role of soil science in sustainable agriculture

This could mean that the wealth of Sub-Saharan African nations depends on their ability to sustainably conserve and manage soil resources. Soils having micro-pores hold water very tightly whereas those soils having larger pores (macro) hold their water loosely (Johnson, 1991). A common philosophy among sustainable agriculture practitioners is that a "healthy" soil is a key component of sustainability; that is, a healthy soil will produce healthy crop plants that have optimum vigor and are less susceptible to pests. The understanding of basic soil science is important for many different reasons on the farm. Abstract. The goal of achieving a sustainable planet, one that will accommodate the basic needs of its present inhabitants while preserving the resources that will enable future generations to flourish, has gained increasing acceptance. US Secretary for agriculture has blasted the EU’s “Farm to Fork” strategy and the continent’s reluctance to use new technologies in agriculture, in heated debate over how to make food production more sustainable. Since 1994, when the first edition of this Special Reference Brief was compiled, \"sustainability\" has become a more familiar term. The use of these organic amendments can improve the growth of plants in a range of ways; number of leaves, seed germination, root biomass, fruit abundance, number of seeds, and overall yield. Sustainable agricultural practices are intended to protect the environment, expand the Earth’s natural resource base, and maintain and improve soil fertility. towards soils with higher soil organic matter will actually lead to healthier soils (Castro and Hartz, 2016), there is an ongoing debate over the role of soil health management in science-based agriculture. Globally, the contributions of soil scientists regarding this idea have been forwarded and edited by Hartemink (2006b). Agriculture that covered all components of agronomic productions depends fully on soil and its quality (Brady and Weil, 2007). Scow is also Chair of the International Agricultural Development Graduate Group. For it’s only through recognising the importance of science, invention and technology that we can possibly hope to guarantee a truly sustainable future, for Australia, and for … All cash and economic crops such as cotton, sugarcane, tobacco, edible and non-edible oils, rice, wheat, maize etc., are grown on soil. Generally, there is significant population increase and demand for food, water and shelter in the entire Sub-Saharan African nations (DESA., 2013). Soils science is essential to understanding the conditions that affect and support life on Earth: Thus, soil could be refers to as production, promotion and distribution of essential services needed for the sustainable crop production in Sub-Saharan Africa. Engineering and landscaping industry: Soil serve as the base environment for homes, roads, educational institutes, health centers, government and non-governmental buildings. Importance of soil to agriculture. These are substantial part of soil processes: Physical, chemical, biological and ecological that control the overall systems in soil formation and soil conditions (Jenny, 2009). Soil Science. Importance of the Soil In Agriculture. The concepts of inheritance and Mendelian genetics were soon to follow in 1865 and subsequently stimulated the biological basis for modern agriculture. Several of the grand challenges facing science today involve being able to better manage our Earth’s soil resources: Feeding 9 Billion people sustainably via intensification of agriculture, preserving our water resources in the face of a changing climate, effectively restoring and rehabilitating damaged ecosystems for future use, and becoming more efficient at the stewardship of nutrients required for all living things. Soil fertility. The climate has been characterized as semi-arid with an average rainfall equaling 600 mm (more or less) and variations of up to 30 or 40% (FAO., 1995). https://scialert.net/abstract/?doi=ijss.2016.61.70, Relationship between soil, sustainable crop production and economic development, Reconnecting the knowledge chain, linking tacit with scientific knowledge both ways, Learning to deal with wicked environmental problems for which no single solutions exist but only a series of alternative options for action, balancing economic, social and environmental considerations, Educating knowledge brokers, linking science with society in land-related issues, acting within a Community of scientific practice. He is considered one of the founding and premier scientists in the world in sustainable and organic agricultural research, as evidenced by his more than 200 scientific publications, some of which have been published in Science, Nature, Proceedings of the National Academy of Sciences (PNAS), Scientific American, and other land-use and soil science journals. The wildlife living in different areas of Sub-Saharan Africa stayed well-protected around the vast land of the region. In saturated soil condition, these pores become accommodated with water, when drained-out of larger pores the soil will become unsaturated, and finally ends in the ground as ground water (Johnson, 1991). Google Scholar. Therefore, if soil and soil resources are given the considerations they deserved, much can be achieved in Sub-Saharan Africa. The concept of "scientific agriculture" dates to publications by Liebig in 1840 and Johnston in 1842, which speculated about the role of chemistry in agriculture (Pesek, 1993). Soil science: Role, challenges and gaps in future: There have been several developments in the past decades regarding the role and challenges of soil science in future (Hartemink, 2006b). Soil science provides support to crop production, raw materials to million industries, water quality for biota, animal and human survival, recycling of abundant dead materials, landscaping for engineering and research purposes, foreign exchange for national income … Agronomy for Sustainable Development, Springer Verlag/EDP Sciences/INRA, 2008, 28 (1), pp.33-46. Millions of people in rural areas of Sub-Saharan Africa live below the poverty line and more than half of them are extremely needy (Ehui and Pender, 2005). Sustainable Agriculture. We thank the European Geosciences Union for supporting the session on Soil Management for Sustainable Agro-Food Systems at the General Assembly in April 2011, all the reviewers for their timely reports and constructive comments, and the staff of Editorial Office of Applied and Environmental Soil Science for their assistance throughout this project. (2011), meeting this demand would means requiring about 175-220 million ha of additional cropland, globally. This is because, the global challenges to sustainable development have been driven by a broad set of mega-trends, which include; changing demographic profiles, changing economic and social dynamics, advancements in technology and trends towards environmental deterioration (DESA., 2013). Figure 2 provides an improve understanding of the common relationship between soil science, crop production, sustainability and economic development. 1. Cultivation and tillage play an important role in agriculture. Based on a multi-pronged goal, sustainable agriculture seeks to:Increase profitable farm incomePromote environmental The soil scientists understood that soil is part of earth crust where mineral particles are formed as a result of physical, chemical and biological processes. Crop production depends fully on quality of soil and its fertility (Lal, 1998). Leveraging the world’s largest repository of agroforestry science and information, we develop knowledge practices, from farmers’ fields to the global sphere, to ensure food security and environmental sustainability...read more, Transforming lives and landscapes with trees, © 2020 World Agroforestry All rights reserved. . It is quite true that this need will never be achieved if our soils are not been preserve and maintain, properly (UNCCD., 2012). Their protection is of the utmost importance to ensure the future of agri-food systems and the provision of key ecosystem services. According to Dobbs et al. The most affected countries of the region include; Benin, Cameroon, Chad, Côte d'Ivoire, Ethiopia, Ghana, Guinea, Guinea-Bissau, Mali, Mauritania, Niger, Nigeria, Senegal, Somalia, Sudan and Togo. Agriculture often places significant pressure on natural resources and the environment. The analysis provides evidence supporting the hypothesis that agricultural intensification negatively impacts on soil biodiversity and ecosystem functions. A. Ayantunde, A. J. Duncan, M. T. van Wijk, P. Thorne This will continue to be a long term debates because of the relationship that always exist between sustainable development and other components of human life-economic, social, political and environment (DESA., 2013). The paper focuses on conservation agriculture (CA), defined as minimal soil disturbance (no-till, NT) and permanent soil cover (mulch) combined with rotations, as a more sustainable cultivation system for the future. Microorganisms can provide active and passive advantageous impacts on crops by nutrient enhancement and by reducing damages caused by plant pathogens or environmental conditions ( Prasad et al., 2019 ). Consequently, soil science can be considered a key to sustainable crop production for economic development in Sub-Saharan Africa. The Sub-Saharan Africa needs urgent sustainable crop production for economic development. While, soil degradation caused by combined social and climate factors has reached the level of acceptance. For decades, soil has been associated with the production of vital crops, herbs, raw materials and variety of human needs for sustainable development (Brady and Weil, 2007). Nevertheless, it is the aims of the World Economic (WE) and Social Survey (SS), 2013 to make sure that any contribution towards the considerations on sustainable development focus on three important issues, which are: sustainable cities, food security and energy transformation (DESA., 2013). This study outlines the role of soil science as an answer to sustainability and renewability of crop production for economic development in Sub-Saharan Africa. Soil science is the mainstay of the economic development for the Sub-Saharan African region. Permaculture. Permaculture is a design system that applies principles that are found in nature to … The export services have created many ways of revenue generation to Sub-Saharan African nations. While agriculture has historically been a significant contributor to greenhouse gas emissions, Dr. Lal demonstrated the critical role of soil in ensuring a climate-resilient future. E-mail: tnogeire@gmail.com. Recycling of dead materials: Soil serve as natural mechanism that recycle and transform abundant of materials in the global ecosystem. Soil biodiversity constitutes an important part of the terrestrial food web and plays a major role in sustainable agriculture. The soils under natural vegetation normally support the population of organisms and soil animals in an active biological activity. Hence, millions of jobs could be lost without this function of soil-in government or non-governmental sectors. Therefore, application of soil science resources information into vast environmental resources available would help to increase crop production, forest management, water quality, animal production and poverty reduction. (2012). Soil plays an important role in farm ecosystem by providing nutrients essential for the growth of agricultural and horticultural crops. Agricultural education programmes give the added advantage of the opportunity to see or know how it is done, that is, the practical aspect of soil analysis, maintenance and improvement of its fertility, the production, preservation and processing aspects of animal and crop sciences… We all know that soil is a key element of agriculture. Soil science, sustainable crop production and economic development: The multifunctional services of soil science as an answer to sustainability and renewability of crop production for the economic development of Sub-Saharan Africa is considered to be determined, by the combined influences of soil properties, soil quality and soil management (Brady and Weil, 2007). It also improves the nutritional quality of crops by increasing sugar, oil and protein compounds. Fertile soil is rich in nutrients and water highly suitable for agriculture and serves as the primary nutrient base for healthy crops. A review Christos Dordas To cite this version: Christos Dordas. This study outlined and discussed these functional services of soil science as an answer to sustainability and renewability of crop production for economic development in Sub-Saharan Africa. However, the wider benefits of soil biodiversity have been largely ignored by traditional and conventional agriculture in Africa. Role of nutrients in controlling plant diseases in sustainable agriculture. The biota (micro and macro-organisms) depends fully on soil for their basic needs and survival: air, water, food and shelter (Coleman, 2001; Barrios, 2007). Farmers and ranchers produce the food and fiber we use every day. these crops are exported from Sub-Saharan Africa to many regions in the world for economic development. (1992). They are particularly useful in converting vast renewable resources from rangeland, pasture, and crop residues or other by-products into food edible for humans. Soil accommodates diverse living organisms: Bacteria, fungi, actinomycetes, yeast and algae; earthworms, termites and arthropods; protozoa and nematodes (Ritz et al., 2010). As a result, these plants produce important needs … This makes biofertilizers a powerful tool for sustainable agriculture and a sustainable environment. This recycling process, also improves environmental quality, water quality and human health conditions by minimizing the risk of mosquito populations as well as beautifying environment and its biological surroundings. This work synthesizes the current state of knowledge and highlights the unique challenges to management of soil biodiversity in African agriculture. Ruminants have served and will continue to serve a valuable role in sustainable agricultural systems. Understanding about topsoil formation and conservation is then related to sustainable agriculture and carbon sequestration and its importance in mitigating climate change. Microorganism plays very important role in agriculture because the soil microbes (bacteria and fungi) are essential for decomposing organic matter and recycling old plant material. (2014) noted that the future of soil science depends on the continent’s distinct characteristics: Its high concentrations of poor farmers using poor agronomic tools to work soils dominated by low inherent fertility in support of national economies. The results focus on farmers becoming sustainable soil managers and the role of science in this transition. These organisms interact with one another and with variety of living and non-living materials to improve soil quality, soil fertility and soil health for economic development of crop productions (Coleman, 2008; Castro-Huerta et al., 2015). Soil is investigated in relation to and as integral part of terrestrial ecosystems but is also recognized as a manageable natural resource. Our paper lays emphasis on the role of soil science towards achieving sustainability and renewability of crop production for economic development. Sustainable agriculture means the production of food from plants or animals using different agricultural techniques that protect communities, the environment, and animal welfare. Generally, there are many contradictions regarding the links between sustainability, soil environment and economic development (DFID., 2000). There is also some uncertainty regarding the extent to which To meet the demand, agriculture practices are using intensive amounts of chemical-based fertilizers and pesticides, which ultimately leads to land degradation and biodiversity loss. This ground water is useful for various human economic benefits. The meaning of sustainable economic development entails (Greenland and Szabolcs, 1993): Management and conservation of the natural resources base and the orientation of technological and institutional changes in such a manner, as to ensure the attainment and continued satisfaction of human needs for the present and future generation. International Symposium on Food Safety and Quality: Applications of Nuclear and Related Techniques, Vienna, Austria, 10-13 November 2014 Tanzania Atomic Energy Commission Abdalah Kileo,Simon L C Mdoe,Alan E Waltar & Iddi S N Mkilaha. It would be naïve to think that scientific products will hold the only solutions.A recent book took that very line, arguing that there is no need to be concerned about the future because humans will always have technology and innovation to get out of trouble [21] . The value of soil must be recognized and considered in all aspects of global economic developments. Starting in the 1960 to date, some major developments in soil science were noted (Mermut and Eswaran, 2001), although ideas and challenges on the future of its science are expanding more dynamically than ever. 3. As a result, poor soil quality, declined soil fertility and environmental quality have capitulated decreased in food production and economic profits in the entire African region (FAO., 1995). In this blog post I would like to focus a little bit more on the technical side of soil and explain some of its chemical and physical properties. The meats, feathers, animal skins and variety of wildlife materials are used by human population for diverse economic developments. Communications in Soil Science and Plant Analysis: Vol. And, also could be part of most effective means for integrating economic, social, political and environmental objectives in reducing poverty and hunger (DFID., 2000). In Rwanda, Rushemuka et al. The abundant of dead materials-plants and animals, unwanted food and non-foods materials are recycled by soil through decomposition processes-physically, chemically and biologically (FAO., 2005). Soil science as an independent sub-discipline of science and technology of crop production has played and continuous to plays a vital roles in Sub-Saharan African economic developments (Muchena and Kiome, 1995). Therefore, soil science as a disciplinary of science could be regarded as one of the key components that play role towards achieving sustainability in Sub-Saharan Africa. The sustainability of crop production is of great challenges to soil and crop scientists and of course a task to governments of Sub-Saharan Africa. 23, Soil Testing and Plant Analysis in … Economic environment for crop production: Soil served as a potential environment for growth and development of all kinds of crops and plants. There are many resources information generated by soil science in Sub-Saharan Africa (Muir et al., 1957; Moss, 1965; Jones and Wild, 1975; Chartres, 1982; Kundiri et al., 1997; Warren et al., 2001; Ehui and Pender, 2005; Bationo et al., 2006; Usman, 2011; Petersen, 2008; Furian et al., 2011). The interactions between soil environment and variety of wild-animals as well as reared cattle have resulted in many economic benefits between one country to another and between Sub-Saharan Africa to other continents. These served as an important source of revenue, job creation and industrial developments to many countries in Sub-Saharan Africa. The role of science in sustainable agriculture Boru Douthwaite, Impact and Adoption Specialist, International Institute of Tropical Agriculture (), Ibadan, NigeriaThe 2000-2001 World Resources Report found that environmental damage, much of it to agricultural land, could have devastating implications for human development and the welfare of all species. Available record shows that by 2025, Africa would be able to feed only 40% of its growing population (FAO., 1995). This has emphasize that if we do not join hands to protect, manage, conserve and restore soils properly, the multifunctional roles of soil science to crop productions would not provide a satisfactions of human needs in Sub-Saharan Africa. It is therefore stressed that the time has come for the Sub-Saharan African countries to integrate ideas to improve and manage soils for permanent economic development, sustainably. These allowed soil scientists to expand the recovery of many important soil research projects that are sustainable in ensuring the goals of soil science for the next 75 years to come (Simonson, 1991). Review: Role of herbivores in sustainable agriculture in Sub-Saharan Africa - Volume 12 Supplement - A. Sustainable agriculture is farming in sustainable ways, which means meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. Hence, the role of soil and its applied science is of utmost important for sustainable crop production and economic development in Sub-Saharan Africa. Millions of people are directly or indirectly depend on this function of soil. The quality of their life is poor and needs urgent sustainable development particularly in the aspect of crop production. This paper discusses the role of soil science in East Africa dating back to the beginning of this century up to the present day. The variety of fruits, forest timbers and vegetables are used by many industries in the productions of wood materials, juices, medicines etc. 43, No. The Role of Urban Agriculture in a Secure, Healthy, and Sustainable Food System Theresa Nogeire-McRae, Theresa Nogeire-McRae Department of Soil and Crop Sciences, Colorado State University . hal-00886444 Agron. A bicultural of legume and non-legume can be used with the objective to provide both benefits together [26] . However, the most important roles of soil science as an answer to the subject matter are discussed in the last session. Reactor and transformer of natural resources: Soil integrates the influence of solar radiation, atmosphere, ground and underground water, biological and ecological resources (Varallyay, 2010). Hence, the multifunctional sustainable soil management for economic crop production must meet the requirement of soil to be classified and described as ‘soil quality’. Soils Support Agriculture MARCH 2015 Importance of Soil to Agriculture Agriculture is one of the most important components of our society. Role of Soil Organic Matter in Maintaining Sustainability of Cropping Systems. Italian Society of Soil Science School of Soil Biodiversity and Bioindication XII cycle SOIL MANAGEMENT AND QUALITY IN THE ERA OF SUSTAINABLE AGRICULTURE INTENSIFICATION Faculty of Food, Agriculture and Environmental Sciences Università Cattolica del Sacro Cuore, Piacenza, Italy 16 – 18 JUNE 2020 FIRST ANNOUNCEMENT SCHOOL TOPIC AND AIMS In spite of the emergency created by … They also serve as machinery that helps to decompose and transform various organic materials in the production of bio-organic fertilizers (Li et al., 2014). … Soil biodiversity constitutes an important part of the terrestrial food web and plays a major role in sustainable agriculture. In recent years the importance of sustainable agriculture has risen to become one of the most important issues in agriculture. And, it is believed that if this can be achieved scientifically, traditionally, politically and socially, there is a strong backing that soil science will emerge number one contributor in agricultural transformation systems for sustainable economic development in Sub-Saharan Africa. Thus, soil provides a source of energy and functional support for economic development in crop production systems. The fully decomposed materials add organic matter to the soil and enhance soil quality and soil fertility for high and economic crop yield production (Li et al., 2014). All our food needs good soil to grow in. Kate Scow is Professor of Soil Science and Microbial Ecology in the Department of Land, Air and Water Resources and Director of the Russell Ranch Sustainable Agriculture Facility that hosts the Century Experiment. Maintaining good soil quality is crucial for the sustainability of agriculture. In the following sections, I illustrate three stages of participation in the SSM farming CoP based on the interview material: seeking, experimenting and contributing. Sustainable agriculture is farming in sustainable ways, which means meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. The book covers the latest research on biofertilizers, ranging from beneficial fungal, bacterial and algal inoculants; to microbes for bioremediation, wastewater treatment; and recycling of biodegradable municipal, agricultural and industrial waste; as well as biocontrol agents and bio-pesticides. Role of nutrients in controlling plant diseases in sustainable agriculture. There are many views and contributions on the theme. It is the pedosphere environment, where, four entities (Brady and Weil, 2007): Atmosphere (world of air, gases), hydrosphere (world of water-oceans and seas), lithosphere (world of rocks and mountains) and biosphere (world of living organisms) interact and communicate for the benefits of global ecosystem, crop production and human developments. This water is useful for an ideal growth of plant roots, animals and microorganisms. However, in recent years there has been a remarkable increase in human population in most part of the Sub-Saharan African region. James Lind Institute is a pioneer in the field of online training courses in various fields such as clinical development, public health and tropical medicine, pharmaceutical medicine, medical communication and journalism and social and environmental sciences. Biofertilizers play a major role in sustainable agriculture. It can be based on an understanding of ecosystem services. The water quality, land quality, forest quality, animal and environmental qualities are factors, which must be maintained for better livelihoods of Sub-Saharan citizens (Lal, 1998). Karlen et al. In addition, plant diseases continue to play a major limiting role in agricultural production. In October 2014, the Committee on World Food Security (CFS) requested its High Level Panel of Experts for Food Security and Nutrition (HLPE) to prepare a report on sustainable agricultural development for food security and nutrition, including the role of livestock, to be … Soils are essential to life on Earth. This study aimed to evaluate the effectiveness of the visual soil assessment (VSA) method by testing it on two soil types and two agricultural management practices (AMP) (organic and integrated) that are considered to protect soil quality. Soils are a multifaceted and dynamic natural resource that support plant growth and affect water and air quality. However, the wider benefits of soil biodiversity have been largely ignored by traditional and conventional agriculture in Africa. Despite this contribution in the field of soil science, there is however, some contradiction opinions that achieving sustainable economic development in any form requires integration of ideas from different perspectives (DFID., 2000). Agricultural soil science studies the chemical, physical, biological, and mineralogical composition of soils as they relate to agriculture. The global population grew to seven billion in 2011, and by 2050 it is expected to reach over nine billion. The sustainable management of this relationship requires a join hands to help obtain adequate soil-crop information that could serve as a guide to the achievement of sustainability and renewability of crop production for economic development in Sub-Saharan African region. Those who understand these microbes, however, clearly see their involvement in crop rotation, integrat­ ed pest management, fertilizer management strategies, biological control, and soil conservation (Lynch, 1990). The global market for biofertilizers 2013) Biofertilizers may be defined as “subst to the host plant (Malusa Correspondence M Santhosh Kumar Department of Soil Science, lost in the form of immobilization, leaching, volatilization CCS Haryana Agricultural University, Hisar, Haryana, Foreign exchange development: Soil provides an economic means of foreign exchange between one country to another. Vital roles of soil science for an economic development: Soil and soil functional services are backbone of agricultural economic development in Sub-Saharan, Africa ( Kalpage, 1976; Okigbo, 1991; Hartemink, 2006a). Poverty and hunger, soil degradation and decline soil quality are increasingly alarming in the region. This function of soil has long been recognized in the development of various systems of agriculture, land quality, water quality and types of social, cultural and industrial civilizations. Therefore, the rational of soil science for the sustainable crop production would undoubtedly provide huge opportunities to Sub-Saharan African’s economic developments (Greenland, 1991; Bouma, 2001; Bekunda, 2006). Its economic impact has affected many regional developments as it touched the national and international financial budgeting (Warren et al., 2001; Bationo et al., 2006). They tell us whether the soil has the potential to store enough water to keep plants growing through a drought, to resist a flood, and to provide a right condition of chemical nutrients to plant so that the crops will grow healthy for economic development (Levine, 2001). Sustainable development, innovation and the role of science in food production were the themes of a seminar hosted by the U.S. Sustainability Alliance (USSA) in Warsaw on December 6.
