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 |

Environmental Rights are a Human Right to a Healthy Environment: A Brief ReviewBACKGROUND:Environmental rights constitute a legal field dedicated to protecting and preserving the environment. This area of law governs the interactions between humans and nature through a comprehensive set of regulations. The paper delves into the intrinsic link between environmental protection and human rights, highlighting the evolution and significance of environmental rights within legal frameworks. It particularly focuses on developments in the Americas and explores how environmental rights have been increasingly integrated into broader human rights agendas. Open access copy available |

Women, income and poverty: Gendered access to resources in Post-Apartheid South AfricaBackgroundThis article analyzes gendered income poverty trends in post-apartheid South Africa, focusing on the complex societal shifts that emerged during the transition from apartheid. The authors highlight how these changes have affected women’s access to resources—improving it through increased employment opportunities and hindering it due to challenges like the HIV/AIDS epidemic.
