This suggests that even literatkre interventions are effective within the duration of the project, literature review on agriculture in ghana beneficiaries might be vulnerable literature review on agriculture in ghana variations in climatic and market conditions, potentially resulting in erosion of gains made during the life of the intervention.

Another concern with the interventions that reported yield change measurements is the lack of articulation of confounding factors. World Bnak Group 3rd Ghana economic update—Agriculture as an engine of growth and jobs creation.

In addition, even though malnutrition was inherent revied the motivation for most of the interventions, none of the included studies reported on changes in nutrition of target beneficiaries. In cases where project lifespan is short, the Government should develop the capacity and interest to take over or sustain successful interventions.

Majority of the included studies lacked temporal and homogenous data to enable analysis of impact over time. The relationships are not linear and indicates a complex interplay among biotic, abiotic, economic factors and yield. Crop losses to pests. Cumulative production for all crops supported by the NRGP programme primary axis and cumulative number literature review on agriculture in ghana farmers trained by the programme from to Effective use of water EUW and not water-use efficiency WUE is the target of crop yield improvement under drought stress.

This suggests that there was the need for the original or empirical materials to have discussed these factors in relation ln crop types. Supporting information S1 Table List of projects included in the review after literature review on agriculture in ghana processes and summaries of selected case studies.

In addition to the primary extraction and coding, an independent coder rated an adequate representation hhana the included studies to allow for the generation of inter-rater agreement data and provide an estimate of the reliability of the extraction and coding process. These are issues worth considering to guide future interventions and policy decisions.

Systematic review of the effects of agricultural interventions on food security in northern Ghana

What this suggests is that, although incomes increase for beneficiaries, low income households continue to earn relatively low incomes even after interventions, suggesting that currently food security interventions may be disproportionately benefitting those who are already outside the critical poverty level. Temperature and solar radiation effects on potential maize yield across locations. For the desktop search, peer-reviewed scientific publications were searched using key words, probable titles, and logical operators and filtering techniques.

Specifically, this paper sought literature review on agriculture in ghana systematically review the pooled effect of agriculture-related development interventions in Northern Ghana on food security from toand to synthesize the available information into a format usable for evidence-based policy and intervention design.

It is therefore important that interventions focus not only on measuring process goals but also measuring some outcome goals which would be relevant for evaluation of impacts on food security. There were strong relationships between income before and after implementation, and likewise between yield before and after implementation of food security intervention.

The Journal of Literature review on agriculture in ghana Science.

A large proportion of these interventions has been implemented or financed by development agencies and NGOs, with considerable spatial and temporal overlaps between interventions.

Methods and findings A systematic review was used to assess literature review on agriculture in ghana cumulative evidence of the effect of development interventions, implemented from to on food security, especially in Northern Ghana. Journal of sustainable development in Africa.

Results Description of included studies Information were retrieved from over 20 Government and non-Governmental organisations through online search and actual visits Table 1. Of those that reported good numerical information on increases in incomes, the unit of measurement was heterogeneous or inconsistent, making statistical analysis for similar crops difficult.

Finally, there is an issue of literature review on agriculture in ghana resilience of the intervention to the rapidly changing and harsh ecological conditions of Northern Ghana. It is concluded that evidence for impacts of the interventions on food security was weak, or largely assumed.

Systematic review of the effects of agricultural interventions on food security in northern Ghana

Received Mar 21; Accepted Aug 8. However, none of the studies retrieved for this review discussed any of these confounding factors in detail. Frontiers in plant science.

The impact of taxes literature review on agriculture in ghana subsidies on crop yields agricultural price distortions in Africa. Further, some studies undertook interventions related to infrastructure. Methodology The present study adapted the protocol developed by the Campbell Collaboration, which was used for a similar study by the Policy and Operations Evaluation Department of the Ministry of Foreign Affairs of the Netherlands [ 6 ].

While this region has savannah or ni conditions, with predominantly rain-fed agriculture, very few interventions focused on irrigation and storage facilities.
