Opis:
Climate change has brought about irregularity in pattern and intensity of climatic variables such as rainfall and temperature that are important in crop production; making planning in agriculture difficult. The importance of cassava in the diet of Nigerian and its industrial use necessitate the need to examine the effects of climatic variability on cassava production. Secondary data obtained from Nigerian Meteorological Agency (NIMET) were used for the study. Analysis of Variance and Error Correction model were utilized.  The study showed that the rainforest zone had the highest averages of annual rainfall (1709mm) and relative humidity (82.1%) while the Sahel savannah had the highest mean annual temperature (35.3oC). The variability in annual rainfall and relative humidity was low in the rainforest zone. The study showed that the rainforest zone had the least dispersion of average annual relative humidity (2.06%) while the guinea savannah had highest dispersion (4.68%). The average cassava output from the agro-ecological zones was 49,118,871MT per year. Rainforest and guinea savannah accounted for 56.3% and 41.9% of total cassava output respectively. There were significant variations in the climatic variables (rainfall and temperature) among the agro-ecological zones but not significant among the years (p>0.05).  The annual rainfall and solar radiation were the factors that influenced cassava output in all the agro-ecological zones. The need for affordable irrigation by cassava farmers and the adoption of Climate-Smart Agriculture are recommended to boost cassava production in Sudan savannah and Sahel savannah.

Opis:
Biotechnology has potential to enhance the production of agricultural and industrial products for achieving food security and economic development. In agriculture, biotechnology enhances the production of high yielding and disease resistance crops necessary for achieving food security and industrial development. This paper examines the constraints in the application of biotechnology research to the production of cassava in Nigeria. The study utilized primary data collected through questionnaire administration and interview from three research institutions working on cassava biotechnology in Nigeria. Findings showed that weak infrastructural facilities, poor funding, inadequate competent personnel and absence of appropriate legislation are the constraints in the application of biotechnology to cassava production in Nigeria. In addition, one out of the three research institutions has adequate and regular electricity supply through its own captive power plant while the remaining two research institutions relied more on electricity from the national grid. Inadequate funding and shortage of competent personnel were peculiar challenge confronting all the research institutions covered by the study. The study recommends improvement in electricity supply, production of more biotechnology scientists and adequate funding to enhance biotechnology research in Nigeria.

Opis:
The majority of the population in Sub-Saharan Africa is employed in agriculture. Nevertheless, the productivity of the sector is relatively low in comparison with other regions of the world. Based on convergence theory, technology transfer can enhance growth. However, the effective transfer of technology requires a certain absorption capacity from the recipient. Based on the qualitative research on cassava production in Congo Brazzaville, we identified key factors that influence the transfer process. These factors have been divided into four key areas: market, institutions, technology, and social capability. Cassava production value chain in Ignie region served as a case study for the evaluation of technology transfer absorptive capacity in Congo agriculture. We learned that the lack of agro-technical education, shortages in infrastructure, unavailability of business services, and market structure are among the main barriers of the intensification of technology use in agriculture.
W krajach Afryki Subsaharyjskiej znaczna część ludności zatrudniona jest w sektorze agrarnym, ale jego wydajność i poziom technologiczny pozostają stosunkowo mało rozwinięte w porównaniu z innymi regionami świata. Potencjalnym sposobem na przezwyciężenie problemów rolnictwa jest transfer technologii oraz wykorzystanie efektu konwergencji. Efektywność tego procesu jest jednak zależna od możliwości absorpcji technologii. Celem artykułu jest zidentyfikowanie kluczowych czynników wpływających na wykorzystanie technologii w rolnictwie subsaharyjskim na przykładzie upraw manioku w Kongu. Na podstawie badań jakościowych (wywiady bezpośrednie, obserwacje) przeprowadzono analizę uproszczonego łańcucha wartości produkcji manioku w Kongu. Stwierdzono występowanie istotnych barier o charakterze rynkowym, technologicznym, instytucjonalnym i społecznym, wpływających na możliwości absorbowania technologii. Chodzi przede wszystkim o braki dotyczące poziomu wykształcenia ludności, dostępności rozwiązań infrastrukturalnych, struktury rynku oraz dostępności usług rozwoju biznesu, ale również o niewystarczające rozwiązania instytucjonalne obejmujące transfer technologii zarówno o charakterze komercyjnym, jak i niekomercyjnym.

Opis:
The paper undertakes an assessment of the economics of environmental pollution on cassava-based farmers’ health and production efficiency within the Lafarge cement concession area in Mfamosing, Akamkpa Local Government Area, Cross River State. Data for the study were sourced from 60 cassava-based farmers drawn from neighbourhood and non-neighbourhood locations and analyzed using descriptive statistics and stochastic production frontier techniques. The result showed that farming activities in the area have been dominated by females with an average age of 43 and 35 years of age and household size between 4 and 6 persons. Clearly, the results indicate that cement plant activities have reduced farm productivity over the last 5 years, and has affected the livelihood of the farmers. The study also averred that respiratory diseases, diarrhea, skin rashes, heart disease, asthma, coughs and skin cancer have been the various health challenges suffered by the farmers. According to the study results, farmers lost 44 days due to heart disease, 33 days due to respiratory diseases, and 7 days due to diarrhea. The result of the maximum likelihood estimates (MLEs) of the stochastic frontier production function indicate that hired labour, quantity of fertilizer used and quantity of cassava stem cuttings were the significant variables that influenced cassava yield. The estimated technical efficiency (TE) ranged from 0.45 - 0.99, with a mean index of 0.67 (target group) and 0.57 – 0.99, with a mean of 0.82 (control group). The number of days lost due to illness was the most significant variable influencing inefficiency levels in the study area. It was, therefore, recommended that policies aimed at increasing efficiency should focus on improving health care services in the farming communities, while encouraging efficient level of pollution control by the prescribed cement factory, ab initio.

Opis:
In this work, the potentials of adhesives production from cassava starch were investigated. An adhesive product produced from Manihot utilissima was compared with a commercially available adhesive. Improvements in the properties of the cassava-based adhesive were achieved by investigating the effects of temperature and the addition of a viscosity enhancer/stabilizer (borax) on the density of the produced adhesive. The results obtained provide a wide range of insight into the production potentials of using cassava starch as a raw material in the production of large scale adhesives.

Opis:
Cassava peel has shown the potential of been efficient as a carrier material for biofertilizer production. Cassava peels are in large quantity and practically of no economic value in many developing nations, thus, satisfy criteria for its adoption as a biofertilizer-carrier material. The study evaluated the potential of cassava peel as a biofertilizer nutrient carrier and its effect on maize growth. Cassava peel has been found to have low moisture content and bulk density, high porosity and good water absorption capacity which aids inoculant organism survival as indicated in the significant (p< 0.05) increased in plant growth parameters, which stands higher (p < 0.05) over the control, with highest plant height and number of leaves produced at an application rate of 12t ha-1 biofertilizer.

Opis:
The present study is aimed at investigating the properties of Cassava starch for the production of adhesives as a career opportunity in chemistry education. Method of starch extraction, characterization and adhesive production for quality assessment was performed. The results showed that adhesives produced with sodium hydroxide as a gelatinization enhancer has a maximum drying time of 8.60 minutes and had a stronger bond. The work concludes that the adhesive produced is of good quality and can lead to re-inventing chemistry education as a career opportunity. However, the Cassava adhesive met the basic requirement for adhesive use and application. At the end recommendations were made, among others increase employment opportunities, also diversify the economic base of farmers and there is need for reorientation and attitudinal change towards entrepreneurial job.

Opis:
Biogas is produced during anaerobic digestion (AD) of biodegradable organic materials and is considered a promising renewable energy resource. Feedstocks are essential to ensure the successful anaerobic digestion in biogas digesters. Therefore, the search of appropriate substrates has come into focus. In this study, we examined the potential substrates that could be used as feedstock for the successful operation of an anaerobic digester. The approach used in this study was to identify the potential feedstocks that can be converted into value-added products. The identification of the feedstocks was done based on classification and evaluation of the theoretical biogas and methane production during the digestion process. The results show that all the considered substrates exhibited the biogas theoretical yield, with cattle manure producing the highest yield (0.999 m3/kg VS), whereas the lowest biogas yield (0.949 m3/kg VS) was obtained from cassava peels. It was concluded that the use of cassava co-digested with fruit and vegetable waste as an alternative feedstock offers a greater potential in terms of biogas production and could thus be implemented in the biogas projects running with cow dungs inside South Africa, especially in rural communities.
