carbon footprint; climate; climate change; crop models; crop production; cropping systems; crops; decision support systems; diet; education; farmers; food production; food security; nutrients; production technology; risk assessment; simulation models; temperature
Abstract:
... Food production systems in the next decades need to adapt, not only to increase production to meet the demand of a higher population and changes in diets using less land, water and nutrients, but also to reduce their carbon footprint and to warmer temperatures and altered precipitation patterns resulting from climate change. Crop simulation models offer a research tool for evaluating trade-offs of ...

Subject:
biofortification; breeding methods; developing countries; food crops; food security; genetically modified organisms; hunger; nutrients
Abstract:
... Biofortification, the process of breeding nutrients into food crops, provides a sustainable, long-term strategy for delivering micronutrients to rural populations in developing countries. Crops are being bred for higher levels of micronutrients using both conventional and transgenic breeding methods; several conventional varieties have been released, while additional conventional and transgenic va ...

3. Delivering food security without increasing pressure on land

Author:
Smith, Pete

ISSN:
2211-9124
Subject:
ecosystem services; food production; food security; waste reduction
Abstract:
... The challenge of feeding 9 to 10 Billion people by 2050 may seem like a big enough challenge in itself, but we also need to achieve this feat whilst, at the same time, reducing adverse impacts of food production on a whole range of ecosystem services. One suggested response is “sustainable intensification” which entails delivering safer, nutritious food from the same area whilst maintaining ecosys ...

4. From complexity to food security decision-support: Novel methods of assessment and their role in enhancing the timeliness and relevance of food and nutrition security information

Author:
Mock, Nancy; Morrow, Nathan; Papendieck, Adam

ISSN:
2211-9124
Subject:
communications technology; data collection; decision making; food security; household surveys; issues and policy; nutrition
Abstract:
... Food and Nutrition Security Information (FNSI) is a critical tool for achieving food and nutrition security, yet FNSI efforts to date have not produced the intended impacts on policy and program decision making, largely due to shortcomings in available technologies and frameworks. The article reviews the evolution of FNSI efforts in the context of emerging technology and data collection techniques ...

5. Generating evidence on individuals' experience of food insecurity and vulnerability

Author:
Quisumbing, Agnes R.

Global food security 2013 v.2 no.1 pp. 50-55
ISSN:
2211-9124
Subject:
agricultural productivity; coping strategies; food security; gender; Bangladesh; Ethiopia; Uganda
Abstract:
... Many indicators of food security and vulnerability are reported at the household level, preventing policymakers from identifying how differences among individuals within the household affect individual food security and vulnerability. Using examples from three recent studies from Uganda, Bangladesh, and Ethiopia, the paper illustrates how using individual – rather than household-level measures all ...

6. Towards better measurement of household food security: Harmonizing indicators and the role of household surveys

Author:
Carletto, Calogero; Zezza, Alberto; Banerjee, Raka

ISSN:
2211-9124
Subject:
data collection; food security; household surveys; monitoring; nutrition; periodicity; stakeholders
Abstract:
... A variety of indicators are currently used for food security analysis, monitoring, and programming, and most agencies have their preferred variant on methods of data collection, aggregation, and analysis. This lack of consensus is reflected in an inefficient multiplicity of survey instruments collecting information on various dimensions of food and nutrition security, with tremendous variation in ...

7. Towards overcoming the food consumption information gap: Strengthening household consumption and expenditures surveys for food and nutrition policymaking

Subject:
food consumption; food security; household consumption; household surveys; households; information processing; nutrition assessment; nutrition information; nutrition policy; questionnaires; stakeholders
Abstract:
... The dearth of nationally representative dietary assessment studies continues to severely constrain the nutrition evidence base and throttle the pace of global progress in improving nutrition. Despite their shortcomings, household consumption and expenditures surveys (HCESs) are increasingly being used to address the food and nutrition information gap because they contain a great deal of informatio ...

Abstract:
... The challenges facing agriculture in China are probably more severe than ever before. We have developed an integrated technology system in which the focus is on achieving both high crop productivity and high resource use efficiency (“double high” technology system) to ensure food security and environmental sustainability. The components comprise (1) significantly increased grain-yield through high ...
