Glyphosate, which is commercially available as Roundup®, was the widely used herbicide in Sri Lanka until 2015 and suspected to be one of causal factors for Chronic Kidney Disease unknown etiology (CKDu). This research, therefore, aims at studying presence glyphosate Aminomethylphosphonic acid (AMPA) different environmental matrices CKDu prevalent areas. Topsoil samples from agricultural fields, water nearby shallow wells lakes, sediment lakes were collected analyzed AMPA using LC/MS....
Summary 1. Water velocity plays an important role in shaping plant community structure flowing waters although few authors have yet attempted to explain the adaptation of plants flow. 2. We aimed test two hypotheses, that: (i) some emergent macrophytes reconfigure their shoot distribution fast currents and form clumps, (ii) shape morphology such clumps minimises drag caused by current. The study focuses on three that co‐occur along a gradient water velocity. 3. species showed clear zonation...
The 2004 tsunami is one of the most devastating natural disasters world has experienced in recent past, and it imperative that we learn from this experience about how to effectively implement post-disaster housing projects. Relatively little research been conducted study level satisfaction affected persons long term after receiving houses new settlements with ‘better’ socio-economic physical facilities. resettlement schemes established Sri Lanka provide an ideal setting factors affecting...
Background and Aims The latitudinal differences in the growth characteristics of Typha are largely unknown, although a number studies have pointed out effects climate on productivity Typha.Therefore, dynamic model was developed for to examine changes temperature radiation partitioning total biomass during growing season into rhizomes, roots, flowering vegetative shoots, inflorescences.Methods After validating with data from found past literature, it used investigate dynamics above-and...
A study of the effects Saguling Dam project has been conducted. This paper attempts to examine long-term dam construction on livelihoods displaced people, paying special attention any caused by inequality access resettlement schemes. The results indicate that majority resettlers perceived their as being better after resettlement. However, loss jobs or conversion less preferable beneficial occupations affected satisfaction level. In addition, options scheme differences in socio-economic...
Abstract Involuntary resettlement caused by dam construction, especially in developing countries, is being criticized as an additional cause of impoverishment the poor population resettled. Despite current improvements planning and implementation involuntary resettlement, there little experience or research on medium‐ to long‐term consequences those Within comprehensive water resource development programme Sri Lanka under Mahaweli Accelerated Development Programme, Kotmale Dam was...
Many of the negative consequences dam-related involuntary displacement affected communities can be overcome by careful planning and providing resettlers with adequate compensation. In this paper resettlement scheme Kotmale Dam in Sri Lanka is revisited, focusing on resettlers' positive perceptions. Displaced expressed satisfaction when income levels stability were higher addition to their having access land ownership titles, good irrigation infrastructure, water, more opportunities for...
Abstract We conducted a series of experiments in flume with cavity that provided refuge from the current to assess feeding behavior stone moroko Pseudorasbora parva . Feeding on commercial food pellets was quantified by assigning fish activity one components their predation cycle: pause, moving, pursuit (i.e., approach, chase, and attack), coasting, resting within cavity. Swimming speed highest during attack, followed coasting. As flow velocity increased, approach moving distances decreased...
