Ecological footprinting and other standards
Published in David Thorpe, ‘One Planet’ Cities, 2019
The biocapacity supply is a measure of the pollution land can absorb and the services and resources it can provide to the population under investigation. The demand is a factor of this given population level and its consumption level, which is determined by its use of cropland, forests, grazing land and fishing grounds for providing resources and absorbing carbon dioxide from burning fossil fuels. The result can be an average of hectares per person (or nation), as if it were distributed equally between everyone (in the world or a given country) and as if all land were equal in what it could provide. A hectare is 2.47 acres or 10,000 square metres (m2) or 0.01 km2.

Süreyyabey Dam Lake is a rockfill dam located in the Northern part of Yozgat, Turkey (Figure 1). Çekerek stream, which is one of the most important tributaries of the Yeşilırmak River, and groundwater, are the main water sources of the dam. The surface area, total volume, and max depth of the dam lake are 41.34 km2, 1.18 km3, and ≅ 50 m, respectively. The water renewal time is ca. 0.47 year and average total phosphorus concentration was 0.074 mg/lt [21]. Moreover, it is serving irrigation water for nearly 42,000 ha. The height of the river bed is 77.5 m [22]. The basin of the dam is not densely populated, only Çekerek province (with a population of approximately 19.000) was located northern part of the dam. The basin is mainly dominated by agricultural and pasture areas. Fish-cage farming and fishing (trout, carp, mullet, and silverfish) are also common (Turkish Ministry of Agriculture and Forestry).

The proposed MLSA approach is implemented in Chadormalu iron ore mine of Iran. Chadormalu iron ore mine is located in the central desert of Iran, 180 km northeast of Yazd (Figure 8). Saghand village of Ardakan city, with a distance of 40 Km, is the nearest residential place to the mining area. The total mineable reserve of the mine is 320 Mt with an average grade of Fe 55.2% and a total stripping ratio of 2:1. The mineable reserve is running out (less than five years), and the average annual production in the last three years is approximately 15.1 Mt with an average stripping ratio of 3.9:1. The area is 39.2 km2. Chadormalu has a dry and cold climate in winter and hot in summer due to its geographical location in the desert. The amount of cold in winter nights sometimes reaches 16 °c below zero, and the temperature in summer rises to 45 °c. The annual average temperature of the region is 20.8 °c. The annual average wind speed is 52 Km/h, and the average yearly precipitation is 107 mm in the area. The wind speed has reached 90 Km/h, which causes sandstorms. The area’s vegetation is low, and only in some places, plants resistant to drought, heat, and salinity can grow [44].

The object of study is the transboundary river Yertis, the largest left tributary of the Ob. The river is 4.248 km long and flows through the territories of three countries: China (618 km), Kazakhstan (1.589 km), and Russia (2.041 km). The total area of the basin is 1.65 million km2. The watercourse originates on the western slopes of the Mongolian Altai, at an altitude of 2.500 m, where it is called the “Black Irtysh” (“Kara Yertis”). From China, under the name “Kara Yertis,” the river crosses the border with Kazakhstan, passes through the Zhaisan basin, and flows into drainage Lake Zhaisan (Zhaisan, Kazakhstan). Flowing from Lake Zhaisan, the Yertis river runs northwest across the West Siberian Plain, and the Yertis flows into the Ob near Khanty-Mansiysk (Russia).
