1) There is a need to build capacity in constructed wetland management in Malaysia, including developing guidelines, educating stakeholders, and establishing monitoring protocols.
2) Constructed wetlands can treat wastewater, improve water quality, and provide habitat, but their design and maintenance requires expertise across multiple disciplines.
3) Capacity building efforts should provide training, strengthen organizations, and facilitate technology transfer to ensure constructed wetlands' long-term sustainable use.

Traditional knowledge in climate smart agriculturejayanta thokdar
Traditional knowledge is unique to a given culture or society which established over time. It is techniques or practices which is well knitted with customs, traditions and beliefs in rural life. Mainly rural people or tribal are main custodian of this traditional knowledge. The traditional knowledge or practices are found to be socially desirable, economically affordable, sustainable, and involve minimum risk to rural farmers and producers. This knowledge is evolved over time periods so it offers a climate resiliency. The knowledge is also based on their belief and customs, so it is location specific and acceptable. As modern science or approaches are not well suited to many rural or remote locations, there integration between these two knowledge may provide better understanding and result. Modern approaches are resource exploitable however it is widely believed that traditional practices try to conserve resources. It provides basis for problem solving strategies for local communities. CSA identifies agricultural strategies suitable to local conditions for sustainable food production under climate change scenario.

Simulation and validation of turbulent gas flow in a cyclone using CaelusApplied CCM Pty Ltd
Cyclones play a dominant role in the industrial separation of dilute particles from an incoming gas flow. The complex swirling flow in cyclones provides significant challenges for turbulence modelling in CFD. This paper presents a single phase transient solver developed using the Caelus library. The solver predictions using k-ω SST with and without curvature corrections, Reynolds Stress Model (LRR) and Large Eddy Simulation (Smagorinsky and coherent structure) turbulence models are compared against laser velocity measurements to investigate the level of accuracy afforded by each turbulence model. The k-ω SST model without any curvature corrections produced the poorest predictions of the flow field, whilst the coherent structure LES was found to be in excellent agreement with the experimental measurements.

A wetland is a land area that is saturated with water , either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem .
The primary factor that distinguishes wetlands from other
land forms or water bodies is the characteristic vegetation of aquatic plants , adapted to the unique hydric soil.

What is Environmental Engineering?
Environmental engineering takes from broad scientific topics like chemistry, biology, ecology, geology, hydraulics, hydrology, microbiology, and mathematics to create solutions that will protect the health of living organisms and improve the quality of the environment.
Environmental engineering is the application of scientific & engineering principles to improve and maintain the environment to
protect human health, protect nature's beneficial ecosystems,
and improve environmental-related enhancement of the quality of human life.
Environmental engineers study the effect of technological advances on the environment, addressing local and worldwide environmental issues such as acid rain, global warming, ozone depletion, water pollution and air pollution from automobile exhausts and industrial sources.
Aligning Watershed and Habitat Protection for Conservation Success in the Rac...rshimoda2014
Lindsay Gardner - Southeast Aquatics Resources Partnershp
Nothing is more important than water for human health and the health of our fish and wildlife resources. Clean water and abundant habitat are critical to functional aquatic ecosystems with healthy populations of fish and wildlife. Successful aquatic resource conservation at the watershed level requires a multipronged approach working with local communities to restore ecologically impacted or impaired streams and put land use/habitat protections in place. The collaborative efforts of the Southeast Watershed Forum (SEWF), Southeast Aquatic Resources Partnership (SARP), The Nature Conservancy (TNC), the Environmental Protection Agency (EPA), U.S. Fish & Wildlife Service (USFWS), Georgia Wildlife Resources Division (GWRD), and other key partners in the Raccoon Creek area of the Etowah River Watershed, Georgia, an EPA priority watershed, provide a positive example of this holistic approach to watershed management. Building on the conservation planning, land protection and restoration efforts by TNC on Raccoon Creek, this partnership is successfully working with Paulding County stakeholders to identify conservation priorities and align watershed and conservation planning with county land use planning to ensure long-term benefits for prime habitat and water quality. This work encourages conservation-oriented growth practices and habitat protections to benefit fish and wildlife, like the Cherokee darter, and supports the regional habitat objectives of the SARP-directed Southeast Aquatic Habitat Plan, addressing threats to aquatic resources and key habitat protections. An outstanding example of how on-the-ground restoration of aquatic resources at the local level, the project also addresses national conservation priorities and demonstrates how through community-supported land use quality growth planning it is possible to develop a strategy and stewardship ethic to maintain these resources for generations to come.
