In this region there is a fragment occupied by the Conservation Unit (UC) called the National Forest (Flona) of Restinga de Cabedelo. The main objective of the present study is to investigate the role of vegetation in mitigating the urban heat islands of the study area. At first, an analysis of the city's general climatology was carried out using a 30-year historical series of data on temperature, relative air humidity, wind velocity and precipitation using data from an INMET station located in João Pessoa. Posteriorly, air temperature and relative humidity were measured during the months of January to March (dry period) using a Hobo® thermohygrometer U10-003 at 5 experimental points in the study area. These points were distributed in the urban area-FLONA, with three points located in the urban network and two located in the forest with three monitoring points in the urban area and two within the forest itself. For the calculation of the urban heat island, a reference point P05, located in Flona, was used, from which the values were calculated, and afterwards its magnitude was classified. And Thom's thermal index of discomfort was also calculated. The results allowed to characterize the microclimate of the study area and to identify that the environmental changes provoked by the urbanization process directly affect the temperature and relative humidity of the air, as well as in the formation and intensity of heat island. The points located in the urban area P01, P02 presented the highest temperatures, heat islands and IDT, and P03 (closest to the forest) had lower values. On the other hand, P04 and P05 presented the best conditions of temperature, relative humidity and thermal comfort. In this way, a thermal gradient was obtained, where as the monitored points approached the forest, the temperature, islands of heat and thermal discomfort decrease and the relative humidity of the air increases.

Uma análise dos cultivos de macroalgas marinhas no estado do Rio Grande do Norte Autor(es): Barbosa, Êmille Natane de Araújo Orientador: Miranda, George Emmanuel Cavalcanti de Abstract: The seaweed cultivation has been encouraged as an alternative to harvesting in natural beds as well as being a possibility of generating income, reducing the exodus, unemployment, family breakdown and valuation of women's role in generating income and participation of community organization. The aim of this study was to evaluate the sustainability of seaweed aquaculture of Rio Grande do Norte. The analysis considered socioeconomic, technological, and environmental aspects. The research was characterized as a case study, which qualitative and quantitative parameters were evaluated. Data were collected through semi-structured interviews, directed to the seaweed farmers, the presidents of the mariculture associations and aquaculture specialists. The collected data were used to characterize the associations, to identify the socioeconomic profile of the farmers, and to calculate the IDES, ICS, IT, IA and IS indexes. To improve the cultivation technique of Crassiphycus birdiae, an experiment was carried out using the nutrient pulse method. Thirteen treatments were tested, one control and 12 resulting from combinations of four concentrations (0.75 ml/L; 1.5 ml/L; 3.0 ml/L; 6.0 ml/L) of an agricultural fertilizer (VitanTM) and three exposure periods (12h; 24h; 48h). After the period of exposure to the nutrient pulse, the propagules were grown in sterilized seawater for four weeks. The effect of nutrient pulse on growth rate was analysed. The obtained results in the sustainability analysis of the mariculture activity were: High-level Index of Economic and Social Development (IDES – 0.931); Medium level Index of Social Capital (ICS – 0.759); High-level Index of Technology (IT – 0.836); Medium level Index of Environment (IA – 0.633) and medium level Index of Sustainability (IS – 0.790). In assessing the nutrient pulse effect, a progressive increase in the values of fresh biomass and growth rate was observed in all treatments, except for T13, treatment with higher concentration and higher period of exposure fertilizer. The highest increase in fresh biomass and growth rate was found in the T3 treatment (1.5ml/L; 12h), however the statistical analysis did not show any significant difference.

This study of environmental perception is critical to better understand the relationship between humans and the environment and, in the case of this research, the intense contact between farmer and nature. Therefore, this study aimed to characterize the sociodemographic and environmental perceptions of farmers in Dona Antonia Settlements and Gurugi II, Conde - PB, merging information from the subjects of the two locations. Used the Case Study method and to determine the sociodemographic and environmental perception was used mixed questionnaire, field diary, photographic records containing simple observation. For data analysis, there were systematic and qualitative and quantitative approaches. As to the results, 57% of household heads are male, with 41 to 60 years old; family consists of father, mother and son or daughter; has an average income of 2 minimum wages; live basically of agriculture; with predominance of ecological farming practices in his speech and live in settlements with serious environmental problems that influence both in rural villages and rural properties. There is a clear need to understand that farmers involved in this study have attitudes to the environment according to the situations that they are convenient for you to survive in their rural areas. Therefore, the practice does not always correspond to the speech of these farmers, since they are the basic needs and interests that will guide the way that will go to providing better living conditions for themselves and their family.; RESUMO O presente trabalho aborda sobre os estilos de agricultura encontrados nas propriedades rurais pesquisadas nos Assentamentos Dona Antônia e Gurugi II, no Conde – PB. No caso desse estudo, o que interessou particularmente foi identificar os tipos de agricultura de acordo com as práticas agrícolas dos agricultores familiares pesquisados, levando-se em conta alguns aspectos sociais e ambientais que são relevantes para o emprego dos sistemas de produção. Na metodologia foram empregadas as respostas das práticas agrícolas presentes no questionário misto. Realizaram-se observações diretas por meio das visitas de campo e foi utilizado o diário de campo. Foram identificados dois tipos de agriculturas: convencional e agroecológica. As propriedades “N”, “P” e “Z” possuem maior predominância de práticas agrícolas convencionais; as “C”, “L”, “D” e “B” foram agrupadas nas propriedades rurais ditas como agroecológicas, por empregarem práticas ecológicas ao longo dos anos. Os agricultores familiares possuem o poder de escolher e de analisar qual é o tipo de sistema de produção que traz maiores benefícios (sociais, econômicos e ambientais) para si e sua família. Além do mais, na teoria sabem distinguir a agricultura agroecológica da convencional. Portanto, considera-se que as identificações e caracterizações dos sujeitos em grupos fortalecem a idéia de que há diversificação de estilos de agricultura dentro de determinadas comunidades rurais.; ABSTRACT This paper reports about the agriculture of styles found on farms searched in Settlements Dona Antonia and Gurugi II, Conde - PB. In the case of this study, which is of particular interest is to identify the types of agriculture according to the agricultural practices of farmers surveyed, taking into account some social and environmental aspects that are relevant to the use of production systems. In the methodology we used the responses of agricultural practices present in the mixed questionnaire. Direct observations were carried out through field visits and used a field diary and camera. Conventional and agroecological: Two types of agriculture were identified. The properties "N", "P" and "Z" have more prevalence of conventional agricultural practices; the "C", "L", "D" and "B" were grouped in rural properties as agroecological said, by employing green practices over the years. The family farmers have the power to choose and analyze what kind of production system that brings greater benefits (social, economic and environmental) for himself and his family. Moreover, the theory can distinguish agroecological agriculture conventional. Therefore, it is considered that the identification and characterization of the subjects in groups empower the idea that there is a diversification of farming styles within certain rural communities.; RESUMO No mercado de produtos agrícolas existem vários canais de comercialização, onde a venda pode ser basicamente de três tipos: direta, indireta e mista. No caso desse trabalho, usou o termo circuito curto para referir-se aquele tipo de comercialização em que há apenas um atravessador entre o agricultor familiar e o consumidor. Baseou-se nesse conceito para identificar, descrever e propor sugestões de alternativas de circuitos curtos para os produtos agroecológicos, orgânicos e convencionais comercializados pelos agricultores familiares dos Assentamentos Dona Antônia e Gurugi II, no Conde – PB. A pesquisa caracterizou-se por ser qualitativa e foi empregada na metodologia a entrevista semi-estruturada, conversa informal e usou-se o diário de campo. Os resultados obtidos foram que os circuitos curtos dos agricultores familiares pesquisados são muito limitados. Apresentaram vendas diretas apenas através das feiras convencionais e agroecológicas e da comercialização na própria propriedade rural (esta última não ocorreu em todas as áreas); já em relação às vendas indiretas, há sempre a presença do intermediário/atravessador comprando os produtos agrícolas diretamente na propriedade. Por isso este trabalho apontou novas alternativas de circuitos curtos para que o agricultor familiar melhore sua renda através da agricultura e de atividades vinculadas a sua propriedade rural.; ABSTRACT In the market for agricultural products there are several marketing channels, where the sale can be basically of three types: direct, indirect and mixed. In the case of this study, used the term short circuit to refer to that type of marketing where there is just a middleman between the family farmer and the consumer. It was based on this concept to identify, describe and propose suggestions of alternative short circuits to the agro-ecological, organic and conventional marketed by farmers of Settlements Dona Antonia and Gurugi II, Count - PB. The research is characterized by being qualitative and methodology was used in the semi- structured interviews, informal conversation and used the field book. The results were that short circuits of the surveyed farmers are very limited. Presented direct sales only through conventional and agroecological fairs and marketing in their own rural property (the latter did not occur in all areas); already in relation to indirect sales, there is always the presence of the intermediate / middleman buying agricultural products directly on the property. So this work shows new alternatives of short circuits to the family farmer improve their income through agriculture and activities linked to his estate.

However, throughout human history, these ecosystems have been the target of several anthropogenic actions, which end up harming all these types of environments. The aim of this work was to analyze the environmental conditions, the sanitary conditions and the socio-environmental conflicts present in the Paraíba River Estuary, from Porto do Capim to the mouth of the Paraíba River. For this, the work was carried out in the following stages: survey of the main environmental problems through on-site visits; water quality analysis at 14 points throughout the study site, in two seasonal periods, rainy and dry season. Analysis of bioaccumulation of trace metals in three locations in the estuary. Survey of the basic sanitation conditions of the communities near the Paraíba River and the prevalence of some waterborne diseases. Environmental perception study with students about the estuary. The results showed several anthropic actions that negatively influence the environmental conditions of the estuary. Among the main ones, there was deforestation, discharge of domestic sewage, solid waste disposed inappropriately, burning, loss of biodiversity, among others. The water analysis showed loss in water quality caused by sources of continuous pollution, not dependent on leaching, that is, domestic sewage and also by leaching processes, mainly by agriculture. It was observed in point 1 (P1), that ammonia concentrations were above the values allowed by CONAMA resolution n ° 357/2005. Regarding bioaccumulation, despite the results confirming the presence of trace metals, all were below the values allowed by current legislation. However, aluminum showed high values, especially for the Anamalocardia Mollusca from Porto do Capim, which is under direct influence of the old Roger dump and part of the old city and Bayeux, however there is no standard with maximum values allowed for this element. Regarding sanitary conditions, the data survey demonstrated the precariousness of basic sanitation, mainly access to treated water, sewage and waste collection. Such facts have a direct influence on the number of waterborne diseases, with Ascaridiasis being the main one. Environmental awareness and awareness studies have shown that students are aware of the problems surrounding the estuary, however, many of them are indifferent to this scenario. Thus, it is necessary to implement public policies to improve basic sanitation. The sewage treatement could be with incentive and training for the construction of ecological pits for black and gray waters. There is also a need for continuous and integrated environmental education.
