Agriculture and Climate Change in Southeast Asia and the Middle East: Breeding, Climate Change Adaptation, Agronomy, and Water Security
The agriculture of Southeast Asia and the Middle East is under threat due to vagaries of abiotic stress including climate change and water-related factors. With a particular focus on the challenges facing non-industrialized and developing countries, this paper attempts to create a framework for policy makers and planning commissions as well as increasing national and regional water stress awareness. The study elaborates the agriculture eminence, water provision, conventional water usage, and adverse consequences of water status under the changing climatic conditions and urban or industrial development. The study addresses the nature of problems, regional issues, current barriers, farmer’s perceptions, and concrete efforts to save regional agriculture for sustainable food security. The consequences of climate change, water stress, and salinity have affected huge areas of developing countries from an economic and resource security perspective that leads to disaster and unstable law and order issues. Long-term planning over timescales beyond the human lifespan and anticipation of threats and opportunities is required. Consequently, an emergency plan is also needed for international, national, and regional footprints including procedures for climate change mitigation and to implement inclusive plans to combat prevailing poverty, social changes, and allied anticipated risks. It elaborates the attempts to provide a framework for policy makers and political understanding to check the hidden but viable issues relating risks of climate change in local and global scenario. It is concluded that a viable charter of climate proofing and domestication is the way to success from on-farm-to-lab and lab-to-field outreach to mitigate declining food issues. The regional and international collaborative efforts are focused to modernizing crop genetics, agronomy, field-to-fork scrutiny, and adaptation training to increase quantity and quality of food with sustainable use of water.
KeywordsClimate change Irrigation scheduling Quality food Southeast Asia
The agriculture of Southeast Asia and the Middle East is mainly dependent on rain and groundwater which is, with current crops and management practices, neither sufficient nor reliable to meet the requirements of the crops (Noorka and Afzal 2009). Due to this, crop production is under serious threat, and potentially for survival, given the vagaries of abiotic and biotic stress under the changing climatic conditions. The consequences of climate change, water stress, and salinity have not only affected huge areas but also health and socioeconomic issues throughout the world particularly in the developing countries, leading to severe poverty, shaken resources, food insecurity, internal and external security issues, and catastrophes. Under the burgeoning population pressure including increasing urbanization, and severe weather conditions, Southeast Asia and Middle East countries will suffer food shortage in the coming decades if the present momentum of climate change situation persists for longer time as it is predicted. So short- and long-term planning over timescales, according to the wishes and necessities of human lifespan, is needed.
Climate Change and Agriculture
Climate is considered as the average weather and variations in relevant quantities for a number of decades, centuries, or potentially years. According to the World Meteorological Organization, the classical periods lag for a long time with the surface variables like wind, rainfall, and prevailing temperature. Change in climatic conditions result from natural climatic variations, solar cycles, volcanic eruptions and atmospheric changes and have direct consequences on land and water inhabitants flora and fauna (Pahl-Whost 2007; O’Brien et al. 2008). The climate change commitment is simply an account of predicted future changes in shape of hydrological cycle, changes in sea level, and rise and fall in weather conditions with constant anthropogenic emissions. It is anticipated that climate change takes place over a few decades or less, which directly or inversely has the potential to provide substantial interferences in humans as well as in ecosystems (Kashyap 2004; New et al. 2007). The immediate action to combat climate change is adaptation, a process of larger and smaller changes required to anticipate expected outcomes of climatic effects, by exploiting beneficial opportunities and minimizing harmful effects. In our natural systems, the process of sectioned resources management by augmentation of applied and basic research is suggested to tackle the forthcoming climatic threats (Power et al. 2005; One World Sustainable Investments 2008). Climate change and agriculture are interrelating and dependent on each other (IPCC 2007). Climate proofing and domestication of plants have played significant role to counteract changes in climate over the 10,000 years of human agriculture and have the potential to meet the challenges of global warming which have significant impacts on agriculture by the interaction of various elements like rainfall, fluctuating temperature and carbon dioxide concentration, glacial runoff, etc. to ensure crop maximization (Challinor et al. 2009; Fischer et al. 2002).
The optimum natural selection and adaption could lead to genetic erosion as well as nonconservation of genetic resources, so care must be taken to avoid such loss of valuable genetic resources. Thus, the affiliation in climate change and agriculture is in multiple ways confounded and contrasted: agriculture significantly contributes towards climate change, and climate change can detrimentally distress agriculture.
Adverse Consequences of Water Status Under Changing Climatic Conditions
Agriculture in Southeast Asia and the Middle East
The geographical situation in this area predicts that under the changing set of climatic situation up to 2050, most countries will become hotter, have less and un-reliable rainfall, and as a consequences sever reduction in agricultural production if the current policies, crops and genetic attributes are retained unchanged.
Agriculture is the social and economic core and main employer in many developing countries. Drought and its consequence of desertification with salinity and soil loss are expected to increase in the coming decades, with disastrous consequences from climate change (Moss and Dilling 2004; Hampel 2006). Droughts impose a serious threat to agricultural production and development of socioeconomic activities in the semiarid and arid regions by low rainfall, poor or low-nutrient soils, high temperatures, high solar radiation, and low precipitation. A viable charter of climate proofing and super-domestication through genetic improvement, in combination with optimized agronomy, is the way to success from on-farm to lab and lab to field outreach to mitigate declining crop productivity and food issues. The regional and international collaborative efforts are focused on research and experiments to modernize the crop genetics, agronomy, field-to-fork scrutiny, and adaptation training to increase quantity and quality of food with sustainable water harvest.
Current Barriers in Understanding
Introduction and problem identification of climate change is expected to make this seasonal distinction even stronger, with more frequent summer droughts coupled with increased winter rainfall and more floods. On-farm water storage of the higher winter flows is one of the main options for securing a more reliable water supply for irrigation. The media, the most effective weapon of present time, have to play a major role in converting the people’s perception to portraying climate change (Hampel 2006). Sometimes, media reports create confusion using their own perception without considering the expertise and scrutiny of the scientific community (Moss and Dilling 2004). Water availability and its predicted more frequent shortage are important barriers for efficient crop productivity that vary from one spatial scale to another. Reckoning crop water productivity, it is determined that there is gap among policy makers, consultant, researcher, extensionist, agronomist, and farmers themselves to enjoy the full supply of crop water productivity. However, a big breakthrough was observed with the employment of molecular breeding, domestication, and climate proofing (Heslop-Harrison and Schwarzacher 2012).
The farmers are the most beleaguered community of Southeast Asia and Middle East societies. The governmental policies to confront the negative image of climate change, food insecurity, middleman role in agricultural marketing, insufficient storage facilities, conventional agricultural production practices, lack of extension services, and technology transfer (Schulze 2000; Roux et al. 2006). The young people in the farming community are absconding towards the big cities in search of livelihood and ignoring their small landholdings. The old people, their forefathers, are unable to understand the latest technologies to employ in agriculture and to achieve the potential of the varieties. The media and agriculture department can play an important role to educate the farmers (Jury and Vaux 2005), while governmental healthy and farmer-friendly policies like timely announcement of support price of staple food as well as cash crops, farms to market road access, water provision, water stress tolerant varieties, and quality production.
Concrete Efforts to Save Regional Agriculture for Sustainable Food Security
Genetic resources are the vital source of crop production and food security across the borders (Von Bothmer et al. 1992; Skovmand et al. 1992). The range of genetic diversity within crops and their relatives is a precarious source for potential increase in crop production and for new sources of resistance and tolerance against biotic and abiotic stresses (Ahmad et al. 2010). The Food and Agriculture Organization of the United Nations (FAO), the Commission on Genetic Resources for Food and Agriculture, the International Plant Genetic Resources Institute (IPGRI), and the International Board of Plant Genetic Resources (IBPGR) have played an important role in the publication and preservation of germplasm (Skovmand et al. 1992). The International community has the obligation to aid agricultural research systems world-wide in the context of climate change to ensure world’s food security and peace. Building a partnership for development is one of the United Nations’ Millennium Development Goals.
The consequences of climate change, water stress, and salinity have affected huge areas of developing countries from an economic and resource security perspective, which leads to disaster and unstable law and order issues. Long-term planning – over timescales beyond the human lifespan – and anticipation of threats and opportunities are required. Consequently, an emergency plan is also needed for international, national, and regional footprints including procedures for climate change mitigation and to implement inclusive plans to combat prevailing poverty, social changes (including urbanization of populations and changes in diets), and allied anticipated risks. The researchers urge more climate proofing infrastructures, water scheduling, improved drainage, and water harvesting. The water resource management, use of treated wastewater, serious attempts to limit greenhouse gas emissions, societal impacts on climate change, and shortening/shifting the growing periods of crops will definitely help the researchers to cut down the negative impact of climate change. The study attempts to provide a framework for policy makers and political understanding to check the hidden but viable issues relating to risks of climate change in local and global scenarios.
