Lightning Leaders
AbstractSchonland et al. (Progressive lightning, 6, Proc. Roy. Soc. (London), A168, 455-469, 1938), in their seminal streak camera studies of lightning, have identified four events of a peculiar type of negative stepped leader that they termed β2, a rather rare variant of the type β leader and in it the second and slower stage of the leader is associated with the appearance of one or more fast dart streamers, which travel rapidly down from the cloud along the previously formed track and cease when they have caught up with the slower leader-tip. During two different campaigns between 2007 and 2011 in Tucson, Arizona, USA, and in São José dos Campos, São Paulo, Brazil, we recorded seven downward leaders that fit in the type β2 description given by Schonland et al. (1938). All cases occurred between about 5 and 32 km from a high-speed camera that was operating at 4000 frames per second and three of them could also have their electric field changes measured. All the dart streamers that we observed had speeds between 106 and 107 m s-1, in agreement with previous observations of recoil leaders (RLs). Also, during the development of the three cases whose electric field change data was available it was possible to identify a sequence of microsecond-scale pulses preceding the development of the Considering the similarities in the optical and electric field signatures of both phenomena, we propose that the type β2 negative leaders are the visible manifestation of the development of RLs that were initiated inside the cloud and propagate below the cloud-base during the development of a bipolar, bidirectional leader that precedes a lightning flash to ground. The RLs are initiated in and propagate through channels that were previously ionized by the in-cloud positive portion of a bidirectional leader, eventually connecting to one of its active branches. When they do an intense return pulse of luminosity that optically appears as the dart streamer reported by Schonland et al. (1938) is produced and propagates until it reaches the lower tip of the negative downward portion. After the RL process is completed the downward negative stepped leader portion of the bidirectional leader continues its development normally, with the possibility of occurrence of other RLs, until it reaches the ground and produces a return stroke.

AbstractThe Amazon floodplain ecosystem links large-scale climatic phenomena to the lives of animals (including people), plants, and other organisms that live within it. The floodplain is subject to seasonal changes in water level that can reach up to 16m, as it aggregates rainfall inputs from the entire Amazon basin. The amount and distribution of such rain is related to annual variations in the Tropical Atlantic and Pacific Oceans sea surface temperatures. On the other hand, the assemblies of species that are found within the floodplain depend to a large extent on flooding dynamics. Moreover, floodplains of the major rivers are home to over 70% of the human population living in the Amazon. Within them people fish, raise cattle, grow crops, transport goods, and have leisure. People depend on its biodiversity, though several species have already had their populations drastically depleted due to over-hunting and over-fishing. To contribute to the understanding of how the predicted increases in the frequency of droughts and other extreme climatic events in the Amazon will impact the floodplains present biodiversity, and its biogeochemistry, it is thus necessary to understand the dynamics of the floodplain ecosystem. Here, we begin such investigation from a large-scale perspective. We consider the land cover characteristics of the floodplain (woody vegetation, annual herbaceous vegetation, and open water), and how its spatial and temporal dynamics are related to the flood cycle. We use multi-scale analysis of remote sensing datasets, geographical information systems, hydrograph analyses, fieldwork and several analytical techniques. Preliminary results show that cover types with faster dynamics, such as macrophyte assemblies, respond quickly to extreme droughts. Impacts on these habitats might be carried over to other components of the system, thus influencing carbon fixation and transformation, animal migration patterns, and fish abundance and availability.

AbstractIn Brazil, the Human Right to Adequate Food was institutionalized on January 2010, when adequate feed was incorporated within the Citizens Social Rights as part of the Brazilian Federal Constitution. Despite that, the access to adequate food necessary to guarantee and promote such rights has been limited by consequences of Social-economic and Environmental Global Changes (ERICKSSEN, 2008; EAKIN, 2010). Cities' expansion in size and number, and population growth concentrated in urban areas can reduce viable spaces near cities to produce fresh food to respond to the rising demand for food by urban consumers (FAO-FCIT & RUAF, 2009). Vegetables are vital food for a healthy human diet (Tofanelli, 2007), and their long route within the market chain represents a set-back step between production and consumption, resulting in great losses due to high perishability of these products (35% of total Brazilian production is lost before consumption), raising prices (Tofanelli, 2007) and influencing negatively on the access to food. In this context, the identification of areas close to consumption centers and suitable for vegetables production, can subsidize the formulation of public policies, and be part of a core adaptation mechanism to achieve food security of urban population in a near future. Thus, this work aimed to apply GIS techniques to build a map of potential areas suitable to crop horticulture in the micro region of São José dos Campos, São Paulo, Brazil. We adopted biophysical, infrastructure and spatial zoning data (e.g. soil types, slope, river and road networks, conservation reserves and urban areas) and spatial analysis techniques available in SPRING 4.3.3 software. The results provide a rich material to support stakeholders´ discussion about potential areas where horticulture could be developed and/or should be tackled as priority areas in a near future to improve the nutritional security of the citizens of this region.

semi-arid region
AbstractThe Brazilian northeast is a region characterized by a semi-arid climate, with precipitation highly variable spatially and in time, with high atmospheric evaporation demand. Model simulation, associating future climate change to anthropogenic use of the soil, suggest an even drier climate in the region in the future, with serious effects in the hydrological and nutrient balances. The intensification of dry climate and extreme events (drought spells or intense precipitation) has the potential to impact significantly the predicted 75millions people leaving in the region by the middle of the century. As example, some recent studies indicate that, considering the A2 IPCC scenario, the region might loose 50% in its agricultural potential by 2050. The aim of this work is to present a suit of studies that are being conduct in the Brazilian Northeast looking at land use mapping to support modeling (IBIS, CENTURY) and field experimental activities on nutrient cycling, agricultural production, emissions of green house gases, climate change scenarios and food security. Vulnerability and adaptation are being accessed envisioning providing subside for public policies in the region for agriculture production, water use and land use change planning.

Socio-Climatic Vulnerability Index (SCVI)
AbstractBrazil suffers yearly with extreme weather and climate events (such as urban floods) which can be exacerbated in a warmer climate. Although several studies analyzed the projections of climate change in this part of the world, little attention has been done in defining the locations that can be most affected, and consequently making the population more vulnerable, in a spatially-explicit form. In this study, a spatial analysis of possible climate impacts and a joint investigation merging these climate impacts with social indicators of vulnerability in the Brazilian territory is performed. The Regional Climate Change Index (RCCI) - an index that is able to synthesize the large number of climate model projections available today - is used for the climate analysis, and the "Socio-Climatic Vulnerability Index" (SCVI) is proposed to aggregate local population vulnerabilities to the climate change information. Results from RCCI show two major climatic hot-spots emerging in Brazil: one covering a large area comprising nearly entire Northeast and Centre-West regions, and the other one concentrated in western/southern São Paulo state and the Southern region. The SCVI analysis reveals one major socio-climatic hot-spot over Northeast and a few punctual hot-spots occurring over some of the major Brazilian metropolitan regions. The major contributions of this study are (i) a detailed analysis of the RCCI over Brazil and (ii) the development of an index that can combine a large number of climate model information with social vulnerability indicators. Both indices can be important tools for climate and social scientists dialogue, and to communicate climate change to policymakers in a synthetic and socially-relevant form.

AbstractIn the last decades, 18% of forest cover was cleared by human colonization in the Brazilian Amazon, where the spatial variability of deforestation depends not only on drivers but also on the spatial scale. Spatial variability can be explained by a combination of accessibility measures, public policies, socioeconomic and biophysical aspects that can lead the land use systems to distinct pathways, depending on the existing human-environmental interactions. The understanding of these interactions is a challenge to interdisciplinary research between social and natural sciences, while scientific results can help developing land use policies at different levels. In this context, the main objective of this study is to identify and analyze the role of human-environmental interactions at local and regional scales regarding the land use and land cover dynamics in the Brazilian Amazon. The adopted method consists of an innovative approach that integrates Fuzzy Cognitive Maps (FCMs), built based on spatial data and expert knowledge (Soler et al, 2010), to a framework that analyzes sustainability of social-ecological systems (Ostrom, 2009). FCMs are built using spatial databases at three different spatial resolutions and extents in areas of heterogeneous biophysical and socioeconomic aspects, colonization history and land tenure regimes. A number of empirical methods are employed using detailed deforestation maps, surveying data, agricultural census and household level data to support the background knowledge to build the FCMs. The results indicate feedback mechanisms between deforestation and land prices or dry season severity act differently within different scales, being stronger at broader scales. However, feedbacks among deforestation, accessibility and credits seem to have a similar influence at different scales, but only poor conclusions can be drawn on how they act over scales. Finally, FCMs linked to spatial data can elucidate interactions such as those within institutional arrangements, needed to identify successful or failuring social-ecological systems.

AbstractIn Brazil, the recent urbanization process has acquired a characteristic of expansion that differs from the model highly concentrated in metropolitan areas, expanding in number and size, the medium-sized cities with the same patterns of urbanization than metropolitan areas (CARVALHO, 2003). And as long food production spaces are being reduced as urbanization rises, there is also an increase on demand for food to urban dwellers, dependents on food market (RUAF, 2009) and vulnerable to supply and prices fluctuations. Knowing that global changes are not equal for all, or occur in the same way throughout the globe (Hulme, 2009), impacting most the more vulnerable ones, it is necessary to better understand the connections between urbanized space, food production, environment and people within urban systems. In this sense, this work aimed to understand the ecological dimension of urban agriculture (UA) in intra and periurban areas of the main district of Juiz de Fora, Minas Gerais State, Brazil. The research found 179 areas of UA occurrence, classified as: Social Projects of Municipal Schools, Institutions (public, religious, welfare and medical units), Commercial Productive Areas and Productive Backyards (in one neighborhood - Monte Castelo). Semi-structured interviews and field observations were carried out in a total of 77 areas. Empirically, it was possible to investigate the interactions between actors and environment. The results show a number of 173 cultivated plant species in the areas of UA, many of them, native from Brazil or Latin America, and also 69 species of wild animals that benefit from cultivated areas. The survey also demonstrates the importance of those areas of UA to those involved, for the conservation of natural resources and biodiversity, for the maintenance of traditional knowledge and that it could be considered as a valuable environmental service provision tool for cities' sustainability.

AbstractThere are a wide range of challenges arising from global changes such as increasing globalization and future technological, economic and behavioral changes. Rapid changes, uncertainty and growing risks, are resulting in a great number of limitations to agricultural policy and practice that reveal the inadequacies for their long-term sustainability. Thus, the challenges that impact on agri-food systems require new solutions, such as adoption of new energy sources, new forms of information, communication and technology, new pharmaceuticals and medical knowledge, and also a shift in consumer behavior. The application of these new solutions, may result on the emergence of agri-food systems with new features, very different from what we know today (FRESH, 2009), such as the return of urban and peri-urban agriculture and its multifunctionality in political discourses, social movements and in real lives of cities dwellers all around the world. Noting that, new forms of inquiry are necessary, but for that, it is necessary to have a new perspective on the drivers of changes, and a careful look on the culture or cultural dimension in which the agri-food systems and its actors are inserted. Thus, this essay intends to highlight some topics that are relevant to the discussion on how consumption, stimulated by the market, and the consumers, through their choices, can influence the agri-food systems and be a major factor on political decision choices that could affect the future of human food security.

AbstractFires in Amazonia are a major source of greenhouse gases to the atmosphere, changing carbon and nutrient cycles and severely affecting vegetation characteristics. Descriptions and summary of how fires occur have thus broad interest for environmental studies. For example, mathematical relations that can represent fire activity and effects are strongly needed in surface models for climate studies in the region. As indicated by previous studies, contemporary patterns of fire activity in the region can be largely explained by a combination of climate and land-use dynamics. Here we present analyses that explore spatial relationships between fire activity and connection to markets, a major land-use driver in Amazonia. Data on fire activity are based on remote-sensing detections from MODIS sensor between 2001 and 2010. Information on connection to markets for the year of 2006 was calculated considering Euclidean distances and topological connections to important consumption markets, weighted by paved and non-paved roads network. Confronting both datasets, we found that the number of fire detections was different according to the proximity to consumption markets. In summary, low fire activity was related to either very low or very high connectivity to markets. High fire frequencies, on the other hand, were related to intermediate values of connectivity to markets. These broad-scale patterns are consistent with the observed dynamics of deforestation frontiers. Land-cover change in areas with low connectivity to markets is generally difuse. Very high connectivity can be associated with places where fires do not figure as a tool in most cases, such as large-scale agriculture and urbanized areas. These results have thus important implications for environmental studies in the region, by contributing to current descriptions of the relations between fire and land-use change in areas that can provide important ecossystem services.
