减少拉丁美洲的碳足迹意味着恢复生命以退化土地
关于气候变化行动的大多数讨论都集中在能源和行业上,因为这些部必威官网是真的吗门驱动了发达国家的温室气体排放。但是在拉丁美洲,气候变化在很大程度上是土地利必威官网是真的吗用问题。
Nearlyhalfof all greenhouse gas emissions in Latin America and the Caribbean (LAC) are the result of land-use change, forestry, or agriculture. Between 2001 and 2012, the region损失了3600万公顷of forest and grassland to agricultural expansion. Latin America now holds at least2亿公顷退化的土地,主要是由于不可持续的农业实践。
因此,有一个明确的解决方案来遏制LAC地区的气候变化 -必威官网是真的吗恢复生活to its degraded landscapes.
那就是那里倡议20x20comes in, a new partnership between governments in Latin America, WRI, theInternational Center for Tropical Agriculture (CIAT), theTropical Agricultural Research and Higher Education Center(catie),International Union for the Conservation of Nature(IUCN)和私营部门投资者。该倡议旨在改变该地区土地修复的动态,并最初着重于将2000万公顷的退化土地带入2020年。“mosaic”of trees, crops, and livestock. So far, seven countries—Chile, Mexico, Guatemala, Costa Rica, Colombia, Ecuador, and Peru— and two regional programs, Bosques Modelo and Conservacion Patagonica, have already committed to restore just over 20 million hectares of degraded land, with private sector investors earmarking US$365 million to finance their efforts.
经过restoring degraded land to natural forests or mixed agricultural systems and by directing agricultural expansion to already degraded lands, Latin America and the Caribbean can significantly reduce its land use-related emissions, making it feasible to contribute to global climate stabilization goals. Planting new trees and allowing trees to regrow naturally can sequester carbon dioxide, while more effectively using already degraded landscapes for agriculture can avoid further deforestation. Plus, restoration can产生其他重大好处,例如提高水和土壤质量,提高粮食安全,改善农村生计以及保护或恢复生物多样性。
案例研究:厄瓜多尔
Ecuador is one of the first countries to join Initiative 20x20, where the Ministry of Environment created a new program to restore half a million hectares of degraded land to forests. The program, called Socio Bosque, works by providing monetary incentives to farmers to restore and protect forests on their property. The process, which will occur over many years, will sequester carbon, increase water quality, preserve biodiversity, and provide a new source of income for the landholders from the government. Although a small country, Ecuador has more than 7 million hectares of land with restoration potential, and the country could increase its domestic target following a successful Socio Bosque program.
案例研究:墨西哥
主动性的3个活动20x20:
- Inspire national commitments to restoration by engaging in a robust dialogue with Ministers of Agriculture and Environment in the region;
- 通过评估恢复和避免森林砍伐的社会福利来提出经济案例;和
- Establish a financial mechanism that allows private sector impact investors to fund restoration projects
扩展修复
Twenty million hectares is just the beginning for restoration in Latin America and the Caribbean. This initial goal helps to establish the importance of addressing the dynamics of land degradation in the region, and hopefully, will lead to larger, more ambitious targets in coming years.
