Conservation Agriculture Practices and Adoption by Smallholder Farmers in Zimbabwe AgEcon
Mazvimavi, Kizito; Ndlovu, Patrick V.; Nyathi, Putso; Minde, Isaac J..
This study is based on a panel survey interviewing 416 farmers practising conservation agriculture for at least five cropping seasons. Farmers obtained higher yields on conservation agriculture plots than on nonconservation agriculture ones. The mean maize yield on conservation agriculture was 1546 kg/ha compared to 970 kg/ha for non-conventional draft tillage plots across all 15 districts. However, the contribution of conservation agriculture to total household food security requirements was limited due to small plot sizes. Labor and land still remains a major challenge that limits the expansion of conservation agriculture area. Winter weeding remains a challenge, with 63% of farmers practicing it. Application of residues is still limited (56% of farmers...

Monitoring of Public Spending in Agriculture in Southern Africa AgEcon
Chilonda, Pius; Olubode-Awosola, Femi; Minde, Isaac J.; Njiwa, Daniel; Govereh, Jones.
Public resources are limited and have competing demands, hence prioritization will be critical. Policymakers want to know what public spending on agriculture sector will have the largest impact on the poor and how the resources should be allocated among the different sub-sectors. This brief examines the SADC region’s progress toward meeting the commitments made by African Heads of State and Government in the 2003 Maputo Declaration on Agriculture and Food Security to allocate at least 10 percent of national budgetary resources to agricultural sectors. Further, to build understanding of the challenges and opportunities facing governments as they strive to meet this target, the results of case studies of public expenditures on agriculture in Malawi and...

Promoting Fertilizer Use in Africa: Current Issues and Empirical Evidence from Malawi, Zambia, and Kenya AgEcon
Minde, Isaac J.; Jayne, Thomas S.; Crawford, Eric W.; Ariga, Joshua; Jones, Govereh.
It is generally agreed that increasing agricultural productivity is critical to stimulating the rate of economic growth in Africa. There are many important and often complementary determinants of agricultural productivity. In this brief and the full paper it draws from, the focus is on fertilizer and improved seed, without intending to imply that they are the only or most significant productivity determinants.

The use of participatory processes in wide-scale dissemination of micro dosing and conservation agriculture in Zimbabwe AgEcon
Pedzisa, Tarisayi; Minde, Isaac J.; Twomlow, Steve.
Participatory technology development has been used for quite some time. However, little is known about how farmers perceive participatory methods and processes. Understanding farmers’ concerns about the participatory process can be an important starting point and can further the ultimate aim of encouraging sustained technology adoption. An ex-post participatory technology development and transfer evaluation was carried out in Zimbabwe in 2006/07 involving 231 farmers. It was revealed that use of demonstration trials encouraged the most participation and subsequent adoption and adaptation of the technologies to suit specific needs. The participatory nature of the process encouraged greater knowledge sharing among farmers and gave them more confidence in the...

“Supply and demand trends for fertilizer in Zimbabwe: 1930 to date”: Key drivers and lessons learnt AgEcon
Minde, Isaac J.; Mazvimavi, Kizito; Murendo, Conrad; Ndlovu, Patrick V..
The fertilizer sector in Zimbabwe has evolved over the years in response to different policy changes based on the government’s priorities on agricultural development. The industry grew from the 1930s that targeted primarily large scale commercial farmers, through the liberalization period of the mid 1990s, and recent changes that have introduced controls on the marketing system. Since 2000, following the fast track land reform program, Zimbabwe has faced food insecurity challenges that have been exacerbated by the political and economic crises. This prompted the government to adopt policies that have reduced private sector interests in fertilizer supply. In this situation where explicit fertilizer markets have been absent, relief programs have been leading...

Promoting Fertilizer Use in Africa: Current Issues and Empirical Evidence from Malawi, Zambia, and Kenya AgEcon
Minde, Isaac J.; Jayne, Thomas S.; Crawford, Eric W.; Ariga, Joshua; Govereh, Jones.
This study was funded jointly by the Regional Strategic Agricultural Knowledge Support System (Re-SAKSS) for Southern Africa, based at International Water Management Institute, Pretoria, South Africa, and by the United States Agency for International Development's Africa Bureau. Much of the data and analysis reported in this study was carried out under the Tegemeo Agricultural Monitoring and Policy Analysis Project, funded by USAID/Kenya; the Food Security Research Project/Markets, Trade and Enabling Environment (MATEP) Program, funded by USAID/Zambia and the Swedish International Development Agency; and by the DFID and USAID offices in Lilongwe, Malawi.

Striving for Higher Impacts in Agricultural Research and Development AgEcon
Waithaka, Michael M.; Minde, Isaac J..
Over the years, substantial investments in agricultural research have been made in sub-Saharan Africa. The few studies on research investments show impressive returns that are comparable to those achieved in developed countries. However, problems such as recurrent hunger, poverty, food insecurity and natural resource degradation continue to plague the region. Agricultural development arena is changing rapidly toward non-linear innovation systems of complex actor networks and multiple sources of innovations characterized by dynamic and iterative learning processes that constantly inform, renew and advance the state of the systems. Most actors and institutions are not linked effectively often from imaginary boundaries created by prescribed mandates and...

Rationalization and Harmonization of Seed Policies and Regulations in Eastern and Central Africa: Effecting Policy Change through Private Public Partnerships AgEcon
Minde, Isaac J.; Waithaka, Michael M..
Cereal grains are important staple foods in Africa but yields are still too low at 1.5 tons per ha for maize while compared with a global average of 4.5 tons per ha. This can be partly attributed to limited development of commercial seed markets, low use of improved seeds, small and highly fragmented seed markets. Many released varieties are not widely disseminated due to closed national markets dominated by a few international companies and parastatals, and restrictive laws, regulations and policies. Transactions costs within and across national boundaries are high because of differing arrangements across countries. Establishment of common regulatory structures is expected to reduce transactions costs and promote increased trade and hence use of improved...

The 2008/09 Food Price and Food Security Situation in Eastern and Southern Africa: Implications for Immediate and Longer Run Responses. AgEcon
Jayne, Thomas S.; Chapoto, Antony; Minde, Isaac J.; Donovan, Cynthia.
The dramatic rise in world food prices since 2007 has commanded the world’s attention. However, in recent months, world food prices have fallen almost as rapidly as they had risen in late 2007 and early 2008, yet as is demonstrated in this report, domestic food price levels in many eastern and southern African markets are not closely tracking world prices. Fertilizer prices remain at unprecedentedly high levels and may have a critical influence on future food production levels in the region. Against this backdrop, there is an urgent need for information about how the current food situation is unfolding in the region, the immediate policy response options, and the longer-term challenges and opportunities. This study has three objectives: 1) to examine the...

The Economics of Biotechnology (Gmos) and the Need for A Regional Policy: The Case for COMESA Countries AgEcon
Minde, Isaac J.; Kizito, Mazvimavi.
Many countries in the world have adopted genetically modified organisms as products that can have great beneficial impact on agriculture, industry and trade. However, to date for the whole of Africa, only South Africa has commercialized genetically modified organisms (GMOs). Realizing the high transactions costs—particularly in trade that may underlie different countries having varying policy stances on biotechnology, COMESA (COMESA—Common Market for Eastern and Southern Africa, is a regional grouping of 20 countries. In the context of this study, Tanzania is also included although it is not a COMESA member. This is because it belongs to the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) of which nine countries...
