In order to obtain adequate water resources, the decision to build water reservoirs is unavoidable. However, the large amount of sand and rocks washed out from upstream shortens the lifespan of the water reservoirs. Therefore, the sediment needs to be cleared away to prolong the lifespan of the reservoirs, secure the water storage in the water reservoirs and improve their efficiency to achieve the best economic benefits. This research aimed to discuss the reasons for geographical and environmental change, as well as natural ecological destruction due to construction of water reservoirs. The findings could serve as a reference to further ecological engineering projects to restore ecological and geographical conditions, and to improve the land degradation situation caused by the construction of water reservoirs.

Mosquitoes have a very important meaning in the health sector because of their role as vectors of various diseases. Diseases transmitted by mosquitoes include dengue fever, malaria and filariasis. These three diseases are transmitted from one person to another through vector intermediaries. Vector is a creature that acts as an intermediary for transmitting   diseases. Tebing Tinggi Village is a densely populated area. The density of the population as well as the constraints of clean water make a lot of water reservoirs to store daily water needs. This can potentially be a breeding ground for mosquito larvae. This study was conducted to determine the density of mosquito larvae, to find out the percentage of house index and container index. This study used a visual method, with a cross sectional approach. Based on the results of research from 18 houses (19.78%) that were larvae positive from 91 houses examined and found 22 containers (5.78%) positive larvae from 380 containers examined. 331 containers of larvae were found in the reservoir of deep water as much as 18 containers (5.43%) and as many as 49 containers of  larvae were found in the external water reservoir (12.24%). The density of mosquito larvae in Tebing Tinggi area is categorized as being with density figures 3 and 4. The amount on the surface of the presence of mosquito larvae in water reservoirs in the house should  the community pay more attention to the cleanliness of water reservoirs and to close water storage so that they are not breeding grounds.

Pekanbaru is one of the cities in Riau Province which is an endemic area for Dengue Hemorrhagic Fever (DHF) with the Incidence Rate exceeding the endemic limit of 148,80 per 100.000 population. The purpose of this research was to determine the influence of the distance between houses, water storage condition, the existence of garbage, the existence of larvae around the houses. To determine attitude, knowledge, eradication of mosquito nests, the morning and or afternoon sleep habits, the habit of hanging clothes, and the existence of ornamental plants on Dengue Hemorrhagic Fever (DHF) cases.  The type of research was observational quantitative analytic with a Case-Control design. The sampling technique used was Non-Probability Sampling and multivariate analysis used is multiple logistic regression. The sample was 138 respondents and Primary data collection using questionnaires and observation sheets. Six variables affecting the DHF cases were the existence of larvae (OR=8.103), eradication of mosquito nests (OR=6.230), water storage conditions (OR=2.136), the sleep habits in the morning and or afternoon (OR=2.058), the existence of garbage (OR=0.233) dan knowledge (OR=0.165). This suggests that the community can do eradicate mosquito nets. . Eradicating mosquito nests can be carried out through 3M Plus activities, including regularly draining the bathtub at least once a week, changing the water in flower vases, bird drinking places, or other water reservoirs regularly every less than one week. Closing water reservoirs tightly. Utilizing / recycling used cans, plastics, used tires, and other items that can hold rainwater so that they do not become mosquito breeding grounds. Six variables that influence the DHF cases, were: the existence of larvae, the action of 3M Plus, the condition of the water reservoir, the habit of sleeping in the morning and afternoon, the existence of garbage, and knowledge. Four variables did not affect the DHF cases, they were: attitude, the distance among houses, the habit of hanging clothes, and the existence of yard/ornamental plants. The community is expected to be able to recycle waste (garbage that has the potential to hold water).

Abstract. Conflicts between pastoralists and farmers in the Sahel arise from competition over land and water resources or because of livestock damages to crops. Rather than being linked to larger environmental change processes such as climate change, they are often causes by inappropriate zoning of land, governance and unequal power relations between stakeholders in the conflicts. In this paper, we explore whether improved weather and resource information and improvement in its communication could prevent conflicts or reduce their severity. Based on a survey of key stakeholders and studies on pastoral access to and use of information, we conclude that improved information may both reduce and increase the level of conflict, depending on the context. Communication of improved information will need to go beyond just the weather and resource information and also include the multiple options for herd movements as well as providing information on herd crowding and potential conflict areas.

Resources Development

It is said tluit civilization began and prospered when humans could control water; and that same civilization declined and vanished when that control is lost. Dams and other river flow barriers were built to harness and control water in the early days of civilisation in order to secure the benefits for human basic needs and comfort. Centuries later, more dams were built to cater for increasing population, especially in arid and semi-arid areas. But it is really in the past two centuries that many large-sized dams have been built to satisfy a wider range of development demands — hydropower, treated water supply, irrigation, flood control and environmental needs.Towards the second half of the last century, society came to realise that dams can cause significant negative social and environmental impacts that could outweigh the original economic benefits. Opponents of dams protest vehemently world-wide against the development of more dams whilst proponents are convinced tluit the y are a necessary feature to support growth and prosperity. It is these contradicting beliefs in mind tluit the public must be engaged to facilitate a better understanding of the views of both the proponents and the opponents of dam development before deciding on a long-term strateg y. In the meantime, more effort may have to be made for water and energ y conservation strategies and to realize the potential applications of low impact and non-structural solutions that complement existing dams and defer new dam development to as far into the future as possible.This paper aims to provoke a critical debate amongst engineers and the public to look at the longer term future ofdams in water resources development that could possibl y reduce the fundamental demand for services that dam provides. In other words, to try and answer the question “Why should a country rich in water, as Malaysia is, need to construct dams and even plan for more?”

Mixing Problem

Pollution of sub-surface water reservoirs mainly rivers and streams through contaminated water point sources (CWPS) was studied. The objective was to formulate a discrete time delay mathematical model which describes the dynamics of reservoir pollution using mixing-problem processes that involve single species contaminants such as nitrates, phosphorous and detergents. The concentration  of pollutants was expressed as a function of the inflow and outflow rates using the principle for the conservation of mass. Systems of ODEs generated from principles of mixing problems were refined into a system of DDEs so that the concentration of pollutant leaving the reservoir at time would be determined at some earlier instant, for the delay. The formulated model is a mathematical discrete time delay model which would be used to describe the dynamics of sub-surface water reservoir pollution. The results from the validation of the model were analyzed   to determine how time delays in the mixing processes affect the rate of particle movement in water reservoirs.

The research samples were all mosquito larvae andcontainers found. The research respondents were all cleaning services. Data werecollected by interviewing and filling in questionnaires, observing water reservoirsand identifying the types of mosquito larvae in microscope. Results A total of 40containers were found in Punti Kayu Nature Park. There were 8 containers that wereindoors (20%) and 32 containers were outdoors (80%) with 17 containers containedlarvae. Of all the containers that were positive for larvae, 6 were filled with clearwater and 11 were filled with turbid water. The number of larvae found were 358larvae outdoors and 82 larvae indoor with a total of 440 mosquito larvae with thegenus Culex spp. and Aedes albopictus species. The index of mosquito larvae wereobtained FLI (Free Larva index)=66,67%, HI (House Index)=33,33%, CI (ContainerIndex)=16,67%, BI (Breteau Index)=33.33% from the 3 buildings examined. Fromthese results, it was obtained DF (density figure) or density level of 5. There were 40containers that could be habitats for Culex spp. and Aedes albopictus. ConclusionThe knowledge, attitude and behavior of the cleaning services were good. Thenumber of mosquito larvae could be influenced by the frequency of cleaning and thelack of knowledge of the cleaning services.

Runoff signatures (RS), a special set of runoff indexes reflecting the hydrological process, have an important influence on many fields of both human and natural systems by flooding, drought, and available water resources. However, the global RS changes and their causes remain largely unknown. Here, we make a comprehensive investigation of RS changes and their response to total water storage anomalies (TWSA) from GRACE satellites, atmospheric circulation, and reservoir construction by using daily runoff data from 21,955 hydrological stations during 1975–2017. The global assessment shows that (1) in recent years, the global extreme flow signatures tend to decrease, while the low and average flow signatures are likely to increase in more regions; (2) the spatial patterns of trends are similar for different RS, suggesting that the runoff distribution tends to entirely upward in some regions, while downward in other regions; (3) the trends in RS are largely consistent with that in TWSA over most regions in North America and eastern South America during 1979–2017, indicating that the GRACE-based TWSA have great potential in hydrological monitoring and attribution; (4) atmospheric circulation change could partly explain the global spatiotemporal variation patterns of RS; (5) dams have important influences on reducing the high flow signature in the catchments including dams built during 1975–2017. This study provides a full picture of RS changes and their possible causes, which has important implications for water resources management and flood and drought disaster assessment.
