The Asian Highlands, the vast mountainous area from Pakistan to China including the Hindu-Kush Himalaya and Tibetan Plateau, have considerable global importance; they are the source of most of the major rivers of Asia, which sustain billions of downstream dwellers, are part of four Global Biodiversity Hotspots, and support rich cultural diversity. However, climate warming in the Himalaya-Tibetan Plateau has been greater than two times the global average, and regional climate appears to be shifting with potential to trigger large-scale ecosystem regime shifts ('landscape traps'). A host of other drivers-urbanization/infrastructure development, land-use/agricultural practices, upstream/downstream water management and ongoing nation-state security conflicts-interact with climate signals to produce complex changes across ecological and social systems. In response, highlands people are evolving hybrid forms of adaptive capacity where 'bottom-up' behaviors are mixing with 'top-down' state and market policies. To increase ecosystem and livelihood resilience to future change, there is a need to link upstream and downstream conservation action with local climate adaptation. While the key problem is that institutional and government capacity for coordination is low, we present four general strategies to move forward: application of cross-sector coordinated planning, strategic integration of science-based conservation with developing local-level hybrid knowledge, recognition of the critical role of governance in support of change, and increased emphasis on environmental security. We discuss these strategies for each driver of change in the region.

INTRODUCTION
Into the 21st century as human alteration of Earth's lands and waters continues to expand, less developed regions such as the Asian Highlands are increasingly subject to ecological and social * Correspondence to: j.c. transformation. The highlands, the vast area of mountains and high plateaus above 1000 m stretching from Pakistan to China and including the Hindu-Kush Himalaya and Tibetan Plateau, have considerable global importance; they are the source of most of the major rivers of Asia (Figure 1). This 'Water Tower of Asia' directly sustains approximately 150 million people and has impacts on the lives of several billion downstream dwellers.1 The Asian Highlands also host parts of four Global Biodiversity Hotspots: the Himalayas, Indo-Burma, Mountains of Southwest China, and Mountains of Central Asia. The region has some of the highest species endemism in the world. In addition, the highlands' great variation in topography and elevation gradients supports rich cultural diversity This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made. expressed in multiple langu...
