Abstract:
... Assessing the economic importance of traits is crucial for delivering appropriate breeding goals in dairy cattle breeding. The aim of the present study was to calculate economic values (EV) and assign the importance of health traits for three dairy cattle breeds: Lithuanian Black-and-White open population (LBW), Lithuanian Red open population (LR) and Lithuanian Red old genotype (LROG). The EV est ...

Abstract:
... Addressing serious grassland degradation without exacerbating already low herder incomes is a major challenge for the Chinese government. In response, the Grassland Ecosystem Subsidy and Award Scheme (GESAS) was introduced in 2011 where herders receive payments if they comply with specified stocking rates set at more sustainable levels. However, compliance with GESAS, as well as low herder incomes ...

Field data from commercial flocks can inform sensitivity analyses of the effect of litter size on flock productivity, feed demand, and gross margin. This study adapted an established bio-economic model of a flock of breeding ewes informed by statistic ...

Abstract:
... The study assesses the conservation and fisheries benefits of the Blue Bay Marine Park in Mauritius. It addresses the question - are the higher catch rates near the Park a result of population spillovers or of reduced fishing effort in those waters due to site-specific attributes? There is no data on catches and fishing effort prior to the reserve's establishment; a bioeconomic model is used to se ...

... The selection index methodology is the best approach to increase profit in animal production by genetic selection due to the use of economic values for breeding goals. The aim of this study was to derive economic values through a deterministic bio-economic model in order to construct an economic selection index for dual-purpose Simmental cattle. Phenotypic, genetic and economic information from th ...

Abstract:
... In animal breeding, genetic parameters along with economic weights (EWs) of traits are applied. Profit functions currently used to calculate rabbit traits’ EWs do not consider nutrient requirements based on animal weight, growth rate and doe reproductive status. Therefore, the aim of this study was to develop a flexible bioeconomic model of rabbit-production systems and implement it in a computer ...

Balancing these objectives is made more complex in the case of multispecies and multigear fisheries.

Abstract:
... About half of the households in the mid-hills of Nepal are severely food insecure, and the development of agriculture and forestry sectors could hold keys to reduce food insecurity and achieve other sustainable development goals. This paper presents results from a bio-economic model, Enhancing Livelihood from Improved Forest Management in Nepal (EnLiFT), that estimates a Food Security Index (FSI) ...

Abstract:
... In this study, we developed a bio-economic model coupling land use and ecosystem services to investigate the role of forests on a broad set of ecosystem services, including carbon sequestration, soil quality and biodiversity. As a case study, the model was calibrated with economic, agronomic and ecological data from the Torrecchia Vecchia agroecosystem in Italy. In our analysis of optimal land use ...

Abstract:
... With intensification, Asian seabass are prone to infectious diseases such as vibriosis that could lead to additional costs in the grow-out cage culture system. Other costs include feeds, fingerlings and antibiotics. To improve awareness to the costs, the objective of this study is to estimate the costs of Asian seabass that include endemic vibriosis. First, farm-level costs were estimated using a ...
