Gold mining is a tremendously important economic activity in rural districts of Ethiopia. We assessed the impacts of artisanal gold mining on soil and woody vegetation in northern Ethiopia. Estimation of soil loss, plant inventory, group discussions and transect studies were used to address the research questions. We employed t‐test to compare woody species and soil loss between mined and unmined sites. Moreover, we ran one‐way ANOVA to compare the average volume of soil loss among the mining sites. The study shows that gold mining removed colossal volumes of soil from the mining landscape with a significant difference among gold mining sites (P ≤ 0.05). Soil loss between the mined and unmined sites was also significant (P ≤ 0.05). Moreover, gold mining destroyed massive tracts of vegetation. Woody species encountered at plot level decreased from artisanal gold mined to unmined sites (P ≤ 0.05). Moreover, dead trees and exposed tree roots were higher in mined than the unmined areas (P ≤ 0.05). This discouraged regeneration and recruitment of woody vegetation. To conclude, gold mining system converted vegetated sites and farmlands into dysfunctional landscape. Therefore, we suggest that combined rehabilitation efforts are required to overcome the challenges of artisanal gold mining on sustainable land management in northern Ethiopia.

HighlightsTrials were conducted in highland and medium-highland coastal locations.On highlands, increasing inputs boosted yields and GHGs in HYV rice, and USG at 50 kg N ha−1 produced similar yield and economic efficiency as 75 kg N ha−1 prilled urea in highlands.Deep-placed urea did not generate higher profits on medium-highlands.Little N response occurred on medium-highlands with a traditional variety.This variety was associated with reduced energy requirements and GHG emissions.

Pigeonpea is a major pulse crop in India. However, its productivity, which hovers around 700 kg ha -1 , has remained stagnant over the past several decades. Local landraces dominate the cultivation of pigeonpea in the country. A major reason for low productivity in pigeonpea is the non-availability of quality seed of improved varieties to farmers. In this paper, we share experiences of farmer-participatory pigeonpea seed production in Fatehpur and Kanpur Dehat districts in Uttar Pradesh in India. Through farmer-participatory varietal selection trials, farmers identified NA 1, long-duration pigeonpea variety and UPAS 120, short-duration variety, as their preferred choices. Long-duration variety NA 1 was preferred because of its disease resistance, higher yield, attractive seed size and color. Farmers were organized to form cooperative societies to undertake seed production, processing and marketing at the local level. Societies were also linked with the public sector seed producing agencies to participate in the formal seed production program. The C: B ratio of seed production of NA 1 variety was 1: 5.19 as compared to 1: 2.53 of the local variety. Village-level seed production not only addressed the issue of shortage of quality seeds but also brought higher incomes to farmers leading to improved livelihood.
