Environmental and social impacts of oil palm plantations and their implications for biofuel production in Indonesia

This paper reviews the development of oil palm with linkages to biofuel in Indonesia and analyzes the associated environmental and socioeconomic impacts. We selected three plantation study sites in West Papua (Manokwari), West Kalimantan (Kubu Raya), and Papua (Boven Digoel) to assess the impacts. Research findings indicate that the development of oil palm in all three sites has caused deforestation, resulting in significant secondary external impacts such as water pollution, soil erosion, and air pollution. In terms of social impacts, many stakeholder groups, i.e., employees, out-growers, and investing households, report significant gains. However, we found these benefits were not evenly distributed. Other stakeholders, particularly traditional landowners, experienced restrictions on traditional land use rights and land losses. We observed increasing land scarcity, rising land prices, and conflicts over land in all sites. Three major trade-offs are associated with the development of oil palm plantations, including those related to biofuels: unevenly distributed economic benefits are generated at the cost of significant environmental losses; there are some winners but also many losers; and economic gains accrue at the expense of weak rule of law. To reduce the negative impacts and trade-offs of oil palm plantations and maximize their economic potential, government decision makers need to restrict the use of forested land for plantation development, enforce existing regulations on concession allocation and environmental management, improve monitoring of labor practices, recognize traditional land use rights, and make land transfer agreements involving customary land more transparent and legally binding.

Role of exposure in adoption and intensity of tree planting practices among smallholder households in Rwanda

Agroforestry is widely promoted across Sub-Saharan Africa as a strategy for restoring degraded landscapes and enhancing livelihoods, with strong potential to support Sustainable Development Goals (SDGs)—especially SDG 15 (Life on Land) and SDG 2 (Zero Hunger). However, despite significant investments in agroforestry initiatives, there is limited evidence on their effectiveness in driving adoption at scale. This study employs the augmented inverse probability weighting method to assess how exposure to agroforestry practices influences tree planting adoption and intensity, using panel household data from Eastern Rwanda. Findings indicate that exposure increased adoption probability by 7% (p = 0.03). Households exposed both before and after the baseline period demonstrated a higher adoption probability (15%, p = 0.01), suggesting that cumulative exposure has a lasting impact. While exposure modestly improved tree diversity and increased the number of trees in cropping fields, farmers primarily adopted exotic species over indigenous ones. Moreover, the study found that male household exposure correlated with higher adoption probability and greater tree numbers, and seedling provision positively influenced tree numbers and species diversity among adopters. The findings highlight the importance of sustained farmer engagement, targeted gender-sensitive interventions, and structured training programs. Additionally, policies should prioritize seedling availability and establish an enabling policy environment to maximize adoption and agroforestry impact.

COVID-19 pandemic exacerbated food insecurity in South American countries

The COVID-19 pandemic had unprecedented political, economic, and social consequences, intensifying global food insecurity (FI). To assess its impact on different socio-economic groups, this study analyzed food insecurity prevalence and severity across 18,997 households in seven South American countries using the Food Insecurity Experience Scale (FAO). Findings indicate that before the pandemic, 4.5% of households experienced Moderate FI, while 0.6% faced Severe FI. During the pandemic, Moderate FI surged to 16.9% (+12.4%), and Severe FI rose to 2.7% (+2.1%). Venezuela had the highest pre-pandemic Moderate FI prevalence (9.7%), while Peru reported the most Severe FI cases (1.1%). Peru saw the largest increase in both Moderate FI (+23.9%) and Severe FI (+4.6%). Low-income households (earning <2 minimum wages per month) were most vulnerable. Uruguayan low-income families experienced the sharpest increase (+40.4%) in Moderate FI, while Peru’s low-income households saw Severe FI rise by +9.1%. This study highlights the profound and far-reaching effects of COVID-19 on food insecurity in South America, stressing the urgent need for effective public policy interventions to enhance resilience against future crises. Policymakers must develop targeted strategies to address immediate challenges and build a sustainable, resilient food security landscape for the region.
