Exploitation of transboundary oil and gas on continental shelves may cause conflicts between or among States concerned due to the physical character of these resources. As oil and gas are fluid, exploitation of such a transboundary oil field by one side may affect other parties in other jurisdictions. However, there is no universal international legal regime on the issue. This article tries to find the international legal regime governing such resources through analysing UN Assembly's resolutions, UNCLOS, international judicial opinions, bilateral agreements and ILC activities relating to transboundary natural resources. As a result of this study, it seems that each coastal State has an inherent sovereign right on its part of the transboundary oil and gas deposit, but this right is not unlimited. Each state involved with the deposit has a duty to cooperate with other states-through information exchange, consultation, and negotiation. Furthermore, the state has an obligation to refrain from unilateral action when there is a possibility of causing irrevocable damage to the interests of the other states.

The impacts of dams on transboundary flow are complex and challenging to project and manage, given the potential moderating influence of a broad range of anthropogenic and natural factors. This study presents a global meta-analysis of 168 studies that examines the effect magnitude of dams on downstream seasonal, annual flow, and hydrological extremes risk on 39 hotspot transboundary river basins. The study also evaluates the impact of 13 factors, such as climate, basin characteristics, dams' design and types, level of transboundary cooperation, and socioeconomic indicators, on the heterogeneity of outcomes. The findings reveal that moderators significantly influence the impact of dams on downstream flow, leading to considerable heterogeneity in outcomes. Transboundary cooperation emerges as the key factor that determines the severity of dams' effect on both dry and wet season's flows at a significance level of 0.01 to 0.05, respectively. Specifically, the presence of water-supply and irrigation dams has a significant (0.01) moderating effect on dry-season flow across basins with high transboundary cooperation. In contrast, for wet-season flow, the basin's vulnerability to climate extremes is associated with a large negative effect size. The various moderators have varying degrees of influence on the heterogeneity of outcomes, with the aridity index, population density, GDP, and risk level of hydro-political tension being the most significant factors for dry-season flow, and the risk level of hydro-political tension and basin vulnerability to climate extremes being the most significant for wet-season flow. The results suggest that transboundary cooperation is crucial for managing the impacts of dams on downstream flow, and that various other factors, such as climate, basin characteristics, and socioeconomic indicators, have significant moderating effects on the outcomes. Thus, context-specific approaches are necessary when predicting and managing the impacts of dams on transboundary flow.

방글라데시는 인도히말라야와 인도차이나 경계에 위치한 아열대 몬순기후지역이며 생물다양성 핫스팟으로 알려져 있다. 식생은 활엽수림, 침엽수 및 혼효림으로 구성되어 있으며 습지와 망그로브로 이루어져 있다. 자연경관은 많은 강과 해안선 및 언덕과 농업 산림으로 이루어진 수려한 경관이다. 전 세계적인 선라반이라 불리는 망그로브가 있으며, 이 지역은 방글라데시와 인도 중간에 위치하고 있으며, 1999년 유네스코 세계자연유산지역이다. 망그로브의 62%가 방글라데시에 위치하고 있으며, 많은 동식물이 존재한다. 그러나 많은 사람으로 인해 자연환경이 변화고 있으며, 벌채림이 증가하고, 자연서식자가 감소된다. 이런 이유로 많은 종이 멸종에 처하게 되고 사라진 종도 많다. 이 지역 사람들은 직간접적으로 자연자원에 이익을 얻게 되며, 현재 생태관광이 주 수입원이다. 자연자원의 보호를 위해 정부는 각종 법령을 제정하고 있으며 많은 NGO가 생물다양성과 생태계 보전을 위해 노력하고 있다. 그럼에도 불구하고 현재 접경지역을 통한 오염물질과 자연재해는 방글라데시의 큰 위협요인이다.
