Summary: The study found that the international sweet cherry trade is highly concentrated in Europe, with producing countries divided into five groupings based on pest compositional similarities. Additionally, pest species richness linearly increased with production volume and were over-represented in specific countries with large import volumes. Ongoing regional and global cooperation is necessary to improve international regulations, especially for countries like China which have granted market permits to major producing countries posing a high risk for pest introduction and establishment.

Summary: This paper introduces the concept of trade-off ratio function and its relationship to proper efficiency in multi-objective optimization problems, exploring its boundedness property. For linear multi-objective optimization problems, the trade-off ratio function is shown to be bounded on the efficient solution set. In the case of piecewise linear multi-objective optimization problems, all efficient solutions are properly efficient and subject to a recession condition for proper efficiency in Geoffrion's sense.

Summary: I study the impact of import tariffs on labor demand and welfare distribution in an asymmetrical general oligopoly trade model. The anti-competitive effect of tariffs leads to a decrease in labor demand, favoring profit recipients over workers. Increasing import tariffs can improve domestic welfare at the expense of foreign countries, but negatively affects workers by lowering their real wages. Only when initial tariffs are low can the government use the revenue from increasing tariffs to neutralize the negative effects on workers or redistribute the benefits. However, tariffs do not seem to be a suitable tool for supporting workers in an oligopoly market.

Summary: Optimization methods are not commonly used in supporting species recovery programs, due to the difficulty in representing and optimizing complex multidimensional problems. However, a study demonstrates how integer linear programming can be used to solve such complex problems in reintroduction planning for the critically endangered Montseny brook newt, optimizing site restoration efforts, captive releases, and monitoring.

Summary: The study found that the occurrence of herbaceous flavor in Regina sweet cherries is mainly related to delayed ripening of cherries, the quantity and odor condition of volatile compounds, rainfall, and the elevation of orchards. To reduce the incidence of herbaceous flavor, preharvest practices that promote fruit ripening and avoiding early harvests are recommended.

Summary: Demand response (DR) is crucial for integrating variable renewable energy (VRE) sources. Detailed DR models are too complex for large-scale energy models, while aggregated DR models are too simplistic. This paper proposes a classification and modeling approach for DR in large-scale models, using linear constraints and a mixed integer programming formulation to capture the key effects of DR in the energy system.

Summary: The paper introduces a new interactive procedure based on trade-off analysis for solving stochastic discrete multiobjective programming problems with a finite number of stages, using project portfolio selection as an example. Despite the problem not being very large in size, its difficulty lies in the fact that projects are not implemented simultaneously.

Summary: This article studies the infinite-horizon adaptive optimal control of continuous-time linear periodic systems and proposes a novel value iteration-based off-policy adaptive dynamic programming algorithm for a general class of systems. The algorithm is proven to uniformly converge to optimal solutions in both model-based and model-free cases, without assuming knowledge of an initial stabilizing controller. Application to a triple inverted pendulum demonstrates the feasibility and effectiveness of the proposed method.

Summary: Global farmland biodiversity has decreased due to agricultural landscape homogenization, but restructuring landscapes by reintroducing woody features and decreasing field sizes can increase biodiversity and agricultural net returns. Using spatial multi-objective optimization, we demonstrate that reallocating woody features and adjusting field sizes can simultaneously increase both bird abundance and agricultural net returns. Taking into account location and farmers' willingness to accept negative impacts on net returns is crucial for achieving higher farmland bird diversity. Our spatially explicit approach supports targeted land use planning to balance economic objectives and biodiversity conservation.

Summary: Agricultural intensification is important for food security and limiting rural exodus in sub-Saharan Africa. Livestock farming has the potential to improve the sustainability of farming systems, but landscape-level studies are rare. By considering the interactions between animals, crops, and trees, the landscape level is the only level where the impacts of livestock farming can be fully understood. This study developed a methodology to compare different livestock systems based on territorial metabolism and sustainability indicators.

Summary: This study aims to evaluate the potential of South Asian agroforestry systems as a viable agroecological approach for ensuring farmers' food security. A systematic literature review found that out of 95 reviewed studies, only nine focused on food security and none of them examined all four dimensions of food security simultaneously. Moreover, the majority of studies were skewed towards the Himalayan belt and lacked quantitative measurement, making it challenging to determine the significance of this field.

Summary: Wheat production in the Terai region of Nepal has not met the increasing demand, with low average productivity and high spatial and temporal variability. This study identifies strategies for closing yield gaps through field surveys, on-farm experiments, and simulation models. The results suggest that improving agronomic practices, such as fertilization and irrigation management, can significantly increase wheat productivity.

Summary: This study integrates knowledge on the benefits and disbenefits of (semi)natural vegetation on farms for achieving six objectives, and develops a conceptual model of the relationships between these objectives and different types of vegetation. The results show that (semi)natural vegetation provides more benefits than disbenefits, with greater support for the benefits of native vegetation. Farm-level restoration contributes towards reversing vegetation loss, but the process takes time. Management practices play a role in enhancing the benefits of (semi)natural vegetation.
