The study was conducted in Adami Tulu Jidokombolcha (ATJK), Bora, Dodola, Shala and Negele-Arsi districts with objective to assess main cattle feed resources, water sources and housing systems. A pre-tested, semi-structured questionnaire was used to conduct survey.  About 240 respondents were identified using random sampling techniques. Collected data was analyzed by SPSS statistical software (Ver. 24). Study result indicates that household in average had three hectares of land and allocated about two hectares of land for crop cultivation. Most respondents reported that cattle herding is not common during dry season while it is common during wet season.  Survey result indicate that natural pasture, weed and maize tiller and stored crop residues are main feed resources in wet  season while crop after math, crop residue and fodder trees are main resources during dry season. Brackish, local mineral and common salt are mineral sources for cattle in study areas. Lake, river and boreholes are important water sources in dry season where as ponds and rivers are main water sources during wet season for their cattle. The observed cattle watering frequency is mainly once a day. Housing system practiced in the study areas is mainly Kraal. The information generated from this study on land size per household, cattle herding system, feed resources, mineral sources, water sources, water utilization and housing type can be used as a baseline for any livestock development programs in those and similar areas.

In the tropics, there are too few studies on isolation ofBlastocystissp. subtypes from water sources; in addition, there is also an absence of reported studies on the occurrence ofBlastocystissp. subtypes in water during different seasons. Therefore, this study was aimed to determine the occurrence ofBlastocystissp. subtypes in river water and other water sources that drained aboriginal vicinity of highly endemic intestinal parasitic infections during wet and dry seasons. Water samples were collected from six sampling points of Sungai Krau (K1–K6) and a point at Sungai Lompat (K7) and other water sources around the aboriginal villages. The water samples were collected during both seasons, wet and dry seasons. Filtration of the water samples were carried out using a flatbed membrane filtration system. The extracted DNA from concentrated water sediment was subjected to single round polymerase chain reaction and positive PCR products were subjected to sequencing. All samples were also subjected to filtration and cultured on membrane lactose glucuronide agar for the detection of faecal coliforms. During wet season,Blastocystissp. ST1, ST2 and ST3 were detected in river water samples.Blastocystissp. ST3 occurrence was sustained in the river water samples during dry season. HoweverBlastocystissp. ST1 and ST2 were absent during dry season. Water samples collected from various water sources showed contaminations ofBlastocystissp. ST1, ST2, ST3 and ST4, during wet season andBlastocystissp. ST1, ST3, ST8 and ST10 during dry season. Water collected from all river sampling points during both seasons showed growth ofEscherichia coli and Enterobacter aerogenes, indicating faecal contamination. In this study,Blastocystissp. ST3 is suggested as the most robust and resistant subtype able to survive in any adverse environmental condition. Restriction and control of human and animal faecal contaminations to the river and other water sources shall prevent the transmission ofBlastocystissp. to humans and animals in this aboriginal community.

This research was done to identify livestock problems with the objective of assessing livestock production and associated constraints. The study was done using a formal survey, focus group discussions and field visit through open and closed ended questionnaires data collection. Purposive sampling was employed to select 90 households (HHs) having livestock and the data was analyzed by SPSS version 16. The average family size in the Abol (5.37) was significantly (P<0.05) lower than Lare (9.5) district. The levels of education in both districts were very low which nearly 57% of the households were without any kind of education. Trends in communal, arable and vegetation coverage were decreasing. Livestock rearing was them the means of livelihood of the population in Lare (78.7%) than Abol (21.7%) district. The average number of goats, sheep and chicken in Lare district were significantly (p<0.05) higher than Abol district. Natural pasture was the dominant feed resources in the area. The major livestock production constraints in the study area were ranked as health, feed, flood, drought, and theft and predators. From this study it was concluded that feed shortages occurs due to dry period and flood. Consecutively, poor conservation practices, storage of crop residues and improved forages which need effective training and demonstration to improve the productivity of livestock sector.

The first sustained effort to develop a ley farming system (a pasture legume rotated with a grain crop) for the Australian semi-arid tropics began in the late 1970s at Katherine, Northern Territory, where various strategies were identified and implemented. It was soon discovered that a main constraint to success was the invasion of the legume ley by grass weeds. This occurred despite the replacement of Townsville stylo (Stylosanthes humilis), which provided the base for the early work, with more competitive legumes such as Verano (Stylosanthes hamata) and Centurion centro (Centrosema pascuorum). Early weed control work focused on the use of chemicals, but later competition and population dynamics were studied in S. humilis pastures. The ley farming system comprised a number of essential elements, each of which offered opportunities for weed control First, a legume ley was rotated with grain crops. Past work concentrated on legume leys, but nitrogen (N)-fertilised grass leys may be successful if the N was economically supplied. Grasses can effectively suppress weeds. Rotation of herbicides is possible. Sicklepod (Senna obtusifolia) can be controlled with atrazine in the sorghum phase, and emergent Sida spp. can be controlled in the pasture phase using a herbicide roller. Second, cattle graze the legume ley and crop residues in the dry season. Cattle can be used to suppress grass weeds in the wet season. The major use of the legume ley, however, was to provide high quality food in the dry season when there was little other available food. Future research should investigate the economics of balancing the need for grass weed control with food provision in the dry season. Third, crops sown directly into a ley killed with a knockdown herbicide. Although the need for improved soil surface management was recognised early, development of reduced tillage was delayed until the availability of glyphosate. Initial work concentrated on improving plant establishment under mulch. Recent work has shown that mulches can effectively control weeds in crops without the use of herbicides; best weed control occurred when glyphosate was applied as a single application at sowing. Fourth, ley regenerated as an intercrop in the grain crop. There is no doubt that the presence of an intercrop reduces the yield of the grain crop. Future research should investigate the economics and risks associated with intercrop-induced changes in yield and herbicide use patterns. The extreme climate and sandy soils pose problems for herbicide use. There is marked seasonal variation in effectiveness of pre-emergence herbicides, ranging from zero to marked crop phytotoxicity. The effectiveness of knockdown herbicides is reduced by stressed target plants and rain soon after spraying. Mulch dynamics, grazing, competition and interference, and herbicide interactions with target plants and the environment, were identified as key features requiring attention in a ley farming system to achieve practical weed management.

The expected increase in livestock production to meet its increasing demand could lead to increased water depletion through feeds production. This study aimed at estimating the amount of water depletion through feeds and its corresponding productivity in livestock within the three dominant livestock management systems namely sedentary-intensive, sedentary-extensive, and transhumance in Yatenga and Seno provinces in the Sahelian zone of Burkina Faso. Using a participatory rapid appraisal and individual interview, beneficial animal products, and services were estimated, and consequently, livestock water productivity (LWP) as the ratio of livestock products and services to the amount of water depleted. Our results showed feed resources are mainly natural pasture and crop residues are common in all the management systems though the proportion of each feed type in the feed basket and seasonal preferences varied. Consequently, water depleted for feed production was similar across the systems in both provinces and ranged from 2,500 to 3,200 m−3 ha−1 yr−1. Values for milk (40 US$US$/household) and flock offtake (313 US$/household) derived from the transhumant system were higher (P &lt; 0.05) than those from other systems in the Seno province. With higher returns from the beneficial outputs, LWP was higher (0.11 US$ m−3) in the transhumant system than other systems in Yatenga, but similar with sedentary-intensive in Seno Province Multiple regression analysis results showed that LWP had a significant positive relationship with flock offtake in Yatenga but milk and flock offtake in Seno. The study concluded that sedentary-intensive and transhumant system with more market-oriented beneficial outputs and much dependence on less-water-depleted feed resources will improve livestock water productivity in dry areas. Besides, interventions to improve livestock water productivity through beneficial outputs must recognize the unique socio-cultural context of the livestock farmers.

Abstract. Lagoons are important ecosystems occupying large coastal areas worldwide. Lagoons contain various mixtures of marine and freshwater sources which are highly dynamic in time. However, it often remains a challenge to identify and quantify dynamic changes of water sources, particularly in heterogeneous lagoon systems like the Köycegiz-Dalyan Lagoon (KDL), which is located at the southwest of Turkey on the Mediterranean Sea coast. The objective of this study was to quantify different contributions of potential water sources i.e. surface water, groundwater and seawater in the lagoon and how these water sources changed over time and space. In the wet and dry season stable isotopes of water, chloride concentration (Cl-) and salinity were measured in two depths in the lagoon and surrounding water bodies (sea, lake, groundwater). Different components of water sources were quantified with a three component endmember mixing analysis. Differences in Cl- and stable isotopes over time indicated the dynamic behaviour of the system. Generally, none of the groundwater samples was impacted by water of the Mediterranean Sea. During the wet season, most of the lagoon water (>95%) was influenced by freshwater and vertically well mixed. During the dry season, high Cl- in the deeper sampling locations indicated a high contribution of marine water throughout the entire lagoon system due to salt water intrusion. However, a distinct layering in the lagoon was obvious from low Cl- and depleted isotope contents close to the surface supporting freshwater inflow into the system even during the dry season. Besides temporal dynamics also spatial heterogeneities were identified. Changes in water sources were most evident in the main lagoon channel compared to more isolate lagoon lakes, which were influenced by marine water even in the wet season, and compared to side branches indicating slower turnover times. We found that environmental tracers helped to quantify contributions of different water sources in the Köycegiz-Dalyan Lagoon which is a highly dynamic and heterogeneous groundwater dependent ecosystem.

However, it often remains a challenge to identify and quantify dynamic changes of water sources, particularly in heterogeneous lagoon systems like the Köycegiz–Dalyan lagoon (KDL), which is located at the south-west of Turkey on the Mediterranean Sea coast. The objective of this study was to quantify different contributions of potential water sources i.e. surface water, groundwater and seawater in the lagoon and how these water sources changed over time and space. In the wet- and dry-season stable isotopes of water, chloride concentration (Cl-) and salinity were measured in two depths in the lagoon and surrounding water bodies (sea, lake, groundwater). Different components of water sources were quantified with a three component endmember mixing analysis. Differences in Cl- and stable isotopes over time indicated the dynamic behaviour of the system.

Background: Accessibility to potable water is a fundamental right for dignity and well-being. Despite this observation, more than 1.1 billion people lack access to safe drinking water. This is particularly true in the Sub-Saharan Africa and South East Asia regions. Objective: The main aim of this study was to assess microbial quality of drinking water and prevalence of water-related diseases in Marigat town, Baringo County, Kenya. Methods: Samples of drinking water were collected from water sources (boreholes, rivers, and wells) and at the point of use (households) and analyzed for Escherichia coli and total coliform (TC) bacteria using the most probable number method. In situ measurements of pH and temperature were performed using a Wagtech International portable meter. Clinical health records from the local health centers were also reviewed to assess the prevalence rates of some of the water-related diseases. Results: There were significant differences among water sources during dry season for E coli (F2,21 = 3.629, P < .05) and TC (F2,21 = 4.041, P < .05). Similar observations were made during wet season for E coli (F2,21 = 4.090, P < .05) and TC (F2,21 = 1.893, P < .05). Furthermore, there were significant interactions between the water sources and season for E coli (F2,42 = 7.66, P < .01) and TC (F2,42 = 5.494, P < .05). Drinking water in large plastic storage containers (herein referred to as sky-plast) had the highest E coli and TC concentrations. Typhoid was the most prevalent water-related disease during the dry season (10%), whereas diarrhea (3%) was the most prevalent during the wet season. Conclusions and recommendations: All drinking water at abstraction and point of use for Marigat residents are microbiologically contaminated and therefore pose serious health risks to consumers of such water. Thus, there is need for public health awareness campaigns on household water management to curb incidences of water-related diseases. Public health practitioners at county and national levels need to ensure that households have adequate access to potable water and improved sanitation.
