This book explains how a former net food exporting Nepal has become a net food importing country due to a lack of an integrated system-wide approach to planning and governance of agriculture and natural resources. It demonstrates how various components of the food system, such as agronomy, agrobiodiversity, plant health, post-harvest management, livestock and fisheries, and socio-economics including marketing and trade, have been managed in sectoral silos, crippling the very foundations of food systems innovations. The book also explores ways to tackle climate change impacts while considering gender, social equity, conservation agriculture practices, and crop modeling as cross-cutting themes. This book utilizes Nepal as a case study in relation to wider questions of food security and livelihoods facing South Asia and synthesizes lessons that are relevant to the Global South where countries are struggling to harmonize and integrate natural resources management for sustainable and effective food security outcomes. As such, it significantly contributes to the knowledge toward achieving various United Nations Sustainable Development Goals.

Although the "greenhouse effect" and "global climate change" have been the subjects of scientific scrutiny for many decades, only recently have they received widespread public attention. Two major events helped generate this attention. First, in 1990 the Intergovernmental Panel on Climate Change (IPCC) published its findings on the science, impacts and policy implications of climate change. The findings of the IPCC, prepared and reviewed extensively by the world's leading experts in the field, confirmed that the increasing atmospheric concentrations of "greenhouse" gases, such as carbon dioxide, methane, nitrous oxide and the chlorofluorocarbons, could cause the world to warm and sea level to rise. Second, in 1992 the United Nations Conference on Environment and Development (UNCED) inRio de Janeiro focussed the attention of the world's national governments, as well as organisations and individuals outside the governments, on the threat of global climate change. The Framework Convention on Climate Change (FCCC), signed by nations at UNCED, reflects both the concern about the effects of climate change and the urgent need for action to prevent or reduce its potential impacts, particularly with respect to the vulnerable developing countries of the world. Bangladesh ratified the FCCC on 15 April 1994. The countries that have signed and ratified the FCCC are obligated to report to the Conference of the Parties (CoP) to the Convention on a number of inter related issues.

Africa's high dependence upon natural resources makes the continent particularly vulnerable to changes in the availability of water as a result of climate changes. In this study, the vulnerability of water resources to environmental change is assessed on a river/lake/groundwater basin scale for the Southern, Eastern, Western and Northern African regions.
