Tourism and water: from stakeholders to rights holders, and what tourism businesses need to do

Abstract: Water is a human right and it is essential to sustain life and livelihoods, as well as the health and happiness of tourists. This paper examines a destination with ample rain, but rapid and unchecked tourism development: Bali, Indonesia. The mismanagement of water resources means underground supplies are polluted and local people suffer from water scarcity. A multi-method approach with the various stakeholders was used to develop a stakeholder map that identifies duty bearers and rights holders. The government is the primary legal duty bearer to provide communities with water, but companies also have unique responsibilities. This paper examines why tourism businesses need to conduct human rights impact assessments. Taking due diligence for human rights can be seen as a business opportunity, leading to reduced operating costs and increased reputational strength. The benefits and challenges for business are explored.

The water‐energy‐climate nexus: Resources and policy outlook for aquifers in Mexico

Abstract: Three interlinked processes drive groundwater balances in diverse regions globally: (1) groundwater-irrigation intensification, (2) electrical energy supply for agriculture, and (3) climatic variability. Mexico's water-energy-climate nexus offers generic lessons because of its water scarcity and institutional reforms followed in other emerging economies. This paper analyzes data for 280 aquifers in Mexico, all registered water users, population projections, 2010–2100 precipitation and temperature projections for A1B and A2 emissions scenarios from 15 general circulation models, and 1999–2009 agricultural electricity use. Under A2 emissions, aquifers with negative balances will increase from 92 to 130 in number between 2010 and 2100, and the national groundwater deficit will increase by 21.3 km3. Under A2 and medium-variant population growth (which peaks midcentury), negative-balance aquifers will increase from 92 to 133, and the national groundwater deficit will increase by 22.4 km3. Agricultural power pricing offers a nexus-based policy tool to address aquifer depletion, an opportunity that was lost with the 2003 reduction in nighttime tariffs. Under A2, medium-variant population, and simulated 2% real annual increases in agricultural power tariffs, negative-balance aquifers will increase from 92 to 111, and the national groundwater deficit will increase by 17.5 km3 between 2010 and 2100. Regulatory and user-based groundwater management initiatives indicate growing awareness of aquifer depletion; however, the long-term outlook points to continued depletion. This raises the need to harness nexus-based policy options, i.e., increasing agricultural power tariffs, eliminating reduced nighttime tariffs, enforcing legislation linking groundwater extraction to power use, and limiting new power connections for groundwater wells.

Sustainability, Efficiency and Equitability of Water Consumption and Pollution in Latin America and the Caribbean

Abstract: This paper assesses the sustainability, efficiency and equity of water use in Latin America and the Caribbean (LAC) by means of a geographic Water Footprint Assessment (WFA). It aims to provide understanding of water use from both a production and consumption point of view. The study identifies priority basins and areas from the perspectives of blue water scarcity, water pollution and deforestation. Wheat, fodder crops and sugarcane are identified as priority products related to blue water scarcity. The domestic sector is the priority sector regarding water pollution from nitrogen. Soybean and pasture are priority products related to deforestation. We estimate that consumptive water use in crop production could be reduced by 37% and nitrogen-related water pollution by 44% if water footprints were reduced to certain specified benchmark levels. The average WF per consumer in the region is 28% larger than the global average and varies greatly, from 912 m3/year per capita in Nicaragua to 3468 m3/year in Bolivia. Ironically, the LAC region shows significant levels of undernourishment, although there is abundant water and food production in the region and substantial use of land and water for producing export crops like soybean.
