Sustainable Development and Its Indicators
Sustainable development focuses on improving living conditions while maintaining ecological balance. It encompasses economic and environmental aspects, aiming to meet current needs without compromising future generations. Indicators like pressure, impact, and sustainability indicators help measure progress towards sustainability.

Sustainable Development Development is concerned with the enhancement of living conditions. Sustainable development is one of the many processes of development. Sustainable development model includes both economic and the ecological aspects of the resources. The creation of waste and investment on its management, investment on regeneration of natural capital, the use of exhaustible resources, species extinction, valuing welfare of future approach to development. One of the widely accepted definition of sustainable development is from the report of the World Commission on Environment and Development ( WCED) in 1987. According to which SD is development that meets the needs of future generations to meet their own needs. In other words, it is a situation in which economic welfare does not decrease over time. It can be presented as a path of development in which options of future generations are not compromised by the path compromised by the path taken by the present generation. It is developed that is ever-lasting. It contributes to the quality of through improvements in natural environments.
Indicators of sustainable development Sustainability refers to both ecological and economic attributes. With economic development and ecological dimensions invite several new indicators for discussion. In order to capture all aspects of ecological and environmental changes, three types of indicators can be suggested . These are pressure indicators, impact indicators and sustainable indicators. Pressure indicators refers to flow variables. They show the development overtime of amounts or levels of emissions, discharges, depositions, extractions and interventions originating from a set of economic activities. This indicators express the burden on stocks of environmental goods and resources. The environmental pressure originating from economic activities in a specific region does not necessarily have to affect the same region. Emissions may be exported and imported by the direction of the wind. Impact indicators reflect the impact of environmental pressure on the receptors, usually in a predetermined region. These indicators include transboundary pressures. They show the development over time of the stocks and qualities of environmental goods and resources.
Both pressure and impact indicators can be transformed into sustainability indicators by relating pressure or impact with predetermined reference values. These references try to indicate what is considered to be a sustainable level of extraction or sustainable quality level of an environmental good. The sustainability indicator refers not only to the quantity (for example irrigation and drinking water), but also to the quality of an environmental resource system, that is the diversity of species of flora and fauna. We can represent the three types of indicators with the help of the following illustrative table 1-
