This study was intended to develop an understanding of producer preference for land-based carbon sequestration in agriculture. We conducted a mail survey to elicit producer choice to provide marketable carbon offsets by participating in different carbon credit programs characterized by varying...

Nutrient emissions from agricultural land are now widely recognized as one of the key contributors to poor water quality in local lakes, rivers and streams. Nutrient trading has been suggested as a regulatory tool to improve and protect water quality. However, farmers’ attitudes suggest that...

Climate change is a natural and dynamic phenomenon resulting from complex interrelationships between physical, environmental and human factors. The sustainability of life on earth depends partly on the ability of mankind to maintain this natural and balanced flow of such gases such as carbon...

Development is a human problem and is aimed at changing man and his economic, social, ecological environment. Throughout history, man has acquired new knowledge to shape his future. As human needs multiplied and became more complex, science and technology – processes of systematic inquiry for...

The Agricultural Production Survey (APS) is Statistics New Zealand’s vehicle for collecting important information about New Zealand’s primary production. It is an annual postal survey and covers land use, livestock and arable farming, horticultural and forestry production, and selected farm...

Food for all continues to be a key issue, especially in the developing world where every fifth person is chronically undernourished. India, a fast growing developing country has also experienced serious food shortages for example in the mid 1960s. Punjab, a small northern Indian state has...

Nitrogen is an important input to agricultural production but also detrimentally affects the environmental quality of air, soil and water. Identifying the determinants of nitrate pollution and in turn defining sensible performance indicators to design, enforce and monitor regulatory policies is...

This paper seeks to describe and discuss the impact that climate changes, and other challenges in terms of sustainability, have had on Africa and particularly on South Africa. It seeks to discuss the extent to which these changes directly and indirectly impact agriculture and the measures that...

Mathematical programming models suit policy makers' needs for assessing impacts of new policies and modellers' needs for new parameters, constraints and activities to represent the phenomenon under study. The AROPAj model aims at taking into account any geographical extension of the European...
