His administration is widely recognized as one of the most successful regional governments in Peru, with a focus on sustainable development, public investment, and conflict resolution.
His policies emphasized responsible use of natural resources and environmental protection, with particular attention to balancing the interests of local communities and mining companies.
One of the defining moments of his tenure was the negotiation of the Quellaveco mining project, where Vizcarra facilitated a dialogue that secured a social license, resolving community concerns about environmental impact.
In public service, he held positions such as dean of the College of Engineers of Moquegua (2008–2009) and board member of Empresa de Generación Eléctrica del Sur (2007–2010).
[5] Vizcarra's platform emphasized economic growth through the responsible use of Moquegua’s natural resources, particularly its agricultural and mineral sectors, while also advocating for greater transparency and efficiency in public administration.
This platform aimed to address socio-environmental concerns and secure a "social license" for the project, allowing the mining company to proceed with local community support.
[7] The dialogue table brought together a diverse group of stakeholders, including representatives from Moquegua’s civil society, local and regional authorities, Anglo American, and the national government.
Vizcarra played a key role in mediating between the different parties, identifying their interests and guiding the negotiations towards outcomes that benefited both the community and the mining company.
[5] The success of the Quellaveco dialogue process is largely attributed to the proactive involvement of the regional government, technical support, and the negotiation skills of civil society representatives.
[15] From the outset of his administration, Vizcarra prioritized direct engagement with citizens, stating that his policies were shaped through constant dialogue with those presenting proposals.
His administration was characterized by a balanced approach to development, supporting mining, commerce, and energy activities while also committing to the sustainable management of water resources.
"[16] His tenure saw improvements in social indicators, particularly in areas such as education and healthcare, while avoiding corruption scandals—a rarity in Peruvian regional governance, as noted by The Washington Post.
[11] His involvement with Moquegua earned him the opportunity to be chosen by Pedro Pablo Kuczynski, the presidential candidate of the Peruvians for Change party in the 2016 elections, as his running mate.
[16] His administration is credited with major improvements in regional education policies and the successful implementation of key infrastructure projects, including sanitation systems.
Historians and academics have highlighted these achievements as fundamental to the lasting impact of his government, which prioritized sustainable development and efficient use of regional resources.
