“…In most developing countries, agribusiness is an important component of the economy. Central to its sustainability are consumers' attitudes and market acceptance of the products [41,44]. One way of ensuring this, is by assessing the hypothetical WTP prior to production [41,45].…”

“…Where Y is the outcome variable for farmers' WTP having the bids 1 and 2 values and their responses (having bids as continuous values and the value of one if farmers are willing to pay for IBF in bid 1 or 2 and zero if the farmers are not willing to pay for IBF in bid 1 or 2), i indexes individual farmer's WTP, β 0 is the intercept, β i is the regression coefficient, X is a vector of explanatory variables that affect farmers' WTP, ε j is an error term, which assumes a normal distribution (mean = 0, variance = 1). Selection of explanatory variables used in this study (Table 1) were guided by a review of theoretical and empirical studies on the determinants of WTP for agricultural products [38,[41][42][43][44].…”

“…The results generated from this study strongly support the need for insect-based meal inclusion in feeds following standard regulation practices. However, it is worth noting that the successful introduction of a new product in the market depends on the product's marketplace acceptance by the target users, which ultimately will affect the WTP for the product [27,[44][45][46]. Therefore, we evaluated knowledge, attitudes, practices and WTP for IBF among poultry, fish and pig farmers in four counties in Kenya across different agro-ecological zones.…”

Smallholder farmers’ knowledge and willingness to pay for insect-based feeds in Kenya

Edible insects are increasingly being considered as sustainable alternatives to fish and soybean meals in animal feed because of their high nutritional quality and environmental benefits. However, successful introduction of a new product to the market depends on the target user's acceptance. Thus, evaluating the potential demand of insect-based feeds would provide relevant information for policy development. The present study assessed farmers' knowledge on edible insects as feed, their acceptance of integrating insect meals in animal feeds and willingness to pay (WTP) for insect-based feed (IBF) using a contingent valuation method. A household survey was conducted among 957 randomly selected farmers including: 409 poultry, 241 fish and 307 pig farmers in four counties in Kenya. Results of the study reveal that over 70 and 80% of poultry and fish farmers, respectively, are aware that insects can be used as a feed ingredient. In addition, over 60 and 75% of poultry and fish farmers, respectively, consider insects as a good component of feed. Poultry, pig and fish farmers interviewed accepted and showed willingness to pay for IBF. Regression analysis indicated that age, gender, education, marital status, distance to feed trader, awareness of insects as feed, attitude towards insects, acceptance of insect species, availability of agricultural inputs, use of commercial feeds, availability of training and market information had a significant influence on the WTP for IBF. Therefore, increased extension services to educate famers on the nutritional benefits of insect meals in animal feeds and existing market opportunities are expected to improve farmers' attitude towards utilization and consequently enhance WTP for IBF, which in return would significantly reduce the existing pressure on conventional fishmeal feed resources. Our findings provide the first insights into the market opportunities of including insect meals in the animal feed value chain in Kenya.

“…This means the respondents who have consciousness in environmental protection are willing to pay for environmental friendly products and may enhance critical evaluation of the relevance of better products than commercial ones. In the researches of [28] [29] [30] [2], the variable of awareness about environment have not been discussed yet. In the study on estimating urban households' WTP for upland forest restoration in Vietnam, however, [39] indicated that environmental awareness strongly affected to households' decision on purchasing for environmental protection service to protect upland forest.…”

“…Willingness to pay for a product is the amount of money which a consumer would be willing to pay for a higher level of environmental or commodity quality. According some previous studies [28] [29] [30] [2], socio-economic characteristic such as age, education, gender, household income and experience of using compost were used to determine the influence on farmer's willingness to pay (WTP) for compost made from organic and animal waste. However, awareness of environment and training factor seem to be not discussed yet in study of WTP for organic fertilizer product.…”

Determinants of Marketability for Organic Biomass Liquid Fertilizer from Human Waste in Da Nang City, Vietnam

Recently, 90 tons of human waste per day are collected from private residences, offices, and public facilities in Da Nang City. Meanwhile, farmers in this region have to allocate 10% -20% of rice sales for purchasing chemical fertilizer. Therefore, it is essential to be adopted more inexpensive organic fertilizer. To deal with these problems, Japan International Cooperation Agency (JICA) has signed a contract with Da Nang city government about human waste treatment and production of organic biomass liquid fertilizer (OBLF) in 2015. The aims of this project are to promote the use of OBLF in farming and improve public awareness of environmental protection. 530 respondents were interviewed at Hoa Vang districts of Da Nang city, and data was analyzed by Contingent Valuation Method (CVM) under double bounded dichotomous choice approach. The results have revealed that 436 respondents (82%) agreed to use OBLF. The farmers' WTP depends on factors including household income, experience in using organic fertilizer, awareness of environment and training of organic fertilizer in the past. The estimated price for OBLF was 94,856 VND (4.0 USD)/ton. The cost that farmers paid for OBLF was lower than that of current available chemical fertilizers in Da Nang city. This proves that marketability seems to be existed for OBLF product in Da Nang city. From these findings, the government should have policies to support and subsidize the farmers to encourage them to use OBLF in a large scale of cultivation. Furthermore, establishment of a market to consume the organic products harvested from cultivated areas using OBLF is also recommended.

This research aimed to determine the effectiveness of several types of liquid organic fertilizer (LOF) derived from plant waste and the dose of P fertilizer on the growth and yield of upland rice on degraded acid soil. The treatments consisted of two factors. The first factor (A) was several types of LOF consisting of A1 (control), A2 (LOF containing isolates of P-solubilizing bacteria), A3 (LOF-banana waste), and A4 (A2+A3). The second factor (B) was fertilizer doses consisting of B1 (50% of the recommended dose of P fertilizer), B2 (75% of the recommended dose of P fertilizer), and B3 (100% of the recommended dose of P fertilizer). The treatment combinations were arranged in a factorial randomized block design with three replications. The research results showed that applying either LOF-banana waste or the mixture of LOF-banana waste and LOF-containing isolates of P-solubilizing bacteria improved plant height, the number of tillers, and N and P uptake by the plant. The rice grain yields among the treatments were not significantly different, but the highest rice grain yield (139.8 g/pot) was obtained at the treatment of the mixture of LOF-P isolate + LOF-banana waste (A2+A3 treatments). The 75% of the recommended dose of P fertilizer was not significantly different from 100% P fertilizer with LOF on growth and yield upland rice and nutrient uptake by the plant.
