vulnerability of riverbank stability with the effects of frequent shocks and forestry's role
DESCRIPTION
Forestry and reducing vulnerability to riverbank stability. The effects of back to back shocks on riverbank structure.TRANSCRIPT
RISK & OPPORTUNITY FOR
RIVERBANK STABILITY FROM
NATURAL DISASTERS
WHO IS RESPONSIBLE FOR RIVERBANK STABILIZATION IN
GOVERNMENT?
FORESTRY DEPARTMENT
What was the future risk for riverbanks?Frequent, heavy rainfall causing flash floods
and soil erosionDeforestation especially by farmers along
the rivers
HURRICANE TOMAS 2010Damages to Forest sector:1. < 80 landslides majority of
which were on private lands
2. 80% of riverbanks were significantly eroded and left unstable
3. Water intakes compromised
4. Government changed hands and removed Forestry from Agriculture to Ministry of Sustainable Development
5. New management

WHAT FORESTRY DID AFTER TOMAS Sourced outside funds for landslide and riverbank rehabilitation - got
some from foreign organizations
Worked alongside players in the water sector to mitigate the impacts on the water resources of the country
Focused on implementing existing management plans including emergency management plans for forestry throughout the country
Needed and tried to source a consultancy for a new management plan
Conducted clearing of debris from rivers and began riverbank and landslide rehabilitation through project funding not by government funds
Engaged the schools, NGO’s, community groups, farmers and others in riverbank planting, and planting within landslides that occurred near communities, public road etc.
DID THE RIVERBANKS RECOVER IN TIME FOR THE NEXT SHOCK?

POST TROUGH STATUS Water was a main cause in the second shock Riverbank and soils were still recovering from the
first shock therefore suffered serious degradation Rivers were not de-silted enough and silt from
hurricane was deposited on either side of riverbank which compromised its stability
Not enough time to recover between shocks Reactive management continued to take place Government funds to Forestry was reduced Networking between certain sectors such as
Planning, Infrastructure, farmers not strengthened
PRESENT STATUS OF FORESTRY SECTOR Forestry not visible enough on the ground Management about to change hands
again Received funding to clear only 2 rivers Budget cuts within government Plenty of projects coming on stream but
with little or no capacity building within the organization
Not enough resources to devote to all the projects and to riverbank stabilization
LESSONS LEARNT Risk Management, before, during and after a shock is key in
reducing forest related vulnerabilities especially on riverbanks.
Riverbanks still not stabilized, due to private land ownership conflicts, not enough funds to clear all affected rivers of debris
Recommendations from consultancies need to be revised, implemented, monitored, evaluated and reported on in order to reduce vulnerability especially in the forest sector
Legal instruments need to reviewed, improved upon and enacted
Inter-sector networks needed strengthening, farmers needed to be educated
Need to build capacity within Forestry and the communities
OPPORTUNITIES FOR RIVERBANK STABILITY AND FORESTRY After every shock comes opportunity in the form of project funding,
training and capacity building of staff, educating farmers, etc.
Funds for stabilizing riverbanks by outside sources
Funds available for a consultancy towards a new management plan
Opportunity to carry out research on species vulnerability – to test what species on a riverbank can better withstand effects of hurricane, flood, etc. especially as climate change is now a main focal point in government
Opportunity to implement, assess and evaluate the effectiveness of the new management plan when completed.
New project opportunity to assist with sustainable livelihoods by researching slope vulnerability and rehabilitation in the worst hit farming areas, and by helping farmers select less vulnerable crops for these areas.
