Abstract

Cattle are reared for milk and dry periods are considered loss to the exchequer of livestock farmers. To avoid it, farmers mostly abandon the cattle to become stray animals. Latest research supports that cow dung and urine are endowed with versatile medicinal, biofertilizer and bio-pesticide properties of socioeconomic importance. This has given the concept of dry cattle farming where focus is utilities of cow dung and urine and their value added products. Cow urine is useful for numerous human ailments like, cancer, osteoarthritis, allergies, kidney failures, skin diseases, healing of wounds etc. Cow dung is main source for vermicompost, FYM and biogas. Many products containing cow dung and urine i.e. soap (23% cow dung content and 7% urine), toothpaste (10% cow dung content and 10% urine, 2% Ghee), floor cleaners (Gaunyle: 11% cow urine), hair oil, incense shaving cream, face wash, talcum powders and dark circle removers are available in the market. The term cowpathy has been coined for diverse uses of cow dung and urine and is now focal area of research and innovative products development. Further, the dry cattle farming offers solution to problems of stray animals and helps in empowering the women farming community to exploit dry farming for more profit, product development and economic strengthening.

Abstract

Women play a critical and potentially transformative role in agricultural growth in developing countries but they face persistent obstacles and economic constraints limiting their potential inclusion in agriculture. The feminization of agriculture is determined by two major factors, first compared to men, women have much poorer access to and control over productive resources and they have inadequate access to public services, such as training, extension and credit. Women farmers often lack the know-how and the confidence to use the improved technology and most of the new technologies. The reason being most of these advancements are aimed at male specific end users. Giving support to rural women is a way of breaking the vicious cycle that leads to rural poverty so there is need to cut the drudgery of women farmers and make their efforts worthwhile and economical. Development strategies should consider rural women as the epicenter, paying special attention to their social skills both within and without agriculture sector. In terms of equity, women overall have lower awareness of AAS than men do, indicating the importance of targeting women in communications efforts. More trainings are required to generate interest and motivate farm women to learn about the AAS and use it. Closing the gender productivity gap could increase agricultural output in by a significant amount. Increased production would also imply increased food availability and reductions in undernourishment. Integrating Gender and Agriculture within Agricultural Extension System empowers families, helps women to contribute to household incomes, increases productivity & reduces gender gaps in agriculture.

Abstract

84 per cent of the Indian rural women livelihood depends on agriculture. It is estimated that 52-75 per cent of the Indian women engaged in agriculture are illiterate. Prevalence of anaemia among pregnant women ranges between 50%-90%. From these facts it infers that ghost of food and nutritional security haunts the rural women health and prosperity. Female participation in the economic activities also determines the sex ratio because the work determines the worth in the society. It has been observed that in those families where women participate in economic activities, this problem is not severe as compared to those families which do not participate in economic activities. Diverse areas of entrepreneurship exists in rural India for women empowerment. This potential can be realized through policy and infrastructure support from the government and by strengthening proactive synergies among various farm and non-farm sectors activities. Although we are proud of the Indian women in the global arena yet we have peer into the atrocities against them in the name of female foeticide, gender inequality, sexual harassment, dowry system and many more evils with promotion of involvement in socio-economic enterprises, if rural transformation is to be achieved.

Abstract

Women work two-third of the world’s working hours, produce half of the world’s food yet 60% of the world’s hungry are women. They earn only 10% of the world’s income and own less than one per cent of the world’s property. It reveals deep-rooted gender disparity in human society. But I perceive the secondary agriculture an emerging area with vast opportunities for socio-economic transformation and women empowerment across the globe in a way that conventional agriculture doesn’t have. Secondary agriculture is less affected by climatic factors, relatively stable and more amenable to feminization because of off-field nature. If properly supported it could be an effective tool to promote women empowerment and narrow down gender disparity in rural areas. Secondary Agriculture is not a Secondary Sector economic activity and it broadly embraces to product development through agro-processing (food and nonfood), within the all enterprise classes of small or medium or large scale industry. Being entrepreneurial in nature it assures better remuneration and socio-economic security than primary agriculture. An orientation from production agriculture to product development is an essential pathway to sustainable women empowerment as it will lead to shift from subsistence farming to business farming. Later has the potential to contribute to a range of social and economic developments such as employment generation, income generation, poverty reduction and improvements in family nutrition, health and overall food security to the persons engaged in agri-business farming.

Abstract

Women entrepreneurship means the process in which women initiate a business, gather all resources, undertake risks, face challenges, provides employment to others and manage the business independently. Where women population hovers around 50% of the total human population in the world so entrepreneurship by them plays a key role in the development of economy of both developed and developing nations. The problems faced by women entrepreneurs are heavy work load, irregular payment, lack of work guarantee and no maternity benefits, health problems, marketing, financial liberty and being away from home. A different culture is required to promote, motivate and develop sustainable infrastructure for fostering women entrepreneurship. Often, an entrepreneur has to go through a complex set of procedures and formalities to start a business, which not only create irritations and delays but frustrate her efforts until she is exhausted. An urgent need, therefore, is to simplify procedures and formalities. Part of the problem is one of attitudes, which are built on regulatory roles rather than developmental roles. All training and financial agencies need to be gender sensitive. The time has come for an effort to inculcate a spirit of enterprise, self-dependence, creativity, and high goals among women in developing nations. Hence, entrepreneurship must be made part and parcel of the education curriculum.

Abstract

India is one among the major fruit producing countries of the world and offers opportunities of women empowerment through quality fruit production, planting material generation and production of value added products. There is a great opportunity to increase and improve the production of tropical, subtropical, and temperate fruits. Underutilized fruits also have a huge potential waiting to be exploited. This will only be possible with a concerted effort by researchers and growers, especially women to improve quality and increase production based on consumer demand and export potential. Women play significant role in fruit production activities. Unfortunately their access to knowledge, technology, finance, information, and training is minimal which hampers productivity of fruit crops. The mode of female participation in agricultural production varies with the land owning status of farm households. Their roles range from managers to landless labourers. In all farm production, women’s average contribution is estimated at 55 percent to 66 percent of the total labour with percentages much higher in certain regions. About 48 percent of India’s self-employed farmers are women. Thus, rural India is witnessing a process of transition which could be described as feminization of agriculture particularly fruit crop cultivation and their post harvest management. Women play an active role in various production and postproduction activities of horticultural crops. The number of women engaged in horticulture has increased continuously in the past two-three decades due to various factors such as migration of men to urban areas in search of non-farm income, increase in the demand of labour force in construction and other sectors. The data on the women involved in horticulture sector are scanty however the involvement of women in various operations of cultivation and post harvest handling and storage is very high because of entrepreneurial nature of horticulture. There is need to adopt collective and SHG approach to take women contributions to socio-economic significance. Thus horticulture, especially the pre-harvest and post harvest management of fruit crops have considerable employment avenues for women and make horticulture an effective subject of women empowerment.

Abstract

Gender equity is more pronounced in livestock sector where more than 70% participation is from women side as compared to 33% in agricultural farming. About 75 million women are engaged in livestock sector. In India, livestock production is largely in the hands of women. In fact animal husbandry is becoming feminized. At present about 22% of milk and 2% percent of meat is processed into value-added products for trade while in developed countries it is above 90% and 60%, respectively. Traditional dairy products not only have established market in India but also great export potential because of strong presence of Indian diaspora in many part of the world. Value addition to dairy foods would provide health benefits to the consumers and improve the scale of economy in the dairy industry. Nearly half of the milk produced in India (50-55%) is utilized for the manufacture of value-added milk products but only 22% of the total milk produced is processed by the organized dairy sector. Conversion of surplus milk into indigenous milk products in and around production areas is least expensive and more profitable. Most of the animal farming activities such as cleaning of barn, washing of animals and hygienic maintenance, fodder collection, feeding, watering, and health care, management, milking, collection of dung for fertilizer and fuel, care of sick, pregnant and lactating animals, milking, household-level processing and value addition (ghee, curd, khoa, lassi and desi butter-making) are undertaken by women. However adoption of value-added livestock products as an entrepreneurship is scarce activity because of lack of training and financial liberties.

Abstract

Participation of rural women and youth in beekeeping activities provides a unique opportunity to improve rural livelihood and poverty reduction. Women have explored their own niche in beekeeping industry by actively engaging in post harvesting of bee products. Income generation is one of the major reasons for participating in beekeeping activities and beekeeping was ranked number one at the same level as agriculture as major source of income. Post harvesting beekeeping, however, needs liquid capital investment which, limit women and youth to fully participate in the business. Cultural practices are also one of the main hindrances for adult women and youth to participate in beekeeping activities. Nonetheless, presence of beekeeping groups and associations, community banks, forest reserves and beekeeping awareness campaigns in the areas provided opportunities for women and youth to participate in beekeeping. Beekeeping represents one opportunity for income generation which need not be time consuming and can fit in well with women’s priority activities. women be given the opportunity to start beekeeping, it is important that all beekeeping development programs ensure from the outset that extension messages reach rural women, and that they are able to take full advantage of training and credit facilities.

Abstract

Women make up almost half of the agricultural labour force in developing countries (43 per cent according to UN Women data). Empowerment of women is central to achieving the objective of inclusive, equitable and sustainable development. Between the period 2007-08 and 2009-10, the share of person-days in casual employment in MANREGS to the total person-days in all economic activities has also increased. The increase was marginal for male workers but significant for female workers. This again confirms that female workers have been the largest beneficiaries of MANREGS projects. The share of female participation in these public works is more than the share of their male counterparts. The survey shows that women comprise only 13.76% of the total entrepreneurs, i.e., 8.05 million out of the 58.5 million entrepreneurs. Among the states, the largest share in number of establishments under women entrepreneurship is of Tamil Nadu (13.51%) followed by Kerala (11.35%), Andhra Pradesh (10.56%), West Bengal (10.33%) and Maharashtra (8.25%). Average employment per establishment for women owned establishments is 1.67. The main challenges that women face in business are educational and work background, balancing their time share between work and family, problems of raising start-up capital, difficulty in borrowing fund, thought-cut completions endangered existence of small companies, problems of availing raw- materials access to export market without intermediaries, as well as an overall psychological barrier on the part of banks, suppliers, and clients alike. Govt of India and different bodies such as NGOs, voluntary organizations, self-help groups, institutions and individual enterprises from rural and urban areas are active to help the women entrepreneurs in their ventures.

Abstract

Women in India constitute a larger proportion of total unemployed population and hence it is imperative to find out the entrepreneurial problems faced by them. A study was conducted with the objectives to ascertain the financial, marketing and production problems faced by women in their enterprises and assessment of their health status and work place facilities. Boutiques, beauty parlors, embroidery units, fruit and vegetable preservation units and artificial jewelry making were the enterprises selected for study. The results of the study revealed that women faced problems in areas like finance, marketing, health, work place and production. Some recommendations of the study are a) Women entrepreneurs should keep abreast of knowledge about new techniques, financial institutions, training institutions and marketing linkages. b) Information about site or location, physical facilities, transportation etc. must be collected prior to selection of area for development of an enterprise. c) Self help mutually aided groups must be formulated for overcoming common entrepreneurial problems. d) Women should shift to the non-traditional sectors of entrepreneurship in order to earn more.

Woman is an incarnation of ‘Shakti’the Goddess of Power. If she is bestowed with education, world’s strength will double. Let the campaign of ‘Kanya Kelavni’ be spread in every home; let the lamp of educating daughters be lit up in every heart across the regions and religions of the world.

Abstract

Globalization defines a new process of economic integration which is fuelled by neoliberal ideals claiming that an unregulated market economy maximizes economic efficiency and growth. Concept of equability and women empowerment provides durable strength and sustainable development to the programs aimed at promotion of commerce and trade through globalization. The post 2015 Development Agenda have not done much to address the large inequalities and discrimination against women. Global initiatives designed to benefit the daily lives of women and girls not being implemented effectively. This is especially for decision making and financial systems. The right to women needs to be ensured in order: to participate in the elaboration and implementation of development planning at all levels, to have access to adequate health care facilities, including information, counselling and services in family planning, to benefit directly from social security programmes, to obtain all types of training and education, formal and informal. All forms of discrimination against all women and girls everywhere must be ended. Out of the seventeen sustainable development goals (SDGs), not even the single one will be achieved without including women and girls as equal partners. All countries hold the same responsibility to ensure the full implementation of the 2030 Agenda for Sustainable Development within their own borders, and to support other countries in achieving the SDGs which includes reaffirming and contributing to the fulfilment of gender equality. Women and girls have to be equal partners in sustainable development.

Abstract

Gender Budgeting was first introduced in 1985 and is being implemented globally by more than 50 countries to ensure gender equality goals. India took initial steps towards analysing the gender gap through “Towards Equality” a Report of the Committee on the Status of Women by the Government of India in 1974. Gender based resource allocation in the country was seen from 1990s onwards in the Eighth Five Year Plan (1992-97) when for the first time gender perspective and the need to ensure definite flow of funds from general developmental sectors to women was emphasised upon. Women constitute 49% of human population in India so it is extremely important that the untapped gender potential is recognized, reorganised and utilized efficiently & effectively to attain a leading position in S&T sector. India has expanded her R&D base immensely since the turn of the 21^st century. Consequently there has been 10 times enhancement in enrolment of women in S&T disciplines in institutions of higher education since 1989-90. Department of Science and Technology has taken many steps in recent past to strengthen the ecosystem to empower women in S&T domain, particularly by enabling over 4000 of them who had a break in career, primarily due to familial responsibilities, to make a dignified comeback. Several Role Models, who have shown their mettle and made a mark in the chosen field, are emerging and engaging & encouraging the young, Gen Next girls.

Abstract

Beekeeping or modern apiculture is the art and science of rearing, breeding and managing honey bee colonies in artificial hives for economic benefits. Beekeeping has evolved into a farming enterprise that involves the use of sophisticated and artificial techniques to keep honey bees for bee products. It is estimated that beekeeping is practiced in about four lakh villages and provide employment to over 3.50 lakh persons. The existing vegetation wealth of India can sustain six million bee colonies which would produce six lakh metric tonnes of honey besides generating part time employment to more than 15 million rural and tribal households. Rural women have long working hours, spent on food production and processing and/or waged labour, in addition to family care and domestic duties. However, beekeeping represents one opportunity for income generation which need not be time consuming and can fit in well with women’s priority activities. Population, female (% of total) in India was reported at 48.18 % in 2017, according to the World Bank collection of development indicators. Rural population (% of total population) was reported at 66.46 % (83.3 crore) in 2017 as compared to urban population (37.7 crore). There are fewer women than men beekeepers, but women beekeepers are found throughout the developing countries of every continent. Participation of rural women and youth in beekeeping activities provides a unique opportunity to improve rural livelihood and hence poverty reduction. Beekeeping as an agro-industry presents tremendous potential and requires attention on part of planners, policy makers, development agencies and researchers on the one hand and wider publicity about the commercial and scientific uses of beekeeping products on the other. In order to increase income accrued from beekeeping activities, promoting and support of training on processing of secondary bee products to women and youth beekeepers are important. Stakeholder’s involvement in promoting and support beekeeping awareness campaigns is crucial to enhance the contribution of the sector for livelihood improvement and environmental conservation.

Abstract

Women empowerment means capacity of womenfolk to participate as equal partners in cultural, social, economic and political systems with much appreciated and gladly accepted by the society. Acceptance of unequal gender norms by women are still persisting in the society. Moreover, ignorance prevails in rural areas and subordination to men is considered as god-will by the womenfolk. Food, health and education are prioritized to boys and girls’ destiny is linked to surplus resource of the family if any, available. Gender inequality exists in every nation on the planet. Women’s disempowerment is all over the world, comprising countries of east and west so empowerment of women has become one of the most important concerns of 21st century’s world. More than one third of the world’s adults, most of them women, have no access to printed knowledge, to new skills or to technologies that would improve the quality of their lives and help them shape and adapt to social and economic change. There are 130 million children who are not enrolled in primary school and 70 per cent of them are girls. Women and girls around the world are more likely to live in poverty due to discriminatory and unjust economic policies, pervasive gender inequality, war and instability and climate change. Human society has to work for sexual and reproductive health and rights, freedom from violence, economic justice, and leadership as these are the critical building blocks for women’s rights. When a woman has these rights, she can be strong, safe, powerful, and heard. Cultural and religious factors are hurdles to women empowerment so the greatest need of the hour is to change the social attitude towards women. There is need to envision a world where all women, girls, and trans people have a voice and choice in the work they do. They are paid equal wages in safe and secure workplaces and they have access to justice and rights. Strengthening women’s leadership should be priority area because it is an integral part of social perception towards women status. The future of women’s human rights depends on a strong pipeline of diverse young women leaders, as well as on creating opportunities for leaders from different generations and movements to learn from each other. Long lists of international and national initiatives are available on the websites of various governments and United Nations but the tangible results are still awaited mainly because of poor/ half heartedly implementation.

Abstract

World Economic forum (WEF) which evaluated 149 countries on four parameters including economic participation and opportunity, educational attainment, health and survival, and political empowerment, said that it would take 108 years to close the overall gender gap. That means the economic opportunity gap-based on participation, pay and advancement in the workforce-remains the area that is going to take the longest time to close. Globally, women are paid less than men. Women in most countries earn on average only 60 to 75 per cent of men’s wages. Contributing factors include the fact that women are more likely to be wage workers and unpaid family workers; that women are more likely to engage in low-productivity activities and to work in the informal sector, with less mobility to the formal sector than men. India’s inequality crisis hurts girls and women the most. An Oxfam report on inequality published in January 2019 revealed that in the workplace, women still receive 34% less wages than their male counterparts for the same work. In J&K, incidences of domestic violence, dowry, etc are rampant. State Women Commission J&K receives 1600-1700 domestic violence cases every year, majority cases being from the Kashmir Valley. Men’s silence, insensitivity and indifferences with regards to gender equality practices need to be the focus theme of the time. The fight for gender equality cannot be fought by women alone. Men have a key role to play in demanding and supporting this societal shift by being a part of the movement.

Keywords: Women empowerment, global perspectives, Indian perspectives, way forward.

Abstract

Political participation of women, on equal terms with men, at all levels of decision-making is essential to achieve the principles of equality, sustainable development, peace and prosperity. Participation is a development approach, which comprises the involvement of disadvantage segments of population in the design and implementation of policies concerning their wellbeing. To achieve gender equality by 2030 requires urgent action to eliminate the many root causes of discrimination that still curtail women’s rights in private and public spheres. Discriminatory laws need to be changed and legislation adopted to proactively advance equality. 49 countries still lack laws protecting women from domestic violence, while 39 bar equal inheritance rights for daughters and sons. Based on data from 87 countries, 1 in 5 women and girls under the age of 50 will have experienced physical and/or sexual violence by an intimate partner within the last 12 months. International efforts through UN are being encouraged throughout the world but are constrained by lack of national policy, cultural factors, social factors, religious factors, economical factors and role of gender base patriarchy. Secular and sustainable democracy prevails only when women experience benefits equally with their male counterparts. Creating adequate space in politics for women participation is essential to sustain real democracy and oblige mothers, wives, daughters and sisters and Gender Responsive Governance is the best strategy for this which embodies measures, attitudes and practices of different stakeholders, both men and women, at different levels of governance with a clear purpose to impact issues that foster women’s empowerment and promote gender equity and social justice. It is a process that promotes and sustains the ability of women to fully participate in the governance and development process, enhances their ability to raise critical questions about inequality and violence against them without fear and pressure.

Maps make it easier to interpret and communicate the results of any GIS analysis. R has a large number of packages for making thematic maps. Static mapping is straightforward with plot()methods provided by core spatial packages sf and raster. The use of plot() function have been discussed in the previous chapters. Another package for mapping isspwithspplot() having enough options for producing good quality thematic maps.It is also possible to create advanced maps using ggplot2. This chapter discusses, separately, preparing thematic maps from vectors and rasters with the above mentioned packages. A dedicated map-making package tmaphas been given special focus in this chapter.

Elevation or height data of land surface above a defined vertical datum is stored in the form of raster grids which is known as Digital Elevation Model (DEM). The DEM data can be processed to derive many useful parameters like slope, aspect, curvature, roughness, etc. This process of quantitatively describing terrain obtained from DEM data through computation of many variables is known as Digital Terrain Analysis. Digital terrain analysis has applications in the various fields like hydrology, ecology, geomorphology, etc. DEM data for digital terrain analysis are available from the satellites like ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer), Cartosat, ALOS (Advanced Land Observation Satellite), and SRTM (Shuttle Radar Topography Mission).

In this exercise, we are going to discuss the derivation of some primary and secondary terrain attributes from DEM data in R software. For performing digital terrain analysis in R, following packages are required.

Supervised classification is the technique to classify raster image in which prior information about the classes in the form of training sites is provided by the user. Training site represents a homogeneous area in a particular class. The spectral response pattern of training sites is used to classify the raster image.The pixels of raster imagewhich have spectral response pattern similar to that of training sites of a particular class are grouped in that class. As there is some variability in the spectral response pattern of a particular class, therefore, multiple training sites per class are taken for supervised classification. Supervised classification of raster images can be performed by various methods. Conventional methods include maximum likelihood classifier, minimum distance to mean classifier, and parallelepiped classifier. Now a days, machine learning algorithms are also gaining importance in this context. These classifying algorithms are first trained or calibrated using the data of training sites.This trained model is then validated on the independent datasets for accuracy assessment. If the accuracy of the developed model is of acceptable level, then that model is used for the classification of raster data.

In this chapter, we are going to discuss the execution of maximum likelihood classifier and few machine learning techniques for supervised classification of raster image in R software. The training sites used in this exercise are in the form of points shapefile. The raster image is classified into six classesi.e. built- up, fallow soil, riverine sand, salt-affected soil, vegetation, and water. For performing this exercise, first of all,set the working directory and import the required packages.

Unsupervised classification is the technique of classification of raster data in which no prior information is provided by the user. Raster data is classified based on their spectral characteristics such that the pixels having similar spectral properties in the multispectral feature space are grouped together in one class. Unsupervised classification is mainly performed by clustering algorithms. The purpose of these algorithms is to minimize within cluster variability and maximize between clusters variability. The user must interpret and label the classes after performing unsupervised classification. This method of classification requires minimum data which makes it easy and quick, but user has toput efforts in identification of the classes. This method could be useful when user doesn’t have any prior knowledge about the study area. This method removes subjectivity and enables us to get the unique classes which might be unrecognized by the user. K-means is the most commonly used method for performing unsupervised classification. In this chapter, we have discussed K- means, CLARA and unsupervised random forest method for classification of raster data in R.

Raster transformations involve mathematical manipulation of raster layers to generate new raster images. These transformed raster images either contain the information of interest or highlight the features which are not discernible in the original image. Transformations are also performed to preserve the essential information in reduced number of dimensions or layers. In this chapter, we are going to discuss few most commonly used transformation tools listed below:

Remote sensing images have an important characteristic known as spatial frequency. Spatial frequency is defined as the number of changes in pixel value per unit distance. Few changes in pixel or brightness value over an area in an image are known as low spatial frequency area like agricultural fields, forests, water bodies, etc. If the changes are large, then it is known as high frequency area like roads, built up areas, etc. Spatial filtering is an approach for extracting quantitative spatial information by taking into account the neighbouring pixel values along with the independent pixel value. Therefore, filtering is a technique for modifying or enhancing an image. Filtering is done to improve the interpretability of raster image or to extract certain information from them. It is a neighbourhood operation because the value of any pixel in the output image is determined by applying certain algorithm on the neighbourhood pixels of the corresponding input pixel. The nature of algorithm to be applied depends upon the information which user wants to derive from the raster image. Filtering operations are mainly done for smoothening, sharpening, noise removal and edge enhancement. A filter is a kernel of small array which is applied to input pixel and its neighbouring pixels in the raster. There are many types of filters which can be applied to a raster image in R. These types with their respective R – code examples are explained further.

The sensors present over remote sensing satellites are designed to collect energy or radiance from the varied surface features having wide range of radiance i.e. from features like water bodies having very low radiance to features like sand or snow having very high radiance. But, most of the time, the study area may not have all these features; therefore, radiance values may remain confined to a narrow range. This reduces the contrast of the image, thereby decreases its visual quality. In this context, image contrast enhancement techniques are used for effective visualization and display of remote sensing image on computer screens or hard copy so that maximum amount of information can be derived through its visual interpretation.

Contrast enhancement of a digital image is a technique to modify the original grey levels of input image to the entire available range of the grey levels. This increases the contrast between various features in the image which improves the visual quality of original image. Contrast enhancement can be done by both linear and non-linear methods. Some of the commonly used contrast enhancement techniques with their implementation in R software are discussed in this chapter.

We need following packages for performing this exercise in R. raster package is required for importing of raster image and for performing contrast enhancement. RStoolbox package is also required for contrast enhancement as well as for visualization of raster data with ggplot2 package. rasterVis package is mainly used in this exercise for plotting histogram of the raster data.

The calculation of raster data statistics is very essential before performing some geoprocessing operations. Raster data statistics involve knowing the distribution of pixel values in a band, comparing the pixel values of two bands, extracting values of all bands for a particular geographical location or point, and computing statistics like mean, median, standard deviation, etc. at pixel level across all bands of raster dataset.

In R, codes to perform raster data statistics are present in raster package. The visualisation of raster data statistics can be done by rasterVis package. So, we need to import these packages in R in order to perform this exercise.

Many times, users have to work with raster datasets of different spatial and radiometric resolutions. So, there is requirement of bringing their resolutions to the same resolution in order to facilitate their processing. Resampling is the process of deriving pixel values from the existing image to the new raster image of different pixel size. Resampling is most common pre-processing step in remote sensing. It is done both at spatial and radiometric scale. At spatial scale, resampling is done either to increase the spatial resolution i.e. decrease pixel size known as Upsampling or to decrease the spatial resolution i.e. increase pixel size known as Downsampling. Radiometric resampling is performed to increase or decrease the radiometric resolution of the image. In R, resampling of raster image is performed by raster package. The details of the resampling methods and their respective R – code with examples are discussed in this chapter.

First of all, we need to import the raster image on which we wish to perform resampling operations by using following R – code. In R, resampling is feasible on one band only. So, we will import single band raster image.

Mosaic is the combination of two or more raster images into single image. Sometimes, single image captured by remote sensing satellite doesn’t completely covers the desired study area mostly. Therefore, users resort for mosaicking two or more images captured by satellite sensors from different paths so that the whole study area is merged into a single raster image to facilitate the image processing and analysis. The pixel size of the raster images should be same for mosaicking.

In most of the cases, there is spatial overlapping among the raster images from which we want to create mosaic. These overlapping areas are handled in multiple ways which is being discussed further using R – code example. For mosaicking raster images in R, mosaic function of the raster package is used.

Vector data analysis is performed to convert raw input vector data to output that provides new and meaningful information which ultimately supports decision making and disclose hidden patterns. There are various techniques to analyse vector data like buffering, intersect, union, and so on. Some of the most commonly used techniques with their R-code examples are explained in this chapter.

First of all, you need to import all the packages which are required for performing this exercise. These packages include rgdal and sp for importing and re-projecting vector data as well as raster and rgeos for performing vector analysis operations.

Raster sub-setting is done to select the desired area or bands of the raster image on which the user wants to perform analysis. Raster sub-setting is done in two ways:

Spectral subset: Spectral sub-setting is done to extract few desired bands from the multiband raster image which are required for analysis.

Spatial subset: Spatial sub-setting is done to minimize the area or extent of raster image to the desired area or extent for further analysis.

Raster sub-setting in R is done by functions available in the ‘raster’ package. The following packages are required in this chapter:

Coordinate Reference System (CRS) is a framework of coordinate based local, regional or global reference system used to represent the locations of geographic features. Coordinate Reference Systems (CRS) provide a standardized way to define the real-world geographic locations which further enable us to use common locations of geographic datasets for integration. The datasets from different sources and CRS are transformed to a common CRS in order to perform various integrated analytical operations like overlaying of data layers. Coordinate Reference Systems are mainly of two types:

1. Geographic Coordinate System: This is global or spherical coordinate system in which locations of features on earth are defined in terms of latitude and longitude values. Latitude and longitude are angles based on a point at the centre of the earth. In this system, locations are defined by degrees, therefore, distances cannot be measured accurately. The most common geographic coordinate system is the World Geodetic System 84 (WGS84).
2. Projected Coordinate System: In this system, locations of features are defined using cartesian x, y coordinates on a flat, two – dimensional surface. This system is based on sphere or ellipsoid projected on flat surface. Projected Coordinate System are generally referred as projec- tion. It is required for preparing maps on paper or computer screen. Un- like Geographic Coordinate System, projected coordinate system has ac- curate measurements of distance, angles and areas across the two dimen- sions. However, there is alwaystrade-offs between area, direction, shape, and distance in this system due to distortions created while representing ellipsoid or spheroid on a flat map. So, the projection type is selected based on its application. Most common projections are Universal Trans- verse Mercator (UTM), Lambert Conformal Conic and Albers Equal Area.

Vector data consists of points, lines and polygons with x, y coordinates known as vertices representing the geographic location i.e. latitude and longitude. Vector data depicts the shape of the spatial feature. Points consist of single x, y locations. Examples of points are tower location, sampling location, etc. Lines represent 1 – dimensional features like roads, streams, etc., and are composed of many or at least two connected points or vertices. Polygons denote 2 – dimensional features like boundaries with three or more vertices that are connected and closed. The vector data are represented in the following figure (fig. 5.1).

Sensors onboard the satellite records the intensity of emitted or reflected electromagnetic radiations in the form of digital number (DN) for each pixel. These digital numbers can be transformed to more meaningful intensity units like radiance or reflectance. This process of conversion of digital numbers to radiance or reflectance is known as radiometric calibration. Sensor specific information is required to conduct radiometric calibration.

The satellite data is available in raster format. Raster data consists of two – dimensional array of pixels or grids which stores the values representing features. All the pixels are of same size and shape with their particular coordinate location. A raster data format is shown below.

2.1. Open source satellite data

The satellite images have been invaluable information sources for Natural Resource Management. They provide synoptic view of the Earth periodically helping in inventory, surveying, and monitoring in agriculture, hydrology, geology, mineralogy, land cover, land use and environment. Free global satellite image data of spatial resolutions of 1m to 1 km and spectral resolution of single band to hyperspectral are available from an increasing number of sources (Table 2.1).

1.1 R and R studio

R has become the world-wide language for statistics, predictive analytics, and data visualization. R is not limited to statistics; it has a wide range of tools for spatial analysis and digital image analysis and can handle any process needed for image analysis flexibly. It offers a wide range of methodologies for digital image processing, from the most basic to the most complex. As an open source project, it’s freely available for a range of platforms, including Windows, Mac OS X, and Linux. An integrated development environment (IDE) for R, R Studio, allows interactive execution of R functions with user interface. RStudio is available in two formats - RStudio Desktop and RStudio Server - both available in free and fee-based (commercial) editions.

1.1.1. Download and install R

The R software setup files can be downloaded from any of the widely distributed Comprehensive R Archive Network (CRAN). To download R, please choose your preferred CRAN mirror, a location close to you. Follow the following steps:
