Food security can be defined as ensuring that all people, at all times, have access to sufficient, safe and nutritious food that meets their dietary needs and preferences for an active and healthy life. Most countries aim to achieve food security by maximising production and thus reducing the reliance on imported food. Botswana is a net food importing developing country (NFIDC). The average annual food import bill over the last three years has been six billion Pula. The value of imported food as a proportion of all merchandise imports fell from 14.2% in 2000 to 8.7% in 2015. This resulted in Botswana’s ranking in the world moving from position 63 in 2000 to 100 in 2015. In this study, data provided by Statistics Botswana were disaggregated to separate foodstuff from beverages and tobacco. Over the last three years, one fifth of imported food valued at just over one billion Pula per year, has been staple cereals (sorghum, maize and wheat). Seventy five per cent of all imports are from South Africa which makes the country’s position of food insecurity even more precarious. An argument is presented to encourage the irrigation of staple cereal crops so as to increase production and thus substitute for imports, create employment and improve the food security status of the country. In particular, it is argued that deficit irrigation should be adopted as a matter of policy, allowing the most efficient use of limited water resources and resultant increase in irrigated area and quantities of staple foods produced.

Climate prediction models suggest that agricultural productivity will be significantly affected in the future. The expected rise in average global temperature due to the higher release of greenhouse gases (GHGs) into the atmosphere and increased depletion of water resources with enhanced climate variability will be a serious threat to world food security. Moreover, there is an increase in the frequency and severity of long-lasting drought events over 1/3rd of the global landmass and five times increase in water demand deficits during the 21st century. The top three cereals, wheat (Triticum aestivum), maize (Zea mays), and rice (Oryza sativa), are the major and staple food crops of most people across the world. To meet the food demand of the ever-increasing population, which is expected to increase by over 9 billion by 2050, there is a dire need to increase cereal production by approximately 70%. However, we have observed a dramatic decrease in area of fertile and arable land to grow these crops. This trend is likely to increase in the future. Therefore, this review article provides an extensive review on recent and future projected area and production, the growth requirements and greenhouse gas emissions and global warming potential of the top three cereal crops, the effects of climate change on their yields, and the morphological, physiological, biochemical, and hormonal responses of plants to drought. We also discuss the potential strategies to tackle the effects of climate change and increase yields. These strategies include integrated conventional and modern molecular techniques and genomic approach, the implementation of agronomic best management (ABM) practices, and growing climate resilient cereal crops, such as millets. Millets are less resource-intensive crops and release a lower amount of greenhouse gases compared to other cereals. Therefore, millets can be the potential next-generation crops for research to explore the climate-resilient traits and use the information for the improvement of major cereals.

Cereal crops such as maize, wheat, sorghum and pearl millet are important for human consumption due to their nutritional benefits. These cereals play pivotal roles to meet world’s food demand. However, maintenance of food security particularly in the circumstance of changing climate, constantly urges for modification of agro-techniques and one such modification is the incorporation of transplanting technique in these cereals as an alternative under a non-practicable situation of direct sowing. Transplanting is a method of transferring seedlings grown in nursery or others to the field. It has been already found to shorten the crop duration and improve germination, plant stand, seed and seedling quality parameters, growth, yield and economic profitability of these cereals. Besides, research findings are also available stating that transplanting helps these cereals to cope up with vagaries of weather and to exhibit greater radiation and water use efficiencies and suppression of weeds. Outcomes of transplanting are however dependent on various factors like methods of nursery raising, the variety used, mode of planting, age of seedlings etc. In spite of these prospects, transplanting technique is not so popular in these cereals due to poor dissemination, discouraging research findings, pest and disease problems, lack of suitable package of practices etc. Therefore, focuses are to be given in conducting more and more research trials to confirm its location and situation wise efficacy and also in developing and disseminating a suitable package of practices of transplanting accordingly.

We retrace the construction of AgriGIS framework between multiple disciplines around a common objective of facilitating research on model simulations for sustainable food security. The geospatial media enabling multidisciplinary research in crop modelling but also supporting new types of hypothesis and analysis, is described with interoperability principles and seamless access and sharing for data, metadata and processing models. Designing the platform achieving this main objective generated a transdisciplinary vision of modelling and forecasting for sustainable agriculture.
