The 10 Elements of Agroecology: enabling transitions towards sustainable agriculture and food systems through visual narrativesBackgroundAgriculture and food systems around the world are failing to deliver the desired outcomes for food security and nutrition, creating an urgent need for transformative change to meet the Sustainable Development Goals (SDGs) by 2030. Addressing this challenge requires stakeholders to adopt holistic approaches that integrate population, diet, and food production, moving beyond a narrow focus on technological advancements and productivity. Agroecology, which incorporates social, political, and economic dimensions, provides a promising pathway to build sustainable and equitable food systems. Open access copy available |
The contradiction of the sustainable development goals: Growth versus ecology on a finite planetBackgroundThe Sustainable Development Goals (SDGs), adopted by the United Nations in 2015, promote a holistic vision of development that recognizes the interconnectedness of poverty, underdevelopment, and environmental concerns. Comprising 17 goals and 169 specific targets, the SDGs reflect a shift in development theory, emphasizing that human flourishing depends on addressing ecological degradation. However, the framework reveals a fundamental contradiction. Goals 6, 12, 13, 14, and 15 advocate for environmental protection and “harmony with nature,” while Goal 8 emphasizes the pursuit of continued global economic growth.

Climate Risk ManagementBACKGROUND:Worldwide efforts are underway to devise and apply strategies to manage these risks effectively. Key challenges in climate risk management include the integration of necessary scientific disciplines, articulating stakeholder values and objectives, and quantifying pivotal uncertainties and trade-offs, all of which are vital for crafting effective management strategies. The paper addresses the intensification of global climate risks driven by accelerating climate change. The authors review these challenges based on existing literature to identify potential avenues to overcome them. Open access copy available |
Advances and shortfalls in applying best practices to global tree‐growing effortsBACKGROUND:Over the past three decades, there has been a rapid increase in the number of organizations engaged in tree planting to meet international targets exceeding a trillion trees. These initiatives aim to sequester carbon, conserve biodiversity, enhance water quality, and reduce social inequity. Despite these goals, frequent failures and unintended ecological and social impacts have led to the creation of numerous best practice guidelines for reforestation. Open access copy available |
Livelihoods, Forests, and Conservation in Developing Countries: An OverviewBACKGROUND:Poverty is a huge challenge, with 2.8 billion of the world’s 6 billion people living on less than $2 a day. The paper highlights the alarming extent of poverty in developing countries and addresses the rapid deforestation, which compromises ecological integrity and exacerbates social inequities. The authors focus on exploring whether poverty alleviation and forest conservation can be aligned as complementary rather than conflicting objectives. Available with subscription or purchase |
Alnus acuminata: Valuable Timber Tree for Tropical HighlandsBackgroundAlnus acuminata, also known as alder, is a nitrogen-fixing tree native to tropical highlands from Mexico to northern Argentina. It thrives in elevations between 1,200 and 3,200 meters, with annual rainfall of 1,000 to 3,000 mm and temperatures ranging from 4°C to 27°C. This species plays a significant role in watershed protection, soil enrichment, and sustainable timber production. Its adaptability to moist soils, including riverbanks and landslides, and its resilience in disturbed areas make it a valuable pioneer species. Farmers in regions like Costa Rica have used Alnus acuminata in agroforestry systems for over 90 years, integrating it with pastureland and coffee cultivation. Open access copy available |
Evaluating alder-endophyte (Alnus acuminata-Frankia-Mycorrhizae) interactionsBackgroundThe study examines the interactions between Alnus acuminata (a nitrogen-fixing tree), Frankia (a nitrogen-fixing actinomycete), and vesicular-arbuscular mycorrhizae (VAM), specifically Glomus intra-radices. These symbiotic relationships are significant in upland areas of Costa Rica, Colombia, and Venezuela, where A. acuminata grows alongside pastures. Frankia forms root nodules that fix atmospheric nitrogen, while VAM enhances phosphorus uptake, crucial for plant growth in nutrient-poor soils. The study aims to understand the effects of these interactions on nitrogen fixation and seedling development under varying phosphorus levels. Available with subscription or purchase |
Erythrina (Leguminosae: Papilionoideae): A Versatile Genus for Agroforestry Systems in the Tropics.BackgroundThe genus Erythrina (Leguminosae) plays a crucial role in tropical agroforestry systems. These trees are adaptable and widely distributed in tropical and subtropical regions, with over 100 species globally. Erythrina species are known for their rapid growth, nitrogen-fixing capability, and adaptability to various environments, including low-fertility soils. Historically, they have been integrated into agricultural systems as shade trees, live fences, and forage sources. The diverse ecological benefits of Erythrina highlight its importance in addressing food security, environmental conservation, and rural livelihoods in tropical regions. Open access copy available |
