In a less-favored area such as the Sahel, promoting sustainable management, breeding, and conservation of forestry resources would result in improvements for agroforestry systems and food security. A contingent ranking exercise allowed us to estimate the preferences and the values given by the rural population to the attributes that would be comprised in a conservation program. The resulting preferred program is farmer-managed natural regeneration (FMNR) based on the species Adansonia digitata (baobab), with plantation, stone bunds, or tassa, and selected or bred seeds. The proposed actions to improve the tree density and the seed quality were highly valued by the respondents. Nevertheless, no clear differences were found between tassa and stone bunds, or FMNR and plantation. The main effects of the program, according to the surveyed population, include an increase in crop production and soil conservation, and higher income from tree products. This study allowed us to identify the program that would provide the greatest well-being for farmers, since it would allow them to simultaneously improve both the production of their crops and the production of the woody food species. It was shown that farmers were particularly willing to contribute to a program based on baobab, mainly because its products are used for food in the home and can be sold in markets. In this sense, the yield and production of the system would be improved by increasing the number of baobab trees. Farmers would contribute to this production system and would be willing to invest sustainable effort in the long term. The conservation and breeding program can be directed at conserving and propagating the genetic resources of A. digitata in an initial phase, selecting trees with good production, growth, and adaptation characteristics.

尼日尔农民对森林粮食资源保护和育种计划的偏爱

在萨赫勒地区等不利的地区，促进林业资源的可持续管理，育种和保护将改善农林业系统和粮食安全。偶然的排序练习使我们能够估计农村人口对保护计划所包含的属性的偏好和价值。产生的首选程序是基于指状树种Adansonia digitata的农民管理的自然更新（FMNR）猴面包树（猴面包树），带有人工林，石堤或塔萨草，并精选或育成种子。受访者高度评价拟议的提高树木密度和种子质量的措施。然而，在塔萨和石堤之间，FMNR和人工林之间没有发现明显的差异。根据接受调查的人口，该计划的主要效果包括作物产量和土壤保护的增加以及树木产品的收入增加。这项研究使我们能够确定将为农民提供最大福利的计划，因为它将使他们能够同时提高农作物的产量和木质食品种类的产量。结果表明，农民特别愿意为基于猴面包树的计划做出贡献，主要是因为其产品用于家庭食品，并且可以在市场上出售。从这个意义上讲，通过增加猴面包树的数量，可以提高系统的产量和产量。农民将为这一生产系统做出贡献，并愿意长期投资可持续的努力。保护和育种计划可针对保存和繁殖遗传资源的遗传资源。指头草在初始阶段，选择具有良好生产，生长和适应性特征的树木。
