Agricultural sustainability and food security

Importance of Animals in Agricultural Sustainability and Food Security.

A conservative projection shows the world's population growing by 32% (to 9.5 billion) by 2050 and 53% (to 11 billion) by 2100 compared with its current level of 7.2 billion. Because most arable land worldwide is already in use, and water and energy also are limiting, increased production of food will require a substantial increase in efficiency. In this article, we highlight the importance of ...

Rapid emergence of pathogens in agro-ecosystems: global threats to agricultural sustainability and food security.

Agricultural ecosystems are composed of genetically depauperate populations of crop plants grown at a high density and over large spatial scales, with the regional composition of crop species changing little from year to year. These environments are highly conducive for the emergence and dissemination of pathogens. The uniform host populations facilitate the specialization of pathogens to parti...

Agricultural Aid and Food Security in Africa

This paper investigates the effects of agricultural aid on food security in African countries during the the 1990 to 2012 period. Defining food security as increases in agricultural productivity and controlling for a large number of covariates, we find that agricultural aid, at the aggregate level, aid to the agricultural sector has positive and statistically significant effect on food security...

Food security and food sustainability: reformulating the debate

The notion of food security has an important history as a key concept for 20th-century policymakers. Two overarching perspectives on food security are identified. One centred on raising production as the core answer to under-consumption and hunger. The other is an emerging perspective, more social and ecological, accepting the need to address a complex array of problems, not just production. Th...
