During the past decade there has been a growing interest in bioenergy, driven by concerns about global climate change, growing energy demand, and depleting fossil fuel reserves. The predicted rise in biofuel demand makes it important to understand the potential consequences of expanding biofuel cultivation. A systematic review was conducted on the biodiversity impacts of three first-generation biofuel crops (oil palm, soybean, and jatropha) in the tropics. The study focused on the impacts on species richness, abundance (total number of individuals or occurrences), community composition, and ecosystem functions related to species richness and community composition.

The environmental impacts of palm oil production have been in the spotlight for many years. Opinions abound about the impacts of oil palm plantations on biodiversity and ecosystem function, but how many of these are supported by research and to what extent are policies and practice informed by science? This Info Brief summarizes a systematic review of the scientific evidence and highlights some of the findings of immediate interest to policy and research communities.

Oil palm plantations and smallholdings are expanding massively in Indonesia. Proponents highlight the potential for job creation and poverty alleviation, but scholars are more cautious, noting that social impacts of oil palm are not well understood. This report draws upon primary research in West Kalimantan to explore the gendered dynamics of oil palm among smallholders and plantation workers. It concludes that the social and economic benefits of oil palm are real, but restricted to particular social groups. Among smallholders in the research area, couples who were able to sustain diverse farming systems and add oil palm to their repertoire benefited more than transmigrants, who had to survive on limited incomes from a 2-ha plot.

Biofuels, or fuels derived from transformation of biological matter, are hailed by some as a promising source of renewable energy potentially reducing greenhouse gas emissions. A widespread adoption of biofuels will however present its own set of challenges and consequences. Direct or indirect land use change due to expansion of feedstock cultivation can cause deforestation and forest degradation leading to biodiversity losses and other environmental concerns like soil degradation and erosion, water pollution and scarcity, and the risk of crop species invading natural ecosystems. Although biofuel production is currently not the main use of palm oil and soybean and hence, has so far contributed only little to the land-use change patterns, it has been predicted to grow. Therefore, it is important to know the potential consequences of the expansion of biofuel cultivation may have for biodiversity in order to provide policy guidance.

There is abundant literature focusing on the palm oil sector, which has grown into a vigorous sector with production originating mainly from Malaysia and Indonesia, and on increased palm oil consumption in many countries around the globe, particularly European Union states, China and India. This sector expansion has become quite controversial, because while it has negative social and environmental impacts, it also leads to positive benefits in generating fiscal earnings for producing countries and regular income streams for a large number of large- and small-scale growers involved in palm oil production. This document reviews how the social, ecological, and environmental dynamics and associated implications of the global palm oil sector have grown in complexity over time, and examines the policy and institutional factors affecting the sector's development at the global and national levels. This work examines the geographies of production, consumption and trade of palm oil and its derivatives, and describes the structure of the global palm oil value chain, with special emphasis on Malaysia and Indonesia. In addition, this work reviews the main socioenvironmental impacts and trade-offs associated with the palm oil sector's expansion, with a primary focus on Indonesia. The main interest is on the social impacts this has on local populations, smallholders and workers, as well as the environmental impacts on deforestation and their associated effects on carbon emissions and biodiversity loss. Finally, the growing complexity of the global oil palm value chain has also driven diverse types of developments in the complex oil palm policy regime governing the sector's expansion. This work assesses the main features of this emerging policy regime involving public and private actors, with emphasis on Indonesia. There are multiple efforts supporting the transition to a more sustainable palm oil production; yet the lack of a coordinated public policy, effective incentives and consistent enforcement is clear and obvious. The emergence of numerous privately driven initiatives with greater involvement of civil society organizations brings new opportunities for enhancing the sector's governance; yet the uptake of voluntary standards remains slow, and any push for the adoption of more stringent standards may only widen the gap between large corporations and medium- and smallscale growers. Greater harmonization between voluntary and mandatory standards, as well as among private initiatives is required. Commitments to deforestation-free supply chains have the potential to reduce undesired environmental impacts from oil palm expansion, and while this risks excluding smallholders from the supply chains, such commitments may function to leverage the upgrading of smallholder production systems. Their success, however, will require greater public and private sector collaboration.

The book provides a broad synthesis of the major supply and demand drivers of the dramatic expansion of oil crops in the tropics; its economic, social, and environmental impacts; and the future outlook to 2050. It is a comprehensive review of the oil crop sector with a major focus on oil palm and soybeans, the two most dynamic crops in world agriculture in recent decades.
