There is a great potential to close the nutrient recycling loop, support a 'circular economy' and improve cost recovery within the waste sector and to create viable businesses via the conversion of waste to organic fertilizers. Successful commercialization of waste-based organic fertilizer businesses however largely depends on a sound market. We used a choice experiment to estimate farmers' willingness-to-pay (WTP) for faecal sludge and municipal solid waste-based (FSM) compost in Kampala, Uganda and considered three attributes-fortification, pelletization and certification. Our results reveal that farmers are willing to pay for FSM compost and place a higher value on a 'certified' compost product. They are willing to pay US $0.4 per kg above the current market price for a similar certified product, which is 67 times higher than the cost of providing the attribute. Farmers are willing to pay US $0.127 per kg for 'pelletized' FSM compost, which is lower (0.57 times) than the cost of providing the attribute. On the other hand, farmers require US $0.089 per kg as a compensation to use 'fortified' FSM compost. We suggest that future FSM compost businesses focus on a 'certified and pelletized' FSM product as this product type has the highest production cost-WTP differential and for which future businesses can capture the highest percentage of the consumer surplus. The demand for FSM compost indicates the benefits that can accrue to farmers, businesses and the environment from the recycling of organic waste for agriculture.

The study investigated factors influencing the choice of fish traders' marketing channel by fish trader and the determinants of their gross margins. A multistage sampling technique of 115 fish traders was used. Four key informants and two focus groups participated in the study. A Probit model was used to determine factors that influenced the choice of fish traders' marketing channel. Findings from the study revealed that volumes of fish traded per month, distance to market, membership to a fish marketing organization, payment mode, household size, presence of other sources of income were statistically significant in determining traders' choice of marketing channel. In addition, it was found that a formal trader on average sold 6.882 tons of fish whereas 2.095 tons of fish were sold by the informal trader per month. The study therefore recommends that Informal traders be clustered into a marketing organisation; through which they can be trained on business diversification, collective marketing, and group savings to ease access to credit. It is important to eliminate the challenges encouraging informal cross border fish trade by harmonizing regional fish standards, facilitating exchange and use of fishery trade information. Further, there is need to strengthen the data collection systems in order to have accurate estimates on the contribution of fish to trade and food security.

Despite the importance of cowpea in Uganda as a leading legume, its production and improvement have not received much attention over the last two decades. Data was obtained on prices of grains of cowpeas on a weekly basis from FIT Uganda between 2008 to 2011 in Soroti, Lira and Kampala. Data collected was analyzed using descriptive statistics, particularly, frequencies and the measures of central tendency. Several approaches were used to investigate the degree of cowpea market integration in Uganda: bivariate correlation coefficients, co-integration and Granger-Causality tests were used to account for the complex interactions of prices in different markets. Results from these tests show that cowpea markets as a whole are not integrated. This is not a surprising result since it can be linked to the general lack of market information. Prices in different markets are not equally responsive to changes in the supply of cowpeas. The results obtained will assist in subsequent cowpea variety improvement actions and decisions.
