“…According to Viana et al (2022), the agricultural sector increasingly requires the inclusion of techniques that minimize production risks and increase productivity to meet the global demand for food. In this sense, irrigation is a great ally of The P1 treatments showed negative profits in rainfed systems and even more negative profits in irrigated systems for both crops (Table 6).…”

The objective of the present work was to perform an economic analysis of centre-pivot irrigation implantation on a sandy soil area with different previous land uses. Thus, it was possible to analyse three initial soil conditions inside (irrigated) and outside (rainfed) the centre pivot. The opening area (P1) was characterized by soybean planting for the first time after degraded pasture, P2 consisted of the second year of harvesting soybean/maize second season, and P3 consisted of the third year of harvest. Two crops were evaluated: soybean and maize. The centre-pivot irrigation system was not profitable at the earliest stage of soil recovery (P1) immediately after degraded pasture because soil fertility limited yields. There was a 23% and 33% increase in soybean yield for the areas with 2 years (P2) and 3 years (P3) of soil recovery, respectively, compared to the first year. However, second-season maize had an increased yield of 19% for the third-year area (P3) compared to the first year (P1).

To expand financial knowledge and promote the socioeconomic sustainability of agricultural production systems, this work applied financial instruments to small-scale irrigated crops, making use of agricultural projects from the Bom Sucesso/Santa Cruz Settlement, located in the Tocantins-Araguaia basin, Brazil. The economic viability indicators of two irrigated okra production systems (furrow and drip) were calculated using the following indicators: Net Present Value, Modified Internal Rate of Return, Cost–Benefit Index, Discounted Payback, and Average Cost of Production. And a risk assessment through sensitivity analysis, a tornado chart, and Monte Carlo simulation was performed in a simplified financial model. The economic viability results showed that both irrigated systems were economically viable, although the okra drip system had lower indicators and reduced financial resilience, with a 58% probability of success, while the furrow system’s was 89%. The crops’ financial return was mainly influenced by okra’s sale price and productivity, followed by harvesting and planting costs. The financial tools applied in this study demonstrated some key factors to assess socioeconomic sustainability, such as the necessity to increase producers’ organizational capacity and to achieve technical improvements, which could result in market power, competitive sale prices, lower input costs, and greater productivity. The applied instruments increased financial management and have the potential to the build economic and social strength in the area of small-scale irrigated crops, and they can be replicated using simplified tools for producers, companies, and policy makers.
