Since the founding of Singapore in 1819, more than 95% of its estimated 590 square km of vegetation has been cleared. At first for short-term cash crops and later because of urbanization and industrialization. 61 of its original 91 bird species has been lost leading to many native forest plants not being able to reproduce because of loss of seed dispersal and pollination.
Health issues are associated with the entire process of waste management. Health issues can also arise indirectly or directly: directly through the handling of solid waste, and indirectly through the consumption of water, soil, and food. [2] Waste is produced by human activity, for example, the extraction and processing of raw materials. [3]
This report understands food loss and waste as the decrease in quantity or quality of food along the food supply chain. Empirically it considers food losses as occurring along the food supply chain from harvest/slaughter/catch up to, but not including, the retail level. Food waste, on the other hand, occurs at the retail and consumption level ...
Fecal sludge is defined very broadly as what accumulates in onsite sanitation technologies and specifically is not transported through a sewer.It is composed of human excreta, but also anything else that may go into an onsite containment technology, such as flushwater, cleansing materials and menstrual hygiene products, grey water (i.e. bathing or kitchen water, including fats, oils and grease ...
Together, the collection, transport, treatment and end use of fecal sludge constitute the "value chain" or "service chain" of fecal sludge management. Fecal sludge is defined very broadly as what accumulates in onsite sanitation systems (e.g. pit latrines, septic tanks and container-based solutions) and specifically is not transported through a ...
AVA helps to provide Singapore with an adequate and stable supply of food. It achieves this by diversifying the sources of supply to Singapore through efforts in the following areas: Approving new sources for importation of food by the private sector, Participating in trade missions to seek out new sources,
Subsequently, an experimental water reclamation treatment plant was built in 1974, but the operation was terminated after only one year due to costs and reliability issues. [2] In 1998, the Public Utilities Board (PUB) and the Ministry of the Environment and Water Resources (MEWR) initiated the Singapore Water Reclamation Study (NEWater Study). [3]
The water resources of Singapore are especially precious given the small amount of densely settled land. Singapore receives an average of 2,400 mm of rainfall annually, well above the global average of 1,050 mm. The constraint is the limited land area to catch and store the rainfall, and the absence of natural aquifers and lakes. [11]
