在低收入和中等收入国家，旨在实现自然资源价值的农业创新技术和实践的吸收可能很少。将财政可行性评估与农民和环境评估结合起来，有助于了解创新吸收率低的某些方面。使用案例研究的可可豆荚壳（CPH）在印度尼西亚的价值，我们提供的见解（一）选择建模方法，以评估CPH价值的经济可行性和（ii）农艺试验评估的后果对土壤质量的转移CPH从其作为天然肥料的作用。经济可行性评估表明，农民要求的补偿水平高于收集或加工氯化石蜡的预期水平（一小部分农民将承担117英镑/吨氯化石蜡的所有加工活动）。农艺试验表明，CPH对土壤磷、钙、镁的维持作用较小，但对作物钾素的维持作用较大。CPH的去除将使碳和氮的部分平衡分别减少15.6%和19.6%。从目前的做法CPH转移应考虑对土壤质量的长期影响，特别是因为它可能会增加对矿物肥料的依赖。
The uptake of innovative technologies and practices in agriculture aimed at the valorisation of natural resources can be scant in Low and Middle Income Countries (LMICs). Integration of financial viability assessments with farmers and environmental evaluations can help to understand some aspects of the low uptakes of innovations. Using the case study of Cocoa Pod Husk (CPH) valorisation in Indonesia, we provide insights into (i) a choice modelling method to assess the economic viability of CPH valorisation and (ii) an agronomic trial assessing the consequences on soil quality of diverting CPH from its role as a natural fertilizer. The economic viability assessment suggested that farmers require higher levels of compensation than might be expected to collect or process CPH (a small proportion of farmers would undertake all processing activities for 117 GBP/t CPH). The agronomic trial concluded that CPH plays only a minor role in the maintenance of soil phosphorus, calcium and magnesium, but it plays an important role for crop potassium. CPH removal would reduce the partial balances for carbon and nitrogen by 15.6% and 19.6%, respectively. Diversion of CPH from current practices should consider the long-term effects on soil quality, especially because it might create increased reliance on mineral fertilizers.
