摘要：Intensifying inland valley systems will require the promotion of high value commodity chain system involving rice and vegetable with increased productivity and low per unit cost of production and natural resources. The objective aim to identify the current production systems assesses their constraints and analyzes the profitability of best bet rice and vegetable cropping systems under different levels of input use and access to market. A total of 235 producers selected in Benin and Mali according to input use and access to product market. The value chain approach used to analyze the performance associated with productivity. The results show that four main chain stakeholders operate in the inland valley: producers, processors, trader and consumers. This study specifically focuses on producers and major constraints reported by this group are attacks of the insects and birds, the poor access to products markets and the unavailability of key inputs (seeds, pesticides, small equipment,) in both countries. Other constraints are high costs of transport, post-harvest losses and poor conservation of fresh vegetables and tubers. The most profitable systems in the inland valley are the ones based on rice and vegetable (Gboma: Solanum sp) using improved seeds, follow-up of the system containing rice and `'gboma'' using improved varieties of rice like NERICA associated with chemical fertilizers and herbicides. Rice associated with improved varieties of potato and mineral fertilizers is more profitable in Mali. Rice as sole crop is not profitable in both countries. Women are more involved in the sole cropping of rice in Mali.
