ABSTRACT

Management of deep-sea fisheries in areas beyond national jurisdiction by Regional Fisheries Management Organizations/Arrangements (RFMO/As) requires identification of areas with Vulnerable Marine Ecosystems (VMEs). Currently, fisheries data, including trawl and longline bycatch data, are used by many RFMO/As to inform the identification of VMEs. However, the collection of such data creates impacts and there is a need to collect non-invasive data for VME identification and monitoring purposes. Imagery data from scientific surveys satisfies this requirement, but there currently is no established framework for identifying VMEs from images. Thus, the goal of this study was to bring together a large international team to determine current VME assessment protocols and establish preliminary global consensus guidelines for identifying VMEs from images. An initial assessment showed a lack of consistency among RFMO/A regions regarding what is considered a VME indicator taxon, and hence variability in how VMEs might be defined. In certain cases, experts agreed that a VME could be identified from a single image, most often in areas of scleractinian reefs, dense octocoral gardens, multiple VME species' co-occurrence, and chemosynthetic ecosystems. A decision flow chart is presented that gives practical interpretation of the FAO criteria for single images. To further evaluate steps of the flow chart related to density, data were compiled to assess whether scientists perceived similar density thresholds across regions. The range of observed densities and the density values considered to be VMEs varied considerably by taxon, but in many cases, there was a statistical difference in what experts considered to be a VME compared to images not considered a VME. Further work is required to develop an areal extent index, to include a measure of confidence, and to increase our understanding of what levels of density and diversity correspond to key ecosystem functions for VME indicator taxa. Based on our results, the following recommendations are made: 1. There is a need to establish a global consensus on which taxa are VME indicators. 2. RFMO/As should consider adopting guidelines that use imagery surveys as an alternative (or complement) to using bycatch and trawl surveys for designating VMEs. 3. Imagery surveys should also be included in Impact Assessments. And 4. All industries that impact the seafloor, not just fisheries, should use imagery surveys to detect and identify VMEs.

ABSTRACT

This study assessed changes in contraceptive use and fertility between 2009 and 2013 in the Velondriake locally managed marine area of southwest Madagascar where marine conservation organization Blue Ventures began implementing an integrated health-environment program in 2007. The proportion of sexually active women aged 15 to 49 years using hormonal contraception and/or condoms during last intercourse increased more than twofold from 25 percent in 2009 to 59 percent in 2013. The number of births in the last 12 months per 1,000 women of reproductive age declined by 20 percent over the same period from 178 in 2009 to 143 in 2013. This program increased access to family planning for previously under-served communities, leading to uptake of modern contraceptives with an associated decline in fertility. These results suggest that this program has enabled couples to avoid unintended pregnancies, thereby bolstering local marine conservation initiatives.

ABSTRACT

OBJECTIVES: As part of a broader investigation into maternal and child health, this study aimed to explore barriers to preventing unintended pregnancies and sexually transmitted infections (STIs) for women in southeast Madagascar, in order to inform the development of interventions by a local non-governmental organisation. METHODS: A year-long mixed methods study was conducted. Qualitative information was obtained from 246 participants through focus groups, single-event and serial qualitative interviews. Quantitative data was collected through a closed-ended questionnaire with a sample of 373 women of reproductive age. Data was analysed using pre-determined and emerging themes. RESULTS: Family planning and sexual health services are not well integrated into other health services, nor routinely offered. Barriers to contraceptive use include actual or perceived side effects of hormonal methods, inaccurate information from health providers, and lack of support from partners or family members. STI prevalence is high, concurrent sexual relationships are common, and condom use is limited. CONCLUSIONS: Women's ability to prevent unintended pregnancies and STIs could be improved through measures aiming to dispel misconceptions about eligibility for and perceived risks of hormonal contraceptives, increase support for family planning among partners and families, and reframe the socio-cultural meaning of condom use in sexual relationships.

ABSTRACT

Contextualising maternal health in countries with high maternal mortality is vital for designing and implementing effective health interventions. A research project was therefore conducted to explore practices, beliefs and traditions around pregnancy, delivery and postpartum in southeast Madagascar. Interviews and focus groups were conducted with 256 pregnant women, mothers of young children, community members and stakeholders; transcripts were analysed to identify and explore predetermined and emerging themes. A questionnaire was also conducted with 373 women of reproductive age from randomly selected households. Data was analysed using STATA. Results confirmed high local rates of maternal mortality and morbidity and revealed a range of traditional health care practices and beliefs impacting on women's health seeking behaviours. The following socio-cultural barriers to health were identified: 1) lack of knowledge, 2) risky practices, 3) delays seeking biomedical care, and 4) family and community expectations. Recommendations include educational outreach and behaviour change communications targeted for women, their partners and family, increased engagement with traditional midwives and healers, and capacity building of formal health service providers.
