The character of Amman, Jordan, as the "City of Waters"—referring to the abundance of water flowing in its known stream—has faded away because of the municipal policy to cover the stream in the 1960s which gradually changed the ecological character. This paper traces and explores the impacts of stream-coverage policy on the city character, morphology and land use changes. The purpose is to understand how an engineered problem-solving policy changed physical and perceptive factors and affected the character of the city.

This article highlights the psychological dimension of social learning. Insights from psychology address the interrelated role of personal and group dynamics in social learning. This can provide a useful starting point for a rewarding use of social learning as an analytical tool in co-creative planning.

This paper presents five design prototypes for cool urban water environments developed in the 'Really cooling water bodies in cities' (REALCOOL) project. The REALCOOL prototypes address an urgent need: urban water bodies, such as ponds or canals, are often assumed to cool down their surroundings during days with heat stress, whereas recent research shows that this is not always the case and that urban water bodies may actually have warming effects too. There are, however, indications that shading, vaporising water, and proper ventilation can keep water bodies and their surroundings cooler.

Natural areas are essential for species conservation and outdoor recreation. Where conservation and recreational values are under threat, site managers need to take measures to protect them. Scientific knowledge and tools might help them to predict the outcomes of planned measures and create support amongst stakeholders. To be accepted by all stakeholders the knowledge and tools must possess three attributes credibility, salience and legitimacy.

This thesis investigates the communicative qualities of visual landscape design representations. The main subjects of inquiry were (1) visual design representations in their many forms and appearances; (2) the meanings that are attributed to, or derived from, those representations by designers, planners, and project stakeholders; (3) the participatory planning and design processes of the multifunctional flood defence landscape projects wherein those representations are used.

A new report developed by GIZ highlights success factors and 7 practical entry points for mainstreaming Ecosystem-based Adaptation (EbA) into policies and planning, based on 16 case studies from Mexico, Peru, South Africa, Philippines and Viet Nam in the following contexts:
1. National climate change policies (NDC, NAP)
2. National public investment allocation and project screening
3. Sectoral adaptation plans (water resources, protected areas, disaster risk reduction)
4. Land-use planning (spatial planning & landscape management)

In Sub-Saharan Africa, the popular perception of rangelands and their management is that these vast areas have major problems without solutions: the common narrative focuses on overgrazing, herds of undernourished livestock, erosion and desertification, drought, famine, and conflict.

However, evidence compiled and analysed in this book show that such a view of rangelands – as being unproductive and mismanaged systems – does not reflect reality. It needs reconsideration and revision.

Shaping an enabling environment for Land Degradation Neutrality (LDN) calls for integrated land use planning, inclusive and environmentally sound land access and governance, major reconfigurations of current institutional settings, financial backing, and ongoing dialogue between policy-makers, practitioners, and the scientific community.

The UNCCD-SPI technical report “Realising the Carbon Benefits of Sustainable Land Management Practices: Guidelines for Estimation of Soil Organic Carbon in the Context of Land Degradation” provides decision guidance for the estimation of soil organic carbon (SOC) in support of appropriate deployment of sustainable land management (SLM) technologies, in order to maintain or increase carbon in the soil and contribute to the achievement of land degradation neutrality (LDN).

Land degradation exacerbates the unique vulnerabilities of Small Island Developing States (SIDS) to environmental challenges, such as climate change, flash floods, soil erosion, lagoon siltation, coastal erosion and sea level rise, undermining their economic potential. Land Degradation Neutrality (LDN) contributes to achieving the Sustainable Development Goals (SDGs) in SIDS, preserving biodiversity and increasing resilience to climate change. Land degradation has a strong negative impact on climate-sensitive sectors like agriculture, water resources management and coastal zone management.

As global consumption and development rates continue to grow, there will be persistent stress placed on public goods, namely environmental amenities. Urban sprawl and development places pressure on forested areas, as they are often displaced or degraded in the name of economic development. This is problematic because environmental amenities are valued by the public, but traditional market analysis typically obscures the value of these goods and services that are not explicitly traded in a market setting.

Natural disasters are projected to increase in number and severity, in part due to climate change. At the same time a growing number of disaster risk reduction (DRR) and climate change adaptation measures are being implemented by governmental and non-governmental organizations, and substantial post-disaster donations are frequently pledged. At the same time there has been increasing demand for transparency and accountability, and thus evidence of those measures having a positive effect.
