A three-year project was funded by the BMZ/GIZ to examine the benefits of integrating aquaculture and small scale irrigation by identifying improved water allocation and management strategies under current and future climate change scenarios. An integrated modeling approach was adopted to…
Agriculture is one of the biggest sources of greenhouse gases. Rice production has been identified as one of the major sources of greenhouse gases, especially methane. However, data on the contributions of rice towards greenhouse gas emissions in tropical Africa are limited. In Zimbabwe, as in…
This paper examines the impact of government sectoral expenditure on economic growth in Malawi. Using time series data from 1980 to 2007, cointegration analysis in the context of an error correction model was employed to estimate the growth effects of government expenditures in agriculture,…
This paper investigates causal relationships between exports, imports, and economic growth in Malawi over the period 1961-2010. These relationships are examined using the Johansen frameworks for co-integration whereas the Vector Error Correction (VECM) framework is further used to provide…
This paper presents a methodological framework for revitalising small-scale irrigation schemes which are no longer performing well due to a combination of infrastructural, social-economic, institutional and governance problems, among others. The framework was developed as part of a project to…
The world’s climate is changing rapidly and Africa will be severely affected by this, not only because of the effects on ecosystems but also because of the low adaptive capacity of communities due to poverty and lack of infrastructure, services, and appropriate policies to support adaptation…
The knowledge of runoff discharged by a catchment at its outlet is important for water accounting and water allocation to competing uses. Runoff generated by a catchment is important in determining the catchment water balance, estimating pollutant loads, and quantifying sediment yield and…
An evaluation of available opportunities to revive irrigation on a long abandoned irrigation scheme in a dry region of Zimbabwe is presented by assessing water availability at catchment level. The aim is to enhance the livelihoods, income and nutrition of the communities that depend on the…
Agriculture plays a crucial role in food security and poverty reduction in Mozambique, contributing around 25 percent of the country’s Gross Domestic Product (GDP). However, despite the considerable agro-ecological potential and the need for increased production, agricultural productivity…
The 2013 Global Hunger Index (GHI) report-the eighth in an annual series- presents a multidimensional measure of national, regional, and global hunger. It shows that the world has made some progress in reducing hunger since 1990, but still has far to go. The 2013 GHI report focuses on resilience…
This thesis deals with the politicized struggles for land in South Africa’s Limpopo Province. With land having been an essential part of colonial and apartheid segregation policies and practice – with 87% of land appropriated by whites –, a land reform programme was imperative after the African…
It is well known that land-use changes influence the hydrological cycle and that those changes in the hydrological cycle influence land use. The sophisticated spatial dynamic planning tools that have been developed in the last decades to support policy makers in the decision making process do…
