Vetiver As Biopile Slope Stability
Climate change and land use mismanagement often when combined result in serious disasters, this is particularly so in high rainfall tropical locations. The most devastating being caused by tropical storms on steep lands resulting in land slides, flooding, infrastructure destruction, loss of life and serious reduction in economic output
unstable and highly erodible slopes that slip and end up as major sediment flows in downstream catchments. Vetiver is a tropical clump grass with origin in south India. It has the ability, when planted close together in a line, to create a near perfect barrier that filters out sediment, spreads rainwater, improves the shear strength of soil. The Vetiver System can provide very significant mitigation in the prevention and rehabilitation of such damage, including the stabilization of slip prone slopes, soil erosion control, levee and dike stabilization, river bank stabilization, road and highway stabilization, bridge abutment stabilization, and the stabilization of building sites. The Vetiver System's effectiveness has been proven time and time again including the protection and stabilization
Slope stability become critical factor for avoiding landslide in turn protecting injuries, asset and environmental. Vetiver planted to make deep pile for keeping the soil and stabilize the slope.
This is a unique value-added to the proposed work and to existing knowledge for mitigating the common landslide and best of scientific understanding and methods regarding climate change
To provide science-based solutions which accelerate successful protection of slope stabilization due to climate change at any highly erodible slopes that slip and end up as major sediment flows in downstream catchments. These solutions (e.g., practices, technologies, policies) will enhance the capacity land usage, other natural resource users and policymakers to better manage land, and the environment.
What are the major issues for land slide, rural livelihoods and slope stability in the context of climate change?
Land is sensitive to changes in climatic conditions, with outcomes affecting food security, livelihoods and economic prosperity. Climate change is a threat that, in the short term, will significantly affect the rural poor who are the most vulnerable given their limited resources and high exposure to risk. For example, poorly targeted and planned large irrigation schemes intended to respond to decreased rainfall in a given area could disrupt regional hydrological and biogeochemical cycles, leading to negative local and global repercussions.
Against this background, several key needs related to climate risk management for landslide can be identified:
The need to enhance the resilience of vulnerable farming systems and livelihoods in the
face of climate change.
The need to protect livelihoods from adverse climatic extreme events through effective
safety prevention on earth disaster particularly land slide
The need to continually adapt technology (e.g., vetiver usage ) to a lift slope stability
Without due caution, current and future policies in slope stability, land protection, natural resources and environment can contribute to the negative effects of climate change on the community.
What major challenges does a research program need to be addressed ?
The IPCC Climate Change Assessment (2007) stresses that most of the research on agriculture and climate change has focused on the impacts of climate change on crop production in different regions.
Climate variability and climate change impacts and options for mitigation and adaptation areembedded in a highly dynamic policy environment. Climate change adaptation and mitigation strategies require supporting policy and institutional interventions at many different scales, ranging from crop and on-farm management to the community, national, regional, and global levels. Policy and institutional analysis must be part and parcel of support, reversing adverse and reinforcing positive impacts from climate change and climate mitigation and adaptation strategies. Specific analyses on policy and institutional aspects are therefore needed as an integral part of the impact and response research.
The need to continually adapt technology (e.g., agrobiodiversity, water use) and policy
(e.g., land use planning, insurance schemes) to a changing environmental baseline.
The need to anticipate land slide from erodible slopes that slip and end up as major sediment
flows in downstream catchments

Features include crown, head scarp, basal surface of rupture, transverse cracks, transverse ridges and radial cracks. All created in the downward and outward movement
Vetiver has a wide range of applications, and the common domesticated cultivars used around the world are non-invasive. The plant will virtually grow anywhere except where the winter temperatures result in summers are too mild. Thus it main areas of growth are in the tropics and semi tropics, Mediterranean climates, and in arid regions (when there is available supplementary water). Its primary uses are for soil and water conservation, soil fertility enhancement, bio-engineering, phytoremediation of contaminated land and water, disaster mitigation, and a bioproduct supply for forage, fuel, handicrafts, and perfumary. It also sequesters significant quantities of atmospheric carbon.
Targeting and priority-setting will be achieved by:
The Program will also seek to understand local knowledge, perceptions of climate risk and current adaptive strategies of rural communities, and how such knowledge and strategies are compatible with research-based recommendations; and conversely, understanding influences of local cultures and traditions on the uptake of new adaptation strategies. It will thereby help people cope better with current climate variability and shocks. This is an essential pre-requisite in building their livelihood resilience and hence their adaptive capacity
for future climate change.
Timelines and deliverables
Research activities and outputs are designed to set clear goals, milestones and review points to ensure measurable progress and integration between tasks and findings. Engagement, collaboration and partnership building will be the subject of focused laboratory, workshops and field activities; and will also be subjected to review relative to specific milestones. Outside Expertise will be involved in determining method, to deliver appropriate monitoring, evaluation and synthesis.
it will strengthen the capacity of scientists to address the particular challenges of climate change in slope stability; it will enhance the capacity of key stakeholders to continue to adapt to the impacts of climate change:
Follow the timeline schedule from sponsor but basically the research will take minimum 1 year calendar
