The main objective of this paper is to analyze the relationships between the productive process and the commercial trade with water resources used by them. For that the goal is to find out, by means of the estimation of water embodied in the exported crops which have the highest export competitiveness and lower water consumption. The finding contradicts not only the comparative advantages theory but also the resources sustainability logic. This conclusion is derived from the great exports of water via tomatoes and low profitable vegetables from producers' perspective but not economical from social perspectives as shown in domestic resource coefficient. The diversion between financial and economic profitability is due to heavily irrigation water subsidy. The results confirm that Jordan utilizes large amounts of water in its exports, and in turn, it does not export goods with low water requirements. The potential saving would be very significant and agricultural sector need to modify the use of water to a great extent in order to reach significant water savings and an environmental sustainability. Jordan has to implement policies that reduced, or even abandoned, the export and the production of water-intensive crops. Therefore, they have to be replaced with either imports or crops that optimize the water resources. 展开更多

The paper proposes a matrix-based approach that a designer can use to evaluate the sustainability of one or more design solutions in the conceptual phase of a product development process. The methodology is structured in two main phases. In the first one, a data structure, called Augmented-DSM (Design Structure Matrix), has to be drawn in order to collect design information such as functional links among product components, indicators that provide information about the life cycle of each element, connections with the environment and toward other systems. The matrix is based on a DSM format, where new records were introduced to store and organize different types of data and an editing protocol was formalized. In the second stage, a set of procedures have to be applied in order to evaluate sustainability of a design solution and compare it with the others. The presented procedures, in fact, allow designers to assess a product in its proper characteristics, evaluate a device during its use stage and verify the coherence of links present in the functional model. This new approach is conceived to manage different performance indicators and, as a support tool, it is an attempt to aid designers in a quantitative evaluation. 展开更多
