Natural Farming

Crisis of Indian agriculture is very pertinent at this moment as green revolution is gradually losing its hope. Excessive, pointless exploitation of broods of green revolution has left bad footprints on country’s food security and environmental safety. With the motto to ensure food security by reviving Indian agriculture in environmentally safe way as well as to release farmers from debt cycle and suicides, zero budget natural farming (ZBNF) has come in the picture, which discards uses of all the chemical farming inputs and relies on natural way of farming i.e. rejuvenating soil and crop health through its own practices (Jivamrita, Bijamrita, mulching, soil aeration, intercropping, crop diversification, bunds, bio-pesticides etc.). ZBNF movement right now is the most popular agrarian movement which begun in 2002 in Karnataka and later successfully spread in many states (specially, of South India) of the nation through numbers of trainings, demonstrations and various promotional activities. Successful outcomes from farmers’ fields of south Indian states like Andhra Pradesh, Karnataka etc. are encouraging and grabbing attention of farmers, public and private organisations towards ZBNF in recent times. Yet, various controversies regarding its transparency,      inadequate information, efficacy, practices, idealisms, even the term ‘zero budget’ etc. have agglutinated around ZBNF over the years since it debuted. Critics in fact have cited several references of drastic yield reductions with ZBNF practices in many places. Adequate scientific evaluation or monitoring of ZBNF’s successes or failures through multi-locational trials is now therefore the needful before allowing or restraining its run in Indian agriculture.

The Past

After ensuring the food security for over 50 years, the green revolution is eventually reaching its biological limits which are very much reflected by the ongoing stagnancy in yield increased over the past few decades. Meeting the increasing food demands due to increasing population is the greatest challenge for today’s plant scientists. Changing climatic conditions are posing additional threats to crop growth, productivity and yield. After successfully deploying gene editing to modify simple traits, scientists are now embarked on more ambitious adventures in genomics to combat challenges of food security in the wake of increasing population and climate change adversaries. The chapter outlines use of new technologies in tailoring crops beyond simple traits aiming to harvest the desired diversity lost during domestication and manipulating complex traits, which evolved over evolutionary timescale with special emphasis on the development of climate smart crops.

This paper investigates the trends in area, production and yield of major pulses in India by using component growth rate, Instability index and decomposition analysis during last twenty years. Further the study period has been divided into three periods based on the implantation of NFSM: Pre NFSM period I (1995 to 2006), Post NFSM period II (2007 to 2016) and Overall period (1995 to 2017). The result of CGR in total pulses revealed that the area (1.87%), production (3.58%) and yield (1.89%) registered highly positive significance with increased growth in period II. The yield growth rate was higher than area growth rate implying that the area allocation under pulses is increasing poorly even after NFSM scheme, while improvement in yield is there. The instability of total pulses production and productivity has first decreased and then increased in the overall period its shows increased growth. Among the major crops, the area effect was high in lentil production and by yield effect was high in gram production and the interaction effect was high in moong production during the overall study period. In case of total pulses, area and yield effects were positively higher and they were responsible for total pulses production.

The stability of food supply chains is crucial to the food security of people around the world. Since the beginning of 2020, this stability has been undergoing one of the most vigorous pressure tests ever due to the COVID-19 outbreak. From a mere health issue, the pandemic has turned into an economic threat to food security globally in the forms of lockdowns, economic decline, food trade restrictions, and rising food inflation. It is safe to assume that the novel health crisis has badly struck the least developed and developing economies, where people are particularly vulnerable to hunger and malnutrition. However, due to the recency of the COVID-19 problem, the impacts of macroeconomic fluctuations on food insecurity have remained scantily explored. In this study, the authors attempted to bridge this gap by revealing interactions between the food security status of people and the dynamics of COVID-19 cases, food trade, food inflation, and currency volatilities. The study was performed in the cases of 45 developing economies distributed to three groups by the level of income. The consecutive application of the autoregressive distributed lag method, Yamamoto’s causality test, and variance decomposition analysis allowed the authors to find the food insecurity effects of COVID-19 to be more perceptible in upper-middle-income economies than in the least developed countries. In the latter, food security risks attributed to the emergence of the health crisis were mainly related to economic access to adequate food supply (food inflation), whereas in higher-income developing economies, availability-sided food security risks (food trade restrictions and currency depreciation) were more prevalent. The approach presented in this paper contributes to the establishment of a methodology framework that may equip decision-makers with up-to-date estimations of health crisis effects on economic parameters of food availability and access to staples in food-insecure communities.

Food security means, “All the people, all the time, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preference for an active and healthy life” [FAO (1996)]. Three types of food insecurity generally exist in any country, which are: transitory food insecurity that is short time food insecurity occurs due to sporadic crises; chronic food insecurity that arises as a result of long term but not easily changed conditions; cyclic food insecurity that arises due to seasonal fluctuations. If cyclic food insecurity existed in any country for at least six months than it was called as chronic cyclic food insecurity and if it persisted less than six months than called as transitory cyclic food insecurity. Pakistan has made a lot of progress since independence in the field of agriculture in terms of production, yields, and growth in area under cultivation. Indus agriculture has experienced a Green Revolution and is striving for yellow and blue revolutions. However, it could have done far better. Though the overall growth of the Pakistan’s economy has largely been dependent upon the performance of agriculture, over the years, not much investment has been made for the development of this sector. Agriculture performance still depends upon, quite a lot, upon the weather conditions every year. The yields of most of crops are far below the levels achieved at the progressive farms (extension gap). From the Figure 1 it is evident that in the last decade (90s) food availability was increasing and then went down and formed the inverted u-shape. After that again fluctuating means there is no surety about food security. It is also comparable with agriculture growth rate. According to latest statistics in Pakistan as many as 50 million people are engaged in agriculture operations and produce only 25 million tons of food grains. As against this in India, 546 million people are engaged in agricultural operations and produce 176 million tons of food grains, in USA only 6 million people engaged in agriculture, produce 347 million of food grains.

Appropriate plant biotechnology applications could be a major tool in the fight against hunger and poverty, especially in developing economies. Some promising results have already been reported through a range of biotechnology applications, for example the mass propagation of plants through in vitro clonal propagation, use of molecular markers and marker assisted breeding to improve plant breeding, use of bio-products and the application of molecular techniques for quick and accurate diagnosis of plant diseases. Thus, biotechnology may have the potential to deliver solutions to some of the shortcomings of the green revolution such as the limitations of conventional breeding, poor quality and insufficient quantity of planting materials available to farmers and the negative environmental consequences of high usage of inorganic pesticides and fertilizers. This chapter will elaborate the successful application of these technologies for sustainable agriculture and food security in developing economies. It is envisaged that through partnership between developing and developed economies, and assistance from international organizations and governments, capacity can be developed for developing economies to achieve the full potential of biotechnology and sustainability.

Despite the successes of the Green Revolution, about a billion people are still undernourished and food security in the developing world faces new challenges in terms of population growth, reduced water resources, climate change and decreased public sector investment. It is also becoming widely recognized that poverty is a cause of environmental degradation, conflict and civil unrest. Internationally coordinated agricultural research can play a significant role in improving food security by deploying promising new technologies as well as adapting those with well-established impact.In addition to the genetic challenges of crop improvement, agriculturalists must also embrace the problems associated with a highly heterogeneous and unpredictable environment. Not only are new genetic tools becoming more accessible, but a new generation of quantitative tools are available to enable better definition of agro-ecosystems, of cultivar by environment interactions, and of socio-economic issues, while satellite imagery can help predict crop yields on large scales. Identifying areas of low genetic diversity – for example as found in large tracts of South Asia – is an important aspect of reducing vulnerability to disease epidemics. Global strategies for incorporating durable disease resistance genes into a wider genetic background, as well as participatory approaches that deliver a fuller range of options to farmers, are being implemented to increase cultivar diversity.The unpredictable effects of environment on productivity can be buffered somewhat by crop management practices that maintain healthy soils, while reversing the consequences of rapid agricultural intensification on soil degradation. Conservation agriculture is an alternative strategy that is especially pertinent for resource-poor farmers.The potential synergy between genetic improvement and innovative crop management practices has been referred to as the Doubly Green Revolution. The unique benefits and efficiency of the international collaborative platform are indisputable when considering the duplications that otherwise would have been required to achieve the same impacts through unilateral or even bilateral programmes. Furthermore, while the West takes for granted public support for crucial economic and social issues, this is not the case in a number of less-developed countries where the activities of International Agricultural Research Centres (IARCs) and other development assistance organizations can provide continuity in agricultural research and infrastructure.
