This is the second edition of Cropping Systems for Sustainable Wheat Production, attractively produced with 132 full colour images providing up-to-date information for producers or anyone interested in the industry. The importance of worker and environmental safety and hazard reduction is emphasised and a sample risk assessment template is included. There is a description of the precautions to take for the range of enterprise activities: from tractor work to handling and storing grain. The advantages of technology such as Global positioning by satellite (GPS) and Differential GPS (DGPS) and Real-Time Kinematic (RTK) for the broadacre enterprise are explained. GPS allows for “straight line” or tramline or controlled traffic farming (CTF) or the ability to geo-reference boundaries and points in a farm or paddock. DGPS is an even more accurate measurement of row spacing, as accurate as 10 cm and often used for CTF and RTK down to 2 cm and makes CTF easier to implement with inter-row sowing. GPS also has other advantages such as mapping the changes in yield throughout your paddock and so identifying areas where it is economic to apply more (or less) inputs such as ameliorants, seed, fertiliser or pesticides. The application of variable rate technology delivers fertiliser or herbicide in quantities as required by different sections of the paddock. This saves money and also protects the environment from unnecessarily heavy rates of product. This technology can also be used to gather paddock data using remote sensing technologies such as from satellites or UAVs (Drones). Sensitivity of imagery collected this way can help identify problems occurring before the human eye can see them and can direct the grower to issues before they become too advanced and impact on productivity. It can direct you to issues in a particular paddock that need your attention before they become too advanced and impact on productivity. Other technology described includes Green on brown weed sprays which use computers on sprayers to spray plants (weeds) on bare ground. It also includes the more sophisticated green on green technology where artificial intelligence fitted to cameras on sprayers allows herbicide application to specific weeds in a crop. Cameras scan the paddocks to recognise the weeds and then control the spraying in real time to spray only weeds and the dose required and not the whole paddock. This helps save money and protects the environment. Information from remote sensing devices locates the weed populations so that you know which paddocks to scan. The advantages and issues with minimum or no-till, controlled traffic farming (CTF) and stubble retention are also discussed.

Global crop production must substantially increase to meet the needs of a rapidly growing population. This is constrained by the availability of nutrients, water, and land. There is also an urgent need to reduce the negative environmental impacts of crop production. Collectively, these issues represent one of the greatest challenges of the twenty-first century. Sustainable cropping systems based on ecological principles are the core of integrated approaches to solve this critical challenge. This special issue provides an international basis for revealing the underlying mechanisms of sustainable cropping systems to drive agronomic innovations. It includes review and original research articles that report novel scientific findings on improvement in cropping systems related to crop yields and their resistance to biotic and abiotic stressors, resource use efficiency, environmental impact, sustainability, and ecosystem services.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Reliance on non-renewable resources is among the fundamental challenges to agricultural sustainability. Quantification of inputs in units of embodied fossil energy offers insight into sustainable use of these resources. Metrics of intensity, efficiency of non-renewable energy inputs to agriculture have been proposed for optimization in search of sustainability in the face of energy scarcity. Such analyses have found controversial results however, and further theoretical understanding is necessary. The research presented here focuses on approaches to sustainability targeting the semiarid northern Great Plains of North America. The 4 million ha of cropland fallowed in this region every year represent both a challenge to sustainability and an opportunity to address that challenge. Long identified as unsustainable when accomplished by tillage and without fertilizer input, the summerfallow-wheat crop production system is also energy-efficient by definitions that do not account for changes in soil fertility. It is shown here that accounting for lost soil N as an energy input to crop production partially resolves this paradox, but no strategy for energetic valuation of systems that build soil quality is apparent. Alternatives to summerfallow considered here include pulse crops (e.g. pea and lentil) grown for grain, forage, or as cover crops. In research conducted on farms already growing pulses, the largest effect on cropping system energy productivity was due to increased wheat yield rather than a reduction of inputs. In plot-scale research addressing a wider variety of production practices, neither system-level energy intensity nor productivity provided more insight into energy price exposure than basic economic analyses.

FAO’s best-selling 2011 publication, Save and Grow, proposed a new paradigm of agriculture, one that is both highly productive and environmentally sustainable. This new book looks at the application of “Save and Grow” practices and technologies to production of the world’s key food security crops – maize, rice and wheat. With examples drawn from developing countries worldwide, it shows how eco-friendly farming systems are helping smallholder producers to boost cereal yields, improve their incomes and livelihoods, conserve natural resources, reduce negative impacts on the environment, and build resilience to climate change. The book will be a valuable reference for policymakers and development practitioners guiding the transition to sustainable food and agriculture.
