ARCOS Network: A Sustainable Mountain Development Hub for Africa

The African continent is endowed with mountains of high productivity, biodiversity, endemism, and cultural diversity. African mountain ecosystems play an important role in economic development, poverty alleviation, and environmental protection. However, climate change and extreme events, as well as human activities, alter the capacity of mountains to provide such services to millions of Africans who depend on them. Since the creation in 1995 of the Albertine Rift Conservation Society (ARCOS), mountains have been at the core of its programs, and collaboration among stakeholders is a key aspect of its search for sustainable solutions to threats affecting African mountains.


The mountain focus of the ARCOS Network
The Albertine Rift Conservation Society (ARCOS) is a nongovernmental organization (NGO) established in 1995 that originally focused on the rich mountain ecosystems of the Albertine Rift region but has now expanded its area of operation to cover all African mountains. ARCOS is implementing a global mountains program (Sustainable Mountain Development for Global Change or SMD4GC) in Africa. As a sustainable mountain development (SMD) hub for Africa, ARCOS partners with stakeholders, including NGOs, governments, community-based organizations, and the private sector, to enhance and maintain the health of African mountain ecosystems, which are key features in the economic development of African countries as well as the wellbeing of their people. As stipulated in its mission, ''to enhance biodiversity conservation and sustainable management of natural resources through the promotion of collaborative conservation action for nature and people,'' ARCOS believes in collaboration to tackle the issues facing key ecosystems in its geographic areas of interventionthe Albertine Rift, Africa Great Lakes region, and African mountains (ARCOS 2017). ARCOS's strategic areas are outlined in Figure 1.

African mountains and the SMD agenda for Africa
In 1999, ARCOS organized the first Albertine Rift Regional Mountain Forum. Since then, it has been bringing different stakeholders together to discuss and frame a shared mountain agenda for Africa. The current SMD efforts in Africa build on the existing stakeholders' efforts and focus on knowledge sharing to guide decision-making and dialogue to explore future challenges and opportunities for SMD with reference to global development agendas, especially Agenda 2030 and global agreements on climate change. ARCOS believes that SMD in Africa will be achieved through developing and strengthening policy and institutional arrangements and mechanisms for enhanced governance in mountain ecosystems, increasing investment in mountain development and conservation, enhancing mountain ecosystems and the participation of mountain communities, and implementing adaptation measures to address the impacts of climate change in mountain areas.

Meetings of mountain stakeholders in Africa and their policy outputs
In 2014, ARCOS and the East African Community organized the first African Regional Mountains Forum (http://events.arcosnetwork.org/), held in Arusha, Tanzania ( Figure 2). The forum called upon member states to develop and implement a shared mountain agenda and strategy for Africa.
In addition to the 2014 Arusha forum, there have been several other calls to action reiterating the need to strengthen mountain governance and to enhance cooperative action in mountain regions at various levels.  International 2015). All emphasized the need to promote and strengthen SMD, including the adoption of transboundary and regional frameworks for the sustainable management of African mountain ecosystems. Building on these mandates, the call for strengthened management and conservation of mountain ecosystems was reinforced at the 15th session of the African Ministerial Conference on the Environment in Cairo, Egypt, which called for the strengthening of the Africa Regional Mountains Forum as a center of knowledge, information exchange, and policy dialogue. ARCOS is the interim secretariat of this forum.
Later, countries in Africa started developing National Sustainable Mountain Development Strategies. The 2016 World Mountain Forum's outcome document called on governments, politicians, decision-makers, development and multilateral agencies, financing institutions, and mountain stakeholders to form policy, gather knowledge, and take action on reaching the targets of the Paris Agreement on climate change and the Sustainable Development Goals through specific attention to mountain regions; recognize upstream and downstream links, especially with regard to mountain ecosystem services; speak with one global mountain voice; and promote the inclusion of mountains in international processes and negotiations.

Bridging gaps in knowledge of African mountains
As knowledge is key to informed decisions (Figure 3), ARCOS developed an online platform, the ARCOS Biodiversity Information Management System (http://arbims. arcosnetwork.org/), to facilitate information sharing on issues pertaining to SMD. In the same framework, stakeholders also joined hands to enhance knowledge of Africa's mountains by collecting and packaging information. Those include, among others, ARCOS's

Conclusion
ARCOS and its partners are committed to finding sustainable solutions to key SMD challenges in Africa identified during the Africa Mountains Event that preceded the 2016 World Mountain Forum. Those challenges include limited investment in SMD and limited consideration of mountains in national development plans as well as the vulnerability of mountain communities to climate change. All those hinder the development of mountain areas as well as the development of a country as a whole. Everyone has a role to play in SMD, which is the factor that will determine our future. ARCOS encourages the ongoing SMD interventions and calls for support for the Africa Sustainable Mountain Development Fund, launched during the Africa Regional Mountain Forum.
Politicians, decision-makers, the media, and the public should join voices and advocate for recognition of mountains as a key context of sustainable development, especially for Africa. Water availability will be determined by how we care about the world's water towers-mountains (ARCOS Network et al 2013). Africans should also join forces to call for mountains to be given special attention in global financing mechanisms as relevant areas in which to tackle climate change and strategic places in which to eradicate poverty in Africa.
