Essential oils serve as a natural alternative to chemical or synthetic antimicrobials and antioxidants to fight against food borne pathogens or spoilage organisms, inhibiting lipid peroxidation and extending the shelf life of fish and other seafood. This study examines the antibacterial properties of essential oils from leaves of Ocimum gratissimum L. from two localities of the North West and South West of Cameroon on some pathogenic spoilage gram negative and positive bacteria isolated from mackerel, and their antimicrobial and antioxidant effectiveness on the fish quality during preservation for one month at -18oC. The plant materials were harvested from Bambili, the North West Region of Cameroon and from Mbonge, the South West Region of Cameroon and the essential oils extracted by hydro-distillation using Clevenger-type apparatus. Escherichia coli, Salmonella typhi and Staphylococcus aereus were isolated from mackerel by culture techniques and their susceptibility to the essential oils determined by well diffusion method. Psychrophilic bacteria and Enterobacteraceae counts were used to evaluate the microbiological quality of the fish during storage. Total volatile basic nitrogen and thiobarbituric acid reactive substance assays were used as indices to assess the biochemical quality of the fish during storage. Antibacterial susceptibility test showed that essential oils of O. gratissimum from the North West and South West Regions were active on all the tested microorganisms with different degree.The inhibitory diameters for essential oil from the South West Region were 28.0 mm, 27.2 mm and 26.0 mm while that for essential oil from the Bambili were 24.1 mm, 20.4mm and 21.9 mm for Staphylococcus aereus, Escherichia coli and Salmonella typhi respectively. At the end of storage periods, the values of Psychrotrophs plate counts, total volatile base nitrogen and thiobarbituric acid reactive substances for fish samples treated with essential oil from the Mbonge were 2.71log10cfu/g, 12.88 mgN/100g and 0.88 mgMDA/Kg, while that treated with North West essential oil were 3.00 log10cfu/g, 16.24 mgN/100g and 1.26 mgMDA/Kg respectively. From the obtained results, essential oil of O. gratissimum from the Mbonge was the most effective in preserving Atlantic mackerel.

In the North-West region, spring barley is the main grain fodder crop. The variety is an effective and most affordable means of increasing the harvest and quality of the grain. The studying selection material for breeding ensures success in the creation of new varieties. European varieties are characterized by resistance to powdery mildew, which is a limiting factor of breeding in the North-West region. This work aimed to find new sources of agrobiological valuable traits. In 2016-2018, which differed in weather conditions, 32 varieties of spring barley were studied on the field of the Pushkin Laboratory of VIR. As a result of studying a set of samples of the Western European ecological group, according to the main agrobiological valuable traits sources for breeding in the North-West region were identified: early maturing, semi-dwarf, large-grain variety – “Brucefield” (к-31555, parallelum, Germany); semi-dwarf, large-grain variety – “Brennus” (к-31331, nutans, France); middle-maturity, high-yielding, large-grain, semi-dwarf, resistant to lodging, with an adaptation coefficient more than 1 – “Niagara” (к-31334, nutans, France), “Tocada” (к-31341, deficiens, Germany), “Juhata” (к-31346, nutans, Germany), “KWS Alciana” (к-31348, nutans, Germany).

This work seeks to evaluate, the links between the physical effects of enclavement and the development of the rural sector in Menchum Valley of the North West Region of Cameroon. It postulates the deterrent effect of physical enclavement on the livelihood of the people. Data collected from the field between 2017 and 2019 using the survey method (quantitative and qualitative methods 96 questionnaires administered, 6 focus groups, and 530 sample size), was treated using SPSS and Excel. The findings brought out 3 basic issues which are: enclavement naturally affects the inputs and output in the area, it discourages peasants’ agricultural sales as the main source of livelihood and inaccessibility induced by physical enclavement[1] principally in the rainy season makes movement in and out of the area difficult and renders the people poor due to the fact that there are few buyers and many sellers thus supply greater than demand and prices are low. A total of 80% of the respondents think that the Menchum Falls (nature’s gift to the Valley) can be a very strong force in disenclaving Menchum Valley and improving on their quality of live of the people if a dam to harness electricity is constructed on it.

This article argues that the number of unprosecuted human traffickers is growing in Cameroon. This article aims to examine Cameroonian government officials, prosecutors and judiciary attitudes to human trafficking laws, which endanger Cameroonians. This article is an empirical study of victims of human trafficking. It takes an objective look at Cameroon's anti-trafficking law that criminalises the trafficking of adults and children. It is evident that societal discrimination towards the North West region, lack of opportunities for free education or to a trade post-primary school and the lack of enforcement of the anti-trafficking law are making combating human trafficking an arduous task.

ABSTRACTIndonesia is the world's largest producer of crude palm oil (CPO). Even so, the trend of international trade in Indonesian CPO products has decreased in the last 10 years with a value of -10.19%. The decline in world demand for CPO can be dealt with by utilizing CPO as a biofuel for domestic use, like biodiesel. The purpose of this study is to determine the competitiveness of Indonesian CPO in global trade and determine the parameters of the quality requirements of CPO and biodiesel. The competitiveness analysis method uses the Revealed Comparative Advantage (RCA) method, while the analysis of the potential quality of CPO as a biofuel is carried out by analyzing the Indonesian National Standard (SNI). CPO trade in the global market is controlled by Indonesia with a market share of 50% and Malaysia 25.6%, with the declining trade trend in the last 10 years relatively (2010-2019) of -6.91%. The level of competitiveness of Indonesian CPO products in 2019 is very strong, but on average in the last 10 years, the level of competitiveness of Indonesian CPO is no better than that of Malaysia. Indonesia has SNI 01-2901-2006 and SNI 7182: 2015 as a determinant of the quality of CPO and biodiesel products developed in Indonesia so that the CPO and biodiesel produced fullfil sacurity and safety aspects when used by consumers.Keywords: crude palm oil (CPO), competitivenessv, quality, Indonesian National Standard (SNI) ABSTRAKIndonesia merupakan negara produsen minyak kelapa sawit mentah/ Crude Palm Oil (CPO) terbesar di dunia. Meskipun demikian, tren perdagangan internasional produk CPO Indonesia mengalami penurunan dalam sepuluh tahun terakhir dengan nilai -10,19%. Penurunan permintaan dunia terhadap CPO, dapat disiasati dengan memanfaatkan CPO sebagai bahan bakar nabati untuk keperluan dalam negeri sebagai biodiesel. Tujuan penelitian ini adalah mengetahui daya saing CPO Indonesia dalam perdagangan global dan mengetahui parameter persyaratan mutu CPO dan biodiesel. Metode analisis daya saing menggunakan metode Revealed Comparative Advantage (RCA), sedangkan analisis potensi kualitas CPO sebagai biofuel dilakukan dengan menganalisis Standar Nasional Indoensia (SNI). Perdagangan CPO dalam pasar global dikuasai oleh Indonesia dengan pangsa pasar 50% dan Malaysia 25,6%, dengan tren perdagangan relatif menurun dalam 10 tahun terakhir (2010-2019) sebesar -6,91%. Tingkat daya saing produk CPO Indonesia pada tahun 2019 sangat kuat, namun secara rata-rata dalam 10 tahun terakhir, tingkat daya saing CPO Indonesia tidak lebih baik dari Malaysia. Indonesia memiliki SNI 01-2901-2006 dan SNI 7182:2015 sebagai penentu kualitas produk CPO dan biodiesel yang dikembangkan di Indonesia, sehingga CPO dan biodiesel yang dihasilkan memenuhi aspek keamanan dan keselamatan ketika digunakan oleh konsumen.Kata kunci: crude palm oil (CPO), daya saing, kualitas, Standar Nasional Indonesia (SNI)

The purpose of this study is to examine the effect of the rural household’s head and household characteristics on credit accessibility. This study also seeks to investigate how credit constraint affects rural household welfare in the Mezam division of the North-West region of Cameroon. Using data from a household survey questionnaire, we found that 36.88% of the households were credit-constrained, while 63.13% were unconstrained. A probit regression model was used to examine the determinants of households’ credit access, while an endogenous switching regression model was used to analyze the impact of credit constraint on household welfare. The results from the probit regression model indicate the importance of the farmer’s or trader’s organization membership, occupation, and savings to the household’s likelihood of being credit-constrained. On the other hand, a prediction from the endogenous switching regression model confirms that households with access to credit have a better standard of welfare than a constrained household. From the results, it is necessary for the government to subsidize microfinance institutions, so that they can take on the risk of offering credit to rural households.
