Institutional perspectives of land reclamation operations in Punjab: A case study of the Lower Chenab Canal (East) Circle Area AgEcon
Bandaragoda, Don Jayatissa; Rehman, Saeed ur.
The Directorate of Land Reclamation (DLR), which was set up in 1945, is a special unit of Punjab's Irrigation and Power Department for undertaking research and field operations to combat the problem of salinity. Approaching the end of five decades of existence, the directorate is yet to demonstrate its effectiveness in its assigned task; its inability to fully cope with the conditions of a fast changing irrigation environment makes this rather an illusive goal. In the selection of lands for reclamation, the Directorate is heavily dependent on the visual salinity survey (Thur Girdawari) carried out every year by the Irrigation Department's field staff. This visual survey appears to be a quick and cost-effective method of assessing surface salinity, but...

Agricultural Employment Trends in an Enlarged European Union: Does the CAP Reform/Introduction Matter? AgEcon
Baum, Sabine; Cook, Peter; Stange, Henriette; Weingarten, Peter.
In the course of economic development there is a general downward trend of agricultural employment, although structural change in agriculture is often delayed. In the EU-15, agricultural employment decreased by -2.3% p.a. (measured in regular persons) and -3.0% p.a. (measured in annual working units) between 1995 and 2000. In some of the new EU Member States, employment in agriculture plummeted in the early 1990s, whereas in others it increased during the first years of transition and has served as a social buffer in times of economic hardship. The most important determinants of agricultural employment changes are labor saving technical progress, the macroeconomic environment, the farm structure, socio-economic characteristics of the farmer and...

Water-resource and land-use issues AgEcon
Calder, Ian R..
This paper reviews perceived notions of the relationships between catchment land use and hydrology and explores whether much of the widely disseminated folklore, so often inextricably linked with issues of land use, is based on myth or reality. Gaps in our knowledge of the underlying processes in relation to land use and hydrology are identified. Our ability to apply this knowledge at different scales ranging from the plot to the catchment and regional scales are discussed and specific examples are drawn from Indian and African case studies. Methods for linking spatially distributed land-use hydrological models with economics and ecology through decision support systems are outlined and proposed as a framework for the integrated management of land and...

Foghorns to the Future: Using Knowledge and Transdisciplinarity to Navigate Complex Systems Ecology and Society
Cundill, Georgina N. R.; Rhodes University; gcundill@rides.cl; Fabricius, Christo; Rhodes University; c.fabricius@ru.ac.za; Marti, Neus; Autonomous University; neus@amauta.rcp.net.pe.
Complex systems are shaped by cross-scale interactions, nonlinear feedbacks, and uncertainty, among other factors. Transdisciplinary approaches that combine participatory and conventional methods and democratize knowledge to enable diverse inputs, including those from local, informal experts, are essential tools in understanding such systems. The metaphor of a “bridge” to overcome the divide between different disciplines and knowledge systems is often used to advocate for more inclusive approaches. However, there is a shortage of information and consensus on the process, methodologies, and techniques that are appropriate to achieve this. This paper compares two case studies from Peru and South Africa in which community-level assessments...

Environmental and social values of river water: examples from the Menik Ganga, Sri Lanka. AgEcon
Dissanayake, Priyanka; Smakhtin, Vladimir U..
Many decisions on water allocation in river basins are made on economic grounds. Environmental and social benefits of water should also be considered in river basin management, and attempts should be made to value them similarly. This is not a straightforward task and very few studies have directly addressed this issue to date. In this paper, the Menik Ganga (River) in southern Sri Lanka is used as a case study to attempt and evaluate the costs and benefits of environmental water allocations, referred to as ‘environmental flows’ (EF). In this study, a broad definition of EF is used: the components of EF evaluated include the requirements of the religious festival, the requirements of the Yala National Park, the requirements of the Pilinnawa Coastal Wetland...

ADOPTION OF MAIZE AND WHEAT TECHNOLOGIES IN EASTERN AFRICA: A SYNTHESIS OF THE FINDINGS OF 22 CASE STUDIES AgEcon
Doss, Cheryl R.; Mwangi, Wilfred; Verkuijl, Hugo; De Groote, Hugo.
This paper synthesizes the findings of 22 micro-level studies on technology adoption carried out by the International Maize and Wheat Improvement Center (CIMMYT) with national agricultural research systems in Ethiopia, Kenya, Tanzania, and Uganda from 1996-1999. The authors found that technology adoption is taking place across Eastern Africa but considerable scope remains to improve the productivity of smallholder agriculture in higher potential regions with high levels of adoption. Extension was the variable most highly correlated with technology adoption, and extension services continue to play an important role in disseminating information on new varieties and how to manage them. Despite the usefulness of the micro-study results, especially for priority...

Enhancing Student Learning Experiences and Providing Value to the Agribusiness Industry by Building the Industry-Institution Interface AgEcon
Foltz, John C.; Devadoss, Stephen.
This paper addresses agribusiness industry-institution interfaces, research-education linkages, and improving agribusiness education with opportunities such as agricultural students’ internships with agribusiness companies, conducting applied research, and finding opportunities for agribusiness educational seminars conducted by universities. The rationale for agribusiness internships is discussed, and agribusiness internship structure and planning is outlined. The potential benefits of a Departmental Advisory Board are listed, along with suggestions for implementing such a group. Applied agribusiness research opportunities including case studies and extension, outreach, or trade publications are highlighted, and examples of this type of work are discussed....

Introduction to exploring opportunities for advancing collaborative adaptive management (CAM): integrating experience and practice Ecology and Society
Galat, David L.; Department of Fisheries & Wildlife Sciences, University of Missouri; GalatD@missouri.edu; Berkley, Jim; U. S. Environmental Protection Agency; berkley.jim@epa.gov.
This Special Feature of Ecology and Society seeks to communicate a practitioner’s perspective on the application of collaborative adaptive management (CAM) to contemporary natural resource management problems. One goal is to create an ongoing mechanism for dialogue that can connect practitioners, researchers, and policy makers. The core 15 papers are grouped into 3 categories that: (1) describe lessons learned through the practice of applying CAM principles to a specific project or generalizing principles from outcomes of a specific project; (2) summarize lessons learned from the author’s extensive CAM experiences; and (3) seek to be instructive of one or more CAM principles through a survey, evaluation, or comparison of multiple...
