Step 1: Impacts of the Preventive Grants of water in landscape planning

Step 2

In ​​Water Resources management, the Grant is the administrative act through which the public authority grants an applicant the right to use a water resource

The applicant can also request a Preventive Grant, through which a reservation is made for the flow withdrawal quota made in the planning phase of a project.

The preventive grant builds up the idea of ​​availability of water resources.

Step 3: The Grant is a crucial administrative step, representing the permission by public authorities for an applicant to access and utilize a water resource. Additionally, Preventive Grants play a significant role in shaping the discourse surrounding water availability. By reserving water withdrawal quotas during the planning phase of projects, they foster the perception of ample water resources. This perception influences development expectations and landscape planning by attracting activities with high water consumption potential.

According to the FAO, it is estimated that 60% of the water used in irrigation in the world is lost through evaporation or percolation. However, the UN in 2023 estimated that reducing 10% of the water used in agriculture would be enough to serve twice the world's population at the time. In Brazil, the largest demand for water is from the agriculture sector, that is, in irrigation, which is responsible for approximately 63% of the country's demand (REBOUÇAS, 2023).

Importance of integrated management of water resources to ensure water security.

Implementation of policies for water conservation and sustainable use.

Implementation of monitoring and assessment systems for water quality.

Adapting to climate change and its impacts on water resources involves implementing measures such as flood and drought management systems.

The integrated management of water resources security is a topic of utmost importance in times of increasing water scarcity and climate change. A multidisciplinary approach is crucial, involving not only governments but also local communities, non-governmental organizations, and the private sector. Effective policies for water conservation and sustainable use must be implemented, alongside measures for monitoring and controlling water quality. Additionally, it is essential to adapt to climate change and its impacts on water resources, ensuring the resilience of supply systems. The engagement of the population is equally important, through awareness campaigns and environmental education programs, aiming to promote responsible use and preservation of water resources for future generations.

·         The importance of Environmental Legislation and territorial planning regarding the use of land, open spaces and sustainable development practices in urban areas.

·         Implementation of laws and regulations to protect and conserve water resources in urban areas.

·         Development of rules to solve the increasing frequency and intensity of urban flooding and climate change, including the creation of green infrastructure and sustainable drainage systems.

The effective implementation of environmental legislation and territorial planning in urban areas is necessary to ensure the sustainable development of cities against of environmental and climate challenges. Thus, regulatory measures help control unplanned growth, promoting efficient land use and environmental preservation. Furthermore, by protecting and conserving water resources, these laws contribute to water security and quality of life in urban spaces. Therefore, with the increasing threats related to environmental impacts, such as floods, the adoption of policies that encourage the creation of green infrastructure and sustainable drainage systems becomes essential, not only to mitigate the impacts of floods but also to promote healthier and more resilient urban landscapes.
