Primary data obtained from 362 farmers, 125 extension officers and 14 researchers from the three agro-ecological zones of southwest Nigeria were used to examine the technological and farming systems adaptation to climate change. The data obtained were organised in Microsoft Excel, cleaned and analysed on the Statistical Package for the Social Sciences (SPSS). Most of the farmers are married, formally educated, male Christians with an average age of about 49 years and a household size of 9 persons. The extension officers are mainly married, male, Christians holding a Higher National Diploma (HND) or a B.Sc. and working about 250 farmers each. Half of the researchers are based in Ibadan where most of the research institutes in southwest Nigeria have their main offices. There is a high level of climate awareness among farmers and extension officers. Only location (agroecological zone) provides a significant insight into the variability in farmers' observation among the variables tested. Most of the farmers (65.75%) opine that farming activities such as bush burning, use of agro-chemicals and deforestation contribute to climate change, and some other farmers (96.6% in the swamp zone, 60.8% in the rainforest and 68.3% in the savanna) opine that the main climate change effect on their personal lives is reduction in personal productivity. In terms of climate change effects on farming enterprises, reduction in crop yields was reported by 60% of the farmers. The main strategies and technologies promoted by extension officers to assist farmers to cope with the effects of climate change in southwest Nigeria are: tree planting (30%), timely planting of crops (6%) and avoidance of bush burning (6%) in the swamp zone. In the rainforest zone, it is provision of small scale irrigation (25%), mulching (16.7%) especially on yam farms, and avoidance of felling trees (8.3%). In the savanna zone the main coping strategies and technologies are: avoidance of tree felling (25.6%), avoidance of bush burning (23.1), small scale irrigation (5.15) and studying weather condition before planting crops (5.1%). The study concluded that there is a general conviction among farmers, extension officers and researchers that crops and forests management technologies are the main tools for adapting to climate change. It is noteworthy however that adapting to climate change is as much a technology issue as an attitudinal one. Emerging and Indigenous Technology for Climate Change Adaptation in Southwest Nigeria | 5

A five-week experiment was conducted to investigate the effect of dietary supplementation of two varieties of cassava root meal (CRM) with various additives on growth performance and reproductive traits of pullets. Two hundred and forty 16-weeks old point of lay birdswere allotted to eight dietary treatments in a 2x4 factorial arrangement of white (TME 419) and yellow (ITA/IBD/1368) CRM supplemented with no additive, amino acids (methionine and lysine), enzyme and amino acids+enzyme (A.A+Enz). Growth measurements were recorded from 17 weeks till the start of lay at 21 weeks old and data on reproductive traits were also recorded in each treatment. Variety effect showed improved (p<0.05) live weight gain at a reduced cost in growing pullets fed with diets containing white cassava than yellow. Supplementing white cassava root meal (WCRM) and yellow...

Interview guides were used to elicit information from selected 370 goat farmers obtained through multi-staged sampling method. Findings revealed that the mean age of goat farmers was 50.7 years and 55.4% had formal education. Majority (35.4%) of respondents fed combination of grass, cassava and kitchen wastes to their goats followed by 32.4% that fed cassava peels and root. Majority (91.9%) of respondents believed that cassava does not harm their goats, though 74.3% indicated that it has toxin. About half (57.3%) of respondents had low knowledge of cassava nutrients and toxicity while 93.0% of them had low knowledge of signs and symptoms of cassava poisoning in goats. Most of the farmers (51.9%) processed cassava waste by sun-drying. There were significant relationships (p<0.05) between household size (?2=57.2; df=8), education (?2=82.5; df=10), f...

The specific objectives are to: analyse important sources of uncertainty influencing HQCF value chains; explore stakeholders’ strategies to respond to uncertainty; and highlight the implications of different adaptation strategies for equity and the environment in the development of the value chain. Design/methodology/approach The authors used a conceptual framework based on complex adaptive systems to analyse the slow development of the value chain for HQCF in Nigeria, with a specific focus on how key stakeholders have adapted to uncertainty. The paper is based on information from secondary sources and grey literature. In particular, the authors have drawn heavily on project documents of the Cassava: Adding Value for Africa project (2008 to present), which is funded by the Bill & Melinda Gates Foundation, and on the authors’ experien...

Thirty West African dwarf goats (8.00 ± 0.13 kg) were divided into five treatment groups of six (6) animals per group and randomly allotted to one of the five diets supplemented with (1). no dietary antioxidant (control); (2). Vitamin E (200mg/kg of feed); (3).Vitamin C (600mg/kg of feed); (4). 200mg Vitamin E+ 0.2mg Selenium/kg of feed; (5). 600mg Vitamin C+ 0.2mg Selenium/ kg of feed respectively, in a completely randomized design. The results revealed that dietary antioxidant supplementation significantly (p<0.05) influenced the red blood cell (RBC) with higher values in selenium supplemented groups, white blood cell (WBC) and basophil counts. Albumin, glucose and alanine transaminase (ALT) significantly (p<0.05) differed across the diets. The significantly (p<0.05) reduced thiobabutiric acid substance (TBARS) in supplemented groups compared to the control justified the scavenging characteristics of the supplemented antioxidants. Furthermore, cholesterol, uric acid, glutathione (GSH), glutathione S -tranferase (GST) and superoxide dismutase (SOD) activities were oxidative biomarkers significantly (p<0.05) influenced by the antioxidants supplementation while bilirubin and Vitamin E were similar across the treatments. The findings of this study revealed that Vitamin E, Vitamin C and their combination with Selenium did not only enhance erythrocyte formation but improved immune response and health status as well as the oxidative status of the goats by reducing the activities of TBARS and increasing the activities of SOD, GSH and GST.

Forming groups of farmers which are guided by lead farmers who are trained first and who in turn train the group farmers has enormous benefits in technology transfer. Nurturing and educating the farmers in groups could have considerable impact on the farmers income and welfare through increased quantity and quality of outputs.

The main issues discussed include: competiveness in the supply of raw material, assisting smallholders to produce value-added products sustainably and competitively, ensuring and maintaining quality of products, selecting appropriate technologies for different circumstances and anticipating negative effects of the market environment on smallholders. One of the main challenges for value addition to a staple crop in Africa is finding 'champions' who are willing to make new investments with knowledge, skill and expertise requirements derived from other nations. The other is increasing the drying capacities for a tropical root crop through appropriate technologies that ensure production of high quality products in required volumes. One focus of the C:AVA project in the near future is to promote transfer of energy efficient Nigerian-made flash drier in collaboration with partners and fabricators from other C:AVA countries (Ghana, Uganda, Malawi and Tanzania). Improved energy efficiency will reduce fuel consumption, reduce operating cost and improve throughput of the dryers. An additional benefit will be reduction in emission of harmful greenhouse gases and their impact on global warming. It is anticipated that the knowledge and skills for further developing the value addition potential for cassava in all five countries will be enhanced. Benchmarking of key variables was used as an approach to understand differences between countries in terms of their abilities to develop high quality cassava flour value chains. It is clear that one strategy does not work in all countries and while positive government support for cassava development is helpful, the real driver is targeting markets according to realisable capacities of the smallholder actors in the value chain

Cassava (Manihot esculenta) production in Nigeria is estimated to be 34 million tonnes per annum ... more Cassava (Manihot esculenta) production in Nigeria is estimated to be 34 million tonnes per annum and has dramatically increased since 1986. Fufu is a fermented cassava product that is traditionally consumed in Nigeria and other West African countries. It is prepared by peeling roots, washing, cutting into pieces and steeping in water to ferment for 3-4 days. The fermented mash is pounded or simply washed over a fine sieve to remove fibre and the water expelled from the starch extract by pressing through muslin cloth to produce fufu (Oyewole and Sanni 1995). Fufu is considered by consumers to be of good quality when it has a smooth texture, characteristics aroma and is creamy-white, grey or yellow in colour (Akingbala et al., 1991). The quality of fufu, however, varies with processors and season (Oyewole and Sanni, 1995). The variability in fufu has been attributed to various local practices by the processors (Sanni et al. 1998; Sanni, 1999; Oyewole et al., 2001).

This study therefore examined the key issues in the uptake of agricultural knowledge and information in Nigeria by using primary data obtainedfrom a sample of 77 systematically selected smallfarmers in Ogun State. This was complemented with available datafrom the Central Bank of Nigeria as input into the Nigerian Small Farmer Adoption Model (NSFAM) to demonstrate the key roles that agricultural knowledge and information analysis play among farmers, agricultural planners, extension practitioners, researchers andfunding agencies. The study used the counter-intuitive predictions of the model to shed some light on critical questions that needs to be asked before scarce resources are committed to agricultural transformation efforts. It then posited that a key lessonfor the main actors in the agricultural information management process (planner, researchers and extensioners) is that i...

The data were subjected to both descriptive and inferential statistical analyses. The study found that both native and non-natives are involved in cassava processing, but processors across the selected States differ in their membership of groups. Almost all the cassava processors interviewed in Oyo State belonged to Gari Gbayi, the umbrella association for all cassava processors in the State. Of the 265 cassava processors, 57.74% adopted the cassava grater and 50.19% adopted the screw press. The adopters of cassava grater are older, with larger household sizes and stayed longer in school than the non-adopters. They also have longer cassava processing experience and run larger cassava processing enterprises wher...

Primary data obtained from 112 respondents selected from the 4 extension zones of Ogun State was used to examine the perception of effectiveness of innovations by cassava processors and the factors responsible for adoption of these innovations. The processors’ perception of effectiveness of cassava processing innovations was measured on a 5-point Likert-type scale containing 20 items. Most of the respondents (75%) are indifferent in their perception of the effectiveness of innovations in cassava processing. All the cassava processing innovations considered in this study are known to some respondents, but their levels of use and acquisition differ from one innovation or the other. There are no significant relationships between the processors’ perception of effectiveness of cassava process...

Thirty West African dwarf goats (8.00 ± 0.13 kg) were divided into five treatment groups of six (6) animals per group and randomly allotted to one of the five diets supplemented with (1). no dietary antioxidant (control); (2). Vitamin E (200mg/kg of feed); (3).Vitamin C (600mg/kg of feed); (4). 200mg Vitamin E+ 0.2mg Selenium/kg of feed; (5). 600mg Vitamin C+ 0.2mg Selenium/ kg of feed respectively, in a completely randomized design. The results revealed that dietary antioxidant supplementation significantly (p<0.05) influenced the red blood cell (RBC) with higher values in selenium supplemented groups, white blood cell (WBC) and basophil counts. Albumin, glucose and alanine transaminase (ALT) significantly (p<0.05) differed across the diets. The significantly (p<0.05) reduced thiobabutiric acid substance (TBARS) in supplemented groups compared to the control justified the scavenging characteristics of the supplemented antioxidants. Furthermore, cholesterol, uric acid, glutathione (GSH), glutathione S -tranferase (GST) and superoxide dismutase (SOD) activities were oxidative biomarkers significantly (p<0.05) influenced by the antioxidants supplementation while bilirubin and Vitamin E were similar across the treatments. The findings of this study revealed that Vitamin E, Vitamin C and their combination with Selenium did not only enhance erythrocyte formation but improved immune response and health status as well as the oxidative status of the goats by reducing the activities of TBARS and increasing the activities of SOD, GSH and GST.

The mean age and cassava processing experience were 53.01 and 22.76 years respectively. About 23.0% of the processed cassava tubers constituted peels. The study also revealed that 50% of the cassava processors discarded peels as waste, 26% sold generated peels while 24% fed the peels to their livestock. Also 93.5% of the cas...

The data were subjected to both descriptive and inferential statistical analyses. The study found that both native and non-natives are involved in cassava processing, but processors across the selected States differ in their membership of groups. Almost all the cassava processors interviewed in Oyo State belonged to Gari Gbayi, the umbrella association for all cassava processors in the State. Of the 265 cassava processors, 57.74% adopted the cassava grater and 50.19% adopted the screw press. The adopters of cassava grater are older, with larger household sizes and stayed longer in school than the non-adopters. They also have longer cassava processing experience and run larger cassava processing enterprises wher...

Thirty West African dwarf bucks aged 8±1.3 months with an average body weight of 6.06±0.02 kg were used in a completely randomized experiment. The goats were randomly assigned to one of the five dietary treatments which consisted of milled cassava peels, cassava leaves and cowpea haulms in different ratios of 700:100:175 (T1); 500:200:275 (T2); 300:300:375 (T3) and 100:400:475 (T4) g/kg DM respectively. A standard diet formulated to meet the nutrient requirements of the animals with no cassava and cowpea haulms was used as the control diet (T5). Data collected was subjected to analysis of variance using the general linear model procedure of SAS. The results obtained indicated that the highest dietary crude protein was obtained in treatment 5 (206 g/kg) followed by treatment 4 (200 g/k...

Two hundred and forty 21-week-old (Isa Brown®″ strain) laying birds were allotted to 8 dietary treatments in a 2 × 4 factorial arrangement of white (TME 419) and yellow (ITA/IBD/1368) CRM supplemented with no additive, amino acids (methionine and lysine), enzyme, and amino acids + enzyme (AA + Enz). The experiment was partitioned in 3 phases: 0-10 weeks, 11-20 weeks, and 21-30 weeks in lay. Variety effect showed improved (p < 0.05) egg production in layers fed with yellow cassava than those fed the white variety. Supplementing yellow cassava root meal (YCRM) and white cassava root meal (WCRM) with AA + Enz from 0 to 10weeks in lay and 11 to 30weeks in lay, respectively, resulted in superior egg production performance at a reduced cost. Feeding the layers...

Primary data obtained from 112 respondents selected from the 4 extension zones of Ogun State was used to examine the perception of effectiveness of innovations by cassava processors and the factors responsible for adoption of these innovations. The processors’ perception of effectiveness of cassava processing innovations was measured on a 5-point Likert-type scale containing 20 items. Most of the respondents (75%) are indifferent in their perception of the effectiveness of innovations in cassava processing. All the cassava processing innovations considered in this study are known to some respondents, but their levels of use and acquisition differ from one innovation or the other. There are no significant relationships between the processors’ perception of effectiveness of cassava process...
