Sorghum value chain analysis in semi-arid Zimbabwe

The role of extension in strengthening relationships among stakeholders along agricultural commodity value chains remains an important discussion point especially with orphan crops in semi-arid areas. The study used a participatory framework to analyse the sorghum value chain in the Mid Zambezi Valley of Zimbabwe. A sample comprising of 380 small scale farmers, proportionately selected from five major sorghum producing wards, was used. Six agrodealers, 15 traders, 10 retailers, three wholesalers, and two processors were also sampled. Inaddition, focus group discussions, informant interviews, questionnaires and reviews of records were conducted. Input supply systems for sorghum are weakly developed and production is stalled by inappropriate innovations including seed and fertilizer application. Marketing and processing channels are limited due to erratic supply and low producer prices. Demand for sorghum inputs can be created by engaging extension agents in helping farmers with realising the benefits of using improved sorghum seed varieties and fertilizer in sorghum production. This will smoothen the flow of sorghum products along strategic value chain nodes.Keywords: Sorghum, small scale farmers, value chain, extension networks, marketing margins, agribusines

Temporal rainfall trend analysis in different agro-ecological regions of southern Africa

Rainfall is a major driver of food production in rainfed smallholder farming systems. This study was conducted to assess linear trends in (i) different daily rainfall amounts (<5, 5–10, 11–20, 21–40 and >40 mm∙day-1), and (ii) monthly and seasonal rainfall amounts. Drought was determined using the rainfall variability index. Daily rainfall data were derived from 18 meteorological stations in southern Africa. Daily rainfall was dominated by <5 mm∙day-1 followed by 5–10 mm∙day -1. Three locations experienced increasing linear trends of <5 mm∙day-1 amounts and two others in sub-humid region had increases in the >40 mm day -1 category. Semi-arid location experienced increasing trends in <5 and 5–10 mm∙day-1 events. A significant linear trend in seasonal rainfall occurred at two locations with decreasing rainfall (1.24 and 3 mm∙season-1). A 3 mm∙season-1 decrease in seasonal rainfall was experienced under semi-arid conditions. There were no apparent linear trends in monthly and seasonal rainfall at 15 of the 18 locations studied. Drought frequencies varied with location and were 50% or higher during the November–March growing season. Rainfall trends were location and agro-ecology specific, but most of the locations studied did not experience significant changes between the 1900s and 2000s

Hidden Overburden of Female-Headed Households in Guar Bean Production: Zimbabwean Experience

The study was done on a guar bean-growing project in Makachi area, Zimbabwe. The study objectives were to determine ownership of resources, time spent on production and access to information by male-headed and female-headed households. Data collection and analysis were based on the FAO Gender Analysis Framework. Results showed that male-headed households had more ownership of resources and spent less time on production; access to information was equal; female-headed households allocated a greater proportion of their land to guar bean production and matched their male counterparts in the mean yield. While inter-household exchanges helped female-headed households access draft power and farming equipment, obligations associated with these exchanges were found to be a source of overburden to female-headed households

Factors affecting the choice of conservation agriculture practices adopted by smallholder cotton farmers in Zimbabwe

Conservation agriculture (CA) has been widely promoted in Zimbabwe as an antidote to non-viable agricultural production and continual land degradation. However, the adoption process had been quite slow and has not yet entered into the exponential uptake phase. This study aimed at identifying factors that influence the level of adoption of CA components. A cluster analysis from results of a household survey administered to 146 households in Muzvezve II, Kadoma District, Zimbabwe identified five dominant CA strategies (clusters) practiced by cotton growing farmers. A multinomial logit model revealed that the choice of CA components adopted is positively influenced by farmer’s age, formal education, access to extension services, labour, animal draught power availability and land size. The empirical results suggests that, to promote adoption of a complete package of CA policies that increase access to formal education and extension of CA should make strategic intervention through innovative methods of farmer to farmer extension services. Promotion of longer-term and effective CA can only be accomplished through targeting young educated farmers. It is of paramount importance as well to address the main factors leading to non-adoption and slow adoption such as labour and animal draught power availability

Does cooperative membership increase and accelerate agricultural technology adoption? Empirical evidence from Zambia

Open Access Article; Published online: 20 Jun 2020In developing countries, agricultural cooperatives are increasingly being used to promote improved agricultural technologies and alleviate food insecurity and poverty. However, little is known about the role of agricultural cooperatives in accelerating the adoption of improved agricultural technologies. Using a comprehensive balanced household panel and varietal data, this study applied the difference-in-difference model to identify factors affecting farmers’ decision to become cooperative members and the impact of cooperative membership on the adoption of improved maize, inorganic fertilizer and crop rotation. Furthermore, the study used the inverse probability weighted regression adjustment model to analyze the impact of cooperative membership on the speed of adoption of improved maize varieties. We found that cooperative membership increased the probability of technology adoption by 11–24 percentage points. Results further indicated that the average time to adoption was about 8 years, but it was shorter for cooperative members. The results showed that, on average, cooperative membership increased the speed of adoption of improved maize by 1.6–4.3 years. Generally, the results suggest the need for policies which promote farmer organizations such as cooperatives coupled with effective extension services for faster and greater adoption of improved technologies
