Sustainability

Sustainability is a complicated concept. The most often cited definition comes from the U.N. World Commission on Environment and Development (WCED): “Sustainable development is the development that fulfills the needs of the present without compromising the ability of future generations to meet their requirements.” Hence, sustainability has been defined as meeting our own needs without compromising the ability of future generations to meet their own needs.

Commercial Building

Commercial buildings consist of government buildings, banks, hospitals, schools, malls, retail, restaurants, and office spaces. Among these, office and retail occupy the major percentage of energy consumption. 

More than 40% of the total final energy consumption and about 30% of greenhouse gas (GHG) emissions are in connection with the civil and residential sector.

Maximum energy consumption in commercial buildings by HVAC system (51% followed by appliances and food service equipment (20%), lighting(12%), electronics and information technology(9%) and water (8%).

Introduction

India has vast livestock resources. Livestock sector includes animal husbandry, dairy and fisheries sector. Livestock provides livelihood to two-third of rural community and employment to about 8.8 % of the population in India. Livestock sector contributes 4.11% GDP and 25.6% of total Agriculture GDP. It provides milk and milk products, meat and meat products, and also constitutes a major supplier of food and food articles, raw materials, and finished products.

Introduction

To address the escalating food demands of the global population, a transformation in the agricultural sector is imperative (Velten et al., 2015; Lampridi et al., 2019). The current overdependence on finite resources is leading to their overexploitation, largely due to irresponsible usage (Velten et al., 2015; Lampridi et al., 2019). By adopting a site-specific approach, farmers can apply inputs only where they are necessary in the field (Velten et al., 2015; Lampridi et al., 2019). This method can enhance output, decrease labor costs, and mitigate the environmental damage caused by excessive input use (Velten et al., 2015; Lampridi et al., 2019).

Climate change impacts

• Climate change is a crucial factor behind cyclone Tauktae

• Global ocean has absorbed 90% of the excess heat generated by greenhouse gas emissions since 1970

• Led to anomalous ocean warming in Arabian Sea and Bay of Bengal, which in turn makes cyclones intensify rapidly

• India will see more frequent cyclones every year due to global warming

Climate change is altering insect-pest development, reproduction, feeding, survival, distribution, host preference and interactions with natural enemies. These shifts may make conventional control measures and existing integrated pest-management programmes less reliable. Climate-resilient IPM must therefore combine continuous pest surveillance, forecasting, biological control, resistant cultivars, cultural practices, habitat management and the careful use of pesticides. Management decisions should account for changing pest phenology, emerging invasive species and regional climate risks. This chapter examines how climate change affects established IPM components and proposes adaptive, knowledge-based approaches for sustainable pest suppression, reduced pesticide dependence, ecosystem protection and long-term food security.

Lithological interpretation of igneous rocks involves the identification and description of the different types of rocks that form as a result of the cooling and solidification of magma or lava. Igneous rocks can be classified based on their mineral composition, texture, and the way they formed. Here are some of the common types of igneous rocks and their characteristics:

1. Basalt

Basalt is a dark-colored, fine-grained rock that forms from the rapid cooling of lava. It is typically composed of minerals such as pyroxene, plagioclase feldspar, and olivine.

Basalt is a common extrusive igneous rock formed from the rapid cooling of basaltic lava. It is typically dark in color, ranging from black to dark gray, and has a fine-grained texture. Basalt is composed mainly of plagioclase and pyroxene minerals, with smaller amounts of olivine, magnetite, and other minerals.

Basalt is found in many parts of the world, including the oceanic crust, volcanic islands, and some continental regions. It is also used as a construction material, such as in road paving, because of its durability and resistance to weathering. Additionally, basalt fiber is used in various applications, including reinforcing materials in composites, insulation, and other industrial uses.

Basalt in India: Basalt is a type of igneous rock that is commonly found in India. It is a dark-colored, fine-grained rock that is rich in iron and magnesium minerals.

Introduction

Eco-friendly interior design is an important consideration for anyone who wants to create a healthy, sustainable, and beautiful space.

Environmental impact: The materials used in interior design can have a significant impact on the environment. Eco-friendly materials are made from renewable resources, reduce waste, and often have a lower carbon footprint than traditional materials.

What is A Smart Energy Home?

Smart homes use internet - connected devices to enable remote monitoring and management of appliances and systems, such as temperature, lighting, and security cameras. Smart energy homes take a step beyond the gadget-filled smart home to focus on bringing smart functionality to major household energy-using systems like HVAC, water heating, and plug loads (including appliances and electronics).

Introduction on Climate Smart Agriculture (CSA)

Extreme weather conditions like rainstorms, high wind pressures, high temperatures, flood and drought situations have profound influence on agriculture. Climate and agriculture are strongly interrelated universal processes and thus variations in climate influence agricultural activities (IPCC, 2007). The effects of climate change are seen in form of global warming, unseasonal and excess rainfall, and frequent natural calamities which affects agricultural production. At the same time emission of GHG to the atmosphere is a major source of climate change. The impact of climate change on crop yield, dairy and other livestock production including fishery will be felt in reduced production and consumption. Climate change will effect in additional increase in prices for main agricultural food crops such as rice, wheat, corn and soybeans (IFPRI, 2009).

Need for climate-smart agriculture strategy

Climate change has long-lasting and potentially detrimental consequences on the agriculture sector. Changes in weather events cause perturbations across agricultural ecosystems and have impact on farm productivity. Adopting the climate-smart agriculture approach has thus, become inevitable in order to build resilience in agriculture systems and cope up with climate change. With a view to implementing climate-smart agricultural practices to ensure climate resilience, certain broad strategies have to be adopted. The CSA approach is designed to identify and operationalize sustainable agricultural development within the explicit parameters of climate change (Climate Smart Agriculture Sourcebook.FAO.2013). It integrates the three dimensions of sustainable development (economic, social and environmental) by jointly addressing food security and climate challenges.

Agriculture and Food Security

Food security refers to a situation when people gain physical and access to enough food to meet the dietary requirements for a healthy life for all times. A household can have food security when all the members lead a hunger free life. It is estimated that nearly 800 million people in the world go to bed hungry every night. Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life (World Food Summit, 1996). This definition gives rise to four dimensions of food security: availability of food, accessibility (economically and physically), utilization (the way it is used and assimilated by the human body) and stability of these three dimensions.

Climatic Factors and Crop Growth

Crop growth depends on internal and external factors. Internal factors are mostly genetic or hereditary factors which include high yielding ability, resistance to lodging, tolerance to adverse conditions such as drought, flood and salinity, tolerance to insect pests and diseases, and grain quality. The external factors include climate, edaphic, biotic, physiographic and socio-economic factors.

Modern agriculture requires certain precise information on pattern of rainfall, temperature, occurrence of drought and flood etc. for formulating required strategy for crop production. It also requires knowledge about agro-climatic conditions of the region for deciding a planned cropping pattern. Therefore climatic classification and delineation of agro-climatic zones would be imperative for a country or state.

Climatic factors like increase in temperature, carbon dioxide (CO₂) concentration, moisture, and other factors directly or indirectly affect agriculture, which have been elaborately dealt in previous chapters. Climate change causes weather variability that may result in low production, hike in price of agricultural commodities including food grains, vegetables, fruits, meat, egg and milk. It is now realised that climate resilient agriculture (CRA) will be imperative to reduce the vulnerability of agriculture to the climate change.

Climate-smart Agriculture Practices and Indicators

Considering the three pillars of climate-smart agriculture such as productivity, adaptation and mitigation, different technologies and practices have been evolved.

The CSA practices are grouped under soil and land management, water management, crop management, livestock management, forestry, fishery & aquaculture and energy management. The World Bank Group (2016) has suggested broad indicators of CSA practices (Table 7.1; Chapter 7)

Services for CSA

Under the CSA projects and programmes, the services like supply of inputs and technology transfer through extension services are provided to the farmers. The inputs like seeds of crops are provided by the input dealers at the subsidized rate and seedlings of fruits and vegetables are provided by both private and government agencies to grow under general cultivation and poly-house cultivation technology. Similarly other services like soil testing facilities, issue of soil health cards, construction of micro-irrigation projects and rain harvesting structures are made available to farmers. Under insurance scheme, loanee farmers are supported to pay premium dues for availing crop insurance facilities. Other services like trainings at various levels, demonstrations, exposure visits, exhibitions, kisan melas, field days, monitoring and evaluation of all these activities under these programmes are provided to the farmers with collaboration of extension officers.

Climate and Agriculture

Soil, climate and water are three basic requirements of a crop to be grown in a particular region. Climate affects the temperature trends, seasons, length of the growing season, amount of sunlight and the seasonality of sunlight etc. A change in climate may cause recurrent droughts, floods and weather extremities that would affect the agricultural production, human livelihoods, health and biodiversity. The relationship between agriculture and climate is complex as it is dependent on climate and also plays a contributing role in emission of greenhouse gas (GHG). Greenhouse gases include carbon dioxide, nitrous oxide, methane, chlorofluorocarbons (CFCs), hydro-chlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), per fluorocarbons (PFCs) etc. , which play a significant role in climate change.

Weather and climate have profound influence on agriculture of a region. There are some differences between these two terms. Weather describes the state of the lower atmosphere of a place with respect to temperature, precipitation, wind direction, wind speed, humidity, cloudiness and pressure etc. over a short period of time. The short term variations over minutes to days are indicated as weather of a location. It says whether the atmosphere is hot or cold, rainy or dry, sunny or cloudy, still or cyclonic and so on usually for period of 24 hours. The weather may vary from place to place and from time to time due to difference in temperature, cloudiness, humidity, rain and other events of atmosphere. It may be sunny at one locality, but rainy at another locality.

Introduction

Thar Desert is unique both from floristic and climatic parameters. Biodiversity in this region survives on a very/ fragile ecosysytem under a highly hostile environment. Major area consists of dry undulating mass of loose sand, thus, leading to shifting sand dunes. The sandy plain is full of sand-hills with serve as low depressions where salt and soda are deposited after drying. The whole area is inhospitable and sterile. Trees are rather a few and far between (Bhandari, 2005).

The Thar Desert of western India is known for its rich and ancient culture system and traditions. The communities have long been part of the Thar Desert ecosystem and have evolved specific strategies to live in harmony with its hostile environment. Orans have remained mainstay in balancing this arid ecosystem. Man of this region has never been greedy as he is today. Orans were repositories of ancient system of gene pool conservation. But, there are unregulated encroachment on the marginal lands and over-exploitation of groundwater resources. Orans has been part and parcel of the lifestyle of the Thar Desert inhabitants. Orans are used to provide vital grazing land for livestock, water, minor forest produce, medicinal plants and green cover for the villages. They were worshipped as devbhumi. Orans preserve the endemic, endangered or threatened species, medicinal plants and wild variety of cultivars found.
