It is extremely important for biodiversity conservation that protected areas are resilient to a range of potential future perturbations. One of the least studied influences on protected area resilience is that of disease. We argue that wildlife disease (1) is a social-ecological problem that must be approached from an interdisciplinary perspective; (2) has the potential to lead to changes in the identity of protected areas, possibly transforming them; and (3) interacts with conservation both directly (via impacts on wild animals, livestock, and people) and indirectly (via the public, conservation management, and veterinary responses). We use southern African protected areas as a case study to test a framework for exploring the connections between...

Adaptive Analysis of Locally Complex Systems in a Globally Complex World
Provedor de dados: 7
Autores: Lynam, Timothy; Tropical Resource Ecology Program, University of Zimbabwe; tlynam@science.uz.ac.zw.
Zambezi Valley agro-ecosystems are environmentally, economically, and institutionally variable. This variability means that it is not possible to measure everything necessary to develop a predictive understanding of them. In particular, because people and their environments are constantly changing, what was measured yesterday may change by tomorrow.  Here, I describe elements of the approach that I have developed to address this problem. Called DAAWN, for Detail as and When Needed, the approach advocates an iterative and multiscaled methodology in which we first capture as broad an understanding of the system as possible and then use awareness developed at this scale to identify where to focus subsequent, more detailed, investigations. Because we cannot...

Scale Mismatches in Social-Ecological Systems: Causes, Consequences, and Solutions
Provedor de dados: 7
Autores: Cumming, Graeme S; University of Florida; graeme@botzoo.uct.ac.za; Cumming, David H. M.; University of Zimbabwe; cumming@icon.co.zw; Redman, Charles L; Arizona State University; charles.redman@asu.edu.
Scale is a concept that transcends disciplinary boundaries. In ecology and geography, scale is usually defined in terms of spatial and temporal dimensions. Sociological scale also incorporates space and time, but adds ideas about representation and organization. Although spatial and temporal location determine the context for social and ecological dynamics, social-ecological interactions can create dynamic feedback loops in which humans both influence and are influenced by ecosystem processes. We hypothesize that many of the problems encountered by societies in managing natural resources arise because of a mismatch between the scale of management and the scale(s) of the ecological  processes being managed. We use examples from southern Africa and the...

To help integrated natural resource management (INRM) research "deliver the goods" for many of the world's poor over a large area and in a timely manner, the authors suggest a problem-solving approach that facilitates the scaling out of relevant agricultural practices. They propose seven ways to foster scaling out: (1) develop more attractive practices and technologies through participatory research (2) balance supply-driven approaches with resource user demands, (3) use feedback to redefine the research agenda, (4) encourage support groups and networks for information sharing, (5) facilitate negotiation among stakeholders, (6) inform policy change and institutional development, and (7) make sensible use of information management tools, including models...

Scenario planning is increasingly recognized as a useful tool for exploring change in social-ecological systems on decadal to centennial time horizons. In environmental decision making, scenario development tends to include participatory methods for engaging stakeholders and is conducted at multiple scales. This paper presents insights from participatory scenario development in two separate multiscale environmental assessments. We find that, to engage stakeholders at multiple scales, it is important that the issues explored at each scale be relevant and credible to stakeholders at that scale. An important trade-off exists between maintaining relevance to stakeholders at different scales and maintaining consistency across scales to allow for comparison of...

Evaluating Responses in Complex Adaptive Systems: Insights on Water Management from the Southern African Millennium Ecosystem Assessment (SAfMA)
Provedor de dados: 7
Autores: Bohensky, Erin; University of Pretoria; ebohensky@zoology.up.ac.za; Lynam, Timothy; University of Zimbabwe; tlynam@science.uz.ac.zw.
Ecosystem services are embedded in complex adaptive systems. These systems are riddled with nonlinearities, uncertainties, and surprises, and are made increasingly complex by the many human responses to problems or changes arising within them. In this paper we attempt to determine whether there are certain factors that characterize effective responses in complex systems. We construct a framework for response evaluation with three interconnected scopes or spatial and temporal domains: the scope of an impact, the scope of the awareness of the impact, and the scope of the power or influence to respond. Drawing from the experience of the Southern African Millennium Ecosystem Assessment (SAfMA), we explore the applicability of this framework to the example of...

The Incomati River Basin is shared by Mozambique, South Africa, and Swaziland. In August 2002, the groundbreaking &amp;#8220;Tripartite Interim Agreement on Water Sharing of the Maputo and Incomati Rivers&amp;#8221;  (the IncoMaputo agreement) was signed. Following reports that the use, availability, and adequacy of information posed problems for future decision making on this transboundary river, the Delft University of Technology initiated a 6-month study in 2003 in which 25 southern African researchers and officials were interviewed. The Joint Incomati Basin Study (Phase I from 1992&amp;#8211;1995, and Phase II from 2000&amp;#8211;2001) formed a central component in the investigation, because it was viewed by the parties involved as a successful...

Spatial Modeling of Risk in Natural Resource Management
Provedor de dados: 7
Autores: Jones, Peter; CIAT (International Center for Tropical Agriculture); p.jones@cgiar.org; Thornton, Philip K; International Livestock Research Institute; P.Thornton@cgiar.org.
Making decisions in natural resource management involves an understanding of the risk and uncertainty of the outcomes, such as crop failure or cattle starvation, and of the normal spread of the expected production. Hedging against poor outcomes often means lack of investment and slow adoption of new methods. At the household level, production instability can have serious effects on income and food security. At the national level, it can have social and economic impacts that may affect all sectors of society. Crop models such as CERES-Maize are excellent tools for assessing weather-related production variability. WATBAL is a water balance model that can provide robust estimates of the potential growing days for a pasture. These models require large...

Late Quaternary climatic changes revealed by luminescence dating, mineral magnetism and diffuse reflectance spectroscopy of river terrace palaeosols: a new form of geoproxy data for the southern African interior
Provedor de dados: 5
Autores: Lyons, Richard; Tooth, Stephen; Duller, Geoff A. T.
The nature, spatial patterns and forcing mechanisms of Quaternary climatic changes across southern Africa remain unresolved and contentious, principally due to the scarcity of continuous and robustly-dated proxy records. We present what we interpret to be a broadly continuous record of late Quaternary climatic change based on optically stimulated luminescence (OSL) dating, and mineral magnetic and diffuse reflectance spectroscopy (DRS) analyses of stacked palaeosols within an overbank alluvial succession along the Modder River, central South Africa. The OSL ages indicate that alluvial sedimentation occurred at a fairly steady rate, averaging similar to 0.15 mm/yr from at least 44 ka until similar to 0.83 ka. This suggests that the palaeosols are...

Climatic variability in Mfabeni peatlands (South Africa) since the late Pleistocene
Provedor de dados: 5
Autores: Baker, Andrea; Pedentchouk, Nikolai; Routh, Joyanto; Roychoudhury, Alakendra N.
It has been postulated that a bipolar seesaw interhemispheric mechanism dominated the relationship between the Northern and Southern hemisphere climates since the late Pleistocene. A key test for this proposition would be to undertake palaeoenvironmental studies on terrestrial archives in climatically sensitive regions. Southern Africa's contemporary C-3 and C-4 terrestrial plant distributions display a definitive geographical pattern dictated by different growing season rainfall and temperature zones; however, the region is generally archive poor due to its overall semi-arid climate and high relief topography. The Mfabeni peatland, with a basal age of c. 47 k yrs calibrated before present (kcal yr BP), is one of the oldest continuous coastal peat deposits...

A late Quaternary record of seasonal sea surface temperatures off southern Africa
Provedor de dados: 5
Autores: Loftus, E.; Sealy, J.; Leng, M. J.; Lee-thorp, J. A.
The southern Cape coastal region is important for understanding both the behavioural history of modern humans, and regional and global climate dynamics, because it boasts a long archaeological record and occupies a key geographical location near the intersection of two major oceans. The western boundary Agulhas Current, implicated in global heat exchange dynamics, is an important modulator of southern African climates and yet we understand its past behaviour only broadly as the Current itself scours the coastal shelf and marine sediment core records necessarily provide little detail. Numerous archaeological sites from both the late Pleistocene and Holocene provide the opportunity for reconstruction of near shore seasonal SST records, which respond both to...

New species of Maerua (Capparaceae) from Angola
Provedor de dados: 16
Autores: Abreu, J.A.; Martins, E.S.; Catarino, L.
Genus Maerua has around 60 species represented on the African continent, of which three have been reported for Angola. Two new species of Maerua (Capparaceae) from Angola are here described. Both are closely similar to M. juncea subsp. juncea, being distinguished by floral traits such as the receptacle, androphore and gynophore (M. pintobastoae) or leaf traits such as venation, as well as size and shape of the ovary and disc shape (M. mendesii). A key for Maerua species occurring in Angola is provided, as well as a table summarizing and comparing the morphological characters for the new species and similar African species. With the description of these two new species, the genus Maerua comprises five species in Angola. Resumo O género Maerua tem cerca de...

Revision of the family Dipterocarpaceae in Angola
Provedor de dados: 16
Autores: Catarino, L.; Martins, E.S.; Abreu, J.A.; Figueira, R.
The diversity of Dipterocarpaceae in Angola is updated to 24 taxa, two species of Marquesia and 22 species and subspecies of Monotes. A new species is described and four new records (three species and one subspecies) are added to the Flora of Angola. The new species, Monotes paivae, occurs in the province of Bié, central Angola. Its diagnostic characters are a persistent indumentum on the entire upper surface of leaves and a woollytomentose indumentum in the lower surface of adult leaves. A key to the species and the respective descriptions is presented. The species of Monotes endemic in the country are mapped and their conservation status is discussed.

Comparative reproductive anatomy in the South African giant land snails (Gastropoda: Pulmonata: Achatinidae)
Provedor de dados: 16
Autores: Mead, A.R.
The history and current taxonomic status of 62 nominal taxa are revised that have been associated in the literature with the subgenus Tholachatina Bequaert, 1950, of genus Archachatina Albers, 1850, and the genus Cochlitoma Férussac, 1821, in the land snail family Achatinidae Swainson, 1840. Tangible, reliable characters have been found in the detailed features of the reproductive anatomy in this family. The results of comparative anatomical study convincingly reflect phylogeny in contrast to the comparative study of only the shell characters. This latter more strongly reflects the effects of the intrinsically variable environment over time. In the present study, both sets of characters are needed to refine identification.  Change, and therefore...

Micro-Level Analysis of Farmers’ Adaptation to Climate Change in Southern Africa
Provedor de dados: 31
Autores: Nhemachena,   Charles; Hassan,   Rashid M.
Adaptation to climate change involves changes in agricultural management practices in response to changes in climate conditions. It often involves a combination of various individual responses at the farm-level and assumes that farmers have access to alternative practices and technologies available in the region. This study examines farmer adaptation strategies to climate change in Southern Africa based on a cross-section database of three countries (South Africa, Zambia and Zimbabwe) collected as part of the Global Environment Facility/World Bank (GEF/WB) Climate Change and African Agriculture Project. The study describes farmer perceptions to changes in long-term temperature and precipitation as well as various farm-level adaptation measures and barriers...

Poverty in Malawi, 1998
Provedor de dados: 31
Autores: Benson,   Todd; Machinijili,   Charles; Kachikopa,   Lawrence.
This paper presents the poverty analysis of the 1997-98 Malawi Integrated Household Survey. The analysis developed basic needs poverty lines, using consumption-based measures of welfare to classify households and individuals as poor and nonpoor. Because consumption data were not of uniform quality across sample households, the analysis made adjustments to derive a more accurate assessment of the incidence of poverty across the country. The analysis provides poverty and inequality estimates for Malawi's population. About 65 percent were unable to meet their basic needs, and poverty was deep and pervasive. The distribution of household welfare was closely examined within the context of the Malawi Poverty Reduction Strategy to guide government action in...

SHOULD REGIONAL TRADE LIBERALIZATION OF AGRICULTURE BE A POLICY PRIORITY IN SOUTHERN AFRICA?
Provedor de dados: 31
Autores: Nin Pratt,   Alejandro; Diao,   Xinshen; Bahta,   Yonas Tesfamariam.
We develop a detailed trade analysis to assess the potential impacts of a free trade agreement (FTA) on the agricultural sector of Southern African countries. We do this by combining the use of a partial equilibrium analysis with bilateral trade data at the four-digit Standard International Trade Classification (SITC) level for 193 agricultural industries in 14 Southern African countries. Results show that the overall welfare effects of a FTA would be positive but small in most countries. Largest benefits would go to countries with a regional comparative advantage for agriculture, while still being inefficient producers of regionally traded commodities. No direct gains for importing countries are expected because a FTA would increase imports from...

Labor requirements and profitability of alternative soil fertility replenishment technologies in Zambia
Provedor de dados: 31
Autores: Ajayi,   Olu Clifford; Akinnifesi,   Festus K.
Low soil fertility is a major concern in agricultural productivity and development policy discourse in sub-saharan Africa. The problem is exacerbated by government withdrawal from fertilizer input markets and the inability of private sector operators to fill the gap. This warranted a search for other nutrient sources to supplement chemical fertilizers. Based on field data collected in Zambia, this study assessed the labor inputs implications of “improved tree fallows”, continuous maize cropping with and without mineral fertilizer and, evaluated the financial profitability of the different land use systems. Results show that agroforestry-based land use systems are more profitable (NPV between $233 and $309 per ha) than farmers’ practice of continuous maize...

How Can Safety Nets Do More with Less? General Issues with Some Evidence from Southern Africa
Provedor de dados: 31
Autores: Haddad,   Lawrence James; Zeller,   Manfred.
This paper reviews design features by which safety nets might do more with less. It reviews the current evidence on their success in practice–including three brief reviews of southern Africa experience–and suggests a role for future policy research in furthering the goal of designing safety nets that reduce poverty in a cost-effective way. In doing so, the paper highlights a tension between the large gaps in our knowledge about the design of safety nets and the demand for short-run answers in this area.

Agricultural Trade Flows among Developing Countries: Do Regional Preferential Trade Agreements make a Difference?
Provedor de dados: 31
Autores: Tembo,   Gelson; Jayne,   Thomas S.
Regional integration through trade is recognized as one way to foster economic growth and poverty reduction. This paper uses the gravity model and 11-year panel data (1996-2006) on Southern African Development Community (SADC) member countries to study Zambia’s regional agricultural trade flows and the impact of the SADC Trade Protocol (SADC-TP). Zambia’s volume of trade is significantly related to most of the standard gravity variables. The results indicate that Zambia has been largely trading below potential, especially with respect to exports. There have been improvements in Zambia’s trade flows during the SADC-TP period but only with a few countries. Further improvements will require re-examining protocol implementation and individual countries’...

Rural Growth Linkages in the Eastern Cape Province of South Africa
Provedor de dados: 31
Autores: Ngqangweni,   Simphiwe.
This report addresses the impact of rising smallholder incomes on local nonagricultural development in the Eastern Cape of South Africa. It determines how increased rural incomes are spent on a mix of goods and services, and debates the implications of these spending patterns for growth in rural areas through the alleviation of demand constraints. These results make it possible to identify areas of intervention necessary for sustaining growth originating from stimulus to tradable agriculture from economic reforms. This report thus contributes to an emerging literature on the possible impact of promoting smallholder agriculture in South Africa on rural livelihoods.

Food Crises and Food Markets: Implications for Emergency Response in Southern Africa.
Provedor de dados: 31
Autores: Tschirley,   David L.; Jayne,   Thomas S.
Concern about humanitarian crises in southern Africa, especially in light of the surge in world food prices since 2007, has been accompanied by calls for direct government action in food markets. This paper reviews how Zambia, Malawi, and Mozambique handled private food markets during the food crises of 2001/02, 2002/03, and 2005/06, which may provide important lessons for the management of future crises. Lack of trust between government and traders can lead to behavior that undermines the interests of each and harms consumers and farmers; Malawi and Zambia have persistently fallen into this trap while Mozambique has partially avoided it. Empirical policy analysis can make an important contribution to resolution only within a consultative process involving...

Agri-food markets are restructuring, characterised by an increased consolidation and concentration of the industry, as supermarkets continue to expand at an exponential rate throughout the region. Unlike the global phenomenon where the formal markets are replacing informal markets, this is not so in the region. The informal sector is also expanding characterised by a significant level of restructuring. The major supermarkets have restructured their procurement strategies through the introduction of private standards, centralised procurement systems and distribution centres. Despite the increase in agri-food commodities emanating from the expansion of the retail sector, there have been little or no opportunities for smallholder farmers. The restructuring...

Regional Cooperation to Improve Food Security in Southern and Eastern African Countries
Provedor de dados: 31
Autores: Koester,   Ulrich.
Success in ensuring a continuous, adequate supply of food is one of the most important bases on which governments of low-income countries are judged by their people. This is because downward fluctuations in food supplies wreak great privation on low-income people and redistribute real income away from them. In view of this, the International Food Trade and Food Security Program at the International Food Policy Research Institute (IFPRI) has undertaken a series of studies of food supply management in developing countries. Among the policies considered have been schemes to compensate for fluctuations in food production and supply and in foreign exchange availability at the national, regional, and international levels. IFPRI's studies of food management...

WHY THE POOR CARE ABOUT PARTIAL VERSUS GENERAL EQUILIBRIUM EFFECTS - PART 1, METHODOLOGY AND COUNTRY CASE
Provedor de dados: 31
Autores: Wobst,   Peter.
The paper compares the effects of productivity growth in agriculture in a standard CGE model and an adjusted CGE model with special features in order to replicate partial equilibrium behavior of traded agricultural sectors within a general equilibrium framework. The fixed-price, partial equilibrium CGE model shows a strong multiplier effect so that total GDP, factor earnings, and household incomes increase with the productivity growth in agriculture. In comparison, the standard CGE model generates much more diverse sectoral behavior, stronger trade through shifts in the exchange rate, and a less equitable income distribution among farm and non-farm households.
