The control of invasive species in crops with low tolerance are seen as a public good. This makes it a collective responsibility led by government. This is done directly through public expenditure on control measures or indirectly through incentives to people whose actions may be a contributing factor to the problem. The risks associated with invasive species have been increasing especially with globalization but are changing in nature thus warranting novel strategies for their management.
At the inception of automated solar tracking in the 1970’s, geometric architectures with pair(/s) of solid-state photo-sensitive devices were constructed and used to detect the sun’s position. As an alternative in recent years, cameras have been used to capture and process live sky images to detect the sun’s position. When the sky is cloudy however, both approaches are prone to errors and sometimes require human intervention which tend to reduce the trackers’ economic viability [1].
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.
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.
Invasive alien species (IAS) are implicated in the extinction or decline of numerous native aquatic species worldwide. Their negative impacts occur through mechanisms including habitat alteration, competition, predation, hybridisation, and the spread of disease (Strayer et al. 2006). Small island ecosystems are most susceptible to the impacts of IAS. Once established, freshwater IAS are difficult to eradicate without negatively impacting native species.
A major challenge facing farmers in Portland, Jamaica is dry weather, especially during the optimal growing season from April through August. During this five-month period Portland suffered from severe dry spells during the years 2014, 2015, 2018 and 2020. A second challenge is the damage to crops and land as well as loss of livestock due to tropical storms or hurricanes and the associated flooding. Portland farmers have suffered losses due to an active hurricane season numerous times and most recently in the years 2004, 2005, 2012 and 2020.
