The Aga Khan Development Network (AKDN) consists of a constellation of development agencies set up to bring the necessary resources and expertise to bear on a given area. Each agency is meant to interact with, and reinforce, the others. In Pakistan’s Northern Areas, for example, the activities of the Aga Khan Rural Development Programme (AKRSP) are coordinated with those of other AKDN agencies. While AKRSP built thousands of small infrastructure projects, installed hundreds of micro-hydroelectric plants, planted tens of millions of trees, reclaimed hundreds of hectares of degraded land and mobilised 4,000 community organisations, Aga Khan Health Services complemented these activities by setting up health services. Aga Khan Education Services set up schools and literacy programmes. Aga Khan University in Karachi provided education to many bright students who eventually returned to serve their communities as doctors, nurses and teachers. The Aga Khan Agency for Habitat created seismic-resistant designs for housing and community centres, set up water and sanitation projects and created over 70 low-cost housing improvements, and  provided disaster response and mitigation training. The Aga Khan Fund for Economic Development set up three hotels in the region – economic engines that provide jobs, set service standards and stimulate economic activity through local sourcing. The Aga Khan Agency for Microfinance administered thousands of new microfinance loans and pioneered micro-insurance for the poor. The Aga Khan Trust for Culture restored dozens of historic houses, monuments, landmark buildings and public spaces.
