This document discusses land degradation and human vulnerability in Anambra State, Nigeria. It finds that Anambra State has the highest concentration of degraded land in the country, with 65% of the nation's gully erosion sites. The degradation is caused by both natural factors like climate and geology as well as human activities like deforestation, farming practices, mining, and poor drainage systems. Over 40% of the state's land area is severely degraded by gullies, with additional land being moderately or mildly affected. The degradation has negatively impacted communities through displacement, property and life losses, farmland losses, and infrastructure destruction. It also discusses traditional methods for controlling erosion and how understanding land degradation can inform disaster risk reduction policy

Added value for the Post 2015 Framework for 5th International Disaster and Risk Conference IDRC 2014 ‘Integrative Risk Management - The role of science, technology & practice‘ • 24-28 August 2014 • Davos • Switzerland www.grforum.org Disaster Risk Reduction • How did your work support the implementation of the Hyogo Framework for Action: – Our work adds to the knowledge on ecological sensitive areas in Anambra State . – It seeks to enhance consideration for the integration of disaster risks associated with land degradation into policy development and implementation with a focus on disaster prevention, vulnerability reduction and building of resilience at the community level. – Adds to Science-Policy Interface. • From your perspective what are the main gaps, needs and further steps to be addressed in the Post 2015 Framework for Disaster Risk Reduction in – Research: There is need for data sharing and to provide support for technology/instrument use for disaster risk reduction/management research especially in the developing countries. – Education & Training: There is a major need for training and education to enhance capacities and capabilities and for building resilience. – Implementation & Practice: There is a need to integrate traditional knowledge in implementing disaster risk reduction. Community-based networks need to be enhanced on building resilient communities. Women could be a force in resilience building as they play a major role in natural resources management especially at the local level. – Policy: There is an urgent need to encourage and reinforce a science-policy interface, which should be futuristic.
