A field trial of the effect of improved piglet management on smallholder sow productivity in the Philippines

We conducted a randomised, controlled field trial during 1998/1999 to evaluate the hypothesis that improved piglet management would improve the reproductive performance of smallholder sows. Simple changes were introduced into the treatment herds including the construction of a heated piglet-separation pen, vitamin injections, creep feeding and early weaning. The control herds were unchanged. Data were collected from all sows in each enrolled herd over two farrowings. We enrolled 176 sows, including 170 (96 treatment and 74 control) sows that remained throughout the study period. Significant differences in the reproductive performance of treatment and control sows were recorded for interfarrowing interval (median 176 versus 220 days), average number liveborn over 2 litters (11 versus 12), and average preweaning mortality over 2 litters (0 versus 37%). Based on a discount rate of 17%, the benefit-cost ratio of the treatment was 11.1 and 12.1 over 3 and 5 years, respectively. (C) 2001 Elsevier Science B.V. All rights reserved.

Characterization of microsatellite loci in Anopheles flavirostris, the principal malaria vector in the Philippines

Microsatellites were isolated and characterized from Anopheles flavirostris, the principal malaria vector in the Philippines. Fifty of the 150 positive clones sequenced contained mostly dinucleotide microsatellites and only 16 had trinucleotide repeats. We designed primers from the unique sequences flanking 18 microsatellite loci. Of these, 11 loci produced successful amplification and revealed high levels of polymorphism; 86 alleles were detected with allele number ranging from 2 to 16 at each locus. The high allelic variability will make these microsatellite loci very useful for taxonomic and population genetic studies.

A framework of lessons learned from community-based marine reserves and its effectiveness in guiding a new coastal management initiative in the Philippines

Community-based coastal resource management has been widely applied within the Philippines. However, small-scale community-based reserves are often inefficient owing to management inadequacies arising because of a lack of local support or enforcement or poor design. Because there are many potential pitfalls during the establishment of even small community-based reserves, it is important for coastal managers, communities, and facilitating institutions to have access to a summary of the key factors for success. Reviewing relevant literature, we present a framework of lessons learned during the establishment of protected areas, mainly in the Philippines. The framework contains summary guidance on the importance of (1) an island location, (2) small community population size, (3) minimal effect of land-based development, (4) application of a bottom-up approach, (5) an external facilitating institution, (6) acquisition of title, (7) use of a scientific information database, (8) stakeholder involvement, (9) the establishment of legislation, (10) community empowerment, (11) alternative livelihood schemes, (12) surveillance, (13) tangible management results, (14) continued involvement of external groups after reserve establishment, and (15) small-scale project expansion. These framework components guided the establishment of a community-based protected area at Danjugan Island, Negros Occidental, Philippines. This case study showed that the framework was a useful guide that led to establishing and implementing a community-based marine reserve. Evaluation of the reserve using standard criteria developed for the Philippines shows that the Danjugan Island protected area can be considered successful and sustainable. At Danjugan Island, all of the lessons synthesized in the framework were important and should be considered elsewhere, even for relatively small projects. As shown in previous projects in the Philippines, local involvement and stewardship of the protected area appeared particularly important for its successful implementation. The involvement of external organizations also seemed to have a key role in the success of the Danjugan Island project by guiding local decision-makers in the sociobiological principles of establishing protected areas. However, the relative importance of each component of the framework will vary between coastal management initiatives both within the Philippines and across the wider Asian region.

The Politics of Decentralizing National Parks Management in the Philippines

International donors and state bureaucrats in the developing world have promoted decentralization reform as the primary means to achieve equitable, efficient and sustainable natural resource management. Relatively few studies, however, consider the power interests at stake. Why do state agencies decentralize power, what political patterns unfold, and how do outcomes affect the responses of resource users? This paper explores decentralization reform by investigating the political processes behind the Philippine state's decisions to transfer authority over national parks management to local government units. Drawing on a case of devolved management at Puerto Princesa Subterranean River National Park, Palawan Island, we examine how political motives situated at different institutional scales affect the broader process of decentralization, the structure of management institutions, and overall livelihood security. We demonstrate how power struggles between the Philippine state and City Government of Palawan over the right to manage the national park have impacted the livelihood support offered by community-based conservation. We conclude that decentralization may offer empowering resu

Workplace familism and psychological contract breach in the Philippines

The present study addresses the call for theory-based investigations on workplace familism. It contributes to the literature by proposing and testing the moderating role of workplace familism between psychological contract breach and civic virtue behaviour. We surveyed 267 full-time employees and found main effects of both types of workplace familism (i.e. workplace organisational and workplace supervisor familism) and breach of relational obligations on civic virtue behaviour. Workplace supervisor familism also moderated the relationship between breach and civic virtue behaviour, with the negative relationship between breach and civic virtue behaviour stronger when workplace supervisor familism was high. This suggests that employees with a high level of workplace supervisor familism may feel a sense of betrayal and, therefore, respond more negatively to contract breach. Implications for practice and directions for future research are discussed.
