This piece analyses the recent judgment from the Makhanda High Court in Sustaining the Wild Coast NPC v Minister of Mineral Resources and Energy setting aside the decision to grant Shell and Impact Africa an exploratory right. Shell and Impact Africa intended to conduct a seismic survey along South Africa’s Wild Coast. Such a survey stood to have a substantial impact on the rights and interests of several local communities residing along the coastline. Because Shell, Impact Africa and the Director-General of the Department of Mineral Resources and Energy failed to consider these rights and interests, the court decided to overturn the decision granting the companies their exploratory right. To this end, the judgment provides a powerful vindication of the rights of local communities, illustrating what is possible when regulatory schemes are applied purposively and not as a mere box-ticking exercise.

Lake-level changes inferred from seismic surveying and core sampling of the floor of Lake Baikal near the Selenga River delta can be used to constrain regional climatic history and appear to be correlated to global climate changes represented by marine oxygen isotope stages (MIS). The reflection pattern and correlation to the isotope stages indicate that the topset and progradational foreset sediments of the deltas formed during periods of stable lake levels and warm climatic conditions. During warm stages, the lake level was high, and during cold stages it was low. The drop in the lake level due to cooling from MIS 5 through MIS 4 is estimated to be 33–38 m; from MIS 3 through MIS 2, it fell an additional 11–15 m. Because the lake level is chiefly controlled by evaporation and river input, we infer that more water was supplied to Lake Baikal during warm stages.

Antarctic subglacial lakes are studied for three main scientific reasons. First, they form an important component of the basal hydrological system which is known to affect the dynamics of the ice sheet. Second, they are amongst the most extreme viable habitats on Earth and third, if sediments exist on their floors, they may contain high-resolution records of ice sheet history. Here we present a new inventory of locations, dimensions and data sources for 379 subglacial lakes. Several major advances are responsible for the rise in the total number of lakes from the 145 known at the time of the last inventory in 2005. New radar datasets have been collected in previously unexplored regions of the ice sheet while digital data collection and processing techniques have allowed improvements to lake identification methods. Satellite measurements of ice surface elevation change caused by the movement of subglacial water have also been found to be widespread in Antarctica, often in places where radar data are absent. These advances have changed our appreciation of the Antarctic subglacial environment and have expanded our understanding of the behaviour of subglacial lakes.
