Geospatial data and web based tools for managing irrigation infrastructure expansion projects
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
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
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 ...

Desertification is increasing in the Brazilian Semiarid, leading to loss of species and ecosystem services, while precise data on biodiversity distribution and trends are lacking. Public engagement in scientific projects can improve ecosystem protection.

Indian Pangolin in Lamjung Requires Urgent Attention 尼泊尔拉姆琼县地区的印度穿山甲急需关注
This study documented the first evidence of the Indian pangolin in Lamjung district, Nepal, finding three burrows and rescue evidence in Simalchaur Naringhat Community Forest. The burrows identified at an elevation of 530 m and characterized by moderate crown and ground cover (26%–50%), a 25° slope, and predominantly red soil, are indicative of a ...

Abstract Sustaining agricultural production in arid and semi‐arid regions is of paramount importance to food security, geo‐political independence, and social stability. In this context, it is vital to understand the effectiveness of policies. In this article, we aim to answer the question of what role the state and its policies play for soil protection

通过探究不同灌溉水平下施用生物有机肥对红枣田土壤水分、盐分及土壤养分属性的影响,为红枣种植提供适宜的水肥方案。设置2个灌溉水平(W1:6 000 m3/hm2,W2:6 600 m3/hm2),3个基施水平(S1:1 200 kg/hm2,S2:1 650 kg/hm2,S3:2 100 kg/hm2),以不施加生物有机肥作为对照(W1CK,W2CK),共8个处理,开展田间试验。施加生物有机肥可以提高土壤含水率、土壤有机质和总碳含量,且同一灌溉水平下,随施肥量的增加均表现为S3>S2>S1>CK ...

土壤中稳定的团聚体为碳的固定提供良好的物理保护,同时土壤中的碳又会促进团粒结构的形成,二者相辅相成,但在长期稻草和生石灰添加介导的设施内土壤中二者如何变化,却少见报导。以长期施肥定位试验为依托,采用湿筛法研究了施用鸡粪(M)的基础上,配施稻草(R)和生石灰(Ca)对设施土壤团聚体组成、稳定性及碳分布的影响,以不施肥(CK)为对照。结果表明:(1)在鸡粪基础上加入稻草(MR)或生石灰(MCa),与单施鸡粪(M)相比,>0.25 mm团聚体含量分别增加了123%和37%;稻草和生石灰同时添加可显著增加5~2

为探明3种灌溉方式设施土壤N2O排放特征及相关因素的影响,通过田间试验与室内分析相结合的方法,采用静态箱—气相色谱法与实时荧光定量PCR(Real-time PCR)技术分析不同灌溉方式(滴灌(D30)、渗灌(S30)、沟灌(G30))土壤N2O排放特征的差异以及土壤温度、湿度、无机氮、反硝化细菌对土壤N2O排放的影响。研究结果表明,灌溉后1~8 d设施土壤会出现明显的N2O排放高峰;整个番茄生长季沟灌处理土壤N2O平均排放通量最大,分别较滴灌和渗灌处理高出52.74%和50.82%;与沟灌处理相比 ...
