'Brahmaputra edge lost to China' screamed the front page of one of India's leading newspapers on October 17, 2015. This was followed by outraged discussions over the impact of China's dam on downstream India. The author stated, “Under the doctrine of prior appropriation, a priority right falls on the first user of river waters. China now has that right”.
We beg to differ.
The sharing of water is not based on any one doctrine, but is governed by the Convention on the Law of the Non-navigational Uses of International Watercourses (1997), which are themselves based on the Helsinki Rules adopted by the International Law Association in August 1966. These state that 'Each basin State is entitled, within its territory, to a reasonable and equitable share in the beneficial uses of the waters of an international drainage basin'. The rules require that this 'reasonable and equitable share' be decided by weighing 11 factors which are to be 'considered together, and a conclusion reached on the basis of the whole'. The Law also has provisions for sharing of information, planning installations, protecting the environment, and advocates cooperation between basin states.
How do matters stand now?
A look at the schematic of the river tells us that while nearly half of the river flows through Tibet, its catchment there is a cold desert. So the river has comparatively lesser water flowing through it as it enters India. It is the one-third of the catchment area that is in India that receives 3000 mm of rain annually and significantly contributes to water in the Brahmaputra.
Indigenous peoples and environmentalists argue that dams are recent and for destructive uses, and so cannot be considered the primary users of the river. That distinction needs to be given to those who have, for centuries, been living with the river. Environmental flow requirements then need to be a critical aspect of an agreement to share river waters. The Law of the Non-navigational Uses of International Watercourses formulated in the 90s, does not explictly mention environmental flows, though it does caution protection of the environment.
A cursory examination of the factors influencing river sharing, based on data available with us from government, academic and civil sources, reveals that both nations have equal claims on the water. China has a larger proportion of the catchment area; India contributes more water. China has commissioned the first dam on the main stem; India has a larger population dependent on the river flows. Both countries have several tribes living in the basin which have strong cultural and livelihood affinities with the river.
So far we have seen that:
What happens if India feels threatened by China's use of the Brahmaputra?
For advice, we turned to a man whose knowledge of water conflicts is only exceeded by his tact. K J Joy, Director of SOPPECOM explained that India has three options if it is unhappy with the water-sharing status quo.
Joy maintains that transparency is the only possible route to avoid conflict. He illustrated this with the case of the Krishna, where a dispute between Maharashtra and Karnataka arose over who was responsible for damages due to flood releases. Ideally, he advocates managing the river basin as a cohesive unit. This has been done in the case of the Mekong River Commission, and might improve international relations in South Asia if repeated in the case of the Brahmaputra. At the least, he advocates transparency over reservoir management to avoid disputes over floods.
Will the tug-of-war between India and China finally rip apart the Brahmaputra?China has demonstrated its willingness to share flood related data with Bangladesh. Unfortunately, we do not have a good record in this matter. As Brahma Chellaney of the Centre for Policy Research , “The only reliable data (regarding the Brahmaputra) is from the United Nations. The Indian government doesn’t provide accurate data to mislead the public”.
However, before India asks for the same consideration, we need to be good neighbours too. The question raised by Gopal Krishna in his masterful plea for sanity 'Killing the Brahmaputra in installments' is worth keeping in mind. “While concerns about the Chinese government building dams on the Brahmaputra (unmindful of the views of the Tibetan people) are valid, wouldn't the Indian government's building dams on the Brahmaputra too affect Bangladesh down the river?”
