RICE AND WATER
Rice is eaten by about 3 billion people and is the most common staple
food of the largest number of people on earth (Maclean et al., 2002). In the
1960s, the combination of new high‐yielding varieties with increased input
use, such as water, fertilizer, and biocides (agrochemicals to protect the crop
from pests, diseases, and weeds), initiated a rapid increase in productivity
that is called the ...
Early participation in the American College and University Presidents’ Climate Commitment
Purpose – The purpose of this paper is to describe and analyze those US campuses that became
signatories of the American College and University Presidents Climate Commitment (ACUPCC) during
the charter membership period of December 2006 through September 15, 2007.
Design/methodology/approach – The paper draws on literature in organizational change,
organizational learning, and innovation ...
Adaptation to climate change in Ethiopia and South Africa: options and constraints
Climate change is expected to adversely affect agricultural production in Africa. Because
agricultural production remains the main source of income for most rural communities in
the region, adaptation of the agricultural sector is imperative to protect the livelihoods of the
poor and to ensure food security. A better understanding of farmers’ perceptions of climate
change, ongoing adaptation ...
Business and climate change: Initial explorations in South Africa
Climate change is one of a complex array of risks facing the planet and society. It is argued that adaptation to and mitigation of climate change will be required to avert or reduce adverse impacts. Governments are developing climate change adaptation (CCA) strategies. The business community is also stirring to the need to adapt to as well as mitigate climate change, but progress has been slow, ...
CLIMATE CHANGE VULNERABILITY ASSESSMENTS: AN EVOLUTION OF CONCEPTUAL THINKING
Vulnerability is an emerging concept for climate science and policy. Over the past decade,
efforts to assess vulnerability to climate change triggered a process of theory development and assessment practice, which is reflected in the reports of the Intergovernmental Panel on Climate Change
(IPCC). This paper reviews the historical development of the conceptual ideas underpinning assessments
Assessing the vulnerability of food crop systems in Africa to climate change
Africa is thought to be the region most vulnerable to the impacts of climate
variability and change. Agriculture plays a dominant role in supporting rural livelihoods
and economic growth over most of Africa. Three aspects of the vulnerability of food crop
systems to climate change in Africa are discussed: the assessment of the sensitivity of crops
to variability in climate, the adaptive capacity ...
Influences of climate on aflatoxin producing fungi and aflatoxin contamination
Aflatoxins are potent mycotoxins that cause developmental and immune system suppression, cancer, and death. As a result of regulations intended to reduce human exposure, crop contamination with aflatoxins causes significant economic loss for producers, marketers, and processors of diverse susceptible crops. Aflatoxin contamination occurs when specific fungi in the genus Aspergillus infect crops. ...
Impact pathway evaluation: an approach for achieving and attributing impact in complex systems
Agricultural development is fundamentally a social process in which people construct solutions to their problems, often by modifying both new technologies and their own production systems to take advantage of new opportunities offered by the technologies. Hence, agricultural change is an immensely complex process, with a high degree of non-linearity. However, current ‘best practice’ economic ...
