The Brazilian Exclusive Economic Zone, or the "Blue Amazon", with its extensive maritime area, is the primary means of transport for the country's foreign trade and is important due to its oil reserves, gas and other mineral resources, in addition to the significant influence on the Brazilian climate. We have manually built a question answering (QA) dataset based on crawled articles and have applied an off-the-shelf QA system based on a fine-tuned BERTimbau Model, achieving an F1-score of 47.0. More importantly, we explored how the proper visualization of attention weights can support helpful interpretations of the system's answers, which is critical in real environments.

Bangladesh and India sea boundary talks started in 1974, renewed in 1978 and in 1982. At last, the Hauge-based Permanent Court of Arbitration (PCA) gave verdict on July 07, 2014 on maritime disputes between India and Bangladesh. In a landmark judgment, the Permanent Court of Arbitration (PCA) awarded Bangladesh an area of 19,467 sq km, four-fifth of the total area of 25,602 sq km disputed maritime boundary in the Bay of Bengal with India. Now, Bangladesh’s maritime boundary has been extended by 118,813 sq km comprising 12 nm of Territorial Sea and an EEZ extending up to 200 nm into the high sea. In addition, the ruling acknowledged Bangladesh’s sovereign rights of undersea resources in the continental shelf extending as far as 345 nm in the high sea, taking Chittagong coast as the baseline. Now, Bangladesh can go ahead with their plans of search and extraction of energy and mineral resources and exploitation of fisheries within 200 nm from the baseline. The study tries to identify the various rights of Bangladesh over various maritime zones such as Territorial Sea, Contiguous Zone, Exclusive Economic Zone and Continental Shelf on the basis of the Bangladesh v India case (2014).

Mineral resources and energy are central to the level of technological sophistication that we have come to expect in our everyday lives. Yet the availability and use of these finite resources is unsustainable, almost by definition, and particularly so when considering fragile ecosystems. This raises the ‘super-wicked’ policy issue, negotiated through resource management legislation, of trying to balance necessary resource use with not irreparably damaging the natural environment (Levin et al., 2012). This article primarily concerns the effects of the Resource Legislation Amendment Bill (2015) on management of the exclusive economic zone (EEZ) and continental shelf area. Omnibus bills that contain nontechnical and contentious amendments continue to challenge civil society’s ability to fully consider the implications of reform.
