Rentabilidade da Produção de Acerola Orgânica Sob Condição Determinística e de Risco: estudo do distrito de irrigação Tabuleiro Litorâneo do Piauí

Organic/biodynamic agriculture has been reported worldwide as a suitable system to conserve or even regenerate natural resources. Due to the lack of long-term studies regarding the profitability of tropical organic vs conventional farming, the economic performance of biodynamic vs conventional soybean was studied using data from a consecutive 7-yr case study in a farm with 48.4 ha of biodynamic soybeans in Paraná State, Brazil. Analyses of production costs and financial indicators were adjusted at updated values according to inflation in the period. Effective operational costs were 4.4% higher in biodynamic than in conventional farming. The biodynamic yields were lower (3.6%) than those of conventional. Prices were 57% higher in biodynamic than in conventional, making biodynamic farming more profitable than conventional farming, as shown by financial indicators (gross revenue, gross margin, net margin, net income and capital income were 50.7, 99.9, 122.9, 150.4 and 166.9%, respectively, higher in biodynamic than in conventional). The price equilibrium point (PEP) was 3.4% higher for biodynamic farming; the leveling point was 36.9% higher for conventional farming. Manual weeding and plowing increased organic costs. Higher biodynamic trading prices than those of conventional triggered a PEP suitable for covering higher costs and thus boosting profitability. Further investigations and policies are suggested to further improve biodynamic farming efficiency and sustainability.

“…According to Martins et al (2016), this analysis identifies the variables that determine the success of the project but does not measure the risk associated with these variables. Considering that any economic feasibility study always has an inherent uncertainty factor, and the sensitivity analysis does not escape this rule, a risk analysis must be performed after completing the sensitivity analysis.…”

“…According to Martins et al (2016), MCS applies well to non-probabilistic problems and those with inherently probabilistic structure. Also noteworthy, the advantage over other numerical methods, which have n-points of evaluation in an m-dimensional space to produce approximate solutions, the fact of obtaining the absolute error of their estimates decreasing to n-1/2, while all the others have an absolute error of estimate decreasing to n-1/m at most.…”

Economic viability of ‘Niágara Rosada’ grape production in the north and northwest regions of Rio de Janeiro

The ‘Niágara Rosada’ grape (Vitis labrusca) is the main table cultivar produced in the North and Northwest Regions of the Rio de Janeiro State. This cultivar presents greater rusticity and lower production cost than the cultivars of fine grape (Vitis vinifera L.) because it is more resistant to diseases and the absence of some cultural treatments. The research aimed to determine the economic affordability of the production of ‘Niágara Rosada’ grapes in the north and northwest regions of Rio de Janeiro state, by calculating the Net Present Value (NPV) and the Internal Rate of Return (IRR), and to identify the risk of viticulture, through the sensitivity analysis and the use of the Monte Carlo method. To collect the data, questionnaires, and interviews were applied directly to the wine producers on the technical coefficients and respective production costs of the grape in 1 ha. The results highlighted that viticulture could be a good alternative for the regions, with satisfactory profitability. The variables with the most significant effect on profitability were the sale price of the product, the cost of labor, and the price of packaging. The probability of winegrowers to obtain a negative NPV is 33.32%, considering an attractiveness rate of 6% per year.

“…No intuito de expandir a quantidade de informações para tomada de decisão, frequentemente se utiliza simulações de Monte Carlo, como nos estudos de Melo, Silva e Esperancini (2012), Miguel, Esperancini e Grizotto (2014), Liu et al (2017), Martins et al (2016) e Stott et al (2018). Este método, desenvolvido por Hertz (1964), considera que o padrão de ocorrência de um evento segue distribuição de probabilidade.…”

Agradeço primeiramente a Deus, por se constituir em força maior, fonte de fortaleza, esclarecimento e saúde. Em seguida, à minha mãe Dri, meu pai Davi e minha irmã Lala, por se mostrarem compreensivos em todos os momentos. Devo a eles minha formação, antes de tudo como ser humano, e carrego em mim um pouco de cada um.Agradeço também à minha namorada Thaís, pela compreensão ao longo de todo o mestrado, por seu amor e fidelidade, e pela presença dia após dia, mesmo a quilômetros de distância. Agradeço à minha família em maior amplitude, avós, tios e primos, companheiros naturais do ser humano, ainda que por encontros eventuais, estando sempre em meus pensamentos.Serei eternamente grato ao meu orientador e professor Lucilio R. A. Alves, por me acolher e proporcionar a oportunidade de conviver em um ambiente de excelência em pesquisa, além de seus esforços dispendidos em ensinamentos e análises minuciosas. Sem dúvida tem sido um momento de grande desenvolvimento pessoal e profissional, e levarei para a vida o conceito de que devemos sempre nos esforçar para atingirmos nosso melhor desempenho, com seriedade, ética e perseverança.
