Realizing the full potential for cropland nutrient management would require the adoption of best practices and efficient nutrient management in agricultural systems across the globe. Most deforestation is driven by commercial agriculture; there are lots of opportunities to improve production on existing agricultural lands, so that we can avoid unsustainable forest conversion. Many interventions (such as establishing protected areas, improving land tenure and enforcing land-use laws) can be put into place immediately. Seagrass restoration is largely dependent on improving on-shore watershed and nutrient management practices. Improving timber harvesting practices in the south? Peatlands may be drained and converted to agricultural land or palm plantations. Halting all logging in forests would achieve maximum carbon sequestration, but an end to logging is neither realistic nor necessary. Worldwide, rice is grown on around 192 million hectares (an area nearly the size of Mexico) the vast majority of it in Asia. Extending harvest rotation cycles allows trees to absorb more carbon from the atmosphere, while increasing timber yields. In Southeast Asia, meanwhile, where mangrove forests are converted for aquaculture, palm oil production and rice farms, new regulations and viable economic alternatives will be necessary to curb wetland loss. Around the world, huge swaths of temperate and tropical forests have been cleared for human activity. In some areas, incentives such as subsidies might be necessary to improve rice production on a broader scale. There are many different agricultural practices that incorporate trees into existing cropping systems, and some form of these practices could be beneficial across a large share of cropland globally. One of the main challenges lies in communicating the benefits to farmers, and providing them with the technical support and services to encourage them to shift to a new (sometimes counterintuitive) method of farming. Given that climate change is driving an increase in the number and severity of storms, floods, and drought, even young children need to learn to be prepared. Changing grazing management practices is an intervention that could apply to 470 million hectares of rangeland worldwide â an area about half the size of Canada. Watch breaking news videos, viral videos and original video clips on CNN.com. In Brazilâs Pará region, small-scale farmers and ranchers have begun substituting their former crops and cattle ranching for cocoa agroforestry. Further, distributing new technology to remote villages can be difficult. The Pará region contains at least 1.26 million hectares of deforested areas that have naturally high-fertility soils and are suitable for cocoa production. Opportunities occur in most countries, including both large countries like Brazil, India, and the United States, and many smaller countries like Panama, Ecuador, and Benin. Maximizing Natureâs Role in Solving Climate Change, This Decadeâs Most Important Climate Solution, The Next Agriculture Revolution is Under Our Feet, Scientists hope wetland carbon storage experiment is everyoneâs cup of tea, Intact forest landscapes matter for climate change, Carbon farming is pathway to climate stabilization and resilient soils, Collaboration to  explore ways of working with natural systems to address climate change. There are 13.8 million hectares of mangroves, but there are still gaps in the data for mapping the extent of salt marshes and seagrasses: the estimated total cover of these three ecosystems is between 35 and 120 million hectares globally â less than 1% of the worldâs total land area. Due to the high demand for arable land, avoided grassland conversion is a relatively high-cost pathway. Peatlands are rare, covering only about 3% of the Earthâs surface. Cover crops arenât suitable everywhere: some areas in the tropics are already double-cropped, and other regions may not have the right conditions to support a second crop. Through the adoption of smart carbon farming practices, an acre of land could store anywhere from 10 to 100 tons or more of carbon, which can help both mitigate climate change and improve crop yields. Learn more about how our oceans and wetlands can help store carbon. That nitrogen is emitted into the air in the form of nitrous oxide, a greenhouse gas 300 times more potent than carbon. Despite some political and economic hurdles, we have the tools we need to stop deforestation now. That released from animal digestion (known as enteric methane) is a significant source of greenhouse gas emissions around the world. In such cases, policy changes will be necessary to reduce fertilizer use. The Code regulates land use on private property â and with 53% of Brazilâs native vegetation occurring on private properties, the law goes a long way toward protecting the nationâs native forests. What is required is a combination of avoiding further deforestation in critical locations, reforesting on degraded lands, and encouraging more sustainable production in timber plantations and logging concessions. However, the rate at which salt marshes and seagrass beds are being lost is uncertain. We need to support innovation in soil health to meet the growing demand for food while strengthening the health of our communities, land, water and climate. Many ranchers already over-seed their pastures with legumes to improve forage and productivity. Good animal management techniques include choosing improved livestock breeds, and promoting increased reproductive performance, lower mortality and increased weight gains. In addition, improved cook stoves would reduce smoke inhalation, providing significant health benefits, especially for women and young children. In some regions, improved rice cultivation will be expensive to implement. The Nature Conservancy and its partners are working to unleash the same zeal that promoted growth in the renewable energy sector to also stimulate a new wave of reforestation.Â. In other cases, reforestation can require active planting of trees and then long term care as they grow, and can be a relatively expensive form of land-based sequestration. This Philippines article wrote and helped my paper more than any other website and is the best for great information about Philippines and GO Filipino! This website, produced by The Nature Conservancy, is aimed at promoting the role of natural-based solutions in tackling climate change. Avoiding coastal wetland conversion is a low-cost climate mitigation pathway. Compared to other grazing practices, planting legumes in pastures has a more limited geographic potential, because it only applies to planted pastures that have a relatively low abundance of legumes to start with. However, simply creating more markets for wood and forest products is not the answer as this could create incentives for further deforestation. When forest loss is averted in one region, it is often âtransplantedâ to another part of the world. While the transition to low carbon energy will take decades, natural climate solutions could, and we argue should, provide a biological bridge to a low-carbon future in the near-term. Building companies working more with sustainable timber in construction. To avoid the conversion of grasslands, we must improve management of the worldâs existing croplands and continue efforts to intensify sustainable agriculture on those lands. Improvements in livestock feed could be applied to a significant number of the more than one billion head of cattle around the world. The UN Intergovernmental Panel for Climate Change reports that, by 2030, up to a third of its annual land-based emissions reductions targets could be achieved at a cost of $20 or less per carbon tonne. By planting cover crops on croplands that have an off-season fallow period, farmers can expand the length of time that photosynthesis occurs on cropland. World Resources Institute researchers share three reasons why protecting intact forest landscapes is crucial to the climate fight. National level maps do exist in a lot of places but there are gaps such as parts of Africa, Asia and South America. When rice is harvested, most of the remaining plant material is left in the ponds, where it sinks to the bottom and begins to decay. Peatlands also provide important habitat for many species. Stay informed about the latest in climate change science on Cool Green Science. Feeding animals energy-rich, easily digestible cereal grains can reduce the amount of methane thatâs released. Forest and savanna fires release large amounts of carbon into the atmosphere in a short amount of time. Farmer-managed natural regeneration (FMNR): managed recovery of native trees within dryland agriculture systems to protect and improve soils. Aside from the forestry sector, many other sectors can benefit from large-scale tree planting. Not All Forestry is Carbon Equal More efficient use of fertilizer can reduce a farmerâs costs without reducing productivity. Altering drainage patterns and local hydrogeography can be costly. Peatlands in Indonesia, for instance, provide prime habitat for orangutans. Seeing the Forest for the Trees Fast-growing starburst clerodendrum grows well in zones 9b to 11 and can be used as a shrub or tree. To prevent deforestation, we must take an integrated, global approach. Re-establishing coastal wetlands can be a relatively high-cost pathway although it varies according to ecosystem and geography.
