The aim of the chapter is to show the possible impact of policulture farming on some determinants of sustainable agricultural development, especially from the point of view of economic viability, biodiversity, and land degradation. Increasing the area under polyculture is one of the main solutions to the present environmental problems. The key constraints are economic pressures due to the question of the cost-effectiveness of such a mode of production and the need to provide sufficient food for a growing population, especially in developing countries. The results of the research show that policulture (organic agriculture) should be favored, while monoculture farming must be adequately directed and put in the function of achieving ecological goals of sustainable development as much as possible. In addition, on the example of European countries, it was assessed that there are good conditions for further “greening” of agriculture, bearing in mind the movement of the analyzed indicators.

Abstract Objectives Estimating the maximum acceptable cost (MAC) per screened individual for low-dose computed tomography (LDCT) lung cancer (LC) screening, and determining the effect of additionally screening for chronic obstructive pulmonary disease (COPD), cardiovascular disease (CVD), or both on the MAC. Methods A model-based early health technology assessment (HTA) was conducted to estimate whether a new intervention could be cost-effective by calculating the MAC at a willingness-to-pay (WTP) of €20k/quality-adjusted life-year (QALY) and €80k/QALY, for a population of current and former smokers, aged 50–75 years in The Netherlands. The MAC was estimated based on incremental QALYs gained from a stage shift assuming screened individuals are detected in earlier disease stages. Data were obtained from literature and publicly available statistics and validated with experts. Results The MAC per individual for implementing LC screening at a WTP of €20k/QALY was €113. If COPD, CVD, or both were included in screening, the MAC increased to €230, €895, or €971 respectively. Scenario analyses assessed whether screening-specific disease high-risk populations would improve cost-effectiveness, showing that high-risk CVD populations were more likely to improve economic viability compared to COPD. Conclusions The economic viability of combined screening is substantially larger than for LC screening alone, primarily due to benefits from CVD screening, and is dependent on the target screening population, which is key to optimise the screening program. The total cost of breast and cervical cancer screening is lower (€420) than the MAC of Big-3, indicating that Big-3 screening may be acceptable from a health economic perspective. Key Points • Once-off combined low-dose CT screening for lung cancer, COPD, and CVD in individuals aged 50–75 years is potentially cost-effective if screening would cost less than €971 per screened individual. • Multi-disease screening requires detailed insight into the co-occurrence of these diseases to identify the optimal target screening population. • With the same target screening population and WTP, lung cancer-only screening should cost less than €113 per screened individual to be cost-effective.

Abstract The growth of Brazilian floriculture is remarkable, both in terms of the number of producers and the cultivated area. To reduce costs and add value, the organic production of ornamental pineapple plants is an option for some consumer markets. This study was carried at the Fundação José Carvalho, municipality of Entre Rios (Bahia State), Brazil, to evaluate the economic viability of the organic production of ornamental pineapple plants, as well as to analyze the economic factors from implantation of the crop to the final production phase. Primary and secondary data collection (technical coefficients and prices) was carried out, which allowed updating the value of these coefficients. After determining the technical coefficients, input prices and product prices were surveyed and were inserted in spreadsheets of production cost and profitability. Data processing and profitability analysis were carried out under deterministic and risk conditions. The organic cultivation system for ornamental pineapples proved to be economically viable, providing greater profitability and production of stems, which is the product of interest.
