However, to produce the inputs used by sector i, sector j also uses water.
This quantity of water required by sector j to produce the output used by sector i as input is called the indirect water use of sector i.
Finally, the production y i of sector i for its final demand corresponds to the quantity of water w yi d (m3) directly used by sector i to meet its demand.
For this purpose, recall the vector wy d = [w yi d ] in which each element is defined as the quantity of water directly used by sector i to meet its demand.
In order to estimate the indirect emissions in our study, we first define θ j ELE as the share of electricity used in sector j via: theta_{j}^{text{ELE}} = d_{j}^{text{ELE}} /q_{text{ELE}}where d j ELE is the amount of electricity used by sector j and q ELE is total supply of electricity.
By definition, direct emissions of CO2e are obtained via: q_{j}^{{{text{CO}}2D}} = sum, phi_{ej} q_{ej}where ɸ ej is the emissions coefficient of fossil fuel e in sector j and q ej is the amount of fossil fuel used by sector j.
The gross water used by different sectors, water use of Agriculture, hunting and forestry (sector 1), and the water use of industrial sectors in cubic metres for the year 2002 has been obtained from FAO AQUASTAT database.
Growth of these sectors will increases pressure on the seas, particularly on those areas that are densely used by traditional sectors such as fisheries and transport.
Sharon Lilly, ISA's educational goods and services director, hopes the program will be used by all sectors, including commercial, municipal and utility workers who are tasked with protecting the electric grid.
The scheme, called Performance Related Pay (PRP), is common in the private sector, although it's increasingly being used by public sector employers.
