El Informe Especial del IPCC sobre Cambio Climático y la Tierra ¿Qué significa para América Latina?

The document examines the reciprocal relationship between climate change and land in Latin America, highlighting how land degradation and desertification threaten food security and livelihoods. It advocates for sustainable land management, gender-inclusive policies, and integrated governance to mitigate climate risks and enhance regional resilience.

• Climate change and land degradation interact in a feedback loop where climate change alters soil cover, biodiversity, and nutrient cycles, while land conditions influence regional climates. In South America, 'moisture recycling' occurs as forests release water vapor that leads to rain downwind, a process that deforestation can potentially diminish.
• Arid zones in Latin America are increasingly vulnerable to desertification, which is defined as land degradation in arid areas. In northeast Brazil, 94% of drylands are susceptible to desertification, with up to 50% already degraded due to prolonged droughts and deforestation for agriculture, threatening approximately 28 native species.
• Land degradation and climate change act as 'threat multipliers' for the most vulnerable populations, particularly women and youth. The World Bank projects a 6% reduction in the average yields of 11 major global crops in Latin America and the Caribbean by 2046–2055 compared to 1996 –2005.
• Desertification poses specific risks to energy infrastructure in Latin America. In Chile's Atacama Desert, dust deposition from intensified dust storms reduced the performance of thin-film solar modules by nearly 19% over one month of exposure.
• Sustainable land management (SLM) can provide high economic returns; a study of 363 projects found that 97% had a positive or very positive cost-benefit ratio in the long term. Effective measures include agroforestry, reducing soil erosion through reforestation, and implementing payments for ecosystem services, as seen in Costa Rica's PSA program.
• Gender inequality and insecure property rights hinder sustainable land management. Women often face greater barriers to accessing credit, agricultural advisory services, and land ownership, which limits their capacity to act as agents of sustainable change.
• Integrated governance across sectors and scales is necessary to maximize the benefits of land and water management. This includes adopting 'adaptive management' and the 'nature's contributions to people' approach to balance human needs for water, energy, and food security.
• While land-based options like bioenergy and afforestation can sequester carbon, large-scale implementation can increase competition for land, potentially harming food security and biodiversity. Therefore, reducing emissions in other sectors is vital to alleviate pressure on land.
