewable energy and energy efficiency projects in the region, supporting the deployment of clean technologies and the creation of green jobs
