The societal implications of nanotechnology are the potential benefits and challenges that the introduction of novelnanotechnological devices and materials may hold for society and human interaction. The term is sometimes expanded to also include nanotechnology’s health and environmental implications, but this article will only consider the social and political implications of nanotechnology.

As nanotechnology is an emerging field andmostof its applications are still speculative, there is much debate about what positive and negative effects that nanotechnology might have.

Beyond the toxicity risks to human health and the environment which are associated with first-generation nanomaterials, nanotechnology has broader societal implications and poses broader social challenges. Social scientistshave suggestedthatnanotechnology’s social issues should be understood and assessed not simply as “downstream” risks or impacts. Rather, the challenges should be factored into “upstream” research and decision making in order to ensure technology development that meets social objectives.

All scientists working with laboratory animals must have a deep ethical consideration for the animals they are dealing with. From the ethical point of view it is important that such considerations are taken care at the individual level, at Institutional level and finally at the national level.

Individually each investigator has an obligation to abide by all the ethical guidelines laid down in this regard at institutional level. The Head of the institution, maintaining animals for scientific experiments , should constitute an animal ethics committee on animal experimentation to ensure that all experiments conducted on animals are rational , do not cause undue pain or suffering to the animals and only minimum number of animals are used. The constitution and term of reference of the animal ethic committee should be well defined.

An animal ethic committee should include: a senior biological scientist of the institute, two scientists from different biological disciplines, a veterinarian involved in care of animals, the scientist in charge of animal facility, a scientist from outside the institute & a nonscientific socially aware member. A specialist may be co-opted while reviewing special projects using hazardous agents such as radioactive substance and deadly micro-organisms etc. The investigator may be called in for any clarification if required.

The ethics committee has to examine all projects involving use of animals before implementation, to ensure that minimum number of animals is used in the project and the ethical guidelines are strictly adhered to. It will also examine that the scientists and technicians handling animals possess adequate skill to perform the experiment. All animals should be maintained under standard living conditions and experiments will be conducted under proper anesthesia and termination of an experiment, the animal will be humanely sacrificed under anesthesia. Before disposal it must be ensured that the animal is clinically dead.

Introduction

The past decade has witnessed a revolution in the use of ICT in Developing countries. Many people and offices as well as rural farmers own ICT facilities such as personal computers and mobile phones. The largest increases in the use of ICT has been in mobile telephony where subscriptions in developing countries increased from about 30 percent of the world total in 2000 to more than 50 percent in 2004 and to almost 70 percent in 2007 (Cieslikowsk, Halewood, Kimura, & Zhen-Wei Qiang, 2009). While internet use has not increased as rapidly as mobile communication, it increased tenfold in developing countries in the same period (Cieslikowsk et al., 2009). Other ICT facilities such as telecast, radio FM and information centres have also increased in number remarkably during the same period. A study by Farrell & Isaacs, (2009) on ICT in 53 African countries revealed the wide use of ICT in the region with countries such as Algeria, Egypt, South Africa and Botswana leading in ICT use. In East Africa, Rwanda is probably the most advanced country in terms of ICT use with 65% of its population being covered by mobile telephony. The country has also a high level of internet use and access to television and radio broadcasts. In Kenya, Uganda and Burundi the use of ICT is also well advanced, especially for mobile phone subscribers, TV and radio listeners (Farrell & Isaacs, (2009). This high use of ICT is likely to stimulate economic development in developing countries, including the agricultural sector where a high proportion of the African population derives their livelihoods. Before 1990, ICT use in Tanzania was mainly limited to radio and landline telephones. New ICT started in the mid-1990s, and by 2001 it was estimated that Tanzania’s ICT industry had generated USD 300-350 million per year. There are now a number of ICT development initiatives in the country funded by the government, donor countries and the private sector. Such initiatives range from telecentres and mobile phones in rural Tanzania to e-Government initiatives being implemented in the major cities and towns of Tanzania.

2.0. What is Tense

A tense can be defined as the form of a verb that indicates the time and the state of an action or event or Tense is the study of forms of verbs.

India is a geologically diverse country with a wide variety of rock types. The major rock types found in India can be broadly classified into the following categories:

Igneous Rocks: These rocks are formed from the solidification of molten magma. They can be further divided into two types:

1. Plutonic (Intrusive) Igneous Rocks: Examples include granite, diorite, and gabbro. These rocks are formed deep within the Earth's crust and have a coarse-grained texture.
2. Volcanic (Extrusive) Igneous Rocks: Examples include basalt, andesite, and rhyolite. These rocks are formed on the Earth's surface from volcanic eruptions and have a fine-grained texture.

Sedimentary Rocks: These rocks are formed by the deposition and consolidation of sediments over time. They can be further divided into various types based on their composition and mode of formation:

1. Clastic Sedimentary Rocks: Examples include sandstone, shale, and conglomerate. These rocks are formed from the accumulation and lithification of fragments of pre-existing rocks.
2. Chemical Sedimentary Rocks: Examples include limestone, dolomite, and rock salt. These rocks are formed from the precipitation of minerals from water bodies.

The one-day SCSP-training program on “Opportunities for fish farmer producer companies and government schemes for fisheries stockholders” was organised by Shashwat Sheti Vikas Pratishthan, Shivajinagar, Pune, Maharastra, on 4 January 2022. The training programme was sponsored by MANAGE, Hyderabad. 50 people participated in the training program, consisting of agrifarmers, fishermen and unemployed youths. Out of the 50 participants, 19 were women and 31 were men.

The session is all about FPO formation MANAGE organised a training programme to sensitise farmers about Farmer Producer Organizations (FPOs) and various schemes under PMMSY. FPOs can help farmers take advantage of economies of scale in production and marketing, and the government’s plan to establish 10,000 new FPOs by 2024 is a step in the right direction. It is while social media is a powerful tool for spreading information quickly, not everyone has access to it, especially in rural areas. So, training programmes like this can be very effective in reaching out to farmers and providing them with the information they need to make informed decisions about their farming practices.

Roots are
well known for anthelmintic,anti-diuretic and anti-inflammatory properties. Decoction of the root used against heart diseases, rheumatism, asthma and piles. Pseudarthria viscida is becoming extinct from nature, and its number has been reduced drastically. Due to the limited availability of Pseudarthria viscida, which is substituted by other leguminous trifoliate plant species such as Desmodiumpulchellum and Uraria rufescens. There for, it is put in the red list category and the plant requires proper management practices to exploit its therapeutic potential in the treatment of various diseases.

Livestock integration into a farming system offers multiple benefits, including manure for soil fertility, animal products for food and income, and utilization of crop residues. Livestock components like dairy, piggery, goatry, poultry, and duckry are essential for enhancing income, improving livelihoods, and ensuring sustainability within farming systems. They are particularly important in diversified and integrated farming approaches, enabling
multi-output farming that benefits rural communities both economically and nutritionally. Livestock plays a vital role in farming systems across India and serves as a major source of livelihood, especially for small and marginal
farmers. It provides nutrition, income, employment, and farm inputs such as manure and draft power, while also serving as a risk buffer in times of crop failure.
• Dairy: Dairy farming involves the rearing of cows and buffaloes for milk production. It is a prominent source of regular income in rural areas and supports food security through milk and milk products. Cow dung is also used as organic manure and fuel.
º Definition: Raising cattle (cows, buffaloes) primarily for milkproduction. 

ABSTRACT

Human resources are one of the most strategic and critical determinants of growth. A country cannot make rapid social and economic advancement unless it has enterprising people with necessary knowledge, skill and attitudes. Entrepreneurship development not only helps individual to become self reliant but also adds to wealth creation process, thereby paving the way to past growth and development of the nation. Rural entrepreneurship is required to capitalize on the opportunities available and to create job, mainly for rural youth and the farm family. In order to achieve this we are promoting mushroom production and processing as an enterprise for rural youths and farm family through their capacity building activities like training, consultancy, forward and backward linkages and to some extent by making available the much required inputs in the initial stages as the scenario of mushroom production in state is far from satisfactory. With the vast opportunities both at the international and national levels lying at the door steps of India, nothing less than a mushroom revolution in the coming decade will help to achieve the targets of nutritional security of people. During last year we have trained 215 farmwomen and youth in mushroom production and processing out of which 110 trainees started producing it at small scale and selling in the local market. Three villages of Patna district have been developed as “mushroom village” namely Sadikpur, Chaknawada and Mahmadpur. A sample of 100 mushroom growers of Patna district was taken for present investigation. All of them agreed that growing mushroom is a beneficial enterprise as it is capable of recycling agricultural wastes and generating employment opportunities. But, they revealed that important constraints in recommended practices of mushroom cultivation are spawn availability, perishable nature and marketing of mushroom in local villages because of poor infrastructural facility and lack of institutional finance available to them. So, in order to encourage mushroom Production at household level in villages, it is required to uplift farmers, initiating new applications, providing them with adequate marketing information and sufficient agri-business finance knowledge. Two of the most important problems in India, unemployment and malnutrition, will be addressed to a larger extent by promoting the cause of mushroom growing and its utilization as health food.

Mamata Banerjee has raised the important issue of land use and acquisition for public, political, professional and media debate. With increasing population pressure on land, this issue deserves careful consideration and rational discussion. The Singur dilemma in a wider sense relates to both land use policy and norms of compensation for land acquired by government for non-farm purposes. Land conflicts are also spreading in other parts of our country, as far example where land is needed for establishing Special Economic Zones (SEZs). The Maharashtra Government has wisely adopted the policy of holding a referendum to seek the views of farmers and others who will be dispossessed of their land for meeting the needs of SEZs. Pro-active consultations will help to avoid difficulties later. Water conflicts are also affecting important irrigation projects. Land conflicts are likely to do the same and may affect the balanced growth of the primary, secondary and tertiary sectors of the economy. How can we deal with this situation in a manner which leads to a win-win outcome for all the stakeholders ?

Artificial insemination in horses is being practiced since many years in Russia and China for genetic up-gradation. The equine artificial insemination industry has evolved a system in which mares are inseminated with fresh or cooled semen (500 million motile sperm) every 48 hours until estrus is no longer detected or until ovulation is detected by trans-rectal palpation or ultrasonography of ovaries respectively. The advantages of AI include:

Cotton (Gossypium) seed meal (CSM), the by-product of cotton seed oil industry, is widely used as an animal feed. However, its utilization as an animal feed is limited due to the presence of gossypol, a polyphenolie binaphthyl aldyde, which is toxic to non-ruminants such as poultry and swine and young ruminants such as calves and lambs. The gossypol (free gossypol, FG) present primarily in the pigment glands of cotton seed, is mostly converted to bound gossypol due to condensation of aldehyde group with free amino groups of proteins to form a schiff base. Formation of schiff base though results in the detoxification of gossypol to some extent, it also lowers the nutritive value by reducing the availability of lysine, the limiting amino acid of cotton seed. Thus, bound gossypol, consequently total gossypol (TG) (free plus bound) content is an important factor of cotton seed meal.

The experimental design and analysis discussed in previous chapters refer essentially to experiments on annual crops. Even when these experiments are repeated in different years, this is done at a new site each year .The use of new crop production practices will generally change the important physical and biological factors of the environment. This process of change can take many years. Generally, the productivity of some types of technology must be evaluated by a series of trials repeated over time. Such trials are generally referred to as long-term experiments. Long-term experiments are those which are continued on the same set of plots over a series of years with a pre-planned sequence of treatments or crops or both. Treatments may be applied every year or periodically. The same crop may be repeated year after year or once planted may continue for several years as perennial trees ,or a sequence of crops may be grown in rotation as for instance rice-rice or rice-wheat (1 year sequence with 2 crops per year ) or sorghum,groundnut,cotton and wheat, each crop cycle being completed in four years. The main features of long-term experiments are as follows :

Speculation and hedging are important ways of minimizing price risk in business.

Speculation: Risk is taken by person specializing in business without much consideration of business trends.

Hedging: A calculated risk is taken.

KVK Ramkrishna Ashram in Kolkata undertook a 5-day SCSP (Schedule Class Sub-Plan) training programme from MANAGE, Hyderabad, to develop integrated farming practices and encourage young people to choose farming as a career. West Bengal’s status as the highest fish producing state in India and its leadership in fish seed production present a significant opportunity for farmers and entrepreneurs in the fishery sector. Fish is widely consumed throughout the nation, especially in West Bengal, where it is estimated that each person consumes 15.6 kg of fish per year, compared to India’s average of 9.0 kg. It is regarded as a major source of essential micronutrients and the primary source of animal protein. By leveraging smart farming solutions enabled by technology, farmers can increase their productivity and income, while also meeting the demand for fish and essential micronutrients in the region. The training programme could play a vital role in empowering farmers and entrepreneurs in the state to adopt innovative and sustainable farming practices and make the most of these opportunities.

These three components—horticultural crops, agroforestry systems, and aquaculture—play a significant role in diversifying agriculture, increasing income, and promoting sustainability in farming-based livelihood systems
across India. Horticultural crops, agroforestry systems, aquaculture, duck/ poultry cum fish, and dairy cum - all describe different farming systems, often with a focus on integration and diversification. Here’s a breakdown of each: • Horticultural Crops: This refers to the cultivation of fruits, vegetables, flowers, and ornamental plants. It’s a broad category encompassing many different specific crops and growing techniques. Horticulture includes the cultivation of fruits, vegetables, flowers, spices, condiments, and medicinal plants. These crops are high-value, laborintensive, and contribute significantly to nutritional security, income generation, and employment creation, especially for smallholders and women. Examples: Mango, banana, guava, brinjal, tomato, onion, rose, marigold, turmeric.
Advantages
• High market demand and export potential.
• Year-round employment opportunities.
• Improves diet diversity and nutrition.
