De tuinders van VAT-Ede (Vereniging Amateurtuinders) wilden een verkenning uitvoeren naar de mogelijkheden om het bestaande volkstuincomplex De Koekelt om te vormen tot een multifunctioneel tuinenpark. Het volkstuinencomplex De Koekelt biedt door haar ligging en grootte ongekende mogelijkheden om een multifunctioneel tuinenpark te realiseren.

Voor de Natuurbalans 2005 heeft het Milieu- en Natuurplanbureau analyses verricht van veranderingen in het ruimtegebruik en het effect daarvan op de kwaliteit van het landschap. Verstedelijking speelt daar een belangrijke rol in. Tevens neemt men verstening waar in het landelijk gebied: landbouwbedrijven krijgen een meer industrieel karakter met grote schuren en silo's

Volgens Timmermans is de emancipatie van het groen in de stad voltooid: groen is een integraal onderdeel van de stad geworden. De kracht van Alterra is verschoven naar het bij elkaar brengen van kennis bij ontwikkelingsprojecten; het ontwikkelen van nieuwe concepten en innovaties. Concepten van duurzame stedelijke ontwikkeling zijn op deze manier terug te vinden in voorbeelden als Waalsprong en IJpenburg

Text in Italian. English sum.: This study examines a number of cases in which the people of Ziguinchor, in the Casamance region of Senegal, have been in dispute with the public authorities over the question of access to land in urban areas. These conflicts, however, should not obscure the fact that the citizens of Ziguinchor and the representatives of the Senegalese State generally manage to reach a consensus on questions of urban land use.

The National Land Act of 1964, designed to unify legislation concerning land, formally abolished the various local systems of land law in Senegal. The implementation of the various urban land regulations and the efforts to restructure and regulate the spontaneous settlements which were started in Ziguinchor, the capital of the Casamance, in the 1970s resulted in a great number of urban land conflicts. This paper reviews Senegalese law relating to urban land.

La majorité de la population de Ziguinchor (Sénégal) appartient au groupe diola. Ce sont des 'autochtones' vis-à-vis des gens du nord, en particulier des Wolof, dont la présence paraît liée à l'action de l'État sénégalais et de son administration territoriale. Les pratiques locales sont ainsi dominées par une opposition entre des représentations foncières quasi villageoises des premiers occupants et les conceptions bureaucratiques mises en ouvre par les fonctionnaires de l'État.

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.

Propelled by rapid urbanization, city administrations in low-and middle-income countries face a raft of challenges to secure food and nutrition for its poor urban dwellers. Urban agriculture (UA) seems a viable intervention to address urban food insecurity, however, experience has shown that urban gardens do not expand at the expected rate. Tackling this issue requires a deeper understanding of the main constraints that block UA expansion. Benin is not an exception; the country witnesses a breathtaking growth of its main cities that is in synchronization with a mounting food insecurity.

In the effort to achieve the Sustainable Development Goals (SDGs) related to food, health, water, and climate, an increase in pressure on land is highly likely. To avoid further land degradation and promote land restoration, multifunctional use of land is needed within the boundaries of the soil-water system. In addition, awareness-raising, a change in stakeholders' attitudes, and a change in economics are essential. The attainment of a balance between the economy, society, and the biosphere calls for a holistic approach.

Countries in Southeast Asia have been developing quickly from a predominantly rural to predominantly urban society, leading to a rapid increase in urban land. This increase in urban land has mainly occurred in river deltas and floodplains, exposing humans and human assets to flood hazard. Here we present an assessment of current and future flood risk in five countries of mainland Southeast Asia, using a new modeling approach that accounts for differences in urban land systems.

Land use and land cover change is a critical factor of ecosystem services, while water yield plays a vital role in sustainable development. The impact of urban expansion on water yield has long been discussed, but water yield change resulting from cropland protection is seldom concerned. Therefore, this paper aims to investigate the impacts of cropland protection on water yield by comparing the water yield in two cropland protection scenarios (i.e., Strict Cropland Protection scenario and No Cropland Protection scenario).

A wide variety of settlement systems exist, ranging from small villages to large metropolises. However, spatial analyses are typically confined to the mere presence or absence of built-up land and the changes therein, while more subtle differences between various settlement systems are ignored. In this paper we study the spatial distribution of Chinese settlements in terms of their built-up land, cluster density and cluster size, as well as their changes between 1990 and 2010.
