Land use and land cover change and system level analysis to guide sustainable intensification efforts in mixed crop-livestock farming system

December, 2023
Global

Changes in land use and land cover (LULC) are a major concern in Ethiopia. It has a significant impact on the environment, food and feed availability, and other ecosystem services and products for present and future generations. The effects of LULC change are particularly more pronounced in the highlands of Ethiopia, where the majority of the country’s cultivated land and livestock grazing occur, and competition between different land use decisions is a major concern.

Evaluating responses by ChatGPT to farmers’ questions on irrigated lowland rice cultivation in Nigeria

December, 2023
Nigeria

The limited number of agricultural extension agents (EAs) in sub-Saharan Africa limits farmers’ access to extension services. Artificial intelligence (AI) assistants could potentially aid in providing answers to farmers’ questions. The objective of this study was to evaluate the ability of an AI chatbot assistant (ChatGPT) to provide quality responses to farmers’ questions. We compiled a list of 32 questions related to irrigated rice cultivation from farmers in Kano State, Nigeria. Six EAs from the state were randomly selected to answer these questions.

Critical assessment of cocoa classification with limited reference data: A study in Côte d’Ivoire and Ghana using sentinel-2 and random forest model

December, 2023
Ghana

Cocoa is the economic backbone of Côte d’Ivoire and Ghana, making them the leading cocoa-producing countries in the world. However, cocoa farming has been a major driver of deforestation and landscape degradation in West Africa. Various stakeholders are striving for a zero-deforestation cocoa sector by implementing sustainable farming strategies and a more transparent supply chain. In the context of tracking cocoa sources and contributing to cocoa-driven deforestation monitoring, the demand for accurate and up-to-date maps of cocoa plantations is increasing.

Climate change and agriculture in eastern and southern Africa: An updated assessment based on the latest global climate models

December, 2023
United States of America

In this paper we present analysis on the recent historical trend in agriculture in the Eastern and Southern Africa (ESA) region, along with analysis of recent historical trends in temperature and precipitation. We also present 5 climate models and describe the possible future climates associated with these. We use these climate models with crop models -- for seven crops -- and bioeconomic models to further assess the impact on agricultural productivity throughout the region and how the agricultural sector will transform through 2050.

Predicted changes in distribution and richness of wild edible plants under climate change scenarios in northwestern Kenya

December, 2023
Kenya

Wild edible plants (WEPs) can provide diverse and nutrient-rich food sources that contribute to the health and well-being of communities worldwide. In northwestern Kenya, WEPs are vital dietary components for nomadic pastoral communities with limited access to diverse cultivated food crops. However, the increasing impact of climate change poses a threat to these valuable food resources, and their sustainable utilization remains precarious. Here, we assessed the potentially suitable habitats and richness of 23 selected WEPs in the region using a species distribution modeling (SDM) approach.

Guidance note: Setting gender responsive sustainability standards

December, 2023
France

Tackling gender inequalities is becoming increasingly important for voluntary sustainability systems to address. More and more, sustainability systems are looking to integrate gender into their standards and the management of their organisations. Sustainability systems that are not gender-responsive can result in unnecessary health and safety risks for women and girls, and lead to unequal impacts and unintended consequences.

Smallholder aquaculture diversifies livelihoods and diets thus improving food security status: evidence from northern Zambia

December, 2023
Zambia

Much has been made of the potential for aquaculture to improve rural livelihoods and food and nutrition security in Africa, though little evidence exists to back such claims. This study, conducted in northern Zambia, assessed the benefits of adopting aquaculture by comparing a sample of households with (n = 177) and without fishponds (n = 174).

Can sustainable management of land commons offer a nature-positive solution? Initial insights from land use-based above-ground carbon stock modeling in the Thoria Watershed, India

December, 2023
India

A wealth of publicly available satellite data and open-source models allowed researchers to measure carbon stocks in a watershed in India, despite a paucity of on-the-ground data. They found that despite rapid urbanization over the last 20 years, carbon stocks remained relatively stable – possibly due to successful reforestation activities. The research points to how nature-positive solutions can be designed and measured at scale. The research also lays the foundation for global studies to promote a deeper understanding of ecosystem services and sustainable land management.

Evaluation of exclosures in restoring degraded landscapes in the semi-arid highlands of northwestern Ethiopia

December, 2023
Ethiopia

Land degradation is a severe environmental problem in the northern and northwestern Ethiopian highlands. As a response to increasing land degradation, rehabilitation of degraded grazing lands through exclosures (exclusion of farmers and domestic animals) has been undertaken. This study aimed to evaluate the effectiveness of 11 and 8-year exclosures in improving degraded landscapes in the Karita-Wuha and Dengora watersheds. It was assumed that the conditions on communal grazing lands at the time of the investigation corresponded to those at the establishment of exclosures.

New podcast explores policy coherence and system transformation in food, land and water

December, 2023
Global

Overcoming future sustainable development challenges will require significant transformations in food, land, and water systems. However, the challenges faced by countries are varied and complex. Produced by IWMI, the Policy Pathways podcast will examine the policy coherence of food, land, and water systems in six of the CGIAR’s National Policies and Strategies Initiative countries.
