Precision farming enables agricultural management decisions to be tailored spatially and temporally. Site-specific sensing, sampling, and managing allow farmers to treat a field as a heterogeneous entity. Through targeted use of in- puts, precision farming reduces waste, thereby cutting both private variable costs and the environmental costs such as those of agrichemical residuals. At present, large farms in developed countries are the main adopters of pre- cision farming.
In this review, we examine the debate surrounding the role for organic agriculture in future food production systems. Typically represented as a binary organic–conventional question, this debate perpetuates an either/or mentality. We question this framing and examine the pitfalls of organic–conventional cropping systems comparisons. The review assesses current knowledge about how these cropping systems compare across a range of metrics related to four sustainability goals: productivity, environmental health, economic viability, and quality of life.
Agricultural biotechnology and, specifically, the development of genetically modified (GM) crops have been controversial for several reasons, including concerns that the technology poses potential negative environmental or health effects, that the technology would lead to the (further) corporatization of agriculture, and that it is simply unethical to manipulate life in the laboratory. GM crops have been part of the agricultural landscape for more than 15 years and have now been adopted on more than 170 million hectares (ha) in both developed countries (48%) and developing countries (52%).
International agricultural research is often motivated by the potential benefits it could bring to smallholder farmers in developing countries. A recent experimental literature has emerged on why innovations resulting from such research, which often focuses on yield enhancement, fail to be adopted due to either external or internal constraints. This article reviews this literature, focusing on the traits of the different technologies and their complexity and distinguishing between yield-enhancing, variance-reducing, and water- or labor-reducing technologies.
Food systems contribute 19%–29% of global anthropogenic greenhouse gas (GHG) emissions, releasing 9,800–16,900 megatonnes of carbon dioxide equivalent (MtCO2e) in 2008. Agricultural production, including indirect emissions associated with land-cover change, contributes 80%–86% of total food system emissions, with significant regional variation. The impacts of global climate change on food systems are expected to be widespread, complex, geographically and temporally variable, and profoundly influenced by socioeconomic conditions.
The challenges of providing food security for the developing world have perhaps never been so extreme, with the introduction of new technologies being matched by land degradation, water concerns and the often uncertain impacts of a changing climate. In short, we will need to produce more food on less land. Adding to the problem is the distrust and fear around some new technologies – particularly biotechnologies – that have created a divide between scientists and farmers, decision makers and the public. There have been many attempts to bridge these divides, but few success stories.
Though Odisha is India’s top sweetpotato-producing state, most farmers grow low-yielding varieties of limited nutritional value. The Odisha Directorate of Horticulture and the International Potato Center (CIP) spent four years promoting improved varieties and good agricultural practices in four districts of Odisha, resulting in a 25 per cent growth in the area dedicated to the crop, a 17 per cent increase in farm productivity, and a 40 per cent increase in farmer incomes within the project areas; as well as the introduction of a nutritious, orange-fleshed sweetpotato variety.
Capacity building for integrating gender in research and development (R&D) on agricultural innovations often remains with organizing single gender training. Alternatively, it is often limited to hiring a gender specialist to allocate a small amount of her/his time to the project. This has proofed to be ineffective and a heavy burden for gender specialists. This success story presents an innovative approach to capacity development, which successfully changed agricultural researchers’ attitude to gender in Southeast Asia, with a specific focus in Vietnam.
A network of women farmers’ leaders is set to drive widespread adoption of innovations and technologies across India. The International Rice Research Institute (IRRI), together with the Department of Biotechnology of India’s Ministry of Science and Technology, are training women farmer leaders on advanced rice production and soft skills to help boost food security in India.
The Water Resources Department, Government of Maharashtra, responsible for building infrastructure and delivering water to farmers and other users, has so far created irrigation potential of about 5.3. million hectares and the current utilization is about 76%. About 5000 Water User Associations (WUAs) have been established to manage the water supply within their designated areas. However, the water use efficiency and productivity is adversely impacting the overall water security of the state.
