Análise econômico-financeira de um sistema de cultivo hidropônico: um estudo de caso para a Ilha de São Luís, Maranhão.

Abstract

The region of the Island of Sã o L uís, Maranhã o, faces significant challenges for conventional agriculture, such as water seasonality and low natural soil fertility, which compromise food production and accentuate food insecurity. This study's main objective was to analyze the economic-financial viability of a 240 m² NFT hydroponic cultivation system, with an annual production capacity of 36,960 plants, for the production of leafy vegetables as a sustainable alternative for the region. The methodology was based on a case study, with a survey of implementation and operational costs from budgets of a specialized company and price research in the local market. The financial indicators of Net Present V alue (NPV ), Internal Rate of Return (IRR), Discounted Payback, Profitability Index (PI), and Break-Even Point were used, with a Minimum A ttractive Rate of Return (MA RR) of 15,04% per year as a parameter. The results demonstrated the investment's attractiveness, with a positive NPV of BRL 31,685.16 and an IRR of 24.52%. The return on invested capital was estimated at 3 years, 9 months and 4 days, and the break-even point was reached using only 38.4% of the production capacity, providing a high safety margin for the business. It is concluded that the project is economically viable and financially attractive, presenting itself as a robust and profitable alternative for producers seeking innovation and sustainability in the production of vegetables on the Island of Sã o L uís.
