This monograph is part of a series of reports that explain how techniques of spatial analysis can be used to investigate poverty and environment links worldwide. It combines rural population distribution data contained in the global rural population database for the year 2000 with methods and results of the "Global agro-ecological assessment for agriculture in the 21st century," in order to estimate the distribution of the world's rural population by agricultural suitability class, land-use category and type of farming system.--Publisher's description.
Agricultural biostimulants are a group of substances or microorganisms, based on natural resources, that are applied to plants or soils to improve nutrient uptake and plant growth, and provide better tolerance to various stresses. Their function is to stimulate the natural processes of plants, or to enrich the soil microbiome to improve plant growth, nutrition, abiotic and/or biotic stress tolerance, yield and quality of crop plants. Interest in plant biostimulants has been on the rise over the past 10 years, driven by the growing interest of researchers and farmers in environmentally-friendly tools for improved crop performance. Improved crop production technologies are urgently needed to meet the growing demand for food for the ever-increasing global population by addressing the impacts of changing climate on agriculture. This book is of interest to researchers in agriculture, agronomy, crop and plant science, soil science and environmental science.
Intensifying water constraints threaten food security and nutrition. Thus, urgent action is needed to make water use in agriculture more sustainable and equitable. Irrigated agriculture remains by far the largest user of freshwater, but scarcity of freshwater is a growing problem owing to increasing demand and competition for freshwater resources. At the same time, rainfed agriculture is facing increasing precipitation variability driven by climate change. These trends will exacerbate disputes among water users and inequality in access to water, especially for small-scale farmers, the rural poor and other vulnerable populations. The State of Food and Agriculture 2020 presents new estimates on the pervasiveness of water scarcity in irrigated agriculture and of water shortages in rainfed agriculture, as well as on the number of people affected. It finds major differences across countries, and also substantial spatial variation within countries. This evidence informs a discussion of how countries may determine appropriate policies and interventions, depending on the nature and magnitude of the problem, but also on other factors such as the type of agricultural production system and countries’ level of development and their political structures. Based on this, the publication provides guidance on how countries can prioritize policies and interventions to overcome water constraints in agriculture, while ensuring efficient, sustainable and equitable access to water.
There is an urgent need to increase agricultural productivity in sub-Saharan Africa in a sustainable and economically-viable manner. Transforming risk-averse smallholders into business-oriented producers that invest in producing surplus food for sale provides a formidable challenge, both from a technological and socio-political perspective. This book addresses the issue of agricultural intensification in the humid highland areas of Africa – regions with relatively good agricultural potential, but where the scarce land resources are increasingly under pressure from the growing population and from climate change. In addition to introductory and synthesis chapters, the book focuses on four themes: system components required for agricultural intensification; the integration of components at the system level; drivers for adoption of technologies towards intensification; and the dissemination of complex knowledge. It provides case studies of improved crop and soil management for staple crops such as cassava and bananas, as well as examples of how the livelihoods of rural people can be improved. The book provides a valuable resource for researchers, development actors, students and policy makers in agricultural systems and economics and in international development. It highlights and addresses key challenges and opportunities that exist for sustainable agricultural intensification in the humid highlands of sub-Saharan Africa.

This edited volume establishes a forum for international experts to explore cutting-edge questions associated with the land use and biomass production. Topics include ‘do we have enough land, either primary or marginal, to accommodate future production of biomass?’, ‘how are farming decisions made in response to biomass incentives?’, ‘is the current bio-mass production socially, economically and environmentally sustainable?’, and ‘what are the main constraints currently limiting biofuel deployment?’ The expansion of biomass production is often at the cost of reduced land availability for food production and losses of areas with ecological functions such as forests and wetlands. This process often involves complex interplay of physical dynamics and human systems that are driven by numerous geographic and socio-economic factors at different scales. Thus, the state-of-the-art research on the land use issues surrounding the biomass production and its environmental impacts is important for informed land management decision making. This book will be of great use to researchers in land use management and biomass-based renewable energy, as well as practitioners.

This book provides a comprehensive understanding of the complex relationship between microbial symbionts and plants in the era of climate change. It focuses on the plant microbiome associated with different plant organs like roots, leaves, stems, fruit, and seeds, and showcases their significant role in the enhancement of crop yield and protection in a sustainable manner. Concomitantly, acumens to the most emerging trends in plant microbial research that includes rhizosphere engineering and metagenomics are also covered in this title. The association of microbial symbionts with the host offers a wide advantage in terms of acclimatization to varied environmental conditions. A large number of microbes such as cyanobacteria, PGPR, endophytes, and AMF have been shown to improve plant growth and production under the effect of various abiotic and biotic stresses. These microbial symbionts secrete several secondary metabolites, signaling molecules, and hydrolytic enzymes that play a multifarious role in improving plant growth and yield. Moreover, the symbionts have been known to regulate the host responses at the molecular level. Bioprospecting these microbial symbionts will provide an alternative to the chemical-based fertilizers and pave the path for the development of biofertilizers. The book is a suitable reading material for undergraduate and postgraduate students, researchers, and scientists working in the field of agricultural biotechnology, microbiology, mycology and plant pathology, and allied fields of plant and microbial sciences. The book in this context attempts to provide an integrative and exhaustive study as well as research material that would help the scientific community in wide respect.
