Long Term Changes

Bird Strikes (BS) are a significant threat to flight safety and a serious economic concern in the aviation industry. Variation of population and activity of different birds over an airfield leads to variation in their vulnerability for Bird Strike as well. In this study, an attempt was made to document the monthly variation of bird activity over three Indian airfields situated in different bio-geographical provinces in the year 2019-20. A significant activity of Black Kites (including the sub-species Black-eared Kite namely Milvus migrans govinda and Milvus migrans lineatus) and Lapwing (Vanellus indicus) were studied to understand their annual cycle as well as long term changes in their activity over airfields (over 30 years). Agra recorded an increase of 10.3 times in the activity of Black Kites in forty years. Black Kite data in correlation with the past information on Vultures indicate that the Black Kites are taking over the ecological niche of Vultures. Sirsa recorded an increase of 15 times in the activity of Red-wattled Lapwings in ten years and started dwindling again. The numbers of both species were stable over the Jodhpur airfield. The probable causes for long-term changes in Black Kite activity were identified as the type of waste management of the cities nearby, presence of other birds and migration. Similarly, changes in the activity of Red-wattled Lapwing could be partly attributed to the type of vegetation cover, long-term ecological changes, and intensive harassment of the bird. These findings will help airfield safety managers to initiate Solid Waste Management projects in the nearby city and monitor the bird population to control the major variations.

Breeding Migration

AbstractThe annual cycle of most animals is structured into discrete stages, such as breeding, migration and dispersal. While there is growing appreciation of the importance of different stages of an organism’s annual cycle for its fitness and population dynamics, almost nothing is known about if and how such seasonal effects can change through a species lifespan. Here, we take advantage of the opportunity offered by a long-term satellite/GPS-tracking study and a reliable method of remote death-detection to show that certain stages of both the annual and life cycle of a migratory long-lived raptor, the Black kite Milvus migrans, may represent sensitive bottlenecks for survival. In particular, migratory journeys caused bursts of concentrated-mortality throughout life, but the relative importance of stage-specific survival changed with age. On the other hand, the balance between short-stages of high mortality and long-stages of low mortality made population-growth similarly dependent on all portions of the annual cycle. Our results illustrate how the population dynamics of migratory organisms can be inextricably linked to ecological pressures balanced over multiple stages of the annual cycle and thus multiple areas of the globe, suggesting the frequent need for challenging conservation strategies targeting all portions of a species year-round range.

This paper reviews the current practice and challenges of community participation on waste segregation program in Jasin Malacca since 2015-2017. The Solid Waste Management and Public Cleansing (Act 672) which came into force on 1st September 2011, is Governments’ effort to provide a systematic, coordinated, effective and efficient solid waste management system in Malaysia including Malacca.. Since then, there has been significance increase on the amount recycle waste collected. However, the community participation on solid waste segregation and recycling program still at low level due to lack of awareness, attitude and exposure on the advantages of recycling in the long term. Thirty preliminary questionnaires were distributed randomly at resident’s housing area in Jasin and analysed through Average Index (AI) method. The result obtained shows the current challenges of the community in performing the waste segregation at source. From the result, further study will be conducted to discover new approach on promoting waste segregation which could provide the basis for success of 3R program in Malacca.

Long Term Impact

The increasing quantity of solid waste is one of the serious environmental problems in Sagarmatha National Park trekking route. Tourists, trekkers and mountaineers litter the route with plastics, cans, bottles, papers etc. on trails. The lodges, hotels and restaurants also do not have better solutions. The trekking routes from Lukla to Everest Base Camp are littered by more than 30,000 visitors coming to the region within a year. The main reason is due to the concentration of the studies of solid waste mainly in urban areas, lack of environmental awareness and public as well as local participation, lack of understanding of the complex mountain ecosystem and negligence of long term impact to tourism industry.´There have been various initiatives and researches carried out by Sagarmatha National Park (SNP), Sagarmatha Pollution Control Committee (SPCC), Nepal Mountaineering Association (NMA), Ev-K2-CNR and various other agencies including NGOs despite which the situation still remains to be resolved and demand further improvement. This paper describes the observations study on SWM carried out during the trekking by Nepalese and Swedish researchers in April 2010 and recommendations drawn out from the study. The issues raised and the problems identified during the study would need to be properly addressed, which would be instrumental in finding way forward and augment the planning of the daunting tasks of Solid Waste Management in the region.
