In search of a substitution model for coca in Colombia: Buffalo, cocoa, and coffee in Peasant Reserve Zones

open access: yesLatin American Policy, Volume 14, Issue 3, Page 388-407, September 2023., 2023
Abstract For years Colombia has been the world's largest coca producer. Its public management of crops for illicit use has swung between eradication, substitution, and, recently legalization. Forced eradication has been shown to be ineffective, and legalization is an incipient option, so the Peace Agreement puts forward substitution as the path to ...

Understanding Traditional Chinese Medicine to strengthen conservation outcomes

open access: yesPeople and Nature, Volume 3, Issue 1, Page 115-128, February 2021., 2021
Abstract Numerous treatments in Traditional Chinese Medicine (TCM) involve the use of wildlife products, including some that utilize ingredients derived from endangered flora and fauna. Demand for such endangered wildlife products in TCM can threaten the survival of species and pose serious challenges for conservation.

昭通烂泥箐滑坡源区原生状态根-土复合体抗剪特征

open access: yesShuitu Baochi Xuebao, 2022
以昭通烂泥箐滑坡源区优势物种鸢尾科鸢尾属鸢尾原生根系—土复合体作为研究对象,采用直剪试验对复合体抗剪特征进行深入研究,并与室内相同含水率重塑复合体试验结果对比分析。结果表明,整体上无根素土具有应变软化特征,而复合体具有应变硬化的特性,各复合体的抗剪强度均比素土的高,且抗剪强度随着含根量的增加而增加,根系加固效应明显,但复合体并没出现与重塑土类似的最优(最佳)含根量。原状复合体的c值随含根量的增加没有明显变化规律,而φ值则逐渐递增,其增长率也有相同的变化趋势。复合体破坏断面显示根系为主根系且垂直贯通剪切面,

苏北海堤林带树木根系固土功能研究

open access: yesShuitu Baochi Xuebao, 1994
该文通过对海堤林带树木根系及土壤抗冲,抗蚀和渗透性的测定分析,发现同一地段土壤的抗冲,抗蚀指数表土层大于底土层。树木根系,尤其是根径≤2mm的细根有较强的固特土壤功能,抗冲指数与根长,根量间有明显的相关性,单相关系数分别为0.9326和0.8256。吸机质含量高的土壤抗蚀性强,抗蚀指数大,与有机含量间的相关系为0.8931,与细根的根长和根量的相关性相对较低,单相关系数分别为0.8216和0 ...
