This is further motivated by the recognition that the road network constitutes the single largest asset owned by the Government, and a less than optimal system of the management and maintenance of that asset generally results in huge losses for the national economy. In order to ensure management and maintenance of the PFR, the government is introducing the OPRC concept. The OPRC is a concept is a contracting approach in which the service provider is paid not for ‘inputs’ but rather for the results of the work executed under the contract i.e. the service provider’s performance under the contract. The initial phase of the project, supported by the World Bank will be implementing the Improved Rural Connectivity Project (IRCP) in some selected districts of Central, Eastern, Northern, Luapula, Southern and Muchinga Provinces. The project will be implemented in Eastern Province for a period of five (5) years from 2020 to 2025 using the Output and Performance Road Contract (OPRC) approach. GRZ thus intends to roll out the OPRC on the PFR Network covering a total of 14,333Kms country-wide.

The published version of this article is available at https://doi.org/10.1071/mf18132 Running title: Optimizing hydropower with ecosystem services # Corresponding author. Prof Ian G Cowx, Hull International Fisheries Institute, University of Hull, Hull HU67RX, UK. email: [email protected] 1 Abstract Fisheries are an important resource in Zambia, but are experiencing overexploitation and are under increasing pressure from external development activities that are compromising river ecosystem services and functioning. One such system is the Kafue Flats floodplain, which is under threat from hydropower development. This paper reviews the impact of potential hydropower development on the Kafue Flats floodplain and explores mechanisms to optimise the expansion of hydropower whilst maintain the ecosystem functioning and services the floodplain delivers. Since completion of the Kafue Gorge and Itezhi-tezhi dams, seasonal fluctuations in the height and extent of flooding have been suppressed. This situation is likely to get worse with the proposed incorporation of a hydropower scheme into Itezhi-tezhi dam, which will operate under a hydropeaking regime. This will have major ramifications for the fish communities and ecosystem functioning and likely result in the demise of the fishery along with destruction of the wetlands and associated wildlife.

  • Agrarian Changes in the Nyimba District of Zambia
    7 Agrarian changes in the Nyimba District of Zambia Davison J Gumbo, Kondwani Y Mumba, Moka M Kaliwile, Kaala B Moombe and Tiza I Mfuni Summary Over the past decade issues pertaining to land sharing/land sparing have gained some space in the debate on the study of land-use strategies and their associated impacts at landscape level. State and non-state actors have, through their interests and actions, triggered changes at the landscape level and this report is a synthesis of some of the main findings and contributions of a scoping study carried out in Zambia as part of CIFOR’s Agrarian Change Project. It focuses on findings in three villages located in the Nyimba District. The villages are located on a high (Chipembe) to low (Muzenje) agricultural land-use gradient. Nyimba District, which is located in the country’s agriculturally productive Eastern Province, was selected through a two-stage process, which also considered another district, Mpika, located in Zambia’s Muchinga Province. The aim was to find a landscape in Zambia that would provide much needed insights into how globally conceived land-use strategies (e.g. land-sharing/land-sparing trajectories) manifest locally, and how they interact with other change processes once they are embedded in local histories, culture, and political and market dynamics. Nyimba District, with its history of concentrated and rigorous policy support in terms of agricultural intensification over different epochs, presents Zambian smallholder farmers as victims and benefactors of policy pronouncements. This chapter shows Agrarian changes in the Nyimba District of Zambia • 235 the impact of such policies on the use of forests and other lands, with agriculture at the epicenter.

  • Can Design Thinking Be Used to Improve Healthcare in Lusaka Province, Zambia?
    INTERNATIONAL DESIGN CONFERENCE - DESIGN 2014 Dubrovnik - Croatia, May 19 - 22, 2014. CAN DESIGN THINKING BE USED TO IMPROVE HEALTHCARE IN LUSAKA PROVINCE, ZAMBIA? C. A. Watkins, G. H. Loudon, S. Gill and J. E. Hall Keywords: ethnography, design thinking, Zambia, healthcare 1. Background ‘Africa experiences 24% of the global burden of disease, while having only 2% of the global physician supply and spending that is less than 1% of global expenditures.’ [Scheffler et al. 2008]. Every day the equivalent of two jumbo jets full of women die in Childbirth; 99% of these deaths occur in the developing world [WHO 2012]. For every death, 20 more women are left with debilitating conditions, such as obstetric fistula or other injuries to the vaginal tract [Jensen et al. 2008]. In the last 50 years, US$2.3 trillion has been spent on foreign aid [Easterly 2006]; US$1 trillion in Africa [Moyo 2009]. Despite this input, both Easterly and Moyo argue there has been little benefit. Easterly highlights that this enormous donation has not reduced childhood deaths from malaria by half, nor enabled poor families access to malaria nets at $4 each. Hodges [2007] reported that although equipment capable of saving lives is available in developing countries, more than 50% is not in service. Studies have asked why this should be so high [Gratrad et al. 2007], [Dyer et al. 2009], [Malkin et al. 2011] the majority focussing on medical equipment donation. They suggest that it is not feasible to directly donate equipment from high to low-income settings without understanding how the receiving environment differs from that which it is designed for.

    IWMI Research Report Evaluating the Flow Regulating Functions of Natural Ecosystems 148 in the Zambezi River Basin Matthew McCartney, Xueliang Cai and Vladimir Smakhtin Research Reports The publications in this series cover a wide range of subjects—from computer modeling to experience with water user associations—and vary in content from directly applicable research to more basic studies, on which applied work ultimately depends. Some research reports are narrowly focused, analytical and detailed empirical studies; others are wide-ranging and synthetic overviews of generic problems. Although most of the reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each report is reviewed internally by IWMI staff, and by external reviewers.
