“…A recently conducted GHG inventory analysis indicated that N fertilizers and lime spreading were key causes of GHG emissions (Colomb et al, 2014). Replacement of inorganic fertilizers with organic amendments in agriculture has been explored as a means of managing soil fertility in a more sustainable manner (Blazy et al, 2015;Sierra et al, 2016).…”

“…The use of systematic ploughing and monocropping, together with high rainfall intensity and the application of high rates of pesticide and inorganic fertilizers, are the principal factors causing soil degradation and pesticide and nitrate leaching (Cattan et al, 2009;Charlier et al, 2009). A recent GHG inventory carried out in French West Indies indicated that nitrogen (N) fertilizers and lime spreading ranked second after enteric fermentation among the most important causes of GHG emissions (Colomb et al, 2014). This situation is particularly critical insofar as climate change combined with intensive agricultural practises may lead to a decrease in soil organic matter content and then an increase in CO 2 emissions (Sierra et al, 2010).…”

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.
