Genotypic differences in body weight and physiological response of local and exotic turkeys challenged with Salmonella typhimurium
(2021-11-02)
To 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 ...

Agricultural risk assessment to enhance the food systems of the Mbororo minority community in the Northwest region of Cameroon
(2021-10-29)
Increasing 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 ...

Rainfall erosivity, soil erodibility and natural water erosion potential in the Huambo region, Angola
(2021-12-06)
The use of erosion assessment methods is critical for the sustainability of land use in tropical and subtropical regions, especially in countries lacking national information on soil erosion development, which is the case of Angola. This study aimed to evaluate the rainfall erosivity (R), soil erodibility (K), soil loss tolerance (T) and natural erosion potential (NEP) in Huambo (Angola). The R value estimated for a 25-year period was 7463 MJ·mm·ha-¹·h-¹·y-¹. K values estimated from 25 soil profiles, described in the ...

Determinants of Willingness to Pay (WTP) for organic fertiliser: a case of smallholder potato farmers in KwaZulu-Natal, South Africa
(2021-12-01)
The South African smallholder sector is characterised by relatively low productivity due to persistent deterioration in soil fertility owing to declining organic matter and other essential soil nutrients. Consequently, adoption of sustainable agricultural inputs like organic fertiliser is essential. Although there is sufficient advocacy in the adoption of organic fertiliser, the economic linkage between farmers' socioeconomic factors and willingness to pay (WTP) remains under-explored. This study investigated the ...

Drivers of adaptation to climate change in vulnerable farming communities: a micro analysis of rice farmers in Ndop, Cameroon
(2021-11-04)
Farmers in developing economies often struggle to adapt to climate change and their decisions to adapt usually hinges on perception and prevailing socio-economic factors. This study examines factors controlling farmers’ decision to adapt to climate change and evaluate the impact of such decisions on farm output. Using primary data from 138 rice farming households in Ndop-Cameroon, we employ the probit model with endogenous switching regression to investigate the impact of the farmers’ adaptation decisions on output. ...

Optimising beekeeping development programs for improved productivity, income and welfare: a case study of Papua New Guinea
(2020-10-19)
Beekeeping can provide important sources of cash income for farmers in developing countries where land is unconducive to crop and livestock production systems. In many low-income countries however, attrition among beekeeping adopters remains a chronic problem, colony losses are high, support for and coordination of the sector is low, and practices, production and income from beekeeping is often inefficient. This study investigated the key drivers and practices influencing incomes from beekeeping, honey production and ...

Forage biomass availability, species diversity and seasonal variation in grazing behaviour of cattle in the outskirts of Ouagadougou
(2020-10-14)
In order to determine the exploitation of grazing areas in the outskirts of Ouagadougou by cattle herds, the grazing behaviour of cows was monitored in five villages in these during three distinct seasons, namely wet, cool dry and hot dry season. A vegetation study including a census of the woody and herbaceous stratum of grazing areas allowed for an assessment of the pasture biomass availability during the wet season. Results of the monitoring of cattle herds showed that the land type grazed by cattle in the outskirts ...

Gender differences in time-poverty among rural households in Southwest Nigeria
(2021-10-29)
This 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 ...

Tillage system and integrated soil fertility inputs improve smallholder farmers’ soil fertility and maize productivity in the Central Highlands of Kenya
(2021-09-20)
We designed and implemented an on-farm trial in Meru South and Gatanga sub-counties to understand the effects of integrated soil fertility management (ISFM) technologies on soil nitrogen (N), phosphorus (P), potassium (K), and maize productivity. The technologies included combinations of mineral fertiliser and maize stover (CrMf); crop residue, Tithonia diversifolia and rock phosphate (CrTiP); crop residue, Tithonia diversifolia and goat manure (CrTi-Man); crop residue, inorganic fertiliser and goat manure (CrMfMan); ...

Drivers of farmers market participation in southeast Nigeria
(2020-10-29)
The objective of this paper was to investigate the drivers of farmers’ participation in the output market for yellow pepper using a sample of 420 randomly selected producers from 8,500 farmers in selected markets in southeast Nigeria. The heterogeneity of smallholder market participation was modelled with quantile regression. The variables that affected all the quantiles (i.e. for subsistence, semi-subsistence, intermediate, semi-commercial and commercially oriented farms) are the distance to the trading centre and ...
