Coupled with the obesity epidemic, food insecurity presents a public health and social crisis. The United States’ industrialized food system embodies an unsustainable network of production and unequal distribution of food creating threats to both the natural environment and human development. Ecological, economic, and social systems are interdependent and their relationships to food security ar...

It is expected that freight transport in the European Union will grow significantly and road transport will account for a major part of this growth. By 2020 almost 30% of CO2 emissions in the European Union will be caused by transportation. It is obvious that our present patterns of transport growth are unsustainable. One way toward more sustainable transport is to explicitly take greenhouse ga...

In the framework of ethical social choice theory, sustainability is justified by Efficiency and Equity as ethical axioms. These axioms correspond to the Suppes-Sen Grading principle. In technologies that are productive in a certain sense, the set of Suppes-Sen maximal utility paths is shown to equal the set of non-decreasing and efficient paths. Since any such path is sustainable, Efficiency an...

This article reflects on the recent unsustainable land use changes in the Autonomous Community of Madrid and asserts the need for progress towards economically, environmentally and socially sustainable development models. Following research undertaken over the last six years there are encouraging signs of agreement between stakeholders and the problem has begun to “open up”. Here a new phase of...

Sustainable Development (SD) is a global role model that claims to function as a general orientation for shaping societal processes, i.e., local, regional, national and international development. This is in line with the Brundtland and justice-oriented understanding of the term. It is understood as a role model and sometimes also interpreted as a regulative ideal. However, it does not state how...

In this opinion paper, I argue that “optimization and sustainable development” indicates a set of specific engineering techniques rather than a unified discipline stemming from a unique scientific principle. On the other hand, I also propose a mathematical principle underlying at least some of the concepts defining sustainability when optimizing a supply chain. The principle is based on the fac...

Many conventional practices in the production and use of water, energy, and food are unsustainable. Existing technologies and concepts can be improved with the integration of forward osmosis, a membrane-based technology that uses osmosis as its driving force. This Feature highlights five emerging applications of forward osmosis that elegantly bypass the difficult step of draw solution regenerat...

this paper, i have focused on the tax side of the fiscal policy to  investigate the past and future behavior of fiscal sustainability in iran. to do so, i have employed two different forward-looking and backward-looking approaches. first, the backward-looking approach is the fiscal policy rule proposed by daving & leeper (2011). precisely, this rule determines that whether the fiscal policy is ...
