The Sustainable Development Goals have emphasized that SLM is at the core of global environmental and development issues. SLM simultaneously addresses food security, climate change adaptation and mitigation, disaster risk reduction, biodiversity, and water conflict resolution. However the value and importance of scaling-up SLM is not yet sufficiently acknowledged by policymakers or the broad public, thus hindering the allocation of adequate resources to combating land degradation.
Although information and data on land degradation and SLM are increasing worldwide, there is a lack of evidence and awareness on the specific impacts of SLM onsite and offsite. Evidence-based examples highlighted in each case study help to target these gaps by raising awareness and increasing knowledge about various interlinked impacts in areas onsite, where SLM is directly implemented (upstream), and offsite areas (downstream).
WOCAT (The World Overview of Conservation Approaches and Technologies) investigates both unsustainable and SLM in Columbia, Indian Himalayas, Haiti and Iceland; identifying, assessing, and illustrating the onsite and offsite impacts of different SLM practices. Onsite investigations focus on the effects on land degradation, water availability and quality, resilience of land and people and biodiversity. Offsite impacts (often neglected and underestimated) focus on downstream water availability and quality (for domestic use, irrigation and hydropower), deposition of particles from windstorms, as well as disaster risk reduction related to floods, droughts and sand and dust storms.
Approaches and technologies giving both onsite and offsite benefits are emphasized in the findings and further documented in detail (WOCAT SLM database). The case studies prompt policy action and public support for investments that improve livelihoods, ecosystem services and natural resource management. Recommendations are focused on SLM-based approaches that enhance collaboration at the local, national and international level.
The project was implemented by WOCAT jointly with various partner organizations, and financially supported by the Swiss Agency for Development and Cooperation.
Key Terms
Onsite: locations where land management practices are applied – implementation site of SLM
Offsite: areas where land management practices (applied elsewhere) have an impact on the surrounding land and people, including areas downstream (related to water) or downwind (related to wind transport of sand, dust and moisture)
Benefits of action: economic well-being, climate resilience, environmental impacts (cleaner air and water, enhanced preservation of land and natural resources), community building, equity
Costs of inaction: yield losses, land and resource degradation, increased disaster risk and vulnerability to climate change, poverty
In this project, case studies to demonstrate the on- and offsite impacts were developed in four countries. The results and their implications for practice, policy and research are presented in Policy Briefs , videos and the documentation of several SLM Technologies and SLM Approaches. Furthermore, a Watershed Tool was developed and applied to assess on- and offsite impacts.
--> Only few cases are presented to raise awareness. If you are interested to share further cases, please contact us and we will send you further information and the instructions on how to develop, present and upload them on this website.
The following case studies have been selected to present a range of different on- and offsite impacts in different countries and contexts such as land management to reduce flood disaster risks (Haiti) to improve the recharge of springs (India and Haiti), to reduce damaging behaviour of rivers in a large watershed (Colombia) and to protect farmland and towns from devastating sand and dust storms (Iceland). The selection was strongly guided by the interest of WOCAT partner countries. Additional examples have been identified about phosphorous contamination and dying up of lakes in Switzerland and drinking water supplies for cities like Nairobi and hydropower generation in Kenya. Some results are presented will be presented to be further elaborated in follow-up projects.
