Integrated water resources management (IWRM) has been defined by the Global Water Partnership (GWP) as "a process which promotes the coordinated development and management of water, land and related resources, in order to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems". [1]
IWRM is a paradigm that emerged at international conferences in the late 1900s and early 2000s, although participatory water management institutions have existed for centuries. [2] Discussions on a holistic way of managing water resources began already in the 1950s leading up to the 1977 United Nations Water Conference. [3] The development of IWRM was particularly recommended in the final statement of the ministers at the International Conference on Water and the Environment in 1992, known as the Dublin Statement. This concept aims to promote changes in practices which are considered fundamental to improved water resource management. IWRM was a topic of the second World Water Forum, which was attended by a more varied group of stakeholders than the preceding conferences and contributed to the creation of the GWP. [2]
In the International Water Association definition, IWRM rests upon three principles that together act as the overall framework: [4]
In 2002, the development of IWRM was discussed at the World Summit on Sustainable Development held in Johannesburg, which aimed to encourage the implementation of IWRM at a global level. [5] The third World Water Forum recommended IWRM and discussed information sharing, stakeholder participation, and gender and class dynamics. [2]
IWRM practices depend on context; at the operational level, the challenge is to translate the agreed principles into concrete action.
Operationally, IWRM approaches involve applying knowledge from various disciplines as well as the insights from diverse stakeholders to devise and implement efficient, equitable and sustainable solutions to water and development problems. As such, IWRM is a comprehensive, participatory planning and implementation tool for managing and developing water resources in a way that balances social and economic needs, and that ensures the protection of ecosystems for future generations. In addition, in light of contributing the achievement of Sustainable Development goals (SDGs), [6] IWRM has been evolving into more sustainable approach as it considers the Nexus approach, which is a cross-sectoral water resource management. The Nexus approach is based on the recognition that "water, energy and food are closely linked through global and local water, carbon and energy cycles or chains."
Water’s many different uses — for agriculture, for healthy ecosystems, for people and livelihoods — demands coordinated action. An IWRM approach is consequently cross-sectoral, aiming to be an open, flexible process, and bringing all stakeholders to the table to set policy and make sound, balanced decisions in response to specific water challenges faced.
An IWRM approach focuses on three basics and aims at avoiding a fragmented approach of water resources management by considering the following aspects:
Some of the cross-cutting conditions that are also important to consider when implementing IWRM are:
IWRM should be viewed as a process rather than a one-shot approach - one that is long-term and iterative rather than linear in nature. As a process which seeks to shift water development and management systems from their currently unsustainable forms, IWRM has no fixed beginnings or endings.
Furthermore, there is not one correct administrative model. The art of IWRM lies in selecting, adjusting and applying the right mix of these tools for a given situation.
Environmental resource management is the management of the interaction and impact of human societies on the environment. It is not, as the phrase might suggest, the management of the environment itself. Environmental resources management aims to ensure that ecosystem services are protected and maintained for future human generations, and also maintain ecosystem integrity through considering ethical, economic, and scientific (ecological) variables. Environmental resource management tries to identify factors affected by conflicts that rise between meeting needs and protecting resources. It is thus linked to environmental protection, sustainability, integrated landscape management, natural resource management, fisheries management, forest management, and wildlife management, and others.
The International Water Management Institute (IWMI) is a non-profit international water management research organisation under the CGIAR with its headquarters in Colombo, Sri Lanka, and offices across Africa and Asia. Research at the Institute focuses on improving how water and land resources are managed, with the aim of underpinning food security and reducing poverty while safeguarding the environment.
Integrated coastal zone management (ICZM), integrated coastal management (ICM), or integrated coastal planning is a coastal management process for the management of the coast using an integrated approach, regarding all aspects of the coastal zone, including geographical and political boundaries, in an attempt to achieve sustainability. This concept was born in 1992 during the Earth Summit of Rio de Janeiro. The specifics regarding ICZM is set out in the proceedings of the summit within Agenda 21, Chapter 17.
Sustainable forest management (SFM) is the management of forests according to the principles of sustainable development. Sustainable forest management has to keep the balance between three main pillars: ecological, economic and socio-cultural. Sustainable forestry can seem contradicting to some individuals as the act of logging trees is not sustainable. However, the goal of sustainable forestry is to allow for a balance to be found between ethical forestry and maintaining biodiversity through the means of maintaining natural patterns of disturbance and regeneration. Successfully achieving sustainable forest management will provide integrated benefits to all, ranging from safeguarding local livelihoods to protecting biodiversity and ecosystems provided by forests, reducing rural poverty and mitigating some of the effects of climate change. Forest conservation is essential to stop climate change.
Landscape-scale conservation is a holistic approach to landscape management, aiming to reconcile the competing objectives of nature conservation and economic activities across a given landscape. Landscape-scale conservation may sometimes be attempted because of climate change. It can be seen as an alternative to site based conservation.
Natural resource management (NRM) is the management of natural resources such as land, water, soil, plants and animals, with a particular focus on how management affects the quality of life for both present and future generations (stewardship).
The Global Water Partnership (GWP) is an international network created to foster an integrated approach to water resources management (IWRM) and provide practical advice for sustainably managing water resources. It operates as a network, open to all organisations, including government institutions, agencies of the United Nations, bi- and multi-lateral development banks, professional associations, research institutions, non-governmental organisations, and the private sector.
Marine spatial planning (MSP) is a process that brings together multiple users of the ocean – including energy, industry, government, conservation and recreation – to make informed and coordinated decisions about how to use marine resources sustainably. MSP generally uses maps to create a more comprehensive picture of a marine area – identifying where and how an ocean area is being used and what natural resources and habitat exist. It is similar to land-use planning, but for marine waters.
Ecosystem management is an approach to natural resource management that aims to ensure the long-term sustainability and persistence of an ecosystems function and services while meeting socioeconomic, political, and cultural needs. Although indigenous communities have employed sustainable ecosystem management approaches for millennia, ecosystem management emerged formally as a concept in the 1990s from a growing appreciation of the complexity of ecosystems, as well as humans' reliance and influence on natural systems.
Integrated urban water management in Aracaju, the capital city of the Brazilian State of Sergipe (SSE) has been and still is a challenging prospect. Home to half a million people, Aracaju is located in a tropical coastal zone within a semi-arid state and receives below average rainfall of 1,200 mm/year where average rainfall in Latin America is higher at 1,556 mm/yr. Most of the residents do have access to the potable water supply and non-revenue water losses are nearly 50%.
The UNESCO World Water Assessment Programme was founded in 2000 in response to a call from the UN Commission on Sustainable Development (CSD) to produce a UN system-wide periodic global overview of the status, use and management of freshwater resources. To meet this challenge, WWAP coordinates the work of 31 UN-Water members and international partners, under the umbrella mechanism of UN-Water, in the production of the World Water Development Report (WWDR). The WWDR is the UN flagship report on water issues; it is a comprehensive review, released every year with a different focus on different strategic water issues, that gives an overall picture of the state, use and management of the world’s freshwater resources and aims to provide decision-makers with tools to formulate and implement sustainable water policies.
The Dublin Statement on Water and Sustainable Development, also known as the Dublin Principles, was a meeting of experts on water related problems that took place on 31 January 1992 at the International Conference on Water and the Environment (ICWE), Dublin, Ireland, organised on 26–31 January 1992.
Type II partnerships were developed at the Johannesburg World Summit on Sustainable Development in 2002. Arising in opposition to the state-centred eco-governmentality of previous approaches to sustainable development policy, the partnerships facilitate the inclusion of private and civil actors into the management of sustainable development. The partnerships are employed alongside traditional intergovernmental mechanisms in order to effectively implement the United Nations' Agenda 21 and Millennium Development Goals, particularly at sub-national level. Although widely acknowledged as one of the most innovative and effective developments in global environmental governance in recent years, the partnerships have faced criticism due to fears of a lack of accountability, and the risk that they may exacerbate inequalities of power between Northern and Southern states. Despite these reservations, there is a general consensus among state and non-governmental actors that Type II partnerships are a significantly progressive step in global environmental governance in general, and sustainable development discourse in particular.
Sustainable land management (SLM) refers to practices and technologies that aim to integrate the management of land, water, and other environmental resources to meet human needs while ensuring long-term sustainability, ecosystem services, biodiversity, and livelihoods. The term is used, for example, in regional planning and soil or environmental protection, as well as in property and estate management.
Ocean governance is the conduct of the policy, actions and affairs regarding the world's oceans. Within governance, it incorporates the influence of non-state actors, i.e. stakeholders, NGOs and so forth, therefore the state is not the only acting power in policy making. However, ocean governance is complex because much of the ocean is a commons that is not ‘owned’ by any single person or nation/state. There is a belief more strongly in the US than other countries that the “invisible hand” is the best method to determine ocean governance factors. These include factors such as what resources we consume, what price we should pay for them, and how we should use them. The underlying reasoning behind this is the market has to have the desire in order to promote environmental protection, however this is rarely the case. This term is referred to as a market failure. Market failures and government failures are the leading causes of ocean governance complications. As a result, humankind has tended to overexploit marine resources, by treating them as shared resources while not taking equal and collective responsibilities in caring for them.
Soil governance refers to the policies, strategies, and the processes of decision-making employed by nation states and local governments regarding the use of soil. Globally, governance of the soil has been limited to an agricultural perspective due to increased food insecurity from the most populated regions on earth. The Global Soil Partnership, GSP, was initiated by the Food and Agriculture Organization (FAO) and its members with the hope to improve governance of the limited soil resources of the planet in order to guarantee healthy and productive soils for a food-secure world, as well as support other essential ecosystem services.
The water, energy and food security nexus according to the Food And Agriculture Organisation of the United Nations (FAO), means that water security, energy security and food security are very much linked to one another, meaning that the actions in any one particular area often can have effects in one or both of the other areas.
The term Nature-based solutions (NBS) refers to the sustainable management and use of natural features and processes to tackle socio-environmental challenges. These challenges include issues such as climate change, water security, water pollution, food security, human health, biodiversity loss, and disaster risk management.
Ecosystem-based adaptation (EbA) encompasses a broad set of approaches to adapt to climate change. They all involve the management of ecosystems and their services to reduce the vulnerability of human communities to the impacts of climate change. The Convention on Biological Diversity defines EbA as "the use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people to adapt to the adverse effects of climate change".
Sustainable Development Goal 15 is about "Life on land." One of the 17 Sustainable Development Goals established by the United Nations in 2015, the official wording is: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss". The Goal has 12 targets to be achieved by 2030. Progress towards targets will be measured by 14 indicators.
