Geospatial data and web based tools for managing irrigation infrastructure expansion projects
World Water Policy, Volume 9, Issue 3, Page 388-403, August 2023., 2023 Abstract Improving irrigation infrastructure is important for sustaining food security in developing countries like India. The irrigation potential of a system is estimated at the planning phase using conventional approaches. A mismatch in the irrigation potential planned to be created and the land suitable for cultivation can lead to a gap in the ...

Challenges of and opportunities for protecting European soil biodiversity
Conservation Biology, Volume 36, Issue 5, October 2022., 2022 Abstract Soil biodiversity and related ecosystem functions are neglected in most biodiversity assessments and nature conservation actions. We examined how society, and particularly policy makers, have addressed these factors worldwide with a focus on Europe and explored the role of soils in nature conservation in Germany as an example. We reviewed past

Rewilding in the face of climate change
Conservation Biology, Volume 35, Issue 1, Page 155-167, February 2021., 2021 Abstract Expansion of the global protected‐area network has been proposed as a strategy to address threats from accelerating climate change and species extinction. A key step in increasing the effectiveness of such expansion is understanding how novel threats to biodiversity from climate change alter concepts such as rewilding, which have underpinned ...

Shuitu Baochi Xuebao, 2005 对辽宁省主要设施栽培地区土壤盐分累积变化规律的凋查研究结果表明：（1）设施栽培土壤盐分含量和电导率较露地土壤有明显增加，且变化幅度较大，是露地的2.0～6.0倍。沈阳、北宁两地设施土壤的盐分含量分别为1347.48mg／kg（CV=59.3％），1274.25mg／kg（CV＝40.5％）。（2）设施土壤连续种植到4年左右为盐分累积的高峰期，此时土壤的平均含盐量为1861.28mg／kg，EC值为0.53mS／cm，已超过所种作物的生育障碍临界点（EC〉0.5mS／cm）。此后 ...

Shuitu Baochi Xuebao, 2006 采用定点取样的方法，研究了不同种植年限设施土壤微生物主要类群、生物量碳和5种酶活性的变化特点，结果表明：（1）不同种植年限设施土壤微生物主要类群随季节变化不一致，细菌数量先升后降，高峰出现在6月，10月最低；真菌和放线菌数量均在3月最多，而后逐渐减少。随设施种植年限的延长，微生物总数逐渐增加，但真菌和放线菌占微生物总数的比例却呈下降趋势。与露地相比，设施栽培中真菌增加快于细菌。（2）不同种植年限设施土壤微生物生物量碳在3月和6月含量最高，随设施种植年限的延长，微生物生物量碳含量也增加。（3 ...

生物基磺酸盐改良剂对盐碱土的改良效果及油葵生长的影响 [PDF]
, 2018 为研发生态导向型盐碱地治理修复技术解决黄河河套宁夏平原土壤盐碱化,设计不同水平生物基磺酸盐改良剂用量(0、750、1 500、2 250、3 000kg·hm-2)进行盆栽试验。结果表明,生物基磺酸盐改良剂可有效降低盐碱土pH和全盐质量分数,促进油葵生长发育,但施用量过高会起到相反作用。当生物基磺酸盐改良剂施用量为2 250kg·hm-2时改良效果最佳:油葵蕾期土壤pH、全盐质量分数最低达到9.63和0.77g·kg-1,较对照（CK）分别下降6.14%和62.07%;油葵叶片抗氧化保护酶过氧化氢酶 ...

Review of Policy Research, Volume 42, Issue 6, Page 1428-1449, November 2025.ABSTRACT In Colorado, cattle farming—the state's leading agricultural sector—is a significant source of methane emissions. In response, both the government and producers have initiated efforts to mitigate the effects of climate change and enhance sustainability.
