Despite the increasing investment in sustainable development over the past decade, a systematic review of sustainable construction project financing is lacking. The objectives of this paper are to conduct a systematic review to examine the policies, practices, and research efforts in the area of sustainable construction project financing, and to explore the potential opportunities for the futur...
Commercial harvesting is recognized to induce adaptive responses of life-history traits in fish populations, in particular by shifting the age and size at maturation through directional selection. In addition to such evolution of a target stock, the corresponding fishery itself may adapt, in terms of fishing policy, technological progress, fleet dynamics, and adaptive harvest. The aim of this s...
Poor sanitation is one of the major hindrances to the global sustainable development goals. The Reinvent the Toilet Challenge of the Bill and Melinda Gates Foundation is set to develop affordable, next-generation sanitary systems that can ensure safe treatment and wide accessibility without compromise on sustainable use of natural resources and the environment. Energy recovery from human excret...
Historically, humans have created many sustainable practices, and among the most famous and successful sustainable practice is the rice–fish system in China. While previous studies have investigated eco-labeling food from various angles, consumer perception and preference of food produced from traditional sustainable practices (traditional sustainable food) remain unexplored. Taking the histori...
The emergence and dominance of parasitic replicators are among the major hurdles for the proliferation of primitive replicators. Compartmentalization of replicators is proposed to relieve the parasite dominance; however, it remains unclear under what conditions simple compartmentalization uncoupled with internal reaction secures the long-term survival of a population of primitive replicators ag...
This paper addresses a fundamental question in conservation ecology, which is the balance between rebuilding of a species’ population and exploiting them, by examining an appropriate sustainable management regulation for Pacific Bluefin tuna. The population of Pacific Bluefin tuna has been heavily depleted to just 2.6% of its historic unfished size by many years of overfishing. In order to rebu...
The aim of this study was to map soil erosion on the Mediterranean island of Cyprus. The G2 model, an empirical model for month-time step erosion assessments, was used. Soil losses in Cyprus were mapped at a 100 m cell size, while sediment yields at a sub-basin scale of 0.62 km2 mean size. The results indicated a mean annual erosion rate of 11.75 t ha−1 y−1, with October and November being the ...
in asia, food security and poverty alleviation depends on sustainable rice production. the study examined factors determining irrigated and rainfed rice farming sustainability in bangladesh. data for the study were collected through a farm households survey, covering 390 rice growers (sample size was determined by using the sloven’s formula), and also via observation, key informant interview, a...
This research assesses the environmental and economic benefits and costs of cleaner production projects formulated by smalland medium-sized enterprises (SMEs) participating in a sustainable supply program in Mexico. The program was designed as a public-private voluntary partnership to spur cleaner production dissemination in SMEs that are part of global supply chains. The study analyzes how pro...
Protected areas form a quintessential component of the global strategy to perpetuate tropical biodiversity within relatively undisturbed wildlands, but they are becoming increasingly isolated by rapid agricultural encroachment. Here we consider a network of 788 forest protected areas (PAs) in the world's largest tropical country to examine the degree to which they remain intact, and their respo...
