=== Impact === Impact refers to how changes in the state of the system affect human well-being. It is often measured in terms of damages to the environment or human health, like migration, poverty, and increased vulnerability to diseases, but can also be identified and quantified without any positive or negative connotation, by simply indicating a change in the environmental parameters. Impact can be ecologic (e.g.: reduction of wetlands, biodiversity loss), socio-economic (e.g.: reduced tourism), or a combination of both. Its definition may vary depending on the discipline and methodology applied. For instance, it refers to the effect on living beings and non-living domains of ecosystems in biosciences (e.g.: modifications in the chemical composition of air or water), whereas it is associated with the effects on human systems related to changes in the environmental functions in socio-economic sciences (e.g.: physical and mental health).
=== Response === Response refers to actions taken to correct the problems of the previous stages, by adjusting the drivers, reducing the pressure on the system, bringing the system back to its initial state, and mitigating the impacts. It can be associated uniquely with policy action, or to different levels of the society, including groups and/or individuals from the private, government or non-governmental sectors. Responses are mostly designed and/or implemented as political actions of protection, mitigation, conservation, or promotion. A mix of effective top-down political action and bottom-up social awareness can also be developed as responses, such as eco-communities or improved waste recycling rates.
== Criticisms and Limitations == Despite the adaptability of the framework, it has faced several criticisms. One of the main goals of the framework is to provide environmental managers, scientists of various disciplines, and stakeholders with a common forum and language to identify, analyze and assess environmental problems and consequences. However, several notable authors have mentioned that it lacks a well-defined set of categories, which undermines the comparability between studies, even if they are similar. For instance, climate change can be considered as a natural driver, but is primarily caused by greenhouse gases (GHGs) produced by human activities, which may be categorized under "pressure". A wastewater treatment plant is considered a response while dealing with water pollution, but a pressure when effluent runoff leading to eutrophication is taken into account. This ambivalence of variables associated with the framework has been criticized as a lack of good communication between researchers and between stakeholders and policymakers. Another criticism is the misguiding simplicity of the framework, which ignores the complex synergy between the categories. For instance, an impact can be caused by various different state conditions and responses to other impacts, which is not addressed by DPSIR. Some authors also argue that the framework is flawed as it does not clearly illustrate the cause-effect linkage for environmental problems. The reasons behind these contextual differences seem to be differences in opinions, characteristics of specific case studies, misunderstanding of the concepts and inadequate knowledge of the system under consideration. DPSIR was initially proposed as a conceptual framework rather than a practical guidance, by global organizations. This means that at a local level, analyses using the framework can cause some significant problems. DPSIR does not encourage the examination of locally specific attributes for individual decisions, which when aggregated, could have potentially large impacts on sustainability. For instance, a farmer who chooses a particular way of livelihood may not create any consequential alterations on the system, but the aggregation of farmers making similar choices will have a measurable and tangible effect. Any efforts to evaluate sustainability without considering local knowledge could lead to misrepresentations of local situations, misunderstandings of what works in particular areas and even project failure. While there is no explicit hierarchy of authority in the DPSIR framework, the power difference between "developers" and the "developing" could be perceived as the contributor to the lack of focus on local, informal responses at the scale of drivers and pressures, thus compromising the validity of any analysis conducted using it. The "developers" refer to the Non-Governmental Organizations (NGOs), State mechanisms and other international organizations with the privilege to access various resources and power to use knowledge to change the world, and the "developing" refers to local communities. According to this criticism, the latter is less capable of responding to environmental problems than the former. This undermines valuable indigenous knowledge about various components of the framework in a particular region, since the inclusion of the knowledge is almost exclusively left at the discretion of the "developers". Another limitation of the framework is the exclusion of social and economic developments on the environment, particularly for future scenarios. Furthermore, DPSIR does not explicitly prioritize responses and fails to determine the effectiveness of each response individually, when working with complex systems. This has been one of the most criticized drawbacks of the framework, since it fails to capture the dynamic nature of real-world problems, which cannot be expressed by simple causal relations.
