Piano grass (Themeda arguens), reputed to have been introduced to Jamaica as packing material in an imported piano1 . There are about 27 varieties of this highly invasive grass/weed worldwide[1] and in Jamaica the species previously identified as Themeda arguens is of concern as it has progressively taken over lawns, pastures and roadsides [1]. The grass is of particular concern to livestock farmers due to its highly invasive and aggressive nature and the concomitant negative effect on livestock productivity, especially during its annual seeding period (November/December – April) [2], when the palatability of the grass diminishes significantly and the seed awns can cause severe damage to the mouth when consumed, and feet of livestock [2], sometimes requiring veterinary intervention.
The malaria epidemic was responsible for about 241 million infectious cases and 627,000 deaths worldwide in 2020.[1] This infectious disease, transmitted by the female Anopheles mosquito, is caused by parasites of the genus Plasmodium namely P. falciparum, P. vivax, P. malariae, P. knowlesi, P. ovale curtisi and P. ovale wallikeri.[2,3] Also, malaria is found predominantly in the highlands of Africa which accounts for more than 90% of infections worldwide. While there has been some success in the treatment of malaria, its eradication has been negatively impacted by insecticide and drug resistance. With emergence of thiosemicarbazone as antimalarial agents, the combination of pyridine and amide or thioamide moieties into one scaffold makes for an interesting target.[4]
The worldwide ginger market was valued at US$6.82 billion in 2020, with India, Nigeria and China being the top global producers (Global Ginger Market Report, 2021). Jamaican ginger once held pride of place in the global market, with its widely accepted superior quality, uniqueness of flavor and high oil content. However, since the initial outbreak of the ginger rhizome rot disease in 1995, production has drastically plummeted to insignificant levels and the industry has not yet recovered. In this regard, a number of intervention strategies have been implemented by the Government of Jamaica over the years, including the Eastern Jamaica Agricultural Support Project of 1993 under RADA, the Ginger Agricultural Science, Technology and Innovation Working Group initiative supported by the CTA ACP-EU under the National Commission and Science and Technology in 2005, the Ginger Resuscitation and Expansion Programme of 2011 led by the Export Division of the Ministry of Agriculture, the Ginger Value Chain Study supported by the FAO, the Ginger Varietal Study funded through the Jamaica Business Development Fund in 2018 and the ongoing Ginger Value Chain and Certification Programme supported by the FAO, with propagation and production of disease-free planting materials. These programmes, amounting to investments of millions of dollars, through partnerships with the key private, governmental and international stakeholders, have been met with varying degrees of success.
Numerous organic chemicals, either directly manufactured or formed as byproducts of other processes, are released into the environment. Once there, many cause adverse effects on environmental and human systems. Of particular concern are long-lasting impacts from those organic pollutants that remain in the environment for long periods of time. The development of appropriate management strategies to address this problem requires knowledge of the environmental distributions of these pollutants.
