El sector sucroenergético, responsable por la producción de caña de azúcar y su transformación en azúcar, alcohol y/o energía eléctrica, ha encontrado desde inicios del siglo XXI una nueva forma de expansión basada en los términos actuales del desarrollo sostenible. El objetivo de este artículo fue analizar en el periodo contemporáneo, de qué modo las políticas públicas nacionales e internacionales, aliadas a las agroindustrias sucroenergéticas y actores locales, se apropiaron del discurso de la sostenibilidad. Así como comprender cómo las medidas derivadas de este nuevo paradigma terminaron por justificar la expansión del sector sucroenergético. La metodología aplicada fue basada en la revisión bibliográfica, colecta de datos agropecuarios, también como en investigaciones de campo. Fue posible evidenciar que la apropiación del discurso sobre desarrollo sostenible se volvió estratégico a fin de mantener y expandir el sector sucroenergético, exponiendo sus acciones a favor del medio ambiente. Aún así, se pudo verificar el reconocimiento por parte de los actores, sobre las contradicciones existentes entre los principios de la conservación del medio ambiente y la realidad de las acciones que derivan del discurso sobre la sustentabilidad. The sugar-energy industry sector, responsible for the production of sugar cane and its transformation in ethanol and/or electric energy, has been known since the beginning of the XXI century a new expanded phase based in the real terms of the sustainable development. The aim of this article was to analyse in the contemporary period in what way the public politics, national and international ones, together with the agri-business sugar-energy industry and local actors borrowed the speech of sustainability. We also intended to understand how the measures from this new paradigm concluded to justify the expansion of the sugar-energy industry sector. The methodology is based on the bibliography research, in the farming data surveys as well as in the analysis of developing programs and finally in the camping research. The work highlight that the assumption of the sustainable development speech became strategy to the maintenance and expansion of the sugar-energy sector, showing its action in favor of the environment. However, it was seen that the actors admit contradictions existing between the principles of conservation of the environment and the reality of the actors from the sustainability speech O setor sucroenergético, responsável pela produção de cana-de-açúcar e sua transformação em açúcar, álcool e/ou energia elétrica, conhece desde o início do século XXI uma nova fase de expansão baseada nos termos atuais do desenvolvimento sustentável. O presente artigo objetiva analisar no período contemporâneo o modo como as políticas públicas nacionais e internacionais, juntamente com o agronegócio sucroenergético e os atores locais, apropriaram-se do discurso da sustentabilidade, bem como compreender como as medidas decorrentes desse novo paradigma findaram em justificar a expansão do setor sucroenergético. A metodologia é baseada na pesquisa bibliográfica, no levantamento de dados agropecuários, assim como na análise de programas de desenvolvimento e, por fim, em pesquisas de campo. O trabalho evidencia que a apropriação do discurso do desenvolvimento sustentável se tornou estratégico para a manutenção e expansão do setor sucroenergético, expoente as suas ações em favor do meio ambiente. Contudo, foi verificado que os atores admitem as contradições existentes entre os princípios da conservação do meio ambiente e a realidade dos atos decorrente do discurso da sustentabilidade.

Esse projeto de três anos (2021–2023) baseia-se no estudo de longo prazo que o CIFOR e seus parceiros produzem sobre REDD+ desde 2009, intitulado “Estudo Comparativo Global (GCS)”. Este estudo produziu informações, análises e ferramentas baseadas na ciência para promover resultados eficazes, eficientes e equitativos (3E) na implementação de REDD+, incluindo direitos e meios de subsistência seguros para os povos indígenas e as comunidades locais.

This research was conducted to analyse the problems, knowledge and needs of farming households’ – who are the beneficiaries of the project – in order to propose interventions that meet their needs. The research data collection was based on three strategies, namely: (i) household questionnaires; (ii) focus group discussions with groups of farmers’ association members (iii) semi-structured interviews targeted at community leaders, farmers’ association leaders and extension agents working in the four villages studied. In total 166 households were administered a questionnaire, four focus groups consisting of 04 to 12 people were organized; and 10 key informants were individually interviewed.

Mozambique is considered one of the countries that will suffer significant negative effects of climate change, in particular droughts, floods and cyclones. The district of Chicualacuala, due to its geographical location, in an area with semi-arid characteristics, will suffer the consequences of cyclical droughts and floods, high temperatures and desertification. The population will be negatively affected by these phenomena, as their survival is dependent on farming and the exploitation of natural resources. On top of these factors, there is weak development of infrastructure and social services in the district. The main effects of climate change include: the reduction of agricultural productivity, loss of crops, decrease in the availability of pasture, reduction in the availability of water, higher incidences of disease and death of livestock, and land degradation. This could, therefore, lead to the reduction of household income, increased food and nutritional insecurity, and the increase in the number of cases of diseases such as malaria, cholera and diarrhea in this population.

In recent years, several works have been accomplished in order to analyze the spectral response of coffee crop fields cultivated in full sun. However, the number of papers related to the monitoring of shaded coffee systems is reduced although this kind of cultivation is very important from the perspective of climate change and agriculture. In addition, the biomass of coffee systems can store carbon, which is a mitigation action. In this context, this paper presents the assessment of the meteorological variation joined with the biomass increase in three different coffee plantation systems: full sun, shaded coffee associated with legumes (SAF), and shaded coffee with Macadamia trees. We used Landsat-5 images from 2004 to 2010, and the NDVI and SAVI indexes. LAI index measured in the test area during all 2009 year. The results showed that the shaded coffee systems presented the NDVI and SAVI indexes with higher values than those found with the system of planting in full sun what corroborates the idea of greater amount of biomass in this type of planting. All indexes present the seasonal rain variation. One month after a large period of drought the indexes NDVI, SAVI and LAI decrease. The NDVI and SAVI indexes presented high correlation with the measured LAI. The shaded coffee system and the full sun coffee reached high vegetation indexes what indicate a high concentration of biomass. This factor should be considered in the decision making process since is important to take advantage of cultivation systems acting as carbon sinks.

A crise climática é pauta central das discussões socioambientais em escala global. Isto porque provocaefeitos já perceptivos, a partir da elevação da temperatura da terra, com consequente aumento deeventos extremos. As cidades sofrem forte impacto, uma vez que são onde se encontra grande parte docontingente populacional mundial. Neste sentido, há de se pensar sobre a sua preparação e adaptaçõesnecessárias no âmbito do planejamento urbano para que seja possível a minimização de danossocioambientais. O presente artigo objetiva analisar de que maneira o tema é tratado no Plano Diretorde Florianópolis vigente, uma vez que o município não possui um plano de adaptação urbana paraenfrentamento à crise climática. A metodologia partiu de revisão bibliográfica com posterior análisecartográfica para avaliar a adequação do Plano Diretor de Florianópolis às mudanças climáticas,identificando lacunas no planejamento urbano e a necessidade de políticas públicas mais robustas eintegradas. Como resultado, verificou-se que o assunto é tratado de maneira superficial, não estabelecea elaboração de planos de adaptação, tampouco cria objetivos e metas para lidar com os efeitos dasalterações do clima. Ainda, observou-se o estabelecimento de regras permissivas de urbanização sobreáreas de risco e de proteção ambiental. The climate crisis is at the forefront of global socio-environmental discussions, considering it is alreadycausing perceptible effects due to rising temperatures, leading to an increase in extreme events. Citiesbear a significant impact as they host a large concentration of the world's population. Therefore, it iscrucial to consider their preparedness and necessary adaptations within urban planning to minimizesocio-environmental damage. This article analyses how this issue is addressed in Florianópolis' MasterPlan, given the municipality's lack of an urban adaptation plan to address the climate crisis. Themethodology consisted of a literature review followed by cartographic analysis to evaluate the adequacyof Florianópolis' Master Plan in addressing climate change, identifying gaps in urban planning andhighlighting the need for more robust and integrated public policies. The findings reveal that the topic issuperficially addressed, with no development of adaptation plans or defined objectives and goals tomitigate the effects of climate change. Additionally, permissive urbanization rules were observedregarding risk areas and environmental protection.

The current biophysical characterization work was carried out in the Chicualacuala district, as part of the IIAM-CCAFS collaborative project “Managing climate Related Risks to Improve Livelihood Resilience and Adaptive capacity in Agricultural Ecosystems in Southern Mozambique”. Its main objective was to identify, describe, classify and map the main land units and uses in the districts, and evaluate their current potential suitability for agriculture and livestock in order to make recommendations to promote the sustainable use of resources.
