Charles Darwin Foundation for the Galapagos Islands.
The truth is that limits must be placed on growth in Galapagos, in order to achieve sustainability. I discuss the recent and projected growth in tourism to the islands and possible methods of achieving sustainability in the tourism industry, to make it compatible with the conservation of the islands. A move towards greater income per visitor, and tighter regulation of tourism linked to responsible operations and behaviour, are essential if sustainability is to be achieved.

During the first week of April 1986, before the overwhelming presence of goats, we sampled terrestrial macro- invertebrates on Alcedo Volcano along an altitudinal transect from the seashore to the top. Vegetation composition and structure at all sampling sites were described and photographs were taken. In 1996, when the Alcedo feral goat population had exploded to an estimated 50,000 to 100,000 and before large scale goat control began, the same transect was resampled and redocumented. In this contribution, site descriptions are summarized, compared between 1986 and 1996 and illustrated with a series of photographs.

The fermented product from small rock oyster (Sacosstrea sp.) locally known, 'Sisi' is an essential source of livelihood in Zumarraga, Samar. Key informant interviews, ocular observation and focus group discussion (FGD) were conducted to find out the traditional practices used in producing 'Sisi'. Salient findings showed that non-standardized processing of Sisi was practiced, thus limiting the revenues derived from this marginalized industry. Furthermore, 'Sisi' has high ash content with high microbial count which indicates that there are some colonies that grow in the mixture. Hence, there is a need to standardize the methods applied in producing fermented small rock oyster...

A total of 37 beneficiaries under the Philippine National Aquasilviculture Program (PNAP) was interviewed using the structured survey questionnaire of Socioeconomic Monitoring Guidelines for Coastal Managers in Southeast Asia (SocMon SEA). Most of the members of the households are young and in-school. Household heads’ primary occupation is fishing, a shift from mussel farming- the town’s major industry in the past decades. Perceived threat by the beneficiaries is related to the environment specifically typhoon and the problems on waste disposal. It also identified law enforcement as weak leading to dwindling fish catch, mass mortality of mussel, red tide and other problems...
This research develops four case studies on small-scale fisheries in Central America located within indigenous territories. The ngöbe Bugle Conte Burica Territory in the south of Costa Rica, the Garífuna territory in nueva Armenia Honduras, the Rama territory in Nicaragua and the ngöbe Bugle territory in Bocas del Toro, Panamá. This is one of the first studies focusing on indigenous territories, artisanal fisheries and SSF guidelines. The cases are a first approach to discussing and analyzing relevant social and human rights issues related to conservation of marine resources and fisheries management in these territories. The cases discussed between other issues...
A recent workshop at New Delhi discussed capacity building for the implementation of the Voluntary Guidelines for Securing Sustainable Small-scale Fisheries (SSF Guidelines).
The poster explains human activties carried out in critical fish habitats such as breeding and nursery zones.

Uganda is rich in aquatic resources. Up to 17 % of the country's surface area is covered by Aquatic systems comprising five major lakes; Victoria, Albert, Kyoga, Edward, George, about 160 minor lakes, an extensive river and stream system, dams and ponds. These aquatic systems are associated with extensive swamps
Natural populations of fish species in Lake Victoria Region (LVR) have under gone dramatic changes including severe reduction in sizes, division of original stocks into disjunct subunits, and segregation into several isolated population units either within a single water body or even worse into separate waters. In addition, these changes have been either preceded or precipitated by introductions of non-indigenous species that out competed the native forms and in case of closely related species genetically swamped them through hybridisation. The latter is especially the case in Nabugabo lakes. Such events lead to fragmentation of populations, which results in reduction in...

The wide-spread impact of exotic fishes especially Oreochromis niloticus and Lates niloticus together with over fishing in the Victoria and Kyoga lake basins during the 1950s and 1960s, caused endemic species such as the previously most important Oreochromis esculentus to become virtually extinct in the two lakes by the 1970s. Based on reports of presence of this native species in some satellite lakes within the two lake basins, a set of satellite lakes in the Victoria basin (Nabugabo lakes: Kayanja and Kayugi), were sampled between 1997-2002 with an objective of assessing their value as conservation sites for O. esculentus. Other...

Fish species diversity in Lake Nabugabo, Uganda, has declined following establishment of the introduced fish species in the lake. Most of the native fish species have disappeared and the lake is now dominated by the introduced Nile perch, Lates niloticus and the Nile tilapia Oreochromis niloticus. The dominant native fish species include Synodontis afrofischeri, Schilbe intermedius, Rastrineobola argentea and Brycinussadleri. Some of the native fish species that have disappeared from Lake Nabugabo were reported to occur in lakes Kayugi and Kayanja, which are adjacent to Lake Nabugabo but separated from it by extensive papyrus swamps. The Nabugabo lakes are satellite...

Nakivubo swamp (papyrus wetland) is located in the south east of the city of Kampala, Uganda. This swamp has been receiving waste water from Nakivubo channel for more than two decades. This investigation was aimed at monitoring the level of pollutants (nutrients and faecal coliforms) as the waste water filtrates through the swamp and the flow patterns of waste water through the swamp.
From this preliminary investigation it was found out that the waste water is not evenly distributed over the swamp. Also high levels of pollutants seem to filtrate through the swamp and enter Inner Murchison Bay - Lake Victoria....
