Management of coconut ( Cocos nucifera ) lethal yellowing disease (CLYD), which has killed about eight million coconut trees in Mozambique, has proved challenging. The objective of this study was to investigate the impact of farming practices and related history, on the CLYD incidence in Mozambique. The methodology included a socioeconomic questionnaire to the households and direct observations on the palm farms. The collected data were analysed using logistic regression. Five out of 11 explanatory variables tested, namely farm age, availability of other palm species on the coconut farm, type of coconut varieties grown, root cut practices, and intercropping had a significant (P< 0.05) effect on CLYD incidence. Coconut farms <10 years had higher odds of higher disease incidence compared to the farms between 10 to 40 years old. The presence of other palm species in the coconut farms had two times higher odds of having higher disease incidence levels compared to farms without other palm species. Tall coconut varieties were likely to be more tolerant to CLYD compared to dwarf varieties. Coconut farms with some kind of intercropping had two times higher odds of having higher disease incidence levels compared to pure stands. The practice of cutting coconut roots had three times higher odds of having high disease incidence levels compared to non-practicing farms. Farm age, availability of other palm species on the coconut farm, type of coconut varieties grown, root cut practices and intercropping need to be considered for integrated CLYD management.

Background: In Nigeria, the relationship between spousal violence and pregnancy termination had not been adequately explored. Objectives: To assess the prevalence of spousal violence, and examine the relationship between spousal violence and pregnancy termination. Methods: Data on spousal violence among ever married women was extracted from the 2013 Nigeria Demographic and Health Survey. The outcome variable is pregnancy termination. The explanatory variables were the type of spousal violence experienced by the women in the last 12 months preceding the survey. Descriptive statistical analysis and binary logistic regression were applied using stata version 12. Results: Results show that 13.8% of women had ever terminated pregnancy; 19.9% had ever experienced at least one type of spousal violence; and women who had ever terminated pregnancy had higher prevalence of all types of spousal violence. Women who had ever experienced spousal physical violence were 9% more likely to experience pregnancy termination (OR=1.09; CI: 1.03-2.86); and women who had ever experienced spousal emotional violence were 33% more likely to experience pregnancy termination (OR=1.33; CI: 0.97-1.95). Conclusions: Spousal violence is significantly related to pregnancy termination. Improving women’s sexual and reproductive health in the country requires fresh initiatives that address spousal violence to further reduce women’s exposure to pregnancy termination.
