| Key findings regarding the structure of trade for tomato, rape, and onion into Lusaka are (a) regional trade is an important part of Zambia’s fresh produce system, (b) supply chains for tomato, rape, and onion are short, (c) the role of the modern market system is very small, and (d) the role of urban agriculture in supplying Lusaka markets for these vegetables is also small, though it is meaningful in the case of rape. Main policy implications from this and related work are that (a) investments and policies to promote regional trade are relevant for the horticultural sector, not just food staples, (b) the traditional market system needs improved hard infrastructure linked to more collaborative public/private management models and improved coordination... |

| Ob verantwortungsvoller Tourismus, nachhaltiger Fisch oder regionale Lebensmittel – der Außer-Haus-Markt in Western Cape ist äußerst dynamisch und damit im landesweiten Vergleich auf der Überholspur. Erst kürzlich erfolgte die Einführung fair gehandelter Produkte auf dem heimischen Markt. Südafrika ist weltweit das erste Land, das Fair Trade Produkte von nun an nicht nur exportiert, sondern auch selbst konsumiert. Und ein Fair Trade Zertifizierungsprogramm für die Tourismusbranche ist in seiner Art einzigartig. Vor allem die Provinzregierung von Western Cape und die Stadtverwaltung von Kapstadt übernehmen hinsichtlich nachhaltiger Entwicklung eine Vorbildfunktion innerhalb Südafrikas. 2008 veröffentlichte die Provinzregierung ihren ersten... |

| With the political changes in South Africa in the early 1990s, the South African government introduced a reform process in the entire water sector with the goal of a more enhanced and equitable water management system. This paper analyzes existing water allocation situations and applies a nonlinear optimization model to investigate the optimal intra- and inter-regional allocations in the Middle Olifants sub-basin of South Africa. Results show higher benefit from inter-regional water allocation. Reducing water supply levels to conform to the sustainable water supply policy, it can be shown that although water supply is reduced by approximately 50%, total benefits from water are only reduced by 5% and 11% for inter- and intra-regional allocation regimes... |

| Unsustainable exploitation of wild animals is one of the greatest threats to biodiversity and to millions of people depending on wild meat for food and income. The international conservation and development community has committed to implementing plans for sustainable use of natural resources and has requested development of monitoring systems of bushmeat offtake and trade. Although offtake monitoring systems and indicators for marine species are more developed, information on harvesting terrestrial species is limited. Building on approaches developed to monitor exploitation of fisheries and population trends, we have proposed two novel indicators for harvested terrestrial species: the mean body mass indicator (MBMI) assessing whether hunters are relying... |

| Soil quality improvements provide an environment for plant nutrient uptake that impacts the development and yield of the crop. Thus, this study evaluated the effect of applied poultry composted organic manure (PCOM) on selected soil physical attributes and soil organic carbon content (SOC) under two tomatoes (UC82B and BESKE) varieties planted in succession. Three rates 0, 10 and 20 t ha-1 of compost were applied to two tomato varieties. The treatments were arranged in a randomized complete block design (split-plot layout). The soil physical parameters considered are - bulk density, aggregate stability, total porosity and SOC. It was observed that application of PCOM increased SOC, total porosity, aggregate stability and decreased the bulk density in the... |

| Information and communications technologies (ICTs) have spread rapidly over the past decade. There has been considerable interest in the effect of such technology on search costs, search behavior and welfare outcomes, particularly in developing countries. This paper investigates the impact of a new search technology, mobile phones, on traders’ search and marketing behavior in Niger. We construct a novel theoretical model of sequential search, in which traders engage in optimal search for the maximum sales price, net transport costs. The model predicts that the introduction of a new search technology, such as mobile telephones, will increase traders’ reservation sales prices and the number of markets over which they search. To test the predictions of the... |

| Kenya has been recognized globally as maize success story since the 1970s. Released on the eve of independence, Kenya’s first maize hybrid diffused faster than did hybrids in the U.S Corn Belt during the 1930s-1940s. In recent decades, policy researchers have lamented that earlier gains in maize productivity have not lived up to their potential. Claims of stagnating yields and stagnating adoption are offset here, at least in part, by longitudinal survey data showing rising yields and adoption rates on farms. Tegemeo survey data confirm that Kenya has reached its adoption ceiling years ago in the major maize producing zones of the country, and is near to doing so in other zones. Data show adoption rates topping 80% of farmers. |
