“…Furthermore, ref. 36 has extended this even further to include water as an endowment, used in both agricultural and other sectors. Finally, we have a data set in which we can derive the shares of labor, capital, land, water, and several other inputs in producing all commodities.…”

Human activities are threatening to push the Earth system beyond its planetary boundaries, risking catastrophic and irreversible global environmental change. Action is urgently needed, yet well-intentioned policies designed to reduce pressure on a single boundary can lead, through economic linkages, to aggravation of other pressures. In particular, the potential policy spillovers from an increase in the global carbon price onto other critical Earth system processes has received little attention to date. To this end, we explore the global environmental effects of pricing carbon, beyond its effect on carbon emissions. We find that the case for carbon pricing globally becomes even stronger in a multi-boundary world, since it can ameliorate many other planetary pressures. It does however exacerbate certain planetary pressures, largely by stimulating additional biofuel production. When carbon pricing is allied with a biofuel policy, however, it can alleviate all planetary pressures.

“…In another paper, Taheripour et al (2016) use the water-augmented GTAP database and the GTAP-BIO-W model to study the economy-wide impacts of improvements in Water Use Efficiency (WUE) in irrigation in South Asia. This paper argues that with no improvement in WUE, this region will face major water challenges in the future.…”

Water is an essential input in the production processes of all goods and services. However, most economic models ignore water as an essential factor of production. In contrast with other inputs, economic data do not reflect the role of water in the production processes of goods and services and its final value in the demand side. This makes it difficult to incorporate water in economic models, properly examine its role in economic activities, and study its interaction with other inputs in the production processes. Introducing water into an economy-wide database such as Global Trade Analysis Project (GTAP) Data Base which has been widely used by many economic modelers across the world could help them to extend their research agendas on the role and importance of water in economic activities. As the first step towards this direction we divided the crop sectors of the GTAP-Power Data

“…Additionally, amidst a changing climate, new energy and climate policies may be proposed to support bioenergy production as an alternative to conventional fossil-based methods, placing food and energy production in direct competition for land resources Gillingham et al, 2008;Johansson and Azar, 2007;Popp et al, 2014;Smyth et al, 2010;Timilsina et al, 2012;Winchester and Reilly, 2015;Wise et al, 2014). One way to accommodate a growing demand for both food and bioenergy is to intensify existing crop land by increasing crop yields through investments in irrigation technology (Beringer et al, 2011;Taheripour et al, 2016). However, to explore the potential impacts of intensification on food prices and bioenergy production, we need to understand the physical and cost constraints on irrigable land expansion.…”

We develop a framework to represent the production value and expansion potential of irrigated land within economy-wide models, providing integrated assessment capabilities for energy-land-water interactions. The scope to expand irrigated land is quantified through irrigable land supply curves for 126 water regions globally based on water availability and the annual costs of irrigation infrastructure. Upgrades in irrigation infrastructure include (1) increasing water storage, (2) improving conveyance efficiency, and (3) improving irrigation efficiency. The value of production on irrigated and rainfed cropland is computed at both a 5 arcminute by 5 arcminute level and for the 140 regions and eight crop sectors in Version 9 of the Global Trade Analysis Project (GTAP) Data Base using estimates of production quantities and prices from the year 2000. This work facilitates the representation of endogenous investment in irrigation infrastructure and allows for a more rigorous exploration of the regional and global impacts of water availability on land use, energy production, and economic activity.JEL codes: Q11, Q15, Q25
