Smallholder Agroprocessors’ Willingness to Pay for Value-Added Solid-Waste Management Solutions

Abstract

The paper examined the willingness of smallholder cassava processors to pay for value-added solid wastes management solutions in Nigeria. We employed a multistage sampling procedure to obtain primary data from 403 cassava processors from the forest and Guinea savannah zones of Nigeria. Contingent valuation and logistic regression were used to determine the willingness of the processors to pay for improved waste management options and the factors influencing their decision on the type of waste management system adopted and willingness to pay for a value-added solid-waste management system option. Women constituted the largest population of smallholder cassava processors, and the processors generated a lot of solid waste (605–878 kg/processor/season). Waste was usually dumped (59.6%), given to others (58.1%), or sold in wet (27.8%) or dry (35.5%) forms. The factors influencing the processors’ decision on the type of waste management system to adopt included sex of processors, membership of an association, quantity of cassava processed and ownership structure. Whereas the processors were willing to pay for new training on improved waste management technologies, they were not willing to pay more than US$3. However, US$3 may be paid for training in mushroom production. It is expected that public expenditure on training to empower processors to use solid-waste conversion technologies for generating value-added products will lead to such social benefits as lower exposure to environmental toxins from the air, rivers and underground water, among others, and additional income for the smallholder processors. The output of the study can serve as the basis for developing usable and affordable solid-waste management systems for community cassava processing units in African countries involved in cassava production.

Isolation, Screening and Time Course Study of Amylase-producing Fungi from Garri Processing Environment

“…Sourcing amylases from microorganisms especially fungi are advantageous because the organism could easily be manipulated and bulk production of the enzyme is economical (Sunitha et al, 2012;Ogbonna et al, 2014). Nigeria has been adjudged to be among the largest producer of cassava in the world which accounts for 30 out of 84 million tonnes of cassava produced annually in Africa (Obueh and Odesiri-Eruteya, 2016;Omilani et al, 2019). Cassava processing in the country is mainly handled by small-scale farmers around their neighbourhood which poses environmental pollution due to inappropriate disposal of waste which percolate into the soil (Kolawole, 2014;Obueh and Odesiri-Eruteyan, 2016).…”

Cassava Waste Management and Biogas Generation Potential in Selected Local Government Areas in Ogun State, Nigeria

“…One of such crops is cassava, a starchy staple food crop which has the ability to resist drought and diseases. In 2012, the production of cassava worldwide was estimated at over 260 million tonnes, with Nigeria being the largest producer, contributing over 20% of the global production [1,2]. In Nigeria, cassava is mostly produced and processed by small-scale farmers at the family or village level.…”

“…As a result of this challenge, most rural cassava processors choose to dispose the cassava-processing wastes generated into the environment. These wastes have been identified to be toxic to the environment [2,4,6].…”

Assessment Of Environmental Degradation Due To Processing Of Cassava Into Garri Flakes

“…The knowledge gap on the impact of cassava waste to the environment by smallholders' farmers and also with ineffective waste management policies in Nigeria has made cassava waste management di cult (FAO, 2020). Studies have shown that the idea of sensitizing peasant farmers whose sole objective is to carter food and income for the family on effective cassava waste management is quite overwhelming and above their capability (Omalani, et al, 2019).…”
