The cacao trade and export industry has been impacted by cadmium (Cd2+) accumulation in soils, as the metal is absorbed by plants and transferred to the tissues. Consequently, cacao beans and their derivatives can become contaminated, sometimes exceeding permissible limits. In this study, the capacity of native Trichoderma strains to reduce Cd accumulation in cacao was evaluated. Twelve Trichoderma strains were analyzed to assess their cadmium removal capacity through in vitro assays and their ability to reduce Cd concentration in cacao plants under controlled in vivo conditions. The in vitro results showed that several Trichoderma strains could remove cadmium and accumulate it in their biomass. However, this process is complex as it depends on metal concentration and environmental conditions. Notably, T. afroharzianum UCF18-M1 and CP24-6 exhibited high removal efficiencies at 100 ppm (61.79 ± 2.98% and 57.93 ± 4.14%, respectively). In contrast, the in vivo assays revealed that, contrary to expectations, some strains—including those with the highest removal efficiency—stimulated Cd uptake in plants, even at toxic levels, such as T. orientale BLPF1-C1. However, T. longibrachiatum UCF17-M4 and Trichoderma sp. UCPF2-C1 significantly reduced Cd accumulation in the stem. These findings highlight the potential of these strains to mitigate Cd contamination in cacao.
Regenerative agriculture: Inclusive approach for transforming conventional agriculture
(Springer Nature, 2024-12-21) Chatterjee, Subhrajyoti; Nayak, Pritismita; Acharya, Sumit; Arockia Infant Paul, R; Ocaña Reyes, Jimmy Alcides
Regenerative agriculture is an inclusive and transformative approach that aims to revolutionize conventional farming practices. It goes beyond the traditional boundaries of agriculture by focusing on restoring ecosystems, improving soil health, and promoting a sustainable coexistence between humans and the environment. This chapter explores the core principles of regenerative agriculture, highlighting its potential to address pressing environmental challenges associated with conventional methods. Key components include prioritizing soil health through practices like cover cropping and minimizing soil disturbance, promoting biodiversity through diversified crops and holistic management, and implementing water conservation techniques. The economic viability of regenerative practices is supported by reduced input costs, increased resilience, and diversified income streams for farmers. Socially, regenerative agriculture encourages community engagement and knowledge sharing and contributes to local food security. Although there are barriers to adopting regenerative practices, such as initial transition costs and policy challenges, many farmers have already embraced this approach. As emerging trends and technologies continue to shape the agricultural landscape, regenerative practices offer a beacon of hope for a more sustainable and inclusive future. They provide a pathway towards resilient, environmentally conscious, and socially equitable food systems.

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.
