“…In sum, farmer groups provide an appropriate training and information framework for women. This is in line with those of Sotamenou (2012) and Yabi et al (2016) that farmer organisations improve the probability of adoption of agricultural innovations. They play a role of awareness and indisputable training (Sotamenou, 2012).…”

Mineral fertilisation by microdosing has been tested in Burkina Faso since 2000 to increase the agricultural productivity of small farmers. In order to identify the determinants of its adoption, data were collected from a random sample of 180 women and 440 men in the provinces of Zondoma and Kourittenga in Burkina Faso; where the innovation was disseminated. The results of the Logit model showed that the determinants of adoption varied according to gender and production area. In Kourittenga, warrantage (inventory credit system) system determined the choice by women, whereas that by men depended on warrantage and dissemination tools. In Zondoma, in addition to access to information on mineral fertilisation by microdosing on which the choices of each type of farmer were dependent, education level and belonging to a farmer organisation determined the choice of men and women, respectively. These results challenged policy decision makers to strengthen socioeconomic and institutional capacities for effective adoption of mineral fertilisation microdosing technique in order to sustainably improve the food situation of Sahelian small farmers.

“…As mentioned above, these concerns are key factors to reduce or stop the negative environmental impacts of agriculture in French West Indies. In order to support the transition to organic fertilization, several authors have also demonstrated the importance of institutional and social networks to limit the fixed and transaction costs of adoption (Espinosa-Goded et al, 2013;Mettepenningen et al, 2013;Sotamenou, 2012). The valuation of C sequestration could also be a means of improving the profitability of organic amendment (Aerstens et al, 2013;Antle et al, 2001;Bangsund and Leistritz, 2008).…”

Agri-environmental schemes (AESs) are the main public policy instrument used in Europe to encourage farmers to adopt environmentally-friendly farming practises. Some AESs designed in French West Indies to replace N fertilizers with composts to reduce nitrate pollution and enhance C sequestration have been unsuccessful because few farmers adopted them despite the subsidies offered for the provision of environmental benefits. To explain this low adoption rate, we assessed the agri-environmental and economic impacts of two AESs and compare them with the most widely-applied strategy based on inorganic N fertilizer (NFER), and with an organic strategy based on sewage sludge (SLUD), a free organic amendment. The first AES was proposed in 2007 (AES old) and only concerned with the use of composts. The second was proposed in 2014 (AES new) and combines the use of composts and inorganic N fertilizer at a rate 25% lower than NFER. The study was applied to water yam using a crop model to obtain agri-environmental indicators over a period of ten years, which were then used to calculate economic outputs for small and large farms. Although AES old increased C sequestration by 300% and reduced nitrate leaching by 80% compared to NFER, it also reduced yields (13%) and net income for farmers (30%). The subsidy offered by AES old did not compensate the loss of productivity, which explains its low rate of adoption. AES new and SLUD increased C sequestration (350% and 400%) and reduced nitrate leaching (45% and 34%), and maintained yields and net income after five years of implementation. Yields and net income during the first five years were 5-10% lower than under NFER. Although the land area concerned by SLUD is limited because of regulatory constraints, AES new could be a satisfactory policy instrument in French West Indies because it promotes environmental benefits and maintains economic income in the medium term for smallholder using family labour. The economic performance of AESs was lower for large farms; the adoption rate could be improved for these farmers through the implementation of mechanization to reduce labour costs. For both farm types, it may be necessary to increase subsidies during the first five years to offset yield losses during this period and the fixed and transition costs attached to adoption.
