Recent estimates show that one third of the world’s land and water resources are highly or moderately degraded. Global economic losses from land degradation (LD) are as high as USD $10.6 trillion annually. These trends catalyzed a call for avoiding future LD, reducing ongoing LD, and reversing past LD, which has culminated in the adoption of Sustainable Development Goal (SDG) Target 15.3 which aims to achieve global land degradation neutrality (LDN) by 2030.

Inadequate land management and agricultural activities have largely resulted in land degradation in Burkina Faso. The nationwide governmental and institutional driven implementation and adoption of soil and water conservation measures (SWCM) since the early 1960s, however, is expected to successively slow down the degradation process and to increase the agricultural output. Even though relevant measures have been taken, only a few studies have been conducted to quantify their effect, for instance, on soil erosion and environmental restoration.

Land degradation poses a major threat to agricultural production and food security in Ethiopia, and sustainable land management (SLM) is key in dealing with its adverse impacts. This paper examines the covariates that shape rural livelihood diversification and examines their effects on the intensity of adoption of SLM practices. Household-level data were collected in 2017 from 270 households in three drought-prone watersheds located in northwestern Ethiopia. We used the Herfindahl–Simpson diversity index to explore the extent of livelihood diversification.

The extent of land affected by degradation in Uganda ranges from 20% in relatively flat and vegetation-covered areas to 90% in the eastern and southwestern highlands. Land degradation has adversely affected smallholder agro-ecosystems including direct damage and loss of critical ecosystem services such as agricultural land/soil and biodiversity. This study evaluated the extent of bare grounds in Nakasongola, one of the districts in the Cattle Corridor of Uganda and the yield responses of maize (Zea mays) and common bean (Phaseolus vulgaris L.) to different tillage methods in the district.

In this paper, we present a distributional impact analysis of climate change policies envisaged or implemented to reduce greenhouse gas emissions in Senegal. We consider policies implemented in developed countries and their impact on a developing country. Moreover, we simulate the diminishing productivity of agricultural land as a potential result of climate change (CC) for Senegal. This country is exposed to the direct consequences of CC and is vulnerable to changes in world prices of energy, given its lack of substitution capacity.

The widespread acquisition of land for large-scale/commercial production of biofuel crops in Ghana has raised concerns from civil society organizations, local communities and other parties, regarding the impact of these investments on local livelihoods. This paper assessed the effect of large-scale acquisition of land for production of Jatropha curcas on farmers’ livelihoods in Ghana. The study was conducted in 11 communities spanning the major agro-ecological zones and political divisions across Ghana.

Les perturbations climatiques, l’évolution démographique et les sécheresses des dernières décennies, ont contribué à une rupture d’équilibre entre les systèmes de production pastorale et agricole, au détriment des pasteurs. À côté de ce contexte écosystémique, d’autres facteurs viennent aggraver la situation pastorale dans le Sahel, en particulier le rétrécissement de l’espace pastoral, grignoté par l’expansion des terres agricoles.

Este tem como objetivo analisar os efeitos de uso consuetudinário e inaplicabilidade da Lei 5/98, e se tais fatores contribuem para a redução de acessoàs terras cultiváveispelas mulheres inseridas na agricultura de subsistência na Guiné-Bissau. O problema fundiário é uma preocupação global, tendo início na transição do sistema econômico feudal, quando um grupo minoritário detentor do poder controlava os meios de produção.

Ce numéro de « Regards sur le foncier » reprend une partie des communications présentées lors du séminaire régional sur la gestion foncière locale en Afrique de l’Ouest et à Madagascar, organisé en mars 2023 à Saint-Louis du Sénégal, à l’initiative du Comité technique « Foncier & développement » (CTFD). Ce séminaire a réuni soixante-dix participants, membres d’organisations de la société civile, d’organisations paysannes ou des administrations foncières, et experts-chercheurs, de huit pays d’Afrique (Bénin, Burkina Faso, Côte d’Ivoire, Guinée, Sénégal, Madagascar, Mali, Niger).

Opresente estudo teve como objetivo sistematizar os métodos tradicionais da produção do arroz da Etnia-Manjaca. O trabalho foi realizado por meio das entrevistas com agricultores familiares do Setor de Calequisse. Os resultados mostraramque o sistema da produçãonas terras altas é o que mais prejudica o ecossistemae a produção nas bolanhas é mais rentável.
