Antimicrobial resistance (AMR) is a major global threat to human and animal health. The use of antimicrobials in the livestock sector is considered to contribute to AMR. Therefore, a reduction in and prudent use of antimicrobials in livestock production systems have been advocated. This cross-sectional survey aimed to investigate the extent of imprudent antimicrobial use (AMU) and to determine whether the AMU practice was affected by either the farming system or species of farmed livestock in the largest island (Viti Levu) of Fiji. A total of 276 livestock enterprises were surveyed and antimicrobials were used on 309 occasions over 90 days. Overall, in 298 of 309 (96%) incidents, antimicrobials were used imprudently, comprising antibiotics, 160 of 170 (94%) and anthelmintics, 138 of 139 (99%). Prudent use of antibiotics was associated with commercial farming systems (X2 = 13, p = 0.001), but no association was observed with anthelmintic use (p > 0.05). Imprudent antibiotic use was associated with dairy (OR = 7.6, CI = 1.41, 41.57, p = 0.018) followed by layer and beef (p > 0.05) compared to broiler enterprises. Imprudent AMU was more common in the backyard and semi-commercial enterprises compared to commercial broiler enterprises. Policies promoting the prudent use of antimicrobials in Fiji should focus on smaller livestock production systems and enterprises.

Climate change is a great impact on Fiji’s ecosystem including animal (livestock and marine) and crop production from past decades and still possesses a large effect on their economy as well. These climatic events include flooding, rise in ambient temperature, rise in the sea level, droughts, tropical cyclones, and all others that bring large changes to the environmental system. These large changes adversely affect animal production and its economy in Fiji. Not only this, individuals that are linked to animal production are also affected through climatic conditions such as loss of income and livestock species that die out during cyclones and other aspects. Not only the terrestrial species but the marine organisms are also affected since climatic changes bring alterations to their feeding period and the mating time leading to a vast decrease in organisms’ health, quality, and population. Consequently, the Fijian government and other Pacific organizations have brought strategies like adaptation plans to implement in animal production sectors. These plans and methods will help farmers in stimulating their farming systems and adapting to climatic changes and hence, this will lead to increased productivity and economy. The aim and objective of this review are to define and elaborate the climatic change effects on livestock and marine production in Fiji and effective solutions adapted by Fiji and other Pacific governments to refrain from adverse climate conditions.

Tropical coastal zones have rich marine ecosystems; however, they have been enduring severe environmental hazards, particularly from anthropogenic activity and the effects of climate change. Seagrass ecosystem is one of the most productive yet undervalued marine ecosystems. The residents of Komave village, located on the mainland of Fiji have witnessed marked losses in seagrass cover over the last decade. Several of the village men in Komave are unemployed and rely on the coastal resources through fishing, livestock and agricultural farming for their socioeconomic livelihood. This research explores the impact of loss of seagrass cover on the villagers’ livelihood. This paper highlights the observations and experiences of the Komave villagers, in light of the interviews and discussions carried out at the community. A random sampling method was also used over a period of two years (March, 2015 – April, 2017) to monitor the seagrass habitat. The possible anthropogenic and natural factors contributing to the loss of Seagrass were gotten from the interviews and sampling physical environment. The nitrate content analysed from the random samples, reported values from 190 mg/L to a maximum value of 362.8 mg/L. It was also revealed that the areas where nitrate concentrations were greater than 300 mg/L, there was 0% sea grass cover in total, which confirms that if high levels of nitrates are present, sea grass cover is highly impacted. This paper concludes by providing recommendations for managing seagrass to enhance fisheries productivity in this tropical coastal community.

Ever since 1976, livestock farmers in Fiji have been intrigued about biogas digesters as an animal waste management measure, but the concept has never evolved into one that is sustainable. Renewed interest came in 1997 after a better Chinese Modified Dome (CMD) design was established, with this came government funding, however by 2002, some failure was also observed. This study set out to investigate the reasons why biogas digesters have never been established as a sustainable concept, its effectiveness as an animal waste management tool and what changes if any, can be made to try and influence the further development of the concept in Fiji. In order to achieve the objectives, which were simply obtaining the answers to the questions presented above, several different approaches had to be followed. This study was the first on biogas digesters in Fiji and it was unique in the sense that the major component dealt with the social aspects of farmers in relation to their biogas digesters. Basically the study was carried out in two parts - desktop studies and field studies. Desktop studies were done to better understand the situation while the field studies included semi-structured interviews with the farmers as well as the collection of biophysical data. Twelve outcomes are presented in chapter 7 of this paper. Two in particular are the improvement of construction and maintenance, which can only come about through training. The research questions are also answered in chapter 7, with recommendations put forward on possible directions to take in terms of trying to influence the development of the concept in Fiji
