In conclusion, this collection of papers shows that, just as delta environments are continually remade through the interplay of human intervention and environmental forces (more so than most other environments because of the dynamic nature of riverine erosion and deposition and the interface between land and sea), so too are livelihoods of delta dwellers continually adapting to the effects of similar sets of forces. The three deltas considered here were perceived by colonial administrations as "food bowls" that would generate wealth in British India (the Ganges-Brahmaputra-Meghna Delta) and Burma (the Ayeyarwady Delta), and for French colonial interests in Indo-China (the Mekong Delta). Delta regions in South and Southeast Asia have historically been key sites of trade, exchange and wealth-creation. What remains difficult to answer is the question of how future delta economies and residents' livelihoods will change, particularly for the resource-poor, should the social-ecological delta systems cross tipping points and reach a point of collapse (Renaud I et al i ., 2014).
