Climate change affects countries worldwide, challenging economies and livelihoods. It negatively impacts food production due to temperature variability, irregular precipitation, frost, and drought, increasing pressure on agrosilvopastoral resources and reducing agricultural and livestock productivity. In Peru, the tropical dry forest, an ecosystem highly vulnerable to climate change, supports traditional goat farming, a primary livelihood for many, with a population of approximately 256,860 goats in Piura. This ecosystem is particularly sensitive to temperature and precipitation changes, which directly affect forage availability and livestock productivity. This study aimed to determine goat producers' perceptions and adaptation strategies to climate change in Marcavelica, Lancones, and La Brea. Data from 130 goat producers were analyzed using descriptive and multivariate statistics (principal component analysis, multiple correspondence analysis, and cluster analysis). Results showed that goat farming occurs predominantly in extensive systems (84.62%). Most producers (56.9%) acknowledged climate change, perceiving changes in temperature (69.9%), precipitation patterns (100%), soil productivity (79.2%), and water availability (50%). Four producer clusters were identified based on adaptive capacity: excellent (6.16%), good (23.08%), regular (75.38%), and poor (24.62%). Producers with higher education, associativity, and training demonstrated better knowledge and adaptive capacity. Climate change is evident in the dry forest ecosystem, negatively affecting goat farming. These findings underscore the importance of education, technical support, and associativity to enhance producers' resilience and sustain livestock production under climate variability.

Increasing drought pressure under anthropogenic climate change may jeopardize the potential of tropical forests to capture carbon in woody biomass and act as a long-term carbon dioxide sink. To evaluate this risk, we assessed drought impacts in 483 tree-ring chronologies from across the tropics and found an overall modest stem growth decline (2.5% with a 95% confidence interval of 2.2 to 2.7%) during the 10% driest years since 1930. Stem growth declines exceeded 10% in 25% of cases and were larger at hotter and drier sites and for gymnosperms compared with angiosperms. Growth declines generally did not outlast drought years and were partially mitigated by growth stimulation in wet years. Thus, pantropical forest carbon sequestration through stem growth has hitherto shown drought resilience that may, however, diminish under future climate change.

Climate change is one of the main global challenges, addressed in the United Nations Sustainable Development Goal (SDG) 13, which seeks to "take urgent action to combat climate change and its impacts". The objective of the research was to analyze scientific articles that directly relate to SDG 13 through a bibliometric analysis for the period 2015 to 2024 of the Scopus database using the search term “SDG 13” OR “Sustainable Development Goal 13”. The research identified prolific authors, articles, sources with the highest impact in the area of study, leading institutions and countries in publications along with a detailed keyword analysis. The results show that interest in the study of SDG 13 has grown significantly with a focus on areas such as mitigation and adaptation, low carbon economy and public policy. This analysis provides an overview of advances in SDG 13 research, helps to identify knowledge gaps and emerging areas, and contributes to the formulation of effective policies and the drive for global climate action.
