Farmers commonly split large, undulating crop fields, even those at similar elevation range or contour, into a patchwork of small sub-plots in plane areas of Nepal. Specifically, to ensure irrigation or rainwater throughout their cultivated rice or wheat growing areas, structures like bunds, dikes, and ditches are commonly built. These structures not only require significant labor hours to build but also incur loss of some portion of productive crop areas.

The water-energy-food-ecosystem (WEFE) nexus is a cross-sectoral concept offering a holistic perspective of the interconnections among agriculture, energy production, water resources, and ecosystem health. However, most emerging nexus approaches have been narrowly focused on resource efficiency and technocratic ‘fixes’ that don’t adequately consider the impacts of resource use and development on diverse groups of resource users and managers.

This report presents the business plan designs and cost-benefit analyses for selected companies cooperating with the ‘transformational agroecology across food, land, and water systems’ programme, also known as the Agroecological Initiative (AE-I).In Mbire district, the sorghum value chain was prioritised because of the enthusiasm of the contracting company and positive results from the cost benefit analyses showing profitability for both the company and contracted farmers.

Soil and water conservation technologies are critical in reducing drought and soil erosion risks and increasing crop yields and incomes. Yet, there is limited empirical evidence on the extent and impacts of adopting soil and water conservation technologies in Tanzania. The study’s objective is to evaluate the adoption (as well as the duration of adoption) and the impacts of soil and water conservation technologies on income and food security in Tanzania.

The Amazon Basin features a vast network of healthy, free-flowing rivers, which provides habitat for the most biodiverse freshwater fauna of any basin globally. However, existing and future infrastructure developments, including dams, threaten its integrity by diminishing river connectivity, altering flows, or changing sediment regimes, which can impact freshwater species.

Crop yields in sub-Saharan Africa need to increase to keep pace with food demands from the burgeoning population. Smallholder farmers play an important role in national food self-sufficiency, yet many live in poverty. Investing in inputs to increase yields is therefore often not viable for them. To investigate how to unlock this paradox, whole-farm experiments can reveal which incentives could increase farm production while also increasing household income.

This article focuses on the results from trials developed to monitor the short-term effects of conventionally tilled systems versus CA on soil quality and crop productivity under conditions of the major cropping systems in central, north-central and north-eastern regions of Namibia. Conventional tillage (CT), Minimum tillage (MT), Minimum tillage, mulch (MT-M), Minimum tillage, rotation (MT-R) and Minimum tillage, mulch and rotation (MT-MR) were the primary treatments tested.

A 3-year field experiment was setup to address the threat of underground water depletion and sustainability of agrifood systems. Subsurface drip irrigation (SDI) system combined with nitrogen management under conservation agriculture-based (CA) maize-wheat system (MWS) effects on crop yields, irrigation water productivity (WPi), nitrogen use efficiency (NUE) and profitability. Grain yields of maize, wheat, and MWS in the SDI with 100% recommended N were significantly higher by 15.8%, 5.2% and 11.2%, respectively, than conventional furrow/flood irrigation (CT-FI) system.

The intensification of agricultural systems in sub-Saharan Africa (SSA) is necessary to reduce poverty and improve food security, but increased nutrient applications in smallholder systems could have negative consequences for water quality, greenhouse gas emissions, and air quality.

This training resource kit aims to support multi-stakeholder platforms and consortia at landscape level that aim to strengthen capacities for climate smart strategies and actions in food and agriculture. The training kit provides an introduction to a diversity of science-based tools and processes that can support climate smart approaches as well as practical support in how to collaboratively learn from each other in the process and co-create a roadmap for capacity strengthening in climate adaptation.
