Ethical issues involving long-term land leases: a soil sciences perspective
As populations grow and arable land becomes increasingly scarce, large-scale long- term land leases are signed at a growing rate. Countries and investors with large amounts of financial resources and a strong agricultural industry seek long-term land leases for agricultural exploitation or investment purposes. Leaders of financially poorer countries often advertise such deals as a fast way to attract foreign capital. Much has been said about the short-term social costs these types of leases involve, however, less has been said about the normative dimension of their long-term environmental impact. We therefore will focus on the likely impact such deals have for soil conservation, by (1) briefly introducing the basics of long-term leasing arrangements by comparing land leases to the renting of buildings, (2) explaining from a soil sciences perspective the difficulties in assessing the current value of an estate and in calculating the damages of soil erosion and degradation, and (3) show how difficult it is to incentivize the conservation of soil quality when one cannot sufficiently and cost-effectively valorize existing environmental capital and eventual future damages. Attempting to oblige tenants through contracts to invest in sustainable stewardship has limited potential when liability payments do not reflect true costs and are hard to enforce
Hurricane MarĂa: An Agroecological Turning Point for Puerto Rico?
When Hurricane MarĂa tore through Puerto Rico on September 20, 2017, it left 17 dead, 11,000 seeking shelter, and the islandâs 3.4 million people without power, water, or fresh food supplies.i It also ripped off the democratic veneer of the USâ âcommonwealth,â revealing the structural vulnerability of an island that has been colonized for over half a millennium. Disasters tend to unmask both unsustainable practices and inequitable relations of power. But they can also unleash the power of solidarity and self-governance as communitiesâabandoned by their governments and preyed upon by disaster capitalistsâcome together in unexpected ways. In the aftermath of Puerto Ricoâs worst social, economic and environmental catastrophe, the Puerto Rican food sovereignty movement is using agroecology to reconstruct the islandâs beleaguered food system
Slash-and-mulch: Exploring the role of shrub-based agroforestry systems for smallholder farmers in the Sahel
In Burkina Faso, degraded soils where no crop production is possible affect more than 1 million farmers (Bai et al., 2008). If restored, these soils could potentially contribute to increased local food provision and to climate change mitigation via global carbon sequestration. Advancements toward the imitation of dryland forest floors to restore agricultural soils in the Sahel, a form of âecosystem mimicryâ (Ewel, 1999), can be achieved via the intensive application of carbon-rich mulches. Therefore, strategies are needed to restore and maintain soil productivity via greater inputs of organic matter, greater water retention, reduced evaporation and runoff, increased soil biological diversity, and nutrient cycling and availability. Indigenous forms of agroforestry based on the use of local shrubs, as practiced by farmers, offer opportunities to design sustainable farming systems that are based on agroecological principles and can contribute to building resilience and adaptability in the face of climate change
Agro-ecology: beyond food
Some may view indigenous communities as being conservative and backwards. However, the Kabekwa in Costa Rica show that such communities can be adaptable and innovative. In response to changing circumstances, this community has been adapting its farming practices constantly, benefiting from it in multiple ways.
In this case study we show some of the additional advantages agro-ecology provides to farmers beside food. Using the concept of meaningful work we explore how knowledge-intensive farming stimulates the development of skills, improves self-determination and provides incentives for younger generations to work on the land
Adapting Food Production to Climate Change: An Inclusive Approach
On why agricultural innovation from the Global South can and should be used to adapt food production to climate change. Discussed on hand of three cases studie
Learning Agroecology Online During COVID-19
Since March 2020, the COVID-19 pandemic propelled the âstay-at-homeâ policy worldwide under public health uncertainty, resulting in increased individualization, as well as an increased reliance or dependency on digital communication technology. Based on a review of existing literature alongside a reflection on personal fieldwork experiences, we aim to: (1) describe major elements of agroecological pedagogy, (2) explore adaptation pathways to combine digitalization and participatory action-learning, and (3) briefly discuss opportunities and challenges for agroecologists beyond COVID-19. Agroecological pedagogy is deeply embedded in the praxis, the scientific knowledge and ways of knowing (academic or not), and in the politics and agency of food movements. In line with Freire's liberation pedagogy, seeing what already exists (e.g., in: ecosystems, home-gardens, fields, farms, and watersheds) through participation and volunteering. Alongside a critical analysis to explain and explore certain phenomena, causes and consequences will likely result in the act leading to the implementation of transformative practices and novel designs that improve the state of any situation being addressed. Participatory action research/learning methods are strategic in agroecological pedagogy. Overall, the lockdown period led to increased societal digitalization of human interactions. During lockdown, however, the implementation of strategies for remote agroecology participatory action-learning were hampered, but not vanquished. Key changes to agroecology education projects âbeforeâ and âduringâ lockdown include an increased reliance on digital and remote strategies. Creative adaptations in the virtual classrooms were designed to nurture, deepen, and foster alternatives in favor of diverse knowledges and ways of knowing for food system transformations
Use and management of biodiversity by smallholder farmers in semi-arid West Africa
Strategies that strengthen and use biodiversity are crucial for sustained food production and livelihoods in semi-arid West Africa. The objective of this paper was to examine the role of biodiversity in sustaining diverse forms of multifunctional farming practices while at the same time providing ecological services to subsistence-oriented farming families in the region of study through mechanisms as (a) crop species diversification, (b) management of spatial heterogeneity, and (c) diversification of nutrition-sensitive landscapes. Our analysis shows that crop associations between cereals and legumes or between perennials and annuals, have overall positive effects on soil characteristics and often improve crop yields. Soil heterogeneity is produced by woody perennials and termites. Local management provides opportunities to collect a diversity of nutrition-rich species year-round and sustain household nutrition.</p
