Mid-summer Dry Spell and Agriculture in Jamaica


Book Description

At the beginning of the 21st century, Jamaica stands in a precarious situation which could have serious implications for the island's future. This stress may not have derived from a decrease in precipitation due to climate change, as well as a lack of interest in farming from smallholder farmers, which has become increasingly unsustainable. Younger Jamaicans have rejected farming as a career and instead opted for quick cash or migration out of the country in the hope of making their wealth elsewhere in the world. Thus, crop yields are at risk due to a smaller agricultural workforce. With decreasing labor rates and the current international economic crisis, the need for a high agricultural efficiency is greater than ever. Annual yields are also affected climatologically by a mid-summer atmospheric phenomenon called the Mid-Summer Dry Spell (MSD), resulting in bimodal rainy seasons in April-June and August-November. Understanding how rainfall affects crop production is a primary goal of this research. To accomplish this, a three part analysis will be conducted utilizing correlations between rainfall and crop yield, mapping with Geographic Information Systems (GIS), and analysis of how the MSD impacts brightness, greenness and wetness of vegetation.







Climate Change and Agriculture in Jamaica


Book Description

ctives of the study are: (i) to review current knowledge on vulnerability, past trends in climate, and impacts of climate variability and change on agriculture sector, and (ii) to explore technical and policy alternatives in order to cope with and adapt to impacts of climate variability and change more effectively. The study identified what the potential impacts are, considered what interventions are appropriate, and if and where they should occur. The scope of the study focused on broader policy directions and investment priorities in relation to climate change adaptation. The first two chapters of this book present overall background on the agriculture sector and vulnerability context. Chapter 2 specifically presents vulnerability of agro-ecosystems and food production systems in both temporal and special dimensions. Chapter 3 elaborates on the nature of climate variability and expected future changes in climate. The past trends in climate were described based on observation, analysi

Geography of Climate Change


Book Description

Climate change is one of the inescapable themes of current times. Climate change confronts society in issues as diverse as domestic and international political debate and negotiation, discussion in the media and public opinion, land management choices and decisions, and concerns about environmental, social and economic priorities now and for the future. Climate change also spans spatial, temporal and organisational scales, and has strong links with nature-society relationships, environmental dynamics, and vulnerability. Understanding the full range of possible consequences of climate change is essential for informed decision making and debate. This book provides a collection of chapters that span environmental, social and economic aspects of climate change. Together the chapters provide a diverse and contrasting series that highlights the need to analyze, review and debate climate change and its possible impacts and consequences from multiple perspectives. The book also is intended to promote discussion and debate of a more integrated, inclusive and open approach to climate change and demonstrates the value of geography in addressing climate change issues. This book was originally published as a special issue of Annals of the Association of American Geographers.
