“…Although Malaysia is considered a low-water-stress country based on the World Resource Institute Ranking [21], Johor, despite its good river system [22] centred around the Johor River, which provides 60% of its water supply [23], is known for water scarcity [24]. According to the National Water Resource study, demand for water in Johor has consistently increased, and this trend will continue [25]. This may not be unconnected to the increasing population, urbanisation, industrialisation and large-scale agricultural activities [26], increasing demands for water [27].…”

Changes in land-use–land-cover (LULC) affect the water balance of a region by influencing the water yield (WY) along with variations in rainfall and evapotranspiration (ET). Remote sensing satellite imagery offers a comprehensive spatiotemporal distribution of LULC to analyse changes in WY over a large area. Hence, this study mapped and analyse successive changes in LULC and WY between 2000 and 2015 in the Johor River Basin (JRB) by specifically comparing satellite-based and in-situ-derived WY and characterising changes in WY in relation to LULC change magnitudes within watersheds. The WY was calculated using the water balance equation, which determines the WY from the equilibrium of precipitation minus ET. The precipitation and ET information were derived from the Tropical Rainfall Measuring Mission (TRMM) and moderate-resolution imaging spectroradiometer (MODIS) satellite data, respectively. The LULC maps were extracted from Landsat-Enhanced Thematic Mapper Plus (ETM+) and Landsat Operational Land Imager (OLI). The results demonstrate a good agreement between satellite-based derived quantities and in situ measurements, with an average bias of ±20.04 mm and ±43 mm for precipitation and ET, respectively. LULC changes between 2000 and 2015 indicated an increase in agriculture land other than oil palm to 11.07%, reduction in forest to 32.15%, increase in oil palm to 11.88%, and increase in urban land to 9.82%, resulting in an increase of 15.76% WY. The finding can serve as a critical initiative for satellite-based WY and LULC changes to achieve targets 6.1 and 6.2 of the United Nations Sustainable Development Goal (UNSDG) 6.

“…'As late as 2013, observers were still considering Singapore a "captive market" for Malaysian chicken eggs, with over 94 per cent of fresh eggs found in Singapore's wet markets, supermarkets and restaurants coming mostly from Johor (the proportion has since come down, mostly due to a resurgence of local production in Singapore, but still remained above 75 per cent in 2016).' 8 The production-consumption compact between Singapore and offshore neighbours is in some ways an accident of history and politics -an international border separates a dense urban core from the adjacent landscape hinterland that supports it, however the need to import becomes far more problematic when basic resources are imported from long distances.…”

The Supertight refers to the small, intense, robust and hyper-condensed spaces that emerge as a by-product of extreme levels of urban density. These ideas were explored through a site-specific architectural installation and curated exhibition that was held in Melbourne in 2019 and drew on contributions from practitioners throughout Asia to explore the role of design in negotiating and expressing density in urban environments. The project explored the term ‘Tight’ as a positive and more nuanced approached to thinking about urban density. If the Supertight is focused on cities, its consequence is equally on the landscapes that support cities. While we as architects focus on the object of density, the centre of cities – their organisation, occupation and formal characteristics, we often overlook the vast hinterland that supports dense urban cores. Cities such as Singapore and Hong Kong, which were explored heavily through the exhibition and are in many ways models of the physical and social management of extreme density, are equally exemplars of cities that rely heavily on supply chains that stretch well beyond their borders. This paper will build upon discussions emerging from the Supertight exhibition and will critically reflect upon and document the relationship between dense urban cores and the broader networks that support their existence. While urban density and compact cities are generally understood to be more sustainable than sprawl, to what extent does the close settlement of cities result in an expansion of terrain and resources to support them? Do dense cities require more to enable their existence, and how does behaviour and patterns of consumption impact that potential for density to be sustainable? The paper will explore how productive landscapes that support dense cities be absorbed within dense urban cores, and what would need to shift to enable this.
