The Scheldt estuary is exposed to large loads of carbon and nutrients. This leads to a eutrophication problem characterized by reduced oxygen concentrations and a huge efflux of CO<sub>2</sub>. In the coastal waters a degradation of the foodchain is noted caused by excessive nutrient supply. The capacity of the estuary to polish the water is important but can not cope with the vast scale of the immissions. Restoration and development of tidal wetlands can contribute in several ways to restore the water quality. Increase of water treatment is expected to have positive ecological results. Nevertheless, restoration of the oxygen conditions might counteract some purifying processes. |

E-commerce's value creation in agricultural and food markets will only occur to the extent that e-commerce firms exist throughout the supply chain. The problem is that e-commerce firms throughout the agricultural and food supply chain have faced a serious challenge in staying in business. Many have been forced to exit the market, and only a few have survived to develop into functional web-based businesses. The objective of this research study is to identify characteristics that are associated with successful e-commerce firms throughout the agricultural and food supply chain. Relevant e-commerce and agricultural e-commerce literature suggests several characteristics that influence the success for agricultural and food e-commerce firms. A limited-dependent... |

ABSTRACT: Short Food Supply Chains (SFSCs) provide a dependable substitute for conventional supply chains, as their food reflects the characteristics of “local”, “natural”, “healthy” and “reliable”. For the family farmer, the short chains constitute anexcellent way of diversifying their produce, gaining higher added value and thus warranting steadier revenues. This paper thus aims to discern the distinguishing features that the short chains offer, in general, to the family farm. To accomplish this, a literature review was performed to study the works done and approaches conducted on the short chains in the academy, in terms of family farm, and identify their specifications. Positive characteristics related to family farmers were recognizable in comparison... |
