No results found.There is a distinct population of blue whales, Balaenoptera musculus, in the northern Indian Ocean. The taxonomic status of these animals has long been uncertain, with debate over whether this population represents a distinct subspecies, and if so which me should apply. They have most frequently been assigned to B. musculus brevicauda, but are currently considered to be B. m. indica. The movements of these blue whales within the northern Indian Ocean are poorly understood. This paper reviews cat ches (n = 1,288), sightings (n = 448, with a minimum of 783 animals), strandings (n = 64) and acoustic detections (n = 6 locations); uses ocean colour data to estimate seasolity of primary productivity in different areas of the northern Indian Ocean; and develops a migration hypothesis. It is suggested that most of these whales feed in the Arabian Sea off the coasts of Somalia and the Arabian peninsula during the period of intense upwelling associated with the southwest monsoon (from about May t o October). At the same time some blue whales also feed in the area of upwelling off the southwest coast of India and west coast of Sri Lanka. When the southwest monsoon dies down in about October–November these upwellings cease. The blue whales then disperse more widely to eke out the leaner months of the northeast monsoon (during about December to March) in other localised areas with seasolly high productivity. These include the east coast of Sri Lanka, the waters west of the Maldives, the vic inity of the Indus Canyon (at least historically), and some parts of the southern Indian Ocean. The data are consistent with the hypothesis that at least some of the blue whales that feed off the east coast of Sri Lanka in the northeast monsoon also feed in the Arabian Sea during the southwest monsoon. These whales appear to migrate eastwards past the north of Maldives and south of Sri Lanka in about December–January, returning westwards in about April–May. -

Book (stand-alone)Proceedings推广生态农业 实现可持续发展目标 — 联合国粮食及农业组织第二届生态农业国际研讨会纪实 2021
Also available in:
2018年4月,联合国粮农组织(FAO)召开了第二届生态农业国际研讨会:“推广生态农业 实现可持续发展目标”。本届研讨会达成了部分协议并作出相关承诺,为推广生态农业、实现可持续发展目标奠定了基础。会议讨论并列举了推广生态农业为当地带来的主要好处、在全球层面推广生态农业的机遇以及将生态农业纳入其全球项目的具体路径,并发起了“生态农业推广举措”。该“举措”被视为推动并实现《2030年可持续发展议程》(特别是可持续发展目标2)的未来方向和战略方法。 -
