Fishing Practices

We are among the scientists who have documented the environmental and ecological changes to the Upper Gulf of California following the reduction in the Colorado River’s flow. We object to any suggestion that our research supports Manjarrez-Bringas et al.’s conclusion that the decline in the Colorado River’s flow is the reason for the decline in the population of the endangered vaquita porpoise (Phocoena sinus). Manjarrez-Bringas et al.’s conclusions are incongruent with their own data, their logic is untenable, their analyses fail to consider current illegal fishing practices, and their recommendations are unjustified and misdirected. Vaquita face extinction because of bycatch, not because of the lack of river flow.

Despite the rapidly growing expenditure on digital advertising, the effectiveness of the functioning of the digital advertising ecosystem is becoming less and less visible. This is related to the fact that only a small part of the expenditure incurred by organizations on various forms of digital advertising brings the expected results. For several years now, a phenomenon that stifles the effectiveness of the digital advertising ecosystem and deteriorates the ROI (return on investment) of advertisers has been the widespread practice of blocking advertising, known as ad-blocking. In this context, the aim of this article is to analyze the scale of the phenomenon of ad-blocking and its causes in terms of its impact on the effectiveness of the functioning of the digital advertising ecosystem and its sustainable development, which is extremely important from the point of view of the development of electronic commerce. In order to carry out this study, a literature analysis was conducted on the genesis of this phenomenon, its scale, causes, and economic effects. After this stage of research, in order to obtain primary data, a questionnaire survey was conducted on a group of individual Internet users. The results of the research indicated three main reasons for the development of ad-blocking. These are: excessive number of advertisements, their excessive invasiveness, and the mismatch between the advertisements displayed to the user and the user’s interests. In the context of these results and of the continued sustainable functioning of the digital advertising ecosystem, it is essential that the advertising industry be able to offer users alternatives to ad-blocking that they consider valuable from their own point of view and that take the users’ expectations into account.

Africa's efforts to achieve sustainable development have been hindered by factors such as skills development and enhancing market access in support of sustainable transformation and infrastructure that promote sustainable development and connectivity in Africa. Continental connectivity and logistical problems are the result of peculiar socio-economic conditions in the region such as geology, poor economic governance and conflict. These issues have direct implications for the implementation of infrastructure projects and the type of public policies needed to foster strategic connectivity. Moreover, the major constraints on infrastructure are not technical but managerial, political, ‘cultural’ and due to a lack of specialised resources. Africa needs to find its own solutions to local capacity and development problems with greater involvement of local private sector partners wherever feasible. A political economy perspective is critical to understand the dynamics around infrastructure deficits as well as associated investments and development.

Tais políticas deverão estar dirigidas a objetivos ambientais definidos em função do grau de qualidade ambiental urbana presente e da eqüidade da sua distribuição espacial, visando a uma situação futura desejada. Public policies and urban sustainable development Abstract Considering that urban development is directly related to the spreading of environmental impacts caused by human settlements within city limits and the existence of directives in the Brazilian Agenda 21 regarding the promotion of urban sustainability, as well as the content of the City Statute regarding urban policies towards sustainable cities and urban planing, this study presents possibilities of implementing directives and legal measures for urban management by means of local public policies concerning transportation, habitation and land use. Such policies should be directed towards environmental objectives, defined with regard to the present urban environmental quality and spatial distribution, aiming at a desired future condition.

AbstractThe human footprint index is an extensively used tool for interpreting the accelerating pressure of humanity on Earth. Up to now, the process of creating the human footprint index has required significant data and modeling, and updated versions of the index often lag the present day by many years. Here we introduce a near-present, global-scale machine learning-based human footprint index (ml-HFI) which is capable of routine update using satellite imagery alone. We present the most up-to-date map of the human footprint index, and document changes in human pressure during the past 20 years (2000 to 2019). Moreover, we demonstrate its utility as a monitoring tool for the United Nations Sustainable Development Goal 15 (SDG15), “Life on Land”, which aims to foster sustainable development while conserving biodiversity. We identify countries that are making progress toward SDG15 while also experiencing increases in their ml-HFI. We briefly examine a subset of these in the context of conservation policies that may or may not enable continued progress toward SDG15. This has immediate policy relevance, since the majority of countries globally are not on track to achieve Goal 15 by the declared deadline of 2030. Moving forward, the ml-HFI may be used for ongoing monitoring and evaluation support toward the twin goals of fostering a thriving society and global Earth system.

Kenyan Coast

In 2011, several non-governmental and government agencies established the Kenya Marine Mammal Network (KMMN) to provide a platform for the consistent collection of data on marine mammals along the Kenyan coast, identify areas of importance and engage marine users and the general public in marine mammal conservation. Prior to the KMMN, relatively little was known about marine mammals in Kenya, limiting conservation strategies. The KMMN collects data nationwide through dedicated surveys, opportunistic sightings and participative citizen science, currently involving more than 100 contributors. This paper reviews data on sightings and strandings for small cetaceans in Kenya collated by the KMMN. From 2011 to 2019, 792 records of 11 species of small cetaceans were documented. The most frequently reported inshore species were the Indo-Pacific bottlenose dolphin and Indian Ocean humpback dolphin. Offshore species, included killer whales, short-finned pilot whale and long-snouted spinner dolphin. Indo-Pacific bottlenose dolphins, long-snouted spinner dolphins, striped dolphins and Risso’s dolphins were recorded through stranding reports. The efforts of the KMMN were disseminated through international meetings (International Whaling Commission, World Marine Mammal Conference), national status reports, outreach and social media. Data has also supported the identification of three IUCN Important Marine Mammal Areas and one Area of Interest in Kenya. Further research is needed to improve estimates of cetacean abundance and distribution, particularly in unstudied coastal areas, and to assess the extent of anthropogenic threats associated with fisheries, coastal and port development, seismic exercises and unregulated tourism. The expansion of the network should benefit from the participation of remote coastal fishing communities, government research agencies, tourism and seismic operations, among others. The KMMN demonstrated the value of dedicated and citizen science data to enhance marine mammal conservation strategies to boost awareness and eco-tourism and to bring the public and science closer together, promoting research and effective conservation efforts.
