Public–private partnership generates economic benefits to smallholder bean growers in Uganda

december, 2022
Uganda

The quest to transform and hasten the role of smallholder farms in agricultural development and food security through farmer firm linkages has dominated development interventions in low-income countries for several decades. This has mostly been pursued through single- or multi-contract schemes implemented in isolation. Several studies have analyzed the efects of these schemes on smallholder farms with mixed results. A new paradigm is to use Agricultural Public Private Partnership (Ag-PPP) to achieve wider and sustainable impacts.

Heat-tolerant maize for rainfed hot, dry environments in the lowland tropics: from breeding to improved seed delivery

december, 2022
Global

Climate change-induced heat stress combines two challenges: high day- and nighttime temperatures, and physiological water deficit due to demand-side drought caused by increase in vapor-pressure deficit. It is one of the major factors in low productivity of maize in rainfed stress-prone environments in South Asia, affecting a large population of smallholder farmers who depend on maize for their sustenance and livelihoods.

Changing dynamics in the spread and management of banana Xanthomonas wilt disease in Uganda over two decades

december, 2022
Uganda

Banana Xanthomonas wilt (BXW) is a destructive disease caused by Xanthomonas vasicola pv. musacearum (Xvm) bacterium that indiscriminately infects all banana varieties grown in East and Central Africa (ECA). In this region, BXW was first reported in 2001 in Uganda and was projected to eliminate >90% of Uganda’s bananas worth US$4 billion if not controlled in less than 10 years. Lack of basic information led to application of control approaches that were based on similarity of BXW symptoms to those of Moko disease of bananas.

Big data, small explanatory and predictive power: Lessons from random forest modeling of on-farm yield variability and implications for data-driven agronomy

december, 2022
Global

Context
Collection and analysis of large volumes of on-farm production data are widely seen as key to understanding yield variability among farmers and improving resource-use efficiency.
Objective
The aim of this study was to assess the performance of statistical and machine learning methods to explain and predict crop yield across thousands of farmers’ fields in contrasting farming systems worldwide.
Methods

Influence of production situation on the incidence of brown spot of rice (Oryza sativa) caused by Bipolaris oryzae in the Philippines

december, 2022
Philippines

Brown spot, caused by Bipolaris oryzae, is becoming more prevalent and important in the Philippines but risk assessment is limited. Surveys of 2186 farmers' fields were conducted in the major rice‐growing areas in the country from 2015 to 2018 to analyse the components of production situation (PS) that contribute to the area under the progress curve of brown spot incidence (aBS). Based on lasso regression, the components of PS that influence aBS, in decreasing order, are ecosystem (irrigated vs. rainfed), crop establishment method (direct seeding vs.

Stakeholder Analysis: Prospects for Effective and Sustainable Implementation of Innovation Packages, Achieving Initiative's Immediate Results and Outcomes in Mali

december, 2022
Mali

This report aims to provide a structured analysis of a stakeholder assessment related to
sustainable animal productivity for livelihoods, nutrition, and Gender Inclusion in Mali. This
analysis is part of the CGIAR initiative SAPLING, with the primary goal of understanding and
identifying the role of various stakeholders, their potential contributions, and avenues for
collaboration to ensure the successful implementation of SAPLING’s innovation packages
(IP) and the desired outcomes of the initiative. This work aims at: i) Identifying wich relevant

Climate Risk Management in Agricultural Extension Curriculum Validation and Training of Trainers Workshop in Kenya

december, 2022
Kenya

Climate change and year-to-year climate variability have resulted in widespread, pervasive impacts to ecosystems and people in Africa, including increases in the intensity of weather extremes such as droughts and floods. While these shifting and varying temperature and precipitation patterns have affected the productivity of many climate-sensitive sectors, the agricultural sector has been the most impacted, resulting in reduced food availability and increased food prices, ultimately jeopardising food security, nutrition, and livelihoods of millions of people.

The enviro-champs: establishing a framework for a technologically upgraded environmental monitoring network at community scale

december, 2022
Global

The Enviro-Champs initiative was developed as a community driven, citizen science initiative in Mpophomeni township in Kwa-Zulu Natal (KZN), South Africa. Over time, the scope of work done and data collected by the Enviro-Champs has expanded. There is now recognition both locally and globally that the Enviro-Champs initiative shows great promise for national and global upscaling. However, several areas within the initiative remain where it could be improved, especially technologically.

Understanding capacities to scale innovations for sustainable development: a learning journey of scaling partnerships in three parts of Africa

december, 2022
Global

Finding out how to scale innovations successfully is high on the agendas of researchers, practitioners and policy makers involved in agricultural development. New approaches and methodologies seek to better address related complexities, but none of them include a systematic perspective on the role of capacity in (partnerships for) scaling innovations. We posit that this has left an important topic insufficiently addressed in relation to partnerships for scaling innovations.

Tailored forecasts can predict extreme climate informing proactive interventions in East Africa

december, 2022
Global

Abstract This commentary discusses new advances in the predictability of east African rains and highlights the potential for improved early warning systems (EWS), humanitarian relief efforts, and agricultural decision‐making. Following an unprecedented sequence of five droughts, 23 million east Africans faced starvation in 2022, requiring >$2 billion in aid. Here, we update climate attribution studies showing that these droughts resulted from an interaction of climate change and La Niña.

Jobs in the circular bioeconomy under scrutiny: the challenging reality of compost production in Rwanda

december, 2022
Rwanda

Today, most African countries have dysfunctional municipal waste management system, negatively impacting the environment and human health. However, as most of this waste is recyclable, informal actors are making their income out of the collection/sorting of waste. Accounting for the risks involved in waste manipulation, it is important to ensure decent working conditions for those recycling it.

Effect of mineral fertilisation on tuber yield and quality in yams (Dioscorea alata and Dioscorea rotundata)

december, 2022
Global

This study assessed mineral fertilisation impact on tuber yield and food quality in yam genotypes—Dioscorea alata and Dioscorea rotundata. Four genotypes, each from D. alata and D. rotundata, were used in field experiments conducted in Ibadan, Nigeria, during the 2017 and 2018 cropping seasons. Experiments were conducted under low soil NPK fertility conditions with and without Fertiliser treatments. Plots subjected to fertiliser treatment received recommended NPK rate for the area.
