Opis:
This study was designed to examine the feasibility of recycling cassava effluent, sawdust, and unused paper products to enhance their utilization for beneficial purpose. Waste newspaper paste (WNP), Waste writing-paper paste (WWP), and Waste carton paper paste (WCP) were prepared and then used separately to similarly fabricate composite panels with Sawdust particle (SDP) proportioned at 0%, 25%, 50%, 75%, and 100% by weight. The binder used was cassava starch slurry prepared from the effluent. Bulk density, water absorption, thermal conductivity, specific heat capacity, thermal diffusivity, nailability, and flexural strength were determined for the developed samples. From the results obtained, the samples were found to be light-weight and their thermal insulation performance improved with increasing proportions of the SDP. Though samples containing the WCP exhibited the best satisfactory performance, it was found that all the studied samples could perform more effectively and efficiently as ceilings compared to some of those reported in the literature. From scientific-economic viewpoint, valorizing the above-mentioned wastes as described in this paper could help to protect the environment and also yield value-added insulation ceilings for enhancement of sustainable building construction especially in tropical areas.
Celem pracy było określenie możliwości recyklingu ścieków z manioku, trocin i odpadowych materiałów papierniczych w celu ich szerszego wykorzystania. Nitki z makulatury gazetowej (WNP), nitki z makulatury z papieru do pisania (WWP) i nitki z makulatury z kartonu (WCP) zostały przygotowane, a następnie użyte osobno do wytworzenia paneli kompozytowych z dodatkiem trocin (SDP) przy udziale masowym 0%, 25%, 50 %, 75% i 100%. Zastosowanym spoiwem była przygotowana z odcieku zawiesina skrobi z manioku. Dla przygotowanych próbek określono gęstość nasypową, nasiąkliwość, przewodność cieplną, ciepło właściwe, dyfuzyjność cieplną, zdolność do wbijania gwoździ i wytrzymałość na zginanie. Na podstawie uzyskanych wyników stwierdzono, że próbki miały małą gęstość objętościową, a ich właściwości termoizolacyjne poprawiały się wraz ze wzrostem udziału trocin (SDP). Chociaż próbki zawierające WCP wykazywały najlepsze właściwości, stwierdzono, że z wszystkich badanych próbek można wytworzyć sufity o lepszych właściwościach w porównaniu z podobnymi opisanymi w literaturze. Z naukowo-ekonomicznego punktu widzenia zastosowanie wyżej wymienionych odpadów, jak opisano w tym artykule, może pomóc w ochronie środowiska, a także w uzyskaniu bardziej ciepłochronnych stropów, a co za tym idzie przyczyni się do rozwoju bardziej zrównoważonego budownictwa, zwłaszcza w obszarach tropikalnych.

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:
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:
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.

Fluctuation in prices of Agricultural products is inevitable in developing countries faced with economic depression and this, has brought a lot of inadequacies in the preparation of Government financial budget. Consumers and producers are poorly affected because they cannot take appropriate decision at the right time. In this study, Machine Learning(ML) predictive modeling is being implemented using the MATLAB Toolbox to predict the price of cassava derivatives (garri) in the South Western part of Nigeria. The model predicted that by the year 2020, all things being equal, the price of (1kg) of garri will be 500. This will boost the Agricultural sector and the economy of the nation.

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 microorganism associated with cassava fermentation for producing Abacha was investigated using four different Farms in Owerri (Obinze, Umugwuma, Urata and Orji) as sample collection areas. Four of the cassava tubers that harvested, were washed, cooked and soaked with water after cutting to produce Abacha, which was then fermented using standard microbiological methods. The wastewater was subsequently sampled. All the samples A, B, C, and D showed significant bacteria growth after application of NA, MRS, PDA. In the study, six bacteria and fungi isolates were identified: Escherichia coli, Staphylococcus aureus, Lactobacillus spp, Candida spp., Aspergillus spp. and Bacillus spp. Results showed that the total heterotrophic bacteria count of the sample varies within 8.0×1010 to 2.5×1012 and total fungi count (TFC) ranges from 6.6×109 to 9.6×109. The study also showed that Lactobacillus spp. and Escherichia coli had the highest prevalence occurrence of 75.00% (P < 0.05), while Staphylococcus aureus, Saccharomyces spp., Bacillus spp. and Candida spp. had a percentage occurrence of 50.00%, respectively. There is, therefore, urgent need for public enlightenment on public health implications, need for proper hygiene, as well as need for strategies for preventing and controlling the microorganisms which do not play a role in the fermentation of cassava for Abacha production.

The ability of NaOH-activated carbon derived from cassava peels waste to remove MY from aqueous solution was carried out in a fixed-bed column adsorber. The parameters studied included initial solution concentration, Co, carbon bed height and volume flow rate. The temperature of operation and initial solution pH were 29 °C and 5.32, respectively. The optimum adsorption capacity, qe 4.12 mg/g was obtained at Co 10mg/L, bed height 10cm and flow rate, 13.3ml/min. Experimental data were analyzed with Langmuir, Freundlich and Temkin isotherm, as well as the Thomas, Yoon-Nelson and Clark kinetic models. All the models were good fits for experimental data based on correlation coefficient, R2 values. The ΔGads and Freundlich n (1.587) show that the biosorption was spontaneous, good and physical. Results show that NaOH-activated carbon from cassava peels has low capacity to remove MY from aqueous solutions.

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:
A comparative analysis of the efficiency of activated carbon produced from fermented cassava peels (CPB), unfermented cassava peels (CPA) and commercial grade activated carbon (CAC) in the treatment of refinery wastewater was carried out. CPB was found to be 8% and 18% more efficient when compared to CPA and CAC in the removal of COD, and 14% and 3% better than CAC and CPA respectively in the removal of BOD5. The removal efficiency of Pb2+ by CPB was 100% compared to 95% and 57% by CPA and CAC while 96% of phenol was removed by CPB against 93% and 83% by CPA and CAC respectively. This better performance of CPB over CPA and CAC is not unconnected with its higher pH resulting from the removal of cyanide from the peels during the fermentation process. However, despite the high phenol removal efficiency by CPB, the concentration of phenol in the treated effluent does not meet the environmental guidelines for disposal. It is therefore, recommended that a two-stage CPB adsorption column arranged in series is necessary to treat refinery wastewater efficiently if it is desired to totally remove phenol from the effluent or reduce the concentration to 0.005 mg/l allowed by the Federal environmental protection agency (FEPA). The equilibrium adsorption test conducted showed that the Freundlich isotherm is a better fit for the adsorption of phenol by the three activated carbons with correlation coefficients (R2) of 0.9364, 0.9383 and 0.9541 for CAC, CPA and CPB respectively. CPB was found to be a better adsorbent as it has the highest adsorptive capacity as evidenced from its better Freundlich exponent.

Opis:
The significance of rural poverty is underscored by the fact that a high percentage of the national population resides in the rural areas, is poor, and dependent on agriculture. The aim of this study is therefore to analyse the determinants of poverty status among cassava growing households in Oyo State, Nigeria. The specific objectives were to describe the socio-economic characteristics of the respondents, analyse the determinants of poverty status among the respondents, and examine the poverty profile of the respondents based on their income class. Descriptive statistics, Probit Regression analysis and Foster-Greer-Thorbecke (FGT) poverty measures were used to analyse the objectives, respectively. The result shows that number of years spent in school, household size and household assets were found to be the significant determinants of the poverty status of the respondents. Household size had a negative eff ect on the household’s poverty status, while household assets and years of schooling had positive effects on status. The results of the FGT measures show that poverty incidence, depth and severity are higher in the low-income class than in the high-income class. In conclusion, farmers who are members of larger households, those with little or no formal education and those with minimal assets were poorer than others. It is therefore recommended that a family-planning campaign and farmers’ educational programs should be intensified in the study area.
Występowanie ubóstwa na obszarach wiejskich ma tym większe znaczenie, że zamieszkuje je duży procent populacji, panuje tam bieda i powszechna zależność od rolnictwa. Celem artykułu było wskazanie czynników ubóstwa rolników uprawiających maniok w stanie Oyo, w Nigerii. Do celów szczegółowych zaliczono: socjoekonomiczną charakterystykę respondentów, analizę czynników ubóstwa oraz określenie profi lu ich ubóstwa na podstawie poziomu dochodów. W celu przeprowadzenia odpowiedniej analizy zastosowano statystyki opisowe, analizę regresji logistycznej oraz miarę FGT (Foster-Greer-Thorbecke). Jak wskazują wyniki, liczba lat nauki, wielkość gospodarstwa domowego oraz jego zasoby to kluczowe czynniki wpływające na status ubóstwa respondentów. Wielkość gospodarstwa domowego ma negatywny wpływ na sytuację ekonomiczną, podczas gdy posiadane zasoby i lata nauki oddziałują pozytywnie. Miary FGT pokazują, że występowanie ubóstwa, jego stopień i wielkość zależą wprost od poziomu dochodów. Podsumowując, rolnicy prowadzący większe gospodarstwa domowe, słabo wykształceni (lub bez wykształcenia) oraz ci, którzy dysponują najmniejszymi zasobami, są biedniejsi niż pozostali. Zaleca się zatem zintensyfikowanie na badanym obszarze kampanii dotyczących planowania rodziny oraz programów edukacyjnych dla rolników.
