Due to the scarcity of useable land in Hong Kong, it is a common practice to reclaim land from the sea. The reclaimed land usually undergoes a long period of settlement that may affect building structures and underground facilities such as water supply and sewage systems built on the land. Measurements of land settlement can provide valuable data for assessing the impacts of land settlement and...

A central challenge for sustainability is how to preserve forest ecosystems and the services that they provide us while enhancing food production. This challenge for developing countries confronts the force of economic globalization, which seeks cropland that is shrinking in availability and triggers deforestation. Four mechanisms-the displacement, rebound, cascade, and remittance effects-that ...

on-farm management practices with the aim of improving water use efficiency (wue) are among the practical ways of overcoming the water scarcity problem. this study aims to investigate ways of implementing agricultural water management in abarkouh region, yazd province, which mainly deals with problems such as water scarcity and salinity of soil and water resources. to this end, the resulting sc...

This study assessed how urban farmers survive land scarcity challenges in the midst of rapid urbanization a developing country such as Ghana. As becomes more pronounced areas, struggle to find place farm within space but numerous opportunities that come with farming city still inspires them spare lands and open spaces farm.

We study the interactions between technological change, resource scarcity and population dynamics in a Schumpeterian model with endogenous fertility. We find a steady state in which population is constant and determined by resource scarcity while income grows exponentially. If labor and resources are substitutes in production, income and fertility dynamics are stable and the steady state is the...

Previous research on warfare in a worldwide sample of societies by Ember and Ember (Journal of Conflict Resolution, 36, 242-262, 1992a) found a strong relationship between resource unpredictability (particularly food scarcity caused by natural disasters) in nonstate, nonpacified societies and overall warfare frequency. Focusing on eastern Africa, a region frequently plagued with subsistence unc...

In the Andean region of South America, understanding communities’ water perceptions is particularly important for water management as many rural communities must decide by themselves if and how they will protect their micro-watersheds and distribute their water. In this study we examine howWater User Associations in the Eastern Andes of Colombia perceive water scarcity and the relationship betw...

in recent decades, as a result of population growth, industrial developments, scarcity of sources, etc. more attention has been paid to spatial planning. spatial planning needs the consideration of different goals, scenarios, criterions and constraints, which leads us to the usage of spatial multi-criteria decision analysis (mcda) methods. the mail goal of this research is to develop a novel mo...
