As políticas públicas ambientais e a dinâmica do espaço rural no município de Araras (SP)

Historically the evolution of the occupation of ararense territory was due to the expansion of agricultural activities. Such activities were intensified with the transformations engendered by the Green Revolution, increasing the exploitation, the area occupied by agriculture and the deforestation and consequent environmental degradation. Therefore the current reality of rural areas in Araras/SP has shown that part of agricultural practices made it does not guarantee the effectiveness of environmental legislation and the sustainability of farms. Considering the recently implemented environmental policies, such as Law nº 12.651 / 2012, better known as New Forest Code and Decree nº 8.235 / 2014 establishing a period of one year to rural property registered with the Rural Environmental Registry (CAR), as tools targeting to reduce environmental degradation and contribute to building a sustainable rural development. This work aims to analyze the dynamics of the rural municipality of Araras on the environmental situation in some rural properties and actions to be taken by the owners to the full compliance of its properties before the environmental public policy

Inovação tecnológica de boas práticas agrícolas e a informática na gestão agropecuária

This study aims to develop innovative proposals for production agriculture management and plans to build a participatory model, through the digital inclusion of members of the family farm gathered in a cooperative venture seeking to establish new environmental management efficiency for household production. The first part of the hypothesis assumes that a major obstacle to the insertion of small family farms into the markets is skilled labor, human capital. A training model has been developed for traceability and tracking activities on family farms, based on the atemoya culture. The second hypothesis predicts that it is possible to create a model that is scientifically supported by widely accepted rules derived from GlobalGAP standard certification, a global benchmark for good agricultural practices. Using these rules the model seeks to achieve the traceability of agricultural products and operations from the preservation of identity information within the production chain. The results obtained by the computerized system confirmed the presented hypotheses by demonstrating that technological innovation through intensive communication and information technologies education as well as other associated forms are important drivers of regional development, especially if implemented through a digital inclusion project using the state program Infocentros Access São Paulo.

Análise das eficiências energética e econômica de dois diferentes sistemas de produção de leite bovino em explorações familiares

This study aimed to analyze the energy efficiency ratings and cost of farming families producing milk in the city of Pardinho (SP). The hypothesis that guides the study is that energy expenditure may be coincident with the economic expenditure showing that there is a relationship between these flows, which can be sustainable or not. To better define the producers studied criteria were used in the official system of rural credit FEAP. Through primary data obtained by the speeches, the itineraries were reconstituted technical detailing the operations employed. Thus, we found two producers with different technical routes. The producer was the one who got one of the highest efficiencies 8.66 and 1.48 respectively. Related to the efficiency, we can see that are close related and when there is a broader idea of the allocation of energy resources and, thus, a better view of the sustainability of the agro ecosystem.

Eficiência energética e econômica da produção de leite bovino em explorações familiares no município de Pardinho, região de Botucatu- SP

The study aimed to analyze the energy and economic efficiency rate family farms producing milk in the county of Pardinho, Sao Paulo State. The criteria used to define producers in this study is that outlined by the Brazilian agricultural credit system FEAP (Fund Expansion of Agribusiness Paulista). Through primary data, obtained by verbal reports, the agroecosystem technical itineraries were re-established, detailing the process applied, machinery, implements, equipment, supplies and manual work. These were transformed into energy and economic units, which allowed determining the established connection between energy economics outputs and inputs. The hypothesis of this study is that the energetic expenditure may be coincidental with economic expenditures. The energetic and economic flows were analyzed, using a structure of expenditures, by type, source and form of gross energy, as well as the energetic point of view. Four producers were found to have different technical itineraries. Producers 1 and 2 achieved the highest energy and economic efficiency rates. The producer with the lowest efficiency rates was producer 4. The energy sources not renewable like chemical fertilizers were the most used reaching an average of 82.9% for the energy and 52.86% for the economic expenditures. When comparing energy and economic efficiency it is possible to verify that both forms of analysis are close, obtaining a broader idea about energy resources allocation.

Estrutura Institucional da Sustentabilidade: Panorama Comparativo Preliminar Brasil - França.

A sustentabilidade vem sendo perseguida em todos os segmentos da economia tanto dos países desenvolvidos quanto em desenvolvimento. Especificamente no que diz respeito ao setor rural destes países não poderia ser diferente. O presente trabalho se propõe a analisar e comparar o Brasil e a França em termos das principais semelhanças e diferenças nas suas estruturas institucionais voltadas para a promoção do desenvolvimento rural sustentável. Para tanto, foram utilizados os métodos Dedutivo e Indutivo. Verificou-se que as estruturas institucionais de ambos os países são relativamente semelhantes, muito embora haja especificidades relacionadas às distintas realidades rurais destes países em termos de atividades agropecuárias, florestais, propriedades rurais, dentre outros aspectos. O desenvolvimento rural sustentável desempenha, assim, um papel importante nas políticas nacionais, da França e do Brasil, sendo que a agropecuária, o meio ambiente, as energias, o turismo, a educação e a pesquisa são as principais áreas de sustentabilidade em ambos os países. Pode-se observar que, em geral, um Ministério francês responsabiliza-se, em se tratando de temas vinculados ao desenvolvimento rural sustentável, por uma área de ação mais ampla e menos precisa comparativamente a um Ministério brasileiro. Por fim, alguns temas associados ao tema do desenvolvimento rural sustentável são exclusivamente observados nos Ministérios brasileiros, tais como proteção das florestais tropicais, povos indígenas e biocombustíveis.

Acompanhamento da dinâmica do uso do solo em uma bacia hidrográfica no Município de Botucatu (SP) por meio de geotecnologia

The increasing expansion of agricultural activities, without considering the potential and limitations of soils is a potential source of environmental degradation. Thus, the present study assessed the variation of use and occupation in 49 years, between 1962 and 2011 scenarios of watershed of São Caetano - Botucatu (SP). geoprocessing techniques were used in this study. In a Geographic Information System (GIS) - IDRISI – it was integrated information from IBGE digital cards, scale 1:50,000, plus aerial photographs (1962) and satellite images LANDSAT - 5 (2011). In the study area, we can view the progress of the urban area, which in 1962 was not present in the watershed. In 2011, the urban area occupied 21.37% of the total area. Even with this breakthrough occurring in the period of 49 years, there was an increase in the area of natural vegetation, which once occupied only 12.33% of the area (1962), and in 2011 represents 25% of the total area of the watershed, showing an increase in awareness on the importance of preserving nature. Thus, we can conclude that the analysis tools based on GIS enabled us to analyze variations in space and time and to propose alternatives to the correct use and occupation of land.

Diagnóstico de potenciliade das unidades ambientais na bacia do Rio Capivara, Botucatu - SP

This work has the objective to elaborate the potentialities of the farming expand diagnosis of the Capivara River Hydrographic basin, in the Botucatu – SP municipal district, to obtain an interpretation of the system actual situation through the historical trajectory and possible evolution with the assistance of the SIG Ilwis 3.4 and orbital images CBERS 2B, in the pancromatics bands, obtained in 12/07/2008. The potentialities of the farming expand diagnosis was obtained through the physical mean modeling, of the farming expand presents in the studied environment and shows possible line actions to minimize the impacts e reach a sustainable development to the region. The Capivara river basin presents more than 70% of your areas occupied by the anthropic expanding, with the extensive farming predominance, forestall planting, orange and sugar cane. In the potentiality diagnostic analyses notes the good quality of the basin to the farming expand, except the region comprehended by the Botucatu Cuesta and the meadows area. The basin until has a good environmental quality and this diagnosis must serve for a start point to the realization of the territorial ordination as quick as possible to the environment conditions finds remains the same, granting the recovery capability.

Genome wide scan for quantitative trait loci affecting tick resistance in cattle (Bos taurus × Bos indicus)

Abstract Background In tropical countries, losses caused by bovine tick Rhipicephalus (Boophilus) microplus infestation have a tremendous economic impact on cattle production systems. Genetic variation between Bos taurus and Bos indicus to tick resistance and molecular biology tools might allow for the identification of molecular markers linked to resistance traits that could be used as an auxiliary tool in selection programs. The objective of this work was to identify QTL associated with tick resistance/susceptibility in a bovine F2 population derived from the Gyr (Bos indicus) × Holstein (Bos taurus) cross. Results Through a whole genome scan with microsatellite markers, we were able to map six genomic regions associated with bovine tick resistance. For most QTL, we have found that depending on the tick evaluation season (dry and rainy) different sets of genes could be involved in the resistance mechanism. We identified dry season specific QTL on BTA 2 and 10, rainy season specific QTL on BTA 5, 11 and 27. We also found a highly significant genome wide QTL for both dry and rainy seasons in the central region of BTA 23. Conclusions The experimental F2 population derived from Gyr × Holstein cross successfully allowed the identification of six highly significant QTL associated with tick resistance in cattle. QTL located on BTA 23 might be related with the bovine histocompatibility complex. Further investigation of these QTL will help to isolate candidate genes involved with tick resistance in cattle.

Agroindústria familiar : Um mecanismo de estímulo à especialização das atividades na propriedade rural?

Family agroindustry has been considered by several authors as an important reproduction alternative for family-based agriculture. However, this production process, which includes primary (production of raw-materials) and secondary (industrialization of production) activities, is generating a general concern. Can agroindustry, by promoting non-agricultural income for farmers, cause a reduction or, in extreme cases, an extinction of agricultural production in farm estates developing industrialization activities for selling in markets (family agroindustries)? In this sense, the purpose of this research was to analyse whether agroindustry can promote specialisation in family-based farm estates, or whether it is a form of economic diversification, being merely an activity similar to those developed in farm estates before the emergence of this process. The empirical study was conducted in 45 family agroindustries of sugarcane derivatives located in the Northeast of Rio Grande do Sul (Brazil).

Nitrato na dieta de ruminantes como estratégia nutricional para mitigação de metano entérico

A produção de metano entérico está entre as principais fontes de emissão de gases de efeito estufa dentre as atividades agropecuárias, além de gerar perda energética ao animal de até 12% da energia bruta consumida. Assim, o objetivo deste trabalho foi avaliar o uso de nitrato de cálcio encapsulado na alimentação de ruminantes como estratégia nutricional a mitigação de metano entérico. O experimento consistiu de duas fases. Fase I: Foram testadas dietas suplementadas com produto comercial de nitrato de cálcio encapsulado utilizando a técnica semiautomática de produção de gases in vitro. Meio grama de substrato com 50 mL de meio de incubação e 25 mL de inóculo ruminal foram incubados em frascos de vidro (160 mL) à 39 ºC por 24 horas para determinação da melhor dieta a ser testada in vivo. O primeiro ensaio testou a associação entre a monensina (dietas com e sem adição de monensina) e doses de nitrato encapsulado (0; 1,5 e 3% da matéria seca (MS)) para mitigação de metano in vitro. Não foi observada interação entre monensina e nitrato para as variáveis testadas. O segundo ensaio in vitro testou a interação do tipo de dieta com duas relações concentrado:volumoso, 20:80 e 80:20, e a inclusão de doses de nitrato encapsulado (0; 1,5; 3 e 4,5% MS). Embora não foi observado efeito associativo entre dieta e nitrato para redução de metano, foi observada mudança nos produtos da fermentação ruminal, com redução de propionato, em decorrência da concorrência de nitrato e propianogênicas por hidrogênio mais escasso em dietas com menor fermentação. Fase II: Conforme os resultados obtidos na Fase I, na segunda fase foi avaliado o efeito associativo da relação de concentrado:volumoso da dieta e a dose de nitrato sobre a emissão de metano, constituintes ruminais e toxicidade do nitrato in vivo. Utilizou-se seis borregos canulados no rúmen, distribuídos em delineamento experimental quadrado latino 6 x 6, em fatorial 2 x 3. Os fatores foram tipo de dieta (relação concentrado:volumoso 20:80 e 80:20) e inclusão de doses de nitrato encapsulado na dieta (0; 1,5 e 3% MS) em substituição gradual ao farelo de soja, totalizando seis tratamentos. Os teores de substituição do farelo de soja pelo nitrato foram em equivalente proteico de maneira a deixar as dietas isonitrogenadas. Os animais foram adaptados gradualmente a oferta de nitrato dietético para evitar problemas com toxidez. A análise de toxicidade foi avaliada pela taxa de metahemoglobina no sangue dos ovinos 3 horas após a alimentação. Nitrato reduziu a produção de metano em ambas as dietas. Os níveis de metahemoglobina no sangue dos animais não foram alterados pela adição de nitrato. Foi observado efeito associativo entre o tipo de dieta e nitrato para os produtos da fermentação ruminal, como acetato, que aumentou linearmente nas dietas com 80% de concentrado quando nitrato foi adicionado. Concluí-se que nitrato, utilizado de forma segura, é uma promissora estratégia para redução de metano entérico independentemente do tipo de dieta com que está sendo suplementado

Conservadores ou progressistas: como o judiciário de Piracicaba/SP se posiciona nos pleitos pela proibição da queima da palha de cana-de-açúcar

Este estudo analisa os fatores, as tendências e as fundamentações jurídico-ideológicas que permeiam as decisões judiciais em Ações Civis Públicas, impetradas pelo Ministério Público do Estado de São Paulo (MPSP) e Federal (MPF), requerendo a proibição imediata da queima da palha de cana-de-açúcar, na região de Piracicaba/SP. Para isso, foram levantadas, junto aos órgãos jurisdicionais da cidade de Piracicaba, as Ações Civis Públicas impetradas em face de grandes usinas e agropecuárias dedicadas ao cultivo e industrialização da cana-de-açúcar, requerendo a proibição da queima da palha na lavoura desde o advento da Lei nº 7.347 de 1985 até 2014, ano em que finalizou-se a pesquisa empírica desta dissertação. Nesses padrões, a pesquisa arrojou a existência de quatro processos, dos quais foram extraídas para análise a totalidade de vinte-e-um (21) manifestações judiciais. O marco teórico-metodológico empregado foi a abordagem marxista da filosofia da linguagem, perspectiva capaz de proporcionar uma fecunda imersão não só no que se diz, mas nas condições de produção desse dizer, valorizando a função socioideológica da palavra, permitindo vislumbrar a visão social de mundo de quem a emprega ou do grupo social ao qual o autor pode ou não pertencer (VOLOCHINOV,1929; GOLDMANN, 1979). Conclui-se que, nos pleitos judiciais pela proibição imediata da queima da cana-de-açúcar em Piracicaba/SP, o Poder Judiciário se mostra majoritariamente conservador, arguindo e decidindo pela continuidade da prática em evidente defesa do setor sucroalcooleiro. No entanto, se reconhece a importância do tímido mas importante viés progressista por parte do judiciário, uma vez que somente nas contradições presentes nas diferentes práxis jurídicas pode avançar-se no processo permanente de construção de um direito comprometido com a obtenção de igualdade e justiça social.
