Challenges related to beef-cattle pricing between a western block and a third world country

Abstract: This study considers a business scenario involving three participants. The first participant, in this case the farmer sells the cattle to the second participant, in this case the Botswana Meat Commission (BMC) which, in turn sells the processed beef to the European Union (EU). The BMC offers a price, S1(t), to the farmer for the cattle. The EU offers a price, S2(t), to the BMC. To estimate the parameters spot prices of beef-cattle from the BMC and the EU markets for years 1992 to 2...

Accelerating agricultural productivity to enhance economic growth in Botswana

Abstract: The need to diversify the economy so as to ensure sustainable economic growth has been of great concern. Accelerating productivity in agriculture is seen as one of the alternatives to support the diversification initiatives by the government and drive growth in Botswana. This study discusses the factors contributing to increased long term agricultural productivity and hence its subsequent impact on growth in the short. The study employs the vector error correction model and annual ...

Using “theory of change” to improve agricultural research: recent experience from Tanzania

Abstract: Demonstrating how agricultural research contributes to development outcomes is difficult but necessary given competing demands for scarce resources. This article summarises an adaptation of the “theory of change” approach and lessons derived from its application to improve the design and implementation of an agricultural research for development programme for greater impact. It was applied to Maziwa Zaidi, a programme that tested integrated interventions to catalyse the transfo...

Do farmers and the environment benefit from adopting integrated pest management practices? Evidence from Kenya.

Abstract: We estimate the impacts of a bundle of integrated pest management (IPM) practices on mango yield, mango net income, insecticide use, human health and the environment, using recent household survey data of mango growers in Kenya. We employ a multinomial endogenous switching treatment regression model with an ordered probit selection rule to establish counterfactual outcomes. Our results indicate that IPM-adopting farmers have higher mango yields and mango net income, and also use lo...

Reducing gender gaps in the awareness and uptake of drought-tolerant maize in Uganda: The role of education, extension services and social networks

Abstract: Cultivation of drought-tolerant (DT) maize seed reduces drought risk in sub-Saharan Africa. Data from eastern Uganda reveal gender gaps in awareness and adoption of DT maize. Among surveyed male household heads, 67.6 percent had awareness of DT maize varieties and 29.2 percent grew them. Corresponding figures for female household heads were 43.3 percent (awareness) and 5.3 percent (adoption) and those for wives in spousal couple households were 51.0 percent and 11.1 percent. Propen...

Do Farmers and the Environment Benefit from Adopting Integrated Pest Management Practices? Evidence from Kenya

A climate-adapted push-pull system effectively controls fall armyworm, Spodoptera frugiperda (J E Smith), in maize in East Africa

Abstract: Fall armyworm, Spodoptera frugiperda (J E Smith), an economically important pest native to tropical and subtropical America has recently invaded Africa, causing substantial damage to maize and other crops. We evaluated functionality of a companion cropping system, ‘climate-adapted push-pull’, developed for control of cereal stemborers in drier agro-ecologies, as an added tool for the management of fall armyworm. The technology comprises intercropping maize with drought-tolerant...

Women's empowerment in agriculture and agricultural productivity: Evidence from rural maize farmer households in western Kenya.

Abstract: This paper documents a positive relationship between maize productivity in western Kenya and women’s empowerment in agriculture, measured using indicators derived from the abbreviated version of the Women’s Empowerment in Agriculture Index. Applying a cross-sectional instrumental-variable regression method to a data set of 707 maize farm households from western Kenya, we find that women’s empowerment in agriculture significantly increases maize productivity. Although all indi...

Measuring farm and market level economic impacts of improved maize production technologies in Ethiopia: Evidence from panel data

Abstract: While it is often recognised that agricultural technology adoption decisions areintertwined and best characterised by multivariate models, typical approaches toexamining adoption and impacts of agricultural technology have focused on singletechnology adoption choice and ignored interdependence among technologies. Weexamine farm- and market-level impacts of multiple technology adoption choicesusing comprehensive household survey data collected in 2010/11 and 2012/13 inEthiopia. Econ...

Are individuals willing to pay for community-based eco-friendly malaria vector control strategies?

Abstract: This study was carried out to assess individuals’ willingness to pay (WTP) for UZIMAX, a novel plant-based biopesticide developed for malaria vector control. The biopesticide is estimated to kill up to 100% of Anopheles larvae within 48 h of application and poses no risks to human health and the environment. However, scaling-up of its adoption requires clear evidence of its acceptance by individuals in malaria-prone areas. We conducted Becker-DeGroot-Marschak (BDM) revealed prefe...

Women’s empowerment boosts the gains in dietary diversity from agricultural technology adoption in rural Kenya. F

Abstract: Using new survey data from rural Kenya, this paper assesses the moderating effect of women’s empowerment on the relationship between agricultural technology adoption and women’s dietary diversity. We use a multiple treatment endogenous switching regression framework to control for potential endogeneity of women’s empowerment and technology adoption. We find that women’s empowerment has a positive and significant effect on the women’s dietary diversity score regardless of ...

Potential adoption of integrated pest management strategy for suppression of mango fruit flies in East Africa: An ex ante and ex post analysis in Ethiopia and Kenya

Abstract: To sustain agricultural development in Africa, innovative strategies for addressing a myriad of biotic and abiotic constraints facing the agricultural systems must be established. One current biotic stress is the mango infesting fruit flies. In the effort to contain the widely spreading and damaging invasive species of tephritid fruit fly (Bactrocera dorsalis) (Hendel), an area-wide integrated pest management (IPM) program is being promoted in the horticultural sub-sector in sub-Sa...

Lepidopterans of economic importance in Cameroon: A systematic review

Adoption and Dis-Adoption of Sustainable Agriculture: A Case of Farmers’ Innovations and Integrated Fruit Fly Management in Kenya

Abstract: The invasive fruit fly Bactrocera dorsalis poses a major threat to the production and trade of mango in sub-Saharan Africa. Farmers devise different innovations to manage the pest in an attempt to minimize yield loss and production costs while maximizing revenues. Using survey data obtained from Embu County, Kenya, we analyzed farmers’ knowledge and perception as regards the invasive fruit fly, their innovations for the management of the pest, and the determinants of their adopti...

Role of multilateral development organizations, public and private investments in aquaculture subsector in Kenya

Abstract: Rapid population and economic growth, increased health benefits of aquatic food, and changes in lifestyles and preferences as a result of rapid urbanization and globalization are all contributing to the rapid growth of aquaculture production in Kenya. Despite significant investment efforts from the national and devolved governments as well as donors and international organizations, smallholder aquaculture production is yet to result in a significant increase in incomes and improved...
