Background: Brazil, one of the largest greenhouse gas emitting countries in the world, emitted approximately 2 billion gigatonnes of carbon dioxide (CO2) in 2018. This data is practically the same recorded in the previous year, suggesting that the country’s trajectory of CO2 emissions is stabilized. Methods: This study presents an overview of environmental protection and climate change mitigation policies adopted in Brazil, as well as makes use the multilevel regression modeling technique to investigate the relationship between economic activities variables in relation to CO2 emissions over the years of 1970 to 2018 in all Brazilian states. Results: The results show that the CO2 emissions in the states have the same behavior as the timeline of the change in land use. Conclusions: The public policies and actions by society and the private sector were fundamental to the reduction verified from the year of 2004 that followed until 2010, both in CO2 emissions and in the change in land use and forests. As of this year, there has been a trend towards stability in CO2 emissions. Another important characteristic is that even with a drop in the number of deforestation, the production variables continued to grow, which shows that there may be an increase in production activities, while there is a reduction in deforestation and in CO2 emissions.

Climate change is a global environmental threat to all economic activities, especially the livestock activity. The South of Tunisia, where animal husbandry is a fundamental element of the domestic economy, is more influenced by these negatives effects due to the arid climate. The objective of this study is to identify strategies and levers mitigation and adaptation to climate change developed by breeders on based on available factors. For this purpose, a survey conducted among 73 breeders on the rangelands of El Ouara, in the South of Tunisia. Results emerges that breeders use various adaptation strategies principally, supplementation, integration agriculture-livestock and conduct’s mode through different types such as association. The result of the model reveal that age of breeder, herd size, agricultural area, member of an association, subsidies and well ownerships are the most factors which significantly influence the adaptation choices of breeders to cope to climate change. The results proved too that adaptation to climate change was inhibited by many factors such as luck of workforce labor, lack of water and financial resources as well the degradation of the rangelands.

Mitigation And Adaptation

A crescente concentração atmosférica de alguns Gases de Efeito Estufa (GEE) é comprovadamente a principal responsável pelo aquecimento global. Isto tem levado vários países a se preocuparem com as consequências desse fenômeno. O aquecimento da atmosfera está ocorrendo de forma não natural e por interferência humana, o que pode levar a mudanças no clima. Nas últimas décadas, tem sido observado aumento na frequência e intensidade de secas, inundações, ciclones, derretimento de geleiras, aumento do nível do mar, etc. Esta nova realidade climática pode afetar negativamente a agricultura e outras atividades econômicas. Muitas propostas têm sido apresentadas para atenuar os efeitos deste problema. No caso da agricultura, tecnologias sustentáveis podem ser adotadas para mitigar emissões de GEE, e ao mesmo tempo promoverem a retenção de carbono na biomassa e no solo. Durante a COP-15, em Copenhague, Dinamarca, o governo brasileiro assumiu um compromisso voluntário de redução das emissões de GEE projetadas para 2020, entre 36,1% e 38,9%, estimando assim uma redução da ordem de 1 bilhão de Mg de CO2 eq. Palavras - chave: Agricultura sustentável, política pública, agricultura de baixa emissão de carbono.  Sectoral Plan for Mitigation and Adaptation to Climate Change for a Consolidation Economy Low Carbon Agriculture - ABC PLAN  ABSTRACTThe greenhouse gases (GHG) concentration in the atmosphere are increasing and this process is the principal  cause of the Global Warming. The consequence of this phenomenon has worried many countries. The atmospheric warming is occurring by non-naturally means due to human interference and it can lead to climate change. In the last decades, it has been observed increasing intensity of dry seasons, floods, cyclones, tornadoes, melting glaciers, increase in sea level, etc. This new climate scenario can adversely affect agriculture and other economic activities. A lot of proposals have been presented to mitigate the effects of Global Warming. In agriculture, sustainable technologies can be adopted to mitigate GHG emissions, while promoting the retention of carbon in biomass and soil. In the last COP-15, in Copenhagen, Denmark, the Brazilian government committed to reducing GHG intensity by 36.1% and 38.9% by the year 2020. It is estimated that about 1 billion Mg CO2 equivalent will be sequestered from the atmosphere.  Keywords: sustainable agriculture, public policy, agriculture in low-carbon.

ABSTRACTLand use and the management of our natural resources such as soils and water offer great opportunities to sequester carbon and mitigate the effects of climate change. Actions on forestry, soil carbon and damaged peatlands each have the potential to reduce Scottish emissions in 2020 by hundreds of thousands of tonnes. Most actions to reduce emissions from land use have beneficial effects on other ecosystem services, so if we can cut emissions we can in many circumstances improve the environment. The cost of reducing emissions through land use change can be low in relation to other means of cutting emissions. The Scottish Land Use Strategy and the Ecosystem Approach it calls for, employing the concept of ecosystem services, offers a way of balancing environmental, social and economic demands on the land. Scotland's land, soils, forests and waters are all likely to be significantly altered by future climate change. Each of these components of the land-based environment offers opportunities for mitigation and adaptation to climate change. The emerging new imperatives for securing food, water and energy at a global level are equally important for Scotland, and interact with the need for environmental security and for dealing with climate change.

The theme of global sustainable development has changed from environmental management to climate governance, and relevant policies on climate governance urgently need to be implemented by the public. The public understanding of climate change has become the prerequisite and basis for implementing various climate change policies. In order to explore the affected factors of climate change perception among Chinese residents, this study was conducted across 31 provinces and regions of China through field household surveys and interviews. Combined with the residents’ perception of climate change with the possible affected factors, the related factors affecting Chinese residents’ perception of climate change were explored. The results show that the perceptive level of climate change of Chinese residents is related to the education level and the household size of residents. Improving public awareness of climate change risk in the context of climate change through multiple channels will also help to improve residents’ awareness of climate change. On the premise of improving the level of national education, improving education on climate change in school education and raising awareness of climate change risk among dependents will help to improve the level of Chinese residents’ awareness of climate change, which could be instrumental in promoting public participation in climate change mitigation and adaptation actions.

Mitigation And Adaptation

In a world where changes in land cover and climate happen faster than ever due to the expansion of human activities, narrowly distributed species are predicted to be the first to go extinct. Studies projecting species extinction in tropical regions consider either habitat loss or climate change as drivers of biodiversity loss but rarely evaluate them together. Here, the contribution of these two factors to the extinction risk of narrowly distributed species (with ranges smaller than 10,000 km2) of seed plants endemic to a fifth-order watershed in Brazil (microendemics) is assessed. We estimated the Regional Climate Change Index (RCCI) of these watersheds (areas with microendemics) and projected three scenarios of land use up to the year 2100 based on the average annual rates of habitat loss in these watersheds from 2000 to 2014. These scenarios correspond to immediate conservation action (scenario 1), long-term conservation action (scenario 2), and no conservation action (scenario 3). In each scenario, areas with microendemics were classified into four classes: (1) areas with low risk, (2) areas threatened by habitat loss, (3) areas threatened by climate change, and (4) areas threatened by climate change and habitat loss. We found 2,354 microendemic species of seed plants in 776 areas that altogether cover 17.5% of Brazil. Almost 70% (1,597) of these species are projected to be under high extinction risk by the end of the century due to habitat loss, climate change, or both, assuming that these areas will not lose habitat in the future due to land use. However, if habitat loss in these areas continues at the prevailing annual rates, the number of threatened species is projected to increase to more than 85% (2,054). The importance of climate change and habitat loss as drivers of species extinction varies across phytogeographic domains, and this variation requires the adoption of retrospective and prospective conservation strategies that are context specific. We suggest that tropical countries, such as Brazil, should integrate biodiversity conservation and climate change policies (both mitigation and adaptation) to achieve win-win social and environmental gains while halting species extinction.

While various measures of mitigation and adaptation to climate change have been taken in recent years, many have gradually reached a consensus that building community resilience is of great significance when responding to climate change, especially urban flooding. There has been a dearth of research on community resilience to urban floods, especially among transient communities, and therefore there is a need to conduct further empirical studies to improve our understanding, and to identify appropriate interventions. Thus, this work combines two existing resilience assessment frameworks to address these issues in three different types of transient community, namely an urban village, commercial housing, and apartments, all located in Wuhan, China. An analytic hierarchy process–back propagation neural network (AHP-BP) model was developed to estimate the community resilience within these three transient communities. The effects of changes in the prioritization of key resilience indicators under different environmental, economic, and social factors was analyzed across the three communities. The results demonstrate that the ranking of the indicators reflects the connection between disaster resilience and the evaluation units of diverse transient communities. These aspects show the differences in the disaster resilience of different types of transient communities. The proposed method can help decision makers in identifying the areas that are lagging behind, and those that need to be prioritized when allocating limited and/or stretched resources.
