Agriculture and climate change

Climate Change and Indian Agriculture

By: Staff Reporter

Over 60 percent of India’s population depend on the agricultural sector which constitutes about 14.3 per cent of India’s gross domestic product, 2010-11, as per the Central Statistics Office, New Delhi. Despite technological interventions, about two thirds of India’s agricultural area remain rainfed and vulnerable to present day climate variability. The implications of climate change is yet not very clear, although scholars agree that global climate change will lead to greater unpredictability of weather conditions at local levels.

Asian Brown Clouds, Climate Change and Reduced Rice Harvests in India

By: Staff Reporter

Apprehensions about climate continue to rise, despite our limited ability to make precise assessments of its impact. This is partially due to the complexity of chemical and physical processes at various scales and also due to confounding factors from other changes such as air pollution.

Forestry and Climate Change

Climate Change and Indian Forests

By: Staff Reporter

An assessment of the impact of climate change on forest ecosystems in India has been attempted with the forest vulnerability index for India - worked out on the basis of forest canopy density, biodiversity and projected impact of climate change.

Urban Trees for Combating Climate Change

By: Staff Reporter

The urban environment of modern India has undergone dramatic changes predominated by concrete structures, congested commercial spaces and incessant traffic. The degeneration of living environment in urban areas has severely disrupted the balance of urban climate as tree cover is eliminated to make way for ‘development’.

Forest Carbon

By: Staff Reporter

Forests are one of the most significant reservoirs of carbon. Various global processes and anthropogenic changes are influencing the process of carbon sequestration leading to interruptions in the carbon flux. Under elevated CO2 conditions a possibility of decomposition occurring more than net primary production leading to a loss of carbon is predicted in the forest regions of India.

Fisheries and Climate Change

Marine Fisheries and Climate Change

By: Staff Reporter

The adoption of a Code of Conduct for Responsible Fisheries and Integrated Ecosystem-based Fisheries Management (FAO, 2007), will be a challenge for India considering the high poverty levels prevalent in the coastal communities involved in traditional fishing. The lack of suitable alternate income generating options for them makes these communities highly vulnerable to future changes. Thus an effort to reduce their dependence on fishing is essential.

Aquaculture in Sunderban Climate Change Adaptation

By: Staff Reporter

Climate change impact in the Sunderban ecoregion with rising sea level and accelerated coastal erosion is already evident in the Mousani Island and Namkhana, Bermajur and Sandeshkhali Blocks in the Sunderban. This is increasingly disrupting the production processes and the livelihoods of communities. It is thus essential to pave way for sustainable aquaculture practices that may help balance ecological processes and development at the same time.

Agro Issues

Agricultural Credit

By: Staff Reporter

Agriculture credit is a loan or extension of credit provided by a bank for agricultural or allied rural use – one of the most crucial inputs for agricultural development.

The Lost Seed

By: Staff Reporter

With the onslaught of green revolution and now the advent of genetically modified species, traditional seed culture practices are slowly but surely dying-out. India’s vast biodiversity in terms of indigenous agricultural landraces require to be revived to ensure conservation and ultimately food security.

Playing God-GM Foods

By: Staff Reporter

Genetic Modification is a process by which DNA of an organism can be altered to synthesise a new, usually better or more efficient version of the original organism. The breakthrough in science was initiated particularly in the field of agriculture, to improve crop protection through the use of one of the three basic traits: resistance to insect damage; resistance to viral infections; and tolerance towards herbicides. But, like all new technologies, GM crops also pose certain apprehensions and risks, both known and unknown.

Organic Agriculture-An Indian Perspective

By: Kirti Jain

Organic farming in India is a traditional practice. With the advent of chemical fertilisers, farmers chartered new paths to higher levels of productivity. With the ills of inorganic inputs now apparent, consumers in the global markets have turned towards organic food - yet again asserting its relevance.

Agricultural Calculations Decoded

By: Staff Reporter

The Indian agricultural scenario is experiencing a series of changes since the green revolution. Here is a brief essay that outlines concepts of how agricultural calculations are undertaken - agricultural productivity and efficiency, crop combination, degree of commercialisation, diffusion of innovation and more, to help comprehend the agricultural scenario with lucidity.

Fertilisers-Assisting Productivity

By: Staff Reporter

The increased use of chemical fertilisers in India came with the advent of Green Revolution in the 1960s. Introduction of fertilisers helped greatly to increase the food production in the country in a time when the agricultural sector was failing - as a repercussion to natural disasters. However, the continuum of the large scale usage is raising concerns about judiciousness and efficacy of chemical fertilisers in the present context.

India's Outdoors

Rinchenpong Beauty and its People

By: Sumit Chakraborty

A sleepy town in West Sikkim that is an epitome of rich heritage, natural beauty and culture - heaven on earth. Situated at an altitude of 5580 ft Rinchenpong is a fairly new but must go tourist destination.

Down the Ages-Excavation Sites in Chhattisgarh

By: Staff Reporter

The State is taking a keen initiative to explore and excavate sites that hold historical importance and at the same time Chhattisgarh is practising conservation and preservation of several sites with valuable historical credentials.

Editor's Note

Dear readers, Almost every movie made in this country, has compelling discourses on ‘mitti ki saugandh’ or the pledge of mother earth - to protect, defend and worship our soil for an eternity. Nothing could perhaps be further away from the truth however - in the real world, we defy all lofty id

Term Power

What is ...

Agroforestry is any sustainable land-use system that maintains or increases total yields by combining food crops (annuals) with tree crops (perennials) and/or livestock on the same unit of land, either alternately or at the same time, using management practices that suit the social and cultural characteristics of the local people and the economic and eco¬logical conditions of the area.

The term 'agronomy' is derived from the Greek words 'agro' meaning field and 'nomo' meaning to manage. Agronomy is a branch of agro science that deals with principles and practices of soil, water and crop and field management providing favourable environment for higher productivity.

A type of plant disease of warm humid areas that infects a variety of plants from trees to grasses. It is caused by certain fungus producing spores - tiny, sunken saucer shaped spots which often enlarge, leading to wilting, withering, and dying of tissues.

The term anthropogenic indicates the effect resulting from human activity. Anthropogenic effects, processes or materials are those that are derived from human activities, as opposed to those occurring in natural environments without human influence.

It is a type of cultivation, management and a science of the study of individual trees, shrubs, vines, and other perennial woody plants. The science includes cultural techniques such as selection, planting, fertilisation, pest and pathogen control, pruning, shaping, and removal. (e.g Bonsai)

Ethanol or ethyl alcohol (C2H5OH) is a clear colourless biodegradable liquid, low in toxicity - causing little environmental pollution. It is a high octane fuel and has replaced lead as an octane enhancer in petrol. Bioethanol is a form of renewable energy that is mostly produced from the sugar fermentation process.

A cultivar is a plant or group of plants selected for desirable characteristics that can be maintained by propagation, mainly for farming. Cultivars have generally arisen through years of cultivation but a few may be special selections from the wild.

A germplasm is a collection of genetic resources for an organism in the form of a living tissue. For plants, it can be a seed or another plant part – a leaf, stem, pollen or even just a few cells.

Grafting or graftage is a horticultural technique commonly used in asexual propagation whereby tissues from one plant are inserted into those of another in order to make a joint known as inosculation.

A propagule is any plant material that is used for the purpose of propagating. In asexual reproduction, a propagule may be a wood, semi-hardwood, or softwood cutting, leaf section, or any number of other plant parts whereas in sexual reproduction, a propagule is generally a seed or spore.
