Resumen

La industria brasileña de la caña de azúcar viene se ampliando desde el año 2000. Ha previsiones de que los cultivos de la caña de azúcar seguirán creciendo por las próximas décadas, lo que genera controversias acerca de los impactos sociales y ambientales asociados, los cuales son apenas parcialmente evaluados en el planeamiento de energía. Este artículo tiene como objetivo presentar una guía de Evaluación Ambiental Estratégica para subsidiar el planeamiento de la expansión de la caña de azúcar presentada en el Plano Decenal de la Expansión de Energía Brasileña. Los principales aspectos positivos de esta guía son: integración de los temas ambientales, sociales y económicos ofreciendo orientación estratégica y de sostenibilidad para la toma de decisiones; propuesta de indicadores de sostenibilidad con disponibilidad de datos en las cuencas; y las directrices para la evaluación de escenarios alternativos a los establecidos en el planeamiento de energía. Se considera que este guía permite la integración de la sostenibilidad en la expansión de la caña de azúcar con el apoyo de la Evaluación Ambiental Estratégica.

Performance criteria	Comments on the proposed SEA roadmap
Integrated	The roadmap covers sustainability issues related to the sugarcane expansion for defining and for performing a comprehensive analysis of the critical decision factors that were discussed in thematic workshops with experts for integrating themes.
Sustainability-led	The roadmap provides the consideration of various development alternatives related to the projections of scenarios of the sugarcane sector expansion and monitoring by using sustainability indicators.
Focused	The roadmap enables the definition of strategic objectives which are directed to the main relevant issues regarding the sustainable expansion of sugarcane, which in turn can be integrated into the analysis of the proposed sustainability indicators.
Accountable	The roadmap as proposed can be carried out in a transparent and participatory manner, allowing detailed consultation by the public about the decisions taken and their justifications.
Participative	The roadmap is proposed to accommodate broad public participation in several stages, as well as that of the specialized technical and scientific community.
Iterative	The roadmap is presented to only one of the planning cycles, wherein in the next cycles review and suggestions for modifications and adjustments may occur, based on continuous improvement.

CDF	Description
Land use change and food security	Corresponds to understanding the current land use change process, aiming to capture the relationship between the sugarcane plantations expansion, with the remaining areas of agricultural, pastoral and ecological protection. The objective is to identify whether and how the trends of planned sugarcane expansion are occurring. The food security issue is also a theme present in this context.
Land ownership and control instruments	Considers the assessment of issues related to land ownership and the legal relationship of the sugarcane-producing areas . The relevant aspects are inserted to demonstrate the suitability of areas for sugarcane expansion, by specific devices such as the Agro-Environmental and Agro-Ecological Zoning and other planning instruments related to River Basins Plans, Management Plans and Master Plans that interfere with the sugarcane expansion.
Ecosystem services	As regards natural resources, from the perspective of ecosystem services, which should be used based on the assumptions of sustainable development. For natural resources affected by the SEA object, surface and underground water resources, biodiversity and soil resources are considered. Waste and inputs compose this balance in order to reduce the consumption of natural resources.
Local community well-being	Aims to understand how the sugarcane expansion may affect the socioeconomic and environmental dynamics of the area under review. Considers the implications of generating employment, remuneration and income distribution, in addition to issues related to the working conditions of employees in the sugarcane industry, particularly of the crop, cases of slave labor, among others. Infrastructure and access to sanitation, as well as working conditions issues are also considered.
Air quality and greenhouse gases	Considers aspects relative to air quality and respiratory health, especially related to the implications of sugarcane burning in practice. Issues such as energy efficiency by cogeneration and reducing greenhouse gas emissions underlie the aspects highlighted here.

CDF	Scenarios
Land use change and food security	Business-as-usual scenario: food production levels are significantly reduced in the watershed, with the replacement of mainly maize crops, are the most affected by this replacement.
Land use change and food security	Sustainability scenario: areas of underutilized pasture would be sufficient to meet the land demand for cropping sugarcane in a moderate sugarcane expansion. Eventual replacement of crops would have no significant impact on food production levels in the watershed.
Land ownership and control instruments	Business-as-usual scenario: the expansion of sugarcane would be directed to areas defined by the integrated analysis of the current land use map and the Agro-Ecological Zoning sugarcane map .
Land ownership and control instruments	Sustainability scenario: for identifying suitable areas for accommodating sugarcane expansion, an integrated analysis of current land use, the Agro-ecological sugarcane zoning, Watershed plans, Management Plans and Municipal Master Plans and the contents of applicable control instruments is undertaken.
Ecossystem Services	Business-as-usual scenario: replacing food production areas can reduce the supply of cultural and regulation ecosystem services and cultural adjustment.
Ecossystem Services	Sustainability scenario: sugarcane crops preferably replace underutilized pasture areas while still respecting ecological corridors helping to increase ecosystem services supply.
Welfare of the local community	Business-as-usual scenario: sugarcane expansion will not necessarily be coupled to socioeconomic improvements in the municipalities and workers affected.
Welfare of the local community	Sustainability scenario: sugarcane expansion should reflect an improvement in the employees' working conditions and also in the socioeconomic conditions of the municipalities affected.
Air quality and greenhouse gases	Business-as-usual scenario: the increase in the areas of sugarcane expansion for supplying biofuels targets contributes to the partial substitution of fossil fuels and consequently reduces the emission of greenhouse gases and improves air quality in general.
Air quality and greenhouse gases	Sustainability scenario: a moderate expansion in sugarcane crops tends to encourage the development of alternative sources of energy and consequently to reduce the emission of greenhouse gases within the limits imposed by the other CFDs. Good practice in sugarcane handling and harvest should be used for keeping good health and safety conditions at work and air quality.
