Faecal Sludge

Many sub-Saharan African towns currently face a “faecal sludge crisis”, because large amounts of faecal sludge from unsewered toilets (pit latrines, septic tanks etc.) are dumped into the environment. This causes public health problems and environmental degradation. The objective of this research was to investigate how faecal sludge management (FSM) can be made an integrated part of a sustainable ecological sanitation (ecosan) approach, with an emphasis on financial sustainability. Kumasi, a city in Ghana, West Africa, with 1.48 million inhabitants was chosen as a case study. Our research shows that the FSM of the city can be independent of donors’ financial support and thus financially sustainable if the potential revenue in both households and farmers is realised. This potential revenue was evaluated by (i) analysing the relevant functional groups and their relationships, (ii) a Capacity-to-Pay approach for households whereby they would spend up to 0.5% of their income on the toilet pit/septic tank emptying service (including a cross-subsidy approach), and (iii) on the farmers’ Willingness-To-Pay for compost (treated faecal sludge) based on a price of US$ 1.4 per 50 kg bag of compost. This additional revenue, which should be allocated to the System Manager (Kumasi Metropolitan Assembly) in the proposed financial scheme, was estimated to be US$ 57,000 per month from households and US$ 18,000 per month from farmers (based on 6300 m3/month of faecal sludge collected in Kumasi and a simplified financial analysis of the system).

Opportunities exist for adoption of precision agriculture technologies in all parts of the world. The form of precision agriculture may vary from region to region depending on technologies available, knowledge levels and mindsets. The current review examined research articles in the English language on precision agriculture practices for increased productivity among smallholder farmers in Sub-Saharan Africa. A total of 7715 articles were retrieved and after screening 128 were reviewed. The results indicate that a number of precision agriculture technologies have been tested under SSA conditions and show promising results. The most promising precision agriculture technologies identified were the use of soil and plant sensors for nutrient and water management, as well as use of satellite imagery, GIS and crop-soil simulation models for site-specific management. These technologies have been shown to be crucial in attainment of appropriate management strategies in terms of efficiency and effectiveness of resource use in SSA. These technologies are important in supporting sustainable agricultural development. Most of these technologies are, however, at the experimental stage, with only South Africa having applied them mainly in large-scale commercial farms. It is concluded that increased precision in input and management practices among SSA smallholder farmers can significantly improve productivity even without extra use of inputs.

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 adoption and dis-adoption decisions of recently developed and promoted integrated pest management (IPM) technologies for suppression of the pest. The results show that farmers consider fruit flies as a major threat to mango production (99%) and primarily depend on pesticides (90%) for the management of the pest. Some farmers (35%) however use indigenous methods to manage the pest. Though farmers possess good knowledge of different IPM strategies, uptake is relatively low. The regression estimates show that continued use of IPM is positively associated with the gender and education of the household head, size of a mango orchard, knowledge on mango pests, training, contact with an extension officer, and use of at least one non-pesticide practice for fruit fly management, while IPM dis-adoption was negatively correlated with the size of the mango orchard, practice score and use of indigenous innovations for fruit fly management. We recommend enhancing farmer′s knowledge through increased access to training programs and extension services for enhanced adoption of sustainable management practices for B. dorsalis.
