A review of the literature on gender and chemical fertiliser use in maize production in sub-Saharan Africa
Get PDFAre there differences in men’s and women’s access to and use of fertiliser in sub-Saharan Africa? This article explores the issue through a systematic review of the extant literature on gender and fertiliser use in maize production. The findings show that indeed a gender gap in the use of fertiliser exists. More than a decade after the World Bank identified a gender gap in fertiliser use, there are no systematic national or global data sets comparing fertiliser use by gender. While farm input subsidies can improve women farmer’s access to fertiliser and have a positive effect on agricultural productivity for both men and women farmers, this approach has little effect on reducing the gender gap in agricultural productivity. The challenges associated with gender and fertiliser access and use are complex and there is no silver bullet intervention that can address the problem, particularly in relation to intra-household dynamics and social norms. Thus solving the noted problem, will require a holistic approach rather than “simple” sectoral interventions. Over time, suboptimal fertiliser use depletes soils. Nutrient use efficiencies worsen under soil nutrient mining and degradation, thus economic incentives for fertiliser investments are also eroded in such situations, resulting in a vicious cycle. The development of nutrient use efficient maize seed technologies could be an intermediate step
Assessment of pond and integrated aquaculture (IAA) systems in six districts of Tanzania
Get PDFIntegrated agriculture and aquaculture systems (IAA) are well known for their ability to improve the overall farm productivity and profitability. This is through recycling of on-farm resources, such as nutrient rich fish pond water and agriculture remains that would otherwise be considered as wastes. The present study explores the existing and potential IAA systems in Tanzania. It also examines management strategies and their influence on fish yield and the economic returns between IAA and non-IAA fish farming. The study assesses farmer’s socio-demographic characteristics and their perception towards fish farming. The study was conducted through an on-site survey of 129 fish ponds owned by 89 farmers in six districts in Tanzania, involving 65 and 64 IAA and non-IAA ponds respectively. Results indicate that tilapia-vegetables is the most common type of IAA practiced by fish famers. Despite higher fish feed use and stocking density in non-IAA ponds, IAA ponds had an average fish yield of 2.46 t ha-1, which was significantly (p0.05) higher than the fish yield of 1.54 t ha-1 found for non-IAA ponds. IAA ponds had also 1.6 and 2.9 times higher (p 0.05) revenue and net profit, respectively, than non-IAA ponds. Additionally, the net return from IAA ponds in an integrated system was significantly (p0.05) higher than when practiced as stand-alone activities. IAA famers were more positive towards fish farming compared to non-IAA farmers. Thus, IAA systems should be promoted among small-scale farmers to cover for an increased fish demand and to improve food security
Choice of savings instruments among rural women maize farmers: evidence from Uganda
Get PDFHouseholds in developing countries employ a wide range of mechanisms for making cash and in-kind (goods and services) savings which are either formal or informal. Yet, literature on how choices about appropriate savings instruments are made remains scanty. We examine the patterns and choice of these saving instruments using household data from women farmers in eastern Uganda. In particular, the paper focuses on the choice between formal cash saving instruments like commercial banks, village savings and loans associations (VSLAs) and savings at home. A multinomial logit model was applied to identify and quantify the effects of socio-economic factors on farmers’ choice of different savings instruments. The results reveal that financial capital and socio-economic factors such as age, education, farm size, and level of maize commercialisation were the critical drivers of women maize farmers’ choices of saving in informal and formal instruments
Gender differences in time-poverty among rural households in Southwest Nigeria
Get PDFThis study seeks to assess gender inequality in and correlates of time poverty among 360 rural households in Southwest, Nigeria. A person is deemed to be time poor if (s)he works more than 10.5 hours per day, the internationally accepted threshold. Using the time allocation domain of the Abbreviated Women’s Empowerment in Agriculture Index, the study found that on the average, rural women and men spent about 10.3 hours and 8 hours, respectively, on work activities on a daily basis. Work activities for women were found to be diverse, spreading across reproductive and productive domains largely farming, own business e. g. trading, cooking and domestic work, while for men, work activities centred on productive economic activities, dominated by farming. Using a Probit regression model, the study found experience in agriculture and adoption of television to reduce the likelihood of time poverty among rural men. Surprisingly, participation in empowerment projects was found to increase the likelihood of time poverty among rural women. In conclusion, empowerment programmes should be expanded to address the non-material aspects of human well-being. Hence, the study recommends a gender-sensitive approach to intervention programmes in agriculture and adoption of a broader definition of empowerment which not only focus on expanding access to markets and increasing income but enhances control over time. This is more important for women who are already under the double burden of paid and unpaid domestic work
Demonstration of improved feed trough for efficient feed utilisation by small ruminants in Southern Mali
Get PDFThe ruminant feeding systems of smallholder farmers in mixed crop and livestock systems in Sudano-Sahelian zone of West Africa are characterised by waste. To promote efficient feed use, the use of improved feed trough for small ruminants was demonstrated in Sirakele, Zanzoni and M’Pessoba in Koutiala district in southern Mali in the late (March/April 2019) and early dry (February 2020) seasons. Forty-five farmers were selected randomly in the study sites and were each provided with one improved feed trough which was then compared with the conventional or commonly used feed trough. The quantity of feed offered, and that was wasted during the feeding were measured for six consecutive days, both for the conventional and improved feed troughs. The perceptions of all participating farmers about the technology were documented through response to a series of questions on the potential benefit of the improved feed trough based on the five-point Likert scale. The results showed that the improved feed trough reduced feed waste significantly in all the three sites in both seasons. The percentage of waste in feeding crop residues to sheep and goats using the conventional feed trough were 7.73 ± 0.9, 26.13 ± 3.3, and 13.32 ± 1.4 in Sirakele, Zanzoni and M’Pessoba, respectively in the late dry season compared to less than 1% with the improved feed troughs during the same season in Sirakele and M’Pessoba, respectively while it was 3.33% in Zanzoni. Feed saved by using improved feed trough gave net return of 13,020, 12,384 and 17,892 FCFA/household/year for Sirakele, Zanzoni and M’Pessoba, respectively. The participating farmers confirmed the benefits of the improved feed trough which are consistent with our results
Determinants of protected tomato production technologies among smallholder peri-urban producers in Kiambu, Kenya
Get PDFClimate variability and the rise in incidences of pests and diseases continue to undermine production of high value vegetables among smallholder farmers in sub-Saharan Africa. In order to respond to these challenges, protected farming technologies (PFT) (such as greenhouses) which modify the plant environment and therefore aid in avoiding the harmful eects of climatic factors have been promoted. Greenhouses protect the crops against high solar radiation and heavy rainfall that have the potential of destroying vulnerable crops like tomatoes. Consequently, PFT is associated with better yields and farm incomes. However, the adoption of PFT among smallholder farmers, not least in Kenya is low. Drawing on the Agricultural Household Model (AHM) theoretic framework, this paper assessed the determinants of adoption of PFT among smallholder tomato farmers in Kenya. Tomato is the second most important horticultural vegetable crop in Kenya after potatoes in terms of production volumes and value. Data for the study were collected from a cross sectional multistage random survey of 104 tomato farming households and analysed using maximum likelihood probit model. The probit results revealed that the age of a farmer, educational level, household size, total household income and access to credit positively influenced the likelihood of PFT adoption. The likelihood of adoption was negatively related to distance to input markets and access to the county government extension services. Overall, the results of this study suggest that an integrated promotional strategy that accounts for household heterogeneities and focuses on institutional arrangements that support the accumulation of human and financial capital would enhance PFT adoption
Genotypic differences in body weight and physiological response of local and exotic turkeys challenged with Salmonella typhimurium
Get PDFTo better understand susceptibility and/ or tolerance of locally adapted turkey to salmonellosis, we compared bodyweight, antibody titres and physiological traits based on genotype and sex of salmonella-infected turkeys. Three hundred poults from two genotypes (160 local and 140 exotic turkeys) were raised for twenty weeks. Bodyweight (BW), rectal temperature (RT), pulse rate (PR) and respiratory rate (RR) were measured weekly. Blood samples were collected from each turkey before and after inoculations at week 8 and 13 for serum antibody detection using enzyme-linked immunosorbent assay. Genotype had a significant (p 0.05) effect on all the parameters measured. Exotic turkey had higher weight than local while sexual dimorphism was in favour of toms despite challenge with Salmonella typhimurium. The RT was significantly higher (p 0.05) in exotic turkeys except at week 2, 6 and 8. In like manner, PR was higher (p 0.05) in exotic turkey except at week 4 (204.28±2.48 beats/minutes) and 8 (216.98±1.46 beats/minutes) where it was higher in local turkey. RR also followed the same trend while HSI was higher (p 0.05) in week 2 (1.53±0.06 breaths/minutes) and 14 (1.17±0.07 breaths/minutes) in exotic turkeys. Local turkeys had higher (p 0.05) antibodies against Salmonella organisms before and after inoculation while the hens of both genotypes had higher (p 0.05) antibody titres at the 7th day after inoculations. The present results seemed not to be convincing enough to suggest differences in tolerance/susceptibility to Salmonella infection and therefore the two genotypes may be equally adapted
Agricultural risk assessment to enhance the food systems of the Mbororo minority community in the Northwest region of Cameroon
Get PDFIncreasing population pressure, coupled with the effects of climate change manifested by longer dry seasons, wildfires, and conflicts, threatens the food systems of minority communities. In the case of the Mbororo minority community of Northwest Region of Cameroon, these threats are exacerbated by already existing problems of marginalisation. This study assesses agricultural risks in the global context of food distribution and gross domestic product that also poses a specific threat to the food system of the Mbororo people. The study aims to (1) assess the types of agricultural risk encountered by the Mbororo community, (2) examine the likelihood and severity of these risks, and (3) appraise local risk management strategies adopted to minimise the negative impacts of these risks on the food system. The study makes use of a mixed method approach for data collection. Findings have revealed animal diseases (83 %), absence of infrastructures (83.6 %), price variation (76.6 %), and drought (75.8 %) as the most encountered risks in the case study area. Especially, drought, political insecurity, pest and rodent, farmer-grazer conflict, and crop and animal diseases emerged as the highest intensity or priority risks with the need for urgent management strategies intervention. Agricultural risk assessment is frequently used to assess and prioritize risks but has hardly been used in the case of minority groups such as the Mbororo community of Northwest Cameroon
A comparative cost-benefit analysis between fairtrade certified and non-certified cocoa production in the South-West region of Cameroon
Get PDFIn order to promote cocoa agroforestry by encouraging cocoa farmers to integrate fruit trees inside their cocoa orchards, cocoa certification was initially launched since 2012 in Cameroon. Nowadays, cocoa certification is adopted by a few farmers and makes up only 3% of the national cocoa production. Using the most predominant Fairtrade certification in the South-West region, this study compared certified and non-certified cocoa production via a cost-benefit analysis. The results indicated that, in spite of its supplementary cost expenses (wages to hired workers, agrochemical expenses, transportation charges to cooperatives), certified cocoa production led to higher profit, net present value, internal rate of return, benefit-cost ratio greater than one and shorter pay-back period. For the certified farms, a scenario assuming no certification was analysed and its results testified that the young trees planted during cocoa certification further contributed to raise the farm profit. Overall, the profitability of cocoa agroforest was the highest if the farmer was certified, because of his/her premium earned, training received and adhesion to cooperatives where most group problems were solved. The study therefore recommended farmers to join cooperatives and regularly attend training programmes to learn more friendly environmental practices. In view of this, the government should increase cocoa premium or tie it with payments for full environmental benefits, including rewards for carbon sequestration and biodiversity conservation. The Fairtrade certification bodies should attract reticent farmers to certification by convincing them on the necessity to remove the old fruit trees and replace them with new species, which were more productive to raise their income.
A review of soil fertility management communication in sub-Saharan Africa
Get PDFIn sub-Saharan Africa (SSA), declining soil fertility is among the factors affecting optimal food production. Although a number of interventions have been implemented to improve soil fertility management (SFM) in SSA, their adoption especially among small scale farmers has been low. Although the literature provides considerable evidence of socio-economic factors which influence adoption, the subject of how communication influences adoption of SFM remains under-explored. This paper therefore reviewed studies on SFM communication in SSA. The objectives were to identify the current focus of studies on SFM communication, the current definitions of communication which informed such studies, and the type of SFM practices being communicated in the SSA region. Using specific search terms, articles were collected from various databases and content analysed. The review revealed five main themes as the focus of current studies on SFM. The study also revealed two main interpretations of communication which in turn influence the use of either diffusion or participatory communication strategies for SFM communication. The review also showed a focus on integrated soil fertility management (ISFM) messages in the SSA area. The study concludes that while each of the two communication strategies has their individual strengths, farmers prefer participatory strategies. This is because participatory strategies foster interaction and greater understanding; thereby, increasing the likelihood of farmer adoption of SFM practices in SSA. The review concludes by calling for further research on the use of participatory communication to engage farmers about various SFM practices in SSA
