A research study was conducted to assess the management status and rangeland condition of three typical alpaca production systems in Pasco region: Communal Cooperatives (CC), Communal Farms (CF) and Livestock Associations (LA). The study used rangeland inventories, an analysis of producers’ perceptions about status, management and improvements needs of rangelands, in addition a proposal for spatial optimization of rangeland improvement strategies with Geographic Information Systems. Results showed that LA and CF had lands of lower quality than CC since they are located in hilly topography areas with high stoniness. These qualities affected reaction level and time of response to the application of improvement strategies. CC had rangelands of good condition (63 points) with positive trend, CF and LA had rangelands of regular condition (49.34 and 43.01 points) with negative to neutral trend. CC had a carrying capacity of 1.8 Al.U/ha/yr and positive forage balance (0.3 Al.U/ha/yr), while CF and LA had carrying capacity of 1.0 and 0.9 Al.U/ha/yr and negative forage balance (-0.3 and 1.5 Al.U/ha/yr, respectively), which revealed that organization and management levels, and economies of scale play a key role in alpaca production. Results suggest the necessity to adjust current rangeland management practices. Lack of water and irrigation infrastructure, rangeland overgrazing, and small grazeable land areas were the main difficulties that affect alpaca production. Meanwhile priorities of rangeland improvements were fencing of fields, establishment of irrigation systems, and technical training. Rangeland improvement strategies common to production systems and appropriate to characteristic of vegetation, lands and physiography were deferred rotation grazing system and management of water sources. However, the application of these strategies and others such as seeding of clover, fertilization, control of undesirable plants, cultivated pastures, need the development of sustainable rangeland management plans that include economic feasibility analysis and technical training programs.
