Abstract: The environment and security literature has argued that freshwater scarcity often leads to inter-state conflict, and possibly acute violence. The contention, however, ignores the long history of hydro-political cooperation exemplified by hundreds of documented agreements. Building on a theory that considers the relationship between scarcity and hydro-political cooperation, this paper empirically investigates why treaties are negotiated for some rivers and between some riparians, and not others. The paper suggests that long-term water scarcity has a significant influence on levels of cooperation. Additional variables considered include trade, level of governance among the riparian states, and the geography of the river. Findings confirm that cooperation and scarcity embody a concave (inverted U curve) relationship. Governance has a positive impact on cooperation. In addition, riparians may either arrange the use of their scarce water resources via a treaty or trade (and indirectly exchange [virtual] water). Scarcity, governance, and trade were found to be most salient in explaining levels of cooperation while geography is significant in some of the estimates.
'This is a well researched, thorough and impressive work on climate change and agriculture in Africa. I recommend it to students, researchers and practitioners working on climate change issues' Jabavu Clifford Nkomo, senior programme specialist, IDRC This landmark book encompasses a comprehensive assessment of the potential economic impacts of future climate change, and the value of adaptation measures in Africa for different zones, regions, countries and farm types. Researchers developed and applied multiple analytical procedures to assess quantitatively how climate affects current agricultural systems in Africa, enabling them to predict how these systems may be affected in the future by cl...
Irrigation has been and will continue to be an agricultural and rural investment priority. Development of the irrigation sector faces multiple challenges, including water scarcity and degradation, competition over shared resources, and the impact of climate change. Innovations are needed to address these challenges, as well as emerging needs, and to promote productive, equitable and sustainable water management. These guidelines, produced by an inter-agency team, highlight experiences and lessons learned from global irrigation investment operations. They introduce innovative approaches, tools and references, and provide practical guidance on how to incorporate or apply them at each stage of the investment project cycle. The guidelines will be a useful resource for national and international professionals involved in irrigation investment operations.
This paper summarizes the methods and findings of the hydrological assessment component of the project studying likely impacts of climate change on water resources and agriculture in Africa. The first phase of the study used a version of a conceptual rainfall-runoff model called WatBal (Water Balance) applied to gridded data to simulate changes in soil moisture and runoff across the whole continent of Africa rather than to any particular catchment or water resource system. The model inputs were the climate variables of the 1961-90 climatology and physiological parameters (such as soil properties and land use) derived from global datasets for each of the 0.5 degree latitude/longitude cells ac...
The specific focus of this seminal work is on the economic impact of climate change on agriculture world wide, and how faced with the resultant environmental alterations, agriculture might adapt under varied and varying conditions. Enhanced with a detailed and comprehensive index, Climate Change and Agriculture is highly recommended for academic library environmental studies and economic studies reference collections and supplemental reading lists. The Midwest Book Review Despite its great importance, there are surprisingly few economic studies of the impact of climate on agriculture and how agriculture can adapt under a variety of conditions. This book examines 22 countries across four cont...
Abstract: This paper examines the export performance of 99 countries over 1995-2004 to understand the relative roles of export growth through "discovery" of new products and growth during post-discovery phases of the export product cycle - acceleration and maturation - in existing markets and expansion into new geographic markets. The authors find that expanding existing products in existing markets (growth at the intensive margin) has greater weight in export growth than diversification into new products and new geographic markets (growth at the extensive margin). Moreover, growth into new geographic markets appears to be more important than discovery of new export products in explaining export growth. Of particular importance is whether an exporting country succeeds in reaching more national markets that are already importing the product it makes. This geographic index of market penetration is a powerful explanatory variable of export performance. This suggests that governments should not focus solely or even primarily on the discovery channel, but also seek to identify and address market failures that are constraining exporters in subsequent phases of the export cycle.
Abstract: This paper investigates the extent of China's export boom in machinery and analyzes trade in components and finished machinery between China and Southeast Asia. China has increased its world market share in machinery exports. The median relative unit value of its finished machinery exports has also risen. Yet the author finds no evidence that China's expansion in the world machinery market has squeezed the market shares of Southeast Asian machinery exports. Instead, components made by Southeast Asian countries are increasing in unit value and gaining market share in China.
