Item Análise de impacto ambiental na zona de amortecimento do Parque Nacional das Emas a partir da pressão agropecuária(Universidade Federal de Goiás, 2015-10-16) Barbosa Neto, Manoel Alves; Ribeiro, Dinalva Donizete; http://lattes.cnpq.br/3182325621648634; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Abdala, Klaus de Oliveira; Ferreira, Manuel Eduardo; Carneiro, Gabriel TenagliaThe state of Goiás, with 97% of its area inserted in the Cerrado biome, has only 3% of the territory protected in conservation units, among them the Emas National Park, considered a priority area for biodiversity conservation. Weather conditions, geomorphological and government development with occupation programs since the 70s, turned the park region an important hub national agriculture, which represents major threat to this protected area. This study examined the effectiveness of the buffer zone established by the management plan for protecting this conservation unit to agricultural pressure on its surroundings using the PEIR matrix. Despite the regulations of the buffer zone, the standards set from the same are not being fulfilled as regulated. The results obtained can support public policies that promote behaviors appropriate to the functionality of the Buffer Zone of Emas National Park.Item Efeito da concentração da soja e algodão na produtividade de culturas essencialmente dependentes da polinização animal no centro-oeste brasileiro(Universidade Federal de Goiás, 2021-07-05) Frias, Vinícius Diniz; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Abdala, Klaus de Oliveira; Franceschinelli, Edivani Villaron; Ferreira, Marcelo Dias PaesAccording to FAO’s data (2004) approximately 73% of agricultural species cultivated worldwide are pollinated by bees. However, a steady decline in the population of these pollinators has been observed in several countries and the indiscriminate use of pesticides has been pointed out as a major factor in this process. This master teses aimed to analyze the effect of the locational presence of soybean and cotton crops which use pesticides that are harmful to pollinators on the productivity of crops sensitive to pollination in central-western Brazil (a region that has significant productivity for agribusiness in Brazil). For this, a quantitative approach was adopted using statistical tools especially regression analysis through the development of an empirical model in order to test the hypothesis that municipalities that have not planted soybeans and/or cotton have higher productivity of pollinated crops than in municipalities that have planted soybeans and/or cotton, as well as to verify if the presence of forest remnants (habitat of native bees) favor the ecosystem service of pollination contributing to the productivity of crops essentially dependent on this service. The results suggest that the increase in the cultivation of Soy and Cotton in the Brazilian Midwest does not interfere in the productivity per hectare of the crops analyzed.Item Efeito da instituição da cobrança pelo uso da água na configuração agrícola irrigada em Cristalina-GO(Universidade Federal de Goiás, 2017-03-01) Furquim, Maria Gláucia Dourado; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Alves Júnior, José; Figueiredo, Reginaldo SantanaThe water availability to different user sectors and ecosystems, ensuring the quality, quantity and perpetuity of this resource for future generations, has been one of the challenges of public management, particularly in the sphere of River Basins committees. The present study is about the effectiveness of the institution of a fee, to be charged by the water use in the Paranaíba River Basin, with a forecast of charging from 2017. An exploratory and descriptive research was carried out to get information about the reality of irrigated agriculture in the county of Cristalina GO, which stands out nationally for having the largest area irrigated by central pivot of Latin America. Through the linear programming method, alternative scenarios were elaborated to the current configuration of land use by irrigated agriculture, resulting from the different collection values to be instituted gradually, starting in 2017, modeling the function/goal as a result of the maximum financial return given the restrictions on water availability and agricultural area. The results indicate that the fee will not imply a significant reduction of the total income of the irrigating producer to the point of instigating changes in the areas or cultures currently cultivated, however, the collected values are presented as a source of investments for the recovery/conservation of the water bodies of the basin itself .Item Políticas públicas e desenvolvimento rural sustentável: uma análise da efetividade do programa Bolsa Verde no Assentamento Canudos em Goiás(Universidade Federal de Goiás, 2016-05-25) Graciano, Monyele Camargo; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Almeida , Luiz Manoel de Moraes Camargo; Souza, Cleonice Borges deThis study sought to weave an analysis of the Bolsa Verde Program from its institutional axis, which are: environmental conservation, promoting citizenship, productive inclusion, eradication of rural poverty, and for the latter, it is important to make an alignment to the concept of food security. The overall objective of this research was to evaluate the effectiveness of the Bolsa Verde Program in Sustainable Development Canudos Settlement in the State of Goiás, in the 2012 period to 2014. To check these objectives, the methodology used in the work was a qualitative and quantitative approach, held field research, where we proceeded to the interviews and application forms. These forms took as guiding the Environmental Indicator (AI), the Brazilian Food Insecurity Scale (EBIA) and socioeconomic issues. Resettled 38 families were interviewed benefited from the Bolsa Verde Program . The work is structured by the introduction and three chapters. In the first chapter are the search paths and operating methods, the second is the theoretical work, addressing aspects of public policy, rural poverty, rural and sustainable development, food security, public policy in Brazil and foundations Program Green bag. In the third chapter, we proceeded to the analysis and discussion of the results collected in the field. It was noticed from the data that the Bolsa Verde Program has influence on levels of food security of beneficiaries as 50 % of respondents were in Food Insecurity Take 47% and Food Safety . However as environmental consideration the program presented evidence of inefficiency , since the levels measured by the Environmental Indicator predominantly were medium and low.Item Capital social na cadeia de produção agroindustrial do leite em Ipameri-Go(Universidade Federal de Goiás, 2016-03-12) Peixoto, Fernanda Gomes Kotinik; Abdala, Klaus de Oliveira; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4438722D5; Abdala, Klaus de Oliveira; Barbosa, Ycarim Melgaço; Wander, Alcido ElenorThis research had been developed to verify the level of social capital in the dairy agribusiness production chain in Ipameri – Goias, and to establish a linkage between that level and the sustainability of the production chain in the city. In this proposal, it was adopted the qualitative methodology of research with exploratory purpose. The following methodologies were used during this exploration: the social capital index, the municipal sustainable development index and the diagnostic analyses of the production chain. Moreover, this research aimed on contributing with the study of social capital in production chains, as it has not been verified a large number of studies in that area. The results showed that the agroindustrial production chain of milk in Ipameri has a low level of capital accumulation and that the environmental dimension should be better explored. In conclusion, the dairy production chain does not contribute to a sustainable development in the municipalityItem Aspectos valorativos do cerrado goiano como provedor das plantas medicinais para fins de uso tradicional: o caso do Grupo Espírita da Paz(Universidade Federal de Goiás, 2018-03-21) Sena, Carlos Eduardo Silva; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Abdala, Klaus de Oliveira; Ribeiro, Dinalva; Ribeiro, Francis LeeMedicinal herbs are important natural riches to several cultures, mostly because of their phytotherapic use originated from traditional knoledge aqcired through direct contact with nature. Given that relevance, to secure products’ quality and to boost the sector’s progress, a group of institutions developed themselves attending to the Política Nacional de Plantas Medicinais e Fitoterápicos (PNPMF), however, contradictorily, they stablish barriers to the production chain base constituted by strategic agents to the sector’s consolidation in Brazil. Besides, added to these barriers, when it comes to brazilian biomes, specially Cerrado, despite it’s composition by an abundant floristic diversity, that biome faces a scenario of land occupation due to agriculture advent, what sugests that services of medicinal herbs provision might be threatened. Therefore, this work highlights the value of the phytotherapy performed by Grupo Espírita da Paz as a critical point of sucsess on developing medicinal herbs production chain from income generation, cultural recognition and conservation of biomes that provide genetical resourses to phytotherapic herbs production, proposing a strategic guideline to the institutional improvement of the sector from this perspective.Item Sustentabilidade e produção orgânica: fazenda Nossa Senhora Aparecida em Hidrolândia-GO(Universidade Federal de Goiás, 2018-03-09) Sousa, André Chagas de; Abdala, Klaus de Oliveira; Fernandes, Paulo Marçal; Souza, Cleonice Borges deThis research sought to understand sustainability in the process of certified organic production, by the means of the study of a property with such certification, instituted by Law 10.831 and audited by IBD. Using a multi-method analysis, which integrated SWOT strategic planning methodology and Marco de Evaluación de Sistemas de Manejo Incorporando Indicadores de Sustentabilidad – MESMIS (Indicator-based Framework for Evaluation of Natural Resource Management. Systems), indicators were elaborated for the main organizational sectors of a well-established company in organic production: Marketing; Operations; Management Information System; Property Administration; Finance; and Human Resources. 31 indicators were worked out: 13 for the environmental dimension, 9 for the economic dimension, and 9 for the social dimension. They were measured by a semi-structured interview and questionnaires dealing with the following attributes: productivity, stability, resilience, and equity. The evaluation of the results served to identify the critical points and discuss them with the participants of the productive processes in the company. The MESMIS was essential to identify the indicators and allowed, besides measuring them, the possibility to describe them in a qualitative way. The method provides a participatory and interdisciplinary bias, as well as a systemic approach, integrating the attributes of sustainability and the environmental, economic and social dimensions, and, additionally, when applied in conjunction with the SWOT, it provides corrective measures to critical points. The results of the indicators of environmental dimension - 8.5, economic dimension - 7.7, and social dimension - 8.3 indicate that, with an aggregate value of 8.2, the property analyzed can be classified as "good" in relation to sustainability. On the other hand, results reached between the dimensions also display low average values. Indicators assessed as poor are: commercial product presentation - note 1,7 (economic); dependence on external resources - note 4,7 (economic); organic matter with origin in the property (%) - note 4,2 (ecological); diversity of alternative techniques - note 3,3 (ecological); satisfaction with public technical assistance - note 3,3 (social); persons occupied by ha (total of the productive unity) - note 5,0 (social); persons employed/ typical demanded days - note 6,0 (social). The research, in addition to its limitations, also demonstrated that the strategic analysis, starting from the SWOT Matrix, focusing on the organizational areas, and conducted by the MESMIS method, is an essential tool for the administrator to execute actions that improve the sustainability of the agroecosystem in which his/her venture is inserted.Item Trajetória da produtividade da soja em função da variabilidade das chuvas no estado de Goiás(Universidade Federal de Goiás, 2017-02-21) Vale, Najla Kauara Alves do; Ferreira, Marcelo Dias Paes; http://lattes.cnpq.br/3436824386339415; Figueiredo, Reginaldo Santana; http://lattes.cnpq.br/l098394550647665; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Wander, Alcido Elenor; Leão, CarlosThe conception that environmental factors, especially the weather, are one of the main constraints of the agricultural production development is in forced at the current days. In the soybean crop, the climate variability can affect the productivity variability, since the weather can have both positive and negative effects, according to the way it act. This ambiguity is responsible for losses in production, which, in the other hand, means that more technologies are being developed to minimize the negative climate impact, in order to mitigate losses and obtain significant economic gains. The technification of the soybean crop was one of the elements that allowed the expansion of the soy in the cerrado biome and, also provided the development of the agricultural sector in the state of Goiás, which nowadays occupies the fourth position in the national ranking of soybean production. However, even with the increment of new technologies, rainfall represents a restrictive factor to obtain high agricultural productivity, mainly because of the occurrence of climate variability in the state. When measuring the importance of the soybean crop in the state and the increasing concern with the loss of productivity due to the precipitation shunt, this following work had as general goal to understand the relationship between variability of rainfall and the soybean yield in the state of Goiás, between 1990 and 2008, attempting to answer the question: what is the contribution of technological evolution in terms of mitigating the effects of precipitation deviation on soybean yield in the state of Goiás? It is important to notice that several works already proved the intrinsic relationship between these variables, precipitation and productivity. In this study the main difference is the use of an econometric model that aims to capture the technological advances and the increase in the use of agricultural inputs, evaluating if these variables are actually mitigating the effects of rainfall and increasing productivity over time.Item Dinâmica de serviços de regulação hídrica na bacia hidrográfica do ribeirão João Leite, Goiás(Universidade Federal de Goiás, 2019-03-28) Vitoria, Mariane Rodrigues da; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Abdala, Klaus de Oliveira; Griebele, Nori Paulo; Medina, Gabriel da SilvaRelations that touch the environment and economic issues do not always coexist in a reconciled way. In this sense, several mechanisms were introduced in Brazil, such as the forest code with the purpose of prescribing the APPs and the Legal Reserve, both as the objective of guaranteeing the maintenance of environmental services, in addition to the emergence of projects and programs involving the Payment of Services (PSA) with the objective of rewarding environmental service providers, such as the National Water Agency (ANA) Water Producer Project (PPA), which aims to reduce erosion processes in agricultural areas and to recover water sources . This program is part of a decision-making model that takes into account the various economic, social and environmental aspects in the area of interest, using market instruments to produce positive stimuli in the behavior of agents responsible for changes in ecosystem functions. In this sense, despite the efforts, studies that quantify the economic benefits of environmental services are still scarce, so that they are included in decision-making. The objective of this study was to quantify and evaluate the hydrological environmental services in the João Leite Goiás river basin, as well as in its sub-basins, through environmental modeling. The SDR model of the InVEST (Integrated Valuation of Environmental Services and Tradeoffs) package was used in order to simulate the sediment flow in some scenarios: previous scenario, during and after the Water Producer program. Finally, a valuation of the environmental services was carried out, as a way of estimating the costs avoided with dredging and soil recomposition. Costs that were compared to the opportunity cost of the program. In relation to the results presented by InVEST, it was possible to see a reduction in sediment production, mainly soil loss (USLE) and sediments exported to the sub-basins, mainly in scenario II and future to which they were simulated with a more conservationist management, besides the practices proposed by the Water Producer program. Thus, the results showed the importance of projects such as the Water Producer, not only in improving environmental conditions, but mainly, would result in economic and social benefits. Small producers are one of the main beneficiaries due to the improvement in social and environmental conditions, although they are not the only ones, since the benefits go beyond the sub-basin's limits, such as in the water supply to the RGM. Finally, the participation of agribusiness as a funder of projects such as the PPA, aimed at the restoration, protection and conservation of natural resources, conscious of the value (not only of money but also of the intangible value of natural resources such as water and soil) is of extreme importance. This value can be measured when one considers that the sector presents a negotiation framework with the different markets, among them the international market, which can stand out as a producer of ecosystem services - not just commodities.
