Ornamental production worldwide has changed dramatically in the past 20 years. A globalized scene has shifted production to new countries from Africa, Asia, and South America. Sustainability is the major challenge for ornamental production, and the life cycle assessment (LCA) provides insights on environmental contributions from production to handling and transportation and highlights the problematic issues that need improvement. For example, greenhouse gas (GHG) emissions and the production costs of roses in different parts of the world may vary dramatically between different production processes (e.g., heated or non-heated greenhouses, with or without air transportation, etc.). On the other hand, the production of landscape plants has the lowest environmental impact of all floricultural products. Their long production period offers carbon sequestrations that reduce the total GHG emissions. Sustainability is achieved via critical adjustments on cultivation by minimizing fuel and electricity use, adopting integrated nutrient management (INM) and integrated pest and disease management (IPDM), and using recyclable materials and peat-alternative growing compounds. In this review, two possible scenarios were proposed for ornamental production. Scenario I suggests conventional, protected cultivation under controlled environments (i.e., greenhouses), which can be sustainable after implementing appropriate adjustments to reduce environmental outputs. Scenario II suggests the cultivation of native and specialty ornamental crops, which may serve as eco-friendly alternatives. Combinations between the two scenarios are also possible in view to implement sustainable practices and meet future consumer needs.

“…Decision analysis procedures would thus greatly benefit from improved mechanisms to identify a preferable option even in a context of high residual uncertainty. So far, this initial call has usually been based on the concept of expected value of the outcome variable (Luedeling et al 2015;Wafula et al 2018;Whitney et al 2017;Ruett et al 2020), but this concept is ignorant of decision makers' attitude toward risk, which features prominently in many decision-making processes. To add nuance to the initial evaluation on which decision option should be preferred, we ranked the outcomes of the strategies using stochastic dominance.…”

“…Additionally, we note here that when distributions are derived from a Monte Carlo analysis, analysts may also consider basing their evaluation on the distribution of differences between options among the model runs rather than on separate outcome projections for each option (as in Ruett et al 2020). This pointwise difference of binary relations between probability distributions is a numerical (monetary in our case) approximation for quantifying the magnitude of the dominance between distributions regardless of the stochastic orderings or dominance rules.…”

Profitability of farm-scale management strategies against the boll weevil in the tropics: case study from the Colombian Caribbean

Decision making in pest management is a challenging task. While pest dynamics are often quite uncertain, such decisions are often based on tenuous assumptions of certainty (economic injury levels and marginal utility approximations). To overcome such assumptions and adequately consider uncertainty, we apply decision analysis to evaluate management strategies used by farmers in the Colombian Caribbean against the boll weevil (BW). We represent the decision to protect the crop using partial budget analysis. This allows us to capture key properties of BW control strategies, while accounting for uncertainty about pest infestation pressure, control effectiveness and cotton yield and price. Our results indicate that proactive pest management is more efficient than reactive control given the current BW infestation pressure. However, farmers may prefer the reactive strategy, since they have experienced seasons with low infestation pressure where no insecticide applications were required. The proactive strategy, in contrast, requires scheduled pesticide applications in all years. Results show that in seasons with high infestation pressure the expected revenues of the reactive strategy tend to decrease, mainly because more spray applications are required when fields are heavily infested by the weevil. Value of information analysis revealed that uncertainties related to the start of the infestation, loss damage rate and attainable yield have the greatest influence on the decision recommendation for crop protection. Narrowing these key knowledge gaps may offer additional clarity on the performance of the current management strategies and provide guidance for the development of strategies to reduce insecticide use. This is particularly important for the promotion of the proactive strategy, which, under the current infestation pressure, has potential to reduce insecticide use. While economic injury levels can only be applied to responsive measures, our approach of partial budget analysis under uncertainty allows us to assess and compare both responsive and preventive measures in the same methodological framework. This framework can be extended to non-pesticide control measures.

Qualitatively grown planting material of introduced plants will further reduce the environmental risks of using agrochemicals and means of protection, and improve the living condition [8][9][10][11][12]. The objectives of the study included an analysis of the vital state of flowering shrubs grown using traditional and biologized technology; assessment of damage to flowering shrubs by entomo-and phytopathogenic objects in an urbanized environment.…”

The key to the normal growth and development of flowering shrubs is to provide optimal living conditions in the juvenile period. Obtaining high-quality planting material in a nursery using biologized techniques is a fundamental component of their future resistance to a complex of abiotic and biotic factors. The use of vermicompost (6 t / ha) as a fertilizer base and biologically active substances contributed to the production of high-quality seedlings. The applied biologic techniques contributed to the improvement of the growth and development of flowering shrubs, which influenced the reduction of damage by pests and diseases, the formation of healthy, decorative and attractive plants. Based on the analysis of the vital state, we ranked flowering shrubs according to their prospects for use in landscape design of the territory of urban ecosystems. Promising species for landscaping urban ecosystems in terms of a set of indicators are: Berberis thunbergii DC., Chaenomeles japonica (Thunb.) Lindl.), Lonicera caprifolium L., Physocarpus opulifolius L., Philadelphus coronaries L., Sorbaria sorbifolia L., Syringa velutina L. и Weigela florida DC.
