Virtual Environmental and Humanitarian Adviser Tool – (VEHA Tool) is a tool
to easily integrate environmental considerations in humanitarian response. Field Implementation guidances are useful for the design and execution of humanitarian activities in the field.
Sudden or progressive change in the environment adversely affects the lives or living conditions of people who may have been displaced from their origin. When environmental degradation occurs or sudden onset hazards impact vulnerable areas, people may be forced to move and relocate to areas that then require new infrastructure. The new infrastructure should be built to be resilient and strong enough to endure the impact of future natural hazards.
Excluded people hold the least power to influence decision-making whilst decisions regarding construction are usually made with people who hold significant relative power. Normally excluded people should be consulted regarding potential environmental impacts and regarding their personal needs and dependencies on the local environment.
Loss of biodiversity and ecosystems
Natural Resource Depletion
Air, water, soil pollution, damage to ecosystems, blockage of drainage channels and watercourses; increase in waste dumping and/or waste going to landfill; depletion of natural resources and increase in greenhouse gas emissions.
Poor management of construction waste leads to significant environmental impacts.
Construction waste can cause air, water, and soil pollution; damage to ecosystems; blockage of drainage channels and watercourses; increase in waste dumping and/or waste going to landfill; depletion of natural resources and increase in greenhouse gas emissions.
Construction waste can pose physical and chemical hazards to humans and the natural environment. It can also be a host for disease vectors.
Create a waste management plan.
Ensure procurement of sustainable high-quality durable materials.
Waste separation, reuse, and recycling.
Create a plan for the safe and environmentally sustainable management of construction waste. This should include careful planning of material quantities to reduce waste; improved construction techniques that reduce the creation of waste; careful planning to re-use construction waste and debris from the crisis; procurement of good quality materials from sustainable renewable sources; waste separation and re-use and recycling materials.
Potential construction waste should be preidentified, and an appropriate disposal management plan per waste stream should be developed. Appropriate disposal sites should be identified in consultation with local authorities and prohibit dumping in waterways and wetlands.
K4D share lessons here: https://opendocs.ids.ac.uk/opendocs/bitstream/handle/20.500.12413/15893/923_Urban_flood_management_in_Africa.pdf? on flood risks, including the risk of flood from blocked drainage channels.
Floods damage infrastructure, homes, and livelihoods and also spread disease. Remediation can include covering drains and drain entry points to prevent debris from entering, as well as planting trees and shrubs to slow water flow, and water retention ponds or infiltration pits to reduce flooding.
WASH procurement agreements ensure sustainable sourcing of construction materials
Construction methods are changed to reduce waste creation and increase the reuse of leftover materials
Construction waste is reduced, separated, and recycled
Prevention of environmental damage
Mitigation of environmental damage
Time to assess causes and develop plans to reduce waste from procurement, construction processes, and waste management.
