Considering the time and funds available, stakeholders decided to restore the irrigation system of rice paddies in Antseva, Antsahavary and Antanambaonamboangisay villages. This will help the villagers grow rice and get water to the rice paddies even if the rains are late. Rice is a staple food in Madagascar and most rural families grow rice for their own consumption. Also, since water can become scarce, proper irrigation systems can improve water management in these villages. This reduces dependence on rainfalls and the risk of losing essential annual harvests.

您的社区在实施此解决方案时面临哪些挑战？
The main challenge was accessibility of the villages: villagers and workers had to walk for several hours to a whole day climbing and descending mountains to carry the building materials from the most accessible village to their villages. The solution to be implemented was identified in a participatory way with the villagers to make sure that it will match their needs and to get their support and ownership. They knew that the project?s role was to help but they will have tasks to undertake too. Though the irrigation system is simple and should be easy to maintain, there is always a risk of heavy rains causing land sliding and important damages. The water management committee?s financial and technical capacities to solve such problems are still low.
描述用于开发解决方案的基于社区的流程，包括使用的工具和流程
Prior to implementing adaptation measures, vulnerability assessments were undertaken in the target villages. The assessments looked into the natural system (humid forest and fauna) and into the human system (local communities). The vulnerability was a function of three parameters: exposition, sensitivity and adaptation capacity. The adaptation measures were defined based on the vulnerability assessments results and prioritized with different local stakeholders from the Upper Ramena area: local authorities (Commune and Fokontany), regional authorities, village elders, villagers representatives, governmental services (forest, water, agriculture), local NGOs etc. The adaptation activities were implemented by CRADES in collaboration with the local population during six months from September 2012 until February 2013. The funds were from the MacArthur Foundation to support WWF project on climate change adaptation in Diana Region (northern Madagascar). A community-based organization per village is insuring the irrigation system management: checking on repairs to be undertaken and mobilizing the beneficiaries.

您的解决方案如何减少暴露和缓冲/保护受影响的生态系统？
When the local people?s livelihoods are insured and they get enough food from their land, they will not clear up new forest areas. Indeed, forest soil is good and fertile but will turn sterile after 3 to 4 years. The irrigation systems reduce human pressure on the forests and enhance the forest ecosystem natural resilience to extreme climate events. A cleared forest is more exposed to droughts or erosion from heavy rains due to scarce vegetation cover.
How has your solution increased the capacity of the ecosystem to adapt to potential climate changes?
Farmers have been experiencing longer dry seasons during the last 10 years. Due to unreliable water supply to their fields, they cope by clearing up forest areas, grow rice for 3 ? 4 years then move to other areas. This practice is a big threat to the forests and reduces the natural capacity of the ecosystem to adapt to climate changes. Permanently providing water to rice paddies helps the farmers sustain their livelihoods and protect the forest from external threats.

N/A
您的解决方案如何降低受影响社区的敏感性？
Change of rainfall patterns and longer dry season affect the communities as their farming traditional techniques rely on the availability of water from rainfalls.
您的解决方案如何提高当地社区适应潜在气候变化的能力？
The solution which consists in restoring the farmers? irrigation systems allow the supplying of water to the rice paddies from permanent waterfalls. This increased the capacity of the communities to adapt to climate change impacts as they are less dependent to the rain and can grow rice all year long.
这个解决方案可以在其他地方复制吗？
Yes, it can be replicated to other villages within Upper Ramena area (7 other villages) and other villages in Madagascar facing similar problems. No, due to insufficient funding, this could not be replicated elsewhere yet. We plan to work in a fourth village this year.
