The extended continental shelf: A geographical perspective of the implementation of article 76 of UNCLOS
Abstract The delimitation of the outer edge of the continental margin beyond 200 nautical miles is paving the way for areas where States exercise rights of sovereignty to be extended when their geographical locations with respect to the continental margin allows it. Sixty-one submissions and forty-five preliminary reports, involving a total of ninety-one States (submitted to 31.07.2001), enable some of the geopolitical consequences to be outlined. Amongst those that can be highlighted are sometimes substantial changes in States' territorial bases and economic potential, and the global balance between national and international jurisdictions. This article uses regional and global scale maps based on national reports deposited with the Commission on the Limits of the Continental Shelf (CLCS) to present the main geographical and geopolitical findings. The geographical analysis similarly enables a quantitative estimation to be made of the effects of jurisdictional expansion on the “global commons”, of insularity and of the territorial gains made by the States concerned.
Living on the Margin in the Anthropocene: engagement arenas for sustainability research and action at the ocean–land interface
The advent of the Anthropocene underscores the need to develop and implement transformative governance strategies that safeguard the Earth's life-support systems, most critically at the ocean–land interface — the Margin. The seaward realm of the Margin is the new frontier for resource exploitation and colonization to meet the needs of coastal nations and humanity overall. Here, we spotlight the pivotal role of the Margin for planetary resilience and sustainability, highlight priority issues, and outline a research strategy which aims to: (a) better understand Margin social-ecological systems; (b) guide sustainable development of Margin resources; (c) design governance regimes to reverse unsustainable practices; (d) facilitate equitable sharing of Margin resources; and (e) evaluate alternative research approaches and partnerships that address major Margin challenges.
Linear Programming in the Allocation of Milk Resources for Cheese Making
Abstract To use linear programming, the cheese making process can be modeled as a resource conversion process. The relationship between input milk resources and output products can be analyzed using mass balance assumptions. The variables used in the linear programming model will represent the pounds of each milk resource chosen to formulate a vat of cheese milk. Additional variables will be used to represent the pounds of cream to be removed from a milk resource that has the potential to have cream removed. Three objectives that could be considered are 1) maximize net returns, 2) maximize cheese yield, or 3) minimize cost. A hypothetical example is used to illustrate how the cheese making process can be modeled. This linear programming model depends on formulas that relate ratio of casein to fat of milk to the fat on the dry basis of the cheese. Sensitivity analysis is performed to determine at what cost a milk resource not in the optimal formulation will replace a milk resource currently in the optimal formulation. The linear programming model can be an effective management tool in the allocation of milk resources for cheese making.
