Agricultural production in the Caribbean is being threatened by many factors such as decreasing availability of arable land, climate change effects such as increased incidences of flooding and drought, labour shortages, and competition from importers. However, one of the most important threats to agricultural production is the often under-recognised and under-reported area of farm theft (referred to as praedial larceny in the Caribbean). It involves the theft of agricultural produce (crops, livestock and fisheries) and farm equipment. One of the main reasons why this threat is so important is that theft of this type is very hard to prove. If indeed perpetrators are caught, and prosecuted successfully, the penalty is practically negligible. This paper examines the current status of farm theft in the Caribbean region, explores some of the main factors influencing farm theft, reviews some of the strategies attempted in the Caribbean and other places around the world and makes several suggestions to create a more secure food region. While the discussion calls on food producers to take several best practice actions to mitigate losses to praedial larceny, it emphasises that the primary responsibility is with government-led actions in the areas of modernised policies, updated laws and enhanced enforcement efforts.

The enhanced use of diesel fuel and the strict emission norms for the protection of environment have necessitated finding sustainable alternative and relatively green fuels for compression ignition engines. This paper presents a brief review on the current status of biodiesel production and its performance and emission characteristics as compression ignition engine fuel. This study is based on the reports on biodiesel fuels published in the current literature by different researchers. Biodiesel can be produced from crude vegetable oil, non-edible oil, waste frying oil, animal tallow and also from algae by a chemical process called transesterification. Biodiesel is also called methyl or ethyl ester of the corresponding feed stocks from which it has been produced. Biodiesel is completely miscible with diesel oil, thus allowing the use of blends of mineral diesel and biodiesel in any percentage. Presently, biodiesel is blended with mineral diesel and used commercially as fuel in many countries. Biodiesel fueled CI engines perform more or less in the same way as that fueled with the mineral diesel. Exhaust emissions are significantly improved due the use of biodiesel or blends of biodiesel and mineral diesel. The oxides of nitrogen are found to be greater in exhaust in case of biodiesel compared to mineral diesel. But the higher viscosity of biodiesel also enhances the lubricating property. Biodiesel being an oxygenated fuel improves combustion.

In recent years, there has been an increase in the number of diseases caused by bacterial, fungal, and viral infections. Infections affect plants at different stages of agricultural production. Depending on weather conditions and the phytosanitary condition of crops, the prevalence of diseases can reach 7080% of the total plant population, and the yield can decrease in some cases down to 8098%. Plants have innate cellular immunity, but specific phytopathogens have an ability to evade that immunity. This article examined phytopathogens of viral, fungal, and bacterial nature and explored the concepts of modern plant protection, methods of chemical, biological, and agrotechnical control, as well as modern methods used for identifying phytopathogens.

Introduction: The purpose of this research is to investigate the effect of agricultural production on economic output (agricultural production value) and the environment (carbon dioxide emissions) in Cambodia, Thailand, and Vietnam. These three countries, all located in the Mekong River region of Southeast Asia, are similar in terms of climate and agricultural potential, but the agricultural sector plays a different economic role in each of these three countries. While Thailand has had an export-oriented cash crop-based agricultural sector for decades, Cambodia and Vietnam continue to produce predominantly for domestic consumption. These differences have some implications for differences in economic productivity (output) and environmental effects (agricultural carbon emissions). Methods: This study investigates the effect of agricultural inputs, including the use of fertilisers, pesticide, agricultural land, irrigation, and agricultural employment, along with the rural population, GDP growth, exchange rates, and producer price indices, on agricultural output value and emissions using time series AR(1) analysis. Results: The results show different patterns for Thailand in comparison to Cambodia and Vietnam. Conclusion: This implies that no single agricultural policy can be used to promote agricultural growth in Mekong Delta countries.
