The document describes a study that used the SWAT (Soil and Water Assessment Tool) model to assess hydrologic processes in the middle Narmada River basin in India. Key inputs to the SWAT model included digital elevation data, land use/land cover maps, soil data, and weather data. The model was set up to simulate hydrologic response units based on land use, soil type, and slope. Model outputs included estimates of precipitation, temperature, evapotranspiration, and streamflow over the study period. Results indicated that about 46% of annual precipitation was lost to evapotranspiration in the basin. The study provides a hydrologic assessment of the basin using remote sensing and geospatial data within the SWAT

What is prioritization?
Prioritization is done to select the area of interest.
Prioritization is a process of identifying areas of main concern based on single or many parameters
Selection of one or few watersheds out of many watersheds by using predefined set of criteria.

CLIMATE change affects the components of water cycle such as evaporation, precipitation and evapotranspiration and thus results in large-scale alteration in water present in glaciers, rivers, lakes, oceans, etc. The effects of cli-mate change on subsurface water relates to the changes in its recharge and discharge rates plus changes in quantity and quality of water in aquifers. Climate change refers to the long-term changes in the components of climate such as temperature, precipitation, evapotranspiration, etc. The major cause of climate change is the rising level of greenhouse gases (GHGs) in the atmosphere such as CO2, CH4, N2O, water vapour, ozone and chlorofluorocarbon. These GHGs absorb 95% of the longwave back radiations emitted from the surface, thus making the Earth warmer. Except CO2, the effects of other GHGs are minor because of their low concentration and also because of low residence times (e.g. water vapour and methane). The rise in CO2 level causing global warming was first proposed by Svante Arrhenius, a Swedish scientist in 1896 and now it is a widely accepted fact that the concentration of CO2 is the primary regulator of temperature on the Earth and leads to global warming.

Modelling of runoff response in a semi-arid coastal watershed using SWATIJERA Editor
The GIS based hydrological model SWAT (Soil and Water Assessment Tool) is applied to a coastal watershed in the water scarce Saurashtra region of Gujarat, India, to understand the rainfall-runoff linkage. The study attempts to identify response of the coastal watershed for existing climatic conditions. The hydrological model is calibrated (2006-2009) and validated (2010-2012) at both daily and monthly scales. Performance of the model during calibration and validation period is evaluated through standard indices, NSE, R2 and PBIAS that indicate an acceptable response. At monthly scale, model performance is good for both low and above average rainfall years.

The primary source of water is rainfall for the generation of runoff over the land
surface. Runoff or overland flow is the flow of water that occurs when excess storm
water flows over the earth's surface. Satellite remote sensing and GIS techniques
coupled with conventional filed investigations were used for mapping of land use/land
cover (LU/LC) features of the Mini Watershed of Pedda Kedari reserve forest towards
estimating the runoff of the Mini watershed. The SCS-CN method (SCS, 1985) method
involves the use of a simple empirical formula and readily available tables and curves.
Determination of SCS curve number depends on the soil and land cover conditions,
which the model represents as hydrologic soil group, cover type, treatment and
hydrologic condition. Soils are classified into hydrologic soil groups (HSG) to indicate
the minimum rate of infiltration obtained for bare soil after prolonged wetting.
Runoff computed from a given rainfall event was integrated with the data of land
use treatment, curve numbers and hydrological soil groups by using SCS-CN method.
The estimated runoff contributes more than 37% of total rainfall received in the study
area. The suitable locations of rainwater harvesting and artificial recharge structures
are suggested to increase the groundwater levels for sustainable development of water
resources in the Mini watershed of Pedda Kedari Reserve Forest.
This study aims to analyze the hydrological characteristics as a result of changes
in land use with the help of the SWAT hydrological model and can provide
recommendations on the best land use in the Koto Panjang Electric Power catchment
area. Based on the results of the analysis using the SWAT hydrological model, it was
seen that there were effects of land use changes in 2011 and 2014 on hydrological
characteristics; yield of water (WATER YLD) of 2,413.38 mm, and 1.008, 65 mm,
runoff coefficient (C) of 0.19 and 0.063 respectively, and river regime coefficient
(KRS) of 11.449 and 12.212, respectively. The best land use to be developed in
agricultural cultivation areas as a recommendation to maintain water stability in the
Koto Panjang hydropower catchment area is a simple and complex agroforestry
pattern in scenario III, which is run together with hydrological characteristics in the
form; water yield (WATER YLD) of 1.038, 41, surface runoff coefficient (C) of 0.023,
and river regime coefficient (KRS) of 11.13. The hydrological characteristics in
scenario III are far better than 2014 land use characteristics (existing).

Extraction of Water-body Area from High-resolution Landsat Imagery IJECEIAES
Extraction of water bodies from satellite imagery has been broadly explored in the current decade. So many techniques were involved in detecting of the surface water bodies from satellite data. To detect and extracting of surface water body changes in Nagarjuna Sagar Reservoir, Andhra Pradesh from the period 1989 to 2017, were calculated using Landsat-5 TM, and Landsat-8 OLI data. Unsupervised classification and spectral water indexing methods, including the Normalized Difference Vegetation Index (NDVI), Normalized Difference Moisture Index (NDMI), Normalized Difference Water Index (NDWI), and Modified Normalized Difference Water Index (MNDWI), were used to detect and extraction of the surface water body from satellite data. Instead of all index methods, the MNDWI was performed better results. The Reservoir water area was extracted using spectral water indexing methods (NDVI, NDWI, MNDWI, and NDMI) in 1989, 1997, 2007, and 2017. The shoreline shrunk in the twenty-eight-year duration of images. The Reservoir Nagarjuna Sagar lost nearly around one-fourth of its surface water area compared to 1989. However, the Reservoir has a critical position in recent years due to changes in surface water and getting higher mud and sand. Maximum water surface area of the Reservoir will lose if such decreasing tendency follows continuously.
Rainfall runoff is one of the important hydrological variables in determining land
and water resources application. Curve Number method is widely used and efficient
method to estimate the infiltration characteristic of the watershed in accordance with
the land use/land cover property and soil property. In this study to estimate the
rainfall runoff modeling in this study area with an area of 152.81 sq km using Soil
Conservation Service Curve Number (SCS-CN) method and GIS. The estimated
amount average annual rainfall 1322.29mm from 1999 to 2013.The runoff varied
from 285 mm–4053mm, which is corresponds to 61.6% of annual average rainfall of
Thiruvalur district. These details are used for better watershed management and
conservation purpose.
To prevent losing water resources and wetlands, and conserve existing wetlands
ecosystem for ecosystem and biodiversity services, good, wetlands habitats forstart
any sustainable development programs, it is necessary to detect, monitor and
inventory water resources and their surround uplands. Recently, AL-Razaza Lake
suffer from a critical situation because of the decreasing in the water level and
increase a salinity. We have propose a method to monitor and model the spatial and
multi-temporal changes of AL-Razaza Lake in the period 1992–2018. This study
includes pre-processing, processing and post-processing stages. In Addition, a
supervised classification was used to classify the satellite images. Validation result
reveals that the overall accuracies and kappa coefficients of the supervised
classifications were 88, 90.79, 95.94 and 87.67 respectively, and 82%, 86%, 93% and
79% respectively. The results showed that the percentage change was significant
during this period, such that the decreased surface area was from 1313.87 km2 in
1992 to 224.85 km2 in 201.The noticeable results show the rapidly decreasing in the
Lake area by 82.8% with area about 1089.02 km2 over the last three decades. All the
dehydration extended area of the Lake was replaced by soil.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

INTRODUCTION
Water is one of the most important substances on earth.
All plants and animals must have water to survive. If
there was no water there would be no life on earth. Apart
from drinking it to survive, people have many other uses
of water for basic needs. India is the second most
populous country in the world. By the middle of this
century it needs to feed an extra population of 500
million. Second, India has had a huge economy and a
remarkable economic growth in the last decade. With the
booming economy, people’s expenditure patterns are
changing; rapid urbanization is also adding fuel to these
changes. The changing food consumption patterns are so
significant that they have a considerable impact on the
needs of future food and water demand. In India there
are significant spatial mismatches of the population and
water resources. Less water is available in places where
more people live and much of the food is grown. Some
river basins are already experiencing physical water
scarcities. A few others face problems of unsuitable
groundwater use. Thus, how India meets its increasing
food and water demand was the major focus of many
recent food and water demand projections at the global
scale (IWMI 2000) and the national scale.

ABSTRACT
Narmada, a river in central India flows in a rift valley through the state of Madhya Pradesh, Maharashtra and
Gujarat, plays an important role for water supply and ground water recharge. Therefore water resource
management and planning can be improved in a rift valley after accurate simulation of hydrological assessment. In
this study the Soil and Water Assessment Tool (SWAT) used on middle Narmada basin. The basic objective of the
present study is to derive parameters required for runoff modeling using the Remote Sensing and Geospatial
database and estimate surface runoff of middle Narmada basin. The main input data for simulation of SWAT
containing Digital Elevation Model (DEM), Land Use/Land Cover (LU/LC), Soil type, Soil properties and Hydro-
climatologically data, were appropriately collected. By providing all inputs for model set up, SWAT model was
simulated for the period of 12 years (1997-2008) and Validated with 2009 and 2010 year separately. The results
indicated that 46% of the annual precipitation is lost by evapotranspiration in the basin.
