Ex-ante agronomic and economic assessment of cropping systems under smallholder farming: The case of conservation agriculture in mountainous humid tropics (Northern Vietnam)
type: Dataset
description: Further agricultural intensification is expected to meet the on-going demographic transition and changes in consumption habits. There is therefore a need to identify contexts, options and conditions for intensive but sustainable land uses to develop. This question is of particular importance under contexts of smallholder farming and pressure on natural resources, such as in Asian humid tropics, where conservation agriculture (CA) is considered by several authors a leeway for sustainable intensification of agriculture. Within this context, our work aimed at preliminary assess to which extent CA fits the needs and constraints of smallholder farmers in a mountainous region where the high level of pressure on natural resources adds-up to a high poverty rate. We firstly implemented a diagnosis of sustainability gaps associated with the regional diversity of agricultural systems. To do so, we applied an original methodological approach combining diverse classification tools to maize based agricultural systems on sloping land. We identified 5 farm types and 7 maize cropping systems types, strongly contrasted in terms of management practices, performances and sustainability issues. The local diversity in maize cropping systems resulted from multi-scale interactions between territory-related factors, farm/farmer characteristics and field biophysical conditions. Within the context of our study, territory-related factors were of prevailing importance over plot biophysical conditions and farm/farmer related characteristics to drive diversity of cropping systems. Increasing economic profitability and agronomic productivity were compatible goals. However, tradeoffs were detected between economic profitability and mining of soil fertility. We subsequently investigated to which extent data collected at demonstration sites under project management can be used to determine whether CA has chance to become more productive and profitable over a 2-year period. Within the context of our s…
