农林系统具有多种效益,包括通过使用肥用树种来提高土壤质量,通过树冠改善小气候,以及生产薪柴和其他医药产品等森林产品以提高经济效益。农林复合经营有助于更好的土地管理、生计多样化和提高土地生产力。然而,政策制定者和其他利益相关方在农林业作为气候变化适应战略中作用的争辩却越来越多。本研究的目的是评估农林业作为气候变化适应战略的潜力。数据主要通过问卷调查从拉姆琼县Taksar的120名受访者中收集,采用卡方检验和二元logistic模型分析了影响气候变化适应策略的家庭选择因素。同样,通过访谈、讨论和观察以及后续的文件分析,对所获得的数据进行三角互证和验证。研究表明,农民采取了许多应对气候变化的策略,这些策略包括农牧多样化(71%)、使用改良作物品种、化肥和农药(73%)、农林复合经营(68%)、创收多样化(72%)、改变作物种植日期(57%)和复种措施(67%)等。从卡方检验和二元logistic模型中发现,“耕作经验”、“教育水平”、“农场规模”和“性别”对气候变化适应策略具有显著影响。农林复合经营具有不同的效益,如增加河流汇水(79.2%)、改善小气候(80.8%)、增加木材产品(71.7%)、提高粮食产量(83.3%)、改善牲畜健康和畜产品(77.5%)、提高土壤肥力(84.2%)和多样化生计选择(82.2%)。基于这些发现,该研究得出结论:农林复合经营是一种可以减少气候变化对当地环境影响的农业生产方法,推广和采用农林业可以帮助当地社区减少气候变化的影响。

Remote sensing and census based assessment and scope for improvement of rice and wheat water productivity in the Indo-Gangetic Basin

引用

Science China(Technological Sciences) 2009年第11期52卷 3300-3308页

作者： sharma bharat International Water Management Institute (IWMI) New Delhi Office NASC Complex CG Block Dev Prakash Shastri Marg Pusa New Delhi 110012 India

Understanding of crop water productivity (WP) over large scale, e.g., river basin, has significant impli-cations for sustainable basin development planning. This paper presents a simplified approach to combine remote sensing, census and weather data to analyze basin rice and wheat WP in Indo-Gangetic River Basin, South Asia. A crop dominance map is synthesized from ground truth data and three existing LULC maps. National statistics on crop area and production information are collected and the yield is interpolated to pixel level using moderate resolution imaging spectroradiometer (MODIS) normalized difference vegetation index (NDVI). Crop evapotranspiration is mapped using simplified surface energy balance (SSEB) model with MODIS land surface temperature products and meteorological data collected from 56 weather stations. The average ET by rice and wheat is 368 mm and 210 mm respectively, accounting for only 69% and 65% of potential ET, and 67% and 338% of rainfall of the crop growth period measured from Tropical Rainfall Measurement Mission (TRMM). Average WP for rice and wheat is 0.84 and 1.36 kg/m3 respectively. WP variability generally follows the same trend as shown by crop yield disregarding climate and topography changes. Sum of rice-wheat water productivity, however, exhibits different variability leading to better understanding of irrigation water management as wheat heavily relies on irrigation. Causes for variations and scope for improvement are also analyzed.

Tillage, crop residue, and nutrient management effects *** organic carbon in rice-based cropping systems： A review

引用

Journal of Integrative Agriculture 2017年第1期16卷 1-15页

Soil organic carbon （SOC） sequestration is one of the major agricultural strategies to mitigate greenhouse gas （GHG） emissions, enhance food security, and improve agricultural sustainability. This paper synthesizes the much-needed state- of-knowledge on the effects of tillage, crop residue, and nutrient management practices on SOC sequestration and identifies potential research gap, opportunities, and challenges in studying SOC dynamics in rice （Oryza sativa L.）-based cropping systems in South Asia, mainly in Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka. Improved management prac- tices such as reduced- and no-tillage management, nitrogen （N） fertilizer and farmyard manure （FYM） application, and crop residue addition can improve SOC accumulation. Positive effects of no-tillage, crop residue addition, N addition through manure or compost application, and integration of organic and chemical fertilizers on SOC accumulation in rice-based cropping systems have been documented from South Asia. However, limited data and enormous discrepancies in SOC measurements across the region exist as the greatest challenge in increasing SOC sequestration and improving agricultural sustainability. More research on SOC as influenced by alternative tillage, crop residue, and nutrient management systems, and development of SOC monitoring system for existing long-term experiments will advance our understanding of the SOC dynamics in rice-based cropping systems and improve agricultural system sustainability in South Asia.

Neurocysticercosis (NCC) vs Central Nervous System (CNS) Tuberculoma in Children—Dilemma over Clinico-Radiological Diagnosis?

引用

Open Journal of Pediatrics 2016年第3期6卷 245-251页

作者： bharat-Bhushan sharma Shashi sharma Department of Radio-Diagnosis SGT Medical College Gurgaon India Department of Pediatrics SGT Medical College Gurgaon India

Background: Neurocysticercosis (NCC) and central nervous system (CNS) tuberculomas often overlap in clinical presentation and imaging. Though the aetio-pathology entirely differs in both the scenarios but there is great confusion in their clinico-radiological evaluation as the findings and appearances are similar in many ways. The stress should be laid out over the salient features of each entity in the background of their presentation. The study was conducted to highlight the differentiation of the clinico-radiological findings in both the entities. Material and Methods: Ten patients between 5 - 15 years (mean age 10.4 years) with complaints of headache and with or without seizures had undergone MRI alone or with CT examinations. Basic sequences of T1W, T2W, T2W FLAIR and T1W contrast studies were carried out in all the cases. CT was carried out in only three cases and contrast was given in two cases. Results: Eight patients were having ring enhancing lesions in post contrast studies in MRI and two had only cystic lesions ranging from 1 - 3 cm in diameter. Conclusion: Seven cases having tuberculomas were confirmed by both the modalities with one case inconclusive. Two cases were diagnosed as neurocysticercosis as per the results. The reasonable achievable target was the goal to differentiate between NCC and tuberculomas in the brain and it was achieved. Contrast MRI and spectroscopy brought out many findings for the distinct features in many cases.
