Farmers in China can manage their land for economic as well as environmental benefits, Stanford researchers find

Expanding monoculture threatens valuable services from land, such as flood control, water purification and climate stabilization. A new approach promises to protect these benefits, while improving biodiversity and human livelihoods in rural areas around the world.

The idea is that well-managed, diverse agricultural lands can provide flood control, water purification and climate stabilization, among other valuable services.

The group said the approach could help farmers worldwide protect both the environment and their livelihoods.

An island test case

Car Trailer Wiring Diagram Uk Working with government authorities, the researchers looked at how their proposed approach, called the “Ecological Development Strategy” could work in Hainan Island, a rural, tropical region where expanding rubber plantations have driven extensive loss of natural forest and its vital benefits, such as soil retention and flood mitigation. Although the economy grew due to the plantations, intensive monocropping practices increased sediment runoff and channeled agricultural chemicals into surface waters. Forest recreation and tourism disappeared. Flooding was exacerbated by the area’s loss of trees.

Pairing that information with survey data from households, the team used the Natural Capital Project’s Xplod Stereo Wiring Diagram to understand how changes in land use management could have garnered different results in natural forest or economic prosperity. Alongside the historical land data of almost two decades, the models helped researchers understand what could have happened if the land had never been developed for rubber plantations or if the plantations had been managed differently.

Federal Pacific Fuse Box Parts In particular, the researchers looked at one key land management change: a technique called intercropping that involves cultivating other valuable plants in the understory of a main crop. They found that rubber farmers who did this maintained the same production levels as monoculture plantations while significantly increasing soil retention, flood mitigation and nutrient retention. Perhaps most strikingly, farmers who took this approach doubled their incomes due to revenue from the additional crops. By diversifying their land, farmers also insured themselves against the risk of a single crop’s harvest failing or losing market value – key vulnerabilities of the monoculture system.

Broader applications

Pollak Trailer Plug Wiring Diagram 2001 Gmc Central to the Chinese Ecological Development Strategy is a focus on targeted investments in nature. Identifying places like Hainan where policy and management decisions can support both the economy and environment is crucial to achieve the widespread impacts that China is looking for. According to the researchers, this study illustrates how regions can leverage natural resources to support economic growth without sacrificing ecosystem health or human well-being.

Global climate insecurity, water contamination and species mass extinction are the result. The study’s authors emphasize that the science and practices exist to help drive a shift away from monoculture systems worldwide, and economic incentives await those who do.
